New to Java

I am new to Java and Eclipse and Weblogic.

I was give a .war file and told to simply edit a parameter that they thought was in one of the .jsp pages in the war file.

the only occurance of the parameter name "SearchProvider" is in the Search.class file located deep in folders under the WEB-INF folder.

the only way i could even find the parameter "SearchProvider" was with the use of an Effective File Search trial software.

I opened (barely) the Search.class file with windows notepad and its mostly jibberish but I can find the reference to "SearchProvider" in the class file.

I need to change this parameter.

When I import this into eclipse, I get the message there is no source file attached to the class file Search.class.

I added the entire class folder into the library. I tried to change the class source but all I have are just the files in the .war package.

I have tried changing the extension to .jar and this will let me add these files as a project, but I cannot edit this Search.class file no matter what I try.

My basic question is, Am I missing files from the client? Do I need more than just a war file?
