Hi, all, I am using JBoss 2.4.4 with Sybase 11.5. I am writing a custom finder method for a CMP bena which looks like:
public Collection ejbFindByDateTime(String time) throws FinderException
{
Connection con = null;
if(debug) System.out.println("position 1");
try
{
con = getConnection();
if(debug) System.out.println("position 2 con = " + con);
PreparedStatement statement = con.prepareStatement(
"SELECT max(ID) from TABLE_TEST where ID like ?" );
if(debug) System.out.println("position 3.1 statement = " + statement);
statement.setString(1, time);
if(debug) System.out.println("position 3.2 statement = " + statement);
ResultSet resultSet = statement.executeQuery();
if(debug) System.out.println("positon 4");
LinkedList queryMatches = new LinkedList();
if(debug) System.out.println("position 5");
while(resultSet.next())
{
queryMatches.add(resultSet.getString("ID"));
if(debug) System.out.println("positon 6");
}
if(debug) System.out.println("result size = " + queryMatches.size());
resultSet.close();
statement.close();
return queryMatches;
}
catch ( SQLException sqle )
{
if(debug) System.out.println("position -1");
throw new EJBException(sqle);
}
finally
{
try
{
if(con != null)
{
con.close();
}
}
catch ( SQLException sqle ) {}
}
}
After successfully deploying the bean and run it, the executtion never reaches "positon 4", instead it reached "position -1". That means the PreparedStatement throws some exception. Anyone please help.
By the way, the same SQL can be executed in command line.
The running result are as follows:
...
position 1
position 2 con = org.jboss.pool.jdbc.xa.wrapper.XAClientConnection@753293
position 3.1 statement = org.jboss.pool.jdbc.PreparedStatementInPool@4478fe
position 3.2 statement = org.jboss.pool.jdbc.PreparedStatementInPool@4478fe
position -1
...
Thanks in advance,
