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:
/*******************************************/
public final class StatisticsConstants {
public static final String GLOBAL_REQUEST_COUNTER =
"wso2wsf.GlobalRequestCounter";
public static final String GLOBAL_RESPONSE_COUNTER =
"wso2wsf.GlobalResponseCounter";
public static final String REQUEST_RECEIVED_TIME =
"wso2wsf.request.received.time";
public static final String RESPONSE_SENT_TIME =
"wso2wsf.response.sent.time";
private StatisticsConstants() {
}
}
/*******************************************/
these properties are used in the main class of the handler which the aim
is to compute the response time:
/*****************************************/
import org.wsf.common.statistics.StatisticsConstants;

public InvocationResponse invoke(MessageContext msgContext) throws

if (opctx != null) {
System.out.println("opctx != null");
MessageContext inMsgCtx =
opctx.getMessageContext(WSDLConstants.MESSAGE_LABEL_IN_VALUE);
if (inMsgCtx != null) {
System.out.println("inMsgCtx != null");
Object receivedTime =
inMsgCtx.getProperty(StatisticsConstants.REQUEST_RECEIVED_TIME);
if (receivedTime != null) {
long responseTime = System.currentTimeMillis()
-Long.parseLong(receivedTime.toString());
// Handle global reponse time

inMsgCtx.getParameter(StatisticsConstants.GLOBAL_REQUEST_COUNTER);
int globalReqCount = 0;

globalReqCounterParam.getValue()).getCount();
}
StatisticsModule.responseTimeProcessor.addResponseTime(responseTime,
globalReqCount, msgContext);

}
/*******************************************/
Concerning the class which take in charge tha addition of the response
time is ResponseTimeProcessor

/****************************************/
Remark: this is a simple try of a code which already exist at :
https://wso2.org/svn/browse/wso2/wsf/java/trunk/modules/statistics/src/main/java/org/wso2/wsf/common/statistics/module/?pathrev=281
Of course, i build the necessary files (as module.xml) and i generate
their byte code and finally i encapsulated them in a .mar archive to
test the module
when i engage it, i don't face any problem and the whole of the module
work properly, but the main object (received time) which all of the
class depend on are returned, always, as a null
hoping you can identify what i'm missing, i'll be so thankful
Best regards

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

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
