Hi,
I could get round this by using in the fopservlet, but I think its a
security issue allowing filesystem access from tomcat
public Resource getResource(URI uri) throws IOException {
if (uri.toASCIIString().startsWith("file:")) {
return new Resource(new FileInputStream(uri.getPath()));
}
return new
Resource(getServletContext().getResourceAsStream(uri.toASCIIString()));
}
Thanks

More info
I have several servlets and FOs to test the various combinations:
http://localhost:8080/fop/fop?fo=C:/temp/readme.fo ; works OK
http://localhost:8080/fop/fop?fo=C:/temp/readmeX.fo ; fails
http://localhost:8080/fop/fopX?fo=C:/temp/readmeX.fo ; fails
http://localhost:8080/fop/fopZ?fo=C:/temp/readmeX.fo ; fails
FopServlet.java ; as distributed
FopServletX.java ; attempt to read custom configuration fop.xml
FopServletZ.java ; attempt to read custom configuration fop.xml
/ custom Resolver
Readme.fo ; as distributed works with:
http://localhost:8080/fop/fop?fo=C:/temp/readme.fo
ReadmeX.fo ; external-graphic included
Fop.xml ; as distributed with base = .
The batch command generates the PDF successfully (attached):-
"C:\fop-2.2\fop\fop.bat" -fo=C:/temp/readmeX.fo -pdf
"C:/temp/FOP-ReadmeX-fo.pdf" > glw-FO.txt 2>&1

It's been a while, but shouldn't it throw a nicer message than an NPE? Maybe
something like "Oh, hello. We see you've not entered a path standard URI
format. Instead you've entered '<something>'. Please check and try again".
Then again, FOP's never been that user friendly! I might look into it
myself.

Hi,
FOP from version 2 using standard URI format for pathes.
So you need to set the pathes in this format also in your FOP config and in
FO.
Ie.: /C/Temp/tomcat.gif or ///C/Temp/tomcat.gif
Best regards, Szeak

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?
