Re: remote debugging -- JAVA400-L

Their currently exist two methods for debugging Java on the iSeries, one
which is done locally on the 400, one which is done remotely from a Windows
32-bit PC:
   iSeries system debugger
   IBM DIstributed Debugger

For the iSeries system debugger, if you do to
http://publib.boulder.ibm.com/pubs/html/as400/v4r5/ic2924/index.htm and
then expand (left-hand frame) Programming->Java->AS/400 Developer Kit for
Java->Debugging, you will find information about using the system debugger
to debug Java. Two methods of debugging exist: debugging a standalone Java
program, and debugging Java code running in another process (such as a
server). I quickly read through some of the information, and it may not be
as detailed as you would like, but it should get you started. Note also
that the information on debugging servlets is out of date.

For the IBM Distributed Debugger, it is available with Visual Age for Java
and also with the WebSphere Development Studio for iSeries
(http://www-3.ibm.com/software/ad/wds400/). Don't let the WebSphere part of
the name mislead you - these tools are for more than just WebSphere
development. The distributed debugger is installed on your PC and provides
a GUI for remotely debugging your code running on the 400. This debugger
supports debugging many different languages (RPG, COBOL, C/C++, Java, etc)
as does the system debugger. The distributed debugger also allows to debug
a standalone Java program or Java code running in another process.  The
documentation that comes with the debugger includes speicfics on how to
debug on the 400 (the distributed debugger allows debugging on non-iSeries
platforms as well).

Then the preferred way to debug programs running on the iSeries is STRDBG,
right?  A brief description of how to use STRDBG against Java classes or a
pointer to some specific information would be very helpful to those of us
whose primary focus is not the AS/400.
