Package not found error

[aarati teacher]

I m trying to deploy an apllication on tomcat.(tomcat 4.0.6 ).
The welcome page is mapped inside web.xml inside web-inf folder of my applicatin.When i type the url to access applicatin, it gives compilation error saying 'package *** not found in import.These packages are placed inside different folder structors and i hv placed all of them inside Web-Inf/classes folder.Even i tried setting the exact class path of these packages inside my environmental variable. But still not working.
Thanks for helps in adavance.
regards

Can you post your mappings from web.xml?

"aarati a.t",

There aren't may rules that have been put into place here on the Ranch, but one that we take very seriously regards the use of proper names. Please take a look at the JavaRanch Naming Policy and adjust your display name to match it.

In particular, your display name must be a first and a last name separated by a space character, and must not be obviously fictitious.

Thanks!

thanks for the prompt reply, now the tomcat is picking up the page mapped in web.xml file, but now new probs hv come up.
Now i m using usebean tag to create java bean object
<jsp:useBean id="eventProcessor" type="com.sourcetap.sfa.event.GenericEventProcessor" scope="application" />

the GenericEventProcessor class is placed inside package
com/sourcetap/sfa/event which is inside web-inf/classes inside my application folder

thanks

hi! meera
you are using wrong attribute in usebean tag you have to use "class" instead of "type".
you can only use 'type" attribute when object of that class already exist and you want to use it.But if you want to create object you have to use "class" attribute .
if you want to more hepl,you can email me on this Id: [email protected]

aarati,

A few things:

First, If you're using useBean to instanciate a class, the class needs to have a zero argument constructor. If you want to maintain a single instnace of the bean, (Singleton or otherwise) your best bet is to instanciate it in a context listener and bind it to context scope if necessary.

Second, If you are going to post more than a line or two of code, use the UBB Code tags. They will preserve your indenting which makes your code much easier to read (which usually results in more help).

Third, Please go back and re-read Bear's description of a proper display name. It needs to be a firstName followed by a space then a lastName.

Sorry, but it is not ok yet. As was stated in the numerous requests for you to modify your display name, it must be a first and a last name, not an initial.

Visit this page and adjust your display name as such prior to your next post.

Considering the number of times you have been asked, failure to comply at this point will result in the removal of your account.
