http://nagoya.apache.org/bugzilla/show_bug.cgi?id=5827 DataInputStream.readInt returns wrong values Summary: DataInputStream.readInt returns wrong values Product: Tomcat 4 Version: 4.0 Beta 1 Platform: PC OS/Version: Windows NT/2K Status: NEW Severity: Major Priority: Other Component: Catalina AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] We are using HTTP POST command to open a stream and pass a few arguments between a client and a servlet. Our client uses Java's core DataOutputStream.writeInt to send the binary data (configuration parameters). The servlet code is pretty straightforward - just create a DataInputStream and read out the values. Apparently, the integers are translated into different values. Consider the following: >From TryServlet.java: void process (String method, HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException { try { DataInputStream dis = new DataInputStream(req.getInputStream()); int b; while (true) { b = dis.readInt(); /*b = ((dis.readByte() & 0xFF) << 24) | ((dis.readByte() & 0xFF) << 16) | ((dis.readByte() & 0xFF) << 8) | (dis.readByte() & 0xFF);*/ //b = dis.readByte(); l++; //input += Integer.toBinaryString(b); input += "" + b; } } catch (Exception e) { System.out.println("Exception while reading input " + e); } System.out.println("Received raw input of length " + l + " \"" + input + "\""); -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
