No i do not, it is just simple file or images or js files

as I mentioned the files are outside sever and located in the file system. It should not work that way

I want to load html , js, css files from file system while running tomcat 7. Tried the following approach, and none of it works.
1) put <Context docBase="D:\temp\uploads\myfile" path="/MySharedHTML"/> under conf/server.xml

2) created folder conf\Catalina\localhost and put ROOT.xml under it with following content
<?xml version='1.0' encoding='utf-8'?>
<Context docBase="D:\temp\uploads\myfile" path="/MySharedHTML"/>

when i tried to test my code with the following jsp file with tomcat running, nothing showed up

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<html>
<head>
<title>Tag Example</title>
</head>
<body>da
<c:import url="/MySharedHTML/extraweb.html"/>
</body>
</html>
Please help!

Thank you

@RequestMapping(value = "/save", method = RequestMethod.POST)
@PreAuthorize("hasRole('PERMISSION_SAVEORADD')")
public ModelAndView savePermission(@ModelAttribute Permission permission, BindingResult result)
throws PermissionNotFoundException {
System.out.println(permission.getPermRoles().size());

permissionDao.updatePermission(permission);
return new ModelAndView("redirect:/admin/role/permission/list");
}
The above is my controller

Here is my code:

@Configuration
@ComponentScan(basePackages = "com.webapp")
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {

@Bean
@Override
public AuthenticationManager authenticationManagerBean() throws Exception {
return super.authenticationManagerBean();
}

@Override
protected void configure(HttpSecurity http) throws Exception {
http.
authorizeRequests().antMatchers("/resources/**").permitAll().
antMatchers("/admin/**").hasRole("ADMIN").
anyRequest().authenticated().
and().
formLogin().loginPage("/login").permitAll().
and().
logout().permitAll();
}

@Autowired
public void configureGlobal(UserDetailsService userDetailsService, AuthenticationManagerBuilder auth)
throws Exception {

auth.userDetailsService(userDetailsService);

}
}
when a request /admin/* comes in, it will verify if the user has admin role by calling "antMatchers("/admin/**").hasRole("ADMIN")." , but in my controller, it does not check if the user has other permissions with @PreAuthorize .

@Controller
@SessionAttributes({ "user" })
@RequestMapping(value = "/admin/user")
@PreAuthorize("denyAll")
public class UserController {

static Logger logger = LoggerFactory.getLogger(UserController.class);

@Autowired
private RoleDAO roleDao;

@Autowired
private MessageSource messageSource;

@Autowired
private UserDAO userDao;

@RequestMapping(value = { "/", "/list" }, method = RequestMethod.GET)
@PreAuthorize("hasRole('USER_VIEW')")
public ModelAndView listUsers() {

List<User> users = userDao.list();
ModelAndView model = new ModelAndView("/admin/user/user-list");
model.addObject("users", users);
if (model.getModel().get("user") == null) {
model.getModel().put("user", new User());
}
this.loadRoles(model);
return model;
}
}

SEVERE: PWC6117: File "/home/tyang/netbeanPorject/Admin/AdminWeb/target/AdminWeb-1.1.29-SNAPSHOT/error/error.jsp" not found
if i use index as the key, then the dupicated exception should never be thrown.

there is no any combination of the fields can be the key , since they all could be dupciated.

so i assume that no key in the record. and no dupicated exception should be thrown
the following is my owner field description:

The id value (an 8 digit number) of the customer who has booked this. Note that for this application, you should assume that customers and CSRs know their customer ids. The system you are writing does not interact with these numbers, rather it simply records them. If this field is all blanks, the record is available for sale.


does the above mean i should not consider of using owner field as the key ?

thank you in advance
i have exactly the same fields as yours, so i guess i do not need to worry about exception.

thank you for you help
"Well, the record number is not exactly a field of a record, it is just the position the records appear in the database. So, it'll never repeat. But your thought was correct, a field that repeats cannot be primary key."

so how can i decide which combination of my field is the key?
since all fields could be repeated except owner.
but ont he description, it says we do not interact with the owner id.
so we can not make it as primary key.
"the record number (which is the physical position of the record in the database), and since 2 records cannot be in the same entry in the database file, I never throw a DuplicateKeyException."

record number must be different in the data base, but the field in each record could be exactly the same , in this case, i guess it is not correct to use recored number as key

am i right?
/** Creates a new record in the database (possibly reusing a
* deleted entry). Inserts the given data, and returns the record
* number of the new record.
* @param data the new record to insert into the database
* @return the index of the new record in the database
* @throws DuplicateKeyException indicates the record already exists.
*/
public long createRecord(String [] data)throws DuplicateKeyException{
return 1L ;
}

when should i consider a input record to be Duplicate?

thank you in advance
