Problems starting process-instance via REST

[gant]

Hi,

I¨m trying to start a process-instance via REST.

public void startProcessInstance(String processDefinitionId, Object processVariable) {            JSONObject requestObject = new JSONObject();      requestObject.put("processDefinitionId", "AdhocTaskProcess:1");      requestObject.put("processVariable", processVariable);      // TODO Handling RestClientException      login();      template.postForEntity("http://localhost:15000/activiti-rest/service/process-instance", requestObject, JSONObject.class);         }private void login(){   Credentials credentials = new UsernamePasswordCredentials("kermit", "kermit");   CommonsClientHttpRequestFactory factory = (CommonsClientHttpRequestFactory) template.getRequestFactory();   HttpClient client = factory.getHttpClient();   client.getState().setCredentials(AuthScope.ANY, credentials);}‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

This causes the following exception:

16:17:01,719  ERROR [extensions.webscripts.AbstractRuntime] Exception from executeScript - redirecting to status template error: 01050001 Wrapped Exception (with status template): no deployed process definition found with id 'AdhocTaskProcess:1'org.springframework.extensions.webscripts.WebScriptException: 01050001 Wrapped Exception (with status template): no deployed process definition found with id 'AdhocTaskProcess:1'        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: org.activiti.engine.ActivitiException: no deployed process definition found with id 'AdhocTaskProcess:1'        at org.activiti.engine.impl.db.DbRepositorySession.findDeployedProcessDefinitionById(DbRepositorySession.java:181)        at org.activiti.engine.impl.cmd.StartProcessInstanceCmd.execute(StartProcessInstanceCmd.java:47)        at org.activiti.engine.impl.cmd.StartProcessInstanceCmd.execute(StartProcessInstanceCmd.java:29)        at org.activiti.engine.impl.interceptor.CommandExecutorImpl.execute(CommandExecutorImpl.java:22)        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

Seems, there is no matching process-definition deployed. But, I can see a Version 1 of "AdhocTaskProcess" in Activiti-Probe, and I can start an instance of this via Activiti-Explorer…

Here is the result of an SQL-Query on my Activiti-Database:

(ID_, CATEGORY_, NAME_, KEY_, VERSION_, DEPLOYMENT_ID_, RESOURCE_NAME_, DGRM_RESOURCE_NAME_, HAS_START_FORM_KEY_) VALUES  ('AdhocTaskProcess:1:815', 'http://www.signavio.com/bpmn20', 'AdhocTaskProcess', 'AdhocTaskProcess', 1, '810', 'AdhocTaskProcess.bpmn20.xml', 'AdhocTaskProcess.AdhocTaskProcess.png', 0),‍‍‍‍

Has anybody hints for me?

Hi,

The ID is no longer "AdhocTaskProcess:1" but now is "AdhocTaskProcess:1:815". A unique identifier is added to the ID (on top of the version) to ensure process definition caches aren't stale when running activiti clustered.
