How to Connect to SOAP From Java

Powering the back-ends of many different kinds of Web applications are SOAP application programming interfaces. SOAP is a messaging protocol used to send and retrieve documents programmed in extensible markup language, or XML. SOAP interfaces provide a set of conditions and rules that must be met in order for the application programming interface to generate a response or an item of data as an output. The programming language Java can be used to connect to SOAP interfaces and pass data between servers and users.

Instructions

1. Create a new Java application by launching your development platform or a text editing program to begin coding.

2. Initiate the importation of SOAP data with the following code:

   import.javax.xml.soap.SOAPConnectionFactory;

   import javax.xml.soap.SOAPConnection;

3. Create a public class called SOAPTip that will connect to the SOAP interface:

   public class SOAPTip {

   public static void main(String args[]) {

   try {

   SOAPConnectioFactory soapConnFactory=

   SOAPConnectionFactory.newInstance();

   SOAPConnection connection =

   soapConnFactory.createConection();

4. Close the SOAP connection by using the following lines of code:

   connection.close();

   }
