    Hello,

    servlet-api.jar is missing, just add into classpath or put at proper place.

    I'm not an expert on servlets... but after some searching around, it appears this is a common error when folks don't have their javax.servlet library properly installed or their server on and/or configured. Do a search for "servlet" in the Java Tutorials section of this site.. or just do a basic search for "servlet" and you might just find your answer.

    Yep, I think so. There is a common error message, directed that import package is not perfectly execute.

    I'm using Geronimo Apache ver 2.0. If i want to run that servlet, i have to put .class in classes folder, am i right?

    But in folder WEB-INF don't have classes file. That mean i have to create it? What else i should do to run that servlet?

    Why it show those error when i compile it, before i add in geronimo?
