Can you please post the relevant service code too? Might it be a
concurrency issue?

Hello,
If someone familiar with creating service clients with AXIOM,
please help!
I was checked for outgoing SOAP messages with http sniffer on
client requests to server and realized that some of them is
malformed by interleaving each other why other is empty. Sometimes
they become so twisted that even result = sender.sendReceive
(method); can't pass XML structure analyze phase and can't do the
request at all - exceptions thrown is very varied then, but all of
them indicates broken XML structure. How can this happen?
I didn't use any static objects in my code which can assign to the
same static variables and i checked content of outgoing OMElement -
it's always well-formed. Problem happen inside sendReceive method.
I suppose sendReceive method of sender object sometimes write to
same httpclient stream. How i can
avoid such interleaving?
Example of such broken request:
1 thread: <??xmxlml ..... (and so on)
while
2 thread is empty
but
3 thread's request is properly formed and passed
ServiceClient sender = new ServiceClient();
sender.setOptions(options);
result = sender.sendReceive(method);
very sorry for bad english.
With hope,
Daniil

Good day,
I'm using Axis2 1.4 with tomcat5.5 and created both service and
client from a scratch with AXIOM via HTTP port.
And they worked together like charm, just before i'm beggining to
put them under some load. Even when there is just 3 simultaneous
calls - one of my client threads written with AXIOM begins to throw
varied exceptions without any stack trace, like:
org.apache.axiom.om.OMException
or
org.apache.axiom.om.OMException:
javax.xml.stream.XMLStreamException: ParseError at [row,col]:[1,1]
Message: An invalid XML character (Unicode: 0x0) was found in the
comment.
or
com.sun.org.apache.xerces.internal.xni.XNIException: Scanner State
7 not Recognized
or
org.apache.axiom.om.OMException:
javax.xml.stream.XMLStreamException: ParseError at [row,col]:[1,1]
Message: Open quote is expected for attribute "{1}" associated with
an element type "name".
... and this happens not always, but approx. 1/3 times of 3
simultaneus threads starts.
Here is my code:
OMElement method = fac.createOMElement(new QName(chartName));
for(String key : keys){
OMElement value = fac.createOMElement(new QName
(key));
String mapvalue = ((String[]) params.get(key))[0];
value.addChild(fac.createOMText(value, mapvalue));
method.addChild(value);
}
Options options = new Options();
options.setTo(ApplicationProperties.targetEPRFinance);
options.setTransportInProtocol
(Constants.TRANSPORT_HTTP);
OMElement result = fac.createOMElement(new QName
("EmptyResult"));
System.out.println("Payload for service: " +
method.toString());
try {
ServiceClient sender = new ServiceClient();
sender.setOptions(options);
result = sender.sendReceive(method);
} catch (AxisFault e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
System.out.println("Result from service: " +
result.toString());
