Deploying a Java Service Interface and Using Resource Adapters

Calling Procedural COBOL from Java
This chapter describes how you can access legacy procedural COBOL programs from Java using the support provided in the com.microfocus.cobol.RuntimeSystem class.

Calling Java from OO COBOL
This chapter shows you how to code a COBOL program to call Java methods using the OO COBOL Java domain.

Calling OO COBOL from Java
This chapter describes how you can access COBOL objects from Java programs. This is slightly different from the method for accessing procedural COBOL from Java programs.

Java Data Types
This chapter describes how COBOL and Java data types are mapped on to each other.
