BC4J Integration With JBOSS --------------------------- Key: EJBTHREE-2267 URL: https://issues.jboss.org/browse/EJBTHREE-2267 Project: EJB 3.0 Issue Type: Feature Request Components: ejb3 Environment: OS - Microsoft Windows Vista 1GB RAM JBOSS 4.2.2 GA Application Server Reporter: Nikunj Kakkad Assignee: Carlo de Wolf Priority: Critical Labels: BC4J, JBOSS, Oracle, WrappedPreparedStatement I am trying to deploy an Oracle BC4J Application to JBOSS 4.2.2 GA Application Server. The problem I am having is that JBOSS uses 'Wrapped' Classes for connections, prepared statements, etc... I have used OraclePreparedStatement and JBOSS tries to cast it into WrappedPreparedStatement which gives ClassCastException.....here's a stacktrace : Caused by: java.lang.ClassCastException: org.jboss.resource.adapter.jdbc.WrappedPreparedStatement at oracle.jbo.server.OracleSQLBuilderImpl.doStatementSetRowPrefetch(OracleSQLBuilderImpl.java:1071) at oracle.jbo.server.DBTransactionImpl.createPreparedStatement(DBTransactionImpl.java:3405) at oracle.jbo.server.DBTransactionImpl2.createPreparedStatement(DBTransactionImpl2.java:428) at oracle.jbo.server.DBTransactionImpl.createReUsePreparedStatement(DBTransactionImpl.java:4239) at oracle.jbo.server.ViewObjectImpl.getPreparedStatement(ViewObjectImpl.java:8202) at oracle.jbo.server.QueryCollection.buildResultSet(QueryCollection.java:746) at oracle.jbo.server.QueryCollection.executeQuery(QueryCollection.java:666) at oracle.jbo.server.ViewObjectImpl.executeQueryForCollection(ViewObjectImpl.java:3655) at oracle.jbo.server.ViewRowSetImpl.execute(ViewRowSetImpl.java:742) at oracle.jbo.server.ViewRowSetImpl.executeQueryForMasters(ViewRowSetImpl.java:891) at oracle.jbo.server.ViewRowSetImpl.executeQueryForMode(ViewRowSetImpl.java:805) at oracle.jbo.server.ViewRowSetImpl.executeQuery(ViewRowSetImpl.java:799) at oracle.jbo.server.ViewObjectImpl.executeQuery(ViewObjectImpl.java:3575) Any idea would be greatly appreciated.
