Can't change contextConfigLocation

**blaise17** · Jan 30th, 2009, 04:11 AM

Hi,
I'm trying to change the location of the applicationContext.xml file, or even the name of it, and pointing to it from the web.xml using contextConfigLocation, but I keep getting the same error: It first tries to read beans for the web application from the file I point to (/WEB-INF/context/applicationContext.xml) and then for each portlet it tries to read from the portlet's own context (eg /WEB-INF/basic-portlet.xml) and also the default location (/WEB-INF/applicationContext.xml)... which it obviously can't find as it's not there... which gives me a FileNotFoundException and portlet death... what I can't figure out is why it's looking there when it has clearly read the web.xml that points to a different location... thoughts?

When posting code/xml/stacktraces please use [ code][/code ] tags...

I suggest you read the web chapter and what the FrameworkPortlet actually does and how everything works together.

Setting the context param 'contextConfigLocation' will only set the location used by the ContextLoaderListener, it is ignored by everything else. Each Servlet/Portlet loads its own configuration and by default it looks for something which is named [portletname]-portlet.xml or the default (applicationContext.xml). If you want to override this set the contextConfigLocation for each portlet/servlet (as an init-param to those).

**blaise17** · Jan 30th, 2009, 07:51 AM

Okay, I'll post it in code tags in future, I just didn't as it clearly isn't code.

"Each Servlet/Portlet loads its own configuration and by default it looks for something which is named [portletname]-portlet.xml or the default (applicationContext.xml)."

But the portlet's configuration IS IN [portletname]-portlet.xml... nothing I've read (and I have read that chapter) says that it should look in BOTH if it finds the bean in the first.

Additionally, in that chapter it says it will look in the portlet's default context or the root application context, which in this case is the one that has been changed...

Does this mean that if I want to change the root application context I have to then set contextConfigLocation in EVERY portlet to be their own default and the changed location of the root one? In which case what is the point of setting it in the web.xml?

**Marten Deinum** · Jan 30th, 2009, 04:48 PM

Additionally, in that chapter it says it will look in the portlet's default context or the root application context, which in this case is the one that has been changed...

It looks for BEANS in the root context it doesn't look at the context-param named contextConfigLocation.

The root one is loaded by the ContextLoaderListener, all the Portlets/Servlets automatically detect this ApplicationContext and use that as the parent ApplicationContext for the ApplicationContext created by the Portlet.

**blaise17** · Feb 2nd, 2009, 04:07 AM

That is exactly what I'm asking about!

The root one being loaded for everything is the one that has the changed location, which it is reading...
But then, it also tries reading a root one in the default location for the root one, which isn't there because I've specified the root one to be moved...

The only bean in the root context is a view resolver... the other beans for each portlet are in their own [portlet-name]-portlet.xml files... what exactly are you trying to say? That I've put the contextConfigLocation param in there? Because I haven't... that's not where it goes...

I've specified it in the web.xml... but you can specify the portlet one's individuallly in the portlet.xml... which is what I was asking if that was what I had to do since it's ignoring that the one specified in the web.xml is the root for the portlets...

**Marten Deinum** · Feb 2nd, 2009, 04:19 AM

I'm probably stupid but you now totally lost me. Please post your configuration (web.xml/portlet.xml)...

This is my web.xml:

I can post my portlet.xml as well if you like, but I'm not currently setting anything special in there... do you want me to?

**Marten Deinum** · Feb 2nd, 2009, 04:43 AM

Please do and the exact version of spring you are using could be helpful also.

**Marten Deinum** · Feb 2nd, 2009, 05:04 AM

Well you tell the portlet to load Spring-portlet.xml AND /WEB-INF/applicationContext.xml. Which isn't there so it doesn't load. Also WHY should it load the /WEB-INF/applicationContext.xml (which probably should be /WEB-INF/context/applicationContext).

If you only have a Spring-portlet.xml to load you can remove the init-param. It will automatically detect the ApplicationContext loaded by the ContextLoaderListener...

Code:

<portlet>
    <description>A Spring Portlet</description>
    <portlet-name>Spring</portlet-name>
    <display-name>Spring Portlet</display-name>
    <portlet-class>org.springframework.web.portlet.DispatcherPortlet</portlet-class>
    <init-param>
        <name>contextConfigLocation</name>
        <value>/WEB-INF/Spring-portlet.xml,/WEB-INF/applicationContext.xml</value>
    </init-param>
    <expiration-cache>0</expiration-cache>
    <supports>
        <mime-type>text/html</mime-type>
        <portlet-mode>VIEW</portlet-mode>
        <portlet-mode>HELP</portlet-mode>
        <portlet-mode>EDIT</portlet-mode>
    </supports>
    <portlet-info>
        <title>Spring Portlet</title>
        <short-title>Spring</short-title>
    </portlet-info>
</portlet>

You don't need (or even must not) let the portlet load the root application context, because it will detect the one already present. The sequence when you start the server..

1. ContextLoaderListener detects the contextConfigLocations context parameter and uses that value to load an ApplicationContext (ROOT-CONTEXT)
2. Portlet named 'Basic' is loaded
3. Portlet named 'Spring' is loaded, it sees the contextConfigLocations init parameters and uses that value to load an ApplicationContext, before it starts loading it sees if there already is an ApplicationContext loaded by a ContextLoaderListener if so it uses that as a parent.
4. Portlet named 'BasicSpring' is loaded (see 3)
5. Portlet named 'helloworld' is loaded, it doesn't have a contextConfigLocations init parameter so it is going to only load the helloworld-portlet.xml and see if an ApplicationContext is already loaded by the ContextLoaderListener (and use that as a parent).

Which in the end results in 4 ApplicationContexts, 1 Root, 3 Portlet contexts all pointing to the root one.
