Re: No transports initialized error when debugging

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:

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.
