Do not include. This lib will load jar from file system or any other location. It will dedicate a class loader for the jar to make sure there are no library conflicts. Users will be able to create any object from the loaded jar and call any method on it. This lib was designed to load jars compiled in Java 8 from the code base that supports Java 7. java urlclassloader remove url

Creates a new instance of URLClassLoader for the specified URLs and default parent class loader. static URLClassLoader: URLClassLoader. newInstance (URL[ urls Retrieves the value of the designated column in the current row of this ResultSet object as a java. net. URL object in the Java programming language. URL: Method Detail getResourceAsStream. Returns an input stream for reading the specified resource. close. Closes this URLClassLoader, so that it can no longer be used to load new classes addURL. Appends the specified URL to the list of URLs to search for classes and resources. getURLs.

EDIT (thanks to @Hot Licks): OK, so it isn't exactly what the OP has asked for. It doesn't free up all the resources, or make the resources and the loader collectible. It simply prevents the loading of more resources using the class loader. Assume, that you have a JAR with the following content: C1. class x2. jar (which contains C2. class) C1 needs classes in so it constructs a URLClassLoader with that URL but the CL does not find the classes When I run that jar using java jar artifact. jar it is able to load classes from that main jar and from all jars in the libs directory. However if I ask the system property java. class. path it will only list the main jar. In order to better understand how things works in Java, I'd like to know if I can dynamically add, at runtime, a directory to the class path. For example, if I launch a. jar using java jar mycp.
