How to use 0.1.0-alpha1?
ThorbenLindhauer opened this issue · 6 comments
Hi guys,
I just wanted to try out the 0.1.0-alpha1 war, but am not sure how get it working. I tried deploying it on Tomcat and Wildfly 10 (both the Camunda 7.7.0 distributions) and failed both times.
On Tomcat, the deployment is successful, but accessing http://localhost:8080/camunda-bpm-graphql-0.1.0-alpha1/?query={tasks{name}} returns 404.
Deploying to Wildfly 10 fails with the following exception:

So my question is: Could you please clarify how to deploy and access the web application?

Hi Thorben,
thanks for feedback.
Hmm, at least for the Tomcat-deployment I do not see any problem.
For Wildfly I must admit I didn't have time to test it yet. Maybe @zerounix can help us here?
So, here are the steps I did for Tomcat:
- Downloaded Alpha1 Release from https://github.com/camunda/camunda-bpm-graphql/releases/tag/0.1.0-alpha1
- unzipped content to new project folder
- set auth=NO in application.properties (although not necessary for my deployment target)
mvn clean package
- copied the created war-file to the remote webapps folder
/opt/camunda-bpm-tomcat-7.7.0/server/apache-tomcat-8.0.24/webapps
on loydl-staging.ch
This server is a plain vanilla Camunda-BPM-Tomcat-7.7 server. - deployment successful: a new folder
/opt/camunda-bpm-tomcat-7.7.0/server/apache-tomcat-8.0.24/webapps/camunda-bpm-graphql-0.1.0-alpha1
was created - opened this URL and got the expected result
(after the browser asked for user/password --> use demo/demo):
http://loydl-staging.ch:8080/camunda-bpm-graphql-0.1.0-alpha1/?query=%7Btasks%7Bname%7D%7D
With GraphiQL you'll see this for example (querying the process instances on that server):
When using GraphiQL on this server you have to setup Basic Authentication - so use this Authorization-Header in GraphiQL:
Authorization
Basic ZGVtbzpkZW1v
Let me know if that works for you.

Hi Harald,
Since we have a release now, I tried to deploy the released artifact (accessible here: https://app.camunda.com/nexus/content/groups/public/org/camunda/bpm/extension/graphql/camunda-bpm-graphql/0.1.0-alpha1/camunda-bpm-graphql-0.1.0-alpha1.war), so I wouldn't have to build it from the sources. Could you please check if this runs on your Tomcat installation? If not, then I'll go with the build-from-source option :)
Cheers,
Thorben
Hi Thorben,
just cloned the current repo
-
build with mvn clean package -Pwildfly
-
copied the war file to a fresh camunda 7.7.0 wildfly
works as expected.
Maybe one thing is different in my case (or the jboss case) the URI is http://localhost:8080/graphql/schema.json and contains no -SNAPSHOT or -alpha.
Your actual ClassCastException seems strange to me, as i just changed the maven build a little, nothing wild or fancy. What kind of wildfly did you use?
If you could give me more insight, i might be able to help.
Hi Thorben,
I checked with the released artifact from https://app.camunda.com/nexus/content/groups/public/org/camunda/bpm/extension/graphql/camunda-bpm-graphql/0.1.0-alpha1/camunda-bpm-graphql-0.1.0-alpha1.war
Yes, it runs on the Tomcat installation as expected.
Thanks guys. I'll try harder then :)
@zerounix I guess the alpha1 artifact wasn't built with the wildfly
profile resulting in the exception.
FYI: The solution was using Java 8, in particular setting the JRE_HOME
variable to a Java 8 jre :)
