    java.lang.NullPointerException
    at org.apache.jsp.Mine_jsp._jspInit(Mine_jsp.java:22)

    A NPE on _jspInit() is typical whenever the /WEB-INF/lib folder of the webapp is littered with servletcontainer-specific libraries such as jsp-api.jar, j2ee.jar, etcetera. This is a major mistake, those libraries belong in the servletcontainer side. Cleanup your /WEB-INF/lib folder to remove them all. If you put them there to overcome compilation errors, you should have solved it differently. See also How do I import the javax.servlet API in my Eclipse project?
