Subject Tomcat Pool and XA datasource
Date Tue, 12 Jul 2011 12:27:41 GMT
Hello all,

Has anyone ever been able to successfully setup an Oracle XA datasource using the newer Tomcat
Pool and running Tomcat 7?  It appears the Tomcat Pool is attempting to cast the oracle XA
data source to a java.sql.Driver - which it isn't.  This needs to be an XA datasource.  Anyone
have luck with this - no working examples that I can find?  Here's the versions/info/error:

Software:
Tomcat 7.0.16
Tomcat Pool 1.1.0.1 http://people.apache.org/~fhanik/jdbc-pool/v1.1.0.1/apache-tomcat-jdbc-1.1.0.1-bin.zip
Oracle 11 (ojdbc6.jar)


Context.xml contents:
<Resource
                                auth="Container"
                                type="javax.sql.XADataSource"
                                factory="org.apache.tomcat.jdbc.pool.DataSourceFactory"
                                driverClassName="oracle.jdbc.xa.client.OracleXADataSource"
                                name="jdbc/mydatabase"
                                username="username"
                                password="password"
                                url="jdbc:oracle:thin:@localhost:1521:XE" />
