Hello Yi, Jasper (on the server) seems to have a problem with the default User-Agent header set by HttpClient 3.0. You should try the following:
1. set the User-Agent manually to something different, like "Jakarta Commons-HttpClient" or some User-Agent string used by a browser, or an empty string 2. if that solves the problem, or leads to other exceptions that include fragments of the User-Agent string in their message, file a bug report against Tomcat/Jasper http://jakarta.apache.org/tomcat/index.html hope that helps, Roland "Yi Wang" <[EMAIL PROTECTED]> 02.12.2004 21:38 Please respond to "HttpClient User Discussion" To "HttpClient User Discussion" <[email protected]> cc Subject JasperExcetion Hi, Folks: Can someone give me some clue why I got the following exception?
