Exception when our API path ends with the <x>.<y> (.../versions/v1.0) format?

[ashokkumar-subburaj]

Serverless Java Container version: 1.9

Implementations: Spring Boot 2

Framework version: SpringBoot 2.7.7.RELEASE

Frontend service: REST API

Deployment method: SAM

Java version : Java11

Scenario

We have few endpoints implemented one of which endpoint ends with the format (BASE_URL)/versions/*.* . For example as mentioned in the summary our url ends with the GET {BASE_URL}/.../versions/v1.0.
Our get versions spring boot implementation code is something like the below.
@GetMapping(value = "/../{path_variable}/versions/{input}")
Container is trying to resolve this as a file rather than the normal REST endpoint and failing with the exception.

Expected behavior

It should resolve correctly and implementation code should be called.

Actual behavior

java.lang.NoClassDefFoundError: com/sun/activation/registries/LogSupport at javax.activation.MimetypesFileTypeMap.<init>(MimetypesFileTypeMap.java:100) at com.amazonaws.serverless.proxy.internal.servlet.AwsServletContext.getMimeType(AwsServletContext.java:137)

Thanks for reporting this issue. We are looking into it.

Hi @ashokkumar-subburaj. I was trying to reproduce your error, but I wasn't able to do so with the setup you described in the description. Do you have a full project where the problem can be reproduced so we can try it out? (Or maybe try to reproduce starting with our sample project) There might be come other configuration that's causing this issue.

On a side note, and I don't know if it will help in your case, but the exact error that you're seeing also seems to be related to a missing dependency as described here: jakartaee/jaf-api#60. You could try to add what's mention there (adding the dependency com.sun.activation:jakarta.activation) to see if then your application works correctly, while we try to reproduce the rest of your problem.

[ashokkumar-subburaj]

I'll try adding this dependency and update here.

Sorry for the late reply. Adding the above dependency com.sun.activation:jakarta.activation worked for me. Thanks for the help @mbfreder @valerena
