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.
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:
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 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.
Okay I am having a problem I wrote some code to transfer a file from my server when requested by the client. The problem is that when the file which is requested is transferred the file cannot be open in its respected file launcher when clicked. The File launcher throws back this msg "My Issue It request the File but after the File is requested and stored on the Client Machine when I Hit the File to be Launch adobe says the file "Adobe could not open the File for it is not supported file type or because the file as been damage"
So i have two pair sets of code for original coded by me. Original code i had first Server
import java.io.*; import java.net.*; public class SimpleFileServer { public final static String FILE_TO_SEND = "c:/Users/Acer/Downloads/COAFlags.pdf"; // you may change this public static void main(String args[]) {
I have a couple .java examples I want to mess with but don't know how to get them into Netbeans so I can work with them. What is the process in loading a .java into Netbeans so I can work with the code and run it in Netbeans?
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
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.
So the user is on a website and I want them to go to another site using the same browser and tab.Can this be done in java? And yes the java program is running on the browser .
Within my program I allow users to write their own code to be executed. I then save that code in a .java file and then compile. This gives me a .java file and a .class file within the same package in the src folder. However, the compilation process also creates a .class file in the build folder. When the user edits their code and then re-runs it, the .class file in the build folder does not get updated with the new data, but the .class in the src folder does.
What I want to do is to execute the .class file in the src folder and not the build folder. So far I have the following method, but that somehow refers to the .class file in the build folder:
public void runMethod(String packageFilePath, String className){ try{ URI fileURI = new URI("file:/src/uk/learningAid/UserInputs/"); URL url = fileURI.toURL(); URL[] urls = new URL[]{url};
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 have permanently set the path of bin of JDK 1.6 in the environment variables of my system. I am able to compile any of my java programs successfully. But when I give command to run the program I am getting an error "could not find or load main class".
When I write the command "set classpath=.;" program runs successfully. I want to know whether I have to set this classpath everytime I run a new progaram. Is there any permanent way to set classpath ?
I creates this simple code (shown below) inside a package of a major opensource code (i.e., openSHA), but when i run it the following error appears. The error mentions a class named "KT_testGmpeForScenarioRupture" that i wrote before and did not run showing exactly the same error.
Code:
package org.opensha.sha.gcim.imr.attenRelImpl; public class KT_Test { private static void main(String args) { int x=4; System.out.println("x is " + x); } }
Error: Could not find or load main class org.opensha.sha.gcim.imr.attenRelImpl.KT_testGmpeF orScenarioRupture
I am using RAD and I copied the Tomcat server from server to local folder. Then I tried to add this tomcat by adding new server. I got the error in title. After searching, I copied the Tomcatconf files to myworkspaceserver omcat at localhost-config, restart RAD and refresh. But now I am getting the error that the conf may corrupted or incomplete.
I have been trying to draw a bitmap image onto the canvas from Android and all it displays is a blank white screen. Whenever my app starts up, I am calling this in my game - view class which extends View and overrides the onDraw method:
I cannot get an image to display. The code here is my latest attempt. I have tried ImageIcon, applets using getImage() among many other things. I do not know if it is a file path problem. The file I am using is in the src folder of the package I am using on Eclipse. I am on Windows 8. Here is the code.
I am using Netbeans as my IDE and I have created a program called Saluton.java
I navigate to the folder holding the class file using the command line under Windows 7 but when I issue the command java Saluton.class I get an error it cannot load or find the main class.
