We have an app with several JavaEE servlets (ie they use the javax.servlet package naming) but have been forced into upgrading our container to the newer Jakarta EE classes (ie jakarta.servlet) due to a number of technical issues too long to list.
We are not at liberty to rewrite the javax.servlets because the servlet classes come from another library to which we don't have access.
Before I start to implement the necessary adapters from javax to jakarta, has anyone already implemented them? I've searched but surprisingly haven't found anything.
