Hi Chunk,


Chuck. Please.

I am new to webobject environment and have to make it working for one project in Mac OS Xserver 10.5.6. The version of the webobject is 5.4.3. The database server is mysql in another server- linux. The mysql connection is working fine between Mac and linux. The application has been configured and started using Java Monitor without problem. But when I try to connect to the application (http://......./cgi-bin/WebObjects/..... ) it produce “An Internal Server Error...”.

That means your application threw an exception.


The application log shows the exception below and the wotaskd log keep “waiting for request....”. The netsta showing the following:

 t2gtestnz:~ sysas$ netstat -an | grep 1085

tcp4 0 0 10.50.6.18.1085 10.50.6.18.49517 ESTABLISHED

tcp4 0 0 10.50.6.18.49517 10.50.6.18.1085 ESTABLISHED

tcp4 0 0 10.50.6.18.1085 10.50.6.18.49537 TIME_WAIT

udp4       0      0  *.1085                 *.*

I checked your group and there might be similar problem in the archive, but there was not exactly the same problem although it was useful to check some configuration which was fine in my case.

The Exception:

[2009-04-25 14:31:01 NZST] <WorkerThread1> <com.webobjects.appserver._private.WOComponentRequestHandler>: Exception occurred while handling request:

com.webobjects.foundation.NSForwardException [com.webobjects.jdbcadaptor.JDBCAdaptorException] null

[2009-04-25 14:31:01 NZST] <WorkerThread1> <WOWorkerThread id=1 socket=Socket[addr=/10.50.6.18,port=51504,localport=2001]> Exception occurred while responding to client: com.webobjects.foundation.NSForwardException [com.webobjects.jdbcadaptor.JDBCAdaptorException] null

I have no idea what that is. You will need to catch the exception (try in dispatchRequest) and drill down into the NSForwardException and log out the details.

ERXJDBCConnectionAnalyzer from Project Wonder might help you here.
