Configure JNDI names with Open EJB

Question

I'm trying to (unit) test my EJB class without having to startup my websphere environment. Now I'm using Open EJB, but there are some issues with resolving the JNDI Names for other EJBs that are used within my EJB... and there is no way for me to inject mocked classes from my test right now.

Getting the InitialContext

final Properties properties = new Properties();
properties.setProperty(Context.INITIAL_CONTEXT_FACTORY, "org.apache.openejb.client.LocalInitialContextFactory");
properties.setProperty("log4j.category.OpenEJB.options ", "debug");
properties.setProperty("log4j.category.OpenEJB.startup ", "debug");
properties.setProperty("log4j.category.OpenEJB.startup.config ", "debug");
properties.setProperty("MyOwnDatasource.JdbcDriver ", "com.ibm.as400.access.AS400JDBCDriver");
properties.setProperty("MyOwnDataSource.JdbcUrl ", "jdbc:as400:MYHOSTNAME;database name=MYDATABASE;libraries=MYDEFAULTTABLE");
ic = new InitialContext(properties);

Inside my class under test there is a lookup for java:comp/env/ejb/PrefixEjbNameLocalHome and I can not set Open EJB to generate JNDI names in that format.

Additional Property for JNDI name format

I tried setting the formatting rule like this:

properties.setProperty("openejb.jndiname.format ", "comp/env/ejb/{interfaceClass}");

Properties aren't used?

Also the logging configuration isn't used. I'm only seeing INFO and WARN messages from Open EJB, although I set log4j.category.OpenEJB.* and the like to DEBUG or TRACE.

It's the "java:" part that is messing up your test case. Basically Context.INITIAL_CONTEXT_FACTORY and "java:" are mutually exclusive. The InitialContext class has a special understanding of "java:" or any "foo:" lookups and if they are at the beginning of the name it will not use INITIAL_CONTEXT_FACTORY you specified. A somewhat frustrating part of JNDI.

If you lookup the name exactly as printed in the log, it will work. So for example this log message:

INFO - Jndi(name=WidgetBeanRemote) --> Ejb(deployment-id=WidgetBean)

Then in code:

Properties p = new Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY, "org.apache.openejb.client.LocalInitialContextFactory");
// set any other properties you want
Context context = new InitialContext(p);

Object o = context.lookup("WidgetBeanRemote");
