Tomcat + Jasperreports Problem

2004-04-27 03:22

Hello,

 

I have a perfectly working test program for making pdf reports on command line. If I take all the .Jar files and put them in the WEB-INF/lib/ and put the modifyed class in WEB-INF/classes I get this error:

 

C:jakarta-tomcat-5.0.19Umsaetze_FX_Swap.java:90: cannot resolve symbol

symbol : variable varsm

location: class Umsaetze_FX_Swap

variable_SummaryDummyGroup_COUNT = (JRFillVariable)varsm.get("SummaryDum

myGroup_COUNT");

The error happens when I try to compile my .xml file. I suspect that there is some kind of path problem but I do not know how to configure Tomcat correctly. The Tomcat version is 5.0.19 and Jasperreports 0.5.2.

 

I hope somebody has an idea because I am seriously stuck.

 

Greetings,

Sven

Hello Teodor,

 

your hint was all I needed.

 

Thank you

 

The 2 lines I needed were :

compile_path="c:/jakarta-tomcat-5.0.19/webapps/etms/WEB-INF/lib/jasperreports-0.5.2.jar;c:/jakarta-tomcat-5.0.19/webapps/etms/WEB-INF/classes";

System.setProperty("jasper.reports.compile.class.path",compile_path);

 

Greetings

Sven

Hi,

 

It is about setting the "jasper.reports.compile.class.path"

system property correctly.

Check the "webapp" sample provided and

the "Quick How To".

 

Thank you,

Teodor

Sven-loe ......

Gr8 that it hepled you ....

 

Teodor,

I m facing problem with blank browser screen.

No error but no report too.

 

Let me know some workaround.

Have got some reports to be generated in pdf

i m using

JDK1.4.xx

WinXp

JRUN server

MS ACCESS

 

Also why ireport generated report properly but webapp fails....

have checked webapp sample.

infact did modified only the connection and the .jasper report in the sample web app.

Still didnt helped.

 

Others have reached to a point wehre they are exlporing abt reports and sub totals.... I m still stucked here with blank screens.... No exception.

 

Need help on streams too.

 

Currently i m callin a bean that generates a pdf rpt on the local drive of server, then i am using jdownload(using pack provided zoom ...) that helps download a report. Its time and resource consuming ....

 

Some working code (other than webapp) attached would do needful for me to explore.

 

Any help / suggestion would be of gr8 help.

Thnx in advance ....

Regards,

Kalpesh N Mistry.

Hi,

I'm generating a JasperDesign object without an xml design.

After doing so, if i try to compile it as -

JasperReport compiledReport = JasperCompileManager.compileReport(design);

//where design is a valid JasperDesign object.

This works in a dos environment.(i'm using a windows 2000 m/c).But the same program doesn't work when running under Tomcat 4.1 .I've seen many posts in this regard, and as mentioned in the "webapp" example I've also updated the properties as shown below:

 

System.setProperty(

"jasper.reports.compile.class.path",

context.getRealPath("/WEB-INF/lib/jasperreports-0.6.0.jar") +

System.getProperty("path.separator") +

context.getRealPath("/WEB-INF/lib/commons-logging-1.0.2.jar") +

System.getProperty("path.separator") +

context.getRealPath("/WEB-INF/classes/")

);

 

But still I'm getting the following error:

 

java.lang.NoClassDefFoundError

Hello Kalpesh N Mistry,

 

you said you have code that generates a pdf file. So I send you some sample code to display it:

 

<%@ page language="java"%>

<%@ page import="dataconn.tmsDataBean" %>

<%@ page import="java.io.*"%>

<%@ page import="java.util.*"%>

<%@ page import="javax.servlet.*"%>

<%@ page import="reports.*"%>

<%

 

////////////////////////////////Print Code///////////////////////

 

ReportGenerator rpg = new ReportGenerator("tms", tmsBean.tmsConn);

ByteArrayOutputStream pdfStream = null;

if(ID.equals("Umsaetze"))

pdfStream = rpg.generateReport("Umsaetze_FX_Termin.xml", CLAUSE+" "+ORDER);

if(ID.equals("Lfd_Erg"))

pdfStream = rpg.generateReport("Lfd_Erg_FX_Termin.xml", CLAUSE+" "+ORDER);

//set the headers. content disposition sets the filename of the download

response.setContentLength(pdfStream.size());

response.setContentType("application/pdf");

response.setHeader("Content-Disposition", "attachment; filename=out.pdf");

BufferedOutputStream bos = new BufferedOutputStream(response.getOutputStream());

try{

pdfStream.writeTo(bos);

bos.flush();

bos.close();

}catch(Exception e) {e.printStackTrace();};

pdfStream.reset();

pdfStream = null;

System.gc();

 

////////////////////////////////Print Code///////////////////////

 

Put it in your .jsp file and test it. The .pdf file should be displayed directly in a pdf viewer.

 

Good Luck

Sven
