 This web application takes the string "Hello from Java" and links to the EDUCHAN program with the channel `MYCHANNEL` and an input container called `INPUTDATA`. The EDUCHAN program reads the data from the input container and reverses the string. The output string is placed in the output container `OUTPUTDATA`, read in by the servlet and displayed on the web page.
 
+## Pre-reqs
+
+* CICS TS V5.6 or later
+* Java SE 1.7 or later on the z/OS system
+* Java SE 1.7 or later on the workstation

 ## Setup
 
 This application links to the COBOL program EDUCHAN, which can be found in `src/main/cobol`.  
 Download and compile the supplied COBOL program EDUCHAN and deploy into CICS.
 
-This sample is a Maven project, which uses the [CICS Bundle Maven plugin](https://github.com/IBM/cics-bundle-maven) to package the web application in a CICS bundle and deploy this to CICS. This requires the CICS bundle deployment API to be enabled in CICS as a [prerequisite](https://www.ibm.com/support/knowledgecenter/en/SSGMCP_5.6.0/configuring/cmci/config-bundle-api.html). Alternatively, if you aren't using Maven, you could take the source from this project and use one of the other methods of deploying the application to CICS such as creating a CICS bundle project in CICS Explorer and adding the source as a dynamic web project include.
