Running tclsh from a Java application should not be that hard.
Trouble is, the Java implementation from Sun is really full
of bugs under Windows. You could take a look at the Jacl
implementation of the exec command for Tcl. I have to warn
you, it is a bit scary!

Have you considered using Jacl? Jacl is a Tcl interp
written in 100% Java. Adding Jacl to your existing Java
application might be easier, you just add tcljava.jar
and jacl.jar to the CLASSPATH and then create a tcl.lang.Interp
object.
