IOException parsing XML document from class path resource - HTTP Status 500 - Servlet.init()

Question

I am building a simple Spring MVC Maven built java WAR application. My Maven project cleans and builds successfully and deploys to the server with no errors using the eclipse tomcat plugin. However, when I try to run the application Servlet, I get the following exception :

    Aug 23, 2013 2:35:29 PM org.springframework.web.servlet.FrameworkServlet initServletBean

I am new to using this system so I'm not sure where I have gone wrong, can anyone help me solve this error?

do you have spring/file-watcher.xml in WEB-INF/classes ? — sanbhat

Hi, I don't have a WEB-INF/classes folder, should I create one? EDIT : Scratch that, I've checked the target directory, and theres a WEB-INF/classes directory there that contains a file-watcher.xml file. Does it need to be in a spring directory? — MattTheHack
– MattTheHack, Commented Aug 23, 2013 at 13:48
Your path should be matched to your context param in web.xml file <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/file-watcher.xml</param-value> — Prabhakaran Ramaswamy

Thanks, I've done this but I still have the error...Any other ideas? — MattTheHack

Create the spring named folder under WEB-INF.

Create the file-watcher.xml file inside the spring folder.

After that your path will be

yourproject\src\main\webapp\WEB-INF\spring\file-watcher.xml

Paste the below XML content to file-watcher.xml

  <?xml version="1.0" encoding="UTF-8"?>
   <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"
       default-autowire="byName">

     <bean id="FileWatcher" class="com.test.FileWatcher" init-method="initialize" />

   </beans>

Then run your server. It will work.

Hi there, Thanks for the help. I'm still getting the Error code 500. Any idea why the spring folder isn't generated automatically? I have to keep adding it to the target/WEB-INF directory after every maven clean install

Prabhakaran Ramaswamy Over a year ago

Please place like this user-management\src\main\webapp\WEB-INF\spring\file-watcher.xml. user-management is my project root path. Don't place any resources with in target folder that will destroyed if you run mvn clean.

MattTheHack Over a year ago

That works fine, but still an error code 500. The folder ends up here : ...\FileSystem\target\watchFileSystem-0.0.1-SNAPSHOT\WEB-INF\spring

Prabhakaran Ramaswamy Over a year ago

Thats okay maven will copy the resources and other stuff to target folder. Are you getting any exception. if yes post here

Prabhakaran Ramaswamy Over a year ago

Its path problem I am sure about it. see the IOException and nested exception is FileNotFoundException ....... IOException parsing XML document from class path resource [spring/file-watcher.xml]; nested exception is java.io.FileNotFoundException: class path resource [spring/file-watcher.xml] cannot be opened because it does not exist at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.loadBeanDefinitions(XmlBeanDefinitionReader.java:341)

One suggestion i might give you is for you check the location of your file-watcher.xml

If you are using Maven you might want to consider putting your file-watcher.xml inside the resources folder.

And in your web.xml file kindly declare your tag as shown below:

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:file-watcher.xml</param-value>
    </context-param>

NB: Make sure that src/main/java/resources is on your classpath and bear in mind that in Maven, the standard directory for resources is src/main/resources, so I suggest you put this file there.
