Runtime flags in jar file (java -D flags)

I need to start java with a runtime flag, this is how I do it from the DOS-promt on a NT box:
java -Dswing.disableFileChooserSpeedFix=true -cp myJarFile.jar MyMainClass
How can I put the runtime flag -Dswing.disableFileChooserSpeedFix=true into a manifest file?
// Mattias

You can't.
But it's a standard Javca Property that can be loaded off any file on the network.
So you probably should change your app to pick this property value by default.
Also try using an executable JAR file:http://java.sun.com/j2se/1.4.2/docs/guide/jar/jar.html

Done.
in my form i have created a bean_area and used as implementation class :ApiConn
in my formsweb.cfg i used this configuration: archive=frmall.jar,siberia_jpg.jar,ApiConn.jar,Hasher.jar,ReadCommand.jar,WriteCommand.jar,libAPI.jar
in my forms/java i have placed my jar files listed in the frmall.jar
i guess i am missing something but i dont know what it is.

JAR files + java.lang.NoClassDefFoundError

Hey all ...
I'm looking for little help with building JAR files. Here's the situation: (using ant script :))
I have few source files *.java which I include into JAR file with default MANIFEST built by ant. (these files should be implemented as LIBRARY.jar)
These files are classes, which I want to use in my Main.java class. But I want this Main, to be in independant executable JAR file, so I set Main-Class property to 'packagename/Main'.
Ofcourse in all files I have set package to my default package name. My question is, how can I force java to execute MAIN.jar and look for classes in my LIBRARY.jar
after executing command:
java -jar MAIN.jar I get java.lang.NoClassDefFoundError
Tanks for any ideas ...

Then all I can say in addition is that something isn't deployed correctly. You're not saying what class it isn't finding. For all I know it can't even find your main class to execute because maybe you don't have it deployed correctly in the right path structure within the jar. Or the path to LIBRARY.jar is wrong. Or some other problem. Don't know based on the portion of the error message you have displayed this far.

Cant use jar file - JAVA -

- JAVA -
Basically I have few files in one package in every one of them I worte:
"pack preyPackage;"
And I have some .jar file that I try to use. So I drag it into the oracle compiler, but I still couldnt use it. But if I delete the row:
"pack preyPackage;"
from each .java I able to use that .jar file.
my question is how can I still use that .jar file and package's all that other files..
Picture that shows the problem:
http://hwzone.co.il/community/index.php?action=dlattach;topic=290416.0;attach=92107;image
Thanks.

Tried it and get strange behaviours in JDev 10.1.3.3...
The latest version with sources can be found at
http://stwww.weizmann.ac.il/G-CS/BENARI/oop/index.html
You should get that one and modify the sources to include a package name.
I have little time to do that because I'm going on holiday for a week...

Simple but wierd java.lang.NoClassDefFoundError with jar file

I'm using ant to jar my .class files. My final objective is to create an executable jar. When I run my jar file - "java -jar PM.jar" - I get:
Exception in thread "main" java.lang.NoClassDefFoundError: pm/PMApp
This at least tells me that java found my MANIFEST.MF class and that is the correct class it should be looking for, but it doesn't seem to find the class. But when I do - "jar -tf PM.jar" - I get:
C:\mike\pm\execs>jar -tf PM.jar
META-INF/
META-INF/MANIFEST.MF
pm/
pm/EasterEgg.class
pm/JMSMessageListener.class
pm/PMApp.class
pm/ReleasePlanTest.class
pm/SystemArchitectureFrame$1.class
pm/SystemArchitectureFrame$2.class
pm/SystemArchitectureFrame$3.class
pm/SystemArchitectureFrame$4.class
pm/SystemArchitectureFrame$5.class
pm/SystemArchitectureFrame$6.class
pm/SystemArchitectureFrame$7.class
pm/SystemArchitectureFrame$8.class
pm/SystemArchitectureFrame.class
pm/SystemArchitecturePanel.class
Which shows me that the class is there. I suspected that it might have something to do with CLASSPATH at first because of the java.lang.NoClassDefFoundError, but now I am skeptical that that could be the problem. I even build a new jar file out of different classes to make sure my method was OK and that worked fine. Any ideas? Thanks for your help in advance.

Here is my Manifest:
Main-Class: pm.PMApp<carriage return>
Class-Path: C:/j2sdkee1.3.1/lib/j2ee.jar<carriage return>
I noticed that if I leave the Class-Path variable unset it has no problem finding the class pm/PMApp, but I then get a class loader error concerning J2EE stuff. Am I missing something in my Class-Path? I tried to even specify the jar file I'm running here, but that didn't work either? I have also tried '.' and './', space delimited in my Class-Path, like this:
Class-Path: . ./ C:/j2sdkee1.3.1/lib/j2ee.jar<carriage return>
Thanks for the replies, do you have any more suggestions?

How Can i open Html file in a Browser from Jar file

Unable to access classes in third party jar files packaged with my ejb.jar

I have packaged some third party jar files in my xxx_ejb.jar file. The third party jar file contains classes that are accessed by some custom classes which are in turn accessed by my bean classes. I get the following error when my custom classes attempt to use any of the classes in one of the third party jar files:
java.lang.NoClassDefFoundError: com/Ostermiller/util/CSVParser
Shouldn't I be able to access classes in jar files that are packaged with my xxx_ejb.jar file? I see the xxx_ejb.jar file as a resource of the application classloader that contains it but I don't see the third party jar files.

As per the Java EE specification, additional JAR files should be packaged on the EAR level. Only WAR files' WEB-INF/lib folder is scanned for JAR files to be added to the classloader.

Main class in a Jar File

Hi
I have created a ja file containing my whole project.
the jar file contains a java class which contains a main method.
now i want to run this java class present in my jar file from the command prompt. is it possible to do it. can we run a java file which is inside the jar file.
i don't want to extract the jar file to run the java class.
Please let me know what needs to be done in this case.
Thanks & Regards
Vikeng

now i want to run this java class present in my jar
file from the command prompt. is it possible to do
it. can we run a java file which is inside the jar
file.
java -jar MyJar.jarYou need to set the Main-Class attribute in the manifest, though.

How to run jar files with arguments?

Hi everybody,
Is it possible to run a jar file with arguments passed to its MAIN class?
If yes can you help me on how to do it?
Thanx

I am in complete agreement with FahleE. I'll refine it a bit.
On my machine (running RedHatLinux8.0) you can run the demos like this.
1. open a console window
2. go to the directory where the demo you wish to run, say, demo.jar, is located
for instance for the SwingSet2-demo
cd /usr/lib/java/demo/jfc/SwingSet2
3. run the jar file
java -jar demo.jar
In order to run it windows style, ie, launching by double clicking, save these lines in a file called
LaunchJar.sh
cd /usr/lib/java/demo/jfc/SwingSet2
java -jar demo.jar
where demo.jar is the jar file you want to run.
Right click on the LaunchJar.sh and go to the 'Properties' tab. Check the 'Execute' permissions for Owner/groups/others. You can also do the same thing by chmod command.
Now double-click on the LaunchJar.sh file: your application should be launched.
Palash.
Please Note: It is important to set the path variable to your JAVA_HOME directory....
Otherwise, instead of
java -jar demo.jar, you will need to use the full path to your JAVA_HOME/bin directory like:
JAVA_HOME/bin /java -jar demo.jar.
Where JAVA_HOME is the directory where you have installed java. Typically it is usr/java or usr/local/java

But I am unable to find out that portal runtime link in portal.
Please let me know. I have to finish this issue.

Hi,
Could you give us a few more details. What version of WLS are U using and if you could turn on -verbose on the ant command
and post the results.
Thanks,
Bruce
