[servlet/JSP] afficher des images lues par ma servlet (ou ma JSP)

Marsh Posté le 17-07-2002 à 12:42:24

S'il vous plait, regardez si vous voyez un truc qui cloche, moi j'y arrive pas ! (IE6).
En fait, j'essaye de faire afficher au browser, des images lues par ma servlet.

Code :

// Method of a "Page" class
public void write (OutputStream out) {
// Reading of the tiff file (this.tempFile is a valid File)
PlanarImage image = JAI.create("fileload", this.tempFile.getCanonicalPath ());
/* // Test : the writed file is a valid tiff file --> the reading is OK !
* File outFile = new File ("c:\\temp\\JLdsWeb\\Test.tif" );
* RenderedOp op = JAI.create("filestore", image, outFile.getCanonicalPath (), "tiff" );
*/
// Writing of the tiff file in the received OutputStream
JAI.create("encode", image, out, this.FORMAT_NAME, null);
}
// my 1st JSP :page.jsp (to call the 2nd JSP witch have an other content type)
<%@page
contentType="text/html"
language="java"
errorPage="errorpage.jsp"
import="com.damaris.ldsweb.*,com.damaris.data.*,com.damaris.page.*,java.util.*"
%>
<html>
<head></head>
<body>
<IMG src=<%=request.getContextPath()%>image.jsp>
</body>
</html>
// my 2nd JSP
<%@page
language="java"
errorPage="errorpage.jsp"
import="com.damaris.ldsweb.*,com.damaris.data.*,com.damaris.page.*,java.util.*"
%>
<html>
<head>
<%
// pageToPrint is an instance of the class "Page" (getContentType ( ) give the String "image/tiff" )
response.setContentType(pageToPrint.getContentType ( ));
%>
</head>
<body>
<%
ServletOutputStream bOut = response.getOutputStream();
pageToPrint.write (bOut);
%>
</body>
</html>
