Properties file reading problem

[mallikarjun dontamsetti]

Hi i have an wweb application the connection details for that application are written in a properties file and placed in the same package that my java program uses it and get the connection. But when i deploy it it is Tomcat log are saying that it can not find the connection.properties file why?
My code in getting connections in JAVA file is DBConn.java

 Properties props = new Properties();         
  URL myURL = DBConn.class.getResource("");
  path =  myURL + "connection.properties";
props.load(new FileInputStream(path.substring(6)));

 Driver = props.getProperty("mysql_driver");
url = props.getProperty("mysql_dburl");
      username = props.getProperty("mysql_user");
       password = props.getProperty("mysql_password");

You could also use the ResourceBundle class to open the properties file, and you don't need to specify the .properties extension. An example can be seen here: http://koenaerts.ca/websphere-global-properties-files/

I'd say it is better to use a ResourceBundle only for properties of the presentation layer (i.e. labels that are displayed in a web page), or resources that are locale-specific.

Mallikarjun, try the following:

// Define here the path to your .properties file. If your file is in, say, com.mallikarjun.resources.file.properties,
// then the path will look like /com/mallikarjun/resources/file.properties.
final String path = "/com/mallikarjun/resources/file.properties";

final Properties properties = new Properties();
final InputStream stream = getClass().getResourceAsStream(path);
try {
    properties.load(stream);
} catch (final IOException exception) {
    final String message = "The following exception occurred: " + exception.getMessage();
    throw new RuntimeException(message, exception);
}

props.load(new FileInputStream(path.substring(6)));

Why substring(6)???

If I had a file reading problem I would certainly log or print to System.out the path I was trying to open.

Agreed.
