Server returns 500 error only when called by Java client using urlConnection/httpUrlConnection
- by user455889
Hi -
I'm having a very strange problem. I'm trying to call a servlet (JSP) with an HTTP GET and a few parameters (http://mydomain.com/method?param1=test¶m2=123). If I call it from the browser or via WGET in a bash session, it works fine. However, when I make the exact same call in a Java client using urlConnection or httpURLConnection, the server returns a 500 error.
I've tried everything I have found online including:
urlConn.setRequestProperty("Accept-Language", "en-us,en;q=0.5");
Nothing I've tried, however, has worked. Unfortunately, I don't have access to the server I'm calling so I can't see the logs.
Here's the latest code:
private String testURLConnection() {
String ret = "";
String url = "http://localhost:8080/TestService/test";
String query = "param1=value1¶m2=value2";
try {
URLConnection connection = new URL(url + "?" + query).openConnection();
connection.setRequestProperty("Accept-Charset", "UTF-8");
connection.setRequestProperty("Accept-Language", "en-us,en;q=0.5");
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
String line;
StringBuilder content = new StringBuilder();
while ((line = bufferedReader.readLine()) != null) {
content.append(line + "\n");
}
bufferedReader.close();
metaRet = content.toString();
log.debug(methodName + " return = " + metaRet);
} catch (Exception ex) {
log.error("Exception: " + ex);
log.error("stack trace: " + getStackTrace(ex));
}
return metaRet;
}
Any help would be greatly appreciated!
