Advanced Tutorial & Interface

Using Processors


This Interface and related tutorial demonstrate the use of Processors in Route configurations. In this particular exercise, an existing Route (from “Training – Creating a Simple Route”) is modified to Base64 encoded files. We’ll build on the concepts from “Creating a Simple Route” to incorporate a single Processor to perform Base64-encoding of messages. If you have not yet walked through that tutorial or are not familiar with the concepts introduced, we recommend you step through it first.

How to Use This Example

Download the INTERFACE file and save it to your local disk.

icon_sample-dataSample Data

Open the eiConsole, click on the File drop-down menu and select Import Working Directory/Route/Format. Highlight the name of the file to import and press the Import Selected button. The imported Interface will appear in your current Working Directory.

Next, follow the tutorial and walk through it step-by-step. You may check your work against the provided Route (Sample Data).

Creating a New Route in the eiConsole

Begin by creating a new Route in the eiConsole. We recommend naming it “Using Processors” to fit with the title of this exercise. Сonfigure a single Source and Target using a Directory /File Listener and Directory / File Transport. These steps are identical to those covered in “Creating a Simple Route”:

Processors can be added after the Listener stage and/or before the Transport stage. Processors are components that perform a variety of operations, ranging from decompression to applying a Regular Expression to message contents. For this exercise, we will be adding one to Base64 to encode the message contents so that files delivered via the configured Directory / File Transport are Base64-encoded versions of those picked up by the Directory / File Listener.

Add the Processor

To add the Processor, select the Listener (second) stage:

Next, select the “Processor Configuration” tab:

How to Add or Remove Processors

You can now add or remove Processors using the respective buttons, as well as re-order them using the “Move Up” and “Move Down” buttons. Processors are executed in the order listed in the table, so changing the order may sometimes be necessary. To add a processor, click “Add Processor”:

This will open a dialog showing all of the available Processors in a drop-down. Select “Base64 (Output)” from the list:

Also, you can find the desired processor with the Module Search.

All the processors are subdivided into categories.

The Filter field allows the users to search through the processors’ names or descriptions if the “Include description text” checkbox is enabled.

Name the Processor

We can now provide a name for our Processor. For this exercise, we’ll use “Base64 Encoder”:

Once finished, click “Add.” You should now see the Processor listed in the table:

Most Processors require some configuration, but this particular one does not. Depending on your eiConsole version, you may have an “Execute Processor” option available, which allows you to specify if the Processor actually runs or not. Leave this option checked.

Testing the Processor

Our Route is now configured. Switch to the Testing Mode and click the Execute Test:

Viewing the Output at Any Stage

You can view the output of any particular stage by selecting it first from one of the main Stages in the main eiConsole table (“Listener”, “Source Transform”, etc.), then selecting the sub-stage, and then clicking the “View Stage Output” button. In our case, we have a “Listener” and the “Processor” under the “Listener” main stage. Of course, the contents of the stage will vary based on what you’ve provided for your input directory, but here is the output of the Listener stage from using a simple XML sample:

Selecting the Processor stage and viewing that output shows the following:

As you can see, the second stage is after the Base64-encoding Processor has completed. If you check the output directory, you should see a corresponding file.

This concludes the tutorial. Move on to the next tutorial, Using Listeners.
