Unfortunately, I am also one of the poor souls who are forced to work with native libraries. (In my case the authentication libraries of CentraSite.) Native libraries are generally a pain and one of the devils more successful inventions. In the case of the Tomcat plugin they have prevented me from using it for quite some time. Instead I was typically starting Tomcat from a shell script: The shell script has been setting the necessary environment variables like PATH under Windows or LD_LIBRARY_PATH under Linux/Unix, which indicate the location of shared libraries aka DLL's.
I wondered for some time, whether it wouldn't be quite easy to add support for setting these variables to the plugin. At some point, I contacted the plugins author and asked for the sources in order to add the missing feature myself. He never responded. However, recently I found that he did something much better: If you open the plugins zip file, then you'll notice, that it contains a file called tomcatsrc.zip. Yes, these are the plugins sources. And, even better, there also is a file called license.txt, which tells you that the plugin is licensed under the MIT license, a very liberal license, that allows me to change the sources. I could even distribute an updated plugin.
It turned out, that the work was even quite easy. Adding a control to the preferences page, some resource strings and a piece of configuration to an Eclipse configuration object for launching external programs, that's basically it.
If you're interested, I'll post the patch below. Let's hope, that this patch, which I have submitted to the plugins author will appear in the next version.
