I am attempting to put my Java applet into a .Jar so I can sign it, as currently it works locally but throws access denied exceptions when I attempt to run it remotely (it reads other files in the directory).
我试图将我的Java小程序放入.Jar中,以便我可以签名,因为它当前在本地工作,但当我尝试远程运行它时会抛出访问被拒绝的异常(它会读取目录中的其他文件)。
I created the manifest file correctly when creating the jar and checked it:
我在创建jar时正确创建了清单文件并进行了检查:
Manifest-Version: 1.0
Created-By: 1.6.0_25 (Sun Microsystems Inc.)
Main-Class: netApp
netApp was an applet and runs fine, and it does contain a main method:
netApp是一个applet并且运行正常,它确实包含一个main方法:

/*until here */
}

I have tried everything when creating the jar including just doing a:
我在创建jar时尝试了一切,包括只做一个:
jar cfm app.jar Manifest.txt *.*
When I try and run the jar from windows explorer or by running:
当我尝试从Windows资源管理器运行jar或运行:
java -jar app.jar
it fails. with the generic error:
它失败。与一般错误:
Could not find the main class: netApp. Program will exit.
netApp.class is definitely in the Jar.
netApp.class肯定在Jar中。
Thanks in advance for your help.
在此先感谢您的帮助。

Given the error message, it looks like it´s got the manifest correctly, but not the class itself. Run jar tvf app.jar
to have a look.
鉴于错误消息,它看起来像是正确的清单,而不是类本身。运行jar tvf app.jar来看看。
Your jar
command looks a little off to me... shouldn´t it be
你的jar命令对我来说有点不对......不应该
jar cfm app.jar manifest.txt *.*
