[JBoss Seam] - Re: Removing Stateful Session Beans from the Session gracefu

by Oberiko

Oh, I should have asked. I assume "foo" refers to the Seam component name? Is there a way to get this without typing it in directly (i.e. "this.getContextName()" or some such thing) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4121044#4121044 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4121044

[JBoss Seam] - Re: Can I inject a session bean into a stateless session bea

by gus888

Sorry Pete, What I am asking is whether I can inject a SFSB into a SLSB, e.g. inject user or username into a SLSB, see codes in the first posting. Thanks.

[JBoss Seam] - Re: Beginner question on Seam-gen entity annotations

by pete.muir＠jboss.org

I personally would much prefer the EntityHome approach to annotating entities. I the aim is to not have to write entityHome.instance.property, then just add a factory to components.xml <factory name="entityName" value="#{entityHome.instance}" /> Why? I think the lifecycle is much clearer like this, you get EntityHome (which is very nice), and you are cluster safe.

[Clustering/JBoss] - stored procedures + distrib cache + ejb3 + hibernate

by seahawk＠volny.cz

Hi, I'm trying to find out if it is possible to use stored procedures + distrib cache + ejb3 + hibernate. Scenario: the SF ejb3 should call jee5 (hibernate's) persistence manager native query which should do for example update through stored procedure which I have to use in my architecture. My question is if the cluster (based on hibernate's 2nd level cache) will able to handle it and if this is 'cluster-safe' ... Sorry if I'm not clear enough in my question ... please let me know if you need more information. thanks a lot!

[JBoss Seam] - @DataModelSelection always returns first row

by seyan

Hello, I have a problem with outjecting @DataModelSelection from one bean to another. The first bean ("browseBusinessOperationsForm") is a stateful session bean which keeps @DataModel list and the second bean ("businessOperationForm") is a stateful conversation scope bean and @DataModelSelection is injected to it with variable selectedOperation. It should works like that, when user clicks button in the dataTable row (filled with @DataModel) on browseOperation page, the show() method from "businessOperationForm" bean is invoked and the long runing conversation with custom id is started. After show() method execution, user is redirected to second page with details of operation. But this @DataModelSelection injection doesn't work, I always get the first row from dataTable no matter which row I click. Any ideas what I'm doing wrong? Thanks, Sejan | @Stateful | @Name("browseBusinessOperationsForm") | @Scope(ScopeType.SESSION) | | public class BrowseBusinessOperationsFormAction implements BrowseBusinessOperationsForm { | | @In | private EntityManager em; | | // private TreeState treeState; | | private TreeNode rootNode = null; | | private TreeNodeData<Tag> selectedNode = null; | | private int dataScrollerRow = 0; | | @DataModel(value="operations") | private List<BusinessOperation> operations; | | @DataModelSelection(value="operations") | @Out(required=false) | private BusinessOperation selectedOperation; | | @Out(required=false) | private BusinessOperation operation; | | @In | private FacesContext facesContext; | ....} | | @Stateful | @Name("businessOperationForm") | @Scope(ScopeType.CONVERSATION) | | public class BusinessOperationFormAction implements BusinessOperationForm { | | | @In | private EntityManager em; | | @In | private FacesMessages facesMessages; | | @In(required = false) @Out(required = false) | private BusinessOperation operation; | | @In(required = false) | private BusinessOperation selectedOperation; | | @In | Identity identity; | | @Logger | Log log; | | | @Begin (id="operation=#{selectedOperation.id}") | public String show() { | log.info("show ref: [#0] - started", this); | log.info("show ref: [#0] - conversation started", this); | log.info("show ref: [#0] - operation id: #1 name: #2", this, selectedOperation.getId(), selectedOperation.getName()); | | operation = em.find(BusinessOperation.class, selectedOperation.getId()); | | log.info("show ref: [#0] - passed", this); | | return "businessOperation"; | } | ....} | And below is a snippet from browseOperation page with dataTable: | <ui:define name="contentWithNavigation"> | <rich:panel id="browseOperationPanel"> | <f:facet name="header"> | <h:outputText value="#{messages['browseBusinessOperation.browseOperationLabel']}"/> | </f:facet> | <h:form id="browseBussinesOperationForm"> | <rich:datascroller id="operationDataScroller" | align="center" | for="operationDataTable" | ajaxSingle="true" | ignoreDupResponses="true" | pageIndexVar="pageIndex" | pagesVar="pages"> | </rich:datascroller> | <h:dataTable id="operationDataTable" | value="#{operations}" | var="varOperation"> | | <h:column> | <f:facet name="header"> | <h:outputText value="#{messages['browseBusinessOperation.operationVersionLabel']}" /> | </f:facet> | <h:outputText | value="#{varOperation.version}.#{varOperation.subVersion}.#{varOperation.buildVersion}" /> | </h:column> | <h:column> | <f:facet name="header"> | <h:outputText value="#{messages['browseBusinessOperation.operationAsigneeLabel']}" /> | </f:facet> | <h:outputText value="#{varOperation.asignee}" /> | </h:column> | <h:column> | <f:facet name="header"> | <h:outputText value="" /> | </f:facet> | <h:commandButton id="showBusinessOperationButton" | value="#{messages['browseBusinessOperation.showOperationButton']}" | action="#{businessOperationForm.show}"> | </h:commandButton> | </h:column> | </h:dataTable> | </h:form> | </rich:panel> | </ui:define> | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4121037#4121037 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4121037

[JBoss Seam] - Re: Beginner question on Seam-gen entity annotations

by jpbievenour

Thanks for your reply, Pete. So if I wanted to make Seam manage the entity, I could remove the home entity (which extends EntityHome and gives you persist, delete, edit, etc), annotate the entity with "@Name" and then reference the entity in a xhtml file using | #{EntityName.propertyName} | Is that correct?

[Persistence, JBoss/CMP, Hibernate, Database] - Observing connection usage

by breako

Hi, My application is using an Oracle datasource, which is defined in configuration file which I name oracle-ds.xml which I drop into JBoss. I give it the JNDI name: <jndi-name>jdbc/OracleDSLocal</jndi-name> which my application then looks up. I wondering though, is there any way I can information on 1. Is a connection pool being used? 2. When a connection is actually in use? Webshpere has an application called Tivoli where I can get this info, just wondering does JBoss have anything similar.

by pete.muir＠jboss.org

It's not if you don't want the entity to be a Seam component. You can use a Seam component like EntityHome to manage the entity instead.

by pete.muir＠jboss.org

What are you asking? Yes, of course you can inject an SLSB into a SFSB. The standard rules of session propagation apply.
