Error during initialisation Portlet Spring 3.0.2 and Tiles 2.1.4

[fabriceMercier]

Hi

I am using Spring Portlet 3.0.2 in Pluto Portal 2.0.1.
It works nice however I want now to include tiles2 support and the portlet initialisation is broken with the error below :

GRAVE: Error creating bean with name 'tilesConfigurer' defined in PortletContext resource [/WEB-INF/bookCatalog-portlet.xml]: Invocation of init method failed; nested exception is java.lang.NullPointerException

My app structure :
/WEB-INF/layout/baseLayout.jsp : Tiles template
/WEB-INF/jsp/home.jsp : JSP include in tiles
/WEB-INF/jsp/tiles.xml : tiles def

I have the tiles.xml definition :

<?xml  version="1.0" encoding="UTF-8" ?>
 
<!DOCTYPE tiles-definitions PUBLIC
      "-//Apache Software Foundation//DTD Tiles Configuration 2.0//EN"
       "http://tiles.apache.org/dtds/tiles-config_2_0.dtd">

<tiles-definitions>

	<definition name="baseLayout" template="/WEB-INF/layout/baseLayout.jsp"/>
	
	<definition name="home" extends="baseLayout">
		<put-attribute name="title" value="Spring3 Portlet Ajax Prototype" type="string" />
		<put-attribute name="content" value="/WEB-INF/jsp/home.jsp" type="template" />
	</definition>
	
	
</tiles-definitions>

I have the bookCatalog-portlet.xml that contains :

	<bean class="org.springframework.web.servlet.view.UrlBasedViewResolver">
		<property name="viewClass" value="org.springframework.web.servlet.view.tiles2.TilesView" />
	</bean>
		
	<bean id="tilesConfigurer" class="org.springframework.web.servlet.view.tiles2.TilesConfigurer">
		<property name="definitions">
		    <list>
		      <value>/WEB-INF/**/tiles.xml</value>
		    </list>
		</property>
	</bean>

Can we help me please ? I can give you any further information to help you debug this case.

Did anyone have any luck with this? We are facing the same issue with Spring DM Server 2.0.2.

Here is my configuration:

<bean id="tilesConfigurer"
    	  class="org.springframework.web.servlet.view.tiles2.TilesConfigurer">
    	<property name="definitions">
    		<list>
    			<value>/WEB-INF/tiles-defs/templates.xml</value>
    		</list>
    	</property>
    </bean>
    
    <bean id="tilesViewResolver"
    	  class="org.springframework.web.servlet.view.UrlBasedViewResolver"
          p:order="2"
    	  p:viewClass="org.springframework.web.servlet.view.tiles2.TilesView" />

and it is failing because at that line as it is trying to get the servletContext.getInitParameterNames(); servletContext is null.

[pdurcek]

We suspect that in our case the problem may be related to the OSGi setup:

<context-param>
		<param-name>contextClass</param-name>
		<param-value>com.springsource.server.web.dm.ServerOsgiBundleXmlWebApplicationContext</param-value>
	</context-param>

Did anyone have luck setting tiles2 up with spring dm server or is able to shine some light on this?

[pdurcek]

We did get little movement on this issue. We moved the spring configs from META-INF/spring/*.xml to WEB-INF/spring/*.xml and that caused the ContextListener to be seen.

However, we still don't have tiles working as we now get an exception that it cannot find a factory to create the application context.

[rajani]

Thanks pdurcek. Moving to WEB=INf/spring/*.xml worked for me.
This is what i did
upgraded my tiles to 2.2.2. This is the exact dependency list I have in my pom.xml (tiles in maven repo is bundle since version 2.0.7 https://issues.apache.org/jira/browse/TILES-282)

       <dependency>
		<groupId>org.apache.tiles</groupId>
		<artifactId>tiles-core</artifactId>
		<version>2.2.2</version>
	</dependency>
	<dependency>
		<groupId>org.apache.tiles</groupId>
		<artifactId>tiles-jsp</artifactId>
		<version>2.2.2</version>
	</dependency>

Then, as suggested by pdurcek moved tiles from META-INF/spring/*.xml to WEB-INF/spring/*.xml
Now seeing this message in log
[2012-07-31 13:05:29.924] INFO start-signalling-1 org.apache.tiles.context.AbstractTilesApplicationC ontextFactory Finished initializing Tiles2 application context.
