JRException Can't read font file (*.ttf) on linux

 

 

Hello everybody,

 

I have a problem with reading file font (ex: Arial.ttf) on linux server

I export the jasper report from my java code, and set a folder for fonts (arabic fonts) under fonts folder on my application

and my java code set PDF font of jasper report to refer to font under this path (ex: /xxx/fonts/Arial.ttf) and set PDFEncoding to be Identity-H to support Arabic and English letters

it works well for me on windows servers for both browsers (internet explorer and Mozilla firefox).

But on linux servers when calling report the page appears blank on firefox browser and i found the following exception:

net.sf.jasperreports.engine.JRException: Could not load the following font :

pdfFontName : /usr/local/tomcat/webapps/xxx/fonts/Arial.ttf

pdfEncoding : Identity-H

isPdfEmbedded : true

Any help will be appreciated.

Is there anything unclear here, any ideas.

[lucianc]

Isn't there any further exception stacktrace? JRException wraps another exception, and the original exception would help identifying the error cause.

no it is the only exception :(

[lucianc]

Try to debug your application and to inspect the exception as thrown by JasperReports. Unless we see the original exception, I don't think we'd be able to tell what caused it.

Now there is no exception appears now after i have changed the *.ttf to *.TTF as Linux is case sensative with finding files where windows is not, i discover that by chance from minutes.

 

But although of that, the report didn't displayed on linux because it throws another exception because i included an image on my report (logo image) and i set image expression to "http://www.upload2world.com/pic63/upload2world_487f0.jpg" from IReport.

 

But it seems that linux can't download image, and throws the following exception:

 

net.sf.jasperreports.engine.JRException: Error loading image data : http://www.upload2world.com/pic63/upload2world_487f0.jpg

and this exception didn't appear before.

Thanks lucianc for help.

Again, the exception stacktrace is not complete. Only the original exception would help identifying the cause.
