Call jar from alfresco workflow

biker89 — Thu, 25 May 2017 13:07:21 GMT

I have a jar file with this structure:ActivitiProj-src --com.mycompany.activiti ---Decision.java-META-INF --Manifest.mf-lib --activiti-engine-5.22.0.jar-alfresco --extension ---custom-action-context.xmlDecision.javapackage com.mycompany.activiti;import org.activi

Are you serious about the JAR having the structure you outlined? A JAR addon to Alfresco should never contain other JARs in a lib/ sub folder, and any Java code needs to be included as compiled *.class files in a JAR (unless it is a JavaDoc or source JAR). How are you creating the JAR? It is highly recommended to use the Alfresco SDK if you are new to Alfresco development. You may also want to check out Jeff Potts' tutorial about advanced workflows in Alfresco.

Axel, I am sorry, can you please explain what do you mean? why I can't add one jar to another?
I can call my jar with the same structure from alfresco workflow, I just need to add .xml file here:
alfresco-community\tomcat\shared\classes\alfresco\extension

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC '-//SPRING//DTD BEAN//EN' 'http://www.springframework.org/dtd/spring-beans.dtd'>
<beans>
 
    <bean id="decision" class="validationdecision.ValidationDecision">
    </bean>
 
</beans>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

and put my jar here
alfresco-community\tomcat\webapps\alfresco\WEB-INF\lib

and add to my workflow

So my class ValidationDecision looks like: (just for testing)

public class ValidationDecision implements JavaDelegate
{
     @Override
     public void execute(DelegateExecution execution) throws Exception
     {
                System.out.println (execution.getVariable("docId").toString());
     }
}‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

And I can see valid docId output in log here alfresco-community\tomcat\logs\alfrescotomcat-1-stdout (when I start my workflow ofcourse).

So jar is called successfully.

What I pointed out was that the JAR structure you outlined in your original question would not work.

a) It contains source code, not a compiiled class, and

b) it contains the activiti-engine JAR, which is both unnecessary (Alfresco already incldues Activiti) and without effect (JARs inside JARs should not be loaded by the default class loaders)

What you may have failed to mention is that this may not have been the final JAR structure but your source project structure, with the final JAR file looking completely different.

Apparently the JAR in your own reply contains a different class and maybe a different structure to the original issue.

Oh, of course u r right, this is just a project structure, it's my fault)
