Struts 2 - JasperReport problem

[jim paolo]

Hello guys! im new to this forum. I just wanted to know how can i display my pdf file into the browser?? I dont want to use the struts 2 jasper-report plugin. anyway, i can create a pdf in an standa-alone application (using static void main()) here's my current code:

package com.jim;

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.io.OutputStream;
import java.sql.Connection;
import java.sql.DriverManager;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.Map;

import model.Person;
import model.Phone;
import net.sf.jasperreports.engine.JREmptyDataSource;
import net.sf.jasperreports.engine.JasperCompileManager;
import net.sf.jasperreports.engine.JasperExportManager;
import net.sf.jasperreports.engine.JasperFillManager;
import net.sf.jasperreports.engine.JasperPrint;
import net.sf.jasperreports.engine.JasperPrintManager;
import net.sf.jasperreports.engine.JasperReport;
import net.sf.jasperreports.engine.design.JasperDesign;
import net.sf.jasperreports.engine.util.JRLoader;
import net.sf.jasperreports.engine.xml.JRXmlLoader;
import net.sf.jasperreports.view.JasperViewer;

import com.opensymphony.xwork2.ActionSupport;

public class JasperAction extends ActionSupport {

    /**
	 * 
	 */
	private static final long serialVersionUID = 1L;
	

    public String execute() throws Exception {
    	try {
    		Class.forName("oracle.jdbc.OracleDriver");
    		Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@//127.0.0.1:1521/XE", "jim", "oracle");
    		System.out.println("Loading Report Designs");
    		InputStream input = new FileInputStream(new File("C:\\SampleReport.jrxml"));
    		JasperDesign jasperDesign = JRXmlLoader.load(input);
    		
    		System.out.println("Compiling Report Designs");
    		JasperReport jasperReport = JasperCompileManager.compileReport(jasperDesign);
    		
    		System.out.println("Creating JasperPrint Object");
    		Map<String, String> parameters = new HashMap<String, String>();
    		parameters.put("ReportTitle", "PDF JasperReport");
    		
    		System.out.println("Filling Report to File");
    		JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, null, conn);
    		JasperViewer.viewReport(jasperPrint, false);
    		//Exporting the report
    		OutputStream output = new FileOutputStream(new File("c:\\rep.pdf"));
    		JasperExportManager.exportReportToPdfStream(jasperPrint, output);
    		JasperPrintManager.printReport(jasperPrint, false);
    		System.out.println("Report Generation Complete");
    		conn.close();
    	} catch (Exception e) {
    	
    	}/*
    	JasperReport jasperReport = (JasperReport)JRLoader.loadObject("C:\\SampleReport.jasper");
    	JasperPrint jasperPrint =JasperFillManager.fillReport(jasperReport, new HashMap(),new JREmptyDataSource()); 

    	JasperPrintManager.printReport(jasperPrint,false); */
       

        return SUCCESS;
        
    }

}

and this is my struts.xml file:

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>
	<constant name="struts.enable.DynamicMethodInvocation"
		value="false" />
	<constant name="struts.devMode" value="false" />

	
	<package name="default" extends="jasperreports-default,struts-default" namespace="/">
		<action name="Login" class="com.jim.UserAction" method="execute">
			<result name="success">/home.jsp</result>
		</action>
		<!--
		<action name="myJasperTest" class="com.jim.JasperAction" method="execute">
			<result name="success" type="jasper">
				<param name="location">/jasper/SampleReport.jasper</param>
				<param name="dataSource">beanCollection</param>
				<param name="format">PDF</param>
			</result>
		</action>-->
		<action name="myJasperTest" class="com.jim.JasperAction" method="execute">
			<result name="success">/home.jsp
			</result>
		</action>
	</package>
	
	
	
	
</struts>

and im using iReport to generate my jrxml file. Thanks!

btw, this is the output:

HTTP Status 404 - result 'null' not found

--------------------------------------------------------------------------------

type Status report

message result 'null' not found

description The requested resource (result 'null' not found) is not available.


--------------------------------------------------------------------------------

Apache Tomcat/6.0.35

You are getting result null but you defined it was success in action class try to debug how it is setting null.
