LegStar, an open source mainframe integration solution

LegStar is set of development tools and execution runtimes aimed at integrating legacy COBOL applications with Java and SOA technologies.

Common use cases:

Service-enable a COBOL/CICS program LegStar generates COBOL/CICS adapters for JAX-WS, JBoss ESB or Mule ESB.

LegStar provides COBOL transformation capabilities and CICS execution runtime (Commarea or Containers), over Sockets, HTTP or WebSphere MQ.
Transform COBOL payloads LegStar generates Transformers by parsing COBOL fragments, Java classes or XML Schema.

At runtime, z/OS data (containing EBCDIC, COMP, etc.) is transformed to Java and/or XML.

The LegStar Transformers are pure Java and can be used directly in your code.
Access java services from COBOL/CICS programs LegStar generates Java proxies for JAX-WS, JBoss ESB or Mule ESB services.

You get a Java execution runtime that allows your COBOL code to invoke remote services over HTTP.
