hi istvan,
we are also migrating from websphere to netweaver.
But in spring framework we r facing problems.
We hav spring-beans.jar file in lib dir of Web Application. But When we are creating BeanFactory from xml as,
BeanFactory beanFactory = new ClassPathXmlApplicationContext ("client-config.xml");
clent-config.xml file contains :
[code<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
     <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer" >
          <property name="location">
               <value>conf/service-client/client.properties</value>
          </property>
     </bean></beans>
[/code]
But code is giving exception: ClassNotFoundException -org.springframework.beans.factory.config.PropertyPlaceholderConfigurer.
Wat is the problem ?
Kindly help.
We are also using JAAS for authentication.We are refering above code from our LoginModules login() method.
Regards,
sagar.
