Struts 2 migration tools include the notions of
- bridge objects to utilize existing s1 resources, and
- utilities to convert resources to s2 equivalents.
|
This is a whiteboard describing tools that volunteers might write, given sufficient interest. |
Dual Processor, Shared Resources
- A s2 TextProvider that retrieves messages from the s1 MessageResources instance in the servlet context
- 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 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!)
