签名的Applet无法加载 [英] Signed Applet does not load
问题描述
我有一个简单的HelloWorld小程序,我将其嵌入到HTML中。工作正常。但是,我将小程序放到了广口瓶中并在广口瓶上签名,但是却没有显示我不支持自签名广口瓶,我使用ICA颁发的证书进行了签名。
更重要的是,在1.7.51版本之前,我们从未遇到过此问题。
BTW:我经历了。
I've a simple HelloWorld applet, I am embedding that in the HTML. It worked fine. But I put the applet in the jar and signed the jar, but it does not load saying "Self signed jars can't be supported" I am signing using ICA issued cert. More over we never faced this issue before 1.7.51 version. BTW : I went through Oracle Documentation on adding parameters
According to it I tried to add following attributes in the signed MANIFEST.MF namely : Permissions: sandbox, Trusted-Library: true but this also did not help. I am not sure I'am missing something.
Manifest looks like this :
Manifest-Version: 1.0
Trusted-Library: true
Permissions: all-permissions
Application-Library-Allowable-Codebase: *
Caller-Allowable-Codebase: *
Codebase: *
Created-By: 1.7.0_45 (Oracle Corporation)
Name: HelloWorld$1.class
SHA1-Digest: xcxzcbxzcbxzcbxzcb=
Name: HelloWorld.class
SHA1-Digest: xaadfasfdasdfsafd=
Adding console logs :

Thanks. JE
Well I found the solution for this :
Check following three things.
1) Certificate has valid chain upto root and CA/ICA are public root.
2) Manifest.MF must have 2 attributes.
- Codebase: < location/hostname on which you are going to deploy your jar>
- Permissions: One of two values (Sandbox or all-permissions)
Check more information here.
