topic Doesn't activiti explorer was include org.activiti.engine.delegate.JavaDelegate? in Alfresco Archive https://connect.hyland.com/t5/alfresco-archive/doesn-t-activiti-explorer-was-include-org-activiti-engine/m-p/209617#M162747 <HTML><HEAD></HEAD><BODY><SPAN>Hi all and sorry in advance if there is already an answer for my question. I saw other related threads, but not the same situation.</SPAN><BR /><BR /><SPAN>I have some java code that I invoke from my custom tasks, I also have my BPM and it all works both from shell/maven or from Eclipse+Activiti&nbsp; (no server or explorer, only from autogenerated Junit Tests executing my BP). My BP runs and invokes all my Java code perfectly.</SPAN><BR /><BR /><SPAN>So I finally deploy activiti explorer in my tomcat, I place my libraries (jars) in Tomcat classpath and I manually deploy my .bpmn file. It seems to load correctly, so I push the start button in my new process and that's when the problem comes. It says:</SPAN><BR /><SPAN>java.lang.ClassNotFoundException: org.activiti.engine.delegate.JavaDelegate</SPAN><BR /><SPAN>so I add to Tomcat classpath one more jar: activiti-engine-5.14.jar</SPAN><BR /><SPAN>Now the problem is different… and crazy:</SPAN><BR /><SPAN>org.activiti.engine.ActivitiIllegalArgumentException: Incompatible type set on field declaration 'roleName' for class com.blah.MyTask. Declared value has type org.activiti.engine.impl.el.FixedValue, while expecting org.activiti.engine.impl.el.FixedValue</SPAN><BR /><SPAN>So it seems by adding the engine jar there is duplication of classes which (if true) confirms my initial impression: I shouldn't add this engine jar because this is something activiti explorer should already have in the first place.</SPAN><BR /><BR /><SPAN>1* Once activiti explorer is successfully running, should I add ONLY my code, or also some activity jars?</SPAN><BR /><BR /><SPAN>2* Did you have this problem? How do you avoid it?</SPAN><BR /><BR /><SPAN>3* Just in case, is there any better alternative instead of extending JavaDelegate?</SPAN><BR /><BR /><SPAN>In case it helps, so far I only have the basic setup, I mean, I just deployed in tomcat the activitiexplorer was as it comes so only in-memory DB and so on.</SPAN><BR /><BR /><SPAN>Thank you very much in advance. cheers</SPAN><BR /><SPAN>antonio</SPAN></BODY></HTML> Thu, 26 Feb 2015 10:03:11 GMT antonio_fornie 2015-02-26T10:03:11Z Doesn't activiti explorer was include org.activiti.engine.delegate.JavaDelegate? https://connect.hyland.com/t5/alfresco-archive/doesn-t-activiti-explorer-was-include-org-activiti-engine/m-p/209617#M162747 Hi all and sorry in advance if there is already an answer for my question.
