Help!!!! Error 500??!!!

[June Low]

Greetings,     I'm using JSP to develop a website. I have one JSP page (named StudentDetails.jsp) which shows details of all the students. It has the following codes:       <%       Student students[] = stuBean.getStudents();     // where stuBean is the java bean in this page                                   for ( int i = 0; i < students.length; i++)                 {                     Student oneStudent = students[i];     %>    <%@ include file="StudentDetails.jsp" %>    <%        }     %>         Where StudentDetails.jsp is a page showing details of one student. However, when I try to run the page, I got the following error: Unhandled error! You might want to consider having an error page to report such errors more gracefully java.io.IOException: Error: Attempt to clear a buffer that's already been flushed         at com.sun.jsp.runtime.JspWriterImpl.clear(JspWriterImpl.java:115)         at D_0003a.jswdk_0002d_00031_0005f_00030.examples.jsp.Project.StudentDetails_jsp_1._jspService(StudentDetails_jsp_1.java, Compiled Code)         at com.sun.jsp.runtime.HttpJspBase.service(HttpJspBase.java:87)         at javax.servlet.http.HttpServlet.service(HttpServlet.java:840)         at com.sun.jsp.runtime.JspServlet$JspServletWrapper.service(JspServlet.java:88)         at com.sun.jsp.runtime.JspServlet.serviceJspFile(JspServlet.java:218)         at com.sun.jsp.runtime.JspServlet.service(JspServlet.java:294)         at javax.servlet.http.HttpServlet.service(HttpServlet.java:840)         at com.sun.web.core.ServletWrapper.handleRequest(ServletWrapper.java:155)         at com.sun.web.core.Context.handleRequest(Context.java:414)         at com.sun.web.server.ConnectionHandler.run(ConnectionHandler.java:139)   Is there anything wrong with my code? Pls help. TIA!   === Regards, June
