Hi,
I think this can be done by System.setProperty(...), and I thought with:
System.setProperty( "org.xml.sax.driver", "org.apache.xerces.parsers.SAXParser" );
But I tried it and it does not work, maybe I did something wrong.
I tried another one, and the following should work:
System.setProperty( "javax.xml.parsers.SAXParserFactory",
"org.apache.xerces.jaxp.SAXParserFactoryImpl" );
Then you get a "org.apache.xerces.jaxp.SAXParserImpl" Parser.
If no property is set, the application uses the default parser: the first one it finds
in your classpath.
You can test it by your own, try the following with and without setting the System property:
// =========
import javax.xml.parsers.*;
public class ParserTest
{
public static void main(String[] argv)
throws Exception
{
System.setProperty( "javax.xml.parsers.SAXParserFactory",
"org.apache.xerces.jaxp.SAXParserFactoryImpl" );
SAXParserFactory factory = SAXParserFactory.newInstance();
SAXParser parser = factory.newSAXParser();
System.out.println("Parser Class: " + parser.getClass().getName());
}
}// ===========
Greetings,
Marko

I serched a little, and I found one difference between calling the fop.bat and processing servlet .
The fop.bat use
org.apache.xerces.parsers.SAXParser
while servlet code uses
oracle.xml.parser.v2.SAXParser
The library xmlparserv2.jar is necessary, without it whole JDeveloper won't run. All FOP libraries are in front of this library in my project, but servlet still uses parser from xmlparserv2.jar .
My question is this : Can I somehow choose, which parser (from which library) to use ? Some example would be welcomed. I am still a beginner in this field. Thanks.

I am trying to upgrade FOP from version 0.20.3 to 0.20.4 . I use Oracle's JDeveloper 9i
To my project I added all libraries, which I found in fop.bat :
fop.jar batik.jar xalan-2.3.1.jar xercesImpl-2.0.1.jar xml-apis.jar avalon-framework-cvs-20020315.jar logkit-1.0.jar
When I process my FO file by fop.bat, everything is ok. When I do this in servlet, following error appears:
[INFO]: building formatting object tree [INFO]: [1] - the logging stops here

Any suggestions what's wrong ? Thanks.
