Spring Roo Birt Integration Web.xml Configuration Error

Question

I have spring Roo app and i m trying to add birt environment in it.I am following this: https://spring.io/blog/2012/01/30/spring-framework-birt#birtviewer

The problem occurs when i am trying to add birt configuration class in web.xml. Here is the scenario:
1) I have webmvc-config.xml,application-context.xml which i need to add under contextConfigLocation. 2) I have another configuration class BirtWebConfiguration which i want to add in web.xml to load at startup.

Web.xml

<?xml version="1.0" encoding="ISO-8859-1" standalone="no"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.5" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

How do i manage it? Help please. Thnx.

Answer 1

This is how i was able to manage: My web.xml remains same as it should be ( default configured by roo)

web.xml

<?xml version="1.0" encoding="ISO-8859-1" standalone="no"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.5" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

The problem was with my extra configuration java class, which i have added into applicationContext.xml just by defining new bean definition

<bean class="com.palak.org.eclipse.birt.spring.example.BirtWebConfiguration" id="birtWebConfiguration"></bean>

Plus, i needed to remove this from my webmvc-config.xml :

<mvc:annotation-driven />
