Thomas Mayr commented on AXIS-2153:
-----------------------------------
Below the full code of the method
org.apache.axis.message.MessageElement.getValue() .
The assignments to textClassName and nodeClassName are only for debug purposes:
public String getValue() {
/*--- Fix for AXIS-1817
if ((recorder != null) && (!_isDirty)) {
StringWriter writer = new StringWriter();
TextSerializationContext outputContext =
new TextSerializationContext(writer);
try {
recorder.replay(startEventIndex,
endEventIndex,
new SAXOutputter(outputContext));
} catch (Exception t) {
log.debug("getValue()", t);
return null;
}
String value = writer.toString();
return (value.length() == 0) ? null : value;
}
---*/
if (textRep != null) {
// weird case: error?
return textRep.getNodeValue();
}
if (objectValue != null) {
return getValueDOM();
}
String textClassName = Text.class.getPackage().getName() + "." +
Text.class.getName ();
String nodeClassName = Node.class.getPackage().getName() + "." +
Node.class.getName ();
for (Iterator i = getChildElements (); i.hasNext ();)
{
org.apache.axis.message.NodeImpl n =
(org.apache.axis.message.NodeImpl) i.next ();
if (n instanceof org.apache.axis.message.Text)
{
org.apache.axis.message.Text textNode =
(org.apache.axis.message.Text) n;
return textNode.getNodeValue ();
}
}
return null;
}

> Key: AXIS-2153
> URL: http://issues.apache.org/jira/browse/AXIS-2153
> Project: Apache Axis
> Type: Bug
> Versions: 1.2.1
> Environment: SAP WAS 6.40 Application Server on Windows 2000 SP4
> Reporter: Thomas Mayr
> Priority: Critical
>
> I don't know exactly why, but the method
> org.apache.axis.message.MessageElement.getValue() always returns null,
> although the message array of the iterator contains the right element of
> type Text with the right value. After I patched the last for loop in the
> following way it works:
> for (Iterator i = getChildElements(); i.hasNext(); ) {
> org.apache.axis.message.NodeImpl n =
> (org.apache.axis.message.NodeImpl) i.next();
> if (n instanceof org.apache.axis.message.Text)
> {
> org.apache.axis.message.Text textNode =
> (org.apache.axis.message.Text) n;
> return textNode.getNodeValue();
> }
> }
> As you can see I casted the element returned by the method i.next() with the
> full qualified class path and call the method getNodeValue() also with an
> object casted with the full qualified class path
> (org.apache.axis.message.Text). After this patch the correct method
> Text.getNodeValue() is called. Previousely this method wasn't called and I
> could not step in this method with the eclipse debugger! As I said, I don't
> understand what's exactly going on but I''ll leave this analysys to the
> developer ;-)
> Best regards Thomas Mayr
