Did I find a bug?
Hi, I am having a strange JSP compiler problem. The error message is as follows. First, notice that the lines cocerned are commented out! Still compiler compiling!

RE: find out the possible bottleneck webapp
Hi, What do you mean by SOMETIMES? Is it recurring problem at certain intervals? If it's early-on, it's more likely caused by first time compiling. If it occurs at certain intervals and you use large heap memory, its likely for garbage collection. You can find out the heap memory size allocated and using with Runtime APIS. Regards.

Compiling: both source and JIT. If you don't have enough main memory, this will accomany with excessive I/O as well as high CPU usage intemittantly mixed. Then you will have very long resonse time.

RE: ssl.SessionId Cache keeps growing
IMHO, there isn't much you can do about once you use sessions. The problem with session is that there is no natural way telling that session is ended and can be discarded! So system may have to keep session objects for long. For this reason, I always avoid to use sessions. If this is a major problem for you, alternative techniques might be worth trying!

Re: PDF problem on IE from JSP
PS; Dynamic generation of PDF files involves more than I thought. I noticed that iText may not generate the same byte strings for the same code. This is from iText manuals. In addition, database contents may change. So there is no way I can deliver the same byte stream in case IE reissues partial requests. Given this type of problems, the following header should be a reasonable compromise that works; response.setContentType(application/pdf;charset=UTF-8); response.setHeader(Content-Disposition, inline;filename=\Document.pdf\); // response.setHeader(Content-Disposition, attachment;filename=\Document.pdf\); response.setContentLength(baos.size()); response.setHeader(Cache-Control, cache); // to make IE work! response.setHeader(Pragma, cache); // to make IE work! response.setDateHeader(Expires, 1); Note that browser will cache for the first time. But will abandon next time for fresh copy! At least current my testing worked.

RE: How can I speed up and reduce load of initialization
How big is your main memory? Compiling (both source JIT) consumes lots of memory. If your main memory is small, it can take a lot of initialization time!

RE: How can I speed up and reduce load of initialization
Normally compilers are the memory hogs! A few things you can do is that; 1. If you use JSP, convert to servlets to avoid initialization phase compiling. 2. If your JDk is JIT (Just in time) compiler enable, disable it. You may have a bit slow execution. But should have satisfactory speed. 3. Increase memory size! I use 512MB and dual CPU. Still initialization taking significant time! Gavan Hood wrote: I agree it will take time, i have 64MB of ram. ...

Re: PDF problem on IE from JSP
Thanks! After changing no-cache to cache, it worked! But I am not sure whether this may deliver the same documents when diiferent documents are generated. The another problem was that inline didn't work for JSP urls, say, .../mydoc.jsp. So I have to use a servlet taking JSP as parameters and use RequestDispatcher. It works properly now. Regards.

RE: Custom initialization after startup
I need to start database before any servlet gets first request. So immediately after server start, initialize embedded database and make it ready for incomming first requests, of course, in a separate thread. The same goes not termination time. I need to have control passed immediately after all working servelts destroyed so that I can terminate database system NORMALLY! Currently it dies suddenly with Tomcat and every new starts starts with emergency recovery! Smooth normal shutdown is preferred. Regards. Caldarale, Charles R wrote: From: Jonadan [mailto:[EMAIL PROTECTED] Subject: Custom initialization after startup Is there any way I can perform custom initialization IMMEDIATELY after Tomcat startup automatically? Depends on what you mean by IMMEDIATELY. You'll at least need to insure that the Host attribute deployOnStartup is true (it is by default), and that you implement a ServletContextListener for each webapp of interest. Read section 10 of the servlet spec for details of the latter. -- View this message in context: http://www.nabble.com/Custom-initialization-after-startup-tp14937407p14947102.html Sent from the Tomcat - User mailing list archive at Nabble.com. - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Custom initialization after startup
PS: Yes, it can be done with ServletContextListener since we can check whether it is alive or not. However we may not sure whether it is system shutdown or app. shutdown. This is quite tricky. DBMS can use huge heap resources up to over 500GB on larger systems. This can be a problem without knowing the entire server is going down!
