Subject: Problem with JNI, Tomcat 4.0.1 and FreeBSD
Hi everybody,
I´ve got an annoying error working with JNI and Tomcat 4.0.1 in a FreeBSD
machine. I call a native method from a servlet and it doesn´t work. I get
a core dumped... What do I have to do to make it works in Tomcat 4.0.1???
My classes an native code are below:
Is it necessary to do something in Tomcat to work with JNI??
From the servlet i make the following call:
Library.list(null, 0);
My class Library is like this:
public class Library{
static {
System.loadLibrary(mylib); // The sahred library is called libmylib.so
and this works fine
}
public native static void list(String name, int num);
}
The function header in Library.h (generated by javah -jni Library) is:
JNIEXPORT void JNICALL_Library_list(JNIEnv *,jobject,jobject,jint);
And I use this header in mylib.c
Thanks in advance

I guess that is the message displayed when JNI performs some illegal operation. I
suggest you to check your JNI code. The best thing would be to put *AfxMessageBox*es
at different places. One more thing... have you generated the .h file?

Not exactly... the browser get stuck for some minutes, as if it was trying
to access the library methods; but when it finish, the error is: The page

RE: Jetty .vs. tomcat
By any chance are you using JNI in your webapp? -Original Message- From: Steve Wong [mailto:[EMAIL PROTECTED]] Sent: Friday, March 01, 2002 3:10 PM To: Tomcat Users List Subject: RE: Jetty .vs. tomcat Hi mingfai, I am trying other application servers because I have some problems using tomcat in a production environment. The environment is Solaris 8, JRE1.2.2, tomcat3.3, Apache1.3.23 with mod_ssl and mod_jk. What I discovered is that when I use apache benchmark tool(ab) to generate many requests on apache, the java heap allocated in tomcat continuously increases. Up to a point that there is OutOfMemoryError. If I generate the requests on tomcat instead, there is no problem. I am using the OptimizeIt to see the above result. And What I can find in cvs log of mod_jk is that there was a memory leak bug in May last year. But this bug is said to be fixed. If I use Apache1.3.23 without mod_ssl, I find that the java heap remains stable. However, I discovered that the allocated memory of the java process of tomcat continuously increases. Because I am afraid that there will be OutOfMemeryError in the production environment. So, I restart the tomcat process regularly. Have you discovered the same things for your web application??

Steve. -Original Message- From: Ming Fai [mailto:[EMAIL PROTECTED]] Sent: Friday, March 01, 2002 4:05 PM To: Tomcat Users List Subject: RE: Jetty .vs. tomcat hi Steve, I'm a Tomcat user. from what I read on the web, I believe Jetty does outperform Tomcat significantly in static pages and also outperform Tomcat to a unknown degree in dynamic pages. so, why i still choose Tomcat? My main consideration is in scalability. Multiple instance of Tomcat can be run and load balanced with Apache and mod_jk. I believe it can achieve a very high scalability in handling simultanceous requests. Other considerations are: good integration with other Apache and commercial products, better support (i personally think the 'support' from Apache group is better than other open src groups), full implementation of JCP specification etc. And Tomcat should not be used together with Apache if there is heavy loading of static pages. Other than Tomcat and Jetty, Resin is also quite famous. And there are other commercial choice like WebLogic, JRun and Orion. You should make decision base on your need. In my opinion, if your site is small in scale, and requires a very good response time, then Jetty or Resin are your choice. Otherwise, Tomcat is a good choice in general and it is a proven product. It occupies about 50% of the servlet engine market as of mid 2001. (http://www.devx.com/judgingjava/articles/sixyears/printable /sixyearsp2.asp# fig7) Any comment are welcome!

RE: Tomcat Memory usage(Urgent!)
We faced this problem some time back. The memory usage seemed to increase to the point where no other application could be started. Many times we had to restart the NT machine itself. We did a thorough code-review and fixed the leaks. But even after that the Tomcat memory usage kept on increasing, although it came down, all of a sudden, to a very low value (600K). So garbage collection is being done more frequently, I would say. When there are more users connected to the Web server and accessing the Servlets/JSPs, the memory usage keeps on increasing... just to give numbers... we accessed our Web application using 50+ instances of browsers (IE, Netscape) and the memory shot to 200M. After some time (not immediately) when we stopped accessing the Web server it came down to 24M. You can find more pointers on JDC at http://java.sun.com. I remember discussing this topic there.

Excessive high usage of memory by Tomcat on NT
Hello all: We are facing the problem of excessive memory usage by our servlets (that call JNI functions). The memory usage seems to touch 50+ MB in 2000 Server but it drops down to 30 MB soon. But, this does not happen in NT. The memory keeps on increasing and there is a point in time when Tomcat occupies *all* the available memory. We are taking care of *garbage collecting* the objects frequently(by calling Runtime.gc()). Is there any other way by which we can have some kind of control over the usage of memory? Do we have to install a patch for NT (if something like this is available)?
