loading a properties file

[vinitha simon]

I have a properties file in the same folder as my java class. I have tried the following code to load it, but it fails. I get an uncaught NullPointer Exception.

main.java
--------------------------------------------------------------------------------------------------
Properties properties = new Properties();
InputStream stream = null;
try {
stream = getClass().getResourceAsStream("/test.properties");
properties.load(stream);
} catch (IOException e) {
}

and my test.properties file is as follows
---------------------------------------------------------------------------------------------------
subject=Test Mail
body=Dear ${0}:\n\nThis is a test mail.

and the code using message formatter to substitute the values is as follows :

main.java
--------------------------------------------------------------------------------------------------------
String temp=properties.getProperty("body");
java.text.MessageFormat formatter = new java.text.MessageFormat("");
formatter.applyPattern(temp);

Object[] messageArguments = {"Jim Berkley"};

String output = formatter.format(messageArguments);


for some reason, this does not work.... Any help is appreciated!!

TIA

From Class.getResourceAsStream javadoc

...an absolute resource name is constructed from the given resource name using this algorithm:

If the name begins with a '/' ('\u002f'), then the absolute name of the resource is the portion of the name following the '/'.
Otherwise, the absolute name is of the following form:
modified_package_name/name
Where the modified_package_name is the package name of this object with '/' substituted for '.' ('\u002e').

As your properties file is in the same directory as your class file, you need it to be prefixed by the modified package name, so you need to remove the '/' at the start
