Question

我使用Eclipse创建了一个java应用程序。创建应用程序后，我希望能够自动更新。因此我尝试开始使用Java Web Start。这是我生成密钥库，将密钥库分配给jar文件，创建jnlp文件以及将所有内容上传到服务器的过程。

我在jar的位置的命令提示符下键入以下内容创建了一个密钥库：

keytool -genkey -keystore NameOfKey -alias MyAliasName

我被提示并回答了以下问题：

password: password1
rePassword: password1
What is your first and last name? [Unknown]: John Smith
What is the name of your organizational unit? [Unknown]: Development
What is the name of your organization? [Unknown]: App Co
What is the name of your City or Location? [Unknown]: Dallas
What is the name of your State or Province? [Unknown]: Texas
What is the two-letter Country code for this unit? [Unknown]: US
Is CN=John Smith, OU=Development, O=App Co, L=Dallas, ST=Texas, C=US correct? [no]: yes

Enter key password for <MyAliasName>
    (RETURN if same as keystore password):

我按了回来。并且创建了NameOfKey。接下来，我将密钥库分配给jar文件，打开命令提示符导航到密钥库的位置并输入以下内容：

jarsigner -keystore NameOfKey MyApplication.jar MyAliasName

Enter Passphrase for keystore: password1
jar signed.
Warning:
The signer certificate will expire within six months.
No -tsa or -tsacert is provided and this jar is not timestamped. Without a times
tamp, users may not be able to validate this jar after the signer certificate's
expiration date (2014-08-27) or after any future revocation date.

我的Myjnlp.jnlp文件如下：

<?xml version="1.0" encoding="utf-8"?> 
<jnlp spec="1.0+" codebase="http://example.com/Java/" href="Myjnlp.jnlp">
    <information>
            <title>This is my Title</title>
            <vendor>App Co</vendor>
            <homepage href="http://example.com" />
            <description>Testing Testing</description>
    </information>
    <security>
            <all-permissions/>
        </security>
        <resources>
            <j2se version="1.6+" />
            <jar href="MyApplication.jar" />
        </resources>
    <application-desc main-class="org.eclipse.wb.swing.SwingAppWindow" />
</jnlp>

我将MyApplication.jar，Myjnlp.jnlp和NameOfKey存储在位于http://example.com/Java/的我的网站上。我可以去http://example.com/Java/Myjnlp.jnlp我下载jnlp，当我尝试运行它时，我收到以下错误。

Unable to launch the application.
