hi all,
i have written a J2ME client that, using ksoap, sends XML request

in the servlet (running on JBoss), i am trying to parse the XML request using
AXIS 1.1, but the code keeps on giving me a null pointer exception when i try
to read the content of the message.
Hi Marco,
the message syntax seems correct.
Did you already try to generate the same message using Axis in order to see if
there are any significant differences and/or if Axis is able to read the same
message when generated using Axis?
Best,
Stefan
here is the message
<v:Envelope xmlns:i="http://www.w3.org/1999/XMLSchema-instance";
xmlns:d="http://www.w3.org/1999/XMLSchema";
xmlns:c="http://schemas.xmlsoap.org/soap/encoding/";
xmlns:v="http://schemas.xmlsoap.org/soap/envelope/";>
<v:Header />
<v:Body>
<n0:agency id="o0" c:root="1" xmlns:n0="http://www.tgmm.com/agenciesdemo";>
<name i:type="d:string">testagency</name>
<tel i:type="d:string">12234</tel>
<email i:type="d:string">tgmm@xxxxxxxxx</email>
<contacted i:type="d:string">01012003</contacted>
<contactperson i:type="d:string">Myself</contactperson>
</n0:agency>
</v:Body>
</v:Envelope>
the code for retrieving it is as follows
Enumeration enumeration = request.getHeaderNames();
MimeHeaders mimeHeaders = new MimeHeaders();
while (enumeration.hasMoreElements()) {
String string1 = (String)enumeration.nextElement();
String string2 = request.getHeader(string1);
mimeHeaders.addHeader(string1, string2);
}
System.err.println("Now instantianting message..");
MessageFactory factory = MessageFactory.newInstance();
SOAPMessage message = factory.createMessage(mimeHeaders, stream);
System.err.println("OK GOT THE MESSAGE..");
SOAPPart soapPart = message.getSOAPPart();
System.err.println("OK GOT THE PART..");
SOAPEnvelope envelope = soapPart.getEnvelope();
and the output is this (showing the exception when i try to retrieve the
envelope..)
13:25:10,927 ERROR [STDERR] Now instantianting message..
13:25:10,977 ERROR [STDERR] OK GOT THE MESSAGE..
13:25:10,977 ERROR [STDERR] OK GOT THE PART..
13:25:11,007 ERROR [STDERR] Exception in reading stream: java.lang.NullPointerEx
ception
If i write my own PullParser that is just looking for the agency etc tags, it works fine
so it looks like AXIS and ksoap cannot talk to each other...
is there a solution for parsing SOAP messages sent by ksoap client?
thanx in advance and regards

Subject: help in parsing soap messages
hi all,
i am fairly new to ksoap. i have written 'two way' xml
communication
between a J2ME app (midp toolkit 2.0) and a serverside app
implemented with struts
on jboss.
so far, i have been using my own xml format,but now i want to
move to SOAP.
writing SOAP from J2ME to serverside logic works fine, but
now i have the problem
of parsing the SOAP request.
i have tried to use ksoap for parsing this simple XML
<?xml version="1.0"?>
<SOAP-ENV:Envelope
xmlns:SOAP-ENV="http://www.w3.org/2001/12/soap-envelope";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xmlns:xsd="http://www.w3.org/2001/XMLSchema";>
<SOAP-ENV:Body>
<agencies>
<agency>
<name>name1</name>
<tel>1234</tel>
</agency>
</agencies>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
i have followed what was said in previous email to have a
look at SOAPEnvelope to see
how to parse it.
So, i copied the code from SOAPEnvelope and tried to
customize for my own needs, using
a the xml pullparser.
but for some reason i keep on getting following exception
Creating new AgencyImpl..
Exception in thread "main"
org.xmlpull.v1.XmlPullParserException: expected: END_
TAG {http://www.w3.org/2001/12/soap-envelope}Body
(position:START_TAG <agency> @
7:13)
at org.kxml2.io.KXmlParser.exception(KXmlParser.java:228)
at org.kxml2.io.KXmlParser.require(KXmlParser.java:1261)
at com.tgmm.commons.SoapParser.parse(Unknown Source)
at com.tgmm.commons.SoapParser.main(Unknown Source)
i cannot figure out what's wrong. the XML seems ok, since i
can see it in IE 5.5
i can attach the code that i am using.... if anyone can help
me in figuring out where is the problem.
with best regards
marco
