Spring Maven project splitted, deployment issues in Eclipse

Question

I've got a Spring maven project separated, myapp.web contains only JSPs and static files, while myapp.core contains app context XMLs and Controllers.

myapp.core

-- src/main/resources/context.xml

-- src/main/resources/mvc-context.xml

myapp.web

-- src/main/webapp/WEB-INF/web.xml

web.xml contains root context configuration and servlet configuration

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath*:/context.xml</param-value>
</context-param>
<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
    ...

<servlet>
    <servlet-name>servlet0</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath*:/mvc-context.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>servlet0</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

I also have OpenSessionInViewFilter configured

<filter>
    <filter-name>hibernateFilter</filter-name>
    <filter-class>
        org.springframework.orm.hibernate3.support.OpenSessionInViewFilter
    </filter-class>
    <init-param>
        <param-name>flushMode</param-name>
        <param-value>AUTO</param-value>
    </init-param>

</filter>
<filter-mapping>
    <filter-name>hibernateFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>  

Now, generating the war from myapp.web and dropping in Tomcat manually works fine. But, when running from Eclipse via "Run On Server", OpenSessionInViewFilter does not see sessionFactory which is configured in context.xml I tried fixing build path of project but it won't run.

org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'sessionFactory' is defined
    at org.springframework.beans.factory.support.DefaultListableBeanFactory.getBeanDefinition(DefaultListableBeanFactory.java:529)
    at org.springframework.beans.factory.support.AbstractBeanFactory.getMergedLocalBeanDefinition(AbstractBeanFactory.java:1094)
    at org.springframework.beans.factory.support.AbstractBeanFactory.doGetBean(AbstractBeanFactory.java:276)
    at org.springframework.beans.factory.support.AbstractBeanFactory.getBean(AbstractBeanFactory.java:196)
    at org.springframework.context.support.AbstractApplicationContext.getBean(AbstractApplicationContext.java:1079)
    at org.springframework.orm.hibernate3.support.OpenSessionInViewFilter.lookupSessionFactory(OpenSessionInViewFilter.java:242)
    at org.springframework.orm.hibernate3.support.OpenSessionInViewFilter.lookupSessionFactory(OpenSessionInViewFilter.java:227)
    at org.springframework.orm.hibernate3.support.OpenSessionInViewFilter.doFilterInternal(OpenSessionInViewFilter.java:171)

Now I know this is a Eclipse/m2e-wtp configuration issue since it's working by manually deploying but I've been unable to fix it. Played with Build Path of project as is usually suggested but no success.

Thanks

Check if the xml files in myapp.core are at the classpath when you run your application via eclipse. Most likely they aren't. You can check by using something like

if (getClass().getResource("my context-xml file") ! = null) {
   System.out.println("No context file on the classpath, won't work");
}

Problem could be that Eclipse is configured no to copy the xml files to the bin directory.

Solved. The problem was this: Context was auto-reloading(not sure why)! myapp.core used to be the entry point(web app). After splitting, it had a missing tick on Project Facets called Utility Project , and Maven Integration for Eclipse was not deploying this project as a jar!
