The java.util.* and java.io.* classes are automatically included, so no specific jar file needed there. For javax.servlet.jsp.tagext.* and javax.servlet.jsp.* you need jboss_home/server/default/lib/javax.servlet.jsp.jar.
To compile, form the same directory as the file, enter:
java -cp jboss_home/server/default/lib/javax.servlet.jsp.jar yourfile.java
where jboss_home is the location where you installed JBoss and yourfile.java is the filename of the class you are compiling.
I'm currently compiling with JCreator.
Do I just add javax.servlet.jsp to the same directory and then compile my Java file? I've tried this and I still recieve the same build errors cause it can't find those libraries.
I have never used JCreator, but in the IDEs I have worked with, there is always a way of adding other jar files to the compiler's classpath. Find out how to do that in JCreator and then add the jar.
What directory do you mean when you say "the same directory"?
Also, I noticed I should have wirtten "javac -cp ..." (missed the 'c').
