First of all thanks for your reply! Unfortunately I am still facing the same problem with the use of the jclDevice runtime (java.lang.NoClassDefFoundError: java.awt.Window) when including the jna.jar file. The thing is that jclDevice doesn't support java.awt and it's almost impossible to add that package in the classpath (at least for me - I have tried to add single java.awt classes and also the whole rt.jar file). Additionaly I tried your suggestion - building up a simulative jawa.awt package (parallel to my own package), though, that didn't work either. Has somebody experienced similar problems?

You can always stub out java.awt.Window with your own class. I believe others have used J9 successfully with only minor adjustments.
Patches are welcome to facilitate using JNA in the absence of AWT; currently I believe you'll get an UnsatisfiedLinkError on jawt only if you try to use any of the window ID access functionality.

Dear JNA developers,
I am using IBM Lotus Expeditor in order to implement eRCP applications for mobile devices (jclDevice). Right now I want to load a dll file with the help of jna. Unfortunately the VM integrated in IBM Lotus Expeditor is the J9 VM, which doesn’t support java packages like java.awt. Thus, when I try to run the application and add the jna.jar-file into the classpath I get the following error:

This is most likely due to the import of some java.awt classes in the com.sun.jna.Native class. (https://jna.dev.java.net/source/browse/jna/trunk/jnalib/src/com/sun/jna/Native.java?rev=755&view=markup)
Are those packages really essential for the realization of JNA? Is there a way to deal with such issues?
Thanks in advance, Hristo Novatchkov
