jab-rpa

This project is a solution to a problem I had:

1. Automate processes that use a 32-bit Java desktop app
2. Do that, necessarily, from a 64-bit Python runtime

(1) means the existing tooling (like robocorp's excellent rpaframework.RPA.JavaAccessBridge) does not work properly.

(2) means, whatever the solution, it will involve some kind of IPC. My tool of choice for this was gRPC.

This project exposes a fairly ergonomic Python API for developing RPA workflows against Java desktop applications. The server includes multi-JVM support (32-bit and 64-bit, Java 8 through 25) and a selector engine with CSS-like syntax.

Quickstart

1. Install from PyPI with the Java version extra:

   pip install jab-rpa[java8]      # Java 8 (proven in production)
   pip install jab-rpa[java17]     # Java 17
   # etc.
   

2. Use it:

from jab_rpa import JabDriver

with JabDriver("My Java Application.*") as driver:
    button = driver.locator("push_button[name='Clear']")
    button.click()

See the full documentation for details.

Disclaimer

This package runs only on Windows, and supports both 32-bit and 64-bit JVMs. If you exclusively target 64-bit JVMs, rpaframework.RPA.JavaAccessBridge is a more mature option.

Note: Only Java 8 has been proven to work reliably in production. Java 11, 17, 21 and 25 are supported experimentally.

Bug reports, issues, discussions and contributions are always welcome.
