用JB做一个JSP，SERVLET东西。先建立一个WEB MODULE，JSP存在里面。然后建立JAVA
Bean，SERVLET这些，JB会保存在比如project/src/com/smth/javaweb/
里面。可是在JSP中如果使用com/smth/javaweb的BEAN或者SERVLET老是说找不到。我现在
用土办法，把所有BEAN或者SERVLET打成个JAR文件，然后引入LIB。
请问正确的该如何配置？

If you wish to use those objects, you need import the path. You should know
that JSP is nothing but a 'servlet', basically, the jsp will be translated
into a servlet while it is compiled by the J2EE container. So, it's final
representation is a class.
Import in JSP is:
Do not forget to put double quotes on the package name.

Is this a special case in JB? he mentioned if he "把所有BEAN或者
SERVLET打成个JAR文件，然后引入LIB" then no problem.
But as I understand, you always need to import the class if you don't want
to use full path name of a class and the compiled JSP is not under
the same package as that of the class you use, no matter you
"打成个JAR文件，然后引入LIB" or not.

yes you are right, as long as your jsp page is in the different package,
you should always use import to find the file. em....
I have a question here, I remember that when I use a bean on the page,
I did not import the package, however, for some reason, when i tried use
JBuilder, the bean class can be found automatically by the jsp page.
I think there might be some place in the WEB.xml which could include
a default package for jsp pages.......
