Deploying the application in a file.jar

2002-12-12 03:12

Hi,

 

I have a problem with:

I generated my application in a file.jar. In this file are included the files .jasper.

 

To get the path to these files I use:

URL u = new classN().getClass().getResource(namefile);

return u.getFile();

 

then I have this path: file:c:packagefile.jar!comreport.jasper

 

but I receive one exception:

 

dori.jasper.engine.JRException:

file:c:packagefile.jar!comreport.jasper

 

This path is correct, but I think that Jasper is doesn't finding this file.

What can I do to find a file.jasper inside a file.jar ?

 

Thank you,

Acharat

Don't use the URL.getFile() method rather the ClassLoader.getResourceAsStream() method and pass on the stream to jasper. This should work whereever you place the files (as long the classloader can load them ...)

Thank you for your answer.

 

But I forgot to tell that I need to use the path of the jasper file to the method:

 

JasperFillManager.fillReportToFile(fileName, parameters, classBD);

 

This method requires a String or a JasperReport object in the first parameter, then I cannot pass a getResourceAsStream as you told me to.

 

Do you have any sugestion ?

 

Thank you again,

Acharat
