Multiple instances of tomcat
I have a tomcat 4-1-27 running on RedHat 2.4.21. Normally when you startup tomcat it will create a single instance, I have however about 28 created right away. I understand that they all share the same memory, but I don?t think this is a normal behavior. What can be causing this?

Wrong date / calendar after server has been running for long time
Hi, We are using Tomcat 5.0.28 running a Tapestry website for our company. A weird bug occurred and I am not sure if it's Java or Tomcat bug. Logging (new Date()).toString() or Calendar.getInstance().getTime().toString() normally returns the correct clock value at the timezone of our server (HKT or GMT+8). But when the server has continuously run say 2 days the log message showed that the toString() values of all Date objects changed to UTC and the time values are all offset by -8 hours. This caused very serious problem for our production application because we very much depends on the server clock to do various automatic scheduled jobs and logging user behaviours at different times. When the server has been restarted everything gets back to normal until pehaps 2 days later when it'd suddenly go wild again. I tried to set the default TimeZone but it seems to produce other unexpected effects in complicated ways such as affecting some date-sensitive 3rd party components (which we cannot make changes to) breaking many datetime dependent operations in them. I never encountered similar errors with non-web Java apps so I suspect this is more likely a Tomcat bug. But please correct me if I am wrong. Thanks a lot for help. Raymond

Re: Multiple instances of tomcat
All those are threads; tomcat creates 2 at first and the second forks the rest, if you kill either one tomcat will exit. I am asking because another server with the same configuration shows only one single thread. There are some problems with applications on the first server, which seem to be related to the memory. Both servers are running on 2.4.21 kernel and only one of them shows multiple threads when ps is executed, while both have tomcat 4.1.27 and j2sdk1.4.2_04. i am not sure what have I missed. Documentation mentions CATALINA_BASE that when defined implies multiple virtual hosts. I am not sure what I have done, while configuration files look exactly same. I appreciate your help.

Servlet Streaming file to client: Can't override file name
I wrote a simple servlet that streams a file to the requesting client.
Everything works fine except I can't figure out how to override the
filename that Tomcat provides by default to the client for the incoming
file. The filename presened to the client is the name of the web app.
The HttpServletResponse object that Tomcat passes to the servlet
provides access to an OutputStream object, and I see no way to set the
filename with an object of that class. If Tomcat passed a
FileOutputStream object (child of OutputStream), I could call a
constructor that sets the file name or file descriptor, but casting the
OutputStream to a FileOutputStream is not permitted. According to the
API, the OutputStream object that Tomcat passess to the servlet is
actually a ServletOutputStream object, which is an abstract child of
OutputStream. Is there a concrete child of ServletOutputStream that I
could cast it to, that would let me specify the filename? Is this
something configurable in Tomcat? Any other way to set the filename?
Here's my servlet code.
package FileSnatcher;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import javax.activation.MimetypesFileTypeMap;
/**

*/
public class FileSender extends HttpServlet{
protected void doGet(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException{
String file = request.getParameter(file);
MimetypesFileTypeMap mimeTypes = new MimetypesFileTypeMap
(C:\\Program Files\\Java\\jdk1.5.0_01\\lib\\mime.types);
String mime = mimeTypes.getContentType(new File(file));
response.setContentType(mime);
FileInputStream in = new FileInputStream(new File(file));
OutputStream out = response.getOutputStream();
byte[] buf = new byte[1024];
int i = 0;
while((i=in.read(buf))!=-1) {
out.write(buf, 0, i);

Why doesn't JSP precompilation solve this problem?
I'm using Tomcat v5.0.28 and have built a Struts-based application, using Tiles, to construct the web pages. When I deploy the application, and I newly visit each page, all of the text is displayed but the other visual elements (such as font-sizes, table layouts, colours, and other formatting set by CSS)appear broken. When I'm developing the pages and want to check that they are visually correct, I lose a lot of time having to re-hit the pages -- sometimes up to twenty times before they will render properly -- and it's driving me bonkers! I thought the problem might have something to do with the fact that the JSPs have to be compiled by Tomcat (Jasper) when they are first accessed. However, I now precompile all of my JSPs before deploying the application but exactly the same problems occur. I have no idea why this is happening. Can anyone explain why? And, especially, can anyone tell me how to resolve this? Sincerely, Frank Burns. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Why doesn't JSP precompilation solve this problem?
When I deploy the application, and I newly visit each page, all of the text is displayed but the other visual elements (such as font-sizes, table layouts, colours, and other formatting set by CSS)appear broken. are you using container-managed security? are your .css files in a different application context than the page? is your browser MSIE6? if so, this *might* be similar to a problem i'm having, which stems from the fact that tomcat will serve unauthenticated http 304s (Not Modified). so IE will render the page content it has cached, but if the .css files come from a different context (or maybe even the same one, i haven't tried it like that) IE won't reload them - and apparently it doesn't cache them like it does the page. and you get non-styled ugliness. haven't got a solution, short of filing the 403s thing as a bug, but this might help explain what you're seeing... --alex. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Exception on JDBCRealm Authorization
Alex, Thanks so much for doing the research on this. I do have a few questions. Has Tomcat acknowledged this and agreed that it will be fixed in 5.5.8? Any ETA for 5.5.8? Unless I'm missing something, this seems like it was be a pretty high severity bug. Or are you and I the only two people using JDBC Realms with 5.5.7? Is there no mechanism for putting out patch jar files? One last question... is it possible to extract a JDBCRealm jar file from 5.5.4 without having to completely uninstall and reinstall all of Tomcat? (and if so, what is the jar file name?)
