JNDI lookup in Websphere

[dudleygb]

Hi all,

I'm struggling with this error. I've included the resource ref in my web.xml and everything deploys cool, when I try do a jee:jndi lookup for my DS, I get the following:

Caused by: org.springframework.jndi.JndiLookupFailureExceptio n: JndiObjectTargetSource failed to obtain new target object; nested exception is javax.naming.ConfigurationException: A JNDI operation on a "java:" name cannot be completed because the serverruntime is not able to associate the operation's thread with any J2EE application component.

It seems to be a configuration error. You have to post you datasource bean config..
but for now make sure to config your spring datasource in this way:

<jee:jndi-lookup id="dataSource" jndi-name="jdbc/yourname" resource-ref="true" />

..and, obviously, make sure that a datasource is configured in websphere!

Hope it may help you

Hi Ghed,
I really appreciate the response.
Here is my ref in web.xml

<resource-ref id="ResourceRef_eeBridgeXADS">
<description>
</description>
<res-ref-name>jdbc/eeBridgeXADS</res-ref-name>
<res-auth>Container</res-auth>
<res-sharing-scope>Shareable</res-sharing-scope>
</resource-ref>

=======================================

here is my spring context.xml jndi lookup

======================================

<jee:jndi-lookup id="dataSource"
jndi-name="jdbc/eeBridgeXADS"
resource-ref="true">
</jee:jndi-lookup>

[Ghed]

Mmm...
1. have you set correctly data source from websphere console or file?
2. try to remove <res-sharing-scope>Shareable</res-sharing-scope>

Hope it helps

Hi Ghed,

Thanx bery much for your ideas and responses. I finally sorted my WAS resource issues. MAN! What an effort!

Heres my resources config steps:

In web.xml I have:
==============

<resource-ref id="ResourceRef_eeBridgeXADS">
<description>
</description>
<res-ref-name>jdbc/eeBridgeXADS</res-ref-name>
<res-auth>Container</res-auth>
<res-sharing-scope>Shareable</res-sharing-scope>
<res-type>javax.sql.DataSource</res-type>
</resource-ref>
<resource-ref id="ResourceRef_eeBridgeXAQConFact">
<description>
</description>
<res-ref-name>jms/eeBridgeQConFact</res-ref-name>
<res-auth>Container</res-auth>
<res-sharing-scope>Shareable</res-sharing-scope>
<res-type>javax.jms.QueueConnectionFactory</res-type>
</resource-ref>

In WAS I have DS and Q Conn Factory configured with jndi names like:
================================================== ===
eeBridgeConFact
eeBridgeXADS

When I deploy the webapp, WAS asks me to map the resources in the web.xml to the appserver jndi names.

My Spring Int context file has the resources declared as such:
===============================================

<jee:jndi-lookup id="dataSource"
jndi-name="java:comp/env/jdbc/eeBridgeXADS"
resource-ref="true">
</jee:jndi-lookup>

<jee:jndi-lookup id="connectionFactoryMQ"
jndi-name="java:comp/env/jms/eeBridgeQConFact"
resource-ref="true">
</jee:jndi-lookup>

[Ghed]

Glad to hear your news!
Enjoy now!
