For me, the TDK Tomcat still won't run. I don't believe it is anything I'm doing.
My setup:
NT4.0 sp6a / JDK1.3 / TDK1.1a2 / Tomcat 3.2b4
In troubleshooting, I've done the following:
1) Install fresh JDK1.3 from Sun.
2) I stripped EVERY possible Classpath reference that could cause an out of date
jar file to be seen.
3) Removed all Turbine, TDK, ect local builds so that the TDK 1.1a2 won't get confused.
4) Downloaded and installed fresh TDK1.1a2
5) Set TDK1.1a2 as TOMCAT_HOME
6) execute: .\bin\startup
7) Tomcat seems to initialize properly
8) JDK-Tomcat won't serve any page (gives server contacted message waiting for
response)
alternatively:
9) Download fresh Tomcat 3.2b4
10) Set TOMCAT_HOME to it (reset environment)
11) execute .\bin\startup
12) Tomcat initializes
13) Serves pages nicely
In both scenarios I did the stack trace Gunnar suggested. The traces for each case
(TDK-Tomcat vs.
Regular-Tomcat)
are similar but had one noticable difference. Below is the trace for the TDK-Tomcat
case. Notice prior
to Thread-1
there are two "Standard Manager" daemons, each with separate task IDs.
The non-tdk Tomcat (which works properly) has FOUR of the StandardManagers daemons,
while the TDK
Tomcat has TWO. Is this significant ?
Why would they behave differently if they are from the same version of Tomcat. Was
Tomcat recompiled
specifically for
the TDK ?
Thanks for everyone's attention.
