[JBoss Seam] - Re: Tomcat + Embedded EJB

by KnisterPeter

When I change my EJB to have the EntityMangager annotated with @In instead of @PerstistenceContext it does get deployed in the ejb server , but then no EntityManager is injected and I get the following exception when calling a method on that bean: org.jboss.seam.RequiredException: In attribute requires non-null value: register.em | org.jboss.seam.Component.getValueToInject(Component.java:1919) | org.jboss.seam.Component.injectAttributes(Component.java:1368) | org.jboss.seam.Component.inject(Component.java:1195) | org.jboss.seam.interceptors.BijectionInterceptor.aroundInvoke(BijectionInterceptor.java:46) | org.jboss.seam.intercept.SeamInvocationContext.proceed(SeamInvocationContext.java:69) | org.jboss.seam.interceptors.MethodContextInterceptor.aroundInvoke(MethodContextInterceptor.java:27) | org.jboss.seam.intercept.SeamInvocationContext.proceed(SeamInvocationContext.java:69) | org.jboss.seam.intercept.RootInterceptor.invoke(RootInterceptor.java:103) | org.jboss.seam.intercept.SessionBeanInterceptor.aroundInvoke(SessionBeanInterceptor.java:53) | sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) | sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) | sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) | java.lang.reflect.Method.invoke(Method.java:597) | org.jboss.ejb3.interceptor.InvocationContextImpl.proceed(InvocationContextImpl.java:118) | org.jboss.ejb3.interceptor.EJB3InterceptorsInterceptor.invoke(EJB3InterceptorsInterceptor.java:63) | org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) | org.jboss.ejb3.entity.TransactionScopedEntityManagerInterceptor.invoke(TransactionScopedEntityManagerInterceptor.java:54) | org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) | org.jboss.ejb3.AllowedOperationsInterceptor.invoke(AllowedOperationsInterceptor.java:47) | org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) | org.jboss.aspects.tx.TxPolicy.invokeInOurTx(TxPolicy.java:79) | ...

[JBoss Seam] - Re: DataModel using Set does not work

by andreigh.ts

There is something weird how this @DataModel functions, maybe it can be documented somewhere. In my example the @DataModel exposes the Set of a hibernate entity(from one-many relationship). If the @DataModel is a property of a stateful bean (conversation scope), then modifying the hibernate set, automatically updates the DataModel (this means that somehow seam links the DataModel to the original object; it does not clone the collection?) But if @DataModel is a property of a stateless bean, then modifying the hibernate set has no effect in the user interface. I'm confused ... it's a bug?

[JBoss Seam] - Re: Tomcat + Embedded EJB

by KnisterPeter

One thing to add here is when I'm using java:/DefaultDS in my persistence.xml as jndi-datasource hibernate is started while deploying my app, when using my own specified datasource it does not get started. Any clue what is need to use my own datasource?

[JBoss Seam] - Seam application packaging question

by leezard

Hi all, I'm trying to build seam sample application using maven. I have only a few dependencies in my project: seam-1.2.1, seam-ui-1.2.1, facelets and java5 api (just for development). Now when I package whole application into EAR maven includes all seam's dependencies into this EAR. Those dependencies are: hibernate-annotatnions asm hibernate commons-logging jta persistence-api asm-attrs antlr jms javaassist ecache dom4j cglib commons-collections I read "packaging" chapter of seam doc, and there is shown sample EAR structure of seam application. There are only a few jars included: seam seam-ui facelets el-api el-ri Now, do I have to exclude all the dependencies from my EAR and include only jars mentioned in seam doc? Are the other jars avalilable in Jboss already?

[JBoss Seam] - @In @Out @In(create=true) confusion

by dreuzel

The problem with annotation is that one does not understand what happens behind the screen. I'm using a ejb3-hibernate entity definition(simply defined) in the pojo @In tableclass xyz is used I'm sometimes receving exceptions the xyz nullpointer exception because (i think) I conditionaly use XYZ IN MY FACELET xhtml definition depending on some other pojo variable i render the variables pointing to XYZ, conditionaly as in some cases xyz.variables(the prime key) are not rendered the @in initialized xyz is not initialised... ====> exception the exception occurs during page initialisation, during the rendering, prior to calling @begin so there is very little i can do to solve the bug it does not help using @out nor @in(create=true) can anyone confirm my theory ??? (seam 1.2.1) any chance for improvement with 1.3 ?

[JBoss Seam] - Re: DataModel using Set does not work

by petemuir

Because JSF supports sets and arrays natively, but not Sets - Seam does some trickery there. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4054243#4054243 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4054243

[JBoss Seam] - Re: DataModel using Set does not work

by andreigh.ts

Thanks, it works. Now I understand, @DataModel outjects a brand new object with a new name (default variable name). This also means that the variable should be created with @Factory (usually). Now I don't understand why my initial approach worked with List and array :) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4054240#4054240 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4054240
