so how should I fix this ? please help!

[Daniel Demesmaecker]

I dont know if it will work, I don't use xml configuration to often (I always use springboot), but try to do the requestmapping above your controller:

@Controller
@RequestMapping("/")
public class HomeController {
    @GetMapping
    public String handleGetHome(){
       return "homepage";
    }
 }

Or if it's the only method for that url you could just move your line 8 as a whole and skip the @GetMapping

[Aziz Rupawala]

I tried as you said above but it still won't work.

[Daniel Demesmaecker]

I'll flag your post for some extra attention, but you'll have to wait till  someone else comes a long.
I don't really see anything wrong, but as I said I'm not to experiienced with xml configurations.
It might take a couple of hours, for most of the users it's not even 8am, but you'll surely get the help you need

[Daniel Demesmaecker]

Could you post your stacktrace, since what you posted isn't your error, but your server starting up

[Aziz Rupawala]

Actually I'm not getting any error i'm getting following warning

19:54:56,445 WARN  [org.springframework.web.servlet.PageNotFound] (default task-1) No mapping for GET /ProjectFE/

 after running the application i.e.  Also Thankyou very much for you assistance.

[Aziz Rupawala]

Also here's the structure of my project :

[Daniel Demesmaecker]

Warnings dont make your app fail. So you just get a 404?

[Aziz Rupawala]

Daniel Demesmaecker wrote:Warnings dont make your app fail. So you just get a 404?

yes that's what I got. there are no errors in the project.

[Daniel Demesmaecker]

Did you copy that config or write it yourself? Of seems weird to me not to put your jsp's in your WEB-INF, but you configurated it that way., zo it shouldnt be a prob. In springboot you have to put your config, so your application.properties, in your resources root, following that logica, I would move your config files.
I think, but once again i dont use XML, this line means the same

sources mapping="/resources/**" location="/resources/" />

.
But maybe I should stop confussing you, since I dont really know and just wait till someone more familiar with XML config comes a long

If there are a lot of typo's, Im on my phone and have Dutch autocorrect on. I dont always notice when he changes something

well talking about if  I copied the config file then yes, but I have done the required changes but I guess I've missed something in the config file, hence the code ain't working.

[Daniel Demesmaecker]

How fixed are you on using spring? Of you would switch to springBoot you wouldnt have tis prob

[Aziz Rupawala]

well I recently got started with spring and I don't know anything about spring boot frankly speaking.

[Daniel Demesmaecker]

The principale is the same. The big difference is that spring takes care of a lot of the config. What kind of build tool do you use?

[Aziz Rupawala]

I've been using Maven.

[Daniel Demesmaecker]

If you want to the springBoot. I could post what you have to change to make it work with your current project.

[Aziz Rupawala]

Alright, you can post that I'll try the code if no one posts a reply. Also if possible please tell me what changes I'll have to make.

[Daniel Demesmaecker]

You have to adjust you pom a bit, add a application.properties  and annotate your MainClass, that's about it. Could you post your pom

[Daniel Demesmaecker]

Add this to the top of your pom.xml:

 <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.9.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
        <java.version>1.8</java.version>
    </properties>

Deppending on your project you will need to add aditional dependencies.
Your application.properties you put in you resource root and should look something like this:

# CLIENT
spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp
server.port=8080
# MEDIA
spring.http.multipart.max-file-size=1MB
spring.http.multipart.max-request-size=1MB

If you use a db, tell me cause then you have to make aditional changes. Keep in mind that based on this, you would put your jsp's in webapp/WEB-INF/jsp
Finally annotate your MainClass with:

@SpringBootApplication
@ComponentScan(basepackage = "yourBasepackage")//optional

[Daniel Demesmaecker]

If you rather use Spring, be a bit more patient, there are a lot of "oldtimers" here on the site that surely can help you with your configuration

[Aziz Rupawala]

Alright Thankyou very much I'll try this out If I have any problems I'll ask.

[Aziz Rupawala]

Daniel Demesmaecker wrote:If you rather use Spring, be a bit more patient, there are a lot of "oldtimers" here on the site that surely can help you with your configuration

Well yeah I've been waiting but nobody is replying. I'll have to wait a bit more it seems.

[Daniel Demesmaecker]

Most users are in the us, there it's only 9hr30, depending on the timezone of course , I know of two mods that are from the uk, but there it's also only 16hr30 so they're most likely still at work

[Daniel Demesmaecker]

Were you able to get it working?

[Aziz Rupawala]

Nope couldn't fix the issue.

[Daniel Demesmaecker]

Could you post your project on github or something. Then I could take a look and make it work my zelf. Since weird but true, but no one else responded

[Daniel Demesmaecker]

Or I could report your post. Normally that's a bad thing, but at least then a mod will notice

[Tim Moores]

Daniel Demesmaecker wrote:Or I could report your post. Normally that's a bad thing, but at least then a mod will notice

Indeed, this is not what the reporting feature is for.

[Aziz Rupawala]

ok so now the issue has been resolved it was a silly mistake, I had to do a small edit in the spring-config.xml file i.e I had to change

views

to  

Views

and that's it.

[Daniel Demesmaecker]

Lol... I would have changed Views to views, according to convention packagenames start with small letters
