Question about cutom tag jars on Tomcat

Question

I have written a custom tag for data connection in Java and wrote a TLD to use it. My problem is a I have three applications that all use it, so I put the jar file in my CATALINA_HOME/common/lib and the tld finds the jar but the jar has a properties file it uses to get the DB name and user names. The jar can not find the properties file, I tried putting it in the common/lib/, I put it in the common/ and I also tried in the APP_DIR/WEB-INF/ and it still can not find them. Is there a place I can put the properties file that tomcat will have it available for the jar file.
Thanks in advance

Put the properties file inside the jar file. Then you can load it from your code using the classloader. Lets say you put the properties file in a subdirectory "props" inside the jar, you can then load it using this code:
InputStream is = this.getClass().getClassLoader().getResourceAsStream("props/db.properties");
Properties props = new Properties();
props.load(is);
is.close();Assuming you name your file "db.properties" of course.
