Merged REST and Explorer but getting {'errorMessage':'No router defined','statusCode':500}

[nimsharm]

Hi,

I am new to Activiti and merged the REST and explorer modules based on steps mentioned in the following thread:

http://forums.activiti.org/content/how-merge-activiti-rest-and-explorer-single-war

I put the default h2 DB back in place and removed the LDAP portion. The activiti/WEB-INF/classes/org/activiti/explorer and activiti/WEB-INF/classes/org/activiti/demo folders were missing,I put them in placed too. Now, when I try to make a GET request to http://localhost:8080/activiti/service/process-engine, I am getting {"errorMessage":"No router defined","statusCode":500} in the response. Not sure what could be wrong. Any pointers on what to check would be greatly appreciated!

Update: I did the merge manually and this seems to be working now!

Would you be able to push your project (the one that didn't work) on github so I can take a look at it?

I might create a branch with the demo stuff and H2…

Cheers.

I've uploaded the code here:

https://github.com/n-tiwari/Activiti-merge-raimana

Let me know if you can/cannot access this 🙂
If you would like, I can upload my code there as well. I just did a very basic merge for the two components with demo and I've tested that.
