[Betwixt] Betwixt and Log4j
Hello,
My setup:
Java: Sun SDK, java version "1.4.2-beta"
Betwixt: 1.0 apha1
Digester: 1.5
Log4j: 1.2.8
The code attached reproduces the problem.
Running the attached code produce the expected result, i.e.
the outside tag is renamed to 'product' and the 'archives'
field is ignore:
<product>
<id>1</id>
<name>Productname</name>
</product>
Turning debugging on to 'DEBUG' level in log4j.properties
generates the following output (as well has the
stack exception thrown by XMLIntrospectorHelper):
<ProductXMLTest>
<archives>
<archive>
<id>2</id>
<name>ArchiveName</name>
</archive>
</archives>
<id>1</id>
<name>Productname</name>
</ProductXMLTest>
Obviously this is not the right output (e.g. 'archives'
should be hidden). This is probably due to the exception
thrown by Betwixt. Am I missing something?

You probably should wait till I fix/investigate some pending issues

Not a problem, an easy work around for me was to turn debug to
FATAL for all Betwix packages. I'll grab the CVS HEAD code if/when
I get a chance.

Sorry for the verrry late answer...
Got swamped with personal problems and a huge workload at the office..
sorry.. Finally got my betwixt evening though :)
I've been trying to reproduce your problem, with debug level turned on.
It turns out that you must be using betwixt 1.0 ALPHA 1.. The bug was
fixed a month after the release (even by myself). If you use cvs head
you should be without any problems. (the code snippet you pasted also
got me doubting it was the correct code for your version, since an npe
is actually prevented in the descriptor!=null line..
Hope this helps and is not too late :(
Mvgr,
Martin

To answer my own question, I believe the error comes
from XMLIntrospectorHelper.java, around line 488 (latest
from CVS):
...
ElementDescriptor descriptor =
findGetCollectionDescriptor(
introspector,
rootDescriptor,
propertyName );
if ( log.isDebugEnabled() ) {
log.debug( "!! " + propertyName + " -> " + descriptor );
log.debug( "!! " + name + " -> "
+ (descriptor!=null?descriptor.getPropertyName():"") );
}
if ( descriptor != null ) {
...
If 'descriptor' is null and debugging turned on, a NullPointer
Exception will be raised. The debug message should go in the
following if block.
