Resolving XSLT Import Failures in MuleSoft Runtime Fabric
This technical article addresses a common integration challenge in MuleSoft where XSLT transformations function correctly in the local Anypoint Studio environment but fail upon deployment to Runtime Fabric (RTF). The issue arises when a parent XSLT file attempts to import child XSL files. While local execution successfully resolves file paths using the filesystem, RTF packages resources within an application JAR, requiring classpath-based resolution. The author details failed troubleshooting attempts, including using relative paths, absolute paths, and direct classpath references within the XSLT, which resulted in various I/O and protocol errors. The root cause is identified as the discrepancy between filesystem access in local development and classpath constraints in the containerized runtime. The article outlines the final working solution, which involves modifying how the parent XSLT is referenced to align with classpath usage and ensuring proper dependency configuration. This guide serves as a valuable resource for developers encountering similar deployment issues, providing a clear explanation of the underlying mechanics and a proven fix for ensuring consistent XSLT transformation performance across different MuleSoft environments.
