Constant warning when running tomcat from intellij

All of a sudden, when i run tomcat from within intellij, the output console is constantly bombarded with messages.
(very) short video showing this:
http://screencast.com/t/ddBhIh3UZiA
The messages constantly output is:
16:05:31,157 WARN http-nio-8222-exec-1 servlet.PageNotFound:198 - Request method 'HEAD' not supported
16:05:31,158 WARN http-nio-8222-exec-2 servlet.PageNotFound:1120 - No mapping found for HTTP request with URI [/] in DispatcherServlet with name 'dispatcher'
I am using Spring 4.1 and tomcat 8.
Java 8 and Windows 8.1
This phenomenon didnt use to happen before and it suddently started occuring. What is going on?

I'm having the exact same problem. If you have your Tomcat run configuration set to open a browser on launch, IntelliJ will try to ping the website to ensure it's up prior to opening the browser. I believe it's doing HEAD requests and since your site isn't set to answer / HEAD requests, you get the error.
Unchecking the "After launch" checkbox under "Open browser" in the server tab of the run configuration fixed it for me.
As for getting JetBrains to fix this, I'm not sure what to do about it. I did just upgrade to 14.0.3 so that might be the cause...

Solved by JetBrains in this ticket, and if you want you can change a Jar to avoid the regression.

It seems your client is using HEAD has the request method. It is similar to GET but it says to the server that it must not return message-body in the response.
Either check your pages or client for HEAD requests or accept HEAD as RequestMethod like this:
#RequestMapping(method = {RequestMethod.GET, RequestMethod.HEAD})

blueimp jQuery-File-Upload redirect

I've been through a similar issue when using the plugin on Google App Engine. Here is the complete working code. May be you'll have slight differences, but I guess you'll find how a Java server have to be done for this plugin to work.

Post to a servlet from AJAX code Syntax issues

I am sending some data from AJAX to a servlet. This syntax works very well on my local.
xmlhttp.open("GET", "../MyTestServlet?section="+sId, true);
However, on our DEV UNIX server this does not work. I tried the following, but this does not work
xmlhttp.open("GET", "<%=request.getContextPath()%>/MyTestServlet?section=+sId", true);
The servlets are in the following package "com.myPackage.myApp.servlets"
What would be the right syntax?

Try using real path on the server system
ServletContext.getRealPath()

Well, the issue was not so much the path of the servlet, but a different one. Actually the Query.properties file also had path issues and once I solved it, it started to work. So actually the first link worked. Sorry folks for wasting your time on this one. Thanks for all the responses.

Mochahost GWT rpc and Servlet not working

While deploying my app to mochahost, I met the problem between servlet and GWT-RPC communicate. The error shows:
HTTP Status 404 - /403.shtml
type Status report
message /403.shtml
description The requested resource (/403.shtml) is not available.
.war file works perfectly on my workstation, but not working on mochahost.
Any ideas to solve it?
Thanks in advance.

Mochahost have a very good support, try livechatting with their tech department, you will probably have the thing solved.
That's what I do.

Make sure you update live site URL. For instance, generally, on local system you access web app as http://localhost:8080/myapp but, on server it changes to http://[www.]myapp.com. Again, this is just an instance. The point is, the live site must reflect correct URL from code (servlet/JSP/action/etc...) and configuration properties, if any.
Comment 'DirectoryIndex' property in .htaccess file if you do not have any index file.
Comment 'RewriteCond' property in .htaccess file if you do not have any rewrite requirement.
For sure, one of the reason - if client does not accept cookies and servlet does not encode URL.

Request for a non existent page results in blank page in Spring web application

Am using a Spring web application.
Have used an ExceptionHandler for trapping all the exceptions in my application.
However, when an error occurs such as 404, the default tomcat server error message was getting displayed.
So I added the below code
<error-page>
<error-code>404</error-code>
<location>/errorPage.html</location>
</error-page>
in my web.xml.
Now when I try to access a non-existing page, am getting a blank page in Firefox. When debugging with Firebug, I noticed only response headers are getting passed back and no response content is visible.
In IE, it is displaying browser's default 404 page.
What am I missing here?

The 404 error code is configured properly, but it will caused the “.htm” extension handling conflict between the “servlet container” and Spring’s “DispatcherServlet“. To solve it, try change the 404.htm to other file extension, for example 404.jsp.

Interestingly, when I changed my errorPage.html to errorPage.jsp it worked fine. I left the other configuration unchanged and only changed this. Still dont know why this was happening. Will try to find out during the weekend.
Thanks for the responses.
