Just guessing...
when the problem ocures, did you try to search for a process using address 8007?
It seems like some one else is trying to use such an address, but cannot figure out who.


Maybe another instance of the same app?

I do set it to 2500 using the -WOPort command-line argument. I prefer using browser shortcuts all set with main and direct action URLs. I have been doing this for years without problem. The problem I have now had just started to occur since a few days. I wonder if it is related to Mac OS 10.2.6 update...

Note that the log complains about address 8007 being in use. This is the address passed to the -Xrunjdwp:transport argument. This seems to be related to jdb, but I don't why this just started to malfunction.

Are you assigning the WOPort manually??

Hi,

Recently, I started getting the following error when I try to debug a WO app: Project Builder freezes solid for a while, and then the following appears in the log:

Reading MacOSClassPath.txt ...
Launching Pantagruel.woa ...
java -XX:NewSize=2m -Xmx64m -Xms32m -DWORootDirectory="/System" -DWOLocalRootDirectory="" -DWOUserDirectory="/Users/serge/Documents/Informatique/Pantagruel/ build" -DWOEnvClassPath="" -DWOApplicationClass=Application -DWOPlatform=MacOS -Dcom.webobjects.pid=13995 -classpath WOBootstrap.jar com.webobjects._bootstrap.WOBootstrap -WOAutoOpenInBrowser NO -WOPort 2500

Local transport failed to init.

FATAL ERROR in native method: No transports initialized
The Debugger has exited due to signal 6 (SIGABRT).


This happens from time to time, but often enough to be ennoying (about 1 time out of 10). When it happens, I just launch the application again and it works. I don't know what does this error means, why this happens and what I can do to avoid it.

I am using WebObjects 5.2.1, Mac OS X 10.2.6 and Java 1.3.1. I have never upgraded the machine to Java 1.4.
