Error init tomcat in STS

[eladerezador]

Hello i'm new at spring. I'm developing a STS app to learn, i've created a Template Project - Spring MVC Project, i have several controllers, but the problem is that when i try to access to a folder with two different controllers (for example trial1.jsp and another trial2.jsp (@RequestMapping) and both JSP are in the same folder) i get an error message and i have to put the JSP in different folders (then it works) but i need them in the same folder

The error message that is dispayed is the following, occurs when you run the tomcat.

Thanks for your help

[mmartinez]

You have two methods very sameless in order to request mapping:

Ambiguous mapping found. Cannot map 'trampsSameController' bean method

See your RequestMapping annotations ...

[eladerezador]

This I can not do it?

/**
* List all tramps map
*/
@RequestMapping(value = "/populate", method = RequestMethod.GET)
public String listMap(Model model) {
logger.info("Listing Walks in MAP");
model.addAttribute("tramps",trampsService.findMapA ll());
return "populate/list";
}

/**
* List all tramps map same source
*/
@RequestMapping(value = "/populate", method = RequestMethod.GET)
public String listSame(Model model) {
logger.info("Listing Walks in the street");
model.addAttribute("tramps",trampsService.findAll( ));
return "populate/samesource";
}

Thanks

This I can not do it?

You can't do it because this two methods have the same mapping defined.
There is no way to decide which one to invoke when "/populate" URL is called.

Hello,

one more question, then how do I access the same folder with different jsp using RequestMapping?, or I have to do differently?, sorry for my ignorance

Thank you,

[mmartinez]

how do I access the same folder with different jsp using RequestMapping?

You can use same folder with different parameters, different HTTP modes (put, get, post, delete), different subfolders, etc.
Please, visit Spring MVC documentation.

Regards !
