I tried this. I had a bit of fun getting the daily build to build - I'm
assuming you do this from build in the all directory?
I had to drop log4j out of logger, move cli and instrument to under all, use
the latest development jars for logkit and framework etc, blah blah
Eventually got it to compile, put all the jars into cocoon, rebuilt that ...
Start tomcat, which complains about not being able to start cocoon logger
Now it works EVERY ALTERNATE TIME ?? I run the xsp/esql example
First time it works.
Hit refresh and it fails with
Original exception : java.lang.RuntimeException: Could not get the
datasource

and I can see the port connections getting dropped
Hit refresh and it works again.
Hit refresh and it fails again as above.
Eventually, I get nothing back at all
:-{
Is this just me?
If not, is it something that could be fixed soon, or would you advise me to
go back to jdk1.3 for the while ??
