MessageContext.getProperty does not work
Hello
When I try to get a property from MessageContext it always returns null.
the instruction is below:
/****************************************************/
MessageContext inMsgCtx = opctx.getMessageContext("In");
if (inMsgCtx != null) {
Object receivedTime = inMsgCtx.getProperty(StatisticsConstants.REQUEST_RECEIVED_TIME);
if (receivedTime != null) {
System.out.println("receivedTime != null");
long responseTime = System.currentTimeMillis() - Long.parseLong(receivedTime.toString());
}
else
System.out.println("receivedTime = null");
/*************************************************/
_Remark :_
StatisticsConstants.REQUEST_RECEIVED_TIME
is a static final String defined in an other class "StatisticsConstants"
value :
REQUEST_RECEIVED_TIME = "wso2wsf.request.received.time";
please can some one help me

hi,
i think it's not possible to pass parameters from calling server/client to
any handlers (on the other hand, handlers can pass parameters between each
other e.g. handler1 sets a propertyA while handler2 which gets invoked as a
next one reads propertyA's value). Such parameters (defined on the client or
server side) are not part of SOAP message/envelope/headers hence you get
null while trying to read them.
I did some tests with Axis1 setting parameters as a part of invoking a
method on my stub class (... mystub._setProperty(..)). The only properties
available for me in handlers were those about username & password
i'm not an expert in axis1 or axis2 so I'd be grateful if someone with more
experience could shed some light on this issue (availability of user defined
parameters (defined inside client code or server code ) in handlers). I've
already seen many threads where people had been asking the very same
question but unfortunately nobody actually answering it.

Hi
i would be grateful for the response you sent to me
actually, all the properties figure in a an other class which the name
and the body are as follows:

Hi ,
in where you set the value for your property ...? can you provide
some codes to figure out your problem ..?
