Some libraries don't work when running JNLP fi

问题:

Everything works in my Java EE project when I'm running it from Netbeans, but when I deploy it in Glassfish server and run downloaded JNLP file, some added libraries don't work.

Any ideas?

Any library that your program needs that is not part of the standard Java SE distribution must be referenced in the JNLP file. Part of your JNLP file might be:

<resources>
   <j2se version="1.6+"/>
   <jar href="serdarsProject.jar" main="true"/>
   <jar href="lib/activation.jar"/>
   <jar href="lib/mail.jar"/>
   <jar href="lib/jcommon-1.0.16.jar"/>
   <jar href="lib/log4j-1.2.jar"/>
</resources>

Since mail.jar and activation.jar are included with Java EE, you would not need these in your library when running a Java EE project in netbeans.

Turn on the Java Console in your preferences. In Windows, you can do this through the Control Panel - the option is found in the Java Control Panel. When some function in your program fails to work, you will probably see a specific error message in the output window. This might help you determine which jar libraries you need to include.
