NameNotFoundException: Object not found in lookup

[Former Member]

Hi all!

I have a problem with my Netweaver SP18 WebAS EJB application. The JNDI lookup fails with the following runtime error:

com.sap.engine.services.jndi.persistent.exceptions.NameNotFoundException: Object not found in lookup of CaTreeServerIFBean.

I use the following code to lookup the EJB:

Object homeTreeObj = ctx.lookup("sap.com/anafee-server-ear/CaTreeServerIFBean");

I think the JNDI name should be right, because it's a composite name

of "provider-name/application-name/EJB-name".

My provider-name is defined in the application-j2ee-engine.xml:

<application-j2ee-engine>

<provider-name>sap.com</provider-name>

<fail-over-enable mode="disable" />

</application-j2ee-engine>

My application-name is defined in the application.xml:

<application>

<display-name>anafee-server-ear</display-name>

<description>EAR description</description>

<module>

<ejb>anafee-server-ejb-3_2.jar</ejb>

</module>

</application>

My Session EJB is declared in the ejb-jar.xml:

<session>

<description>test</description>

<ejb-name>CaTreeServerIFBean</ejb-name>

<home>com.catenic.anafee.server.common.serverinterface.CaTreeServerIFHome</home>

Do you have any idea why the lookup fails? (I don't have any special JNDI mappings

defined in the ejb-j2ee-engine.xml, if this could matter.)

Hi, Experts,

I have same exceiption as this one, my error message as:

com.sap.engine.services.jndi.persistent.exceptions.NameNotFoundException: Object not found in lookup of Route.

I register in Object: "Route" using JNDI in my RMI over IIOP server. However in my SAP Web Dynpro application, the javaBean model cannot talk with external RMI over IIOP server. my source code as:

Context ctx = new InitialContext();

Object obj = ctx.lookup("Route");

route = (Route)PortableRemoteObject.narrow(obj, Route.class);

How to make SAP J2EE server talk with external Cobra Server?

Hi Gunter,

Try "localejbs/sap.com/anafee-server-ear/CaTreeServerIFBean" as JNDI name.

Best regards, Maksim Rashchynski.

There is no local interface defined according to the ejb-jar.xml above, hence "localejbs/" context is not relevant in this case.

Hi Matthias,

Where are you doing the lookup from? Are you sure that the application has been deployed and started successfully?

Hint: You can use the LSN telnet command from the NAMING group or the JNDI registry browser in the Visual Admin to check the JNDI contents of your server.

HTH!

Hi Vladimir, many thanks.

My server app is deployed and started successfully, I checked this with

the Visual Administrator tool.

My client application runs on a different maschine, but the remote connect

to the server was successfully.

Regards,

Matthias

[Vlado]

OK, but have you tried to locate your EJB in the JNDI registry?

Best regards,

Vladimir
