[jira] [Created] (AXIOM-442) Null pointer exception in MTOM
validation
James Grahn created AXIOM-442:
---------------------------------
Summary: Null pointer exception in MTOM validation
Key: AXIOM-442
URL: https://issues.apache.org/jira/browse/AXIOM-442
Project: Axiom
Issue Type: Bug
Affects Versions: 1.2.12
Reporter: James Grahn
As part of an Axis2 workflow, my code validates incoming messages against schemas. This seems to work in all cases except when the incoming message contains an MTOM attachment.
The code constructs a Source object for the part of the message to be validated, then calls the "validate" method on a properly constructed javax.xml.validation.Validator object:
Source validateMe = new OMSource(messagePart);
validator.validate(validateMe);
The error generated looks like this:
java.lang.NullPointerException
at org.apache.axiom.om.impl.llom.OMTextImpl.getTextCharacters(OMTextImpl.java:272)
at org.apache.axiom.om.impl.serialize.OMXMLReader.generateEvents(OMXMLReader.java:196)
at org.apache.axiom.om.impl.serialize.OMXMLReader.generateEvents(OMXMLReader.java:166)
at org.apache.axiom.om.impl.serialize.OMXMLReader.generateEvents(OMXMLReader.java:163)
at org.apache.axiom.om.impl.serialize.OMXMLReader.parse(OMXMLReader.java:83)
at org.apache.axiom.om.impl.serialize.OMXMLReader.parse(OMXMLReader.java:73)
at org.apache.xerces.jaxp.validation.ValidatorHandlerImpl.validate(Unknown Source)
at org.apache.xerces.jaxp.validation.ValidatorImpl.validate(Unknown Source)
at javax.xml.validation.Validator.validate(Unknown Source)
----
By the time it reaches my handler, I'm not fully certain what should be in the MTOM attachment element should contain, as it's reasonable to assume that the attachment has been extracted by then. A NullPointerException doesn't seem appropriate, however.
A logging statement does show the attachment inline, encoded in Base64 (though I believe all incoming MTOM is represented that way if the envelope is printed for a log).

[jira] [Updated] (AXIOM-442) Null pointer exception in MTOM
validation
Posted by "Andreas Veithen (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/AXIOM-442?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Andreas Veithen updated AXIOM-442:
----------------------------------
Component/s: LLOM
DOOM
Affects Version/s: 1.2.13
Assignee: Andreas Veithen
Based on inspection of the relevant code, the issue still exists in trunk. It affects both LLOM and DOOM.
getTextCharacters indeed fails to consider the case where the text node is backed by a DataHandler, resulting in a NullPointerException.
The other issue is that using getTextCharacters is the worst way to pass base64 encoded binary data to a SAX ContentHandler. There are better ways to do that (where better means better performance and constant memory usage).
