Struts2 sample doesn't work
To help us debug your issue fill in the basic information below using the options provided
Serverless Java Container version: 1.10
Implementations: Struts2
Framework version: Struts 6.0.3
Frontend service: None (plain Lambda exercises the issue)
Deployment method: SAM
Scenario
Build and run the struts sample
Expected behavior
sam local invoke works, the function works deployed to Lambda
Actual behavior
Error finding the required classes in the built ZIP file
Steps to reproduce
-
cd samples/struts/pet-store -
sam build - Populate
test-event.jsonwith content from below -
Note: I had to correct the
Handlerproperty of the function in theSAMtemplate to even get this far. The correct handler string iscom.amazonaws.serverless.proxy.struts2.Struts2LambdaHandler::handleRequest -
sam local invoke -e test-event.json
Full log output
Baseline (no changes to struts.xml)

Analysis
- looked through the ZIP and I think
JacksonLibHandleris expected to be in the JARlib/struts2-rest-plugin-6.0.3.jar - unpacking that JAR, I don't see that class (see below)
- I do see
JacksonJsonHandlerandJacksonXmlHandler

attempt 2: modify bean
- modified the bean that refers to the
JacksonLibHandler, like so:
<bean type="org.apache.struts2.rest.handler.ContentTypeHandler" name="jackson"
class="org.apache.struts2.rest.handler.JacksonJsonHandler"/>
- now rebuild and try
sam local invokeagain - now, there's a different error:

- it would appear that
JacksonLibHandlerdid some sort of multiplexing logic across both the XML and JSON handlers? and that directing Struts at one or the other doesn't help.
