eclipse no java virtual machine found

method throws an exception, The Virtual Machine considers this Java method to throw an exception. (5) When executing a program, find the loaded class in the method area through the object reference. If no loaded class is found, find the bytecode (class name. class), and load it into the method area.During execution, t

class, because the Testapplet is not in the load path of the system loader, so the system loader does not find this class, and there is no load success.Then the ACL itself loads the testapplet. The ACL successfully found the Testapplet.class file through the network and imported it into the JVM. During the load process, the JVM discovers that Testappet is inherited from the superclass Java.applet.Applet.So the JVM calls the ACL again to load the Java

The production package reports a path error that cannot be found in the development environment. Modifying the configuration can solve the problem, but will it be annoying if path is involved in every online change? Or, how can this be tolerated? The solution is as follows: For production security, it is better not to modify the configuration. The idea is to manually create the directory required to run the program in the development environment. For

Java Heap Overflow:When testing in eclipse, you can set virtual machine parameters in Debug/run, such as -xmx 20M represents the maximum VM heap memory size is 20M,-xms is the smallest heap memory . And then write a dead loop. The class constantly adds objects to the list collection, and when the heap memory exceeds 20
