running iReport in jar files

2003-12-07 23:20

Has anyone tried running iReport in jar files? I tried to jar iReports 0.2.2 (everything under classes), with the manifest shown here:

 

Main-Class: it.businesslogic.ireport.gui.MainFrame

Class-Path:

commons-beanutils.jar

commons-collections.jar

commons-digest.jar

commons-logging.jar

commons-logging-api.jar

itext-0.96.jar

iTextAsian.jar

jakarta-poi-1.5.1-final-20020615.jar

jasperreports-0.5.0.jar

jcommon-0.8.0.jar

jconn2d.jar

jfreechart-0.9.8.jar

tools.jar

xercesImpl.jar

xmlParserAPIs.jar

 

 

(Note: all the jar file names are on the same line as the Class-Path:, separated by space).

 

Once I got the iReport.jar file, I placed the iReport.jar in the same directory as those jar files, ie, in the lib directory. I could start the iReport, create new doc, open existing doc. However, I could not compile the new or old doc. Clicked the compile button showed "Compiling to file... C:testtest.jasper -> C:cvs_treeiReport2libtest.java" at the bottom. That is it. No other error message. Looking into the code looks like

the line "JasperCompileManager.compileReportToFile()" in the IReportCompiler.java throws exception. I did have the jasperreports-0.5.0.jar in the lib direcotory.

 

By the way, the iReport ran well using the iReport.bat come with the package, after modified the path.

 

Any comment is highly appreciated.

A correction on my earlier post. The line

 

JasperCompileManager.compileReportToFile()

 

did not throw exception, it never returned. I have tried to replace the call with

 

JasperDesign jasperDesign =

JasperManager.loadXmlDesign(inputStream);

JRBshCompiler theCompiler = new JRBshCompiler();

JasperReport result =

theCompiler.compileReport(jasperDesign);

 

and found out that the loadXmlDesign() never returned (The inputStream is not null, I checked it).

It turned out that the Classpath in my manifest mispelled the commons-digester.jar to commons-digest.jar. Anyway, after corrected it, this problem solved, even though the iReport.jar still does not work. When I start the iReport.jar with

 

java -jar iReport.jar

 

in the lib directory, iReport complained about

 

package dori.jasper.engine does not exist

import dori.jasper.engine.*;

 

Somehow the system could not find the class path, even though they are specified in the manifest. Any suggestion?
