JSP :: How To Load A Properties File
Jul 21, 2014
I am using JPF controllers. Already, i am loading a properties file in the controller
(using annotations @Jpf.Controller(messageBundles = { @Jpf.Message Bundle(bundlePath = "validation.validator.Messages") },).
I have a problem. Depending on one of the request variables, i need to load different properties files. All these property files have same keys, but with different messages. I need to take the user to different sites(though internally, the backend logic remains same...Look and feel of the front end along with messages to be shown change to make the users feel they are being directed to a different site).
I am thinking of loading the properties file from the JSP when the user logs in first time from login page so that these properties are available until the session expires & not read the properties file in Controller.

I'm developing an Applet that print a bar code using Jpos API. I need some jars and two configuration file. I've added jars to the classpath and configuration files in src directory. In Eclipse everything works fine.
DefaultProperties prop = new DefaultProperties();
prop.loadJposProperties();
SimpleXmlRegPopulator xmlReg = new SimpleXmlRegPopulator();
xmlReg.load(wincor.jpos17.THxxx.xml");
Everything works fine in Eclispe but I can't find property files when i call the applet from a web page. So I've checked the JavaPos sources and I've paste the loadJposProperties() and xmlReg.load("wincor.jpos17.THxxx.xml") content in my source code:
InputStream isD = prop.getClass().getClassLoader().getResourceAsStream(prop.JPOS_PROPERTIES_FILENAME); // (1) content of loadProperties
if (isD != null){
System.out.println("jpos/res/jpos.properties found");
[Code] ...
The same method is used to found wincor.jpos17.THxxx.xml. So when I call applet form the browser I get INPUT STREAM FROM PROPERTIES OK!! from (1) and jpos/res/jpos.properties not found from (2).
So getClass().getClassLoader().getResourceAsStream works if i write it directly in my code, but doesn't work if i call a jar method.

I'm not too familiar with serialization.It actually I found at this site (Java - Serialization) says that it will write and read properties of an object. I'm not quite sure how this would work as I would have thought that writing it to a text file would just do a toString() when you wrote it, but the page seems to think otherwise, and also names it .ser or something instead of .txt.
I thought, maybe this would work with my idea for a notepad that could store a Font, font color, and other settings, for the file. It would be beyond normal notepads. However, could you do this for a file as it would store text plus other things.
The upshot of this is that the same file, I was hoping to be able to be read by regular text programs like Notepad. However, could Notepad read such a modified file? Also, if notepad wrote to it, would it destroy my font properties and stuff that I'd add to it?
Also, what does this mean:
Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans™ has been added to the java.beans package. Please see XMLEncoder.
Originally, I was going to use FileAttribute or something like that but it looked hard to do and likely not what I wanted. However, this looks more like what I want, but I'd like to know. This could be a huge breakthrough for a lot of things I was hoping to do but never could think of an efficient way to do.
Update:This serializable thing works great for my text editor but it won't work too hot if another program like Notepad reads it as it will appear like gibberish, including the text.
I had thought of having it make two files, one regular, and one that was serialized, to deal with this, but this doesn't work if I try opening a file that another text editor created that might not have this other serialized version of the file.
Also, I haven't yet tried extending File itself yet. However, I still don't see how it would work the way I'd hoped.
In a way, I want it to be like a RTF with some things used to set te font of the text area when loaded but be able to deal with opening a file made by another text editor and also have another text editor be able to read it even if my text editor created it.

Need to know how i can store a value in File which is in Properties?
Here I am placing my Properties code :
ReportHTML C:/bea/user_projects/domains/OICDomain/applications/IIMS/IIMS/target/source/REPORT_HTML_DUMP/
ReportEXCEL C:/bea/user_projects/domains/OICDomain/applications/IIMS/IIMS/target/source/REPORT_EXCEL_DUMP/
My Java File :

try {
File configFile= new File("C: Documents and SettingsstudentMy DocumentsNetBeansProjectsCDASsrcconfig.xml ");
DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
Document doc = dBuilder.parse(fXmlFile);
doc.getDocumentElement().normalize();
NodeList nList = doc.getElementsByTagName("config");
[Code] .....
This code is working properly but i have use path like this
File configFile= new File("srcconfig.xml");
Instead of system directory path i have to use path inside of project but i am getting an error-cannot find the specified file...

In my java app there is a code which reads the properties file from src/main/resources folder.
Java Code:
@Component("mailerProperties")
public class MailerProperties {
private static Properties properties;
public MailerProperties() {
properties = new Properties();
[Code] ....
Now I need to create a jar file and also remove the properties file from src/main/resources folder and place it outside the jar file(in the same location as jar file) so that data inside it can be changed easily in future.
Question: Currently it uses ClassPathResource("mailer.properties") to read the prop file. What change I need to make to read it from outside the jar file...

The code for my button is below - I know it is wrong and that I need to change line 8 at least,so I am technically asking the property object if there is a key_name there but I dont quite get how to do that
//code for button
JButton btnSearch = new JButton("Search");
btnSearch.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
//find selected command
String key_name = textFieldSearch.getText();
[Code] ....
I basically just want the user typed in word to be checked against a keyword in a properties file and if it exists, pull the key and the value back into a panel

I have `country.properties` file which have values as follows:
1=USA
91=India
20=Egypt
358=Finland
33=France
679=Fiji
and, have a response class file, which is setting a response from database to display it on `JSP` file. The value that I am getting from database is in the form of `code` or `integer`. I needed to have that value from the database and before setting the response I need to use `getProperty(code)` and save the String representation of that code into a new list and then pass that list to `setResponse`. For e.g: This is the value I am getting from database:
col1 | col2 | col3 |
1 helo done
I needed to show on my JSP page as:
col1 | col2 | col3 |
USA helo done
I was following this tutorial [URL].... but not able to exactly understand how to achieve the same.
This is my `DAOImpl` where I needed to `iterate` and save the `mapped key-value` in a new list and then pass to `JSP` page
public class CountDAOImpl implements IDataDAO {
private Connection conn = null;
private Statement statement = null;
private ResultSet rs = null;
private List<String> country_code = new LinkedList<String>();
[Code] ....

I'm currently working on a java project simply to learn java. So far, it creates a window and makes a properties file, or appends data to it if it already exists. The problem is that I'm not quite sure how to check if the file already exists to append data to it. I'm currently using a boolean (configCreated) that appends data when true, and creates a file when false. The problem is that this boolean is always false since it's at the beginning.
Java Code:
package Setup;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.OutputStream;
import java.util.Properties;
[code]...

When we have a property in the jnlp file that has accented characters (i.e. Mañana), the System.getProperty() call is returning null. This is working fine with Java 7 Update 40, and accented characters in the <information> section of the jnlp file are working fine under Java 7 Update 45, but not in the <resources> section.
Here is an example:
<property name="jnlp.title" value="Mañana"/>
System.getProperty("jnlp.title") returns null
Is there a workaround?

I need to write the exact directory path like C:LisaestUpdate to a properties file.
I am trying it by
FileInputStream in = new FileInputStream(test.properties);
Properties props = new Properties();
props.load(in);
in.close();
FileOutputStream out = new FileOutputStream(newprop.properties);
props.setProperty("myDirectory","C:Lisa estUpdate" );
props.store(out, null);
out.close();
but the properties file is updated as C:Lisa estUpdate
Extra comes before :.
How can I remove that.
Even I tried it with an command but got same output.

I have a properties file with key values in it, now when I use my search box to search for a key in the properties file to check whether or not it is there - I can't get it to check and return the key value if it is theere. I've tried a few methods but keep getting a null pointer exception when it hits line 15 in the code all the time so I'm stumped at the minute.
My text field is called textFieldSearch
This is my button code
JButton btnSearch = new JButton("Search");
btnSearch.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
//search button
//find selected comman
String key_name = textFieldSearch.getText();
[Code] ....
This is my method code
public void FindSelectedKey()
{
if(textFieldSearch != null)
{
properties.getProperty(key_name == textFieldSearch)
}
}

I have a small application that I have been working on for several months. It works great. Now when I created an executable .jar file for it, it will not load data from a .csv file. I have tried looking into everything I can think if. I checked file paths, etc. I am using OpenCVS to read the csv. Is there an issue with that when you include it into another .jar file? I am trying to log if there is an error but I don't even get an error. I just doesn't run past that statement...

I'am trying to finish my first Java Game with the slick2D library. I had it all working in eclipse but when i was about to make a jar file of it i did realize that i had to use class loader to load my png - SpriteSheets. But now to the problem. My ResourceLoader Class looks like this:
public static InputStream load(String path){
InputStream input = MyResourceLoader.class.getResourceAsStream(path);
if(input==null){
input = MyResourceLoader.class.getResourceAsStream("/"+path);
}
return input;
}
My init-Method in the BasicGame class, where i try to load my png-files looks like this:
public void init(GameContainer arg0) throws SlickException {
InputStream inputStream1 = MyResourceLoader.load("images/piratR.png");
sprite1 = new SpriteSheet("",inputStream1,32,32);
InputStream inputStream2 = MyResourceLoader.load("images/monkey.png");
sprite2 = new SpriteSheet("",inputStream2,32,32);
animation1 = new Animation(sprite1,200);
animation2 = new Animation(sprite2,250);
}
And that works fine for loading the FIRST png-file(eg piratR.png), but whenever i try to load another file it just loads the first one again. So in this case sprite1 and sprite2 looks the same though there are different images.
When i switch the "Load order" and Load sprite2 before sprite1 both animations looks different, so I'm sure that i have two different pictures and its always the one that i load first that will get loaded to all the other SpriteSheets.

I can not load my jar file and it is telling me it can not find the main and I thought I had the right files in the right spots. Do I need the .class of my main file for it to make the jar file. I do not understand If I need to make a .jar out of the main then add all the other files to create the jar.
added manifest
adding: Board.class(in = 2431) (out= 1371)(deflated 43%)
adding: Cell.class(in = 1702) (out= 959)(deflated 43%)
adding: Mark.class(in = 1195) (out= 673)(deflated 43%)
adding: Outcome.class(in = 960) (out= 538)(deflated 43%)
adding: Player.class(in = 832) (out= 472)(deflated 43%)

I'm trying to load a class file into Oracle using loadjava and I get the following error:
ORA-29552: verification warning: java.lang.UnsupportedClassVersionError: helloworld (Unsupported major.minor version 51.0)
Presumably this is related to an inconsistency between the jdk that I used to compile helloworld and the Oracle JVM? Or something like that?
My JAVA_HOME is C:Program Files (x86)Javajre7bin
My javac version used to compile the code is javac 1.7.0_15
java -version is "1.7.0_15"
When I do a find on java.exe in the oracle installation directory (I'm running 11.2) I get
J-PC:J >find -name java.exe
./product/11.2.0/dbhome_1/jdk/bin/java.exe
./product/11.2.0/dbhome_1/jdk/jre/bin/java.exe
./product/11.2.0/dbhome_1/jre/1.5.0/bin/java.exe
Finally, the jdbc jar is ojdbc6.jar
Btw the code is just the usual little tester:
import oracle.jdbc.driver.*;
public class helloworld {
public static String hello()
{
return "Hello World";
}
public static String hello(String s)
[Code]...
How can I get this class file loaded?

I am trying to load a CSS file from a mySql DB table (each row represent a customer that use the application, and each one can set his own CSS file).
How can I convert the Stream / String that I loaded from the Clob column to something that I can use here XXXX
scene().getStylesheets().add( XXXX );
I found alot of examples, but they all talking about files from filesystem, or URLs. My CSS file is in the application memory. I want to prevent the option to write my string as a new file and then read it again. I have no problem with loading the CSS file from database, this part is O.K.

Whenever I try to write a file to the disk and then load it within the same Class (if it is even possible) ...
It gives me an error: Could not find the main class: score.Score. Program will exit.
I have tried this with 2 different classes and it works fine? Why that error is appearing.
Code:

I have an XML doc that looks like this:
Java Code:
<?xml version="1.0" encoding="UTF-8"?>
<model>
<id>_1</id>
<nodes>
<id>_2</id>
<stencil>TASK</stencil>
</nodes>
<nodes>
<id>_3</id>
<stencil>TASK</stencil>
</nodes>
</model> mh_sh_highlight_all('java');
I have to create another xml doc with the properties of nodes from the first doc. For the new doc I have to create a parent node called "definitions". Instead of the "model" node in the first doc I have to create a "process" node in the new doc that has an attribute "id" which value is the same as the content of the "id" child node of model. For each "nodes" node in the first doc if their "stencil" child node content equals "TASK" I create a "task" node in the new xml doc.
Java Code: <?xml version="1.0" encoding="UTF-8"?>
<definitions>
<process id="_1">
<task id="_2">
</task>
<task id="_3">
</task>
</process>
</definitions> mh_sh_highlight_all('java');
[code]....
I just wanted to know if this is the correct way to define the respective classes.any way to create and fill the nodes for the new doc using this classes? I am used with DOM parser and I know how to create nodes and fill attribute values, but I have always done this job in a single class, not using different classes for the elements.

I currently have some code using a JFrame. I am trying to access the items in a JList to save them in a TXT file. For this, I am using a "for" loop. The problem is, is that when I try to access the list items, I can't access them. The way I am trying to access the items is by using:
Java Code: listRight.getModel().getSize(); mh_sh_highlight_all('java');
BUT, I can't seem to get this to work. I tried to place this for loop everywhere and I can't access it. I tried accessing it under "public class Window", "private JFrame frmPcPartBuilder", "public static void main(String[] args)", "public void Initialize()" and I can't seem to access the JList. I basically have a save button that saves the list to a text file and the code I am trying to write is called by this button.
Java Code: package com.cooksys.assessment;
