AW: Loosing Connections in a pool
Do you use a connection pool or do you have connections open for several hours ? Most databases have a maximal time frame for an open connection. So your software (or the connection pool you're using) has to be prepared to reconnect if the server closes the connection. -Ursprüngliche Nachricht- Von: Dan Randall [mailto:[EMAIL PROTECTED]] Gesendet: Freitag, 4. Mai 2001 20:32 An: [EMAIL PROTECTED] Betreff: Loosing Connections in a pool Hi, My tomcat application runs in a production environment for about 24 hours before it fails and must be restarted. During that time JDBC connections to Oracle become ignored and eventually disappear. A fair guess is that I am loosing memory, threads and resources in general until there is nothing left and only a restart cures the matter. Unfortunately, tomcat, rather than apache is serving much of the pages and graphics. That may be a contributing factor? I am using: Solaris 8 Oracle 8.1.7 tomcat 3.2.1 apache 1.3.19 and Java 1.3 Does anyone have an idea of what sort of problems I might be having? Any known resource leaks or threading issues? Thanks!!

tomcat starts taking full CPU
Hi, we have a problem with our tomcat 3.2.1 and Apache 1.3.12. (JDK 1.3.0_02 on Redhat 6.2) After about a day of operation, a couple of processes of tomcat start taking full CPU (for example, 4 processes at more or less 25% each, or 2 processes at more or less 50%). This is without tomcat even being used (the servlets and jsp pages are not being called). If tomcat is shut down, a couple of processes of Apache start taking full CPU immediately (as with tomcat). When restarting Apache, everything goes back to normal. Could someone have an idea what the problem is here ?? Thx. Geert.

NT Service question
Hi, I set up Tomcat to work as NT service and it works fine. Now I want to install Tomcat on several other computers. As Tomcat is installed in different paths on the different computers, I have to change the wrapper.properties (JAVA_HOME and TOMCAT_HOME) manually. My question is: Can I tell Tomcat to take the environment settings of TOMCAT_HOME and JAVA_HOME in wrapper.properties. This variables are already set for TOMCAT in normal mode. This could help me a lot. Thanks for any help Stefan

URL rewriting + RequestDispatcher.forward(...)
Hello, our configuration is as follows: Production: RedHat 6.1 IBM JDK 1.1.8 Apache httpd 1.3 9 Tomcat 3.2.1 Development: Win NT 4.0/Win 98 IBM JDK 1.1.8 Apache httpd 1.3 9 Tomcat 3.2.1 The developed application works fine with cookie browser support, but without cookie support, we run in one special problem. We use mod_rewrite in Apache httpd in order to handle URL's like: http://www.domain.com/shop/cashstyle.jsp;jsessionid=7y5yoj91n2?act=startste p=1 This works right. In the Java application we use response.encodeURL(...) to instruct Tomcat to generate an URL with the current session id. This method call we use in different JSP-files, but also in public methods of some JavaBeans, which generates HTML output. Let's construct the following situation: = We have a method, that construct the following URL: 1. with cookie support url_1 = http://www.domain.com/shop/cashstyle.jsp?act=startstep=1 2. with URL rewriting url_2 = http://www.domain.com/shop/cashstyle.jsp;jsessionid=7y5yoj91n2?act=startste p=1 When we now use the two constructed url's with the following method calls, we get different results: context.getRequestDispatcher(url_1).include(request, response); result: O.K., page with url_1 will be included ... context.getRequestDispatcher(url_1).forward(request, response); result: O.K., it will be forwarded to the page with url_1 context.getRequestDispatcher(url_2).include(request, response); result: O.K., page with url_2 will be included ... context.getRequestDispatcher(url_2).forward(request, response); result: FAILED, NO FORWARDING !!! We have now implemented as workaround a method, that looks for a session id in the path parameter, if a RequestDispatcher.forward(...) should be processed, and cuts it (;jsessionid=xyz24356). But this isn't a nice solution !!! QUESTION: Why doesn't work a forward with an URL with a jsessionid ? Thanks in advance, Ralf Zimmerer.

wired CLASSPATH behaviour

So we were putting JDBC Drivers of IBM (db2java.zip) on various places where we should be able to put them. 1. we put it into the $TOMCAT_HOME/lib/ to be include for whole tomcat. (did not work) 2. we put it into the CLASSPATH environment inside the $TOMCAT_HOME/tomcat.sh script (did not work) 3. we put it into $TOMCAT_HOME/webapps/our_app/WEB-INF/lib/ (did not work) 4. we unpacked the zip file and put the package tree under $TOMCAT_HOME/webapps/our_app/WEB-INF/classes/ -- YUHEE, it worked. the depressing part of it was, that db2java.zip and the _right_ Path to it was shown in the CLASSPATH variable on every of the setups (System.out.println, or shellscript ECHO). But the JDBC Driver Manager dumped no suitable driver found. It took me quite a lot of time to make the application run, cause there was no reason for the failure (If you have a package in your classpath, then you would suggest that it is loaded, right?). Anyways. The whole adventure brings me to the conclusion that either the CLASSPATH environment of Sun JDK 1.3 for Linux is not working properly or .. the dynamic loading of packages of TomCat is not fully reliable (which I honestly do not believe). Does anyone had similar Problems, and can someone give me a tip for where to put JDBC Driver packages inside a Webapp? (WEB-INF/lib/ I thought, but) thx. and regards roman

Re: AW: wired CLASSPATH behaviour
Hi Roman, It is not a limitation of the classloader, but it's just about the way Tomcat works: it only appends jar files to its own classpath (which seems not to be the same classpath that you define within your system) which are in the WEB-INF/lib directory of the application. So, as jar files and zip files have the same file format (in fact jar files are zip files), you just need to rename them to make them taken into consideration by tomcat). Benoît hay Noel, no I have not tried this. I thought about, but this would mean that the classloader does not support .zip files anymore. And I have not heard about any change like this. But it's still a good idea. I will give it a try and report results. thx roman -Ursprüngliche Nachricht- Von: Noel E. Lecaros [mailto:[EMAIL PROTECTED]] Gesendet: Montag, 7.

AW: HANDLER THREAD PROBLEM when accessing servlet
Hay, yes it's necessary to compile mod_jk.so, but it's really easy. get the Tomcat ressources and do exactly what is said in: http://jakarta.apache.org/tomcat/jakarta-tomcat/src/doc/mod_jk-howto.html#s6 2 The build depends on OS and Apache Version so normally the distributed binary is matching exactly one environment exapmle. (Probably not yours ;) If you start the startup.sh (default configuration) TomCat runs standalone and with the interface for Apache connections. (Port 8080 is standalone Version, Port 8007 is for mod_jk connections) Therefore you can try both. If Apache works well with your Tomcat you can remove the: Connector className=org.apache.tomcat.service.PoolTcpConnector Parameter name=handler value=org.apache.tomcat.service.http.HttpConnectionHandler/ Parameter name=port value=8080/ /Connector Entry form $TOMCATHOME/conf/server.xml to run Tomcat not standalone anymore.

Re: My growing memory problem resolved
Hei Eric,
thank you for your reply,
i will answer your questions below:
eric chacon wrote:
Wolle,
I think the problem may lie in your JVM: Setting a reference to the object
to null does not automatically free the memory--it just allows the garbage
collector to clear it whenever it runs.
In many (most?) JVMs, garbage collection is single-threaded. It may run at
a fairly low priority.
this was tested with JDK1.3.0_02 (Hotspot Server/client) and IBMJava2_1.3
Therefore, under stress testing, it is possible for you to eat up a lot of
memory before the garbage collector has a chance to pool it.
Yes, of course, I gave it a half day an nothing becomes free.
I had also see, that all process was cloesd (tool top under Linux).
One way to test this would be to let your process run under high load, and
then stop your load and watch over time to see if the memory is released.
If, in fact, it is a garbage collection problem, you have a couple of
choices: 1) upgrade your JVM and see if that helps. 2) pool your Heavy
Objects: create a store of them, and re-use them.
I have done something else,
I have synchronize the Object and use create only on Object:
class Servlet extends HttpServlet{
HeavyObject ho = null;
public doPost(request,response) throws IOException{
if (ho != null){
ho = new HeavyObject();
}
}
}
that works,
so the Object will only created once, but I have to synchronize the Object.
If you're doing load balancing/workload management, this might cause some
problems (you'll need to persist your objects to a common database), but if
everything's running on one machine, pooling might be an easy, convenient
solution.
Cheers,
Eric

Date: Mon, 07 May 2001 03:45:55 +0200
Hello ,
i have posted for a few day's a problem thats the Memory usage will
extremly grow up when I refresh a page very often
The Problem was, that I creat a heavy memory Object on each refresh.
Normally I have 81 processes run at all, when execute the stress-test
the processcount will rise till ~ 230. And each new Prcoesses will creat
a new Object.
When I stop the stress-test, the processcount becomes normal (~ 100) ,
but the memory usage won't fall.
But the new created Object have now refernces that points to them.
But why they don't becomes free My code is somthing like this:
public class servlet1 extends HttpServlet{
..
...
..
..
public void doPost(HttpServletRequest request,HttpServletResponse
response)
throws IOException{
try{
HeavyObject ho = new HeavyObject();
}
finally{
ho = null; // for testing implementet, but this gives the
memory not free, also
}
}
}
Is this a Bug in Tomcat ? Or is it a Bug from me ? Or som Java
misunderstood ?
Why will the Object not becomes free, when some of the Threads will be
closed ,
and the only reference is in the closed Thread ?

getResource() for files such as /WEB-INF/app.properties?
In the J2EE blueprint, there is an example of a configuration file
residing in the /WEB-INF/ directory which is loaded using getResource(),
see eg. http://java.sun.com/j2ee/blueprints/sample_application/qanda/
excerpt;
Here is some sample code that gets a configuration file from the
WEB-INF/ directory and parses it as XML.
URL myURL = null;
try {
myURL = context.getResource(/WEB-INF/mysettings.xml);
} catch (java.net.MalformedURLException ex) {
System.out.println(Malformed URL exception: + ex);
}
...
However, when doing this in tomcat 4.0dev (April 24th snapshot), the
getResource() method only returns null.
Is this supported in tomcat, or does getResource() only return things
that are in the classpath?
I there any other nice way of loading a property / xml / other file
from the WEb-INF directory?

mod_jk problems ...
Hello I am trying to configure the Tomcat 3.2.1 to work with Apache 1.3.19+mod_ssl. on a Linux SUSE 7.1 system. I have compiled the mod_jk.so, but I can't make it working with the Apache.. What I get when I'm trying to start apache with ssl enabled is : Syntax error on line 8 of /usr/local/tomcat/conf/mo API module structure `jk_module' in file /usr/local garbled - perhaps this is not an Apache module DSO? I've done everything I thought would be necessary : - adding DSO support to Apache - modifying the apxs script, so that the compilation of mod_jk ends up correctly (I conplied it on my platform from the sources which come in the jakarta-tomcat3.2.1 distribution) - loading the mod_jk module in the httpd.conf file.. I was going through the mailing archives in the last few days and saw that many people ran into the same kind of trouble as I did.. the main issue is that I couldn't find anyone who managed to make this work on a SUSE platform.. Can anybody please help me with this? I would appreciate very, very much any help, because I'm like in a kind of dead point.. I mean, the next step would be to change my linux for a Redhat or Mandrake, where it seems there are some chances to make the thing working.. :( Thank you in advance! Diana
AW: My growing memory problem resolved
You have to separate two things:
- memory usage inside the vm
this is what you see if you print out:
Runtime.getRuntime().totalMemory()
Runtime.getRuntime().freeMemory()
You have hardly any control about the
execution of the garbage collector. The
only contract that you can take for granted,
is that any JVM will do the garbage collection,
if it runs out of memory. All other things
(calling system.gc(), terminating a method,
setting all references to an object to null) are
just hints for the JVM that can be ignored.
From the java doc of System.gc():
Calling the gc method suggests that the Java
Virtual Machine expend effort toward recycling
unused object
- memory usage of the vm
this is what you see with top/ps/task manager
Even if all objects are garbage collected, that doesn't
mean that the size of the JVM shrinks, it is possible
that only the free memory inside the JVM grows for each
byte that is garbage collected. Wether the JVM is able to
decrease it's memory footprint is up to the JVM and the
underlying operating system.

Betreff: My growing memory problem resolved
Hello ,
i have posted for a few day's a problem thats the Memory usage will
extremly grow up when I refresh a page very often
The Problem was, that I creat a heavy memory Object on each refresh.
Normally I have 81 processes run at all, when execute the
stress-test
the processcount will rise till ~ 230. And each new Prcoesses
will creat
a new Object.
When I stop the stress-test, the processcount becomes normal (~ 100) ,
but the memory usage won't fall.
But the new created Object have now refernces that points to them.
But why they don't becomes free My code is somthing like this:
public class servlet1 extends HttpServlet{
..
...
..
..
public void doPost(HttpServletRequest request,HttpServletResponse
response)
throws IOException{
try{
HeavyObject ho = new HeavyObject();
}
finally{
ho = null; // for testing implementet, but this gives the
memory not free, also
}
}
}
Is this a Bug in Tomcat ? Or is it a Bug from me ? Or som Java
misunderstood ?
Why will the Object not becomes free, when some of the Threads will be
closed ,
and the only reference is in the closed Thread ?
Greetings,
Michael

Re: JNDI Datasource in Tomcat
Which database drivers are you using with poolman? I'm trying to use Oracle, but it's giving me null pointer exceptions when I run the test. Could you send your poolman.xml file? Thanks dave eric chacon wrote: You'll need some connection pooling software which doesn't appear to come bundled with Tomcat. There are several open-source connection pools. I've used PoolMan (www.codestudio.com), and found it to work pretty well. I did have a problem using JNDI, which I never successfully resolved, however: to make a Datasource (or any object) available through JNDI, you need to set up a proper security policy. I was never able to deploy a datasource that my servlets could read. Most connection pooling software packages don't require that you use JNDI (they come with propietary configuration files and such).

Sounds like you have server.xml set up to watch for http connections on port 8080.

RE: NT Service question
I don't think that you really want to do this - remember that EACH ACCOUNT has its own set of environment variables. If you run Tomcat as the System Account (the default account), I don't know if you can set the environment variables. As the software is currently written, what you are trying to do is not possible. You will need to get the source of jk_nt_service and find the portion of code that reads the file. Then you probably want to do something like replace %xxx% with the environment value of xxx. This doesn't seem to difficult, but I don't think its something that you really want to do - my experience with system variables is that they are a nightmare to manage. I would prefer files any day. Another thought on how to do this might be to have one wrappers file for each machine (i.e. wrappers-hostname.properties) and then when you install the service use the appropriate file name. You could then write your own installer which generates the appropriate configuration file based upon the environment variables.

Rick Somes times windows dont' know who localhost is. Try this: go to a command window, and ping localhost if you get host unknown or some other error other than 4 ping responses then you should edit your hosts file to include a line like localhost 127.0.0.1 ALSO: If you put a port number in there IE requires a protocol. so you can do localhost/blah/blah but if you do localhost:8080/blah/blah you need http://localhost:8080/blah/blah

Problem with JSP in Tomcat calling JavaBean that uses Xalan 2
I created a bean
that can be called from a JSP or by directly instantiating it
frommain(). The bean uses an XML file and an XSLT file, both of
which are valid. When I run the bean using the main() method, it works
correctly and prints the correct HTML output to the console. However, when
I call the bean from the JSP below in Tomcat, it gives me the following
error:
java.lang.IllegalStateException: Response has already been
committed
I already know that
an IllegalStateException"signals that a method has been invoked at an
illegal or inappropriate time. In other words, the Java environment or Java
application is not in an appropriate state for the requested
operation."
I don't know how to
solve it though. Any ideas?
Thanks,

RE: RE: Loosing Connections in a pool
1) Make sure you have enough open cursors (specified as OPEN_CURSORS in your
init.ora file).
2) See what cursors you've got open after running your page(s) by doing,
SELECT SQL_TEXT FROM SYS.V_$OPEN_CURSOR;
That'll tell you (more or less) what queries you've left open.
3) Make sure that you're closing all the connections, statements and result
sets you open. In general, you should close resources in finally blocks,
like,
ResultSet rs = stmt.executeQuery(SELECT 'X' FROM DUAL);
try
{
// Handle the data in the result set,...
}
finally
{
try
{
rs.close();
}
catch (Exception ex)
{
}
}
That way, if something crashes in the middle, you're still closing the
resource.

working directory getting too big
can anyone tell me if there is a way to manage the working directory, (where tomcat places the JSP compiled files .java, .class) my application automatically creates new JSP who get compiled and their files get put in the working directory. THEREFORE IT WILL GROW INDEFINITLY. What i am looking for is a way to delete automatically the JSP files in that directory after they are no longer needed.can tomcat do this? Or have them stored in a cache instead and setting a max size where the first in is the first out . Or something at the OS level. Any help, advice or directing me in the right path will be greatly appreciated. thanks in advance.
Re: Why does Internet Explorer think it is offline?
Your problem has nothing to do with Tomcat, or Apache, or any other server on god's green earth... The problem isn't a problem, it's just IE checking for an active internet connection and not finding one. Just click "try again" and it'll find the server. There is, to my knowledge, no way around it. Netscape, BTW, does not behave in this fashion. It's just a MonopolySoft, err, Microsoft quirk. regards, MTiffany

The http://jakarta.apache.org/tomcat/jakarta-tomcat/src/doc/tomcat-netscape-howt o.html document is completely NT-centric, to the point that it's not clear whether the redirector has been ported to Solaris or what it would be called if so. Considering the close relationship between Sun and Jakarta I'm surprised by what I seem to be seeing. I'm willing to RTFM if I can just find TFM. Thanks, David Boyce
RE: Why does Internet Explorer think it is offline?
I have found that IE really wants to have the HTTP:// in front of the I do use http. I use http://localhost/8080/examples/jsp/filename; localhost - On mine, it wants to change localhost:8080/whatever to local:8080/whatever and I get a similar error to what you mention. it shortens it to local?

AW: How to run through a DMZ firewall.
To answer your question, you should provide a bit more about what you want to achieve. (Or what problems you have) A typical firewall configuration doesn't block http on port 80.

Tomcat/Apache Q
Right now, I am running a web app. with a Tomcat 3.2.1 and Apache 1.3.12 configuration. I want to track all errors that are produced in the Apache error.log Does anyone out there know of a way to use the Apache error.log to track use and set it up as a simple reporting tool? One that will send an email if or when there is an error. I know the error log itself can't do this, but is there something that can? Thanks in advance for any feedback. ~~ Mark
Reload Servlet problems
I work with tomcat 3.2.1 and apache. I set reload=true in the server.xml. The servlet refresh well without restart tomcat. But, when I call a servlet by a jsp file and the servlet crash( ClassCastException for example) the servlet stop reloading for new one. I need to restart tomcat and I don't wont to restart it.

Servlet Tag
I hope that this is not off topic but I can find nowhere else to ask the question. I'm trying to use the SERVLET tag in a static html page causing the page to run the servlet as a server side include. I'm running Apache as my webserver. I've turned SSI on in my Apache configuration file. In fact, I am able to use #echo to throw the date back. I have my .shtml file in /apache/htdocs. I have my servlet in /jacarta-tomcat-3.2.1/webapps/examples/web-inf/classes. The .shtml file is properly served by Apache and renders everything but my servlet output. I can also directly call my servlet and see its output. Does anybody know what I may be doing wrong? Attached below is the contents of my .shtml file. Thanks in advance.

Title: RE: send response to browser and continue processing in servlet.s ervice() One way you can set the refresh header which auto checks for every 5 secs or 10 etc and displays the new data.

Re: Problem with JSP in Tomcat calling JavaBean that uses Xalan 2
Hi, Christopher
Just an idea to get you started. If I remember correctly, an
IllegalStateException can be thrown if you obtain a Writer to the
ServletOutputStream more than once, e.g. calling Request.getWriter, and then
calling Request.getInputStream. From your code, I can't tell whether you're
doing so, but I do know that a JSP will try to obtain a Reader from the request
object. That means any stream- or writer-related accesses in your bean are
suspect. You can also investigate by looking in the working subdirectory where
Tomcat creates the servlets from JSPs. The variable names be a bit cryptic, but
this should help you debug your exception dumps.
Hope this helps.
Regards,
Noel Lecaros
