Java WebService Simple Instance

First, the preparation work (the following is the use of the tool for this example)

1, MyEclipse10.7.1

2. JDK 1.6.0_22

Second, create the service side

1. Create "Web Service Project", named "Theservice".

2. Create the "class" class, named "Servicehello", located under the "Com.hyan.service" package.

3, write the method for the client to call, that is, compile the method code.

4, to compile

Description: If compilation fails, set the JDK referenced by this project to version 1.6.0_17 or later

5. Test results

Test Address:http://localhost:9001/Service/ServiceHello?wsdl

Third, generate the client

1 . Create "Web Service Project", named "theclient".

2. The command Prompt window executes the build command.

format: wsimport-s "src directory"- p "generated class package name" -keep "WSDL publishing Address"

Example:

Wsimport-s g:\\workspace\\webservice\\theclient\\src-p Com.hyan.client-keep http://localhost:9001/Service/ servicehello?wsdl

Description

1) "src directory" address cannot contain spaces

2)"WSDL publishing Address" Don't miss "? wsdl "

3, refresh the project, check the generated class

Iv. final Test

1. Create the "class" class, named "Servicetest", located under the "Com.hyan.test" package.

2, write the test method, call the service-side method, and print the returned results.

Five, matters needing attention

1, JDK version too low problem

the report resembles the following exception:Runtime Modeler Error:wrapper class Com.hyan.service.jaxws.GetValue is not found. Do you run the APT to generate them?

Reason: JDK version less than 1.6.0_17

Workaround: Adjust the JDK version referenced by this server-side project as a high-build JDK installed

2. Generate command path with whitespace issues

the report resembles the following exception:directory not found:g:\svn_file\gb\05

Cause: The client src path must not contain spaces

Workaround: recreate the client under a folder that does not contain a space path.

3. Incomplete command generation

report an exception similar to the following: [ERROR] failed.noservice=could not find Wsdl:service in the provided WSDL (s):

cause: "? wsdl" is missing at the end of the build command

Workaround: fill up.

An example of an incomplete error command:

Wsimport-s g:\\workspace\\webservice\\theclient\\src-p Com.hyan.client-keep Http://localhost:9001/Service/ServiceHello

Examples of correct and complete commands:

Wsimport-s g:\\workspace\\webservice\\theclient\\src-p Com.hyan.client-keep http://localhost:9001/Service/ servicehello?wsdl
