com4j wrapper gen problems

Question

I am trying to generate wrapper for com4j using tlbimp-20110320.jar. I also tried a 2008 version with the same errors. I get the same errors even when I try running against the example in the tut.

e7\bin\java.exe" -jar tlbimp-20110320.jar -o excel -p excel "C:\Program Files (x

After Iceman provided a link to a required library I was able to get it to run a little. However I had to copy the arg4j contents into the tlbimp jar, and the com4j contents into the tlbimp jar as well. Now I get

tlbimp-20110320.jar is required args4j-2.0.1.jar and com4j-20110320.jar
Note: com4j-20110320.jar, it is necessary to change the name to com4j.jar

Additional Info

The tlbimp of the latest version (tlbimp-2.1.jar), requires args4j-2.0.8.jar and com4j-2.1.jar.
In this version, file name change is not required.

Unjar tlbimp.jar and check out its manifest. It has a classpath where args4j and com4j must be in the same directory as tlbimp.jar and require specific names. The specifics of the name depend on the build and may or may not include version number. Name your com4j and arg4j as indicated and you're good to go.

From the stack trace, it looks like you are missing dependent jars from the java class path. The program seems to be looking for Koshuke's args4j library - http://args4j.kohsuke.org/.

Ok. I downloaded the args4j-2.0.19.jar file, stuck it in /lib and the same error. I then tried it in the same directory and still the same error. – Mar 04 '12 at 05:52
Ok. I think I got it to work a little. I had to copy the args4j jar contents into the tlbimp jar. Then I got a different error which I could only resolve by doing the same with the com4j contents. It started to run for a bit before generating a NPE. – Mar 04 '12 at 05:56

Was there any progress on this since then? – monksy Aug 05 '14 at 21:39
