Simon Steiner commented on FOP-2861:
------------------------------------
You can intercept the resource loading:
ResourceResolver resolver = {color:#000080}new {color}ResourceResolver() {
{color:#000080}public {color}OutputStream getOutputStream(URI uri)
{color:#000080}throws {color}IOException {
URL url = getServletContext().getResource(uri.toASCIIString());
{color:#000080}return {color}url.openConnection().getOutputStream();
}
{color:#000080}public {color}Resource getResource(URI uri)
{color:#000080}throws {color}IOException {
{color:#000080}return new
{color}Resource(getServletContext().getResourceAsStream(uri.toASCIIString()));
}
};
FopFactoryBuilder builder = {color:#000080}new
{color}FopFactoryBuilder({color:#000080}new
{color}File({color:#008000}"."{color}).toURI(), resolver);
> Allow resource loading from jar: URI

> Key: FOP-2861
> URL: https://issues.apache.org/jira/browse/FOP-2861
> Project: FOP
> Issue Type: Improvement
> Affects Versions: 2.0, 2.1, 2.2, 2.3
> Reporter: Ole Sandum
> Priority: Major
> Attachments: FopResourceResolver.java, uri_resolve.diff
>
>
> We would like to load our FOP config.xml along with related fonts and
> hyphenation files using the common classloader URL, e.g.:
> {{ URL configXml = getClass().getResource("config.xml");}}
> {{ FopConfParser confParser = }}
> {{ new FopConfParser(configXml.openStream(), configXml.toURI());}}
> This makes for easy deployment, and works nicely as long as classes and
> resources are loaded from separate files, i.e. from
> file:/some/path/config.xml URIs. However, it fails when classes and resources
> are packaged and loaded directly from a jar, i.e. from
> jar:file:/some/archive.jar!/path/config.xml URIs, as is the case when
> deploying with JWS or running an all-in-one executable jar, as it will fail
> to properly resolve the related font and hyphenation file URIs.
> See [https://github.com/osandum/fop-test.git] for a test to illustrate.
> This is a consequence of a long standing issue (reported in
> [https://bugs.openjdk.java.net/browse/JDK-8020755)] that
> URI.resolve(childUri) doesn't work as expected on jar:file: URIs.
> In this case, it can be easily remedied by a work-around to the call in
> InternalResourceResolver.resolveFromBase(URI uri). Patch attached.
