a task calls a REST web service and makes the result available to other tasks

forschungsstude — Mon, 07 Mar 2016 11:13:41 GMT

hello,I use Activiti 5.17, Apache Maven 3.3.3, Apache Tomcat 7.0.62 and jdk 1.8.0_45-b15.My goal is to create a task which calls my own REST-Webservice to receive a simple PIN (4 digits). The next task should wait until the PIN is received. This is the link to my REST-Webservice returning the PIN: h

Hi,
1. you could use a ServiceTask with a delegate class and inside this class you do the web service call and then put the result on the flow as a variable.

2. related to the mule class not found you have to be sure you have the activti-mule.jar in the classpath.

I have also solved this problem by using a script task combined with unirest for java.
This is for activiti 6:
<code>
/*
* Javascript
* http://unirest.io/
* Hint: Use maven to download all the required jar files. Place them in the webapps/activiti-app/WEB-INF/lib.
* mvn dependency:resolve
*/

var objectvar = {};
objectvar.name='my name';
objectvar.subobj = {};
objectvar.subobj.testprop = 'test';

var Unirest = Java.type('com.mashape.unirest.http.Unirest');

var response = Unirest.post("http://httpbin.org/post").body(JSON.stringify(objectvar)).asJson();
var body = response.getBody().toString();
execution.setVariable('fullJSON', body);
var bodyObj = JSON.parse(body);
execution.setVariable('MyIp',bodyObj.origin);

/* Another example

var response = Unirest.post("http://httpbin.org/post")
.header("accept", "application/json")
.queryString("apiKey", "123")
.field("parameter", "value")
.field("foo", "bar")
.asJson();

*/

hello,
thanks for your help.

"This is for activiti 6" stand for "activiti-6.0.0.Beta2.zip" or?

Yes I am using Beta 2, but it may also work in older activiti 5.
The script will probably not work as is on Java older that java 8, because the scripting engine is Nashorn and not Rhino.

hello,

thanx.
Now I use Activiti 6.0.0.Beta2 and apache-tomcat-8.0.32.

I try –> http://localhost:8080/activiti-app (login: admin@app.activiti.com / test) –> "Identity Management" but there is no "Tenants".
So I cannot define the endpoints as explained in the video "https://www.youtube.com/watch?v=x7YCHYCIxpM".

Any ideas why "Tenants" is missing?

Thank your for your help.

Regards,
Sabine

You are mixing up the Activiti open source UI and the commercial offering by Alfresco. The video is the latter and is different from the one in OSS.

Hello,

thanx for the information.
I hope creating a REST Webservice can also easy create at Acitivit 5.19.0.2.
