[Axis2] Problem in passing XML data as String parameter
Hi,
I am using a stub client generated from wsdl using axis wsdl2java. I am
trying to execute an operation with a string parameter. When I try to pass
some XML data fragment as string for that parameter, it gives me "HTTP
Transport error : '400' - 'Bad Request' " error. I looked at the SOAP
request being generated. The '<' character in the XML string that I passed
was modified into <. Now this happens, I believe, because the stub code
is using XMLStreamWriter.writeCharacters() on the XML string which doesn't
accept any such character in the string. Now I dont know how I should
resolve this problem. Is there anyway in which I can pass an XML data as
string parameter. I will appreciate any help.
Regards,
Satyajit

XML doesn't require the '>' character to be escaped, except in some
particular conditions (when following "]]"). I don't see anything wrong
with the escaping being done here.
From what you said, I'd suspect that the service really expects you to
use an <HTMLFragment> child element, as in Anne's second example. If
this is included in the schema the generated code should provide a way
to set this. Can you point us at the WSDL and schema?

The problem is that it's only partially escaping the fragment for you.
You want the message to read either:
<ns1:DeviceInfo><HTMLFragment>True</HTMLFragment></ns1:DeviceInfo>
(which is how it should be if you are sending the value as a string) or
<ns1:DeviceInfo><HTMLFragment>True</HTMLFragment></ns1:DeviceInfo>
(which is sending the data as XML)

Re: [Axis2] Problem in passing XML data as String parameter
Posted by Satyajit Jha <sa...@gmail.com>.
Hi Anne,
Thanks for your response.
I do believe that the problem is due to the reasons I mentioned. I will try
to provide a context here. I am using axis2 generated client stub for
accessing MS Reporting Service (MSRS) 2005 web service. I am trying to
render HTML reports using this and I am able to do that. Now I want
HTMLFragment (just the table, without html and body tag) from the report.
MSRS lets me do this by setting a parameter (DeviceInfo) of render operation
to "<HTMLFragment>True</HTMLFragment>". When I pass this value in
setDeviceInfo method of Render, I get following SOAP-body in my request
message.
<soapenv:Body><ns1:Render xmlns:ns1="
http://schemas.microsoft.com/sqlserver/2005/06/30/reporting/reportingservices
">
<ns1:Format>HTML4.0</ns1:Format>
<ns1:DeviceInfo><HTMLFragment>True</HTMLFragment></ns1:DeviceInfo>
</ns1:Render></soapenv:Body>
And this must be a bad request. Please let me know if you have any idea on
how to avoid this problem.
Thanks,
Satyajit

It depends on the characters in your data. Converting the '<' to
'<' is expected, but that's probably not what's causing your
problem. You might have characters in the document that can't be
properly escaped. If that's the case, you may not be able to send the
data as a string. Why not just send the XML data as XML data?
