LINUX下运行jar问题，在线等。。。急！！！急

Question

在linux下目录为/root/javamail/
在这个目录下执行
java -cp .:./sendmail.jar:./lib/mysql-connector-java-3.2.0-alpha-bin.jar:./lib/mail.jar:./lib/activation.jar com.javamail.SendMailMain
运行正常如果在root目录下执行这个
java -cp .:/root/javamail/sendmail.jar:/root/javamail/lib/mysql-connector-java-3.2.0-alpha-bin.jar:/root/javamail/lib/mail.jar:/root/javamail/lib/activation.jar com.javamail.SendMailMain
就报错。
还有就是写一个SHELL文件，直接使用 sh xxx.sh执行
我的sh文件是 $userpath ='./sendmail.jar:./lib/mysql-connector-java-3.2.0-alpha-bin.jar:./lib/mail.jar:./lib/activation.jar '
nohup java -cp "$userpath" com.javamail.SendMailMain
执行提示找不到MAIN函数
请问如何解决

还有,你在root目录运行，相应的库所在目录的相对路径都做了修改吗？？

将：
java -cp .:/root/javamail/sendmail.jar:/root/javamail/lib/mysql-connector-java-3.2.0-alpha-bin.jar:/root/javamail/lib/mail.jar:/root/javamail/lib/activation.jar com.javamail.SendMailMain 
改成
java -cp /root/javamail:/root/javamail/sendmail.jar:/root/javamail/lib/mysql-connector-java-3.2.0-alpha-bin.jar:/root/javamail/lib/mail.jar:/root/javamail/lib/activation.jar com.javamail.SendMailMain
