I'm trying to solve what seems to be a common problem of trying to serve static resources such as images, style sheets and scripts from my Java Web App. I've tried a lot of the solutions offered in other threads but have gotten nowhere, all I get is 404 errors on the resource calls.
The only other thing I can think of is that I'm running on Tomcat 7, but if I try putting 6 on I get a "The server does not support version 3.0 of the J2EE Web module specification." error, so that looks like a no go. Does anyone have any ideas where I might be going wrong?
My project is structured as so:
WebContent
META-INF
Resources
CSS
Images
close.jpg
Scripts
WEB-INF
Lib
Views
index.jsp
Web.xml

Can it be a case-sensitivity issue? Your html says /resources/images but your tree looks like /Resources/Images

I'm new to Spring MVC. I'm trying out simple projects like Hello World.
I originally created a Hello World using IntelliJ IDEA IDE which worked just fine. However, when I tried Eclipse EE IDE, it returned a 404 message

I hope you can help.
Thank you.
I have pulled a Java project from TSF which another colleague created using Eclipse, however, whenever I open the project in IntelliJ it get the following runtime exception:
Exception in thread "main"
org.springframework.beans.factory.BeanDefinitionStoreException:
IOException parsing XML document from class path resource
[spring.xml]; nested exception is java.io.FileNotFoundException: class
path resource [spring.xml] cannot be opened because it does not exist
...
...
I have used Maven to download all the project dependencies which seem to have worked fine as I am not getting any compile time exceptions.
I have uploaded most of the project configuration settings to this imgur album, it should hopefully help.

Any advise and/or suggestion will greatly appreciated. Thanks in advance!
Everything seems ok in your config so I checked using a small project and it appears that the problem may come from the redundant namespaces you are using in your XML headers.
Try modifying the following this:
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.3.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.3.xsd">
To result in something like this:
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">
If that does not work you can also tweak your .iml file by doing the following:
org.jetbrains.idea.maven.project.MavenProjectsManager.isMavenModule="true". You can test quickly by replacing true with false and let IntelliJ reload your project.
I don't know why IntelliJ ignore your spring.xml file, but if you use 2 separate directories for sources and resources, as Maven suggests, your problem should disappear.
You should also create the directory src/main/resources and place your spring.xml file there.
Hope this helps.
Sometimes this can be a problem with the working dir. This blog post explains the problem and how to fix it.
IntelliJ differs from Eclipse in that it sets the working directory to project root which may not be the same as the top level directory of the module you are working on.
This can be fixed in the run configurations by setting the working directory to $MODULE_DIR$.
If this helps maybe set the working directory in Default JUnit run configuration as well as
and fixing all remaining run configurations.
I know there are a lot of explanation about how to configure spring MVC with tomcat and eclipse.
Just wondering what I am missing. I've already check other solutions, but none help me out with this.
Here are the files I'm using:

If you could provide me some feedback in what I'm doing wrong, I'll be thankful.

Go to your server.xml file. You will find your context root there. something like this
<Context docBase="yourApp" path="/yourApp" reloadable="true" source="org.eclipse.jst.jee.server:yourApp"/></Host>
Try loading localhost:8080/yourApp assuming you are running tomcat on port 8080.
At first, the server will search for the index file. So, past your index.jsp file outside the webapp directory.
Also, try adding in your dispatcher-servlet.xml.
First try with local:8080 , If its running fine Then its means your Tomcat is working fine .
Than just put simple .html file just under web-app and right click on it run it as server you can see its run in eclipse ,then you know the actual name your application using for your web application.
Than everything will run smoothly , I had faced this problem myself lots of time
Hi Im trying to follow the tutorial here regarding Struts. I have followed the tutorial exactly but am getting an HTTP 404 error. I know this error basically means that the resource can't be found be the the IDE.
I noticed that the 'Build' folder is actually completely empty - so I'm guessing that it should have automatically created a runnable project based on my project specifics and this is actually where the server looks in order to run an application.
So how do I go about manually generating this file? Should I drag all the resources in? Java classes, JSP files and so? If not how do I configure it to automatically build?
Cheers
EDIT
Have added what I think will be necessary to help solve this:

Looks like a STS bug. You should never see this message otherwise.
