Re: Servlet/JSP - content-type
Calling RequestDispatcher.forward() erases any headers that have been set by the servlet, so your technique is not going to work. You will have to set the content type in the JSP page.

RE: Servlet/JSP - content-type
Hi Craig, Thanks for your quick response... I understand that RequestDispatcher.forward() erases any headers but I'm not setting any header info in the servlet. I want to set it in the jsp, how do I do that!! I've the charset info in the databean and I want to use that bean to set it in the jsp like I indicated in my previous mail: %@ page language=java % jsp:useBean id=controller scope=request class=apps.test.LoginController /jsp:useBean % response.setContentType(text/html;charset= + controller.getCharset()); % Any idea??

Hope I was clear!! Ah, missed that little detail ... I jumped to an incorrect conclusion when you said model 2 :-) In a JSP 1.1 environment (i.e. Tomcat 3.x), the character set used on the output page itself is determined by when the container calls response.getWriter(). There is no spec language to define this, so containers are free to do what they want -- and Tomcat calls response.getWriter() before your scriptlet has the chance to do anything. Therefore, your custom character encoding is ignored. In a JSP 1.2 environment (i.e. Tomcat 4.0), the container is supposed to wait before calling getWriter() until you fill the buffer (or flush it yourself). Therefore, your code should work in Tomcat 4. Thanks, -Ratnakar Craig -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Craig R.

RE: Servlet/JSP - content-type
Thanks Craig for clarification... I've another question on that line.. I'm actually using the i18n tag library in the same jsp page. That is, it looks something like this: %@ page import=com.cisco.appadmin.login.ui.LoginController % jsp:useBean id=controller scope=request class=com.cisco.appadmin.login.ui.LoginController /jsp:useBean %@ taglib uri=http://jakarta.apache.org/taglibs; prefix=i18n % i18n:bundle baseName=com.cisco.appadmin.text.resources.LoginRB locale=%= controller.getLocale() % / % response.setContentType(text/html;charset= + controller.getCharset()); % So, it should be OK in jsp1.2 spec ( i.e. Tomcat 4.x version), right!! The reason am asking is, looks like the tag i18n:bundle also sets the content type but I want the content-type to be set based on my databean. Based on your reason, this should work because am overwriting the content type with % response.setContentType(text/html;charset= + controller.getCharset()); %... And, container will wait until, the buffer is filled (or flushed).. Please correct me if am wrong!!
