一步步签名java小程序

发布于 2024-10-12 21:45:49 字数 1321 浏览 2 评论 0原文

我正在编写一个java小程序，它使用 org.apache.commons.net.ftp.FTP 从小程序在 eclipse 中工作的网页将文件上传到 ftp 服务器

。

我的项目包含 Uploader.java、FtpUpload_thread.java 和 commons-net-2.2.jar （ import org.apache.commons.net.ftp.FTP) 文件..

我使用 cmd 命令编译我的类：

javac *.java -cp *.jar

我将类放入 html 中：

<applet code="Uploader.class" codebase="./" archive="commons-net-2.2.jar" width="600" height="230"></applet>

但是当我尝试建立连接时出现错误：

java.security.AccessControlException: access denied (java.net.SocketPermission /*myftp*/ resolve)

所以我必须签名我的小程序..

我制作我的 jar 文件：
jar cvf Uploader.jar Uploader.class FtpUpload_thread.class commons-net-2.2.jar
< p>我生成密钥：
keytool -genkey -alias signFiles -keystore compstore

，然后输入程序所需的值。现在我有了 compstore 数据库文件

我签署了 JAR 文件
jarsigner -keystore compstore -storepass 通行证 -keypass 通行证 -signedjar UploaderS.jar Uploader.jar signFiles

和我有 UploaderS.jar 文件，

所以现在我有我的文件夹：

Uploader.jar
UploaderS.jar
compstore
Uploader.class
commons-net-2.2.jar
FtpUpload_thread.class

这是全部还是我需要其他步骤？

放置我的签名小程序并以权限运行它的 html 代码是什么？

谢谢！

原文

I'm writing a java applet that uses
org.apache.commons.net.ftp.FTP to upload a file to an ftp server from a webpage

the applet works in eclipse..

My project contains Uploader.java, FtpUpload_thread.java and the commons-net-2.2.jar (to import org.apache.commons.net.ftp.FTP) files..

I compile my classes using the cmd command:

javac *.java -cp *.jar

I put the class in html:

<applet code="Uploader.class" codebase="./" archive="commons-net-2.2.jar" width="600" height="230"></applet>

but when I try to establish the connection I get the error:

java.security.AccessControlException: access denied (java.net.SocketPermission /*myftp*/ resolve)

So I have to sign my applet..

I make my jar file:
jar cvf Uploader.jar Uploader.class FtpUpload_thread.class commons-net-2.2.jar
I generate keys:
keytool -genkey -alias signFiles -keystore compstore

and then I put the values that the program requires..
now I have the compstore database file

I Sign the JAR File
jarsigner -keystore compstore -storepass pass
-keypass pass
-signedjar
UploaderS.jar Uploader.jar signFiles

and I have the UploaderS.jar file

so now I have my folder with:

Uploader.jar
UploaderS.jar
compstore
Uploader.class
commons-net-2.2.jar
FtpUpload_thread.class

it's all or I need other steps?

what is the html code to put my sign applet and run it with permissions?

thanks!

我建议使用 java 插件而不是。标签。

您必须指定您的类所需的所有 jar 并使用签名的存档，

<object classid="clsid:CAFEEFAC-0016-0000-0000-ABCDEFFEDCBA" width="600" height="230">
    <param name="code" value="Uploader" />
    <param name="java_archive" value="UploaderS.jar, commons-net.jar" />
    <comment>
         <embed width="600" height="230" code="Uploader" type="application/x-java-applet;version=1.6" archive="UploaderS.jar, commons-net.jar">
             <noembed>
                 No Java Support.
             </noembed>
        </embed>
    </comment>
</object>

我还建议在您的 applet 类上放置一个包。

我不知道如何指定小程序使用的权限。

希望这有帮助。

I would recommend utilizing the java plugin as opposed to the <applet> tag.

You will have to specify all the jars required by your class and use the signed archive

<object classid="clsid:CAFEEFAC-0016-0000-0000-ABCDEFFEDCBA" width="600" height="230">
    <param name="code" value="Uploader" />
    <param name="java_archive" value="UploaderS.jar, commons-net.jar" />
    <comment>
         <embed width="600" height="230" code="Uploader" type="application/x-java-applet;version=1.6" archive="UploaderS.jar, commons-net.jar">
             <noembed>
                 No Java Support.
             </noembed>
        </embed>
    </comment>
</object>

I would also recommend putting a package on your applet class.

I am not sure how to go about specifying the permissions to use by the applet.

Hope this helps.
