Hi,
I am able to call Rest call when activiti-rest web application is pointing to H2 database.I want to change H2 database to oracle.
I executed scripts given in Activiti in the oracle and modified db.properties file in Activiti-explorer and Activiti-rest web applications.
Activiti-explorer working fine i could not call Activiti Rest calls. Below error i am getting.

{"errorMessage":"couldn't initialize process engine from spring configuration resource file:/D:/apache-tomcat-7.0.42/webapps/activiti-rest/WEB-INF/classes/activiti-context.xml: null","statusCode":500}

Please suggest me on this.
regards,
suresh

Hi Suresh,

It is hard to guess from such a short error description
Did you configure your DB according to doc?

Did you drop the rest war in Tomcat too?

Did you try GET http://127.0.0.1:8080/activiti-rest/service/repository/deployments Should give you something if it's installed correctly

Re: Activiti Rest API tutorial

osamamahmoud — Wed, 08 Apr 2015 13:43:32 GMT

Yes I added it and the URL above gives me
HTTP Status 404 - /activiti-rest/service/repository/deployments

type Status report

message /activiti-rest/service/repository/deployments

description The requested resource is not available.

Apache Tomcat/7.0.53

Re: Activiti Rest API tutorial

jbarrez — Tue, 14 Apr 2015 11:54:46 GMT

Okay, and you see the war is exploded? You've checked all log files?
Like I said, if that's all correctly configured, it should be available on that url.

Re: Activiti Rest API tutorial

osamamahmoud — Thu, 16 Apr 2015 11:57:59 GMT

Yes the file exploded and don't know how to trace this issue can you please Gide me

Re: Activiti Rest API tutorial

yvoswillens — Thu, 16 Apr 2015 13:14:15 GMT

Try setting the Tomcat loggin to a more verbose level and check your logs.
Did you check that the REST app is deployed with the correct context? (f.e. with the Tomcat manager app)

I was also getting 404 "The requested resource is not available." when calling http://localhost:8080/activiti-rest/service/repository/deployments

Changed to http://127.0.0.1:8080/activiti-rest/service/repository/deployments and now it works.

Please post the steps you've done. It should be nothing more than changing db.properties.
