Problem with loading properties from deployment.properties

[Sugantha Jeevankumar]

I have an application in which various properties like Xms and Xmx values are set while the user logs in. The file <User's HOME>/Application Data/Sun/Java/Deployment/deployment.properties is loaded into a Properties object and the values are set from there ..

Properties properties = new Properties(); 
try {
    properties.load(new FileInputStream("C:\Documents and Settings\<username>\Application Data\Sun\Java\Deployment\deployment.properties")); 
    String jreParams = properties.getProperty("deployment.javapi.jre.1.5.0_11.args")
} 
catch (IOException e) { 
    e.printStackTrace();
} 

For some reason, the value for key, "deployment.javapi.jre.1.5.0_11.args" (line #:4) is always returned as null. When I check the properties file it does contain a value for the corresponding key. Is there any reason why this does not work. Any suggestions are welcome. Thanks in advance.

Does the underscore character generally work as a property name?

Yes.. Normally, "." is used to separate words in a property's key. I changed them to underscores in a sample file and it works fine.

I am just thinking.. Can this be an issue with multiple JREs being present in a system and the application having trouble reading the JRE parameters of a specific version of JRE. I am not sure. Any pointers or suggestions are appreciated. Thanks in advance.
