Problem with calling WebService from serviceTask
*My goal is to call succesfully a WebService in activity process.I'm working
with Servicemix 5.0.0. I started with example
apache-servicemix-5.0.0/examples/activiti/activiti-camel , which I run
succesfully via features:install.Then I modified file OrderProcess.bpmn.xml
and the main process in it looks like below now:*
*I use the class WsDelegate I found as a sample to help calling WebService
from activiti process, and it looks like below:*package
org.apache.servicemix.examples.activiti; import java.util.ArrayList;import
java.util.StringTokenizer; import
org.activiti.engine.delegate.DelegateExecution;import
org.activiti.engine.delegate.Expression;import
org.activiti.engine.delegate.JavaDelegate;import
org.apache.cxf.endpoint.Client;import
org.apache.cxf.jaxws.endpoint.dynamic.JaxWsDynamicClientFactory;import
javax.xml.namespace.*;public class WsDelegate implements JavaDelegate {
private Expression wsdl; private Expression operation; private
Expression parameters; private Expression returnValue; public void
execute(DelegateExecution execution) throws Exception { String
wsdlString = (String)wsdl.getValue(execution);
JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance();
Client client = dcf.createClient(wsdlString); ArrayList paramStrings =
new ArrayList(); if (parameters!=null) { StringTokenizer st = new
StringTokenizer( (String)parameters.getValue(execution), ","); while
(st.hasMoreTokens()) { paramStrings.add(st.nextToken().trim());
} } Object response =
client.invoke((String)operation.getValue(execution),
paramStrings.toArray(new Object[0])); if (returnValue!=null) {
String returnVariableName = (String) returnValue.getValue(execution);
execution.setVariable(returnVariableName, response); } }}*I modified
example class ActivitiRouteBuilder and this is the code after
modification:*package org.apache.servicemix.examples.activiti; import static
org.activiti.camel.ActivitiProducer.PROCESS_KEY_PROPERTY; import
java.util.HashMap;import java.util.Map; import

= new Helper(); @Override public void configure() throws Exception {
/* * This route will start a new OrderProcess instance. Using the
PROCESS_KEY_PROPERTY, we are assigning a * business key to our

also * sending a Map containing additional variables to add to the

.setBody(bean(helper)) .setProperty(PROCESS_KEY_PROPERTY,
simple("file:name")) .to("activiti:OrderProcess")
.log("Process to handle incoming order file has been started (process
instance id ${body})"); /* * This route will notify a
running OrderProcess of an order delivery event. Here too, we are setting
the * PROCESS_KEY_PROPERTY to correlate the delivery message with
right order process instance. */
from("file:var/activiti-camel/delivery") .log("Notifying process
about delivery for order ${file:name}")
.setProperty(PROCESS_KEY_PROPERTY, simple("file:name"))
.to("activiti:OrderProcess:receiveDelivery"); /* * The BPMN
process can also trigger Camel routes as part of the process. In these
routes, the variables that * you added to the process are available
as Exchange properties. The next two routes will be triggered while
* processing the order and the order delivery. */
from("activiti:OrderProcess:processOrder") .log("Processing order
${property.orderid} created on ${property:timestamp}") .log("
original message: ${property.message}");
from("activiti:OrderProcess:processDelivery") .log("Processing
delivery for order ${property.orderid} created on ${property:timestamp}")
.log(" original message: ${property.message}"); } /* * A few
helper methods used for routing */ public static final class Helper {
/* * This method will extract information from the Exchange (using
Camel annotations) and put them in a * Map that will be used for
setting up the process' variables. */ @Handler public
Map getProcessVariables(Exchange exchange) { Message in =
exchange.getIn(); Map<String, Object> variables = new
HashMap<String, Object>(); variables.put("message", "pusto");
variables.put("orderid", in.getHeader("id"));
variables.put("timestamp", "teraz"); return variables; }
}}*And when I try to start the process through calling

Re: Problem with calling WebService from serviceTask
Posted by Krzysztof Sobkowiak <kr...@gmail.com>.
Hi Michal
Could you please provide a small complete sample? I have changed the
route as described in your email, but it works (I had to install the
camel-jetty) feature. You have implemented the class WsDelegate but you
have not written where do you use it - probably somewhere in the process
definition.
The stack trace says
Caused by: java.lang.ClassNotFoundException:
javax.xml.namespace.QNameat
In my opinion your bundle is missing the import of this package. If you look in one of the jaxws samples (e.g. cxf-osg), import of the package javax.xml.namespace is added to the maven bundle plugin configuration.
<Import-Package>
javax.jws,
javax.wsdl,
*javax.xml.namespace,*
org.springframework.beans.factory.config,
*
</Import-Package>
I think, you should add this (and perhaps some additional) packages into the import definition
Best regards
Krysztof
