had a look on the existing javaadmin script.
It shouldn´t be a big deal to modify it thus we could implement it to the core files.
Alll PHP files are copyright by Stephan (maybe we could get the rights).
Would be better to rewrite the whole Script based on such a free library (with support, bugfixes and a big community). The second proposal would need some time and may not be finished until WB2.7 becomes available.
