I'm having a problem with setting the classpath. I'm trying to use the SkinLookAndFeel thingy but for example if I use the
the compiler says "package not found". I've included the class path using the control panel like .;C:\Java\Skins\skinlf.jar but still its not working. However, it works if I put the *.jar files in the ext directory in the JDK../JRE folder. It also works if I include the path in the JDK profile of the compiler, but what if try to run it on another computer?
What am I doing wrong? Is it possible to set the class path in the code? I've read some articles where they describe running the program like java -classpath /java/MyClasses/myclasses.jar utility.myapp.app How will I get it to work if I create an exe using an installer to run my program?
Also, does any of you guys know of an installer(I hope a free one) that would automatically detect the Java Home folder and place the Skin files in the ext folder?
One possible solution to your problem is to pacakge your program as an executable JAR file. You need to include a manifest file in the JAR with Main-Class: and Classpath: attributes. This will make it so that the user can double-click on the JAR to run it, as long as the JVM is installed and configured correctly.
Is there any rules in how I include it in the manifest file? And this means that I have to create a jar file whenever I want to test it right? Also, whenever I double-click on my jar files, WinRar always opens it, even though I have dis-associated jar files from it I havent found a way to get around it yet.
Are you on Windows? It is possible to change the default open command by going into windows explorer, Tools | Folder Options | File types and scroll down to jar files. Edit that and you will get a list of commands, select one and click Set Default to change the default. You can add a new one if needed.

A manifest file is simply a text file that gets packaged into the JAR file in a particular way. You need to use the -m option in order to specify your own manifest file. If you are using the command-line, type "jar" without any options to see the syntax for adding a manifest file.
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
