[JBoss Seam] - JSF performance with increased facelets.BUFFER_SIZE

by mgrouch

I've been playing with performance related settings more and found one (a bit forgotten parameter) which made a big difference in my case. I've set this in my web.xml <context-param> | <param-name>facelets.BUFFER_SIZE</param-name> | <param-value>500000</param-value> | </context-param> | Increasing facelets.BUFFER_SIZE to 500000 cut JSF response time almost in half!!! This is for my case of rendering table see http://www.jboss.com/index.html?module=bb&op=viewtopic&t=117092 As far as I understand this buffer is short lived (only during response) so if there are not many concurrent request as same time increasing it would not create any memory consumption problems.

[JBoss Seam] - Re: Custom annotation scanner

by swd847

I might be prepared to work on it, as I have a use for it, but I would need confirmation on how people would want it to work. The JIRA issue seems to just be about making the Scanner class public, so it is possible to write custom scanners. I was thinking of re-using the seam scanner to reduce startup times. I was thinking the configuration would be something like: | <scannerconfig> | <annotations> | <annotation class="com.custom.Annotation" variable="customAnnotationList" /> | </annotations> | <files> | <file pattern="*.customdata.xml" variable="customFileList" /> | </files> | </scannerconfig> | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4078192#4078192 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4078192

No one faced this problem before? I just wanted to deploy this portlet in a newly installed portal bundle, but it failed, I don't think this is an configuration problem.... can anyone help me?

There's actually a jira feature request for that: http://jira.jboss.com/jira/browse/JBSEAM-1342 I'd like it, too, but it might not come for a little while.

[JBoss Seam] - Custom annotation scanner

by swd847

Would it be possible to add a scanner for custom annotations into seam? I am thinking something along the lines of: 1) Define the annotations that we are interested in in a configuration file, as well as the application scope context variables that they are to be loaded into. 2) When the component scanner runs it also looks for these class level annotations, and loads the class names into a list. 3) These lists are then saved to the application scope. Application scoped components could then use these lists to set up any infrastructure that uses these classes.

Another problem that if a user in frustration clicks multiple times on a link which leads to slow JSF page it practically kills app server for quite some time making it essentially easy denial-of-service attack.

by mgrouch

One more surprising finding with rendering table. I tried to compare rendering time (RENDER phase and overall response time) by rendering same table with regular h:dataTable tag and using facelets ui:repeat like this <table> | <tr jsfc="ui:repeat" value="#{recordList.resultList}" var="record" class="row"> | <td>#{record.id}</td> | ... | </tr> | </table> facelets render it 3 times!!! faster on average (I did number of runs to get good stats). (22 columns, 100 rows) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4078184#4078184 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4078184

I am attempting to migrate an EJB 2 application from JBoss 4.0.3SP1 to 4.2.1.GA. XDoclet is used to generate the ejb files. During server start-up, after rebuilding the ear file, I get the error "Finder findByLevelType defined on ProductDetail should return only instances of ProductDetail but the query results in instances of ProductLevel" The ejbql is defined in ProductLevel but ProductDetail extends ProductLevel. The trace from the server log is: 09:47:20,182 WARN [ServiceController] Problem starting service jboss.j2ee:service=EjbModule,module=bgms_ejb.jar | org.jboss.deployment.DeploymentException: Finder findByLevelType defined on ProductDetail should return only instances of ProductDetail but the query results in instances of ProductLevel | at org.jboss.ejb.plugins.cmp.jdbc.JDBCAbstractQueryCommand.setSelectEntity(JDBCAbstractQueryCommand.java:320) | at org.jboss.ejb.plugins.cmp.jdbc.JDBCEJBQLQuery.(JDBCEJBQLQuery.java:79) | at org.jboss.ejb.plugins.cmp.jdbc.JDBCCommandFactory.createEJBQLQuery(JDBCCommandFactory.java:75) | at org.jboss.ejb.plugins.cmp.jdbc.JDBCQueryManager.start(JDBCQueryManager.java:286) | at org.jboss.ejb.plugins.cmp.jdbc.JDBCStoreManager.startStoreManager(JDBCStoreManager.java:505) | at org.jboss.ejb.plugins.cmp.jdbc.JDBCStoreManager.start(JDBCStoreManager.java:396) | at org.jboss.ejb.plugins.CMPPersistenceManager.start(CMPPersistenceManager.java:172) | at org.jboss.ejb.EjbModule.startService(EjbModule.java:414) | at org.jboss.system.ServiceMBeanSupport.jbossInternalStart(ServiceMBeanSupport.java:289) | at org.jboss.system.ServiceMBeanSupport.jbossInternalLifecycle(ServiceMBeanSupport.java:245) | at sun.reflect.GeneratedMethodAccessor3.invoke(Unknown Source) | at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) | at java.lang.reflect.Method.invoke(Unknown Source) | at org.jboss.mx.interceptor.ReflectedDispatcher.invoke(ReflectedDispatcher.java:155) | at org.jboss.mx.server.Invocation.dispatch(Invocation.java:94) | at org.jboss.mx.server.Invocation.invoke(Invocation.java:86) | at org.jboss.mx.server.AbstractMBeanInvoker.invoke(AbstractMBeanInvoker.java:264) | at org.jboss.mx.server.MBeanServerImpl.invoke(MBeanServerImpl.java:659) | at org.jboss.system.ServiceController$ServiceProxy.invoke(ServiceController.java:978) | at $Proxy0.start(Unknown Source) | at org.jboss.system.ServiceController.start(ServiceController.java:417) | at sun.reflect.GeneratedMethodAccessor9.invoke(Unknown Source) | at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) | at java.lang.reflect.Method.invoke(Unknown Source) | at org.jboss.mx.interceptor.ReflectedDispatcher.invoke(ReflectedDispatcher.java:155) | at org.jboss.mx.server.Invocation.dispatch(Invocation.java:94) | at org.jboss.mx.server.Invocation.invoke(Invocation.java:86) | at org.jboss.mx.server.AbstractMBeanInvoker.invoke(AbstractMBeanInvoker.java:264) | at org.jboss.mx.server.MBeanServerImpl.invoke(MBeanServerImpl.java:659) | at org.jboss.mx.util.MBeanProxyExt.invoke(MBeanProxyExt.java:210) | at $Proxy29.start(Unknown Source) | at org.jboss.ejb.EJBDeployer.start(EJBDeployer.java:662) | at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) | at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) | at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) | at java.lang.reflect.Method.invoke(Unknown Source) | at org.jboss.mx.interceptor.ReflectedDispatcher.invoke(ReflectedDispatcher.java:155) | at org.jboss.mx.server.Invocation.dispatch(Invocation.java:94) | at org.jboss.mx.interceptor.AbstractInterceptor.invoke(AbstractInterceptor.java:133) | at org.jboss.mx.server.Invocation.invoke(Invocation.java:88) | at org.jboss.mx.interceptor.ModelMBeanOperationInterceptor.invoke(ModelMBeanOperationInterceptor.java:142) | at org.jboss.mx.interceptor.DynamicInterceptor.invoke(DynamicInterceptor.java:97) | at org.jboss.system.InterceptorServiceMBeanSupport.invokeNext(InterceptorServiceMBeanSupport.java:238) | at org.jboss.ws.integration.jboss42.DeployerInterceptor.start(DeployerInterceptor.java:93) | at org.jboss.deployment.SubDeployerInterceptorSupport$XMBeanInterceptor.start(SubDeployerInterceptorSupport.java:188) | at org.jboss.deployment.SubDeployerInterceptor.invoke(SubDeployerInterceptor.java:95) | at org.jboss.mx.server.Invocation.invoke(Invocation.java:88) | at org.jboss.mx.server.AbstractMBeanInvoker.invoke(AbstractMBeanInvoker.java:264) | at org.jboss.mx.server.MBeanServerImpl.invoke(MBeanServerImpl.java:659) | at org.jboss.mx.util.MBeanProxyExt.invoke(MBeanProxyExt.java:210) | at $Proxy30.start(Unknown Source) | at org.jboss.deployment.MainDeployer.start(MainDeployer.java:1025) | at org.jboss.deployment.MainDeployer.start(MainDeployer.java:1015) | at org.jboss.deployment.MainDeployer.deploy(MainDeployer.java:819) | at org.jboss.deployment.MainDeployer.deploy(MainDeployer.java:782) | at sun.reflect.GeneratedMethodAccessor54.invoke(Unknown Source) | at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) | at java.lang.reflect.Method.invoke(Unknown Source) | ... | | Any ideas? | | | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4078182#4078182 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4078182
