JRResultSetDataSource problem

2003-04-16 15:52

I'm having difficulty passing a JRResultSetDataSource to my report and getting it to fill.


I create the JRResultSetDataSource in a bean, and store it as a session attribute, as follows:


String sql = new String("select CUST__T, CUST_NAME from CUSTOMER");

stmt = conn.prepareStatement(sql);

rs = stmt.executeQuery();

ds = new JRResultSetDataSource(rs);



.....and then try to use it in my JSP as follows:


JRResultSetDataSource ds = (JRResultSetDataSource) session.getAttribute("QueryTestDataSource");

JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport,parameters,ds);


I should note that I have a similar report which contains a SQL query, and a similar bean-JSP pair, which works flawlessly.


I have checked and double-checked my report definition file vs. my PreparedStatement, and both contain the same columns.


I also have debug writes to logs, and I can definitely see that the ResultSet from which Icreate the JRResultSetDataSource has about 30 rows. Also, I've written "ds" out to the log both in the bean and after I retrieve it from the HTTP session, and the signature is the same.


However, whatever I do, I get a "Unable to get next record" error when I run. What am I doing wrong?
