在IE中java Web start启动jnlp文件,老是启动不了我的jar应用,在jrun中如何配置mime文件类型?

Question

标准 web.xml 中就可以配了 <mime-mapping>
  <extension>doc</extension>
  <mime-type>application/msword</mime-type>
</mime-mapping>要注意放置的位置，顺序错了可能无效

Answer 1

接上<mime-mapping>
<extension>jnlp</extension>
<mime-type>application/x-java-jnlp-file</mime-type>
</mime-mapping>

Answer 2

是不是指servers\default\SERVER-INF\目录下的default-web.xml文件?

Answer 3

在 webapp 中的web.xml 也可以，在 default-web.xml 配置也行，如果采用第二种方式，就要看用什么服务器了，因为不同的服务器默认的配置采用了不同的方式，比如 tomcat 中是在 conf/web.xml 中配的为了方便你的应用程序容易移植，建议放在 webapp 的 web.xml 中

Answer 4

我的是jrun服务器,我把文件给你看看,配置是不是错误?老是报如下错误:类别：下载错误在访问资源 http://tomtop2008:8100/jfdraw/helloworld.jar - null 时从服务器返回错误的 MIME 类型
我把配置文件给你看看:<?xml version="1.0" encoding="ISO-8859-1"?><!DOCTYPE web-app  PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd"><web-app> <display-name>Default Web Application Settings</display-name>

Answer 5

加上以下试试    <mime-mapping>
        <extension>jar</extension>
        <mime-type>application/java-archive</mime-type>
    </mime-mapping>

Answer 6

好了,上面的错误解决了,但又有新的错误:
类别：安全错误未签名的应用程序请求对系统进行无限制访问
未签名的资源：http://tomtop2008:8100/jfdraw/helloworld.jar
我要怎么签名?

Answer 7

修改 c:\Program Files\Java Web Start\javaws.policy 文件，改成以下内容
这样暂时去掉了权限限制，可以让程序运行起来。网上有很多对jar 文件签名的例子，自己可以找找，想挣你的分还真难!
grant {
    permission java.security.AllPermission;
};

Answer 8

哦,现在行了,原来是签名文件没有写好,而且是jar文件也没有处理签名的方式!再问问,客户端是不是一定要装jdk才可以调用啊?而且好像我的服务是1.5版,客户端的是1.4版还调用不了!
