AWS Transform - JSP 2.1, Apache Struts 1.0

AWS Transform custom supports a wide range of transformation patterns, including framework upgrades and migrations. While the available information doesn't specifically mention JSP 2.1 or Apache Struts 1.0 as pre-built transformations, AWS Transform custom allows you to create custom transformation definitions for organization-specific needs and proprietary framework migrations.

If out-of-the-box transformations don't support JSP 2.1 and Apache Struts 1.0, you can create your own custom transformations. To do this, you would:

1. Use the AWS Transform CLI to initiate the transformation definition process using natural language to describe what you want to accomplish
2. Provide relevant information about your specific modernization requirements as needed
3. The system will generate a transformation definition as a markup file (SKILL.md) containing a summary and comprehensive implementation steps
4. Optionally include a references folder with additional knowledge items to improve transformation quality
5. Once created and published to the transformation registry, you can execute this custom transformation across your codebase

The advantage of creating custom transformations is that you can codify your specific modernization requirements, create reusable transformation patterns, and apply organizational best practices consistently across multiple projects. AWS Transform custom uses agentic AI and learns from every execution and developer feedback, continuously improving transformation quality without requiring specialized automation expertise.
