Hello,
I am trying to access Oracle data source in Jboss from a struts based web
application. For doing this I have done the following:
i am using Oracle 10g Express edition.
(1) Copied the thin oracle driver (ojdbc14.jar) in server\default\lib directory
of
JBOSS_HOME.
(2) Copied the oracle-ds.xml file from docs\examples\jca directory of
JBOSS_HOME to
server\default\deploy of JBOSS_HOME.
which is :
<local-tx-datasource>
<jndi-name>oracleDS</jndi-name>
<connection-url>jdbc:oracle:thin:@localhost:1521:XE</connection-url>
<user-name>uname</user-name>
pwd
<type-mapping>OracleXE</type-mapping>
</local-tx-datasource>
(3) Next I have changed the default standardjaws.xml. I have changed the data
source
name and its type-mapping to OracleXE.
i added type mapping for Oracle XE simply copeing the content of whole oracle 8
type mapping and just changed its name to OracleXE
java:/oracleDS
<type-mapping>OracleXE</type-mapping>
false
<default-entity>
<create-table>true</create-table>
<remove-table>false</remove-table>
<tuned-updates>true</tuned-updates>
<read-only>false</read-only>
<time-out>300</time-out>
<row-locking>false</row-locking>
<read-ahead>false</read-ahead>
</default-entity>
(4) I have changed standardjbosscmp-jdbc.xml file also.
(5) I have put an entry in login-config.xml file also.
But when i deploy my application
these are the excpetions i get in my server log :---
Caused by: java.lang.ClassNotFoundException: No ClassLoaders found for:
oracle.jdbc.driver.OracleDriver
Could not create deployment:
ile:/usr/local/jboss-4.0.5.GA/server/default/deploy/oracle-ds.xml
please help me out.. i am unable to figure out the problem.
some more desciptive server log dump :
