BBjspWebResponse::getHeaderNames (Deprecated)

The BBJSP system is deprecated. For new development, use BBxServlet.

Description

In BBj 16.0 and higher, this method returns a BBjVector containing the names of the headers of this response.

This method considers only response headers set or added via BBjspWebResponse::setHeader(String, String), BBjspWebResponse::addHeader(java.lang.String, java.lang.String), respectively.

Syntax

Return Value	Method
BBjVector	getHeaderNames()

Parameters

None.

Return Value

a BBjVector containing the header names

Remarks

The example below shows getting the header names and values from a request within a BBJSP Servlet.

Example

This example demonstrates how this works in a BBJSP web-page

<html>
    <body>
        <h1>Hello from BBJSP</h1>
        <ul>
            <c:iterate data="<%= #getResponse().getHeaderNames() %>" id="headerName">
                <li><b><c:out value='${headerName}' /></b> = <%= #getResponse().getHeader(name$) %>
            </c:iterate>
        </ul>
    </body>
</html>

This example demonstrates how this works in a BBJSP servlet

class public MyServlet

  field private BBjspWebRequest request!
  field private BBjspWebResponse response!
  field private BBjspWebSession session!

  method public void service(BBjspServletContext context!)

    #request! = context!.getRequest()
    #response! = context!.getResponse()

    #response!.setContentType("text/html")
    s! = #response!.getOutputStream()

    s!.write("<html><body><h1>Hello from BBJSP</h1>")
    names! = #response!.getHeaderNames()
    s!.write("<ul>")
    for i = 1 to names!.size()
      name$ = names!.get(i-1)
      s!.write("<li>"+name$ + ":" + #response!.getHeader(name$))
    next i
    s!.write("</ul>")
    s!.write("</body></html>")
