After update from jboss4.2.3 to jboss5.1.0 performance is very bad. We use EJB3 with SSB and JPA Entities. After a debugging/logging session i think the security is the problem. Following test: ###################################################################### @TransactionAttribute(TransactionAttributeType.REQUIRED) @SecurityDomain("EVIJET") @TransactionManagement(TransactionManagementType.CONTAINER) @PermitAll @Stateless public class TC2 implements TC2Local { /** * Default constructor. */ public TC2() { // TODO Auto-generated constructor stub } public String ping() { return "ping"; } } ###################################################################### @TransactionAttribute(TransactionAttributeType.REQUIRED) @TransactionManagement(TransactionManagementType.CONTAINER) @Stateless public class SSBNoSecurity implements SSBNoSecurityLocal, SSBNoSecurityRemote { @Resource private SessionContext ctx; /** * Default constructor. */ public SSBNoSecurity() { // TODO Auto-generated constructor stub } public String ping() { return "ping"; } } ############################################################################# -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/530983#530983

[EJB 3.0] New message: "Re: howto setup jpa using oracle 10g unicode nvarchar2"

by jaikiran pai

User development, A new message was posted in the thread "howto setup jpa using oracle 10g unicode nvarchar2": http://community.jboss.org/message/530981#530981 Author : jaikiran pai Profile : http://community.jboss.org/people/jaikiran Message: -------------------------------------------------------------- A couple of other options you could try: 1) Try setting this in the -ds.xml: <connection-property name = "oracle.jdbc.defaultNChar">true</connection-property> I am not sure whether that will work (I have seen some other users complain that it doesn't work) 2) Pass the oracle.jdbc.defaultNChar as a Java System property through your run.conf (or run.bat for Windows) -Doracle.jdbc.defaultNChar=true Add that to the JAVA_OPTS section P.S: Make sure that you are using the correct Oracle JDBC driver version. From what found in a google search, Oracle 10 driver is required for this property to be recognized. -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/530981#530981

[jBPM] New message: "Re: jBPM 4.3 and business rules/Drools integration"

by Maciej Swiderski

User development, A new message was posted in the thread "jBPM 4.3 and business rules/Drools integration": http://community.jboss.org/message/530975#530975 Author : Maciej Swiderski Profile : http://community.jboss.org/people/swiderski.maciej Message: -------------------------------------------------------------- In my opinion jBPM will create KnowledgeBase based on the resources that are deployed to database regardless of how they were packaged.Resources are kept in db as separate instances (class, xml, drl, etc) not as whole package (bar). So if you deploy your process definition (with all its resources - classes, rules, etc), let's called it manually (using repositoryService) jBPM will create KnowledgeBase based on resources retrieved from data base for the process definition. -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/530975#530975

[EJB 3.0 Development] New message: "Re: Lookup to java:comp/EJBContext during postconstruction"

by jaikiran pai

User development, A new message was posted in the thread "Lookup to java:comp/EJBContext during postconstruction": http://community.jboss.org/message/530970#530970 Author : jaikiran pai Profile : http://community.jboss.org/people/jaikiran Message: -------------------------------------------------------------- > jaikiran wrote: > And i don't think it's specific to the EJBContext. I guess it will fail for anything under java:comp for that bean. Can you give a quick try by looking up something else under java:comp from within the @Postconstruct of MDB? Looked at that stacktrace again and it indeed appears to be specific to java:comp/EJBContext Caused by: java.lang.NullPointerException at org.jboss.ejb3.EJBContextFactory.getObjectInstance(EJBContextFactory.java:57) at javax.naming.spi.NamingManager.getObjectInstance(NamingManager.java:304) at org.jnp.interfaces.NamingContext.getObjectInstance(NamingContext.java:1483) at org.jnp.interfaces.NamingContext.getObjectInstanceWrapFailure(NamingContext.java:1500) It appears that the AbstractPool invokes the postconstruct after popping the context from the thread local stack: protected BeanContext<?> create(Class[] initTypes, Object[] initValues) { BeanContext ctx; ctx = createBeanContext(); container.pushContext(ctx); try { container.injectBeanContext(ctx); ctx.initialiseInterceptorInstances(); } finally { container.popContext(); } container.invokePostConstruct(ctx, initValues); // the init method only applies to stateful session beans ++createCount; return ctx; } The fix looks simple enough. I'll file a JIRA for this. -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/530970#530970

There is even Tomcat integration package that provides some authentication mechanism to be able to connect to jBPM tables - they are slightly different than Tomcat JDBC realm configuration assumes.

You can try different configuration for HistoryProcessInstanceQuery as well if above example does not suit your needs.

[jBPM] New message: "Re: Generate Image from ProcessDefinition"

by Sriraman Gopalan

User development, A new message was posted in the thread "Generate Image from ProcessDefinition": http://community.jboss.org/message/530961#530961 Author : Sriraman Gopalan Profile : http://community.jboss.org/people/sreeraaman Message: -------------------------------------------------------------- Hi All, I am not sure if this is what you are looking at. Assuming that you designed the process using the GPD eclipse plugin, after deployment of the process (.par archive), you can get the image of the process as a byte[] as shown below: public byte[] getProcessDiagram(Long processDefinitionId) { byte[] returnValue = null; JbpmContext context = getJbpmContext(); try{ GraphSession graphSession = context.getGraphSession(); ProcessDefinition processDefinition = graphSession.getProcessDefinition(processDefinitionId); FileDefinition fileDefinition = processDefinition.getFileDefinition(); returnValue = fileDefinition.getBytes("processimage.jpg"); } catch(Exception e){ e.printStackTrace(); } finally{ context.close(); } return returnValue; } Form the returning byte[] you can manipulate the image as desired. This is as of JBPM 3.2.3. -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/530961#530961
