Hi everybody, I'm new to this list so bear with me...
It started off as one problem, but when I was trying to create a bug report
for the first I discovered a second. They both occur between lines 381 and
394 of org/apache/cocoon/serialization/AbstractTextSerializer.java.
The second problem is easier to recreate, so I'll cover it first. The result
is this:
java.lang.NullPointerException
at
org.apache.cocoon.serialization.AbstractTextSerializer$NamespaceAsAttributes.startElement(AbstractTextSerializer.java:386)
at
org.apache.cocoon.xml.AbstractXMLPipe.startElement(AbstractXMLPipe.java:88)
at
org.apache.xalan.transformer.ResultTreeHandler.flushElem(ResultTreeHandler.java:856)
Here is a simple XML file that causes the problem:
<page xmlns="foo">
<test xmlns="">
this is a test
</test>
</page>
and the offending code (in AbstractTextSerializer.java):
boolean found = false;
for (int attr = 0; attr < attrCount; attr++) {
if (qName.equals(attrs.getQName(attr))) {
// Check if mapping and attribute URI match
///*** uri is null here ***///
if (! uri.equals(attrs.getValue(attr))) {
getLogger().error("URI in prefix mapping and attribute do not
match : '" + uri + "' - '" + attrs.g
throw new SAXException("URI in prefix mapping and attribute do
not match");
}
found = true;
break;
}
}
In my sitemap.xmap, I have:
<map:match pattern="the-test-page.xml">
<map:generate type="file" src="{0}"/>
<map:serialize type="xml"/>
</map:match>
The other error is prooving really hard for me to reproduce with a
minimalized example. I do know that it is caused when I do a transformation
with Xalan using something like:
<stylesheet version="1.0" xmlns="http://www.w3.org/1999/XSL/Transform";>
...
<element name="foo" namespace="">...</element>
...
</stylesheet>
I think it might be that Xalan is sending a startPrefixMapping() for the
<stylesheet> or other XSL elements, and this is confusing the serializer when
it gets to the <element namespace=""/>. If I replace <element name="foo"
namespace=""/> with <foo xmlns=""/>, it works fine.
The error is the SAXException("URI in prefix mapping and attribute do not
match") from the code above, and the log message is:
URI in prefix mapping and attribute do not match :
'http://www.w3.org/1999/XSL/Transform' - 'http://www.w3.org/2000/xmlns/'
which is why I believe Xalan is confusing the serializer, since the
XSL/Transform namespace is never output by my stylesheet.
Sorry I can't help to recreate this one further. Thanks for your help!
