RE: maximum length of form parameter
What if you were to assign some form of record ID that associated with a gene name so you could pass the ID's and not a descriptive name. This would reduce the number of characters in the stream.

RE: Programmatically Determine JVM Version used by Tomcat
One problem with this is that you have to know where the JRE for 1.5 was installed. There is nothing that guarantees that the install path is the default. You might try to get the version information from the binary that is running if the OS version supports it. It might be more appropriate to try to load a required class and report the error when you encounter it. Robert S.

Later, JAVA 1.5 is installed and JAVA_HOME updated, but the Tomcat service is still using 1.4 (verified by running tomcat5w.exe and clicking on the Java tab). This value either needs to be updated or the Tomcat service uninstalled and reinstalled with the new JAVA_HOME. Sometimes this doesn't happen causing issues with our application, so I'd like to write a program that detects when this situation occurs (JAVA_HOME set to 1.5, Tomcat using 1.4).

RE: Version of Java being used by Tomcat
That would show the version that is default for that console. You might do
better to look at the configuration for the Tomcat server to see where it
looks for the JRE. That would let you know for sure. If you are running on a
WinXXX platform and as a service, you could look at the settings for the
environment there as well.
An easy way would be to use log( System.getProperties().getProperty(
java.version );
or something like that. If you want to see all of the environment properties
you are running in, this should work.
.
.
.
Properties p = System.getProperties();
Enumeration e = p.keys();
while( e.hasMoreElements() )
{
String s = (String)e.nextElement();
System.out.println( s + = + p.getProperty( s )
);
}

Also remember that he said he had multiple versions of Java installed on his machine and it is possible that what Tomcat runs under may very well be different from what a console window would get. This is the case for me as well. I have three or four different versions of the JRE and what version is active in a process is dependent on the environment I set for that process. If you are coding a servlet, you can use System.out.println( System.getProperty( java.version ) ); and that will show you the version that is active for that process. Robert S.

After I added that readonly into web.xml, I can put files into /webapps/incoming. Right now it is ok for me. Because user ONLY can put files under /webapps/incoming dir. Also, in this way, tomcat does not require userID and password. Now there are three questions: 1. How to config to force using userID and password? I add putusero1 into tomcat-users.xml, it's useless. [Robert Harper] Look at the documents. You'll have to set up the security and determine what kind of authentication you want. This may be version dependent so I won't go into too much detail here. I am using 5.0 because that was the newest version when I developed my app and I don't see a big reason to change right now. 2.

Use the security-constraint area in the web.xml file to set what you will and won't handle and other options. See the Tomcat documentation for your version on where and how to do this. servlet-mapping servlet-namePUT/servlet-name url-pattern/MyPUT/PUT-Handler/url-pattern /servlet-mapping 3. How to turn on client request log in tomcat side? [Robert Harper] I used log() method inherited from HttpServlet to log my messages. I created a little wrapper method so I could easily force certain patterns to the messages. Where they land is in the logger specification in your web.xml configuration in the servlet's context. The easiest way to configure the logging directory, file names, and other settings is with the admin app. What version are you using? Thanks Jimmy -Original Message- From: Robert Harper [mailto:[EMAIL PROTECTED] Sent: Friday, January 26, 2007 12:07 PM To: 'Tomcat Users List' Subject: RE: HTTP PUT - HOW TO CONFIG? The problem is that the default servlet is handling the request(s) unless you have some other servlet do it. By default, the doPut() will check to see if the readonly property has been changed to false. If it has not, default behavior, it will return the forbidden error. If you change this to false, then you loose control of security and anything sent via a PUT will be allowed. You may want this but it also leaves you open to easy attacks. If you are sure you want to do this, try adding the following to the default servlet's configuration in the web.xml file.

RE: HTTP PUT - HOW TO CONFIG?
The problem is that the default servlet is handling the request(s) unless
you have some other servlet do it. By default, the doPut() will check to see
if the readonly property has been changed to false. If it has not, default
behavior, it will return the forbidden error. If you change this to false,
then you loose control of security and anything sent via a PUT will be
allowed. You may want this but it also leaves you open to easy attacks.
If you are sure you want to do this, try adding the following to the default
servlet's configuration in the web.xml file. Where this is could vary based
on the version of Tomcat you are running.
init-param
param-namereadonly/param-name
param-valuefalse/param-value
/init-param
Most would prefer not to do this and would prefer to either write a filter
or servlet to track the PUTs and have something to protect your system.
You will not see anything in a log file because the default servlet does not
write anything to the logs when it refuses the request.
For Tomcat 5.0 the document to read on what the default servlet does and
doesn't do would be found here.

RE: XML Parse problem in a webapp context.xml
There are probably required elements that are not present. The DTD/XLS could specify elements as being required and you can get an error during validation in processing the Resource tag. You may not be able to create an empty resource element or there are attributes that are required. Try modifying your resource to something more like: Resource auth=Container description=User database that can be updated and saved name=UserDatabase type=org.apache.catalina.UserDatabase / My simple guess would be that it is trying to invoce a method on a class defined in the type attribute. You are not providing one so it would be a null argument. I'd have to dig in code to see for sure but it may not protect against that because a resource without a class to manage it, makes no sense at all. Robert S.

RE: HTTP PUT - HOW TO CONFIG?
I don't know if Tomcat would be able to do this without some code. It is not
intended to replace Apache, IIS, or some other web server. It is intended to
be a Java Servlet/JSP container.
You might try creating a servlet that does something like this
public void doPost(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException
{
String buf = req.getRequestURL().replace( my_context_path,
/cgi-bin/put.pl);
resp.sendRedirect( buf );
}
So let's say you have a URL like http://www.myserver.com/realitycheck, then
replace to req.getRequestURL().replace( /realitycheck, /cgi-bin/put.pl )
Then use that in the redirect.
Someone else might/will have a better idea but it seems to me you are trying
to kill a fly with a water cannon where a fly swatter would be more
efficient.

RE: HTTP PUT - HOW TO CONFIG?
I don't know if it can or can not. I never tried because I wanted to write Java code to handle by web requests rather than learn PL script. If you don't want to write Java script, then why not just use Apache since you seem to know how to configure it just fine. Tomcat can do some simple web server functions as long as you don't turn off some features. Tomcat is more like a playground with a manager that will set what servlet gets to play were and when and who gets what request. The Tomcat Mailing list is primarily for questions and answers on configuration, running, and coding for Java servlets in the Tomcat servlet container. Some people are bright, much more so than me, and are willing to answer questions that don't really have much to do with the Tomcat servlet container. -Original Message- From: Zhan, Jimmy [mailto:[EMAIL PROTECTED] Sent: Thursday, January 25, 2007 4:03 PM To: Tomcat Users List Subject: RE: HTTP PUT - HOW TO CONFIG?

Hello there,
I am creating a configurable errors file which gets loaded as a
properties file from an init servlet:
import java.io.IOException;
import java.util.Properties;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
public class ErrorInitServlet extends HttpServlet {
static Properties errorProps = new Properties();
public void init() throws ServletException {
Properties props = new Properties();
try {
props.load(this.getClass().getClassLoader().getResourceAsStream(
/error.properties));
}
catch (IOException e) {
e.printStackTrace();
}
}
public static Properties getErrorProperties() {
return errorProps;
}
}
The error.properties file looks like this:
error.required.field=Required %s
error.invalid.entry=Invalid %s
error.unknown.entry=Unknown %s
I created an ActionErrors.java file:
package org.coffeebreak.wrapper;
import java.util.Formatter;
import java.util.ResourceBundle;
/**
* @author jdekker

public class ActionError {
private final ResourceBundle m_resource;
public ActionError() {
m_resource = ResourceBundle.getBundle(error.properties);
}
public String getMessage(String id, Object... parameters) {
String value = m_resource.getString(id);
if (null != value) {
StringBuilder builder = new StringBuilder();
Formatter f = new Formatter(builder);
f.format(value, parameters);
f.flush();
return builder.toString();
}
return value;
}
}
I had my ant build script move the error.properties to:
TOMCAT_HOME/WEB-INF/classes/org/coffeebreak/wrapper/

get:

RE: Configurable Errors
In my servlet, I load a properties file that is in my [context_path]/classes
directory with the following line of code
m_resource = ResourceBundle.getBundle( ctimpact, Locale.getDefault() );
This works fine for me. You could try removing the .properties part of the
file name. The API may be adding it by default. Also maybe move your
properties file to the classes directory.
I hope that helps.

Dear Mr. Harper,
Thank you for the response!
I set the path inside the ActionError constructor as follows:
public ActionError() {
m_resource = ResourceBundle.getBundle(/error.properties);
}
I thought the / meant the root directory inside
CATALINA_HOME/WEB-INF/classes/.
Since, my error.properties file is going inside the
CATALINA_HOME/WEB-INF/classes/org/coffeebreak/wrapper/ directory via
my Ant build script, I rewrote the code inside the constructor as:
public ActionError() {
// I removed the slash
m_resource = ResourceBundle.getBundle(error.properties);
}
And then it gave me that Missing exception...
What am I possibly doing wrong?

Unfortunately, when trying to access the site from the outside, I get a page not found error. Since that didn't work, I tried with Tomcat 5.5.20 on Windows 2003. I used port 9191 this time. Also added a rule for 9191. And I got the same results. As far as I know, the ports are open on each machine and there are no software firewalls running.

RE: Having trouble making Tomcat available from outside the network
I usually look in the logs I set up for my contexts or in the stdout.log. You should see some logging from requests having hit filters, if you are using them. The other thing you could do is start the network monitoring tool that comes with Win 2003 server, or some similar tool, and watch activity on the ports in question. If the requests aren't making it to the server, then the problem is further up the chain. Do you see the request hitting the firewall? Robert S.

RE: Client request times out
I think the bigger question is why does it take that long to run? I can't think of too many people that are willing to wait that long for information. Personally I'd give you 30 seconds and then I'll never use something that slow again. If you are accessing data, try adding indexes or a data redesign to speed things up. A simple index based on key data can speed up searches exponentially. Just a thought. Most of my problems have been my problems not something Tomcat was doing wrong. Robert S.

RE: How do I print out line of code that caused the error?
The problem is that the JSP is not compiled on the browser. Even if it was,
you would be bound on functionality provided by the particular browser. The
servlet container might send an error in the response but that would be up
to the container provider as well. Because these behaviors are not bound by
standards, you can't count on them to always be there if you once had what
you want. There should be server side logs that will show your problem.

Thanks. So there's absolutely no way within the web browser to print
out the line of code that caused the error? In the example, the line
i would've liked to see in the web browser would have been:
String v1 = session.getAttribute(attr);

RE: Is Tomcat a good solution for me?
If your content is static pages, the Apache might be a better option. If you are using Java Servlets for dynamic content, then Tomcat would work fine. You may have to adjust some of your code to match changes in the runtimes. If you are using ASP, I don't think Tomcat is for you. You should be able to run PWS and Tomcat at the same time on different ports. Remember that Tomcat is a Java centric servlet container.

RE: Re[2]: Communication with a standalone java program from servlets (embedded tomcat). RMI?
The big thing is scalability. If you leave them separate, you can put Tomcat in one system and have your app running in another. This will help with loading if either process ends up using a lot of CPU. Using RMI you can make it loosely coupled where only the interface is known. As long as the interface is not changed, you don't have to worry about changes in one affecting the other. Robert S.

RE: tomcat memory usage questions
The memory should peak at some point and the go up and down with need. There are a few things you have to be aware of though. The garbage collector is a very low priority thread so if your server never has a dull moment, you end up exhausting memory just because the garbage collector does not get a chance to run. Care in development should be taken with respect to use of objects and having circular references. You can cause memory leaks with circular references because you might leave free and object from the servlet but then have two objects referring to each other and the GC will not see them as having gone out of scope. Another thing to think about is if you are doing a lot of string concatenation the StringBuffer object is much better to use than the String object. StringBuffer will be easier on memory and more efficient. Robert S.

Struts Spring Hibernate 3.0 Mysql 5.0 tomcat 5.5 Linux Fedora Core 4 After the system went live, I have been monitoring the CPU and memory usages. I dread the outOfMemory errors and am a little paranoid about it. There are 2 main processes I am monitoring, tomcat and mysqld. The tomcat process memory usage is slowly creeping up...after 8 hours of application usage it is at 13.3% and the mysqld memory usage is at 1.3%. I am wondering what kind of pattern I should be observing for the memory usages. Should it go up and then down again (like the CPU usage)? Or is it ok for it to slowly go up (the way it is doing right now)? The swap memory is not being used, so I am guessing thats a good thing. Also, someone told me that hibernate and spring will try and cache everything it can, which could be the cause of the memory creeping up slowly. Is this true? and if it is, will this be a problem when the memory gets to a high number like 80 or 90% ?

Check your definition of the servlet in the [app_root]/WEB-INF/web.xml file. There is a reference to where the filters are located. You probably need to either create this class or remove the reference from the web.xml file. Robert S.

I think the problem has more to do with Tomcat on a mainframe and conversion
from ASCII to EBCDIC. The XML parser is having problems translating the XML
records in the configuration files. Does anyone have experience with Tomcat

To use CompressionFilter you
1)override doFilter method to provide filtering response via previously
defined 'FilterChain'
2)wrap your regular response as a CompressionServletResponse before sending
back to client (as in this example from Kief Morris)
public void doFilter(ServletRequest request
ServletResponse response,
FilterChain chain)
throws IOException, ServletException
{
long startTime = System.currentTimeMillis();
chain.doFilter(request, response);
long stopTime = System.currentTimeMillis();
System.out.println(Time to execute request: + (stopTime -
startTime) +
milliseconds);
}
Later on in the service() doGet() or doPut() methods check the response to
build the appropriate CompressionServletResponseWrapper
if (response instanceof HttpServletResponse) {
CompressionServletResponseWrapper wrappedResponse =
new
CompressionServletResponseWrapper((HttpServletResponse)response);
wrappedResponse.setCompressionThreshold(compressionThreshold);
if (debug 0) {
System.out.println(doFilter gets called with compression);
}
}
Make SURE the actual class (which is displayed from your web.xml)
is on your classpath or your class is located in
$TOMCAT_HOME/webapps/NameOfYourWebApp/WEB-INF/classes)
The example $TOMCAT_HOME\webapps\servlets-examples\WEB-INF\web.xml displays
filter

RE: Handling huge amount data
I've seen the memory rise and fall so if the GC releases memory, it should be returned to the OS. It would be my guess that you may not be handling removing all references to an object the way you think you are. You can test this out by adding a log in the finalize() method of your object and see if it ever gets called. You could have a reference somewhere in a static class or some other class that you have not released as well. As long as there is more than one reference to an object, the GC will not free it. I had found this to be the case in something I was working on. It is hard to find at times but you should be able to find it. The other thing to remember is that the GC is a very low priority thread and if the system is very busy, it may not run as often as you would like. Robert S.

I noticed that when I call my logout method (It calls session.invalidate()) or my user session expieres the memory is still in use, in other words, the memory is not cleaned. Windows only reports the size of the application in memory. Once Java requests memory from the OS, I don't believe that it ever returns it. So, the memory size reported by Windows Task Manager will only increase, never decrease. You need to look at the memory behavior /inside/ the JVM, which is much more complicated than what Windows Task Manager displays. There are some tools that will help you see into a JVM, including simply using the verbose GC settings when starting your JVM, as well as some other 3rd-party tools that can give you a lot of information about the JVM upon which Tomcat is running (LabmdaProbe comes to mind: http://www.lambdaprobe.org/d/index.htm).

Using Tomcat's internal bean server.
Ive tried this before so let me rephrase this. I am using Tomcat to perform the authentication and I have an app that is adding new users to the tomcat-users database just fine. The problem is that Id like to get the role and group attributes back. I would rather not keep the information in another database and just use the existing MBean. The Users:type=UserDatabase,database=UserDatabase bean only has methods for finding users and getting their full names. Is there some way to do this or can I change the mbeans-descriptors.xml file to add methods I need that wrap the UserDatabase.getGroups() and UserDatabase.getRoles() methods? Robert S.

User database and user attributes
I am using the Tomcat user database to hold information for users. What I need to do is retrieve the group a user is in from the database. My problem comes when I have a servlet add a new user, assign it to a roll and a group, then try to access the user from another servlet running in the same context. I often get exceptions thrown when I call the save() method on the user object stating that Tomcat cannot rename the tomcat-users.xml to tomcat-users.xml.old. The user info is still in memory and if enough time passes or the server is stopped, the data eventually gets flushed to disk. There are methods for finding the user, finding a roll, and finding a group, but I dont see a method for finding a group for a given user using the MBeanServer(). I had been using the XML libraries to load the database and then search through it finding the user then getting the assigned roll but it only works when the new user information is flushed to disk. What would be the best way to do this? Robert S.

Can't this exception be the result of the user hitting the STOP button, or
simply closing the browser? I.e., this can happen all the time. Are you
certain this is the exact cause of death?
From the stack trace (unless you've filtered it) it appears your code is
complete, and the response is committed, and that Tomcat is now forwarding
back through JK to Apache. So, I'm not sure your application can catch it.
I.e., you've got no code on the stack which could even have a catch { ... }

Or am I missing something?

So I searched all the servers HIGH and LOW for these files and only came across the Test server having them too.. So I put the modified copies on the Test server and the production server yesterday, now they are back to the original copies again.. BIGH SIGH I have looked through all the scheduled tasks and not found anything, my thought is it could be embedded somewhere in the Jave??

RE: ordering apps startups
This one has been addressed several times before. The short answer is NO. Tomcat being multithreaded does not guarantee order of start or access of a page. It would be better to change your apps so that they are not dependent on each other's state or order of starting. Think more in terms of event driven application development rather than developing a single user GUI. Robert S.

Is it possible to order apps startups. For example. I have app1, app2 and app3. I need that app3 starts up first of all. and app2 in second and so on. Is it possible ? Thanks in advance.
