RE: Re: [tcljava-user] CLASSPATH using tclBlend

[Mike P. <mik...@ho...>]

I am sorry to be troubling you again but I have been unable to figure out h=
ow to set the CLASSPATH for my project so I can reference my JAVA classes f=
rom the tcl command line.  I have read the manual and 'start here' pages fr=
om the tcl/JAVA project homepages and have had no luck.  I have tried:
=20
% set CLASSPATH=3D%CLASSPATH%;C:/Project/Test3
=20
It is returning that it cannot read the variable.  There must be a CLASSPAT=
H variable though to set up all the other global variables so I am assuming=
 I am looking in the wrong place for the variable.
=20
I am based at the University of Manchester in my final year doing a softwar=
e engineering course so any help would be much appreciated.
=20
Thanks, Mike.  Ps- are you based at a University?

It sounds like you are using Windows, so you should be starting up
Tcl Blend via the jtclsh.bat script. It is installed in the bin directory
when you run "make install".

Open up the jtclsh.bat script in an editor and look for the lines where
the CLASSPATH is set. Copy the last set command and paste it on
a new line, then change the path so that it includes the root dir
where your Java classes live.

After starting Tcl Blend, you should be able to run:

package require java

If you were allocating a Java object named Test
in the package foo.bar, you would run:

set obj [java::new foo.bar.Test]

If you get this far, then your CLASSPATH is setup correctly. I hope that
fixes you problem. If it does not, then be sure to include the exact error
message that you are getting in your next post.
