File reported as missing but it is not

I am working on a java web application using struts that someone else wrote and I was getting errors about an import that was missing in some files so I looked around the project folders and found the file among the jsp files which seemed strange. So, I copied the file into the relevant package and the errors went away. When I went to run the program again on Tomcat I got this error:

"/WEB-INF/struts-html.tld" still exists and hasn't been changed or moved. I decided to delete the file I moved because the program still worked without it but I still get the error and I'm not sure how I could fix this.
Edit:
So I decided to refresh the webpage and a different error showed up:

The tld (tag library) files and their locations are specified in the web.xml file.
If you need new tlds, the jsp files which are using these tlds will look first in the web.xml to find info and location of the file.

In your web.xml you need to place taglib definitions right after welcome-page definitions. It worked for me.

ClassNotFoundException in Hibernate

I am getting the following error when I am trying to run my J2EE project. The same project was working before and I started getting this exception now. I am sure that all class are there along with their mapping files.
If I remove mapping of jobtitle from my hibernate.cfg.xml in the project, it is running.

means you do indicate a mapping in your hibernate.cfg.xml, but a mapping to a class which is not in the classpath of the j2ee project.
