thank you for advance...

setkan CLASSPATH ...
cth set CLASSPATH=%CLASSPATH%;C:\Program Files\Apache Software Foundation\Tomcat 5.0\webapps\project\WEB-INF\classes

lepas tu mula compile
mulakan dari directory
C:\Program Files\Apache Software Foundation\Tomcat 5.0\webapps\project\WEB-INF\classes\beans
javac *.java

lepas tu compile file dalam directory
C:\Program Files\Apache Software Foundation\Tomcat 5.0\webapps\project\WEB-INF\classes\project1
javac *.java

utk ultra78..

classpath dah set dah..point to:--->>
C:\Program Files\Apache Software Foundation\Tomcat 5.0\webapps\project\WEB-INF\classes\

btul ker?

moderetor,....Terima kasih ye moved kan problem tu dlm board nih..

for your questions....
class LoginBean dah create?
class LoginBean dah include dalam classpath?
class LoginBean dah import dalam your source code?

dah buat dah semua tu...

anyway,thanks ya'

peachtree

Dekat file LoginServlet5.java tuh import sekali beans....pasal yg first tuh dlm package project1 yg lagi satu lak dlm package beans...That why error dia tulis "cannot resolve symbol"..dia tak jumpa class LoginBean dlm package beans tuh...hope can help u

zarcoss

packagekan folder beans jadi beans.jar. then masukkan dlm ...WEB-INF/lib/ jadi mcm ni -> C:\Program Files\Apache Software Foundation\Tomcat 5.0\webapps\project\WEB-INF\lib\beans.jar. Pas tu kat kawasan import ko tu, tambah line ni -> import beans.*;

pas tu compile. jgn lupa masa compile tu setkan classpath C:\Program Files\Apache Software Foundation\Tomcat 5.0\webapps\project\WEB-INF\lib\beans.jar

tapikan senang klu ko pakai JAVA IDE editor mcm netbeans / ECLIPSE. senang nak compile. Buat coding pun senang..
