getSystemResourceAsStream() returns null
- by Hitesh Solanki
Hiii...
I want to get the content of properties file into InputStream class object using getSystemResourceAsStream(). I have built the sample code. It works well using main() method,but when i deploy the project and run on the server, properties file path cannot obtained ... so inputstream object store null value.
Sample code is here..
public class ReadPropertyFromFile {
public static Logger logger = Logger.getLogger(ReadPropertyFromFile.class);
public static String readProperty(String fileName, String propertyName) {
String value = null;
try {
//fileName = "api.properties";
//propertyName = "api_loginid";
System.out.println("11111111...In the read proprty file.....");
// ClassLoader loader = ClassLoader.getSystemClassLoader();
InputStream inStream = ClassLoader.getSystemResourceAsStream(fileName);
System.out.println("In the read proprty file.....");
System.out.println("File Name :" + fileName);
System.out.println("instream = "+inStream);
Properties prop = new Properties();
try {
prop.load(inStream);
value = prop.getProperty(propertyName);
} catch (Exception e) {
logger.warn("Error occured while reading property " + propertyName + " = ", e);
return null;
}
} catch (Exception e) {
System.out.println("Exception = " + e);
}
return value;
}
public static void main(String args[]) {
System.out.println("prop value = " + ReadPropertyFromFile.readProperty("api.properties", "api_loginid"));
}
}
