Download java files
Is there a way to retrieve all the backend java(jar) files for a certain (entire) application that we built in Pega?

@Sairohith Thanks for the response. The jar being extracted from the product rule(RAP) would only have the binary(.bin) files. we are looking for the jar of java files of an application. Is there a way?

@Saravanan M Pega does not provide a direct way to extract JAR files with the full Java source code of an application, as it dynamically generates and compiles Java at runtime. However, you can view Java code by navigating to specific rules like Activities or Data Transforms and selecting Actions > View Java to see the generated code. For custom Java, go to Records > Technical > Library or Function and download individual components. If you have server access, check the PRGenClasses or WEB-INF/classes directories for compiled .class files, which can be decompiled into .java using tools like JD-GUI. Additionally, enabling "Generated Java" logging from Configure > System > Operations can help you trace runtime Java generation. While the Product Rule (RAP) includes compiled binaries, these methods allow partial access to the underlying Java code of your application.
@Saravanan M To retrieve all the backend Java (JAR) files for an entire Pega application, you can create a Product Rule in Pega Dev Studio. Go to Configure > Application > Distribution > Package > Create Product File, and include the entire application along with rulesets, library rules, and function rules to ensure all Java-based components are captured. Export the Product Rule as a ZIP file, which will contain the required JAR files. If you need specific Java code, navigate to Records > Technical > Library and download any listed JARs or custom code. For direct server access, you can locate the JAR files in the Pega installation directory under /lib or /WEB-INF/lib. This method covers both custom Java functions and external libraries used in your application
