我如何注入新的清单成小应用程序的现有罐子 [英] How do I inject new manifest into an existing jar for applet

问题描述

我有一个网站，已经工作多年（2）。但由于新的Java限制（2014年1月），我的小应用程序将被阻止。所以，做一些阅读后，似乎一切我所要做的就是改变清单文件;我甚至都不需要重新编译code。 （如果我错了这一点，请大家指正。）

I have a website that has been working for years (2). But since the new java restrictions (January 2014), my applet is blocked. So after doing some reading, it seems all I have to do is change the manifest file; I don't even need to recompile the code. (If I am wrong about this, please correct me.)

所以，我创建了以下清单文件

So I have created the following manifest file

Manifest-Version: 1.0
Created-By: 1.7.0_51
Permissions: sandbox
Application-Name: MyFarmingBusiness
Application-Library-Allowable-Codebase:http://mycompany.com/version_4/myapplet/
Caller-Allowable-Codebase:www.mycompany.com
Codebase: www.mycompany.com

然后到清单注入到我的瓶子

Then to inject the manifest into my jar

• 我在同一个目录中manifest.txt文件保存为罐子


• 在随后的Mac OSX终端I型：'罐子CFM MyGreat.jar manifest.txt

其结果是，我得到以下错误

As a result, I get the following error

java.io.IOException: invalid header field
at java.util.jar.Attributes.read(Attributes.java:410)
at java.util.jar.Manifest.read(Manifest.java:199)
at java.util.jar.Manifest.<init>(Manifest.java:69)
at sun.tools.jar.Main.run(Main.java:172)
at sun.tools.jar.Main.main(Main.java:1177)

有谁知道如何解决这一问题？

Does anyone know how to fix this?

另一种方法可能是重新再造的罐子。
所以我做了以下

Another approach might be to recreate the jar anew. So I did the following

• 来提取源：罐子XF MyGreat.jar


• 但后来，我还没有在这么长时间这样做了，我不知道如何从源头上重建的jar：源仅包含的.class 文件在目录 COM / myCompany中/...，并在一个名为 META-INF 目录清单。我尝试网上搜索，但我还没有对如何从终端。做到这一点运气

• to extract the source: jar xf MyGreat.jar
• but then, I haven't done this in so long, I don't know how to reconstruct the jar from the source: the source only contains .class files in directory com/mycompany/... and the manifest in a directory called META-INF. I try searching online, but I haven't had much luck on how to do this from terminal.

因此​​，也许有人能告诉我如何创建一个罐子从终端表现。我知道命令：罐子CVF MyGreat.jar MyGreat

So maybe someone can tell me how to create a jar with manifest from terminal. I know the command: jar cvf MyGreat.jar MyGreat

但我如何才能在清单？在哪里我把清单与关于的.class 文件，以便在最后，我得到一个目录的jar文件： COM 和 META-INF

But how do I get the manifest in? where to I put the manifest with respect to the .class files so that in the end, I get a jar file with directories: com and META-INF

推荐答案

您缺少冒号后<大骨节病>空格。这应该工作：

You are missing a space after the colon. This should work:

Manifest-Version: 1.0
Created-By: 1.7.0_51
Permissions: sandbox
Application-Name: MyFarmingBusiness
Application-Library-Allowable-Codebase: http://mycompany.com/version_4/myapplet/
Caller-Allowable-Codebase: www.mycompany.com
Codebase: www.mycompany.com

请注意额外的<大骨节病>空格在应用程序库，Allowable- codeBase的经过：和来电显示Allowable- codeBase的：项。

根据<一href=\"http://docs.oracle.com/javase/7/docs/technotes/guides/jar/jar.html#Name-Value_pairs_and_Sections\"相对=nofollow> JAR文件规范，值的定义是：

值：SPACE * otherchar新行*延续

value: SPACE *otherchar newline *continuation

如果您添加的空间，它按预期工作。

If you add the spaces, it works as expected.
