This is a known problem with xmlbeans and axis2. Since Axis2 uses AXIOM to
convert the XML Bean Object, conversion has to happen in 2 places. The First
Place itself is when using XMLBeans
XMLBeans:
In XMLBeans there are 2 settings that have to happen they are
XmlOptions xmlOptions = new XmlOptions();
xmlOptions.setSaveCDataEntityCountThreshold(-1);
xmlOptions.setSaveCDataLengthThreshold(3);
xmlOptions.setSaveCDataLengthThreshold(3) --> make sure that the value set
here is a value which is less than the length of your cdata string (say is
your string has 10 chars at a min make sure that you set this value to 3 or
5
The next important step is you have to make sure that this options is passed
to the xmlText method , make sure that your XML Beans Object say for ex if
your response document is
com.samplecdataservice.cdataservice._2011.CdataResponseDocument when you
invoke the xmlText on this object the xmlOptions has to be passed, otherwise
it will not work
The next step is Axiom which again converts the CDATA to encode it , in
order to fix that i had to change the in-out class which is generated by
Axis to take this implementation
private org.apache.axiom.soap.SOAPEnvelope toEnvelope(
org.apache.axiom.soap.SOAPFactory factory,
com.samplecdataservice.cdataservice._2011.CdataResponseDocument param,
boolean optimizeContent) throws
org.apache.axis2.AxisFault {
org.apache.axiom.soap.SOAPEnvelope envelope = factory
.getDefaultEnvelope();
if (param != null) {
//envelope.getBody().addChild(toOM(param,
optimizeContent));
XmlOptions xmlOptions = new XmlOptions();
xmlOptions.setSaveCDataEntityCountThreshold(-1);
xmlOptions.setSaveCDataLengthThreshold(3);
ByteArrayInputStream bais = new
ByteArrayInputStream(param.xmlText(xmlOptions).getBytes());
XMLInputFactory xmlInputFactory =
XMLInputFactory.newInstance();
xmlInputFactory.setProperty(XMLInputFactory.IS_COALESCING,
Boolean.FALSE);
try {
StAXOMBuilder omBuilder = new
StAXOMBuilder(xmlInputFactory.createXMLStreamReader(bais));
envelope.getBody().addChild(omBuilder.getDocumentElement());
} catch (XMLStreamException e) {
// TODO Auto-generated catch block
e.printStackTrace();
createAxisFault(e);
}
//XMLInputFactory inputFactory =
XMLInputFactory.newInstance();
//inputFactory.c
//envelope.getBody().addChild((org.apache.axiom.om.OMElement)param.getDomNode());
}
return envelope;
}
The line
xmlInputFactory.setProperty(XMLInputFactory.IS_COALESCING, Boolean.FALSE);
is very important because Stax parser is defaulted to using COALESCING which
will remove the CDATA sections, in order to preserve it you need to set it
to false as shown above
