关于用Jbuilder9编译程序以及用weblogic8.1发布Serverlet的问题
1.首先是Jbuilder9没有集成J2EE的类（比如：javax.servlet.http.HttpServlet)所以在编译下面这个简单的程序时报错,程序为：
import javax.servlet.http.HttpServlet;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.io.PrintWriter;
public class ServletDemo extends HttpServlet{
public void doGet(HttpServletRequest request,HttpServletResponse response)
throws IOException,ServletException {
response.setContentType( "text/html;charset=GB2312 ");
PrintWriter out=response.getWriter();
out.println( " <html> ");
out.println( " <head> ");
out.println( " <title> Hello World! </title> ");
out.println( " </head> ");
out.println( " <body> ");
out.println( " <h1> Hello!这是服务器小应用程序ServletDemo的输出! </h1> ");
out.println( " </body> ");
out.println( " </html> ");
}
}
报错是：ServletDemo of class ServletDemo(src) failed to load superclass HttpServlet
于是我按照网上查的解决方法：在JB的configure servers里面配好了weblogic8.1,可是编译仍然没有通过。其实，我觉得也没道理通过，因为weblogic自带的jdk里面同样没有j2ee的类啊。
而我安装j2ee sdk然后设好环境变量，再到dos下用命令却可以通过编译。所以我想问一下Jbuilder如果要用来编serverlet的东西的话，究竟该怎么配置？
2.其次是weblogic上发布web应用程序，发布成功，用浏览器访问，却报错的问题：
我把ServletDemo打包为：ServletDemo.war，其中包括：
WEB-INF(文件夹）－web.xml,weblogic.xml,classes(文件夹）－ServletDemo.class
web.xml的内容为：
<?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/j2ee/dtds/web-app_2_2.dtd ">
<web-app>
<servlet>
<servlet-name> ServletDemo </servlet-name>
<servlet-class> ServletDemo </servlet-class>
</servlet>
<servlet-mapping>
<servlet-name> ServletDemo </servlet-name>
<url-pattern> /ServletDemo/* </url-pattern>
</servlet-mapping>
</web-app>
weblogic.xml的内容为：
<!DOCTYPE weblogic-web-app PUBLIC "-//BEA Systems, Inc.//DTD Web Application 6.0//EN " "http://www.beasys.com/j2ee/dtds/weblogic-web-jar.dtd ">
<weblogic-web-app>
<charset-params>
<input-charset>
<resource-path> / </resource-path>
<java-charset-name> ISO-8859-1 </java-charset-name>
</input-charset>
</charset-params>
</weblogic-web-app>
console上提示的测试地址为：http://172.25.0.5:7001/ServletDemo/
浏览器报错为：
Error 403--Forbidden
From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:
10.4.4 403 Forbidden
The server understood the request, but is refusing to fulfill it. Authorization will not help and the request SHOULD NOT be repeated. If the request method was not HEAD and the server wishes to make public why the request has not been fulfilled, it SHOULD describe the reason for the refusal in the entity. This status code is commonly used when the server does not wish to reveal exactly why the request has been refused, or when no other response is applicable.
另外我是把war包放在F:\bea\user_projects\domains\testdomain\applications的
查了下网上weblogic的那个布属问题似乎很普遍，我觉得应该是war包的结构或者两个xml文件写得有问题。小弟最后20分全部献上了，非常感谢！！！
