[JBoss Seam] - [JBSEAM-1302]: Conversion support for selectMany for Set imp

by fhh

Hello! I am also experiencing problems with <s:entityconverter /> and a set as a backing bean. Lists work, Sets do not. I remember a similar bug report which was closed by Pete Muir. He said the limitations of using a selectMany with a set was actually a limitation of the jsf specification. (http://jira.jboss.com/jira/browse/JBSEAM-1152) At the end of that issue he posted a link to the jsf RI docs http://java.sun.com/javaee/javaserverfaces/1.2/docs/api/javax/faces/compo... My reading of the documentation would be that you can not use a set UNLESS you specified a converter which would be fine for me. Is that correct? The obvious work around of using lists instead of sets is not possible for me because of the "cannot fetch multiple bags" problems. It would be great if someone could tell me if it is possible and where to start to get this working. If this is a real limitation of the jsf specification please close 1302 as a duplicate of 1152. Regards Felix P.S.: Using entityConverter I always get the error message | com.sun.facelets.tag.MetaRulesetImpl finish | SCHWERWIEGEND: /benutzer/edit.xhtml @53,77 entityClass="my.example.clazz" Unhandled by MetaTagHandler for type org.jboss.seam.ui.EntityConverter | Might this be related?

[JBoss Seam] - Re: ClassCastException: org.jboss.seam.jsf.SeamApplication11

by titou09

cool, but the questions behind my problem were: 1) do you have to use MyFaqes instead of the JSF implementation of WAS (Is it your case)? 2) Indeed, if you put all your code in the war, seam works, but this is not acceptable to us. We have to separate our sevices/managers/model classes into a "utility" jar and have the war depends on it, and only have classes related to presentation in the war (view controllers/backing beans). This seems to not be possible if you want to uses seam annotation in any class in the utility jar, as jboss-seam.jar must be placed in the ear file directly has any other framework jar (log4j, etc..). and as you point it out, this does not work A workaround is to have an utility jar for the "business" classes and deploy it under the war WEB-INF/lib directory....arghh See my other posts in tha forum on that topic.

[JBoss Seam] - Re: Calling merge/persist even not called....

by fhh

Hello Mahesh! I cannot check at the moment but I guess that "EXTRANET_MISC"."ORDERSTARTER_ART"."ART_NR" has a "not null" constraint. (If it does not it should have :-)) I suspect the error is not even related to your code since the code you have shown does not attempt to update the data. But it is possible that a query forces a flush of the entitymanager.

[EJB/JBoss] - any idea to inject a ejb to tapestry?

by phoenix.zhp

hi, I use tapestry as web tier and want get a slsb in this tier. this is my code: public abstract class Home extends BasePage { // @EJB // Calculator bean; public String getResult() { // Double message = bean.calculate(11, 22, 0.08, 44); // return message.toString(); InitialContext ctx = null; Calculator bean = null; try { ctx = new InitialContext(); bean = (Calculator) ctx .lookup("ejb3TapestryJboss/CalculatorBean/local"); } catch (NamingException e) { e.printStackTrace(); } Double message = bean.calculate(22, 22, 0.08, 22); return "ok! " + message.toString(); } } When I use JNDI's lookup, as showed above, it works. But when I want to inject a slsb to this page, as the commented code showed, it get nothing. No bean is injected. do I misues this annotation? and how can I inject a bean to tapestry? or I can only do this in servlet? By the way, I use jbossAs 5 beta2 as the server. Thanks for your help in advance.

[Installation, Configuration & Deployment] - Re: basic 4.2 deploy and missing javax.servlet files

by schmaggis

when you created a new server-runtime in eclipse did you select JBoss 4.2.0 or JBoss v4.0? i had a problem lately that JBoss 4.2.0 und JBoss 5.0.0 weren't displayed so i selected JBoss v4.0 and a message appeared there were some files missing, same files you mentioned. I don't know if it's the same Problem, but I learned after some searching that the server description files for the new JBoss-server versions were missing. I found some here: www.informatik.fh-wiesbaden.de/~knauf/public/ If you selected JBoss 4.2.0 when creating a server please ignore this post :) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4046664#4046664 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4046664

by jowizzle

I just found the native libraries. However, I can't seem to find any documentation regarding JBoss version compatibility or installation instructions. Any suggestions? Thanks!

[Clustering/JBoss] - Re: Sever Failover

by bstansberry＠jboss.com

Best thing to do is to have a look at the 4.2 codebase, cluster module, package org.jboss.ha.singleton. HASingletonElectionPolicy is the interface; HASingletonElectionPolicySimple is the default implementation. What you do is you deploy your policy as an mbean. Your policy can take whatever config attributes you want; just expose them in the mbean interface. Then in the mbean descriptor for the HASingletonController you inject the policy. E.g.: | <server> |  | <mbean code="org.jboss.ha.singleton.examples.HASingletonMBeanExample" | name="jboss.examples:service=HASingletonMBeanExample_1"> | </mbean> | | <mbean code="org.jboss.ha.singleton.PreferredMasterHASingletonElectionPolicy" | name="jboss.examples:service=HASingletonMBeanExample-HASingletonElectionPolicy_1"> | <attribute name="PreferredServer">foo:1099</attribute> | </mbean> | | <mbean code="org.jboss.ha.singleton.HASingletonController" | name="jboss.examples:service=HASingletonMBeanExample-HASingletonController_1"> | | <depends optional-attribute-name="ClusterPartition" | proxy-type="attribute">jboss:service=DefaultPartition</depends> | <depends>jboss.examples:service=HASingletonMBeanExample_1</depends> | <depends optional-attribute-name="ElectionPolicy" | proxy-type="attribute">jboss.examples:service=HASingletonMBeanExample-HASingletonElectionPolicy_1</depends> | <attribute name="TargetName">jboss.examples:service=HASingletonMBeanExample_1</attribute> | <attribute name="TargetStartMethod">startSingleton</attribute> | <attribute name="TargetStopMethod">stopSingleton</attribute> | <attribute name="TargetStopMethodArgument">true</attribute> | </mbean> | </server> Your election policy will have a ref to the HAPartition passed into it as an arg to pickSingleton when it needs to decide if it is the master. From that you can determine who the members are. You then compare the value of your PreferredServer attribute to the addresses in the view. If one matches, return that member. If none match, delegate to HASingletonElectionPolicySimple (which should be the superclass of your policy). The tricky bit is "PreferredServer" is a string, while the members are objects of type ClusterNode. As the JIRA says, we need to come up with a good, user-friendly way to compare those.
