My Java code and SQL proc look like below.
Java code
m_connection.createStatement().execute("exec MSG_SNAPSHOT()");
sql Proc
CREATE OR REPLACE PROCEDURE MSG_SNAPSHOT AS
BEGIN
     EXECUTE IMMEDIATE 'TRUNCATE TABLE REVISION_MESSAGE';
     INSERT INTO REVISION_MESSAGE (PK_ID, MSGSTATE, SCHEDSTATE, EXTERN_ID, OBJECT_NAME, PROCESS_AT)
     SELECT msg.PK_ID, msg.MSGSTATE, msg.SCHEDSTATE, msg.EXTERN_ID, msg.OBJECT_NAME, msg.PROCESS_AT
     FROM MESSAGE partition (non_final) msg WHERE msg.SCHEDSTATE <> -1;
END;
Here my problem is I get --->
java.sql.SQLException: ORA-00900: invalid SQL statement

Just a quick check under java.sql.Connection found:
prepareCall
public CallableStatement prepareCall(String sql)
throws SQLException
Creates a CallableStatement object for calling database stored procedures.
Isn't this what you should be using and not createStatement() ?
