LegacyJ is a software company founded in 1996 to begin the automated migration and conversion of mainframe COBOL to Java using a high-speed cross-compiler to do the work.

As the Java environment matured with the announcement of J2EE, the need for a CICS replacement product was met with the “LegacyJ Transaction Processor”, a Java-based product to complement the Java code generated from the “PERCobol” compiler. Together, they would allow a mainframe application to be seriously reduced in size and budget while maintaining the original transaction-oriented environment.

The company’s management changed at the end of 2008, effectively restarting the company’s product, marketing, and sales efforts, focusing more on partnerships, specific COBOL/CICS mainframe customers, public sector projects in need of serious assistance, and beginning the task of educating the marketplace on the “Right Way” to successfully modernize old application environments.

LegacyJ’s new strategies are designed to

• rapidly address the budgetary pain of running COBOL mainframes,
• to reduce the serious risks of conversion projects, and
• to provide a broad set of comfortable choices for each of our customers in how they move ahead to modern transaction processing environments.
