PostJSON in ThingWorx 9.0 Extension SDK

[nmilleson]

Has anybody been successful using the ContentLoader functions in TWx 9.0 Extension SDK?  I've been following this example and this javadoc but I keep getting a null pointer exception.  Just to test my sanity, I used the same url, header, and content information inside a Composer service and I was successful.  I've attached the stack trace and the code I'm using is:

public Boolean myService() throws Exception {
	Boolean verify = false;	
		
	ContentLoader verifyCheck = new ContentLoader();  
		
		
	String url = "https://postman-echo.com/post";
		
        JSONObject content = new JSONObject("{\"meta\":{\"key\": \"" + "abc" + "\"}}");
        String username = null;
        String password = null;
        JSONObject headers = null;
        Boolean ignoreSSLErrors = null;
        Boolean withCookies = null;
        Double timeout = null;
        Boolean useNTLM = null;
        String workstation = null;
        String domain = null;
        Boolean useProxy = null;
        String proxyHost = null;
        Integer proxyPort = null;
        String proxyScheme = null;
        
        try {         	
           _logger.warn("URL in myService(): " + url.toString()); 
           _logger.warn("Content in myService(): " + content.toString()); 
        	 
        verifyCheck.PostJSON(url, content, username, password, headers, 
          ignoreSSLErrors, withCookies, timeout, useNTLM, workstation, domain, useProxy, 
          proxyHost, proxyPort, proxyScheme);        	
        }
        catch(Exception e)
        {
        	StringWriter sw = new StringWriter();
        	PrintWriter pw = new PrintWriter(sw);
        	e.printStackTrace(pw);
        	
        	_logger.error("Exception in myService(): " + sw.toString()); 
        }
		return verify;
	}

@slangley ,

Thanks for the reply.  I believe I found the issue.  In the example that I linked, all of the Boolean values are set to null.  I changed them all to false instead and that seems to have fixed the issue.  The PTC example may need to be updated.
