-------------------------------------------------------------
I can not reproduce the issue from command line because for it to be
reproducable, I have to replace the UriResolver which I can do only if I embed
it.
As long as the datafile-resource in <fo:external-graphic
src="datafile://1/778940" width="14.85cm" height="10.5cm" />
is of a normal type, it workes fine but as soon as I try to embed a pdf, I get
the exception mentioned above.
Example fo:
<?xml version="1.0" encoding="utf-8"?>
<fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format";>
<fo:layout-master-set >
<fo:simple-page-master margin-left="1cm " page-width="21.00cm"
margin-right="1cm" margin-bottom="1cm " master-name="first" margin-top="2cm"
page-height="29.70cm" >
<fo:region-body />
</fo:simple-page-master>
</fo:layout-master-set>
<fo:page-sequence master-reference="first" id="id1" >
<fo:flow flow-name="xsl-region-body" >
<fo:block font-family="helvetica,arial,sans-serif" font-size="11pt"
text-align="start" >
<fo:external-graphic src="datafile://1/778940" width="14.85cm"
height="10.5cm" />
</fo:block>
</fo:flow>
</fo:page-sequence>
</fo:root>
My UriResolver:
package ch.xxx.io.datasource;
import java.math.BigDecimal;
import javax.xml.transform.Source;
import javax.xml.transform.TransformerException;
import javax.xml.transform.URIResolver;
import javax.xml.transform.stream.StreamSource;
import ch.xxx.db.persimpl.maindb.DATAFILE;
import ch.xxx.lang.XStringAnalyze;
public class DatafileURIResolver implements URIResolver {
/**
* Should be datafile://<groupid>/<datafile-id>
*/
public static final String PREFIX = "datafile://";
private URIResolver fallbackResolver;
/**
* @param fallbackResolver Usually the resolver that has been registered
before it was replaced by this
*/
public DatafileURIResolver(URIResolver fallbackResolver) {
this.fallbackResolver = fallbackResolver;
}
@Override
public Source resolve(String href, String base) throws TransformerException {
if (href.startsWith(PREFIX)) {
String strippedPrefix = href.substring(PREFIX.length());
return new StreamSource(pds.getInputStream());
}
return null;
//return fallbackResolver.resolve(href, base);
}
}
