Apache Axis (Apache eXtensible Interaction System) is an open-source, XML based Web service framework. It consists of a Java and a C++ implementation of the server, and various utilities and APIs for generating and deploying Web service applications. Using Apache Axis, developers can create interoperable, distributed computing applications. Axis development takes place under the auspices of the Apache Software Foundation.
When using the Java version of Axis there are two ways to expose Java code as Web service. The easiest one is to use Axis native JWS (Java Web Service) files. Another way is to use custom deployment. Custom deployment enables you to customize resources that should be exposed as Web services.
See also Apache Axis2.
JWS files contain Java class source code that should be exposed as Web service. The main difference between an ordinary java file and jws file is the file extension. Another difference is that jws files are deployed as source code and not compiled class files.
The following example is taken from http://axis.apache.org/axis/java/user-guide.html#Publishing_Web_Services_with_Axis . It will expose methods add and subtract of class Calculator.
Once the Axis servlet is deployed, you need only to copy the jws file to the Axis directory on the server. This will work if you are using an Apache Tomcat container. In the case that you are using another web container, custom WAR archive creation will be required .
JWS Web service is accessible using the URL http://localhost:8080/axis/Calculator.jws . If you are running a custom configuration of Apache Tomcat or a different container, the URL might be different.
