Java Beans Interview Questions and Answers
Question: Why do I get a NullPointerException when loading a JAR file into the BeanBox?Answer: Usually this is because of a mistake in the JAR file being loaded. In the meantime, typical errors include:► The MANIFEST file uses classes using the wrong file separator ("/" should be used in all platforms). ► The MANIFEST file refers to classes in a package but the actual .class files are not really in that package. |
