Unable lookup Datasource from EJB

Question

I am unable to lookup the datasource from my entity bean. I am using BMP in Weblogic
81. The call in the bean is :
ds = (DataSource)jndiContext.lookup("java:comp/env/jdbc/myPool");
I get the following exception:
javax.naming.LinkException: . Root exception is javax.naming.NameNotFoundExcept
ion: While trying to lookup 'jdbc.myPool' didn't find subcontext 'jdbc' Re
solved ; remaining name 'jdbc/myPool'
at weblogic.jndi.internal.BasicNamingNode.newNameNotFoundException(Basic
NamingNode.java:869)
at weblogic.jndi.internal.BasicNamingNode.lookupHere(BasicNamingNode.jav
In my config.xml file, I have the pool setup as:
<JDBCConnectionPool DriverName="oracle.jdbc.OracleDriver"
Name="myPool" Password="{3DES}PKeN6pXlt/o="
Properties="user=dmluser" Targets="myserver"
TestConnectionsOnCreate="true" TestConnectionsOnReserve="true"
TestTableName="SQL SELECT 1 FROM DUAL" URL="jdbc:oracle:thin:@localhost:1521:DEV"/>
<JDBCTxDataSource JNDIName="myPool" Name="myPool"
PoolName="myPool" Targets="myserver"/>
Any ideas of what might be wrong?
Thanks

Answer 1

You have defined the datasource with a global JNDI name, so
jndiContext.lookup("myPool") would work.
java:/comp/env is a JNDI namespace local to your component. So if you
will need to add a mapping in your BMP's ejb-jar.xml and
weblogic-ejb-jar.xml that maps comp/env/jdbc/myPool to the myPool name
in the global JNDI.
