[tcljava-dev] TclBlend Core Dump

[Bruce C. <bru...@ya...>]

Thank you for your response and willingness to help.

I have this problem in a very small box. 

Behavior:

When making a Tcl "package" and a command extension using an outside SNMP implementation, the command causes a core dump. The same implementation in JACL works fine. I reduced the problem to a few dependencies in the Java made package. They are:

Use the package command in Java

Throw an exception



Files:

Filename: PTLCommands.java

import tcl.lang.*; 

public class PTLCommands extends Extension {

public void init(Interp interp) {

interp.createCommand("sayhello", new SayhelloCmd());

}

}

Filename: SayhelloCmd.java

import tcl.lang.*;

import snmp.*;

class SayhelloCmd implements Command {

public void cmdProc(Interp interp, TclObject argv[]) {

try {

SNMPsample comInterface = new SNMPsample();

}

catch(Exception e) {

}

}

}

Filename: SNMPsample.java

package snmp;

import java.net.*;

public class SNMPsample {

public SNMPsample() 

throws SocketException {

}

}

Filename: a.tcl

package require java

java::load -classpath . PTLCommands

Steps:

Get to the tclsh prompt

%source a.tcl

%exit

A core dump is produced. I suspect that the Tcl package command and the Java package command are conflicting. I am under the impression that the TclBlend environment allows for Java and tcl commands to co-exist.
