Sorry, but I can't see your problem. After creating the file test.java
with the contents above I did the following:
bash-2.03$ javac test.java
bash-2.03$ ls -l test*
-rw-r--r-- 1 krischan install 281 Aug 16 09:01 test.class
-rw-r--r-- 1 krischan install 78 Aug 16 09:01 test.java
bash-2.03$ CLASSPATH=. jaclsh
% package require java
1.3.0
% set t [java::new test]
java0x1
% set x [$t run]
10
% exit
bash-2.03$
So everything seems to work as you expected. It is *really* so easy
to interact from Tcl with your Java classes!
Note: If the method is declared static,
public static int run() {return 10;}
you can use the java::call method to invoke it:
bash-2.03$ CLASSPATH=. jaclsh
% package require java
1.3.0
% java::call test run
10
% exit
Hope this helps,
Krischan
