Struts Action 2 .0 migration tools will assist the Action 1.x application in the migration process. These tools serve two purposes, named #2 and #3 in the MigrationStrategy document.This page discusses what these two collections of tools might look likeinclude the notions of

• bridge objects to utilize existing s1 resources, and
• utilities to convert resources to s2 equivalents.

Dual Processor, Shared Resources

• An Action 2.0 !A s2 TextProvider that retrieves messages from the Action 1.x !s1 MessageResources instance in the servlet contextA Validation interceptor that looks up the action in commons-validation objects loaded by an existing Action 1.x application. The action errors would be translated and stored into a !ValidationAware instance
• An Interceptor that can apply SAF1 validations to s2 actions, converting error messages to s2 format.
• An Action and/or Interceptor that executes a Commons Chain chain

• instance.

Struts 1 Emulation

• Implement s2 Action interface on s1 Action; Extend Session-Aware Interceptor to set properties corresponding to s1 execute parameters and populate ActionForm; Action execute() invokes execute(...) using properties; return ActionForward name.
• Extend aforementioned s1 Action Interceptor to load and process PlugIns

Conversion Wizards

• Utilize XSLT and other text processing tools to convert struts-config.xml to struts.xml, validations.xml to a global s2 validations.xml, and Struts message resources to global s2 resource.properties.
• ... convert s1 Action classes to session-aware s2 Action classes
• ... convert s1 JSPs to s2 JSPs (non-trivial!)
