java.lang.ClassCastException: com.sun.org.apache.xerces.internal.dom.DocumentImpl cannot be cast to org.w3c.dom.Element

[jlc488]

public Distribution createPrivateDistribution(String originBucketName,
String callerReference, String[] CNAME, String comment,
boolean distributionTogle, LoggingStatus loggingStatus,
String originAccessIdentityId, boolean trustedSignerSelf,
String[] trustedSignerAwsAccountNumbers) {
Distribution distribution = null;

try {
distribution = cloudFrontService.createDistribution
(originBucketName, callerReference, CNAME, comment, distributionTogle,
loggingStatus, originAccessIdentityId, trustedSignerSelf,
trustedSignerAwsAccountNumbers);
} catch (CloudFrontServiceException e) {
e.printStackTrace();
}
log.debug("New Private Distribution: " + distribution);
return distribution ;
}

above is the simple code snippet and I am getting an exception where
the line of fetching createDistribution method.

I am sending originBucketName & originAccessIdentityId only, rest
variables are set to null.

And I am getting an exception as

java.lang.ClassCastException:
com.sun.org.apache.xerces.internal.dom.DocumentImpl cannot be cast to
org.w3c.dom.Element

any ideas or suggestions would be appreciated.

Thanks in advance.

I don't know why though, but I've found out the solution to this
problem.

I've changed the library from java-xmlbuilder-0.3.jar(added by maven
setting) to java-xmlbuilder-2.jar(added by eclipse) and this exception
will be resolved.

Any ideas why?

Thanks guys

Hmm, this is an odd problem.

The XmlBuilder library is actually another thing I wrote and I don't recall making any tangible change to the way that documents are built between versions 2 and 3. In my experience XML library issues are a frequent and frustrating problem with Java.

Do you happen to have a full stack trace for the java.lang.ClassCastException ?

In any event, you are better off using the newer version of this library so hopefully you won't see any more of these problems.

Regards,
James
