Referring to a image file in a JAR file

[Bernard Giannetti <th...@hotmail.com>]

Hi,

I am trying to refer to a graphic file within a JAR file.  The JAR file contains the application which is being executed along with the aforementioned graphic file.

The application is launched via JNLP - so not sure if that effects what I am trying to do.

If the JAR file is myapp.jar and the graphic is say image.svg then the tag

<fo:external-graphic src="file://myapp.jar!/image.svg" content-width=8" content-height="8"> results in the error

Error with opening URL 'file://myapp.jar!/image.svg'

I have tried different variations on the src attribute, say file:/// and then also url('/image.svg') but with similar errors.

Is it possible to reference an image file within the same JAR as the application?


Thanks in advance,

Bernard.

Hi,

we needed exactly that and implemented our own "ResourceResolver" for that.
You can register it like the following:

//Register a custom resolver
foUserAgent.setURIResolver(new ClasspathResourceResolver());

//The clas has to implement the URIResolver
public class ClasspathResourceResolver implements URIResolver {

//you overwrite the resolve method
public InputStream resolve(String uri){

//Resolves the path to a resource in the classpath (since that jar
should be in the classpath
this.getClass().getResourceAsStream(uri);
