[Performance Tuning] New message: "Re: CPU usage increases daily for JBoss PID, reaches to 100% after 10 days."

by Peter Johnson

User development, A new message was posted in the thread "CPU usage increases daily for JBoss PID, reaches to 100% after 10 days.": http://community.jboss.org/message/519005#519005 Author : Peter Johnson Profile : http://community.jboss.org/people/peterj Message: -------------------------------------------------------------- {quote}I doubt that Hashmap is corrupted. the reason is, we are using struts2,{quote} I would be very leery of this statement. Last summer I worked with a customer who was running into stack overflow issues. Turns out they were using a well know open source library (I'll call it lib1) which in turn used another open source library (I'll call it lib2) incorrectly. It turns out that lib2 is not thread safe, yet lib1 was spanning multiple threads, each one using lib2. Issues like this rarely come out during development testing because that is usually single threaded. Not until load testing, or worse in production, when multiple threads are being run do such problems show up. -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/519005#519005

by Gorkem Turan

User development, A new message was posted in the thread "JBoss 5.0.1 for jdk 1.6 web services configuration": http://community.jboss.org/message/519004#519004 Author : Gorkem Turan Profile : http://community.jboss.org/people/gturan@acm-software.com Message: -------------------------------------------------------------- Saaj.jar file comes with jboss 5.x. That is under jboss->lib->endorsed . In some forms I saw addinglines to jboss launch config; -Djava.endorsed.dirs=$JBOSS_HOME_5/lib/endorsed -Dsun.lang.ClassLoader.allowArraySyntax=true Which did not help. I changed jboss 5.0.1 jdk to 5.1.0 jdk also did not help. The file I try calling the service is below. (and the amazon web service jar file is under the WEB-INF->lib of the project folder.) import java.util.List; import javax.xml.ws.Holder; import javax.xml.ws.WebServiceRef; import com.corejsf.amazon.AWSECommerceService; import com.corejsf.amazon.AWSECommerceServicePortType; import com.corejsf.amazon.Item; import com.corejsf.amazon.ItemSearchRequest; import com.corejsf.amazon.Items; public class AuthorSearchBean { @WebServiceRef(wsdlLocation ="http://webservices.amazon.com/AWSECommerceService/AWSECommerceService.wsdl") private AWSECommerceService service; private String name; private List<Item> response; private String accessKey; public String getName() { return name; } public void setName(String newValue) { name = newValue; } public void setAccessKey(String newValue) { accessKey = newValue; } public String search() { try { AWSECommerceServicePortType port = service.getAWSECommerceServicePort(); ItemSearchRequest request = new ItemSearchRequest(); request.getResponseGroup().add("ItemAttributes"); request.setSearchIndex("Books"); request.setAuthor(name); Holder<List<Items>> responseHolder = new Holder<List<Items>>(); port.itemSearch("", accessKey, "", "", "", "", request, null, null, responseHolder); response=responseHolder.value.get(0).getItem(); return "success"; } catch(Exception e) { e.printStackTrace(); return "failure"; } } public List<Item> getResponse() { return response; } } Actually this is web service demo application I got from http://horstmann.com/corejsf/ Under source code ch10->amazon is what I am trying to run. Thanks for the reply. -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/519004#519004

[jBPM] New message: "Re: How to terminate a forked process"

by Jas Lam

User development, A new message was posted in the thread "How to terminate a forked process": http://community.jboss.org/message/519000#519000 Author : Jas Lam Profile : http://community.jboss.org/people/lamj1 Message: -------------------------------------------------------------- In fact, my code is somewhat irrelevant. It is more like how to terminate a forked process while it is still active? without causing exception and ensure the database entities are cleaned up gracefully. Junit code: public void testForking() { ProcessInstance processInstance = workflowManager.startProcess("ForkSubProcess"); String pid = processInstance.getId(); //sleep to allow fork to create task before querying it try {Thread.sleep(2000);} catch(Exception e){} //verify that there are two outstanding tasks assign to testUser List<Task> taskList = taskService.findPersonalTasks("testUser"); assertEquals(2, taskList.size()); //attempt to ends all processes, while they are still active workflowManager.endAll(); } public void endAll() { ProcessInstanceQuery query = executionService.createProcessInstanceQuery(); List<ProcessInstance> listPI = query.list(); for(ProcessInstance processInstance : listPI) { //using execution service to end //1. cause a child record found error - if this is the parent process //2. cause a null pointer exception - if this is the forked process // For the second case, I traced the code and found out that endProcessInstance method // query for the processInstanceid with a where clause parents == null // <query name="findProcessInstanceById"> // <![CDATA[ // select processInstance // from org.jbpm.pvm.internal.model.ExecutionImpl as processInstance // where processInstance.id = :processInstanceId // and processInstance.parent is null // and processInstance.state != 'suspended' // ]]> // </query> executionService.endProcessInstance(processInstance.getId(), "active"); //OR //i also tried this - unit test quit after this. Nothing was done ((ExecutionImpl) processInstance).end(); } } -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/519000#519000

So: myapp.ear | |--- META-INF | | | |--- persistence.xml And let the persistence.xml use the "jar-file" element to point to the jars containing the entities. This is how the EJB3 persistence spec lets EAR level persistence.xml to be deployed.
