Need help with invoking Activiti Process

pmsriram13

Hello , this is my first post and I am a newbie at Activiti.

Iam using Activiti 5.10 /Camel 2.10

Here is my Application definition:

I have Camel deployed on tomcat 6.0.18 . I read records in an .csv file, split them and convert to an xml .
After conversion using jaxb, they are sent to an active MQ queue.
No issues so far.

I have Activiti deployed on another tomcat instance(different port) and have used camel to receive the message from the same ActiveMQ and start a process.I have added all the relevant Camel and camel related jars to the activiti-explorer /WEB-INF/lib folder and able to start tomcat and see that camel is also starting(similar to server1)

I followed the example in the Activiti in Action and got the error:

type Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.

exception

javax.servlet.ServletException: org.springframework.beans.factory.NoSuchBeanDefinitionException: No unique bean of type [org.activiti.explorer.ExplorerApp] is defined: expected single bean but found 0:

Note: I have NOT changed the activiti-ui-context.xml and the applicationContext.xml file in activiti-explorer/WEB_INF folder.

If I comment out the

But on un-commenting the above section, i am not able to process the message from the queue due to this error:

Also, if I uncomment out the section : <context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:application-context.xml</param-value>
</context-param>

I cannot open the activiti-explorer page.

Please edit your post and put code tags around relevant parts. That makes it a lot easier to read.

Hope that helps , would appreciate if you could take a look and help me out..

I have no knowledge of camel or spring, so sorry….

jbarrez

Sounds like there is something wrong going on with how the different spring application context files are placed and found. In your web.xml, you look up all files calls *application context … so which files do you have in WEB-INF that would match that?
