Convert PowerBuilder to Java

Delivering you an intelligent and high quality result in due time!

Automated Application Conversion

Do you need to convert your PowerBuilder 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 PowerBuilder 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 PowerBuilder 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 Samples of PowerBuilder to React and Java

PowerBuilder programs consist of Workspaces (starting from PB 8.0 and higher, these are .pbw files). Conceptually, they are similar to Solution. These are text files consisting of paths to the Target files (.pbt files) that correspond to the concept of Project. The Target files are in text format, and each contains paths to the PowerBuilder libraries (.pbl files that store source code files in binary format). Typically a library with the same name as the Target file has a .sra entry point file.

To convert a PowerBuilder application, you need to extract all source files from the appropriate Workspace libraries (or Target, if PB version is less than 8). You can download Ispirer PowerBuilder Metrics to get a statistical report on PB sources, as well as extract source files from PowerBuilder libraries using Workspace, or a set of Target files, or a set of particular PB libraries (.pbl files) that need to be converted.

Once the source code is extracted, for each PowerBuilder library file, a corresponding folder named library will be created with all the source code extracted. The folders will contain source files with the following file extensions:

  • .SRD - DataWindow source files
  • .SRW - Window source files
  • .SRM - Menu source files
  • .SRU - Custom user object source files
  • .SRS - Structure source files
  • .SRP - Data pipeline source files
  • .SRF - Function source files
  • .SRQ - Query source files
  • .SRA - Application source files

Now you can use Ispirer nGLFly Wizard to convert it to your chosen target technology.
Basic source type conversion by extension:

  • .SRD - converted to 2 files. One file is named DatawindowObjectName.ts (located on the client) - the UI and code for the DataWindow object. The other file is called (located on the server) that contains the sql query.
  • .SRW - converted to 2 or 3 files. The files are named WindowObjectNamePage.tsx and store.ts (located on the client) - the UI and code of the Window object. If the source file contains sql queries, the file is converted to the server with sql queries.
  • .SRM - converted to 1 file named Menu ObjectName.tsx. – the UI and menu object code.
  • .SRU - converted to 1 file named store.ts for the non-visual object and 2 files named store.ts and UserObjectName.tsx - the UI and code of the User object.
  • .SRS - converted to 1 file named StructureObjectName.ts. The file contains a class with variable declarations from the PowerBuilder structure.
  • .SRP - not used for conversion.
  • .SRF - converted to 1 file named functionObjectName.ts. The file has a public function.
  • .SRQ - not used for conversion.
  • .SRA - converted to 1 file named applicationObjectName.ts. The contents of this file are used to copy into the project's entry point file in the same way as in the conversion sample.

After the conversion, you need to create a WPF application desktop project in Visual Studio and add the converted files from the results folder to it. There is the Ispirer framework for converting PowerBuilder to React and Java (IspirerFramework) in the results folder.
Note: this is a special framework provided by Ispirer. It extends the target technology to enable specific source code features.

What Our Customers Say

"Beckman Coulter provided as much of the information as we could but there was a lot of functionality that we did not know. This is where Ispirer talents became apparent as they forensically reengineered functionality."

"We are now successfully running live on the new system, with the updated PB apps. I want to express my thanks to Ispirer team. You made this project a success!!! I was happy to work with you and would highly recommend Ispirer!"

"Because of Ispirer and MnMTK, our team was able to devote its time to build the infrastructure for new Java programs instead of spending time on converting code. The produced Java code met all our maintainability, readability and performance requirements."

"This approach was very successful avoiding any confusion at the first stage, and achieved high conversion rate in the end. The project was completed successfully, they say they couldn't make it without MnMTK 2017 and excellent extension support from lspirer."

"At the onset of the engagement the Ispirer MnMTK was expanded to meet the specific requirements of our migration prior to being delivered for our use. Once this phase of the project was complete we were provided with the expanded toolkit."

"We have found the Ispirer team to be knowledgeable and responsive and we have found the tooling to be flexible enough to be easily adapted to our coding conventions."
