Hi,
I made sure to double check everything before
I wrote here (I also just signed up and wrote
to the taglibs-user group).
My directory structure is like this:
onjava/
+- images/
+- WEB-INF/
+- classes/
+- com/
+- onjava/
+- lib/
+- com/
+- onjava/
My HelloTag.java is in the main onjava/ directory;
I compiled it with: javac -d WEB-INF\lib HelloTag.java
It created the com/onjava/ directories. I thought
nothing of it since HelloTag is in the package
com.onjava. Should I move HelloTag.class out of
the /WEB-INF/lib/com/onjava directory and right
into the /WEB-INF/lib directory?
This was the only part I wasn't positive on since
the instructions said to put it in the lib directory.
Thanks for your help and patience,
-alex
