How do you convert WSDLs to Java classes using Eclipse?

In Eclipse Kepler it is very easy to generate Web Service Client classes,You can achieve this by following steps .

RightClick on any Project->Create New Other ->Web Services->Web Service Client->Then paste the wsdl url(or location) in Service Definition->Next->Finish

You will see the generated classes are inside your src folder.

NOTE :Without eclipse also you can generate client classes from wsdl file by using wsimport command utility which ships with JDK.

I wouldn't suggest using the Eclipse tool to generate the WS Client because I had bad experience with it:

I am not really sure if this matters but I had to consume a WS written in .NET. When I used the Eclipse's "New Web Service Client" tool it generated the Java classes using Axis (version 1.x) which as you can check is old (last version from 2006). There is a newer version though that is has some major changes but Eclipse doesn't use it.

Why the old version of Axis matters you'll say? Because when using OpenJDK you can run into some problems like missing cryptography algorithms in OpenJDK that are presented in the Oracle's JDK and some libraries like this one depend on them.

So I just used the wsimport tool and ended my headaches.

You need to do next in command line:

wsimport -keep -s (name of folder where you want to store generated code) urlToWsdl

for example:

wsimport -keep -s C://NewFolder https://www.blablabla.com
