Follow below simple steps to create and deploy simple Web Service and Web Service Client in Eclipse IDE.
Step-1
Install Apache Tomcat and add it to Eclipse in Server Tab – I’m using Tomcat version 9.0.10.
Step-2
Create a Dynamic Web Project (name: CrunchifyWS)
Step-3
Create java file under /src folder. Right Click /src folder -> New -> Class.
- Package:
crunchify.com.web.service - Name:
CrunchifyHelloWorld.java
Step-4
Open CrunchifyHelloWorld.java file and create simple main method.
package crunchify.com.web.service;
/**
* @author Crunchify.com
*/
public class CrunchifyHelloWorld {
public float addValue(float value) {
return (value + 10);
}
public float subtractValue(float value) {
return (value - 10);
}
}
Step-5
- Right Click on file
CrunchifyHelloWorld.java -> Web Services -> Create Web Service - Select options as mentioned in below diagram.
- Click finish
Step-6
It may take some time to finish all processes and you should see new project “CrunchifyWSClient” created. Here is a final project structure:
Step-7
CrunchifyWS and CrunchifyWSClient both projects should be automatically deployed to server.
Also, Eclipse automatically opens Web Service Test Client Window with URL: http://localhost:8080/CrunchifyWSClient/sampleCrunchifyHelloWorldProxy/TestClient.jsp?endpoint=http://localhost:5922/CrunchifyWS/services/CrunchifyHelloWorld
Step-8
Now click on addValue(float), subtractValue(float) and provide an input to check updated result.
And you are all set. Do let me know if you see any difficulty with these steps.
Are you getting below error after clicking Invoke button?
Result Exception: java.net.ConnectException: Connection refused (Connection refused) Message: ; nested exception is: java.net.ConnectException: Connection refused (Connection refused)
Follow below steps:
- Right click on Tomcat
- Click Add and Remove to see application added
- Click Clean…
- Click Publish
- Click Restart
How to rerun WebService after restarting Application or later?
Here is a handy URL: http://localhost:8080/CrunchifyWSClient/sampleCrunchifyHelloWorldProxy/TestClient.jsp
