Hi Martin,
thank you for your response,
the class name is correct.
I solved it with my FileServlet now.
The problem in the servlet was (I think) that when showing Image
it may not be set the response.setHeader(...), now the code look like these
To whom it may interest:
protected void doGet(HttpServletRequest request,
HttpServletResponse response) throws ServletException,
IOException {
FacesContext fctx = getFacesContext(request, response);
ValueBinding bind =
FacesContext.getCurrentInstance().getApplication()
.createValueBinding("#{facadeService}");
FacadeService bean = (FacadeService) bind.getValue(fctx);
if (logger.isDebugEnabled())
logger.debug("Bean=" + bean);
OutputStream out = response.getOutputStream();
Integer fileId =
Integer.parseInt(request.getParameter("file_id"));
UFile file =
(UFile)bean.getMileStoneService().getEntryManager().loadById(UFile.class,
fileId);
logger.debug("file="+file);
if(file != null){
response.setContentType(file.getContentType());
response.setContentLength(file.getContent().length);
if(file.getContentType().indexOf("image") == -1){
response.setHeader("Content-Disposition",
"attachement; filename=\"" +
file.getFileName() + "\"");
}
if(logger.isDebugEnabled())
logger.debug("sending file ...");
out.write(file.getContent());
out.flush();
out.close();
response.flushBuffer();
}
as you can see the changes are minimal...
don't forget to add the following to the web.xml:
<servlet>
<servlet-name>FileServlet</servlet-name>
<display-name>File servlet</display-name>
<description>Servlet used to view or download an Image or
document</description>
<servlet-class>main.org.jboss.portlet.milestone.servlet.FileServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>FileServlet</servlet-name>
<url-pattern>/FileServlet/*</url-pattern>
</servlet-mapping>
and the call for me from a jsp:
<h:graphicImage value="/FileServlet/?file_id=#{datatype.fileID}"/>
so again... thanks to anyone who responsed..
regards Omid
