No suitable Log constructor

[alfie17]

I've a jsp that intended to generate a simple jasperreport, but it didnt went too well. I'm using Jasperreports-1.3.3.jar and received the following errors:

 

org.apache.commons.logging.LogConfigurationException: No suitable Log constructor

 

JSP Code

Code:

<%@ page import="net.sf.jasperreports.engine.*"%>
<%@ page import="org.apache.log4j.xml.DOMConfigurator" %>
<%@ page import="java.util.*"%>
<%@ page contentType="text/html;charset=windows-1252"%>
<%
        Map parameters = new HashMap();
        
        DOMConfigurator.configureAndWatch(application.getRealPath("/"«») + "/log4j.xml"«»);  
        JasperReport jasperReport = JasperCompileManager.compileReport(application.getRealPath("/"«») + "Report.jrxml"«»);                     
        JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, parameters);
        net.sf.jasperreports.engine.JasperExportManager.exportReportToPdfFile(jasperPrint,application.getRealPath("/"«») + "abc.pdf"«»);
%>

 

I've tried to turn off the logger but same message appeared. Pls advise. Thx.

 

 

Code:

[code]<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE log4j:configuration SYSTEM "log4j.dtd"> <log4j:configuration xmlns:log4j='http://jakarta.apache.org/log4j/'> <appender name="dbAppender" class="org.apache.log4j.jdbc.JDBCAppender"> <layout class="org.apache.log4j.PatternLayout"> <param name="ConversionPattern" value="proc_testing"/> </layout> </appender> <logger name="net.sf.jasperreports"> <level value="OFF"/> </logger> <root> <priority value="INFO"/> <appender-ref ref="dbAppender"/> </root> </log4j:configuration>
