Debug session with eclipse in Linux

Disclaimer: I am not an expert with wine nor have I ever claimed to be. But if you setup an override for the msxml dll it seems as though the BlackBerry simulator is a bit more reliable in Linux. In fact, the JDWP seems to actually work for debugging your applications.

This was actually pretty trivial since the MDS simulator is pure Java, and a good portion of it is actually just Tomcat. Since Tomcat is not developed by RIM, the chances where pretty good that there where no hard coded backslash directory separators (no, I will never let that go)

MDS simulator log output

All you have to do is create a new script to replace the various batch files that ship with the MDS simulator. Here is the replacement for run.bat

#!/bin/bash
 
for i in classpath/* webserver/lib/*; do
  MDS_CP=$i:${MDS_CP}
done
 
java -classpath ${MDS_CP} -Xmx512M -DKeystore.Password=password \
   net.rim.application.ipproxyservice.IPProxyServiceApplication \
   -log.console.dump

Don’t forget to set the execute permission:
chmod +x run.sh

To shutdown MDS, just hit <ctrl>+c in the terminal window to kill the process.

Being obsessive and all, I decided to sit down and figure out why the signature tool doesn’t seem to work in Linux. After all it’s a rather trivial Java application. I suspected from the start that the symptom was some sloppy programming on RIM’s part, hard coding Windows style path names and my suspicion was correct. After modifying two class files and reassembling SignatureTool.jar the signature tool worked like a charm!

I don’t know what the legality is regarding redistribution of RIM’s development tools, specifically ones that have been modified so what follows is a description of the steps required to modify SignatureTool.jar to work in a Unix style file system (forward slash for directory separators).
