And yes, the xml files are valid xml files at least in anything i've used to look at them (eclipse, ultraedit, notepad, ie) :).....

Thank you!

ps. the file:

<?xml version="1.0" encoding="UTF-8" ?>

"http://www.springframework.org/dtd/spring-beans.dtd">

Hi,

I have no idea about hybernate. But just confirm that you should have a ejbCreate() method(even if its empty) in all of your EJBs(session as well). If you don't have an ejbCreate method in your session beans, you will face prob. in generating them on SAP WAS.

Hope this help.

Thanks & Regards,

Daman.

Thank you for your help guys!

Solved, the hbm.xml files looked like valid xmls but after i saved them in ultraedit and i've opened them in eclipse there were 2 extra chars at the start of them (because utf-8???). So after i've deleted in eclipse these 2 extra chars and i've deployed the app, it started to work:) So now the frameworks/technologies used are:

springfrmwrk1.2.7, hibernater3.0, ajax using dwr lib and it's running smoothly under tomcat and sap too:)).

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.

Hi,

sorry but i'm new to netweaver and for me seems to be a little bit tricky to configure jaas in netweaver (based on the forum questions...), so could you pls tell me where and how is your jaas auth configured?

Pls see: http://static.springframework.org/spring/docs/1.2.x/reference/beans.html#context-create

maybe will help.....

Hi,

Pls check applicationContext-hibernate.xml if its a valid xml file. You can use any xml loader like XML spy to check the validity of the xml. Looks like there is a problem with one or more of the elements of the xml
