Got problem in tomcat while read xml file..

Question

hi' i just wondering, why i always got his exception, i just want to read this file
java.io.FileNotFoundException: C:\Program Files\netbeans-5.5\enterprise3\apache-tomcat-5.5.17\bin\dbconfig.xml (The system cannot find the file specified)
     at java.io.FileInputStream.open(Native Method)......How to read dbconfig.xml??
Right now i put dbconfig.xml in /webapps/myapp/web-inf/classes/dbconfig.xml. but i always got that exception, why??
if i put my dbconfig.xml in apache-tomcat-5.5.17\bin directory (see exception...), i got no exception.
So, is there anyway to read dbconfig.xml while i put it in /webapps/myapp/web-inf/classes/ directory?
This is my code :
public UserWrapper(){
        builder = new SAXBuilder();
        try {
            doc = builder.build(new File("dbconfig.xml"));
            rootElement = doc.getRootElement();
            System.out.println(rootElement.getChildText("db-driver"));
        } catch (JDOMException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace(); 
    }   Thanks a lot..

The JVM looks for files relative to the pwd or directory in which it was started. For Tomcat it is the bin directory. That is why it can find dbconfig.xml in the bin directory but not the classes directory.
You have two choices.
1; give the path to the file inth eclasses directory. You can use the ServletContext getRealPath method to build this path.
2: Since the file is in the classpath you can use the Class getResourceAsStream method to get an InputStream to the file. Then see if the SAXBuilder class has an api that takes an InputStream.
