Loading properties file from WEB-INF folder in a log4j appender

We're writing a custom log4j appender for our application. The appender should log its events to a database. Now the problem I'm having is setting up the database connection. Our jdbc settings are in a file called jdbc.properties which is located directly under the WEB-INF folder.

I've tried accessing the properties file using the following code 

InputStream stream = Thread.currentThread().getContextClassLoader()
                    .getResourceAsStream("jdbc.properties");

... but stream results in being null. Any ideas how I can load a properties file from the WEB-INF folder in a log4j appender without moving the properties file to another location?

Solution

  • May be you can try,

     String  path =Thread.currentThread().getContextClassLoader().getResource("/").toURI().resolve("../jdbc.properties").getPath();
 Properties ps=new Properties();
 ps.load(new FileInputStream(path));
