I am trying to use jndi datasource of jboss, in an external standalone java program. But when i access any method in DatabaseMetaData which returns ResultSet i get the error
$Proxyxxx cannot be cast to java.sql.ResultSet
I am using jboss-eap-5.1, JDK 1.6.0_38, oracle linux 6.1.
Java program has the following lib in its class path
jboss-client.jar
jboss-common-core.jar
jboss-integration.jar
jboss-javaee.jar
jboss-logging-spi.jar
jboss-remoting.jar
jboss-security-spi.jar
jboss-serialization.jar
jbosscx-client.jar
jbosssx-client.jar
jnp-client.jar
jboss-common-jdbc-wrapper.jar
Java code snippet
final Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
env.put(Context.PROVIDER_URL, "jnp://localhost:1999");
final Context ctx = new InitialContext(env);
final Object lobj = ctx.lookup("MyJNDI");
final DataSource source = (DataSource) lobj;
final Connection connection = source.getConnection(); //success
final DatabaseMetaData data = connection.getMetaData();
final ResultSet resultSet = data.getSchemas(); //error in this line
I have exposed the jndi setting in my *-ds.xml file by adding the jndi name to global context (as per Exposing/Accessing JBoss JNDI Objects/Datasources From an External JVM | engfer(s) ).
How can i solve this issue?
Note: Inside the webapp if i print datasource class name i get org.jboss.resource.adapter.jdbc.WrapperDataSource. But in java program i get java.lang.Proxy.
