PI 7.30 HTTP Java Adapter Test Tools
At PI 7.11 and before, the HTTP adapter is an ABAP adapter. PI 7.3 introduces a new HTTP adapter (HTTP_AAE) based on the java stack, using the java Adapter Framework.
In this blog, we will take a look at a couple of test tools that we can use to test the HTTP_AAE adapter.
Introduction
In PI 7.3, in addition to the exiting HTTP adapter in ABAP, a java adapter (HTTP_AAE) has also been added. This new java adapter uses a java service to send the payload to the AAE of PI 7.3. The java adapter also provides two different methods of sending the payload, GET and POST, therefore, the need for 2 different test tools.
One of the benefits of using the HTTP_AAE adapter is to bypass the ABAP stack during message processing, which can increase the performance by as much as 10X. In addition, this adapter is a must-use when we install a java-only PI system without ABAP.
HTTP_AAE Adapter Overview
The URL to send the payload will be generated by the test tool with the following information. This is also the URL used for POST.
sender-business-component-name
Business Component name or Business System name used in the Integrated Configuration
quality-of-service
must be either BE or EO
With GET, the following URL is generated by the test tool. It is identical to the *POST* URL, except for the last parameter:
Main-Payload-Parameter-Name
the Main Payload Parameter Name used in the HTTP_AAE communication channel configuration
the pay load
must be URL encoded so that special characters, e.g. "<" and ">" can be sent without problem.
- POST

HTML code which can be copy-n-pasted to a file with a file extension of .html, e.g. http_aae_Test_730_post.html.
