Ok, so I've been stuck trying to setup a Spring MVC project integrated with DOJO for some time now. Finally decided it was time to make an account here and ask the question. I have everything loading except for my dojo.js file that I am referencing from my tag. I'll provide my project hierarchy and what I'm seeing:
My #RequestMapping method.
#RequestMapping(value = "/rbd", method = RequestMethod.GET)
public String home(Locale locale, Model model) {
logger.info("Welcome home! The client locale is {}.", locale);
Date date = new Date();
DateFormat dateFormat = DateFormat.getDateTimeInstance(DateFormat.LONG, DateFormat.LONG, locale);
String formattedDate = dateFormat.format(date);
model.addAttribute("serverTime", formattedDate );
return "home";
}
..When I browse to http://localhost:8080/myproject/rbd the application is successfully loading the home.jsp file, which is shown below:
<%# taglib prefix="spring" uri="http://www.springframework.org/tags" %>
<%# page session="false"%>
<html>
<head>
<meta http-equiv="X-UA-Compatible" content="IE=9; IE=8; IE=7; IE=EDGE" />
<link rel="icon" href="../sba-icon.png" type="image/x-icon" />
<link rel="shortcut icon" href="../sba-icon.png" type="image/x-icon" />
<script src="<spring:url value='/scripts/dojo/dojo.js'/>" data-dojo-config:"locale:'en', async:true, parseOnLoad:false"></script>
..My JBOSS deployments folder follows the hierarchy myproject/scripts/dojo/dojo.js. My home.jsp is in myproject/WEB-INF/views/home.jsp. Is the location of the src tag relative to the location of the home.jsp? I'm so lost because I keep getting 404 errors.. yet I obviously know that dojo.js is on the server. I've tried every path that makes sense to me, I am a Spring/MVC beginner, so don't bash please!
Thanks for the help! :)
EDIT: Here is my init of my DispatcherServlet within my web.xml ...
<servlet>
<servlet-name>rbd</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/spring/rbd/servlet-context.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>rbd</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
..And here is my servlet-context.xml located in the path shown above..
<!-- Handles HTTP GET requests for /resources/** by efficiently serving up static resources in the ${webappRoot}/resources directory -->
<resources mapping="/resources/**" location="/resources/" />
<!-- Resolves views selected for rendering by #Controllers to .jsp resources in the /WEB-INF/views directory -->
<beans:bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<beans:property name="prefix" value="/WEB-INF/views/" />
<beans:property name="suffix" value=".jsp" />
</beans:bean>
The problem is that you have no mapping to your /scripts directory. When using Spring MVC, each request is being mapped to something. You have mapped the following:
/rbd: In your controller
/resources: In your servlet-context.xml (as a resource)
As you can see there's no kind of mapping for the /scripts directory, so in order to make it work you should either move it to the resources-folder (and adjust the links) or provide some additional mapping, by adding the following to your configuration:
<resources mapping="/scripts/**" location="/scripts/" />
Without it Spring simply doesn't know where it should refer to when you're trying to access Dojo.
DispatcherServlet intercepts the js file
you should set <servlet-mapping> like:
<servlet-mapping>
<servlet-name>rbd</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
meanwhile change your controller mapping:
#RequestMapping(value = "/rbd.do", method = RequestMethod.GET)

You must put the mysql-connector jar inside your tomcat's "lib" folder, not in pom.
Why must the JDBC driver be put in TOMCAT_HOME/lib folder?
I am doing project on Spring MVC with html file as viewResolver. Already my project done in ftl (freemarker template) files as viewResolver perfectly. But I want to do conversion of all ftl files into html files. Hence I have tried hard for two days and do some configuration changes in view resolver like below, but nothing worked.
My original code in applicationContext.xml
<bean id="viewResolver"
class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver">
<property name="cache" value="true" />
<property name="prefix" value="/WEB-INF/views/" />

<property name="exposeSessionAttributes" value="true" />
<property name="allowSessionOverride" value="false" />
<property name="exposePathVariables" value="true" />
<property name="requestContextAttribute" value="rc" />
</bean>
I have made some changes like below

class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/views/" />
<property name="suffix" value=".html" />
</bean>

My html files are in "/WEB-INF/views/" folder. What changes I need to do to run the html files. Any alternate way also warmly welcome. Thanks in advance guys...
HTML pages meant for implementing static views, we have great feature in spring to render the static resources like html, css and images i.e.
<mvc:resources mapping="/static/**" location="/WEB-INF/static/" />
Similar question asked here SpringViewResolver for HTML views
================================ SOLUTION ========================================
Newly created Folder structure:
WEB-INF
`-static
|-html
`-index.html
Spring config:

I am using eclipse luna, java 8, tomcat 8 and maven framework.
index.html file is directly under webapp folder and web.xml is under webapp/WEB-INF folder.
If I use index.jsp instead of index.html, it is working. Then welcome page will load using http://172.16.2.16:8080/sampletest/
The issue is only with welcome file. Otherwise spring configuration is working.
http://localhost:8080/sampletest/test/ will load the data from database.

Try adding <mvc:default-servlet-handler/> in your dispatcher-servlet.xml.
See here for details.
You have mapped all your incoming requests to the dispatcher here,
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
So all your URL requests for the application goes inside the dispatcher as '/' maps all incoming requests . check for the stacktraces in your application server log
update:
You get the below warning because there are no handler for the '/' pattern,
WARNING: No mapping found for HTTP request with URI [/AccelFlow/] in
DispatcherServlet with name 'dispatcher'
You can do either of below options ,
Map a url with '/' to the controller
Add a specific URL pattern to the spring dispatcher such as .htm or .do as you wish
Modify your web.xml,
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>*.htm</url-pattern>
</servlet-mapping>
And in your controller,
#RequestMapping(value = "/test.htm", method = RequestMethod.GET)
public #ResponseBody Response display() throws Exception {
accelFlowFacade.disaply();
Response res = new Response();
return res;
}
At the startup by default all incoming requests are mapping to '/' pattern as you write in the web.xml:
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
update:
Try to map a Controller method for the default view:
#RequestMapping(value = "/", method = GET)
public String welcome() {
return "index";
}
Add viewresolver to dispather-servlet.xml:
<bean id="viewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver"
p:prefix="/"
p:suffix=".jsp" />
Remove welcome file from the web.xml as automatically spring will search for index page by default:
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
Welcome file can be access using following changes.
change 1. add resource path in dispatcher as following :
<mvc:resources mapping="/" location="/index.html" />
change 2. add controller handler like following :
#Controller
public class RestController {
#RequestMapping(value = "/", method = RequestMethod.GET)
public String welcome() {
return "index.html";
}
}
changes 3: index.html file should be in WebContent folder in project.
Note : If you are not able to add mvc bean in dispatcher servlet file then add
xmlns:mvc="http://www.springframework.org/schema/mvc
in dispatcher servlet config file.
using <mvc:resources mapping="/" location="/index.html" /> is goods for static pages , however changing it to
#RequestMapping(value = "/", method = RequestMethod.GET)
public String welcome() {
return "index.html";
}
is not good design as all model in other controllers may point back to index page, instead use
<mvc:resources mapping="/" location="/redfresh.html" />
and make refresh page such
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8"/>
<meta http-equiv="refresh" content="0;URL='/index'" />
</head>
<body>
</body>
</html>
and point in controller to index such:
#Controller
public class indexPageController {
#RequestMapping(value = "/index", method = RequestMethod.GET, produces = "text/html")
public String index() {
return "index";
}
}
Just add your index.html to webContent folder. Because welcome file is searched in that folder itself.
Im new to JSF 2. My question is related to BalusC's answer to this question jsf2 ajax update parts based on request parameters I tried the kickstart code BalusC posted and I encountered an EL parsing error:
/nameofpage.xhtml #12,64 rendered="#{bean.panels.contains('u1')}"
Error Parsing: #{bean.panels.contains('u1')}
I guess that this is caused because I'm not running a Servlet 3.0 / EL 2.2 capable container with a /WEB-INF/web.xml declared as per Servlet 3.0 spec. I'm using Tomcat 6.
BalusC suggested in his answer to create a custom EL function. But how do I accomplish this using a custom EL function? Or can this be fixed by just configuring certain parts of my project?
Below is my web.xml:

First create a final class with a public static method which does exactly the job you want:
package com.example;
import java.util.Collection;
public final class Functions {
private Functions() {
// Hide constructor.
}
public static boolean contains(Collection<Object> collection, Object item) {
return collection.contains(item);
}
}
Then define it as a facelet-taglib in /WEB-INF/functions.taglib.xml:

<function-signature>boolean contains(java.util.Collection, java.lang.Object)</function-signature>
</function>
</facelet-taglib>
Then familarize Facelets with the new taglib in the existing /WEB-INF/web.xml:
<context-param>
<param-name>javax.faces.FACELETS_LIBRARIES</param-name>
<param-value>/WEB-INF/functions.taglib.xml</param-value>
</context-param>
(note: if you already have the javax.faces.FACELETS_LIBRARIES definied, then you can just add the new path semicolon separated)
Then define it in the Facelets XHTML file as new XML namespace:
<html
xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:func="http://example.com/functions"
...
>
Finally you can use it as intended:
rendered="#{func:contains(bean.panels, 'u1')}"
As a completely different alternative, you can also include JBoss EL in your project. It works on Tomcat 6.0 and you'll be able to invoke non-getter methods in EL. Drop jboss-el.jar file in /WEB-INF/lib and add the following to your web.xml:
<context-param>
<param-name>com.sun.faces.expressionFactory</param-name>
<param-value>org.jboss.el.ExpressionFactoryImpl</param-value>
</context-param>
Since EL 2.2 there's another approach: create an #ApplicationScoped bean with methods in turn referring to those static functions. See also a.o. Utility methods in application scoped bean.
Does anyone know, or better yet have an example, of a WCF service that will accept a form post encoded multipart/form-data ie. a file upload from a web page?
I have come up empty on google.
Ta, Ant
So, here goes...
Create your service contract which an operation which accepts a stream for its only parameter, decorate with WebInvoke as below
[ServiceContract]
public interface IService1 {
[OperationContract]
[WebInvoke(
Method = "POST",
BodyStyle = WebMessageBodyStyle.Bare,
UriTemplate = "/Upload")]
void Upload(Stream data);
}
Create the class...
public class Service1 : IService1 {
public void Upload(Stream data) {
// Get header info from WebOperationContext.Current.IncomingRequest.Headers
// open and decode the multipart data, save to the desired place
}
And the config, to accept streamed data, and the maximum size
<system.serviceModel>
<bindings>
<webHttpBinding>
<binding name="WebConfiguration"
maxBufferSize="65536"
maxReceivedMessageSize="2000000000"
transferMode="Streamed">
</binding>
</webHttpBinding>
</bindings>
<behaviors>
<endpointBehaviors>
<behavior name="WebBehavior">
<webHttp />
</behavior>
</endpointBehaviors>
<serviceBehaviors>
<behavior name="Sandbox.WCFUpload.Web.Service1Behavior">
<serviceMetadata httpGetEnabled="true" httpGetUrl="" />
<serviceDebug includeExceptionDetailInFaults="false" />
</behavior>
</serviceBehaviors>
</behaviors>
<services>
<service name="Sandbox.WCFUpload.Web.Service1" behaviorConfiguration="Sandbox.WCFUpload.Web.Service1Behavior">
<endpoint
address=""
binding="webHttpBinding"
behaviorConfiguration="WebBehavior"
bindingConfiguration="WebConfiguration"
contract="Sandbox.WCFUpload.Web.IService1" />
</service>
</services>
</system.serviceModel>
Also in the System.Web increase the amount of data allowed in System.Web
<system.web>
<otherStuff>...</otherStuff>
<httpRuntime maxRequestLength="2000000"/>
</system.web>
This is just the basics, but allows for the addition of a Progress method to show an ajax progress bar and you may want to add some security.
I don't exactly know what you're trying to accomplish here, but there's no built-in support in "classic" SOAP-based WCF to capture and handle form post data. You'll have to do that yourself.
On the other hand, if you're talking about REST-based WCF with the webHttpBinding, you could certainly have a service methods that is decorated with the [WebInvoke()] attribute which would be called with a HTTP POST method.
[WebInvoke(Method="POST", UriTemplate="....")]
public string PostHandler(int value)
The URI template would define the URI to use where the HTTP POST should go. You'd have to hook that up to your ASP.NET form (or whatever you're using to actually do the post).
