without this particular file, though I don’t feel right just pulling it out of
Karaf blindly, as its absence creates a distinct possibility of unforeseen
issues down the road.
Here are the only imports my bundle references in its manifest:
Import-Package:
javax.xml.transform,javax.xml.transform.stream,org.xml.sax,javax.xml.parsers,javax.xml.validation
There are no entries under Bundle-Classpath
Lastly, here is the java code that performs the xml parsing:
DocumentBuilderFactory factory =
DocumentBuilderFactory.newInstance();
SchemaFactory sf =
SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
Schema schema = sf.newSchema(new StreamSource(new
FileInputStream("")));
factory.setNamespaceAware(true);
factory.setSchema(schema);
factory.setExpandEntityReferences(false);
factory.setXIncludeAware(false);
factory.setFeature("http://xml.org/sax/features/external-parameter-entities",false);
factory.setFeat
Re: Karaf 4.2.10 - NullPointerException during xml parsing
Hi Brock,
Maybe you have xerces installed as bundle in your distribution ?
It sounds like a version mismatch.
Can you share the bundles installed ?
Thanks,

JB

Karaf 4.2.10 - NullPointerException during xml parsing

After snooping around, I noticed a

containing parser-related libs. My code executed successfully once I ran Karaf
without this particular file, though I don’t feel right just pulling it out of

Please advise me as to what I am doing wrong, as well as a possible solution.
Thank you for your time!
