Helvetica.afm exists but not found

2004-01-02 10:55

Hi,

I recently upgraded to jasper 0.5.0 and itext 0.96.

 

When attempting to generate a PDF file I now get:

 

Helvetica not found as resource. (The *.afm files must exist as resources in the package com.lowagie.text.pdf.fonts)

ExceptionConverter: com.lowagie.text.DocumentException: Helvetica not found as resource. (The *.afm files must exist as resources in the package com.lowagie.text.pdf.fonts)

The file Helvetica.afm does exist in the fonts directory of the itext jar mentioned.

 

Previously I was running with jasper 0.4.1 and itext 0.92 and didn't have

this problem. My app is deployed via Java Web Start. I believe there is something about the way resources are loaded that if failing.

 

Thanks

John

I stumbled across the answer which is to ensure that any package from which resources need to be loaded also contains at least one java class file that is loaded into the application before any of the resources are accessed. So in my case I created an empty class called ResourceAnchor.class, patched it into com.lowagie.text.pdf.fonts within the itext jar and made sure I created an object of that class near the start of my app.

If anyone can tell me why this works I'd love to know. Something to do with the fact the itext jar is deployed via Java Web Start I believe.

I'll include a dummy class in any package that has only resources in the next version of iText, just in case.

The java class loaders work in mysterious ways and so do the application servers. The Oracle AS is paradigmatic: the behavior depends on the java version and whether iText is inside a jar or expanded to a directory.
