I have JDK 17 and JDK 1.8 on my Windows PC. Why does JDK 17 not contain wsgen.exe in the bin directory while JDK 1.8 contains it? How can I build web applications without wsgen?
Why does JDK 17 not contain wsgen.exe in the bin directory while JDK 1.8 contains it?
Because JEP 320 has removed 9 modules from Java 11, removing alongside tools such as wsgen and wsimport (from jdk.xml.ws).
How can I build web applications without wsgen?
Do you mean how to build? or how to generate/scaffold some code? for building, there are different tools, but for whatever you used wsgen, you could probably refer to maven plugins, some of which you can find here.
