check webresource status

   
Introduction:

Sometimes you want to know if a service is responding correctly before you give it the actual task.
With a small piece of code you can test if the response you get is an apropriate one.

The imports are from the :

<dependency>
<groupId>commons-httpclient</groupId>
<artifactId>commons-httpclient</artifactId>
<version>3.1</version>
</dependency>

The example:

boolean isUp = false;
HttpClient client = new HttpClient();
               //********************************************************
//Optional for https sessions. You can run it through a trusted proxy
        // to get the certificates.
//client.getHostConfiguration().setProxy("MyProxy", MyProxyPort);
                //********************************************************
     GetMethod method = new GetMethod("http://www.google.nl/");
     try{
         client.executeMethod(method);
         if(method.getStatusCode()==200){
                     isUp = true;
                 }


     }catch(Exception e) {
         System.err.println(e);
     }finally {
         method.releaseConnection();
     }
return isUp;

Conclusion:

It is quiet easy to check before you send your query or data to a url to check if it will respond correctly.
So have fun!
