Hi,
I am experiencing some a weird problem while trying to render some SVG.
I have a simple java program which reads in an XML file and an XSLT
stylesheet (containing some SVG) and render it out to PDF. What happens is
my terminal just frezzes, and I can't kill the process or do anything
else. The process only hangs when I run my application, i.e. if I run fop
from the command line passing it the XSLT with the SVG, it works fine.
Here is SVG from the XSLT style sheet:
<xsl:template name="DisplaySvg">
<fo:instream-foreign-object>
<svg:svg xmlns:svg="http://www.w3.org/2000/svg";
width = "300" height="200" viewBox="0 0 300 200"
xml:space="preserve">
<svg:g style="fill:white; stroke:#000000">
<svg:line x1="0" y1="200" x2="0" y2="0"/>
<svg:line x1="0" y1="200" x2="200" y2="200"/>
<svg:rect x="10" y="150" width="20" height="50"
style="fill:blue; stroke:#000000"/>
<svg:rect x="40" y="170" width="20" height="30"
style="fill:black; stroke:#000000"/>
<svg:rect x="70" y="100" width="20" height="100"
style="fill:green; stroke:#000000"/>
<svg:rect x="100" y="20" width="20" height="180"
style="fill:yellow; stroke:#000000"/>
<svg:rect x="130" y="150" width="20" height="50"
style="fill:red; stroke:#000000"/>
</svg:g>
</svg:svg>
</fo:instream-foreign-object>
</xsl:template>

The my java application which does what I explained above is:
import java.io.*;
// FOP libraries
import org.apache.fop.apps.Driver;
import org.apache.fop.apps.Version;
import org.apache.fop.messaging.MessageHandler;
import org.xml.sax.InputSource;
import org.apache.fop.apps.FOPException;
import org.apache.avalon.framework.logger.ConsoleLogger;
import org.apache.avalon.framework.logger.Logger;
import javax.xml.transform.*;
import javax.xml.transform.stream.*;
import javax.xml.transform.sax.*;
class RenderingEngineXsltSvg
{
// number of PDFs to be generated
static final int OUTPUT_SIZE = 1;
static final String INPUT_XML = "statement.xml";
static final String INPUT_XSLT = "toXslFoSVG.xslt";
static final String INPUT_DIR = "../../tmp/input/";
static final String OUTPUT_DIR = "../../tmp/output/";
public static void main(String args[])
{
try
{
// only create the Transformer which reads the XSLT once
Transformer transformer = TransformerFactory.newInstance()
.newTransformer(new StreamSource(INPUT_DIR + INPUT_XSLT));
for(int i = 1; i <= OUTPUT_SIZE; i++)
{
String fileName = INPUT_XML;
int fileLength = fileName.length();
fileName = fileName.substring(0, fileLength - 4);
String outFileName = OUTPUT_DIR + fileName + i + ".pdf";
Driver driver = new Driver();
driver.setOutputStream(new
FileOutputStream(outFileName));
Logger logger = new
ConsoleLogger(ConsoleLogger.LEVEL_INFO);
MessageHandler.setScreenLogger(logger);
driver.setLogger(logger);
driver.setRenderer(Driver.RENDER_PDF);
transformer.transform(new
StreamSource(INPUT_DIR + INPUT_XML),
new SAXResult(driver.getContentHandler()));
System.out.println("***** GENERATED PDF: " + i + "
*****");
}
}
catch (javax.xml.transform.TransformerConfigurationException ex)
{
System.err.println("Exception: " + ex.toString());
}
catch (javax.xml.transform.TransformerException ex)
{
System.err.println("Exception: " + ex.toString());
}
catch (IOException ex)
{
System.err.println("IO Exception: " + ex.toString());
}
// Everything is OK - exit
System.exit(0);
}
}

Any help would be appreciated.
