[tcljava-user] evalFile & package require: How to execute a tcl file that starts a tcl based app?

[Richard S. <arc...@gm...>]

Hello,

I am trying to run a tcl script that then runs a tcl script application.
This is normally done by calling main.tcl and the wish84.exe in the Tcl
Interpreter /bin directory via a desktop shortcut. main.tcl then calls
another file which calls several more...

I am now attempting to perform a similar operation (running the app) by
calling main.tcl using evalFile. However when I run the program I get the
error:

"can't find package starkit".

I have tried placing the java file(s) which invoke this in several
directories, including the one where main.tcl is located and the 'start-in'
location pointed to in the desktop shortcut(s).

This is the main.tcl file:
=================
package require starkit
starkit::startup
package require app-start

==============

The callStapTk() java method:
====================
    public void callStapTk() {

        Interp callingStap = new Interp();
        try {
            callingStap.evalFile(defaultStapLoc); /* String defaultStapLoc =
"C:\\dissproject\\starkits\\staptk.vfs\\main.tcl"; */
            System.out.println("Running default StapTk...");

        } catch (TclException ex) {
            int code = ex.getCompletionCode();
            switch (code) {
                case TCL.ERROR:

                    System.err.println(callingStap.getResult().toString());
                    break;
                case TCL.BREAK:
                    System.err.println(
                            "invoked \"break\" outside of a loop");
                    break;
                case TCL.CONTINUE:
                    System.err.println(
                            "invoked \"continue\" outside of a loop");
                    break;
                default:
                    System.err.println(
                            "command returned bad error code: " + code);
                    break;
            }
        } finally {
            callingStap.dispose();
        }

    }

===================
The Desktop Shortcut properties:

Target Type: Application
Target location: bin
Target: C:\Tcl\bin\wish84.exe C:\dissproject\starkits\staptk.vfs\main.tcl
Start In: C:\dissproject\STAPTK-INSTALL

==================

This is the same file that is called in the shortcut, which has no problem
finding packages. Do I have to modify the evalFile call? The whole purpose
of this exercise is to remove the need for a seperate Tcl interpreter
installation by using the one within Jacl.

Any help, advice, code, much appreciated.

Hi,

Your error is that the starkit package is not found. This is part of the
vfs package, which is shipped with tcl8.4...

I dont know how ones uses tcl packages from jacl, as I'm a new tclblend
user..
but it seems you are currently sourcing tcl scripts (unwrapped), and not
starkits, which is what the starkit package is required for. You might
want to bypass this if you are not planning on using starkits.

nikos

I can only conclude that you are trying to run your Tcl application that 
loads the starkit package inside Jacl.
That is not going to work since Jacl does not include support for the 
starkit extension. You will need to
use Tcl Blend to load native C extensions inside the JVM.
