Welcome to JavaRanch
That error doesn't sound like a classpath problem nor a path problem. I presume you have quoted exactly what happened?
There will be more details about the error, particularly the line number where it occurred. It suggests there is no such method as getTextContent(). You will have to go back to that line and check it very carefully; if you have written gettextContent() as the name of the method that will be picked up as an error.
By the way: Don't put your work in the /bin folder. Make yourself a "javawork" or similar folder in some convenient location, eg My Documents, and keep all your work in that.
