Good Morning.
I've got a problem using Hibernate 3.0.0, JBoss 5.1.0GA and jdk1.6
here is a log of error:

And here is a code that cause that error:
public void query(String query)
{
manager.createNativeQuery(query).executeUpdate();
manager.clear();
manager.flush();
}
Error shows every time I do insert/update/delete query.
If you need more info please ask.
Thank You in advance.
I finally found a workaround. In a seperate EJB, use the following code:
public class MyEJB {
#PersistenceContext
private Session session;
public final void update(int param) {
this.session.doWork(new UpdateWork(param));
}
private class UpdateWork implements Work {
private final int param;
public UpdateWork(int param) {
this.param = param;
}
/**
* {#inheritDoc}
*/
#Override
public void execute(Connection connection) throws SQLException {
PreparedStatement statement = connection.prepareStatement(query);
int updated = statement.executeUpdate();
statement.setInt(1,param);
if (updated > 0) {
// stuff
}
}
}
}
It seems that your transaction is already committed. Maybe you should create a new transaction to perform this operation in.
This is a Hibernate bug:
https://hibernate.onjira.com/browse/HHH-3818
Upgrading your version of Hibernate to a version greater than 3.3.2 should resolve the issue.

I was using Apache Commons DBCP (commons-dbcp-1.2.2.jar) Connection pool and importing org.apache.commons.dbcp.DelegatingConnection.
Due to some performance isues, I upgraded to commons-dbcp2-2.1.1.jar and imported org.apache.commons.dbcp2.DelegatingConnection.
But while executing getting following Exception
java.lang.ClassCastException: org.apache.commons.dbcp.DelegatingCallableStatement cannot be cast to oracle.jdbc.OracleCallableStatement
Any idea why is this coming.
Java Code
public static Connection getOracleConnection(java.sql.Connection con) throws SQLException
{
Connection oracleCon = null;
if(con instanceof com.p6spy.engine.spy.P6Connection)
{
oracleCon = (oracle.jdbc.OracleConnection)((P6Connection)con).getJDBC();
}
else if(con instanceof P6LogConnection)
{
oracleCon = (oracle.jdbc.OracleConnection)((P6LogConnection)con).getJDBC();
}
else if(con instanceof DelegatingConnection)
{
Object innerMostObj = ((DelegatingConnection)con).getInnermostDelegate();
if(innerMostObj instanceof oracle.jdbc.OracleConnection )
{
oracleCon = (oracle.jdbc.OracleConnection)innerMostObj;
}
else if(innerMostObj instanceof P6LogConnection)
{
oracleCon = ((P6LogConnection)innerMostObj).getJDBC();
}
else if(innerMostObj instanceof P6Connection)
{
oracleCon = ((P6Connection)innerMostObj).getJDBC();
}
}
else
{
oracleCon = con;
}
return oracleCon;
}

I'm currently working on a xCP 2.0 project with Documentum 7.0 and I'm trying to run a Java Service inside a workflow. The Java Service works alright when the function I use does no more than return a "some_string" String. But as soon as I try the actual thing and use documentum specific Objects like:
IDfSession mySession = getSession();
I get these exceptions right here:

Am I missing something?

System.out.println(list);
}
}
rs.beforeFirst();
}
System.out.println(list);

list.addAll(set);
list.removeAll(Collections.singleton(null));
con.close();
} catch (SQLException e) {

}
return list;
Here I'm trying to search through my records to check whether a particular set of keywords are present in the record. I tried almost everything cant figure out the error.. I think its with the statement "rs.beforeFirst()" because it is only printing for the first iteration.. Following is from the console..

"because it is only printing for the first iteration."
From the ResultSet javadoc.
A default ResultSet object is not updatable and has a cursor that moves forward only. Thus, you can iterate through it only once and only from the first row to the last row. It is possible to produce ResultSet objects that are scrollable and/or updatable. The following code fragment, in which con is a valid Connection object, illustrates how to make a result set that is scrollable and insensitive to updates by others, and that is updatable. See ResultSet fields for other options.
Statement stmt = con.createStatement(
ResultSet.TYPE_SCROLL_INSENSITIVE,
ResultSet.CONCUR_UPDATABLE);
ResultSet rs = stmt.executeQuery("SELECT a, b FROM TABLE2");
// rs will be scrollable, will not show changes made by others,
// and will be updatable
Here's how I would write that class, based on what you've posted:
package persistence;
import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.util.ArrayList;
import java.util.List;
/**

public class BookDao {

this.con = con;

while(rs.next()) {
list.add(rs.getString(1));

You do a lot of things that are either unnecessary or incorrect.

}
}
System.out.println("status update"+status);
return status;
}
catch(Exception e)
{

return 2;
}
}
FUNCTION 2
public List<ModuleUser> fetchUserStatus(int id) {
try
{
session=sessionFactory.getCurrentSession();
SQLQuery m=session.createSQLQuery("select * from users");
return m.list();
}
catch(Exception e)
{
e.printStackTrace();
return null;
}
}
Can anyone suggest what is the wrong with the code?
Raw query in this case returns scalar values:
List<Object[]>
where array contains raw columns from result query.
Probably you want something like this:
SQLQuery m=session.createSQLQuery("select * from users").addEntity(ModuleUser.class);
Is ModuleUser a mapped #Entity? If yes use HQL instead of native query
List<ModuleUser> users = session.createQuery("from ModuleUser").list()
Else if you are forced to native SQL use #aim solution
This is my method which talks to the database with JPA:
public Collection<ModuleConnection> getConnections(int parentModuleId) {
Query query = em.createQuery("SELECT moduleConnection FROM ModuleConnection As moduleConnection WHERE moduleConnection.parentModule = :parentModuleId");
query.setParameter("parentModuleId", parentModuleId);
List<ModuleConnection> cons = query.getResultList();
return cons;
}
I am calling this method like this:
Collection<ModuleConnection> connections = bh.getConnections(module.getModuleId());
Everytime I do this, I get this exception:

11:38:03,373 ERROR [CachedConnectionValve] Application error: jsp did not complete its transaction
This is how the table looks like:
CREATE TABLE "MODULECONNECTION"
(
"ID" NUMBER(10,0) NOT NULL ENABLE,
"QUANTITY" NUMBER(10,0) NOT NULL ENABLE,
"PARENTMODULE_MODULEID" NUMBER(10,0),
"SUBMODULE_MODULEID" NUMBER(10,0)
)
Any idea how I can fix this?
I think your query should just be
SELECT moduleConnection FROM ModuleConnection As moduleConnection
WHERE moduleConnection.parentModule.id = :parentModuleId
You could use your original query if the argument of the query was of type Module (the type of the associated entity, and not the type of its ID)
