Roborio Connecting to Raspberry Pi

[mkmeral]

I am right now trying to get message from raspberry pi using roborio(java). I have configured Raspberry as web server, and i access to a file from it. In my computer (not wpilib) it works, I can get the data as I should normally do. However, when, try to upload the code below to the roborio i get the error below. Any suggestions? public void networking(){ // TODO Auto-generated method stub

try{
String wholetext = "";
URL oracle = new URL("http://10.41.91.109/a");
URLConnection yc = oracle.openConnection();
BufferedReader in;
in = new BufferedReader(new InputStreamReader(
yc.getInputStream()));

String inputLine;
while ((inputLine = in.readLine()) != null)
wholetext += inputLine;
in.close();
SmartDashboard.putString("Deger", wholetext);
}catch(Exception e){
SmartDashboard.putString("NETWORK:", e.getMessage());
}

}

Install a JDK (http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html)

It's already installed. I am also developing other apps on this pc, and they work fine. Also I tried the same code on eclipse console (java app) and it worked.So I do not think there's problem with jdk. Also without the jdk installed, eclipse gives an error at startup

Ok, then you just need to fix your environment variables. Change JAVA_HOME to the location of your jdk (C:\Program Files\Java\jdk_<version>). Then you should probably also edit your PATH for good measure: remove C:\Program Files\Java\jre_<version>\bin if it's there and add C:\Program Files\Java\jdk_<version>\bin and C:\Program Files\Java\jdk_<version>\jre\bin

What is the stacktrace of the error? Without that we can't tell what the problem is.
