Kind of difficult without seeing the code for PreReadError, but it looks like a servlet.context() issue. Take a look at this in the API.
Mark -----Original Message----- From: Edward [mailto:[EMAIL PROTECTED]] Sent: Friday, May 17, 2002 10:00 PM Importance: High I have a question,it is very puzzle to me.I have a class named PreReadError, it works well,it can read data from the file "error.data".For example: ... public static void main() { String str; PreReadError test=new PreReadError(); //notice here str=(String )test.getTable("Error0"); System.out.println("Found Error0"); System.out.println("It's value is "+str); ... } It works well.When I run it,it will show: Found Error0 It's value is 3 But when I use this class "PreReadError" in a servlet,for example: ... public class GetUserIdentity extends HttpServlet { public void doPost(HttpServletRequest request,HttpServletResponse response) throws ServletException,IOException { PreReadError test=new PreReadError(); PrintWriter out=response.getWriter(); out.println("<html>"); out.println("<body>"); //notice here String str=(String )test.getTable("Error0"); out.println("<p> It's value is "+str+"</p>"); .... } When I run GetUserIdentity,it should show: It's value is 3 But I got another result,it shows: It's value is null I put my files in follows: I use Apache Tomcat4.0 again,I install Apache Tomcat4.0 into D:\Program Files\Apache Tomcat4.0 I put my class GetUserIdentity.class and PreReadError.class into follows folds: I put them into D:\Program Files\Apache Tomcat4.0\Webapps\examples\WEB-INF\classes then I also put the file error.txt into D:\Program Files\Apache Tomcat4.0\Webapps\examples\WEB-INF\classes when I run it ,I can't get proper result.If the error.txt location is false, where it should be? I'm a newbie of JavaServlet,would you give me detailed steps to correct it? Please help me! Thanks in advances!
