Hi,
I have MyEclipse for Spring 8.6. I download the MVC showcase example from the springsource samples repository. This does not build – In the servlet context.xml there is a line
<!– Handles HTTP GET requests for /resources/** by efficiently serving up static resources in the ${webappRoot}/resources/ directory –>
<resources mapping=”/resources/**” location=”/resources/” />which is giving the error

cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element ‘resources’. servlet-context.xml /mvc-showcase/src/main/webapp/WEB-INF/spring/appServlet line 16 XML Problem

On googling this I found that it is suggested that we should use mvc:resources and include the corresponding declarations which I did

<beans:beans xmlns=”http://www.springframework.org/schema/mvc&#8221;
xmlns:xsi=”http://www.w3.org/2001/XMLSchema-instance&#8221;
xmlns:beans=”http://www.springframework.org/schema/beans&#8221;
xmlns:mvc=”http://www.springframework.org/schema/mvc&#8221;
xsi:schemaLocation=”
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd”&gt;

and changed the line concerned to
<mvc:resources mapping=”/resources/**” location=”/resources/” />

but I still get the error

Description Resource Path Location Type
cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element ‘mvc:resources’. servlet-context.xml /mvc-showcase/src/main/webapp/WEB-INF/spring/appServlet line 16 XML Problem

How do I get rid of this error.
If it needs a spring update how do I do that ?, From the workscenter I see that there are no updates available.

Thanks

Hi,
Related to my previous post I found this at the springsource blog – http://blog.springsource.com/2009/12/21/mvc-simplifications-in-spring-3-0/ namely –

“the next line hightlights a new feature added in version 3.0.4:

view sourceprint?
1 <!– Handles GET requests for /resources/** by efficiently serving static content in the ${webappRoot}/resources dir –>

2 <mvc:resources mapping=”/resources/**” location=”/resources/” />
The mvc:resources tag lets you configure a handler for static resources, such as css and javascript files. In this case, requests for /resources/** are mapped to files inside the /resources directory.
”
So it looks like this needs Spring webmvc 3.0.4. How do I update MyEclipse with this version – nothing comes up in the Software Configuration Center

I just grabbed this project from the spring samples repo. It compiles and runs just fine for me. I wonder if they updated the project recently?

If you are still having problems with the project, you can easily update the spring version that is used. Since this project is a maven project, it uses whatever version of the spring framework you tell it to use. Simply open the /mvc-showcase/pom.xml. you will see a bunch of entries in the pom that determine the spring libraries to be used. for example:

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>${org.springframework-version}</version>
</dependency>

This is actually a handy maven feature, it enables you to set a single property that sets the Spring version and that is then used by all of hte spring component. At the top of the file look for this:

<properties>
<java-version>1.6</java-version>
<org.springframework-version>3.0.5.RELEASE</org.springframework-version>
<org.springframework.roo-version>1.1.0.RELEASE</org.springframework.roo-version>
<org.aspectj-version>1.6.9</org.aspectj-version>
<org.slf4j-version>1.6.1</org.slf4j-version>
</properties>

In the version I just pulled from the repo, you can see that this one is setting the “org.springframework-version” property to “3.0.5.RELEASE” If you want to change it, for instance to an older version that is 3.0.4, simply change the property. It will now look like:

<org.springframework-version>3.0.4.RELEASE</org.springframework-version>

And that is all you have to do in Maven projects to change the version of Spring in use. The projects created by ME4S are quite similar. Here is the same snippet created as part of an ME4S project.

<properties>
<org.springframework.webflow.version>2.0.7.RELEASE</org.springframework.webflow.version>
<org.springframework.version>3.0.5.RELEASE</org.springframework.version>
<org.springframework.security.version>3.0.0.RELEASE</org.springframework.security.version>
</properties>

Maven makes this all really easy to do. Let me know if you have any other questions.

The mvc-showcase project is a Maven project, and dependencies should be resolved using Maven. According to the springsource blog you reference, the validation error shouldn’t cause any problems running the project. Can you confirm?

Hi,

Thanks for your replies.

Firstly – I downloaded the mvc showcase sample again and this time the pom referred to 3.0.5 as mentioned but that did not remove the validation error.
Secondly – I checked that at least the JUnit test for the SimpleController runs even with validation error.
But I was finally able to get rid of the validation errors as follows

Found that the problem was because the spring mvc 3.0 xsd which came wth the my eclipse installation is old and does not have the resources element. So downloaded the xsd from the location at springsource http://www.springframework.org/schema/mvc.
Then manually replaced my local xsds with the downloaded copies which had the resources element – this finally resolved the error.

What I am wondering now is there any way to get these xsds updated other than manually replacing them.

The local xsds can be found at MyEclipse for Spring 8.6\configuration\org.eclipse.osgi\bundles\91\1\.cp\catalog-xsd and MyEclipse for Spring 8.6\configuration\org.eclipse.osgi\bundles\1153\1\.cp\org\springframework\web\servlet\config

Unfortunately, this is a manual process for now. We are updated the schemas in 9.0, so the error will go away when you upgrade. It is strange though, I did not manually upgrade my schema and I did not see the validation error. I will see if I can figure out why that is the case.

I have followed the stpes to try to remove the error around <mvc:resources …>. Replaced the file spring-mvc-3.0.xsd by the new one including the new annotations but something strange is happening:

Only found one instance of the file under

MyEclipse for Spring 8.6\configuration\org.eclipse.osgi\bundles\ 1176\ 1\ .cp\ org\springframework\web\servlet\config

(Sorry for the spaces)

As soon as I start MyEclipse 8.6.1 I open de file and inmediatly add the tag <mvc:resources (Ctrl+Tab detects it). Less than a minute later the error appears again, and even if I check again (Ctrl+Tab) looking for the <mvc: resources…> the tag does not appear any more.

I’m sure I’m missing something, the key detail… any idea?

Thanks in advance

PD: The project compiles and works fine anyway, just want to fix the xsd point.

I thought I would document my success.

I was able to make this work using a similar method described in this thread. You can locate the xsd that is in use by looking in MyEclipse->Files and Editors->XML Catalog

In the XML catalogs entry click on “http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd&#8221;

In the details window at the bottom, the Location field will tell you where the xsd is being loaded from. Replace that xsd with the 3.0.5 xsd and restart Eclipse. I cleared MyEclipse->Internet Tools->Cache before restarting.

Good luck.

Restarting only MyEclipse the error continued there but it worked after restarting computer. I don’t understand but it’s working now, thanks!

Hello everyone,

I’m currently using 9.0 M2 and I noticed the included Spring libraries are still outdated (3.0.1) vs current release 3.0.5.

Are you going to update them before GA?
I assume this would solve the issue regarding the new mvc:resources tag.

Also: please update Hibernate from 3.3 to 3.6.1 while you are at it. 😉

Thank you very much.

They will be updated for GA.
