Re: [tcljava-user] Executing tcl script from java using Interp,need help about classpath

[Ying J. <yi...@as...>]

Thank you very much!
I added tcljava.jar and tclblend.jar to my CLASSPATH, but I got the SAME error message. Could you give me further advise? Thanks a lot.
I got the SAME error message when I ran this java code inside tcl (After I type nmake shell). But I can successfully run other commands like "puts "say hello" " inside tcl. I also can create my own extension command.
The only problem is how to invoke tcl script by java code.
My code stop at new Interp(). Inside the constructor of Interp.java, the code stop at "interpPtr=create( ) ;".
Thanks a lot.
