[tcljava-user] TclBlend - how to debug?

[Patrick F. <fin...@gm...>]

I get a Null point exception when I try to instanciate an imported class.
What's the best way to debug Blend?

Using TclBlend Windows binary.

C:\TclBlend\bin>jtclsh

% set derbyLib [ file join $env(DERBYHOME) lib ]
C:/db-derby-10.2.2.0/lib

% set env(TCL_CLASSPATH) $derbyLib
C:/db-derby-10.2.2.0/lib

% package require java
1.4.0

% java::import java.net.InetAddress

% java::import org.apache.derby.drda.NetworkServerControl

# display imported classes.
% java::import
org.apache.derby.drda.NetworkServerControl java.net.InetAddress

% java::new NetworkServerControl
java.lang.NullPointerException

The script works when started from a bat file with the jars are added to the
system classpath .


::set CLASSPATH=%CLASSPATH%;C:\db-derby-10.2.2.0\lib\derby.jar
::set CLASSPATH=%CLASSPATH%;C:\db-derby-10.2.2.0\lib\derbyclient.jar
::set CLASSPATH=%CLASSPATH%;C:\db-derby-10.2.2.0\lib\derbynet.jar
::set CLASSPATH=%CLASSPATH%;C:\db-derby-10.2.2.0\lib\derbytools.jar

C:\TclBlend\bin\jtclsh.exe C:\startNetworkServer.tcl
