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.
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.
I'm using HTMLEditor in my simple test application and I'm showing html text generated. I noticed that accented letters (à,è,ì, ect) are not escaped (àect ect). Looking at the source code I arrived to the class
com.sun.webkit.WebPage
In which the method I thinked is used is this:
public String getHtml(long frameID) { lockPage(); try { log.log(Level.FINE, "getHtml"); if (isDisposed) { log.log(Level.FINE, "getHtml() request for a disposed web page.");
File destHtmlFolder = new File("C:/bea/user_projects/domains/OICDomain/DOC_SERVER/REPORT_HTML_DUMP"); File srcExcelFolder = new File("C:/bea/user_projects/domains/OICDomain/applications/IIMS/IIMS/target/source/REPORT_EXCEL_DUMP");
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.
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
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>();

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.
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.
So I have 2 args[] one that reads the file name in the same directory and the other that tries to count how many of any letter (maybe even words) in the txt file ....
Whether it is possible to force the installation of JRE when trying to open JNLP file. It is quite often case when users try to run JWS application without JRE installed. The best option would be to force the installation or at least display some message with instructions. Perhaps there are different ways to handle this problem.
I am facing an issue with my java program, it is returning/storing file name with some junk characters i,e the file name with some '?','=' and '_'. Below is the example of file names.
Ex : abc.doc ab=?Windows-1252?Q?=c.do?c =?Windows-1252?Q? (prefixed with space) =?utf-8?Q? (prefixed with space) =?iso-8859-1?Q? (prefixed with space)
I am writing a custom jnlp installer for downloading our applications. We are having difficulty to specify our own cache directory. The default Download Service is not taking the below property. I was wondering if we need to extend any of the jnlp api classes and write my own. System.setProperty( "deployment. user.cachedir", "C://Users//f355668//AppData//Roaming//WorkBench//" );
The point of this program is to read characters from a txt file and store them into a 2D array. After this has been accomplished, the information is to be printed in the same manner it is read from in the txt file.
Here is the code I have so far:
import java.io.File; import java.io.FileNotFoundException; import java.util.Scanner; public class Main { public static void main(String[] args) throws FileNotFoundException
[Code] ....
And this is the error I am receiving when trying to accomplish the goal of the project:
Exception in thread "main" java.lang.NumberFormatException: For input string: "############" at java.lang.NumberFormatException.forInputString(Unk nown Source) at java.lang.Integer.parseInt(Unknown Source) at java.lang.Integer.parseInt(Unknown Source) at Maze.<init>(Maze.java:15) at Main.main(Main.java:20)
What's going on here and how I can correct this?? The information I am trying to store in a 2D array and then print is this:
Have an issue with deploying our application, which comes in two parts, with javaws . In our installer (which is coded in NSIS) we call javaws twice, each time referencing a different jnlp file. It looks like this:
I am new to work on JNLP program. I have created a SWING program, JNLP file when i deploy the ear file i am getting 404 error. Please find the steps in details.
1.Created a dynamic web project JWStartProject in eclipse
2.Create a HelloWorld.java class under default package.
import javax.swing.*; public class HelloWorld extends JFrame { private static final long serialVersionUID = 4968624166243565348L; private JLabel label = new JLabel("Hello Java Web START!"); public HelloWorld() { super("Jave Web Start Example"); this.setSize(350, 200); this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE ); this.setLayout(null);
[Code] ....
Now I exported this project as JWStartProject.war contains following code.
Created Server in Websphere Admin console
Deployed this war file under the server and started.
I have added MIME types also.
I am unable to launch the application. I am getting 404 errors. May I know where I went wrong?
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.
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:
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.
A triangle is defined by the x- and y- coordinates of its three corner points. Compute the following the following properties of a given triangle: the lengths of all sides, the angles at all corners, the perimeter and the area. The program must prompt a user for the point coordinates. I have created a class Triangle and a class TriangleSimulator, I am stuck and can't figure out why my program won't run correctly.
import java.util.Scanner; public class Triangle { Scanner in = new Scanner(System.in); private int x1; private int x2; private int x3;
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 am quite new to java and trying to print all the system properties with the following
code:System.out.println(System.getProperties());
This prints all the properties as expected but I am wanting to put each property on a new line and am struggling a bit. Obviously I will need some sort of for loop etc but im just not sure how to do it. Is it something along the lines of:
for (int i = 0; i < System.getProperties().size(); i++){
What my understanding of what the above is doing is checking how many properties there are an looping round for each property that exists, so all I need to do is get the property 1 at a time however I am not sure where to get the property value to input into the System.getProperty(); method.
