RE: Debugging remote 1.4.2 jvm
I assume attach mode is further down the road, for either jdb or Jdebug mode? One question about functionality: In either debugger, is it possible now, or expected, that if you get to a point where you're viewing the value of a ByteArrayOutputStream, to be able to dynamically view the contents as String (essentially view new String(baos.toByteArray()))? -Original Message- From: Paul Kinnucan [mailto:[EMAIL PROTECTED] Sent: Thursday, December 02, 2004 10:15 AM To: Karr, David Cc: [EMAIL PROTECTED] Subject: Debugging remote 1.4.2 jvm Karr, David writes: I've decided to try experimenting with the jde debugger to see if it has features that make it worth using over netbeans.

I'm not. I'm only going to be remotely connecting, so it appears that I wouldn't set that variable. I set the Server Socket variable to the JPDA port my debuggee is configured for. The customize info for this variable seems ambiguous whether this is the correct variable to set. At this point, the contents of the Attach Process menu is grayed out, so I can't select a server to connect to.

JDEE version: 2.3.4 XEmacs version: 21.4 (patch 13) Rational FORTRAN [Lucid] (i586-pc-win32) of Sun May 25 2003. Windows version: Windows XP Here are the steps I used: 1. Set jde-sourcepath for my project to ./src 2. Set jde-run-option-debug as follows: Jde Run Option Debug: * [Value Menu] Connect: Mode: [Value Menu] Server Data Transport: [Value Menu] Shared Memory Shared Memory Name: [Value Menu] javadebug Socket Host: [Value Menu] nil Socket Port: [Value Menu] Suspend?: [Value Menu] No 3. Put point on the line where I wanted to set a breakpoint and selected Toggle Breakpoint from the Jdb menu. The JDEE highlighted the line in red. 4. Pressed C-c C-v C-r to run my program. My program ran to the point where it prompted me for input in the run buffer in Emacs. 5. Opened a new frame on the source buffer for the program. 6. Selected External Process-Attach Via Shared Memory from the buffer's Jdb menu. The JDEE started jdb and passed the breakpoint to it. Jdb responded with the following messages in the jdb buffer. Initializing jdb ... stop at jmath.Test:27 Set breakpoint jmath.Test:27 The breakpoint turns red to signify that it is enabled. 7. I selected Continue from the Jdb menu. Jdb responds: cont Nothing suspended. 7. I switched to my program's run buffer and entered some text and hit return. The debugger runs my program to the breakpoint and pauses. Breakpoint hit: thread=main, jmath.Test.main(), line=27 bci=163 27LinearSystem s = new LinearSystem(A); 8. I displayed the value of a local variable by entering a print command in the jdb buffer: main[1] print B[1] B[1] = 5.0 I then stepped a few lines and selected Continue from the Jdb menu to run the program to completion.
