J-Link debugging

Have you tried http://www.eclipse.org/?

I use NetBeans for my IDE. You can attach a debugger to your appliction in sync mode.

Here is the config.pro option to attach a debugger.

jlink_java_command C:\proapps\proeWildfire_4.0\x86e_win64\obj\JRE\bin\java.exe -Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=n

Then in Netbeans you go to Debug - Attach Debugger

I'm assuming you can probably do the same in Eclipse as well.

Apart from using a debugger, I sometime write to the system.out stream when catching exceptions in a J-Link program.

Because you do not have acces to system.out from the console, the method I used is changing the Pro/E startup command to:

%PROE_LOADPOINT%/proe.exe > C:\temp\output.txt

(On Microsoft Windows)

Everytime you write to the system.out stream from within your jlink application, this is written to the output.txt file.

This can be useful for performing some quick logging.

Debugging a Synchronous JLink Application using Eclipse

Description:

This document explains how to attach the debugger to a synchronous application using the Eclipse EE.

Setting the Config.pro Option

First you will need to set the config.pro option named “jlink_java_command” to point to the Pro/ENGINEER Wildfire version java.exe in the config.pro file. The option value is shown below.

For 32 Bit Systems:

jlink_java_command

C:\ptc\proeWildfire5\i486_nt\obj\JRE\bin\java.exe –Xdebug –Xnoagent

-Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=n

For 64 Bit Systems:

jlink_java_command

C:\ptc\proeWildfire5\ x86e_win64\obj\JRE\bin\java.exe -Xdebug

-Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=n

Note:

It is best to edit the config.pro file inside a Pro/ENGINEER session.

Setting an Eclipse Debug Configuration

You will need to setup a “Remote Java Application” debugger configuration in the Eclipse environment in order to attach the JLink synchronous application.

Select the debug icon > Debug Configurations in the Eclipse IDE Toolbar.

Double click on the Remote Java Application > Select Project > Select Apply.

Make sure that the Port number is the same as listed in the config.pro option.

Start Pro/ENGINEER with the protk.dat file registered. Select the Debug button for the Remote Java Application. The synchronous application must be running first before the Remote Java Application is executed otherwise Eclipse will throw an error. Once the Remote Java Application is running then you should see the remote connection icon in the debug tab, as shown below.

The last step is to execute the Synchronous Application in the Pro/ENGINEER session. You will see that it will go to the first break point in the Eclipse IDE.

You have several options:

1. remote debugger (explained in @jkent reply)

2. use System.out.println() and setOut() to file - this will setOut for all jlink applications

3. use Logging framework eg http://logback.qos.ch/ .. note you have to put classpath dir to protk.dat classpath of logconfig file
