Convert COBOL to Java

Automated Application Conversion

Do you need to convert your COBOL application to Java? In this case, Ispirer products will be the perfect solution for your project!
Human-written code in each project has its own specifics. It may seem difficult to obtain a high level of automated conversion. With Ispirer it will be a smooth transition. The main advantage of Ispirer Toolkit is the personalization for your conversion project. As a result, you will replace the old technology with all its downsides. The outcome will be a new application without any middleware used afterwards.

How it Works

Ispirer Toolkit

Automated conversion of COBOL to Java with the help of our tool makes it possible to significantly reduce the time and expenses as compared to manual rewriting of the application. The following approach allows to ensure high quality of automated conversion:

1. Preliminary Stage

The stage is carried out to determine the current conversion level of Ispirer Toolkit. The level of conversion depends on the complexity of the source code and the requirements for the target application. You can independently perform the analysis of the source code of your COBOL application, as well as try to convert it to Java using the demo license. Besides, our experts can perform the source code analysis and provide you with examples of its conversion.
If your application is quite specific and large, we recommend to perform PoC to determine the maximum level of automated conversion of your project.
As a result, we will find out whether the customization is required or you can directly proceed to the conversion.

2. Ispirer Toolkit Customization Stage

If this stage is necessary, we will perform the customization to thoroughly prepare the toolkit for the conversion according to your project requirements. We will take a part of a representative code that amounts ussually to ~100,000 lines. The Ispirer technical team will add all the required conversion rules into the tool to achieve the highest possible level of automation or even to get a compilable result. As a delivery, we will provide conversion results of the scope of this customization. The customer will get a tailored and updated tool according to his specific project needs.

3. Use of Ispirer Toolkit

At this stage, you perform the conversion yourself. As to pricing, we apply project-based licensing. Prices depend on its scope and duration. The license includes support as well. If necessary, the conversion may be further improved even at this stage. As a result, customization requests, each of which is processed within 1-3 business days, are added to the license. Our experts will recommend the optimal number of requests considering the complexity and requirements of your project.

Ispirer Migration and Modernization Service (Ispirer Service)

Our experienced team can provide you with a turnkey migration service and convert your entire COBOL application to Java, delivering you a ready-to-use application in due time. Our responsibilities include not only professional analysis, assessment, performance and testing of your migration, but also services such as adding new or changing existing functionality of the application.

If you want to get an intermediate result of the converted COBOL code in the Java language, the Ispirer team will be glad to provide you with a basic migration service. As a result, you will get code that is optimized to the compilable level. Further, you will have to independently bring the application to a fully functional state in accordance with your requirements.

You are free to choose a preferred option. Nevertheless, we can provide an estimate of both the Tool and the Service, and give professional advice.

Conversion Overview

Ispirer Toolkit automatically converts COBOL to Java, considering the specifics of these languages. As the result of the conversion, Java class is generated for each source file (.cbl, .cob, .cpy). The class name is formed from the PROGRAM-ID specified in the Identification division, taking into account the camelCase rule of the Java language. Variables from the Data division are migrated to class variables, and paragraphs from the Procedure division are migrated to class methods. When using structures in COBOL, additional classes are formed for them in Java.
Besides, our tool processes COPY and INCLUDE clauses, creating a class object derived from the conversion of the header file. At the same time, dependencies and data types used in the header files are automatically taken into account.
In order to achieve a high level of automation and get maintainable code, we have developed a special Java framework, which is used by the conversion results.

Variable Conversion
Ispirer Toolkit automatically converts all COBOL data types, taking into account PICTURE (PIC) and USAGE clauses. For exact data type matching, we use generic Java classes.

Code Conversion
Each paragraph is converted to the class method. At the same time, the call and completion of each method automatically consider the possibility of using PERFORM and GO TO statements. COBOL statements and functions, which do not have analogues in Java, are converted to the class methods of our framework.

Working with Database
Database access in the COBOL application can be converted to JDBC or Hibernate. In addition, if the Java application needs to work with another database, you can convert the embedded SQL, as well as the database itself. You can learn more about database migration using Ispirer Toolkit in a special section of our site.

Working with Files
Ispirer Toolkit supports conversion of files of all three types: sequential, indexed and relative. As a result, file algorithms are automatically moved from COBOL to Java without changes.
