I have added spring.jar and commons-logging.jar, by the way i am also new to eclipse. but whatever i have done is correct i think.

The config file doesn't exist on the classpath, just like the error msg says.

thank you david, but i kept the demo.xml file in the package "sample", but still i don't understand where this error is creeping from .

[Hong Anderson]

Have you tried "sample/demo.xml"?

[sasank manohar]

but i kept the demo.xml file in the package "sample"

that's what i said in the previous reply. i kept demo.xml in sample package ie., sample/demo.xml. but no use.

[David Newton]

Is it being deployed?

You should use "sample/demo.xml", not "demo.xml" because demo.xml is in the sample package.
Do you understand what I mean?

[sasank manohar]

david, i didnot deploy this. i am not using any container, as it internally uses spring container.

yes, i understood kengkaj , i changed the code to this

Resource res=new ClassPathResource("sample/demo.xml");

but i am still getting the following error

is my dtd ok? i think nothing concerned about dtd coming in error right?

[David Newton]

The bean definition requires the fully-qualified class name of the implementation: you left off the package.

[sasank manohar]

thank you all, its working.

in DemoClient.java,

Resource rs=new ClassPathResource("sample/demo.xml");

in Demo.xml file,

<bean id="demo1" class="sample.DemoBean"

the above are the changes , i have made.and the code worked. now, i can carryon with my quest with springs. thank you.>

[Hong Anderson]

Congrats. Thanks for the update.
