Can we execute a jar file in snaplogic
Executing a JAR File in SnapLogic Yes, you can execute or leverage JAR files in SnapLogic, though there is no dedicated "Run JAR" snap. Here are the supported approaches: --- β Option 1: Use the Script Snap (Recommended) The Script Snap allows you to write scripts in JavaScript, Python (Jython), or Ruby (JRuby) using the JVM ScriptEngine mechanism. You can: - Import and use Java classes from a JAR file directly within your script. - Place your custom JAR file in the appropriate directory on your Groundplex node (e.g., /opt/snaplogic/ext_jar/). - Reference the JAR in the Jython configuration file (.jython) using the python.path property:
python.path=/opt/snaplogic/ext_jar/your-custom-library.jar
- Then import and invoke the JAR's classes within your script.
β οΈ Note: Importing third-party/custom JAR libraries is only supported on Groundplex nodes, not on Cloudplex.
--- β Option 2: Use a Custom Snap If you want to deeply integrate JAR functionality into SnapLogic as a reusable component, you can develop a Custom Snap that wraps your JAR logic. This requires Java development using the SnapLogic Snap SDK. --- β Option 3: Execute an External Process via Script Snap (Groundplex Only) On a Groundplex, you can use the Script Snap to invoke an external process (e.g., java -jar yourfile.jar) using system-level calls. This is not supported on Cloudplex. --- π Key Considerations | Factor | Detail | |---|---| | Cloudplex | External process creation is not allowed | | Groundplex | External processes and custom JARs are supported | | JAR placement | Place JARs in /opt/snaplogic/ext_jar/ on each Groundplex node | | Multiple nodes | You must add the JAR to each node in your Groundplex | --- Summary The most practical approach is to use the Script Snap on a Groundplex, place your JAR in the ext_jar directory, and invoke its classes via a Python, JavaScript, or Ruby script. Would you like help building a pipeline that uses the Script Snap to invoke your JAR file?
