Getting QuercusView to work with SpringMVC

Question

I'm trying to implement SpringMVC + Quercus as described at http://blog.caucho.com/2009/04/14/using-php-as-a-spring-mvc-view-via-quercus/ .

So I setup Spring like this:

web.xml

<servlet>
        <servlet-name>Quercus Servlet</servlet-name>
        <servlet-class>com.caucho.quercus.servlet.QuercusServlet</servlet-class>
        <init-param>
            <param-name>ini-file</param-name>
            <param-value>WEB-INF/php.ini</param-value>
        </init-param>
    </servlet>

<servlet-mapping>
        <servlet-name>Quercus Servlet</servlet-name>
        <url-pattern>*.php</url-pattern>
    </servlet-mapping>

dispatcher-servlet.xml

<bean id="viewResolver"
          class="org.springframework.web.servlet.view.InternalResourceViewResolver"
          p:prefix="/WEB-INF/themes/eyitope/"
          p:suffix=".jsp"/>

<bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">
        <property name="order" value="1" />
        <property name="ignoreAcceptHeader" value="true" />
        <property name="mediaTypes">
            <map>
                <entry key="php" value="application/php" />
            </map>
        </property>
        <property name="viewResolvers">
            <list> 
                <!-- used to handle all files with .php extension -->
                <bean class="org.springframework.web.servlet.view.UrlBasedViewResolver">
                    <property name="viewClass" value="com.caucho.spring.quercus.QuercusView"/>
                    <property name="order" value="1"/>
                    <property name="prefix" value="/WEB-INF/themes/php/"/>
                    <property name="suffix" value=".php"/>
                </bean>
            </list>
        </property>

        <!-- If a compatible view cannot be supplied by the
            ViewResolver chain, then the list of views specified through the DefaultViews property will be
            consulted.
        -->
        <property name="defaultViews">
            <list>
                <bean class="org.springframework.web.servlet.view.json.MappingJacksonJsonView" />
            </list>
        </property>
    </bean>

I have a simple controller like this:

@Controller
@RequestMapping("account/*")
public class AccountController {

  public AccountController() {}

  @RequestMapping("signup")
    public String signupTestHandler() {
        return "signup";
    }

}

QuercusView looks like this:

}

Signup.php

<?php
echo 'This is php in Java with SpringMVC as the controller having a php based view resolver called QuercusView. Awesome!';

?>

When I access the resource at /account/signup , I get the following exception

exception

I'm using Tomcat + openejb + Spring3 as EJB container.

Thanks for helping out.

Please I don't know a lot about the inner workings of SpringMVC and Quercus, but I'm hoping someone can help me with some pointers about how to resolve this.

Thanks for helping out.

Edit

The only fishy entry in server startup log is:

INFO: OpenJPA dynamically loaded a validation provider.

Answer 1

work copy https://github.com/PaulWeb/TestJavaPhp Stanle was right maybe old version but they forgot to add start

protected QuercusContext getQuercus()
  {
    synchronized (this) {
      if (this._quercus == null) {
        this._quercus = new QuercusContext();
         this._quercus.start();
      }
    }
    return this._quercus;
  }

and if you want to pass from java to php then you have to use env.setGlobalValue
