11:07 a.m.
having problems seeting up the embedded server for EJB3 so that i can run outside an app
server.
imported a bootsrap main programme from hibernate chapter 2 into an Eclipse project
where i have a structure as
| src
| NeilsApp2.java (default package)
| objectModel
| more java files ...
| ejb3-interceptors-aop.xml
| jndi.properties
| log4j.properties
| META-INF
| persistence.xml (for mysql)
| neilsapp-beans.xml (ds for the beans)
|
|
| import objectModel.TestHandler;
|
| import org.jboss.ejb3.embedded.EJB3StandaloneBootstrap;
| import javax.naming.InitialContext;
|
| public class NeilsApp2
| {
|
| public static void main(String[] args) throws Exception {
| // Boot the JBoss Microcontainer with EJB3 settings, automatically
| // loads ejb3-interceptors-aop.xml and embedded-jboss-beans.xml
| EJB3StandaloneBootstrap.boot(null);
| // Deploy custom stateless beans (datasource, mostly)
| EJB3StandaloneBootstrap
| .deployXmlResource("META-INF/NeilsApp-beans.xml");
| // Deploy all EJBs found on classpath (slow, scans all)
| // EJB3StandaloneBootstrap.scanClasspath();
| // Deploy all EJBs found on classpath (fast, scans build directory)
| // This is a relative location, matching the substring end of one
| // of java.class.path locations. Print out the value of
| // System.getProperty("java.class.path") to see all paths.
| EJB3StandaloneBootstrap.scanClasspath("helloworld-ejb3/bin");
| // Create InitialContext from jndi.properties
| InitialContext initialContext = new InitialContext();
| // Look up the stateless MessageHandler EJB
| TestHandler tstHandler = (TestHandler) initialContext
| .lookup("TestHandlerBean/local");
| // Call the stateless EJB
| tstHandler.testMessage();
| // Shut down EJB container
| EJB3StandaloneBootstrap.shutdown();
| }
| }
|
and unpacked the embedded server release 9 patch 1 into a jboss install dir.
Now we get the problems. The book said I should have an embedded-jboss-beans.xml file.
However there is not one of these to be found in the
E:\jboss\jboss-EJB-3.0_RC9_Patch_1 directories at all.
further, included the /lib jar files into my class path and Eclipse couldnt resolve
org.jboss.ejb3.embedded an any of the jars.
I have partially fixed that by donwloading the full jboss AS5 beta - and eventually found
a version of E:\jboss\jboss-5.0.0.Beta1\server\all\deployers\ejb3.deployer\jboss-ejb3.jar
which had the org.jboss.ejb3.embedded package defined within in.
couldnt find on the the EJB3 download at all.
so i finally the code and it fails looking for the embedded-jboss-beans.xml.
couldnt find one of these anywhere so i copied a default from one of the html files as
this

I have included just about every jar file in evey /lib and /client directores in the
jboss as5 and other directories - no soap.
just how are you supposed to get this blasted embedded server to run!! The documentation
and tutorials dont help me - theres nothing to explain how to setup the ejb3 standlone
properly strainght from the download .
Can any help in simple terms for idiots (me), what we are supposed to do get the embedded
server running outside of an AS as a standalone application.
unhappy in ipswich !
