I can't figure out how to debug a Webstart application. Here are the steps I go through:
1) Compile ToolTipListenerTest.java
2) Create a jar file using the following command:
jar cfev ToolTipListener.jar ToolTipListenerTest ToolTipListener*.class
3) Test the jar file using:
java -jar ToolTipListener.jar
Click on one of the listener radio buttons and 3 JOptionPanes will appear. This is good.
4) Try to test using a .jnlp file:
javaws ToolTipListener.jnlp
Click on one of the listener radio buttons and only 1 JOptionPane appears. This is bad as I expect 3 to appear like above test. I can't figure out what is happening or how to further debug the code. Any hints.
