Why I'm getting the jxls Error : Can't parse an expression rm.exec

Question

Hi,
I used the RowSet in JXLS and it's working perfectly, but I'm getting Error when I use the SQL Reporting in JXLS
Error : java.lang.RuntimeException: Can't parse an expression rm.exec('select name from Designer' )
My Java File :
package net.sf.jxls.report;
import net.sf.jxls.exception.ParsePropertyException;
import net.sf.jxls.transformer.XLSTransformer;
import net.sf.jxls.report.ReportManager;
import net.sf.jxls.report.ReportManagerImpl;
import java.sql.*;
import java.util.Map;
import java.util.HashMap;
public class QReport {
private static String templateFileName = "examples/Report/QReport.xls";
private static String destFileName = "examples/Report/QReport_Out.xls";
public static void main(String[] args) throws Exception, ClassNotFoundException, SQLException {
if (args.length >= 2) {
templateFileName = args[0];
destFileName = args[1];
try {
     Class.forName("sun.jdbc.odbc.JdbcOdbcDriver").newInstance();
     Connection con = DriverManager.getConnection("jdbc:odbc:NewDB");
     Map beans = new HashMap();
     ReportManager reportmanager = new ReportManagerImpl(con, beans);
     beans.put("rm", reportmanager);
     XLSTransformer transformer = new XLSTransformer();
     transformer.transformXLS(templateFileName, beans, destFileName);
}catch(Exception e){
     System.out.println("Error : "+e);
The Excel file as follows
<jx:forEach items="${rm.exec('select name from Designer' )}" var="design">
${design.name}
</jx:forEach>
Thanks in advance.

Hi,
I don't know JXLS and this for sure is the wrong forum to ask this question (I suggest to discuss problems with the source code originator at Sourceforge), however
${rm.exec('select name from Designer' )}"
can't work because by definition, Expression language doesn't take arguments. There is only one option to pass an argument to Expression Language and this is when the method you access in fact is a wrapped hashmap. So my assumption is that the exception occurs because of the wrong use of EL.
If you looked at the sample on SourceForge you could see that I am right
