jndi-name property override - JUnit - Spring - Struts Integration test

I am trying to write integration test that uses JUnit, Struts2, Spring, JPA/Hibernate.

The application is working fine in WebSphere. The Integration tests are run outside of WebSphere.

struts2-junit-plugin and spring-struts plugin both are used. My test class extends StrutsSpringTestCase.

This is the sample code in the test method:

ActionProxy proxy = getActionProxy("custSearch");
assertNotNull(proxy);

It loads struts.xml, applicationContext.xml and jpaContext.xml.

In the jpaContext.xml I have the following entry.

<bean id="dsSQLServer" class="org.springframework.jndi.JndiObjectFactoryBean" p:jndi-name="${sql.jndi.name}"/>

sql.jndi.name comes from the properties file and is setup in WebSphere.

I went TO properties file and replaced the local jndi url with full jndi url that I got from executing dumpNamespaces.bat of Websphere. which is something like

MycomnameNode01Cell/nodes/C1A-mYNode/servers/mYSrv/jdbc/sql_src

However, when I run the JUnit test case from eclipse I get the following exception.

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSourceSQLServer' defined in URL [file:/C:/workspace/context/jpaContext.xml]: Invocation of init method failed; nested exception is javax.naming.NoInitialContextException: Failed to create InitialContext using factory specified in hashtable

Questions:

Should the JNDI URL be different? Is it possible to specify the FULL URL like iiop:localhost:/?
Is it possible to override jndi-name setting in @BeforeClass method or with Static initializer? Because, the JNDI URL above, Provider URL is missing.

Solution

The JNDI context is usually provided by your app server (Websphere). As you're running your test from the outside of Websphere, you won't be able to access to a local JNDI. I see 3 solutions...

Ensure that you're connected to the remote JNDI

You should initialize your access properties in a @BeforeClass method :
```
Hashtable env = new Hashtable();
env.put(Context.PROVIDER_URL, "iiop://server:2809");
env.put(Context.INITIAL_CONTEXT_FACTORY,"com.ibm.websphere.naming.WsnInitialContextFactory");
Context ctx = new InitialContext(env);
```
This way you'll be able to access to the remote JNDI, but a datasource is not supposed to be serialized. It cannot be transfered remotely.
Setup a local JNDI

Spring is providing a SimpleNamingContextBuilder class that can be used in the @BeforeClass method to setup a local JNDI and fill it with a hand made datasource
Don't load the jpaContext.xml file

Make an other one which will provide the dsSQLServer bean, but without accessing the JNDI. A SimpleDriverDataSource would probably be perfect.

My preferred solution is #3.
