Problem with deployment of bar-archives

[mtf]

Hi all,

currently I am trying to deploy a process to the activiti engine running on tomcat, but something seems to be missing.
My current configuration is the demo-setup running on ubuuntu with JDK 1.6.

In the eclipse-editor I have added a user-library ACTIVITI_LIB to have a reference to the required libs (libs-runtime, libs-test)

The process file:

<definitions xmlns="http://www.omg.org/spec/BPMN/20100524/MODEL"   xmlns:activiti="http://activiti.org/bpmn"   targetNamespace="http://activiti/tests/javaCall">   <process id="SimpleJavaCall" name="Simple Java Call">      <startEvent id="startevent" name="Start"></startEvent>      <serviceTask id="javaCall"  name="My Java Task"              activiti:class="test.service.call.SimpleServiceToUpperCase" />      <sequenceFlow id="flow4" name="" sourceRef="startevent"         targetRef="javaCall"></sequenceFlow>      <sequenceFlow id="flow5" name="" sourceRef="javaCall"         targetRef="endevent"></sequenceFlow>      <endEvent id="endevent" name="End"></endEvent>   </process></definitions>‍‍‍‍‍‍‍‍‍‍‍‍‍‍

The java class:

package test.service.call;import org.activiti.engine.delegate.DelegateExecution;import org.activiti.engine.delegate.JavaDelegate;public class SimpleServiceToUpperCase implements JavaDelegate {   private static final String VARIABLE_NAME = "input";   public void execute(DelegateExecution execution) {      String var = (String) execution.getVariable(VARIABLE_NAME);      var = var.toUpperCase();      execution.setVariable(VARIABLE_NAME, var);   }}‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Using the generated JUnit-test, the execption is:

Error while closing command contextjava.lang.NullPointerException   at test.service.call.SimpleServiceToUpperCase.execute(SimpleServiceToUpperCase.java:12)   at org.activiti.engine.impl.bpmn.JavaDelegateDelegate.execute(JavaDelegateDelegate.java:48)   at org.activiti.engine.impl.bpmn.JavaDelegateDelegate.execute(JavaDelegateDelegate.java:39)   at org.activiti.engine.impl.bpmn.ClassDelegate.execute(ClassDelegate.java:96)‍‍‍‍‍‍‍

The deployment is succsessful and the process is shown in the activiti-explorer as well.
The (important part) of my deployment-descriptor (ant-script):
- copying the jar (containing the java class) into $path$/activiti-5.2/apps/apache-tomcat-6.0.29/webapps/activiti-rest/WEB-INF/lib (the same folder where also activiti-engine-5.2.jar, … are placed).
- using a copy of the activiti.cfg.xml in "activiti-cfg.jar"

<taskdef name="deploy-bar" classname="org.activiti.engine.impl.ant.DeployBarTask">         <classpath>            <pathelement path="src/main/config" />            <fileset dir="libs-runtime" />            <fileset dir="libs-test" />         </classpath>      </taskdef>‍‍‍‍‍‍‍

But if I start an instance I get the following exception in the logs:

ERROR [extensions.webscripts.AbstractRuntime] Exception from executeScript - redirecting to status template error: 01030001 Wrapped Exception (with status template): nullorg.springframework.extensions.webscripts.WebScriptException: 01030001 Wrapped Exception (with status template): null   at org.springframework.extensions.webscripts.AbstractWebScript.createStatusException(AbstractWebScript.java:742)   at org.springframework.extensions.webscripts.DeclarativeWebScript.execute(DeclarativeWebScript.java:167)   at org.springframework.extensions.webscripts.PresentationContainer.executeScript(PresentationContainer.java:69)   at org.springframework.extensions.webscripts.AbstractRuntime.executeScript(AbstractRuntime.java:333)   at org.springframework.extensions.webscripts.AbstractRuntime.executeScript(AbstractRuntime.java:189)   at org.springframework.extensions.webscripts.servlet.WebScriptServlet.service(WebScriptServlet.java:118)   at javax.servlet.http.HttpServlet.service(HttpServlet.java:717)   at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290)   at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206)   at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:233)   at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191)   at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127)   at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102)   at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109)   at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:298)   at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:857)   at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:588)   at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:489)   at java.lang.Thread.run(Thread.java:662)Caused by: java.lang.NullPointerException   at test.service.call.SimpleServiceToUpperCase.execute(Unknown Source)   at org.activiti.engine.impl.bpmn.JavaDelegateDelegate.execute(JavaDelegateDelegate.java:48)   at org.activiti.engine.impl.bpmn.JavaDelegateDelegate.execute(JavaDelegateDelegate.java:39)   at org.activiti.engine.impl.bpmn.ClassDelegate.execute(ClassDelegate.java:96)   at org.activiti.engine.impl.pvm.runtime.AtomicOperationActivityExecute.execute(AtomicOperationActivityExecute.java:40)   at org.activiti.engine.impl.interceptor.CommandContext.performOperation(CommandContext.java:62)…………..   at org.activiti.engine.impl.interceptor.CommandContextInterceptor.execute(CommandContextInterceptor.java:37)   at org.activiti.engine.impl.interceptor.LogInterceptor.execute(LogInterceptor.java:33)   at org.activiti.engine.impl.RuntimeServiceImpl.startProcessInstanceById(RuntimeServiceImpl.java:69)   at org.activiti.rest.api.process.ProcessInstancePost.executeWebScript(ProcessInstancePost.java:49)   at org.activiti.rest.util.ActivitiWebScript.executeImpl(ActivitiWebScript.java:68)   at org.springframework.extensions.webscripts.DeclarativeWebScript.execute(DeclarativeWebScript.java:64)   … 17 more‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

I also have tried it with a script-task (groovy), which runs without problems using the generated JUnit-test case, but deploying it in the same way like stated above (without creating the jar for the java class) the follwoing exceptions occur:

ERROR [extensions.webscripts.AbstractRuntime] Exception from executeScript - redirecting to status template error: 01030002 Wrapped Exception (with status template): org/activiti/engine/impl/scripting/ExecutionBindingsorg.springframework.extensions.webscripts.WebScriptException: 01030002 Wrapped Exception (with status template): org/activiti/engine/impl/scripting/ExecutionBindings   at org.springframework.extensions.webscripts.AbstractWebScript.createStatusException(AbstractWebScript.java:742)   at org.springframework.extensions.webscripts.DeclarativeWebScript.execute(DeclarativeWebScript.java:167)   at org.springframework.extensions.webscripts.PresentationContainer.executeScript(PresentationContainer.java:69)   at org.springframework.extensions.webscripts.AbstractRuntime.executeScript(AbstractRuntime.java:333)   at org.springframework.extensions.webscripts.AbstractRuntime.executeScript(AbstractRuntime.java:189)   at org.springframework.extensions.webscripts.servlet.WebScriptServlet.service(WebScriptServlet.java:118)   at javax.servlet.http.HttpServlet.service(HttpServlet.java:717)   at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290)   at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206)   at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:233)   at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191)   at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127)   at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102)   at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109)   at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:298)   at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:857)   at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:588)   at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:489)   at java.lang.Thread.run(Thread.java:662)Caused by: java.lang.NoClassDefFoundError: org/activiti/engine/impl/scripting/ExecutionBindings‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Do I have to change the configuration of the H2-DB in the activiti.cfg.xml, or am I missing something else?

Help is very appreciated.
Thaks in advance!

your variable "input" doesn't exist
