I'm having some trouble with trying to get access to Remote EJBs deployed in an EAR to a Glassfish 3 server.

The EBJs seem to deploy correctly, because when I deploy it says this:

[#|2010-09-02T15:11:17.986-0500|WARNING|glassfish3.0.1|org.apache.catalina.connector.Request|_ThreadID=38;_ThreadName=Thread-1;|PWC4011: Unable to set request character encoding to UTF-8 from context , because request parameters have already been read, or ServletRequest.getReader() has already been called|#] [#|2010-09-02T15:11:19.783-0500|WARNING|glassfish3.0.1|javax.enterprise.system.tools.deployment.org.glassfish.deployment.common|_ThreadID=38;_ThreadName=Thread-1;|appclient module [ReadEDI.jar] contains characteristics of other module type: ejb|#] [#|2010-09-02T15:11:19.845-0500|INFO|glassfish3.0.1|javax.enterprise.system.container.appclient.org.glassfish.appclient.server.core|_ThreadID=38;_ThreadName=Thread-1;|ACDEPL103: Java Web Start services started for the app client ParisEDI/ReadEDI.jar (contextRoot: /ParisEDI/ReadEDI)|#] [#|2010-09-02T15:11:19.876-0500|INFO|glassfish3.0.1|javax.enterprise.system.tools.admin.org.glassfish.deployment.admin|_ThreadID=38;_ThreadName=Thread-1;|ParisEDI was successfully deployed in 1,688 milliseconds.|#] [#|2010-09-02T15:18:50.594-0500|WARNING|glassfish3.0.1|org.apache.catalina.connector.Request|_ThreadID=38;_ThreadName=Thread-1;|PWC4011: Unable to set request character encoding to UTF-8 from context , because request parameters have already been read, or ServletRequest.getReader() has already been called|#] [#|2010-09-02T15:18:50.688-0500|INFO|glassfish3.0.1|javax.enterprise.system.container.appclient.org.glassfish.appclient.server.core|_ThreadID=38;_ThreadName=Thread-1;|ACDEPL104: Java Web Start services stopped for the app client ParisEDI/ReadEDI.jar|#] [#|2010-09-02T15:18:53.453-0500|INFO|glassfish3.0.1|javax.enterprise.system.container.ejb.com.sun.ejb.containers|_ThreadID=38;_ThreadName=Thread-1;|Portable JNDI names for EJB ReadEDI850File : [java:global/ParisEDI/ReadEDI/ReadEDI850File, java:global/ParisEDI/ReadEDI/ReadEDI850File!com.parispresents.edi.readedi.ReadEDI850FileRemote]|#] [#|2010-09-02T15:18:53.453-0500|INFO|glassfish3.0.1|javax.enterprise.system.container.ejb.com.sun.ejb.containers|_ThreadID=38;_ThreadName=Thread-1;|Glassfish-specific (Non-portable) JNDI names for EJB ReadEDI850File : [com.parispresents.edi.readedi.ReadEDI850FileRemote#com.parispresents.edi.readedi.ReadEDI850FileRemote, com.parispresents.edi.readedi.ReadEDI850FileRemote]|#] [#|2010-09-02T15:18:53.625-0500|INFO|glassfish3.0.1|javax.enterprise.system.tools.admin.org.glassfish.deployment.admin|_ThreadID=38;_ThreadName=Thread-1;|ParisEDI was successfully deployed in 2,953 milliseconds.|#]


I use the following code to try and read the EJB:

package com.parispresents.edi.testediclient; import javax.naming.InitialContext; import com.parispresents.edi.readedi.ReadEDI850FileRemote; public class TestEDIClient { /** * @param args */ public static void main(String[] args) { InitialContext ctx; try { ctx = new InitialContext(); ReadEDI850FileRemote edi = (ReadEDI850FileRemote)ctx.lookup("java:global/ParisEDI/ReadEDI/ReadEDI850File"); edi.readFile("Foo"); } catch (Exception e) { e.printStackTrace(); } } }

When I run the code inside of Eclipse, it gives me the following error:

javax.naming.NameNotFoundException: No object bound for java:global/ParisEDI/ReadEDI/ReadEDI850File [Root exception is java.lang.NullPointerException] at com.sun.enterprise.naming.java.javaURLContext.lookup(javaURLContext.java:224) at com.sun.enterprise.naming.SerialContext.lookup(SerialContext.java:407) at javax.naming.InitialContext.lookup(Unknown Source) at com.parispresents.edi.testediclient.TestEDIClient.main(TestEDIClient.java:19) Caused by: java.lang.NullPointerException at com.sun.enterprise.naming.java.javaURLContext.lookup(javaURLContext.java:218) ... 3 more

I have tried both on the remote server and on a server local to the dev environment. I am including the gf-client.jar and the Client EJB Jar in my project, and I've read the Glassfish EJB faq several times to go through different scenarios. This seems like a pretty trivial example, but I can't seem to get it to work. I don't think it's even contactign the glassfish server, because if I change the -Dorg.omg.CORBA.ORBInitialHost property in the VM options, I get the same error. I must be missing some crucial step.


== Thanks.

His has got to be a 'solved' problem before, but I can't seem to come up with the correct combination of google terms to get the answer.

I have a Datatable filled in by a OneToMany relationship off of an Entity(QAHeader) bean. One of the fields in this Entity(QALine) points to another Entity(LineType). I would like the make a selectOneMenu that selects one of the LineType Entities and set the QALine l_type to that Entity.

After some preliminary research, I found out that I have to use a converter. So I wrote a converter to take a string of the LineType ID and return the Object.

*edit* I forgot to mention that the Converter is registered in faces-config.xml

Now I'm getting: [#|2008-09-18T14:01:54.954-0500|INFO|sun-appserver9.1|javax.enterprise.resource.webcontainer.jsf.lifecycle|_ThreadID=17;_ThreadName=httpSSLWorkerThread-8888-1; sourceId=j_id_id16:j_id_id24:2:ccc[severity=(ERROR 2), summary=(j_id_id16:j_id_id24:2:ccc: Validation Error: Value is not valid), detail=(j_id_id16:j_id_id24:2:ccc: Validation Error: Value is not valid)] sourceId=j_id_id16:j_id_id24:0:ccc[severity=(ERROR 2), summary=(j_id_id16:j_id_id24:0:ccc: Validation Error: Value is not valid), detail=(j_id_id16:j_id_id24:0:ccc: Validation Error: Value is not valid)];|WARNING: FacesMessage(s) have been enqueued, but may not have been displayed. sourceId=j_id_id16:j_id_id24:2:ccc[severity=(ERROR 2), summary=(j_id_id16:j_id_id24:2:ccc: Validation Error: Value is not valid), detail=(j_id_id16:j_id_id24:2:ccc: Validation Error: Value is not valid)] sourceId=j_id_id16:j_id_id24:0:ccc[severity=(ERROR 2), summary=(j_id_id16:j_id_id24:0:ccc: Validation Error: Value is not valid), detail=(j_id_id16:j_id_id24:0:ccc: Validation Error: Value is not valid)]|#] Whenever I submit the page, whether I have changed the values or not.

Everywhere I put debug statements the values seem to be valid.

Can anyone point me to a solution?

Datatable:
<h:dataTable border="1" value="#{selectionTracker.selectedQAHeader.lines}" var="line"> <h:column id="column2"> <h:selectOneMenu id="ccc" value="#{line.l_type}" > <f:selectItems value="#{database.selectItemTypes}"/> </h:selectOneMenu> <f:facet name="header"> <h:outputText value="Line Type"></h:outputText> </f:facet> </h:column> </h:dataTable><br>

Converter:
package com.xx.qa.converters; import javax.faces.component.UIComponent; import javax.faces.context.FacesContext; import javax.faces.convert.Converter; import javax.persistence.EntityManager; import com.xx.qa.backing.Database; import com.xx.qa.qadatabase.LineType; public class LineTypeConverter implements Converter { private EntityManager em; public Object getAsObject(FacesContext arg0, UIComponent arg1, String arg2) { LineType lt; Database db; System.out.println(arg2); db = (Database) arg0.getApplication().getExpressionFactory(). createValueExpression( arg0.getELContext(), "#{database}", Database.class).getValue(arg0.getELContext()); em = db.getEm(); lt = em.find(LineType.class, (int)Integer.valueOf(arg2)); return(lt); } public String getAsString(FacesContext arg0, UIComponent arg1, Object arg2) { return String.valueOf(((LineType)arg2).getId()); } }

Here's the function that builds the SelectItem List:
public List<SelectItem> getSelectItemTypes() { List<LineType> ltl; LineType ll=null; List<SelectItem> seli = new ArrayList<SelectItem>(); ltl = em.createQuery("SELECT y FROM LineType y").getResultList(); for(Iterator<LineType> lli = ltl.iterator(); lli.hasNext(); ) { ll=lli.next(); SelectItem si = new SelectItem(ll.getId(),ll.getShortname()); //System.out.println(si.getValue().getClass()); //System.out.println(si.getValue()); //System.out.println(si.getLabel()); seli.add(si ); } return(seli); }

faces-config.xml
<converter> <display-name>LineTypeConverter</display-name> <converter-for-class>com.parispresents.qa.qadatabase.LineType</converter-for-class> <converter-class>com.parispresents.qa.converters.LineTypeConverter</converter-class> </converter>
