Hi Eric,
These weird situations are sometimes best looked at by confirming what the
OS is seeing from user-space.
Can you run: sudo strace -r -f -e trace=network -p
You can then log that to a file and correlate and see if the kernel is in
fact being asked to send the response.
It's very
NoClassDefFoundError means that the class in question threw an exception
during its static initialisation phase. Then later on whenever some code
tries to access the class statically or create an instance the JVM will
throw a NoClassDefFoundError. This is not the same as a class not found

Hi Norbert,
The TCP socket states and timers are managed by the underlying OS and not
by Tomcat. Can you paste a netstat -an result so I can see what you mean.
Also, is the client using HTTP 1.1 with keep-alive or not? What kind of
traffic is this?

At runtime, any code can call TimeZone.setDefault to change the timezone of
the JVM.
I'd suggest logging TimeZone.getDefault().getDisplayName(Locale.ENGLISH);
intermittently and seeing if some code somewhere is changing the timezone.
Could be in any library...

I assume a servlet request is kicking off this process? If this is correct
then are you 100% sure that something is not calling the servlet more than
once? Perhaps a retry after a timeout or something?
Turn your access log on and look at what requests are coming in to the
server

Hi Anthony
Have you turned debug logging on to see what it is picking up as modified?

Can you not just put the jar in the /lib folder of tomcat

Please post a jstack of the pid 10 seconds apart. That will reveal all.

NoClassDefFoundError is not the same as ClassNotFoundException
Typically a NoClassDefFoundError is due to a class failing its static
initialisation when first loaded by the classloader. Can you check in your
logs for any prior errors (even at bootup) relating to class failing to be
loaded

Hi
I'm trying to design a Kafka consumer and producer that will run inside the
tomcat jvm and pick up messages off a Kafka topic and translate them into a
servlet request and pass it through tomcat and then when the response is
complete then translate it into a Kafka message and put it onto
16 matches
