Hi All,

I am new to servlet programming.

Calling servlet that is deployed in remote Apache Tomcat XP server. Standalone java works fine.
I am trying to call using message Broker from DEV machine, it gives me an error

MQInput---> JCN --->Trace

WMB7 on windows box

Here is the Java snippet:

Code:

private void geocode() throws MapMarkerException, MapMarkerFatalException {
      /* Set server url*/
      String url =
      "http://devserver:8090/mapmarker40/servlet/mapmarker";

      /* Input address example */
      String addr = "6 GLOBAL VIEW";
      String postcode = "12180";
      String city = "GOO";
      String state = "OZ";
       USA_UserInputAddress inpAddr = new USA_UserInputAddress();

      /* Set the input Address */
      inpAddr.setStreet(addr); /* 'street' */
      inpAddr.setCity(city); /* 'city' */
      inpAddr.setState(state); /* 'state' */
      inpAddr.setZipcode(postcode); /* ‘zipcode’ */

      USA_GeocodeConstraints geoCon = new USA_GeocodeConstraints();
      /* Geocode Constraints:
      * Review Java docs for a complete constraint list and
      * default values
      */

      geoCon.setMustMatchAddressNumber(true);
      geoCon.setMaxCandidates(1);
      geoCon.setReturnCloseCandidatesOnly(true);
      geoCon.setFallbackToPostal(false);
      //USA_UserCandidateAddress canAddr = null;

      /*USA_UserInputAddress inpAddr = new USA_UserInputAddress();

      /* Geocode Address */
      ClientGeocodeResponse geoRes =
MMJClient.geocode
(MapMarkerJavaAPI.GEOCODE_TYPE_ADDRESS,inpAddr,geoCon,url);
      /*Get candidate count*/
      int candCount = geoRes.candidateCount();



here is the trace:

I have sourced all clinet jar files in the below windows directories

\Classes
\jre16\lib\ext

Based on the trace message, I did make sure that jdom.jar file is in the above directories. There is an encoding-map.xml file which I placed in below directory,

\Classes
\jre16\lib
\jre16\lib\ext
\exmltconfig\etc

I have included encoding-map.xml in bar and deployed it as well.

Here is the env,

Code:

Environment variable C:\Program Files\IBM\MQSI\7.0\messages;C:\Program Files\IBM
\MQSI\7.0\classes;C:\Program Files\IBM\WebSphere MQ\Java\lib\connector.jar;C:\Pr

Any help!!!

You need to look up where on Windows the broker looks for 3rd party jar files to be placed so that JCN's can use them.

Or include the 3rd party jars in your bar file(s).

Why oh why why why aren't you using an HTTPRequest node?

It worked using HTTPRequest Node. But I am curious to know why it did not work in JCN.

Let me do more analysis.

3rd party Jar files used by broker can be put in $MQSI_WORKPATH/shared-classes. On Windows, this would be

Code:

C:\Documents and Settings\All Users\Application Data\IBM\MQSI\shared-classes
