http://nagoya.apache.org/bugzilla/show_bug.cgi?id=7747 File Upload Causes Tomcat-Apache to Block Summary: File Upload Causes Tomcat-Apache to Block Product: Tomcat 4 Version: Nightly Build Platform: All OS/Version: Other Status: NEW Severity: Major Priority: Other Component: Connector:JK/AJP AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] Hi folks, I've got the nightly build of apache-tomcat, running as a standalone server and with the Apache Server (via AJP13). File uploads are OK with the standalone server, but with AJP13, the first call to read() on the HttpServletRequest's associated Reader object (i.e. in order to get the file upload info) will cause the servlet to block. Note 1: this problem can be replicated on Tomcat 4.0.4 beta 2 Note 2: I couldn't replicate this problem with Tomcat 3.2.1. Sample code is attached. Any help would be appreciated!
