I am having a problem with generating a
JSP form that keeps the data after validation has detected bad user data. I have attempted and failed.
I created a bean that generates a dropdown with the correct data, but I can't seem to get the data to keep. I believe the reason is because it is instantiating another bean and not the one the jsp had generated. Below is the code for the bean and Jsp
JSP
<%@ taglib uri='tlds/update.tld' prefix='query' %>
<%@ page import="java.util.*" %>
<jsp:useBean id="formHandler" class="user.FormBean" scope="request"/>
<jsp:setProperty name="formHandler" property="*" />
<HTML>
<HEAD>
<TITLE>FSMO - (Placement Input Screen)</TITLE>
<LINK href="styles/style.css" rel="stylesheet" type="text/css">
</HEAD>
<BODY>
<H2>Create New Placement</H2>
<%//Formbean DD=new FormBean();%>
<FORM action='process.jsp' method='POST'>
<TABLE border="0" CELLPADDING=10 CELLSPACING=1 BGCOLOR="">
<TR>
<TD>Enter Date of Placement :<br><INPUT size="10" maxlength="10" type="text" name="DOP" value=<%=formHandler.getDATEOFPLACEMENT()%>></TD>
<TD><query
ropDown>Facility</query
ropDown></TD>
</TR>
</TABLE>
<TABLE BORDER=1 RULES=NONE FRAME=BOX CELLPADDING=10 CELLSPACING=1 BGCOLOR="">
<strong>Child Data</strong>
<TR>
<TD>Enter Child's First Name :<br> <INPUT size="10" maxlength="20" type="text" name="CFNAME" value=<%=formHandler.getCFNAME()%>></TD>
<TD>Enter Child's Last Name :<br> <INPUT size="10" maxlength="30" type="text" name="CLNAME" value=<%=formHandler.getCLNAME()%>></TD>
<TD>Enter SS# : <br> <INPUT size="10" maxlength="9" type="text" name="CSSN"value=<%=formHandler.getSSN()%>> </TD>
<TD><query
ropDown>Race</query
ropDown></TD><TD></TD>
BEAN
public void queryRace() throws JspException, IOException
{
try
{con=DriverManager.getConnection(host,userName,passWord);
stmt= con.createStatement();
ResultSet rs = stmt.executeQuery("SELECT * FROM RACE GROUP BY RACE");
pageContext.getOut().print("Select Race:<br> ");
pageContext.getOut().print("<select name=RACEID>");int i=8;
while (rs.next())
{ int RaceID = rs.getInt("RACEID");
String Race = rs.getString("RACE");
if (RACEID !="7")
{pageContext.getOut().print("<option SELECTED value=" + PARAM[i][i+1] + " size='10'>" + PARAM[i][i]+ " </option>");}
else{pageContext.getOut().print("<option value=" + PARAM[i][i+1] + " size='10'>" + PARAM[i][i]+ " </option>");}
}
pageContext.getOut().print("</select>");
con.close();
}
catch(Exception e) { pageContext.getOut().print("<h1>Invalid Username/password</h1>" + e.getMessage());
throw new IOException(e.getMessage());}
}
I used a tag to call dropdown. Please help.
Thanks
