How Can I Access a Resource File (e.g., XML) Inside a Java JAR?

Accessing a Resource File from Within a Java JAR

You're encountering issues loading an XML file from a JAR file. Here's the appropriate solution:

Instead of using FileReader, which is not suitable for reading resources from a JAR, utilize java.lang.Class.getResourceAsStream(String). The correct way to read the XML file is as follows:

URL url = getClass().getResourceAsStream("/xxx/xxx/xxx/services.xml");

This method returns an InputStream which allows you to access the resource file's contents as a stream. You can then parse the XML file using an appropriate XML parsing library.
