Juan Carlos Román commented on CXF-4942:
----------------------------------------
Hi Aki... sorry for the delayed response.
The answer is yes CDataXMLStreamWriter is a part of the interceptor, here is
the source:
{code:title=CdataWriterInterceptor.java}
package com.pagosonline.ppp4.banking.api.webservices.interceptors;
import java.io.OutputStream;
import javax.xml.stream.XMLStreamWriter;
import org.apache.cxf.interceptor.BareOutInterceptor;
import org.apache.cxf.interceptor.Fault;
import org.apache.cxf.message.Message;
import org.apache.cxf.phase.AbstractPhaseInterceptor;
import org.apache.cxf.phase.Phase;
import org.apache.cxf.staxutils.StaxUtils;
public class CdataWriterInterceptor extends AbstractPhaseInterceptor<Message> {
public CdataWriterInterceptor() {
super(Phase.WRITE);
addBefore(BareOutInterceptor.class.getName());
}
@Override
public void handleMessage(Message message) throws Fault {
// disable the XML character encoding
message.put("disable.outputstream.optimization", Boolean.TRUE);
XMLStreamWriter writer = StaxUtils.createXMLStreamWriter(message
.getContent(OutputStream.class));
message.setContent(XMLStreamWriter.class, new
CDataXMLStreamWriter(writer));
}
}
{code}
{code:title=CDataXMLStreamWriter.java}
package com.pagosonline.ppp4.banking.api.webservices.interceptors;
import javax.xml.stream.XMLStreamException;
import javax.xml.stream.XMLStreamWriter;
import org.apache.cxf.staxutils.DelegatingXMLStreamWriter;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
public class CDataXMLStreamWriter extends DelegatingXMLStreamWriter {
/** The logger class */
private static final Logger LOGGER =
LoggerFactory.getLogger(CDataXMLStreamWriter.class);
public CDataXMLStreamWriter(XMLStreamWriter del) {
super(del);
}
@Override
public void writeCharacters(String text) throws XMLStreamException {
boolean useCData = checkIfCDATAneeded(text);
if (useCData) {
LOGGER.info("WritingCData" + text);
super.writeCData(text);
}
else {
super.writeCharacters(text);
}
}
private boolean checkIfCDATAneeded(String text) {
if (text.contains("<")) {
return true;
}
return false;
}
public void writeStartElement(String prefix, String local, String uri)
throws XMLStreamException {
super.writeStartElement(prefix, local, uri);
}
}
{code}
Basically this code envelops the outbound message in a CDATA tag (I found this
source on the web, I don't know if there are a better way...).
Unfortunately I can't reproduce this error because appears very occasionally. I
attach the WSDL file and the sample message... hope that helps.
Thanks,
Juan
