Convert Oracle PL/SQL to Java

Automated Application Conversion

Do you need to convert your Oracle PL/SQL 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 Oracle PL/SQL 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 Oracle PL/SQL 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.

Conversion Overview

Ispirer MnMTK automatically converts Oracle PL/SQL to Java, considering the specifics of these languages. Both conversion with connection to the source database, as well as conversion of files containing PL/SQL scripts are possible. Our tool supports conversion of the following objects: packages (specification and body), collection and object types, functions, procedures. At the same time, tables, views, triggers and sequences remain on the side of Oracle. As a result of conversion, each separate database object is converted to a Java class. Class names are formed based on object names, taking into account the Java Naming Convention.
In case, you need your Java application to work with a different database, Ispirer MnMTK can convert Embedded SQL and the database itself.

Variable Conversion
Ispirer MnMTK automatically converts function and procedure variables (nested or not) to method variables, as well as package variables to class variables. The tool supports conversion of all Oracle data types. Moreover, when converting variables, their visibility is taken into account.

Code Conversion
Procedures and functions are converted to classes with one method. Packages are converted to classes, their nested functions and procedures into methods of this class, taking into account their visibility. Initialization block is converted to the class constructor. Oracle built-in functions and procedures are converted either to the same Java methods, if any, or to the methods of our Plsqlutils helper class.

Working with Database
Oracle SQL Statements can be converted to JDBC, Hibernate, Spring JDBCTemplate. In addition, we have implemented the ability to export SQL statements to XML files for their support optimization. Besides, the logic of working with cursors is transferred to Java.

Working with Collections
Ispirer MnMTK supports collection conversion of all three types: Associative array, Nested table, Variable-size array (varray). For optimal collection conversion, we have developed helper classes that allow to repeat the logic of Oracle collections in Java.

Oracle Supplied PL/SQL Package Conversion
Ispirer MnMTK supports conversion of some Supplied PL/SQL Packages, such as UTL_FILE, DBMS_LOB and others. The list can be expanded based on the requirements of your conversion project.
