To fix this issue Invert your string comparisons. Call equals() on the constant value. This will help avoid NullPointerExceptions.
Here is an example: if ("student".equalsIgnoreCase(view))

wish of those help It looks like launcher hasn't been initialized (is null). What is launcher referencing? I would try checking where you begin using launcher and make sure that you are initializing it.

it helps some times After writing an address in etSearch(EDitText) when I clicked the button "btnSearch" it should show the address in map .But it's giving me errors.Can help me , You have to exit the function when addresses is null.
code :
protected void onPostExecute(ArrayList<Address> addresses) {
   if(addresses==null || addresses.size()==0){
       Toast.makeText(getBaseContext(), "No Location found", Toast.LENGTH_SHORT).show();

To fix this issue You have enabled component-scan in mvc-dispatcher-servlet.xml. That causes your UserServiceImpl bean to be registered in two different contexts. The root application context (where it's registered because of the explicit XML configuration), and the web application context (where it's registed via component scanning).
(Check out this to see more on the difference between the two contexts)
code :
<context:component-scan base-package="com.springapp.mvc">
    <context:exclude-filter expression="org.springframework.stereotype.Controller"
<context:component-scan base-package="com.springapp.mvc">
    <context:include-filter expression="org.springframework.stereotype.Controller"
<mvc:resources mapping="/css/**" location="/css/"/>
private UserService userService
public class UserValidator {

   private UserService userService;

    public void validate(Object target, Errors errors) {
      User user = (User) target;
      // confirm that required fields are filled in
      ValidationUtils.rejectIfEmpty(errors, "name", "name.required", "Error msg...");
      ValidationUtils.rejectIfEmpty(errors, "username", "username.required", "Error msg...");
      ValidationUtils.rejectIfEmpty(errors, "password", "password.required", "Error msg...");
      // if the user has filled in a username, check if if already exists
      String username = user.getUsername();
      if (username != null && userService.userExists(username)) { // this calls the userExists() method that causes a NullPointerException
        errors.rejectValue("username", "username.exists", "Error msg...");
private UserValidator userValidator

should help you out This is a bitmap-less field. Problem could be lack of definition for field 2. Also, beware that this field is (I believe) IFB_LLLBINARY not IFB_LLBINARY.
