How Do I Access Files Embedded in a JAR Using Java?

Accessing Files from JARs in Java

To access files embedded within JARs in a Java application, utilize the following solution:

Utilize the getResourceAsStream() method.

InputStream input = getClass().getResourceAsStream("/classpath/to/my/file");

• / Signifies Classpath: The path commences with a / symbol, representing the classpath rather than the file system.
• Classpath Path Structure: If your file is located within the "org.xml" classpath under the name "myxml.xml," the path should be "/org/xml/myxml.xml."
• InputStream Usage: The InputStream instance enables access to the file's contents. It can be wrapped into a Reader for convenience.
