and it's giving me this error page...
"C:\ bea \ user_projects \ domains \ mydomain.\ myserver.wlnotdelete \ extract \ myserver_sample01_WebContent \ jsp_servlet__display_email_entry.java"的编译
失败: C:\ bea \ user_projects \ domains \ mydomain.\ myserver.wlnotdelete \ extract \ myserver_sample01_WebContent \ jsp_servlet__display_email_entry.java:140: 无法解析符号
发生由于错误 /display_email_entry.jsp第19行:
ServletContext sc = this.getServletContext();
Compilation of 'C:\bea\user_projects\domains\mydomain.\myserver.wlnotdelete\extract\myserver_sample01_WebContent\jsp_servlet__display_email_entry.java'
failed: C:\bea\user_projects\domains\mydomain.\myserver.wlnotdelete\extract\myserver_sample01_WebContent\jsp_servlet__display_email_entry.java:140: cannot resolve symbol
probably occurred due to an error in /display_email_entry.jsp line 19:
ServletContext sc = this.getServletContext();
完全编译器错误::C:\ bea \ user_projects \ domains \ mydomain.\ myserver.wlnotdelete \ extract \ myserver_sample01_WebContent \ jsp_servlet__display_email_entry.java:140:

有什么提示吗?我真的是JSP的新手，这是我的第一次学习实践...在google.com上找不到....
any hint? I'm really new to JSP, and this is my first learning practice... can't find it by google.com....
谢谢！
推荐答案
Weblogic中的JSP在getServletContext方面的行为与Tomcat有所不同
JSPs in Weblogic behaves differently from Tomcat with respect to getServletContext
替换ServletContext sc = this.getServletContext();
到ServletContext sc = getServletConfig().getServletContext();
