FOP 1.1 to 2.2 Migration - SEVERE Error with External Graphics

Graeme Wellington

Hi

 

I have just migrated to FOP 2.2 - I am using apache-tomcat-8.5.29 / Java 1.8

 

I am using a FOP servlet to render PDF form XML data source.

 

I have a basic example that works on FOP 1.1 but not FOP 2.2

 

http://localhost:8080/fop/fopZ?fo=C:/temp/readme.fo

 

The readme.fo comes with the FOP distribution.

 

Without change the servlet works ok and I get a PDF.

 

When I try and add 1 line to include an image I get SEVERE error as below.

 

I have tried various permutations if the following lines separately but no luck :

 

<fo:external-graphic src="C:/Temp/tomcat .gif"/>

OR

                <fo:external-graphic src="tomcat.gif"/>  

                OR

                <fo:external-graphic src="../graphics/tomcat.gif"/>  

                …

 

I have loaded the tomcat.gif at the various locations to match.

 

However I do not think it is getting that far.

 

I have a customised configuration file and have set the base as follows:

 

<base>./</base>

 

 

Can anyone help?
