Running sendGrid.api(request); throws an java.lang.IllegalAccessError

[russellraed]

Running sendGrid.api(request); throws an java.lang.IllegalAccessError. See code below.

SendGrid sg = new SendGrid(this.apiKey);
Request request = new Request();
try {
    request.setMethod(Method.POST);
    request.setEndpoint("mail/send");
    request.setBody(mail.build());

    Response response = sg.api(request); // <-- Error Here

    System.out.println(response.statusCode);
    System.out.println(response.body);
    System.out.println(response.headers);

} catch (IOException ex) {
    throw ex;
}

I'm using sendgrid-java version 3.1.0 and java-http-client 3.0.0 (if that also helps).
I've attached the stack trace below.

Thanks for reporting this @russellraed!

I have added this to our backlog for a fix.

[russellraed]

Jar file from project's git page seems to work. Not sure why the maven one doesn't.

[joegalley]

I had the same issue until I used version 3.1.0 of sendgrid-java and version 2.3.4 of java-http-client.

[thinkingserious]

@joegalley,

Thanks for chiming in! Did you use maven for your install?

[thinkingserious]

@russellraed,

Thanks for following up!

[rcarrillodev]

I have the same problem using 3.0.9

I'm using the example for making tests:

private void sendMail(String token) throws Exception {
        Email from = new Email("mail@mail.com.mx");
        String subject = "Mail TEST";
        Email to = new Email("mail@gmail.com");
        Content content = new Content("text/html", "Mail tests");
        Mail mail = new Mail(from, subject, to, content);

        SendGrid sg = new SendGrid("<API KEY>");
        Request request = new Request();
        try {
            request.setMethod(Method.POST);
            request.setEndpoint("mail/send");
            request.setBody(mail.build());
            Response response = sg.api(request);
            System.out.println(response.getStatusCode());
            System.out.println(response.getBody());
            System.out.println(response.getHeaders());
        } catch (IOException ex) {
            throw ex;
        }
    }

@Rafuru,

Can you please try v3.1.0?

[bqcuong]

try this, it works for me with sendgrid-java:3.1.0 and java-http-client:4.0.0

        SendGrid sendGrid = new SendGrid(SENDGRID_APIKEY);
        Request request = new Request();

        try {
            request.setMethod(Method.POST);
            request.setBody(mail.build());

            // make request
            request.setBaseUri(sendGrid.getHost());
            request.setEndpoint("/" + sendGrid.getVersion() + "/mail/send");
            for (String key : sendGrid.getRequestHeaders().keySet())
                request.addHeader(key, sendGrid.getRequestHeaders().get(key));

            // send
            Response response = sendGrid.makeCall(request);
            System.out.println("status code: " + response.getStatusCode());
            System.out.println("body: " + response.getBody());
            System.out.println("headers: " + response.getHeaders());
        } catch (IOException ex){
            ex.printStackTrace();
        }

[mgooty]

sendGrid.makeCall(request) method works but the issue is when you invoke sendGrid.api(request)

[thinkingserious]

Hi @mgooty,

What version of the SDK are you using?

[mgooty]

Hi @thinkingserious

I am using com.sendgrid.sendgrid-java:3.1.0 and com.sendgrid.java-http-client:4.0.0. The problem is api() method is accessing the private variables from com.sendgrid.Request class. Following is the code snippet:

Request req = new Request();
req.method = request.method;
req.baseUri = this.host;
req.endpoint = "/" + version + "/" + request.endpoint;
req.body = request.body;
req.headers = this.requestHeaders;
req.queryParams = request.queryParams;

[thinkingserious]

Hi @mgooty,

Could you please provide a complete code snippet so that I may try to reproduce?

I can not reproduce using the example code:

import com.sendgrid.*;
import java.io.IOException;

public class Example {
  public static void main(String[] args) throws IOException {
    Email from = new Email("dx@sendgrid.com");
    String subject = "Hello World from the SendGrid Java Library!";
    Email to = new Email("elmer.thomas@sendgrid.com");
    Content content = new Content("text/plain", "Hello, Email!");
    Mail mail = new Mail(from, subject, to, content);

    SendGrid sg = new SendGrid(System.getenv("SENDGRID_API_KEY"));
    Request request = new Request();
    try {
      request.method = Method.POST;
      request.endpoint = "mail/send";
      request.body = mail.build();
      Response response = sg.api(request);
      System.out.println(response.statusCode);
      System.out.println(response.body);
      System.out.println(response.headers);
    } catch (IOException ex) {
      throw ex;
    }
  }
}

Run with the following command:

javac -classpath ../repo/com/sendgrid/3.1.0/sendgrid-3.1.0-jar.jar:. Example.java && java -classpath ../repo/com/sendgrid/3.1.0/sendgrid-3.1.0-jar.jar:. Example

Thanks!

[mgooty]

@thinkingserious Please find the code below:

import com.sendgrid.*;

  public class Test {

  public static void main(String[] args) throws Exception {
	SendGrid sendgrid = new SendGrid("KEY");
	
	Email from = new Email("dx@sendgrid.com");
        String subject = "Hello World from the SendGrid Java Library!";
    
        Email to = new Email("elmer.thomas@sendgrid.com");
        Content content = new Content("text/plain", "Hello, Email!");
    
        Mail mail = new Mail(from, subject, to, content);
	
	Request request = new Request();
	request.setMethod(Method.POST);
	request.setBaseUri(sendgrid.getHost());
        request.setEndpoint("/" + sendgrid.getVersion() + "/mail/send");
        request.addHeader("Authorization", "Bearer " + "KEY");
	request.setBody(mail.build());
	
	Response response = sendgrid.api(request);
	System.out.println(response.getStatusCode());
  }
}

Following error is thrown:
