[EJB/JBoss] - Problem by jndi-lookup from Tomcat to JBoss

by thomas2008ch

Hi all, I use the XDoclet to build EJB2-porject. The EJB2-project is deployed in JBoss 4.2.2. GA. I can access/connect to the bean from an jsp (index.jsp) in a war: | ... | <body> | <% | com.zoo.Tiger tiger = null; | try{ | com.zoo.TigerHome home = com.zoo.TigerUtil.getHome(); | tiger = home.create(); | | }catch(Exception exception) | { | | } | %> | <b><%= tiger.roar() %></b> | </body> | ... | The war is included within an ear deployed on JBoss. I can even access/connect the bean on the server with a standalone java: | public class TestClient { | | public static void main(String[] args) { | Tiger tiger = null; | try { | TigerHome home = TigerUtil.getHome(); | tiger = home.create(); | System.out.println(tiger.roar()); | | } catch (Exception exception) { | exception.printStackTrace(); | } | } | } | With a jndi.properties: | java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory | java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces | java.naming.provider.url=localhost:1099 | Now I deploy the web/war on Tomcat 6 and try to access/connect to the bean on JBoss. But it failed. My "index.jsp" looks as follow: | <body> | <% | Properties props = new Properties(); | props.put(Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory"); | props.put(Context.PROVIDER_URL, "jnp://localhost:1099"); | | com.zoo.Tiger tiger = null; | try{ | com.zoo.TigerHome home = com.zoo.TigerUtil.getHome(); | tiger = home.create(); | | }catch(Exception exception) | { | | } | %> | <b><%= tiger.roar() %></b> | </body> View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4153212#4153212 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4153212

[EJB 3.0] - Re: Bean Managed Transaction: No JTA transaction found

by ALRubinger

Been awhile since I did BMT; you might also try creating your EntityManager *after* starting the JTA Transaction, seeing if that will enlist it with the Tx in the current Thread.

[EJB 3.0] - Re: Bean Managed Transaction: No JTA transaction found

by rituraj_tiwari

No. I did not realize that would be needed since it seems to work just fine when invoked from session beans. I want to use the same, working infrastructure, but from a worker thread. That being said, this is my persistence.xml: | <persistence-unit name="MyProject"> | <provider>org.hibernate.ejb.HibernatePersistence</provider> | <jta-data-source>java:/MyProjectDatasource</jta-data-source> | <properties> | <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"/> | <property name="hibernate.hbm2ddl.auto" value="update"/> | <property name="hibernate.show_sql" value="true"/> | <property name="hibernate.format_sql" value="true"/> | <property name="jboss.entity.manager.factory.jndi.name" value="java:/MyProjectEntityManagerFactory"/> | </properties> | </persistence-unit> | Thanks for your help in the wee hours of the morning! -Raj View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4153206#4153206 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4153206

Have you defined your EntityManager as "resource-local" in persistence.xml? S, ALR View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4153205#4153205 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4153205

[EJB/JBoss] - Doing persistence operations in worker threads

by rituraj_tiwari

Folks, I am running into a problem where I have come to a dead end after following several leads. I am launching an operation asynchronously in a separate thread which gathers some info and then starts persisting some entities. Problem is, I cannot seem to get anything written to the database. My current approach is to get the EntityManagerFactory and UserTransaction in my worker thread by doing a JNDI lookup: | InitialContext ctx = new InitialContext(); | EntityManagerFactory emf = (EntityManagerFactory)ctx.lookup( "java:/MyProjectEntityManagerFactory" ); | UserTransaction ut = (UserTransaction)ctx.lookup( "java:comp/UserTransaction" ); | | EntityManager em = em = emf.createEntityManager(); | As soon as the last line above is executed, I see the following message in my JBoss log file: | 2008-05-25 01:14:30,093 DEBUG [org.hibernate.impl.SessionImpl] opened session at | timestamp: 4963136594300928 | 2008-05-25 01:14:30,093 DEBUG [org.hibernate.ejb.AbstractEntityManagerImpl] Looking for a JTA transaction to join | 2008-05-25 01:14:30,093 DEBUG [org.hibernate.ejb.AbstractEntityManagerImpl] No JTA transaction found | All persistent operations seem to work, but nothing gets written to the DB. I see the following log messages in server.log: | 2008-05-25 01:21:20,718 DEBUG [org.hibernate.event.def.AbstractSaveEventListener] delaying identity-insert due to no transaction in progress | Is there anything I can do to start a JTA transaction? My environment is JBoss 4.2.2 and Seam 2.x Thanks. -Raj View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4153204#4153204 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4153204

[EJB 3.0] - Re: Bean Managed Transaction: No JTA transaction found

by rituraj_tiwari

Al, Thanks for your response. I am doing ut.begin() right after I create the user transaction. This is a simplified version of my worker thread's method: | InitialContext ctx = new InitialContext(); | EntityManagerFactory emf = (EntityManagerFactory)ctx.lookup( "java:/MyProjectEntityManagerFactory" ); | UserTransaction ut = (UserTransaction)ctx.lookup( "java:comp/UserTransaction" ); | | EntityManager em = emf.createEntityManager(); | | ut.begin(); | doPersistentStuff(em); | ut.commit(); | I am making sure that there is a single thread that creates EntityManagerFactory, EntityManager and performs the persistent operations.

I don't see in your code samples where you're calling UserTransaction.begin()... S, ALR View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4153201#4153201 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4153201

[EJB 3.0] - Re: Bean Managed Transaction: No JTA transaction found

by rituraj_tiwari

An update on this issue: I moved the entity manager creation code inside my worker thread so as to skirt any issues with transactions being threadlocal etc. I stilll cannot find a way to get a JTA transaction: | ... | | InitialContext ctx = new InitialContext(); | EntityManagerFactory emf = (EntityManagerFactory)ctx.lookup( "java:/MyProjectEntityManagerFactory" ); | | UserTransaction ut = (UserTransaction)ctx.lookup( "java:comp/UserTransaction" ); | | ... | I am able to get a hold of valid objects. Still, I get the same messages about no JTA transactions being found. Of course, any persistent operations I do get queued up and don't get written to the database. Is this a known bug in JBoss' EJB3 or Hibernate layers? I have been hammering on this problem for three days non-stop. Any help from someone out there will be greatly appreciated. Thanks. -Raj View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4153200#4153200 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4153200

[JBoss Portal] - Re:

by pavel.myshkin

No easy way you can have portals in portals.. better think of some other architecture.. Sub admins is easy - just make a simple portlet and use JBoss Portal API to manage the users of the portal but to enforce the subset of admins you need to implement is by yourself or use a JBP with properly configured LDAP View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4153196#4153196 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4153196
