Error when executing Talend ESB has microservice

[DDupont1610375152]

Hello,

I have an error when I execute a Talend 8 ESB route.

This error occur when a route is executed has a micro service (Spring boot).

It works fine when the route is executed in Talend Studio.

Error at runtime : 

java.lang.NoSuchMethodError:

javax.servlet.http.HttpServletMapping javax.servlet.http.HttpServletRequest.getHttpServletMapping()

More precision :
--------------

The route define a REST service.

This error occurs only if this route call another Talend route with a REST service.

What I have analysed :

The method HttpServletRequest.getHttpServletMapping() is only defined for Servlet version 4.0

Servlet version used by Talend 8 is 3.20.

Tomcat used by Talend is version 9.0.84 that use Servlet 4-0

Maybe this can explain the problem.

Hi @DDupont1610375152 ,

as you already suggested, the main issue appears to be a mismatch between the Servlet API version that Talend is using and the version expected by the embedded Tomcat server. Did you find a way to solve it?
