To view the discussion, visit: https://community.jboss.org/message/726692#726692 -------------------------------------------------------------- Hello, I can sucessfully invoke REST api for starting service, however invoking /rs/process/tokens/*<process instance id>*/transition?signal=*<signal name>* does not send signals to process engine. If I run process locally (in eclipse): # kcontext.getKnowledgeRuntime().signalEvent( eventType, data, kcontext.getProcessInstance().getId()); - all signals reach nodes inside the process. Event/Signal nodes are configured as "external". Here are logs for invoking HTTP requests: DEBUG org.apache.http.impl.conn.DefaultClientConnection  - Sending request: POST /gwt-console-server/rs/process/tokens/5/transition?signal=RODataReceivedSignal HTTP/1.1 DEBUG org.apache.http.wire  - >> "POST /gwt-console-server/rs/process/tokens/5/transition?signal=RODataReceivedSignal HTTP/1.1[\r][\n]" DEBUG org.apache.http.wire  - >> "JSESSIONID: XRW3Gp28tTUF2NLekPsm10e6[\r][\n]" DEBUG org.apache.http.wire  - >> "Content-Length: 0[\r][\n]" DEBUG org.apache.http.wire  - >> "Content-Type: application/x-www-form-urlencoded; charset=UTF-8[\r][\n]" DEBUG org.apache.http.wire  - >> "Host: localhost:8080[\r][\n]" DEBUG org.apache.http.wire  - >> "Connection: Keep-Alive[\r][\n]" DEBUG org.apache.http.wire  - >> "User-Agent: Apache-HttpClient/4.1.3 (java 1.5)[\r][\n]" DEBUG org.apache.http.wire  - >> "Cookie: JSESSIONID=XRW3Gp28tTUF2NLekPsm10e6[\r][\n]" DEBUG org.apache.http.wire  - >> "Cookie2: $Version=1[\r][\n]" DEBUG org.apache.http.wire  - >> "[\r][\n]" DEBUG org.apache.http.headers  - >> POST /gwt-console-server/rs/process/tokens/5/transition?signal=RODataReceivedSignal HTTP/1.1 DEBUG org.apache.http.headers  - >> JSESSIONID: XRW3Gp28tTUF2NLekPsm10e6 DEBUG org.apache.http.headers  - >> Content-Length: 0 DEBUG org.apache.http.headers  - >> Content-Type: application/x-www-form-urlencoded; charset=UTF-8 DEBUG org.apache.http.headers  - >> Host: localhost:8080 DEBUG org.apache.http.headers  - >> Connection: Keep-Alive DEBUG org.apache.http.headers  - >> User-Agent: Apache-HttpClient/4.1.3 (java 1.5) DEBUG org.apache.http.headers  - >> Cookie: JSESSIONID=XRW3Gp28tTUF2NLekPsm10e6 DEBUG org.apache.http.headers  - >> Cookie2: $Version=1 DEBUG org.apache.http.wire  - << "HTTP/1.1 200 OK[\r][\n]" DEBUG org.apache.http.wire  - << "Server: Apache-Coyote/1.1[\r][\n]" DEBUG org.apache.http.wire  - << "Content-Type: application/json[\r][\n]" DEBUG org.apache.http.wire  - << "Transfer-Encoding: chunked[\r][\n]" DEBUG org.apache.http.wire  - << "Date: Tue, 27 Mar 2012 18:18:20 GMT[\r][\n]" DEBUG org.apache.http.wire  - << "[\r][\n]" DEBUG org.apache.http.impl.conn.DefaultClientConnection  - Receiving response: HTTP/1.1 200 OK DEBUG org.apache.http.headers  - << HTTP/1.1 200 OK DEBUG org.apache.http.headers  - << Server: Apache-Coyote/1.1 DEBUG org.apache.http.headers  - << Content-Type: application/json DEBUG org.apache.http.headers  - << Transfer-Encoding: chunked DEBUG org.apache.http.headers  - << Date: Tue, 27 Mar 2012 18:18:20 GMT DEBUG org.apache.http.impl.client.DefaultHttpClient  - Connection can be kept alive indefinitely DEBUG org.apache.http.wire  - << "0[\r][\n]" DEBUG org.apache.http.wire  - << "[\r][\n]" if I look /gwt-console-server/rs/process/definition/*<my process id>*/instances, i can see that they are not "signalable": | | {"instances":[{"id":"1","definitionId":"*<process id>*","startDate":"2012-03-27 20:31:13","suspended":false,"rootToken":{"id":"1","name":"","currentNodeName":"","children":[],"availableSignals":[],"canBeSignaled":false}}}]} | But they have 3 signals defined inside process: I've started looking and gwt console code and.... org.jbpm.integration.console.ProcessManagement:65 | | result.add(Transform.processInstance(processInstance)); | makes transformation, which basically omits *canBeSignaled, availableSignals* fields! ProcessManagementTest also lacks any tests: @Test @Ignore           public void testSignalExecution() {                     // TODO implement           } Of course, I am not sure if this is the cause of ignoring signals. By looking at signal code it seems that processes should be signaled, however I could not setup development environment for gwt-console-server to trace exact behaviour (s. Can anyone share experience with signaling processes running on gwt-console-server (Or a way to setup a debuging environment for gwt-console-server on eclipse)? -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/726692#726692] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
