net.sf.jasperreports.engine.JRException: Erro

2005-04-19 14:54

Hi,

 

I get this error when executing my java class file. The class file is part of the .ear file and the /lib directory in the .ear file has the jasper jar files.

 

The snippet of the code where my error happens is:

 

try {

log.debug("ready to create the report design template");

reportDesign = createReportTemplate(labelsNoSpace, reportTitle, this.isHTML);

if (reportDesign == null){

log.debug("error while creating the report template.");

}else {

log.debug("report design is compiled");

log.debug("ready to compile the report");

tradeReport = JasperCompileManager.compileReport(reportDesign);

log.debug("report is compiled");

}

}

 

The createReportTemplate method is where I create the template and that is passed onto the compile manager.

 

I'm stuck and any help will be appreciated.

 

Anantha

You did not post the whole error

It would also help to know in which line the error happens (see the stacktrace).

The compiler cannot find the classes.

You must use System.setProperty("jasper.reports.compile.class.path",...) where ... is the path of the jasper jar AND the path to your compiled classes.

Also it might be a good idea to use System.setProperty("jasper.reports.compile.temp",...) to set the path where the .jasper files are stored (unless you get the compiled jasper as a stream and store it yourself).

 

Hope this helps

Hi,

 

Thanks for your reply. One clarification though.

 

1) I have the jasper-0.6.4.jar in my .ear file. So it should be able to find it.

2) I don't have any .jasper files. The code above is in my report class file. I want to create the template at run time and compile the report.

 

Is it possible?

hi buddy,

This code is using jasper to develop report.

I am also using APIs for same but having problem for displaying image on report .

can any body inform me what do we mean by $P, such as $F means field from database and $V means value of variable..

 

how should I display an image by retriving from database or from local disk.

 

and how should I do that.

 

regards,

JAmol

Did you randomly pick a message? Heh.

 

$P means param, as passable in a hashmap.

 

I've found easiest for me is to use a URL, and there was an interestin g post a little while back about using URLs and images from a databse or file system. Very kewl. Just like this project.

 

Good Luck!

If you mean .jasper file with template then yes, it's possible. You can use JasperCompileManager.compileReportToStream(...) to compile a jrxml file/stream to a .jasper file/stream.

I have my files in a .war file myself, and it was necessary to at least set the path of the classes it uses in the way described above to get rid of the same compile errors that you posted.

If you mean .xrxml with template then I guess even that is possible - generate it dynamically, pass it to the compile method mentioned above and use the compiled stream to fill and format the report.

 

Cheers, Lukas

When using a report to Stream compilation approach, it's still needed to set jasper classpath...

however, I have them inside my ear (APP-INFlib) and cannot find a way to set the correct compile path within my code.

Any ideas on this?

Thanks,

Lucas

Instead of trying to compile on runtime now I get all reports pre-compiled during the build (through an ant script and jrc taskdef) and packed inside a jar.

When recovering the report:

URL url = getClass().getClassLoader().getResource("/reportName.jasper");

JasperReport jasperReport = (JasperReport) JRLoader.loadObject(url);

 

It works...and hope this will help someone else.
