- Unable to get tasks for another users by Remote JAVA API;
- Unable to get tasks for another users by Intelligent Process Server API or endpoints;
- The following error messages are thrown when trying to use different users for Task operation and for REST authentication:
org.kie.remote.client.api.exception.RemoteApiException: The user id used when retrieving task information (user1) must match the authenticating user (user2)!
ERROR [org.kie.server.remote.rest.jbpm.UserTaskResource] (default task-55) Unexpected error during processing id to load is required for loading: java.lang.IllegalArgumentException: id to load is required for loading
It is the expected behavior designed for security reasons. By default authenticated users are supposed to see and perform actions only over its own tasks.
Below is described how to change this default behavior:
For Remote JAVA API
The security check can be disabled by setting the system property
org.kie.task.insecure=true for the server where Business Central is running.
E.g for JBoss EAP:
<system-properties> <property name="org.kie.task.insecure" value="true"/>
In the client side the same system property should be also set or the method "disableTaskSecurity()" in the RemoteRuntimeEngineFactory should be used as follows:
RuntimeEngine engine = RemoteRuntimeEngineFactory.newRestBuilder() .addUrl(new URL(APP_URL)).addUserName(USER) .addPassword(PASSWORD) .addDeploymentId(DEPLOYMENT_ID).disableTaskSecurity().build();
For Intelligent Process Server
The system property
org.kie.server.bypass.auth.user=true should be set for the server where
kie-server.war is running.
E.g for JBoss EAP:
<system-properties> <property name="org.kie.server.bypass.auth.user" value="true"/>
If Intelligent Process Server Java Client API (kie-server client) is used for interaction with the server, that property has to be configured on the client site too. Then the user param is added to the rest url (i.e.
kie-server/services/rest/server/queries/tasks/instances/pot-owners?user=redhat_user&page=0&pageSize=200&sort=&sortOrder=true'). However if it is not used, then append
?user=SOME_USERNAME to the related Task REST endpoints.
Listing User Tasks Assigned As Potential Owner
User Task is assigned to a group, you would need to use getTasksAssignedAsPotentialOwner(String userId, List
Most of operations can be done following the steps above like list, initiate and complete tasks. However claiming tasks on behalf of another user will not be possible if you are using the default Human Task callback JAASUserGroupCallback. See our knowledge base article about this Unable to claim tasks on behalf of another user.
