Introduction

This tutorial will show you how to publish a service written in Java. Although InstantSOAP is highly configurable, in this case, we are going to use the simplest defaults. It assumes that you have installed Java, Tomcat and Maven, as described in the requirements . If you have not tried the 10 minute introduction, you might like to start there.

Generate a Skeleton

InstantSOAP uses the maven tool for building. In this case, we are going to use an "archetype" to generate the base structure. This is a matter of typing the following command. 
        mvn archetype:create -DarchetypeGroupId=uk.ac.ncl.cs.instantsoap \
            -DarchetypeArtifactId=archetype-escience-tool \
            -DarchetypeVersion="2.0" \
            -DgroupId=uk.org.your.url.here  \
            -DartifactId=your_service_name
Depending on your operating system you may have to type this in on one line without the "\"'s. The last two lines should be replaced with something specific to your service.

Customising the code

Find the file called HelloWorldProcessor.java. The exact location will depend on the values you used in the last section. Find this section. 
      // this is the guts of the processor -- in this case, it does very little.
      public String process(String input) throws JobExecutionException
      {
         return "hello " + input;
      }
Change this to: 
      // this is the guts of the processor -- in this case, it does very little.
      public String process(String input) throws JobExecutionException
      {
         return "goodbye " + input;
      }
Find the file called HelloWorldProcessorTest.java. Replace this section: 
      public void testProcess() throws Exception
      {
        HelloWorldProcessor processor = new HelloWorldProcessor();
        Assert.assertEquals("hello world", processor.process("world"));
      }
with this: 
      public void testProcess() throws Exception
      {
        HelloWorldProcessor processor = new HelloWorldProcessor();
        Assert.assertEquals("goodbye world", processor.process("world"));
      }
You can just delete the test class if you prefer, although tests are good practice.

Compile and Deploy

Move to the same directory as the file pom.xml. Now type 
        mvn install
This should create a war in the directory target called your_service_here.war. You can now deploy this as described elsewhere . Finally, check that the service is running by navigating to: http://localhost:8080/your_service_here-SNAPSHOT/services/instantsoap/applications?wsdl

Conclusions

Deploying a service should be relatively straight-forward. For many users, the steps shown here should be sufficient for most purposes. The files created in the first step have additional documentation describing what each does for those who wish to configure InstantSOAP further.
