I assure you it does, for examples using jedit, freeplane, rssowl.

Because it wants to install extra java software and I have already
java installed.

That does not work:

JAVA_HOME=/usr/local/java/java /usr/local/scilab/scilab/bin/scilab

Could not load JVM dynamic library (libjava).
Error: libjvm.so: cannot open shared object file: No such file or directory
If you are using a binary version of Scilab, please report a bug
http://bugzilla.scilab.org/.
If you are using a self-built version of Scilab, update the script
bin/scilab to provide the path to the JVM.
The problem might be related to SELinux. Try to deactivate it.

Scilab cannot open JVM library.
