Java - problemas de aplicaciones con JBuilder

hola a todos
tengo instalado el Borland JBuilder 3 pero tengo un problema, solo funcionan
después de compiladas las aplicaciones que son basadas en JDK puro, ni siquiera
funcionan los ejemplos que trae de SWING y otras cosas.
Hay algo que no he configurado?
gracias

Deploying a Java Application
Java applications can be deployed as archives or as compiled Java .class
files. If you have more than one class in your application, you will
benefit by putting your application in a Java archive (.jar) file. The
only step you have to complete in order to deploy your application is step
one - the remaining steps will help ensure you are able to easily
distribute your application to end-users.These are the steps for deploying
a Java application in a .jar file:

Step
Description

1. Create a Java archive (jar) file.
Use the Deployment Profile wizard to configure a .jar file for
deployment.

2. Run the application .jar file from the command line.
Deploy the .jar file in a local directory and test to see that all of the
necessary components have been included.

3. Create a deployment set.
Create a batch file that will set the classpath and run the Java
application. Create a shortcut with a custom icon to launch the
application. Create a ReadMe.txt file with installation instructions.
Optionally, put the deployment set into an archive to maintain the
directory structure and make it easy to copy the application to the
end-user´s file system.

4. Test the deployment package.
Copy the deployment package to a "clean" machine. If you have archived
the deployment set, extract the files. Run your Java application.


Con esto he consegido que a veces me funcione cosas que no son solo de JDK, pero creo que no es una solución definitiva, si conoces alguna solución mejor te agradecería que me la enviaras

lo que pasa es que el jdk no queda como si lo instalaras, para que los ejemplos con extrension JAR funciones debes asocialos a javaw.exe con el parametro -jar
