Which will be thrown by the JVM and platform API methods), including IllegalArgumentException There are various standard unechecked exceptions that you can use for common conditions (and.A method must declare which checked exceptions (if any) it throws, but does not have.Exceptions can be checked or unchecked, depending.If there is no catch block that can catch the method, then it will eventually be passed to.If an exception is thrown back from a method, then that method does not return a value as normal.When an exception is thrown, normal program flow stops and control is passed back to the nearest suitable.At any point where an error condition is detected, you may throw an exception.Here is the trace : Could not instantiate bean class : Constructor threw exception nested exception is : javax/servlet/ServletContextĪt .instantiateClass(BeanUtils.java:163)Īt .instantiateClass(BeanUtils.java:105)Īt .instantiateClass(BeanUtils.java:130)Īt .ContextLoaderUtils.resolveContextLoader(ContextLoaderUtils.java:118)Īt .ContextLoaderUtils.buildMergedContextConfiguration(ContextLoaderUtils.java:594)Īt .ContextLoaderUtils.buildMergedContextConfiguration(ContextLoaderUtils.java:560)Īt .TestContext.(TestContext.java:99)Īt .TestContextManager.(TestContextManager.java:117)Īt .(SpringJUnit4ClassRunner.java:119)Īt .junit4.SpringJUnit4ClassRunner.(SpringJUnit4ClassRunner.java:108)Īt 0(Native Method)Īt (NativeConstructorAccessorImpl.java:57)Īt (DelegatingConstructorAccessorImpl.java:45)Īt .newInstance(Constructor.java:526)Īt .AnnotatedBuilder.buildRunner(AnnotatedBuilder.java:31)Īt .nnerForClass(AnnotatedBuilder.java:24)Īt .RunnerBuilder.safeRunnerForClass(RunnerBuilder.java:57)Īt .nnerForClass(AllDefaultPossibilitiesBuilder.java:29)Īt .ClassRequest.getRunner(ClassRequest.java:24)Īt .(JUnitStarter.java:63)Ĭaused by: : javax/servlet/ServletContextĪt .web.WebDelegatingSmartContextLoader.(WebDelegatingSmartContextLoader.java:36)Īt .instantiateClass(BeanUtils.java:148)Ĭaused by: : Īt $1.run(URLClassLoader.java:366)Īt $1.run(URLClassLoader.java:355)Īt (Native Method)Īt (URLClassLoader.java:354)Īt (ClassLoader.java:424)Īt $AppClassLoader.loadClass(Launcher.java:308)Īt (ClassLoader.Exceptions are used to control error flow in a Java program. I added the following to pom.xml but didn't work. I am trying to setup the Junit test with the MockMVC.įrom this link - 'either must not use the Servlet API or you need to provide it on the classpath'. There must be something similar for Maven as well.Īlso you need rvlet-api only during compile time as the container you are using to run the server will provide the actual APIs at runtime. I generally use Ivy and in Eclipse I do Project -> Properties ->Deployment Assembly -> Add -> java Build Path Enteries -> Ivy -> Finish You need to add the corresponding jar so that it can be found at runtime.

Solution 2Ĭlass is not found at runtime but is available at compile time. It should solve your NoClassDefFoundError problem. In my projects I use glassfish even if I later use tomcat as a servlet container, but I once found the dependency googling for the same problem : You have to add a dependency that bring the implementation of all Java EE classes in test scope. Anyway, you declare it as 'provided' which says to maven 'don't worry, I know it will be on classpath'.

The dependency you added to your pom is only the API : it declares everything but contains no implementation. But during the tests you need a jar to provide them. As Aniket Thakur said, the container will provide all Java servlet classes at runtime.
