Tried again...Actually this happens only with one WAR file in Beta 4. I am using OracleRowSet there . My spring-context.xml is as follows :- <?xml version="1.0" encoding="UTF-8"?> | <beans xmlns="http://www.springframework.org/schema/beans" | xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" | xmlns:jee="http://www.springframework.org/schema/jee" | xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd | http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-2.0.xsd"> | <jee:jndi-lookup id="jndiDs" jndi-name="jdbc/TestDs" resource-ref="true"/> | <bean name="/home" class="com.myapp.struts.action.SpringStrutsAction" | autowire="byName"> | <property name="dao" ref="intf" /> | </bean> | <bean name="intf" class="com.myapp.db.DAOImpl"> | <property name="rowSet" ref="oracleRowSet" /> | <property name="dataSource" ref="jndiDs" /> | </bean> | <bean name="oracleRowSet" class="oracle.jdbc.rowset.OracleCachedRowSet"> | <property name="type" value="1004" /><!--ResultSet.TYPE_SCROLL_INSENSITIVE--> | <property name="concurrency" value="1008" /><!--ResultSet.CONCUR_UPDATABLE--> | </bean> | </beans> | My bean code is as follows :- /* | * DAOImpl.java | * | * To change this template, choose Tools | Template Manager | * and open the template in the editor. | */ | | package com.myapp.db; | | import java.sql.Connection; | import java.sql.SQLException; | import javax.sql.DataSource; | import javax.sql.RowSet; | import javax.sql.rowset.CachedRowSet; | import org.springframework.jdbc.support.JdbcUtils; | import javax.sql.rowset.spi.SyncProviderException; | import oracle.jdbc.rowset.OracleCachedRowSet; | import org.apache.struts.action.ActionForm; | import org.apache.struts.action.DynaActionForm; | | public class DAOImpl implements DAOIntf{ | | //Spring Injected | private DataSource ds; | private CachedRowSet rowSet; | | public Connection getConnection() throws SQLException { | return this.ds.getConnection(); | } | | | public void setDataSource(DataSource datasrc) { | this.ds = datasrc; | } | | public DataSource getDataSource() { | return this.ds; | } | | public CachedRowSet getRowSet() { | return this.rowSet; | } | | public void setRowSet(CachedRowSet r) { | this.rowSet = r; | } | | public RowSet getBooks(int isbn) { | | Connection conn = null; | | try { | conn = getConnection(); | rowSet.setCommand("select ISBN,TITLE,AUTHOR,RATING,PRICE from BOOKROWSET where isbn = " + isbn); | rowSet.execute(conn); | } catch (SQLException ex) { | ex.printStackTrace(); | } finally { | JdbcUtils.closeConnection(conn); | } | return rowSet; | } | | | public RowSet getAllBooks() { | | Connection conn = null; | | try { | conn = getConnection(); | rowSet.setCommand("select ISBN,TITLE,AUTHOR,RATING,PRICE from BOOKROWSET "); | rowSet.execute(conn); | } catch (SQLException ex) { | ex.printStackTrace(); | } finally { | JdbcUtils.closeConnection(conn); | } | return rowSet; | } | | public RowSet addBooks(ActionForm form) { | | rowSet = getRowSet(); | | try { | rowSet.setReadOnly(false); | rowSet.afterLast(); | rowSet.moveToInsertRow(); | rowSet.updateDouble(1,(Double)(((DynaActionForm)form).get("isbn"))); | rowSet.updateString(2,(String)(((DynaActionForm)form).get("title"))); | rowSet.updateString(3,(String)(((DynaActionForm)form).get("author"))); | rowSet.updateString(4,(String)(((DynaActionForm)form).get("rating"))); | rowSet.updateDouble(5,(Double)(((DynaActionForm)form).get("price"))); | rowSet.insertRow(); | rowSet.setReadOnly(true); | rowSet.beforeFirst(); | commit(rowSet); | } catch(SQLException sqe) { | sqe.printStackTrace(); | } | | return rowSet; | | } | | public RowSet deleteBook(ActionForm form) { | | rowSet = getRowSet(); | try { | rowSet.setReadOnly(false); | rowSet.absolute(Integer.parseInt((String) (((DynaActionForm)form).get("rowNo")))); | rowSet.deleteRow(); | rowSet.setReadOnly(true); | rowSet.beforeFirst(); | commit(rowSet); | } catch(SQLException sqe) { | sqe.printStackTrace(); | } | return rowSet; | | } | | private void commit(RowSet r) { | | Connection conn = null; | | try { | conn = getConnection(); | OracleCachedRowSet rowSet = (OracleCachedRowSet)r; | rowSet.acceptChanges(conn); | } catch (SyncProviderException ex) { | ex.printStackTrace(); | } catch(SQLException sqe) { | sqe.printStackTrace(); | } finally { | JdbcUtils.closeConnection(conn); | } | | } | | | } | Error from jboss 5 beta 4 is :- If I remove this WAR file, everything appears fine....Surprising this was that this was working with spring 2.0...Moment I upgraded to spring 2.5 I started to get this error....Checked out the spring forums & they say it is becos spring is returning a proxy instead of OracleCachedRowSet...Question is why should spring 2.5 do this ? OracleCachedRowSet implements javax.sql.rowset.CachedRowset & jdk proxy should be ok ...Else jboss 5 beta 4 seems to be ok....Guess this is something with spring 2.5....To be sure I deployed this WAR in tc 6 and had the same error 16:35:55,625 INFO [TransactionAttributeClassProcessor] org.jboss.metadata.ejb.spec.ContainerTransactionMetaData@1f | 16:35:58,078 WARN [ClassLoaderManager] Unexpected
