[JBoss Messaging] - Re: JBoss slowing down
by pratimkm
Clebert,
We did the stack trace and found out that the number of WorkerThread for the clients beyond a firewall are steadily increasing by 1 or 2 everyday.It's shwoing up on jconsole as WorkerThread#17[10.**.2*.1**:34128] or similar.When it's reaching about 30-35 it's bringing down the server on it's knees.I was trying to find out if we close the connections properly after each 30 mins refresh period that I mentioned in the first post. We found that the code is correct.
Just for curiosity I tried to find out what happens with standalone clients. So we made a simple standalone client(non-firewall) and connected to jboss and did a stack trace through jconsole while doing load testing. We found out that the worker threads remain even after the client disconnects. Is it normal ?

[JBossWS] - Resteasy, handling and logging of WebApplicationException
by jrinderle
Resteasy logs a stracktrace for all WebApplicationExceptions, which is not what I was expecting. My expectation was that Resteasy would catch this exception and return an appropriate response, but not log the exception. This creates a lot of output in the server logs.
* What is the most appropriate way to specify a response status? I could return Response but it seems cleaner to return a specific type and throw WebApplicationException for errors.
I created the following test case:
| @GET
| @Path("/status/{code}")
| public String getStatus(@PathParam("code") int statusCode) {
| throw new WebApplicationException(statusCode);
| }
|
No matter what code I specify, the exception stack trace is logged to STDERR and I get the JBossWeb default error page back (even if I modify the code to specify no content).
* This behavior caused me to question my understanding. Should I not specify a response status by throwing a WebApplicationException? Should I instead return Response or use a custom exception with an exception mapper? In a production environment I do not need to log a stack trace for 401, 404, etc.
* Is it possible to disable the default error page and return an empty response? I tried changing the test case to throw new WebApplicationException(Response.noContent().status(statusCode).build()); but I still get default error page.
* I was also surprised to see the exception logged to STDERR. The documentation says that Resteasy uses slf4j configured or log4j. Perhaps I have something configured incorrectly?
I have tested this behavior with Resteasy 1.0.2GA and 1.1RC2. I am running on JBoss 4.2.3.GA.
When I request this resource with /status/401, I get the following response (output is from curl).

[Installation, Configuration & DEPLOYMENT] - Re: Scheduler IllegalStateException while migrating jboss4 -
by radimchatkalahari
Registering is now ok, but I dive in another problem:
My PingService MBean (PingScheduler depends on it)
is not registered (deployed) by jboss 5.1.0
I Could not find it in jmx-console (in jboss 4.x that was ok)
- I even tried to follow MBean naming conventions by renaming IPingService to PingServiceMBean but without success..
Here is code of PingService:
@Service
| @Local(IPingService.class)
| @Remote(IPingService.class)
| @Management(IPingService.class)
| public class PingService implements IPingService {
| private static Log log = LogFactory.getLog(PingService.class);
| private static final String SERVICE_NAME = "PingService";
|
| @EJB(beanName = "PingEJB")
| private IPingEJB fPingEJB;
|
| public void create() throws Exception {
| log.info("Creating service " + SERVICE_NAME);
| }
|
| public void destroy() {
| log.info("Destroying service " + SERVICE_NAME);
| }
|
| public void start() throws Exception {
| log.info("Starting service " + SERVICE_NAME);
| }
|
| public void stop() {
| log.info("Stopping service " + SERVICE_NAME);
| }
|
| @TransactionAttribute(TransactionAttributeType.REQUIRED)
| public void ping() {
| fPingEJB.whoIsAlive();
| }
| }
thank you
Radim
