[JBoss Portal] - How to get a portlet's instance name from the portlet class?

by porcho

Hi there. I was wondering whether it's possible to obtain the portlet's instance name from the portet class. More specifically, I wanted to do something like that: | public class APortlet extends GenericPortlet{ | | ... | | public void init() throws PortletException{ | String instanceName = this.something.getPortletInstanceName() | | ... | | } | So...is there a way to do it? Thanks in advance!

[JBoss Messaging] - Re: Problem with JEMS JMS install: User is NOT authenticated

by twenckebach

Hello, the JEMS installer has a bug, already in version JEMSInstaller_1_2_1_CR3_trunk. The login-config is incorrect: | <application-policy name = "messaging"> | <authentication> | <login-module code = "org.jboss.security.auth.spi.UsersRolesLoginModule" | flag = "required" > | <module-option name = "unauthenticatedIdentity">guest</module-option> | <module-option name = "usersProperties">messaging-users.properties</module-option> | <module-option name = "rolesProperties">messaging-roles.properties</module-option> | </login-module> | </authentication> | </application-policy> | The path to usersProperties and rolesProperties is wrong, it must be props/messaging-users.properties and props/messaging-roles.properties, respectively.

"adrian(a)jboss.org" wrote : As I commented on the "bug" report. This is not JMS, this is EJB3. | | OFF TOPIC - use the ejb3 forum rather than respond to this post. | | It isn't clear to me what you are doing, but it doesn't look like a bug to me. | It looks like you don't understand that ejbs are pooled and/or that multiple copies | of an entity bean can exist simultanously, | e.g. for optimisitic locking | | To have singletons you need to use some form of pessimistic locking which is usually not | very performant. Hi Adrian, Apologies for posting on the wrong forum, but the issue seems to present itself only in MDBs, therefore my assumption that it was an MDB problem. I didn't write the code, so you might be right. I think my understanding of pooling is pretty good, ergo the post and the "Bug" in the title. I'm pretty sure this is broken: After making 351 requests, how many instances of RecordManagerBean do you think were created? The answer is, 351. postConstruct was called 351 times and preDestroy was called 0 times, so none of these instances were claimed back. Is there a fault in my understanding of how this should work? What happened on the 352'nd request? Here: Can't create thread: 5 | 13:34:45,519 ERROR [JmsServerSession] Unable to schedule work | javax.resource.spi.work.WorkRejectedException: org.jboss.util.threadpool.ThreadPoolFullException: java.lang.OutOfMemoryError: unable to create new native thread | at org.jboss.resource.work.WorkWrapper.rejected(WorkWrapper.java:250) | ... | JBoss is started with -Xms128m -Xmx512m, so maybe these memory settings will make it easier to replicate the bug. Here is also a script to call the calculator injection mdb 3 times every second: URL="http://<YOURIP>:8080/EJB3Trail/serviceobjects/injection/calculator.jsp?action=send&start=25&end=65&growthrate=0.08&saving=300&submit=Calculate" | | out=/dev/null | content=/dev/null | | i=0 | while [ $i -ne 500 ]; do | i=`echo "1 + $i" | bc -q` | echo $i | wget $URL --output-file $out --output-document $content | wget $URL --output-file $out --output-document $content | wget $URL --output-file $out --output-document $content | sleep 1 | done Please be so kind to ponder on my comments and reconsider whether it still looks like I don't understand ejb's and pooling. Also consider that jaikiran independently verified this with his own code. Also consider the fact that this behaviour does not occur if we do not use MDB, i.e. just by using stateless beans.

[Beginners Corner] - Re: A can't see the jmx-console

by hudson.paula

Thanks jaikiran. But now, you make me a little scared. When I insert the "-b 0.0.0.0" in the start of JBossAS 4.2.2.GA a was can access the jmx-console like you said. Then I did another test. I put a application ".war" which was running in the 4.0.2 version in the new version and when I did start the "THE APPLICATION DON'T WORKS". Then I put the "-b ..." and so the application works. My Company is publishing the server in the internet and we do not knows!!! Do You know some literature where I can get the knowledge to fix this problem?

[EJB 3.0] - Re: EJB 3.0 Entity problem - Error: Incomplete Deployment li

by jaikiran

anonymous wrote : @PersistenceContext (unitName="tps") | protected EntityManager em; Also, as you mention that the persistence.xml is in the same jar (tps-entity.jar) as the EJB, change the above piece of injection code to @PersistenceContext | protected EntityManager em; | This should inject the persistence context of the default persistence unit (in this case the tps persistence unit). Let's see if that works.

[Beginners Corner] - Problems with JBPM BPEL Hello World example

by ami999

I am following the user guide of JBPM BPEL and trying to test the Hello World example. I have had no exceptions till step 5.3.3 After deploying the business process definition, I am trying to test it using the following: ant test I get the following error on the console: ------------------------------------------------------------------ (console) C:\Personal\BPM\bpel\jbpm-bpel-1.1.GA\examples\hello>ant test Buildfile: build.xml detect.wsdl: get.published.wsdl: check.mapping: generate.mapping: detect.mapping.tool: BUILD FAILED C:\Personal\BPM\bpel\jbpm-bpel-1.1.GA\examples\common\mapping-build.xml:148: The following error occurred while executing this line: C:\Personal\BPM\bpel\jbpm-bpel-1.1.GA\examples\common\mapping-build.xml:68: c:\dev\jboss-4.2.2.GA\client not found. ----------------------------------------------------------- The issue above seems to be the target directory. My Jboss install is in C:\Personal\jboss. For some reason it is thinking it should copy to C:\dev\jboss-4.2.2.GA Do I need to set JBOSS_HOME or some variable? Other steps worked fine so far.
