connection OK in JSP but fail in java!
Hi,
I just config a datasource 'oracle-ds.xml' in my JBoss322, and in a JSP file i can connect it well. But a single java class gives 'javax.naming.NameNotFoundException: OracleDS not bound'. Why?
thanks in advance...

Here are a couple of the possible OCI configurations.
For more information, see http://otn.oracle.com/docs/products/oracle9i/doc_library/release2/java.920/a96654/toc.htm
<connection-url>jdbc:oracle:oci:@youroracle-tns-name</connection-url>
or
<connection-url>jdbc:oracle:oci:@(description=(address=(host=youroraclehost)(protocol=tcp)(port=1521))(connect_data=(SERVICE_NAME=yourservicename)))</connection-url>
Clearly, its better to have TNS set up properly.
