发帖数: 3845 | 1 I have put several java classes in a Jar file, one class
is the main entry, so I also put the main class information
in the manifest file.
However, when my class call j2ee classes (say java mail class),
"java -jar xyz.jar" always report can't file class error,
even i put -classpath c:\j2eeinstalpath\lib\j2ee.jar in the command.
There is no problem if i don't use jar file at all.
I wonder if this is the limitation of Jar? Thanks. | g*****g

发帖数: 3845 | 5 say if my main class name is SendEmail.java, there are
also other small clases. This SendEmail.java imports
javax.mail which is a part of j2ee.
if I don't jar all the classes. I use
% java SendEmail
at the command line, everything works smoothly.
However, if I jar everything in one SendEmail.jar, when I use
% java -jar SendEmail.jar
or
% java -classpath (path of j2ee) -jar SendEmail.jar
it will report run-time error, such as javax.mail.Address not found.
