Hi,

 

You can invoke the REST service that you have created in Apex by creating a new HTTPPut object in java and using the your REST service URL that you have defined in your REST service.

 

Here is an example:

 

public void RestMethod1(){
HttpClient httpclient = new DefaultHttpClient();
System.out.println("Creating HTTP Client");


HttpPut put = new HttpPut("https://instance.salesforce.com/services/apexrest/Account/<sample account id>");
HttpResponse response = null;


// set the token in the header
System.out.println("Setting authorization header");
get.setHeader("Authorization", "OAuth 00D50000000IoZ6!AQYAQJ4Q.w9jmFMZJNRlw54y4RuUxfQYGGJzebS3LFL2xEgmvUaWs7xhS6OJrkcO5jw2zPR1I3xhuiNVVXWaiKU_7iibsZ8J");

try{
System.out.println("Executing Put request");
response = httpclient.execute(put);
HttpEntity entity = response.getEntity();

}catch(Exception e){
      e.printStackTrace();
}
}

 

The URL specified when creating the HTTPPut is what you have defined in the:

@RestResource(urlMapping='/Account/*') at the top of your REST class in APEX along with the standard REST URL for salesforce like https://instance.salesforce.com/services/apexrest

 

Hope it is helpful.

Thanks but I am looking to invoke external services from within salesforce.

Hi,

 

Your original issue said, you wanted to create a REST service in apex and then invoke it from Java, now you are saying you want to invoke external services from within salesforce. Can you please clarify:

 

Nevertheless, you can invoke any external webservice or even an web service created in apex rest like this:

 

Http h = new Http();
HttpRequest req1 = new HttpRequest();
req1.setEndpoint('<end point of your REST service>');
req1.setMethod('PUT');
HttpResponse res1 = null;
res1 = h.send(req1);
system.debug('%%%%%%%%%%%%%%%%%%%%%% ' + res1.getBody());

 

Regards,

Sankalp

Let me know ,if that helps you  .

 

HttpPut: Defines the function to be used with the endpoint with HTTP PUT POST

 

@HttpPut
      global static String updateCase(RestRequest req) {
          String companyName = req.params.get('companyName');
          Account company = [ Select ID, Name, Email__c, BillingState from Account where Name = :companyName];
         
          Attachment a = new Attachment();
          a.ParentId = company.Id;
              a.Name = 'test.png';
          a.Body = req.requestBody;
           
          insert a;
           
          return 'Attachment added';
      }

 

Kind Regards,
