Web Service Task

Overview

The Web Service Task allows you to invoke a Web Service running on any application server.

SSL/TLS Secured HTTPS

Web Service Tasks support the use of https:// instead of the non-encrypted http:// for the Web Service Task URL.

This requires setting up a truststore (keystore) and setting the following properties in the Universal Controller Start-up Properties (uc.properties) file:

You must make sure that the HTTPS server's certificate (or root certificate) exists in the truststore that is referenced by these two properties. This is required to validate the remote web service providers identity. Universal Controller does not provide an option to bypass https certificate validation.

The hostname in your URL is verified against the certificate and must match the certificate's CN (Common Name) or SAN (Subject Alternative Name).

Preemptive Authentication

The default behavior of Apache HttpClient library used by the Web Service task is to not use pre-emptive authentication out of the box, because if misused or used incorrectly, the preemptive authentication can lead to significant security issues, such as sending user credentials in clear text to an unauthorized third party.

Therefore, users are expected to evaluate potential benefits of preemptive authentication versus security risks in the context of their specific application environment.  Thus, Web Service Tasks using Basic Authentication will not pre-emptively send authentication credentials until prompted by the receiving API. Please see the following link for more information.

For a task within a workflow, the duration is the period between the time the workflow starts and the time the task itself starts. For example, a task might have a Late Start Duration of 60 minutes. If the workflow starts at 9:00 a.m. but the task itself does not start until 10:30, the task has started late.

For a task that is not within a workflow, Late Start Duration has meaning only if the task has been held upon starting. For example, if a task has a Late Start Duration of 60 minutes and the Hold on Start field is enabled, if the task is not released from hold within the amount of time specified in the Late Start Duration field, the task has started late.

Late Finish

If enabled, and if the task instance finishes after the time or period specified, the task instance is flagged as late. You can specify a time or duration to determine a late finish (see Late Finish Type). To determine whether a task instance finished late, open the task instance and locate the Finished Late field; the field is checked if the instance finished after the specified time or lasted longer than expected.

Critical Path Options

This section contains Critical Path-related specifications for the task.

CP Duration

Optional; Allows you to override the estimated Critical Path Duration of the task when running in a Workflow; used in conjunction with the CP Duration Unit field. In most cases, this field should be left blank, which implies that the Controller will estimate the Critical Path Duration based on historical executions. Valid values are any integer equal to or greater than 0. Variables and Functions are supported.

CP Duration (Resolved)

Displays the current resolved value of the CP Duration field, which may contain variables or functions that will be displayed as unresolved until the task instance starts. The CP Duration (Resolved) field can continue to change value until the task instance starts, at which time CP Duration will display as resolved and CP Duration (Resolved) will no longer be visible unless there was an issue resolving the variables and/or functions contained within CP Duration. If the Controller is unable to resolve CP Duration or it resolves to an invalid value, CP Duration will be ignored and the Controller will estimate the Critical Path Duration based on historical executions.

CP Duration Unit

Type of CP Duration; used in conjunction with the CP Duration field. For example, for a CP Duration of two minutes, specify 2 in the CP Duration field and select Minutes in this field.
 

Options:

Specification for whether or not there is a restriction for this task to be run, skipped, or held.

Options are:

  • -- None -- No restriction for this task.
  • Run Restriction for when this task will be run.
  • Skip Restriction for when this task will be skipped.
  • Hold Restriction for when this task will be held.

If Execution Restriction on a task is Run or Skip, then when it is part of a Workflow that is being launched, the Restriction Period is evaluated. The task instance will be skipped if Execution Restriction is Skip and the date is within the Restriction Period or Execution Restriction is Run and the date is not within the Restriction Period. Execution Restriction can be set to Skip with a Restriction Period of - None -, meaning the restriction is always active and the task will be skipped when it is part of a Workflow.
