Avoid generating demodata in rest-webapp

[b_schnarr]

Hello at all,

I have the following deployment:

One MySQL-Database for both instances (activiti-rest.war and activiti-explorer.war). Database name is activiti.
First, I deployed the activiti-rest.war. After that, I configured the database like this in db.properties:

db=mysql
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/activiti?autoReconnect=true
jdbc.username=activiti
jdbc.password=activiti
‍‍‍‍‍‍‍

After that, I copied the mysql-connector-java-5.1.27-bin.jar in the corresponding lib-Folder. In addition, I disabled the generation of demodata for the rest webapp in the activiti-context:

   <bean id="demoDataGenerator" class="org.activiti.rest.service.demo.DemoDataGenerator"
      init-method="init">
      <property name="processEngine" ref="processEngine" />
      <property name="createDemoUsersAndGroups" value="false" />
        <property name="createDemoProcessDefinitions" value="false" />
        <property name="createDemoModels" value="false" />
   </bean>
‍‍‍‍‍‍‍‍‍

After that, I deployed the activiti-explorer.war, pointing to the same db. I changed db.properties to the same code as above. After that, I copied the MySQl-Connector in the lib-Folder. I did NOT change the generation of demodata. Therefore, the explorer will generate demodata.

After the deployment, everything works fine, I have no tasks. The explorer is empty except of the demodata.
After I did one REST-Call for testing, e.g.  get-Request to : http://ip-address:8080/activiti-rest/service/identity/users, the activiti explorer is full of tasks in inbox, Queue, Involved etc (see picture: https://www.dropbox.com/s/r7e4mfd4oqakfn1/explorer.png). In the middle of explorer, there is the message: Warning: userid is null. All tasks are discribed with lorem ipsun text.

Why does this happen? I explicitely disabled the generation of demodata in the rest webapp. But after the first rest-call, the explorer looks like the picture. Any ideas?

Thank you very much for your help

One step further: When I just deploy the activiti-rest.war (without the activiti explorer), the webapp generates after each restart an entry in the two tables act_hi_taskinst and act_ru_task even though I disabled the generation of demodata. The table act_ru_task looks like this after some restarts: https://www.dropbox.com/s/3a4u16nzlupus3a/activiti-database.png

Does anyone has a solution?
Thank you very much

The issue with the REST web application generating demo tasks is fixed in Github master. So it will be fixed in release 5.15.

Found a workaround: When you set the properties in the activiti-context.xml to false like this:

<code>
<bean id="demoDataGenerator" class="org.activiti.rest.service.demo.DemoDataGenerator"
  init-method="init">
  <property name="processEngine" ref="processEngine" />
  <property name="createDemoUsersAndGroups" value="false" />
        <property name="createDemoProcessDefinitions" value="false" />
        <property name="createDemoModels" value="false" />
</code>
the rest app still produces demo data. If you comment out the whole code-block like this:

<code>
<!– Comment this if you don't need demo data
<bean id="demoDataGenerator" class="org.activiti.rest.service.demo.DemoDataGenerator"
  init-method="init">
  <property name="processEngine" ref="processEngine" />
  <property name="createDemoUsersAndGroups" value="true" />
        <property name="createDemoProcessDefinitions" value="true" />
        <property name="createDemoModels" value="true" />
</bean>
  –>
</code>
no demo data will be generated.

I've found a solution for this problem but I don't know, how much is this stable!!

After configuration Activiti-Rest and Activiti-Explorer to use the same PostgreSql database, I ran into this problem!

I've tried to modify the Postgres tables and clean the demo data to solve the problem. I use ECM postgreSQL manager to remove demo data from tables. But the DELETE status of act_ru_identifylink (and also other tables that have the demo data and you should clean them) should be changed to CASCADE.

After cleaning database, I can run my REST properly. Also I don't have any strange Latin task in Kermit task list. For the second time that I wanted to run my Tomcat, I've commented out the whole code-block in activiti-context.xml.

It works now properly! I don't know, how much is this solution reliable!
