would be the correct Java form. CDATA is an XML construct, not a Java
construct.

thanks - don't know whether you have heard of it, but we are uisng a
product called laszlo and even though the xml i return is perfect when i
write a java client to my web service when laszlo is used it escapes the
angle brackets - we have now found out xml isn't supported!
so now i have to re-write my ws
i have this code which returns the xml
StringWriter writer = new StringWriter();
// create a resultsetbuilder to transform resultset to XML
try
{
RecordsetToXML rsXML = new RecordsetToXML(rs, "ROOT", "RECORD");
// create the XML from recordset
Document jDOMDoc = rsXML.build();
rs = null;
XMLOutputter outputter = new XMLOutputter();
outputter.output(jDOMDoc, writer);
result = writer.toString();
//System.out.print("XML " + writer);
writer.close();
}
.......
return result;
So do i do this - [CDATA[writer.toString()]]
when i'm testing i do String ret - (String) call.invoke(new
Object[]{params}); as normal
thanks for your help

CDATA like this: instead of
String s = "<someXmlStructure>...</someXmlStructure>";
put
String s = "<![CDATA[<someXmlStructure>...</someXmlStructure>]]>";
in the string that you return from your service implementation. This makes the
return message something like
<soap:envelope>
<soap:body>
<xsd:string>
<![CDATA[<someXmlStructure>...</someXmlStructure>]]>
</xsd:string>
</soap:body>
</soap:envelope>
See
http://www.w3schools.com/xml/xml_cdata.asp
for more details and examples.
However, doing it that way is against the spirit of SOAP. You should really
have your someXmlStructure directly in the body of the message:
<soap:envelope>
<soap:body>
<someXmlStructure>...</someXmlStructure>
</soap:body>
</soap:envelope>
If you mapped someXmlStructure to SomeJavaClass using WSDL2Java, then you
could return an instance of SomeJavaClass from your service implementation and
Axis would serialize it into the required XML. If you want to generate your
someXmlStructure as a DOM, then you might be able to get that serialized;
check out the SAAJ spec. (Anybody have a succint example of returning a DOM
from a service implementation?) I don't think Axis has a way to accept
serialized XML from a service implementation; i.e. you can't write out
text-with-angle-brackets and have Axis include it literally in the return
message, other than the XML-in-a-string trick that you've already found.
Cheers,
Guy

Re: xml with strange characters

hi
i'm returning the xml as a result of call.invoke. when i write a test
client using java the xml is well frmed, however we are also usg an
application called laszlo, but when you get the same xml using laszlo that's
whe it comes back with the &alt for the angle brackets
would it be possible to lead me to an example of cdata and sending the xml
as the body of the message (i think this is what i'm doing but just want to
make sure)
thanks for your help

Re: xml with strange characters
Posted by Guy Rixon <gt...@ast.cam.ac.uk>.
If I understand you correctly, you're putting data marked up as XML in a
string and then sending that string as an XML element in a SOAP message. In
this usage, Axis has to turn the angle brackets into entity references in
order to make the XML well-formed; you're not allowed to have literal angle
brackets in the value of an XML element.
If you desparately need to send your XML structure as the value of
some XML element, then you can wrap it in a CDATA section so that Axis need not mess
with the angle brackets. However, why not just send the XML as the body of the
message (normal document/literal style)?

it's not - when the client receives the xml it has &alt instead of < or >
Also when i test my service get the same characters in the soap message

Why is it a problem ?
Axis should deserialize this message correctly on the client side...
