Thanx, Craig, but something is wrong...
| Yes, dynamically setting the content type and character encoding is
| supported in JSP 1.2 (and therefore in Tomcat 4). You have three choices:
|
| * You can use a scriptlet to set the content type at the top of your
| JSP page:
|
| <%
| String contentType = "text/html;charset=xxxxx"; // Or whatever
| response.setContentType(contentType);
| %>
without success.
I am using Tomcat 4.0.1.
Also tried Tomcat 3.2.3 with very similar behaviour (and result).
JSP (start file):
<%
String contentType = "text/html;charset=windows-1250";
response.setContentType(contentType);
%>
Auto-generated servlet (from work directory):
response.setContentType("text/html;charset=ISO-8859-1");
pageContext = _jspxFactory.getPageContext(this, request, response, "", true, 8192,
true);
application = pageContext.getServletContext();
config = pageContext.getServletConfig();
session = pageContext.getSession();
out = pageContext.getOut();
// HTML // begin [file="/pokus.jsp";from=(1,2);to=(2,0)]
out.write("\r\n");
// end
// begin [file="/pokus.jsp";from=(2,2);to=(5,0)]
String contentType = "text/html;charset=windows-1250";
response.setContentType(contentType);
// end
// HTML // begin [file="/pokus.jsp";from=(5,2);to=(40,0)]
Note, that in generated servlet there is method response.setContentType() called twice.
HTML output contains "?" instead of accented characters.
| * You can do the equivalent to the above setting in a custom tag that is
| executed before the response has been committed to the user:
|
| String contentType = "text/html;charset=xxxxx"; // Or whatever
| pageContext.getResponse().setContentType(contentType);
The same result.
I have also tried "more coplex" approach:
I duplicated all the code for setting *out* object at the beggining of JSP...
response.setContentType("text/html;charset=windows-1250");
pageContext = _jspxFactory.getPageContext(this, request, response, "", true, 8192,
true);
application = pageContext.getServletContext();
config = pageContext.getServletConfig();
session = pageContext.getSession();
out = pageContext.getOut();
Without success... The output is the same.
Once the CT is set in response, it can't be changed.
I have discussed this behaviour of Tomcat's JSP engine with a few java gurus.
Result:
Possible Tomcat bug, becose JSP specification says:
"The contentType is ISO-8859-1 " IF NOT SPECIFIED.
Could you confirm this as the highest authority ( ;-) ) ?
| * You can use a Filter to set the response content type and character
| set based on the characteristics of the current request. However, any
| use of RequestDispatcher.forward() or <jsp:forward> will invalidate this
| setting, because all headers are removed when such a forward is
| processed.
As you mentioned, this solution is not suitable for all cases.
Thanx again for your time.
