浏览器中的Java Applet策略问题 [英] Java Applet policy problem in browser
问题描述
大家好，我需要解决以下3个问题:
1.对于我的项目，我正在为毕业生和员工构建一个在线招聘系统.由于我只熟悉C/C ++和Java，因此我在Netbeans中选择了Java.我建立了一个applet，并使用run file命令对其进行编译.它从一个文本文件中获取了现有数据，而当我从Netbeans中运行它时，我工作得很好.这必须在Web上可用，所以我认为我会将applet嵌入到html文件中.一旦我尝试执行此操作，它就会开始给我java.io.FilePermission(读取)错误！所以我尝试使用策略工具，当我使用命令提示符和记事本时，我早先使用了策略工具，但是现在使用netbeans，这是第一次尝试，但我还无法弄清楚.它仍然给我一个文件读取错误.但是奇怪的是，当我通过netbeans运行它时没有错误.我应该编辑哪个java.policy文件?是项目文件夹中的一个还是用户目录中的一个?
2.有什么方法可以使内置在netbeans中的applet/JFrame变得可辨别吗?那是在计算机上，我可以只加载一些文件并运行它.因为加载jar文件很麻烦.您必须安装jdk才能运行它.像新手一样，我们不能只将他们的项目放在rar文件中，他们就可以解压缩并开始部署它吗?
3.是否有比仅从文件中读取更好的方法?就像我必须将其分发一样，是否需要在每台计算机上设置策略条目?使用JDBC/ODBC是否也需要在策略中授予权限.如果有比文本文件更好的方法，请告诉我！
任何帮助将不胜感激！
谢谢
Hi everybody I need help in the following 3 issues:
1. For my project, I am building an online recruiting system for graduates and employees. Since I am familiar with C/C++ and Java only, I chose Java in Netbeans. I built an applet and i used to compile it using the run file command. It took the existing data from a text file and i worked fine when i ran it from Netbeans. This has to be available on the web, so i thought i''ll embed the applet in a html file. Once i tried to do that it started giving me the java.io.FilePermission (read) error! So i tried using the policy tool, i had used the policy tool earlier when i used command prompt and notepad but now with netbeans it was the first try and i haven''t been able to figure it out yet. It is still giving me a file read error. But the strange part is that there is no error when i run it through netbeans. What java.policy file should i edit? the one in the project folder or the one in the user directory?
2. Is there any way to make an applet/JFrame built in netbeans disributable? That is on a computer i can just load some files and run it. Because loading a jar file is messy. You have to install jdk to run that. Like for noobs, can''t we just give them the project in a rar file and they can just unzip it and start deploying it?
3. Is there a better way then simply reading from files? Like if i have to make it distributable, will i have to set the policy entries in each computer? Does using JDBC/ODBC also require granting permissions in the policy. And if there is a better way than just text files, please do tell me!
Any help would be grateful!
Thanks
