Use the Jakarta SOAP with Attachments API technology in the Java class library to process SOAP messages

Use the Jakarta SOAP with Attachments API technology in the Java class library to process SOAP messages Soap (Simple Object Access Protocol) is a communication protocol for exchanging structured data on the Internet.You can use the Jakarta Soap with Attachments API technology in the Java Library to process SOAP messages.The API provides a simplified way to create, send and receive SOAP messages, and support additional data. The following is an example code that uses Jakarta SOAP with Attachments API to process SOAP messages: First, you need to introduce the required class library: import javax.activation.DataHandler; import javax.activation.FileDataSource; import javax.xml.soap.*; import java.io.File; import java.io.FileOutputStream; Then, create a SOAP message builder: SOAPMessage soapMessage = MessageFactory.newInstance().createMessage(); SOAPPart soapPart = soapMessage.getSOAPPart(); SOAPEnvelope envelope = soapPart.getEnvelope(); You can add the necessary heads and text information to the SOAP message, as well as additional data: // Add head information SOAPHeader header = envelope.getHeader(); // Add text information SOAPBody body = envelope.getBody(); // Add additional data AttachmentPart attachment = soapMessage.createAttachmentPart(new DataHandler(new FileDataSource("attachment.txt"))); attachment.setContentId("attachment1"); soapMessage.addAttachmentPart(attachment); Send SOAP message to the designated server: // Specify the URL of the server String endpointURL = "http://example.com/soap-endpoint"; SOAPConnectionFactory soapConnectionFactory = SOAPConnectionFactory.newInstance(); SOAPConnection soapConnection = soapConnectionFactory.createConnection(); // Send a message SOAPMessage response = soapConnection.call(soapMessage, endpointURL); Finally, you can deal with the received response: // Treatment response message SOAPBody soapResponseBody = response.getSOAPBody(); // Analyze the data in the response String result = soapResponseBody.getTextContent(); System.out.println("Response: " + result); The above is a simple example of using Jakarta SOAP with Attachments API technology to process SOAP messages in the Java class library.By using this API, you can easily create, send and receive SOAP messages, and support additional data.
