for verfying that i am placing the class files in the right directory i wrote one more application code and tried to run , it worked absolutely fine ,I am using the tomcat 4.0 server and i placed the class files in the directory
it worked fine , but when i am using the struts framework i am facing the above error , i would like to mention what changes i have done before running the struts based web application
(1) I PALCED THE struts-config.xml file in the directory TOMCATROOT\webapps\application-root\web-inf (2) WITH THAT I HAVE PLACED THE struts.jar file in TOMCATRPPT\webapps\application-context\web-inf\lib
do i need to do some more changes or need to mention few more things..
i would also like t o mention what i thought of the probelm., i think that the problem coud be with the location where we should have a copy of struts.jar file in the tomcat server or it could be a version conflict that is may be there could be a stipulation about specific verison of struts.xml file to be used with this version of tomacat
I BADLY NEED HELP ON THIS
I WILL REALLY APPRECIATE ANY KIND OF SUGGESTION/HELP AS I AM RELLY STUCK IN THIS AND BEING A FIRST ATTEMPT I COUDNT THINK MORE AND NOT ABLE TO DO MUCH IN THIS....
Actually you will find better answer in the Struts user group for this question. Anyway...
Actually the problem is not with the location you have copied sturts.jar. You have not copied some other filed required by Struts in the webapps\application-context\WEB-INF\lib directory.
From the error message I think you are missing Beanutils in your lib directory.
The best way I would suggest to start your development is to, copy the struts-blank.war which you will have in the struts installation directory inside the webapps and rename it to your application context name. When you start tomcat this will create the necesary directory structure with all the required files and jars in it. From there on you can proceed to add whatever you want which is your application specific.
