Web service can be created in Salesforce for external system calls, and the calling interface can be provided externally as soap or rest, followed by a detailed description of how to create a Web in soap Service and make a simple call with a program.

1): Create the following class in Salesforce

"NOTE: If you want to make it a Web service, then class must be defined as global, with the specific method of webService static modifier"

"The code omits the specific implementation of the Generateaccountfromxmlinfo method, see the details:"

Global class Sfaccountwebservice {
    webService static string Upsertaccount (String accountxmlinfo) {
        account CURRENTACC = Generateaccountfromxmlinfo (accountxmlinfo);
            acc = [Select Id from Account a Where AccountNumber =: Currentacc.accountnumber];
            if (ACC!= null) {
       = Acc. Id;
            Upsert CURRENTACC;
            Return ' true ';
        catch (Exception ex) {return
            ' false ';    
    private static Account Generateaccountfromxmlinfo (String accountxmlinfo) {account
        CURRENTACC = new account ();
        Parse the XML info to generate the account Object return

2): after saving the class above, we found the class just saved in the setup--> build--> develop--> apex classes. We will find that there is a WSDL option in the corresponding action, which is Salesforce by default to convert the class of the Web service into a WSDL file. As shown in the following figure
