RE: UTF-8 problems
Hi In Java 1.3, the default encoding is set to ISO-8859-1 which includes all the Country(German) special characters In Java 1.4, the default encoding is set to ASCII which converts all German special characters to '?' The fix for this problem was just setting an environment variable CATALINA_OPTS=-Dfile.encoding=ISO-8859-1 -Original Message- From: Tang Guangyu [mailto:[EMAIL PROTECTED] Sent: Monday, August 04, 2003 5:30 AM To: Tomcat Users List Subject: Re: UTF-8 problems This problem was caused by your browser. The browser will use its own encoding to encode form values post back. You need set proper encoding to request - request.setEncoding(BROWSER_ENCODING). Or you can write a filter to simplify your work. - Original Message - From: Nathan Coast [EMAIL PROTECTED] To: tomcat user [EMAIL PROTECTED] Sent: Sunday, August 03, 2003 9:11 PM Subject: UTF-8 problems Hi, I have an text fields in a form that will contain UTF-8 characters e.g. ''. I can retrieve utf-8 chars from the db and display them correctly in jsps via tomcat. The only problem comes with submiting forms to tomcat. request.getParameter() returns the incorrect value for the char e.g. '' instead of ''. AFAIK the default encoding of java is UTF-8 so I'm not to sure where to look.

Pedro, unjar-ed classes go under WEB-INF/classes/{SOME PACKAGENAME},
jar files
go under WEB-INF/lib
Your java beans will never be found if they just reside under WEB-INF .

Re: Configuration Error?
The bean should be in the Tomcat/ROOT/WEB-INF/classes/mybeans directory not Tomcat/ROOT/WEB-INF/mybeans. Classes underneath web-inf is the directory for classes. Also, perhaps try removing the contentType directive at the top of the page as it is unnecessary. Oh and also you have put id=bean= - remove the = from the bean=, then change that to 0 as referenced later on. cheers Pete Kiss Technologies http://www.kisstechnologies.co.uk/ 4, Percy Street London W1T 1DF Phone numbers: Phone 020 7692 9922 Fax 020 7692 9923 Pedro Silva [EMAIL PROTECTED] 03/08/2003 20:11 Please respond to Tomcat Users List To: [EMAIL PROTECTED] cc: Subject:Configuration Error?

JSP seems to be executing twice and we are getting duplicate records in our database
Hi folks, We have a weird problem where a JSP seems to be executing twice and we are getting duplicate records in our database. The data is coming from a HTML form and upon submit a subsequent JSP page is called that performs the SQL insert, etc. We are also getting duplicate log messages so our initial conclusion is that it's a Tomcat related issue. We have tested this with Tomcat 3.3.1, J2SE 1.3.1 and from the client side using both IE 5.5 and 6.0 and it happens intermittently. At this stage we have absolutely no idea of what is going on. Alas I didn't write the code so I'm not up to speed with its structure, flow or functionality. I've searched the list archive and there appears to be several references to similar problems. However I am unable to find any real answer to what might be causing this problem. Hoping someone out yonder can help.

RE: JSP seems to be executing twice and we are getting duplicate records in our database
Adrian, If you do not want anothe rows created every time the page is submitted, then you are going to have to implement something to stop this. TOMCAT will not do this for you. Without knowing the requirements for the form, stopping multiple rows being generated could be as simple as: - Assign a session to the user (clients browser). - When the form is submitted, capture the sessionId in the database with the record. - If there is no row with the sessionId in the database, create a new record with an insert. If there is a existing session, use an update to modify the record.

Servere performance reduction upon upgrade
Hi, this being my first post I regret if any formalities are offended. I have just upgraded from Tomcat 4.0.3 and jdk1.4.0 to Tomcat 4.1.27 (tried 5.0.5 as well) and jdk1.4.2 on a Windows NT machine. Previously I used the isapi_redirect.dll to redirect request from IIS but has now installed the JK2 (isapi_redirector2.dll). The requests are still succesfully being redirected by IIS but are a factor 10+ slower than before the upgrade. When requesting Tomcat directly through port 8080 things are as blazing as always. As both installations are out-of-the-box following the guidelines and How-To documents I have no clue of what might be wrong?

RE: JSP seems to be executing twice and we are getting duplicaterecords in our database
Hi Bill, Would I be right in assuming that you're inferring a user is submitting the form multiple times by clicking the submit button/link more than once? Or are you perhaps suggesting the browser is sending multiple requests without user intervention to the server hence the reason why the responding JSP is processing duplicate requests to insert the data twice? I understand your suggestions and points. I don't however understand why the problem is occuring as in our case the additional execution of the JSP doesn't appear to be initiated by the user -- i.e. multiple clicks on a submit button, etc. I've triggered the submit using keyboard control which should initiate only one instance of the form data being sent to the server and the problem still occurs. It also seems a bit kludgy to first determine if a session ID associated with a specific record already exists prior to inserting a new row.

RE: Configuration Error?
Howdy, But do I have to import my own classes? If so what is the purpose of having the Bean code separated from the JSP code? Yes, you have to import your classes so the JVM knows what classes you're using. The point of separation is two-fold (probably more): - Other components can use the Bean separately without knowing anything about your JSP page - The bean and the JSP can be developed (and packaged/deployed) independently, as long as the interfaces are well-defined.

RE: Re[2]: Servlets JSPs log to different files
Howdy, I would point out a couple of things, since you posted this code as an example, but they are subjective. I have a servlet that is loaded at the time tomcat starts. The container is free to destroy and reload this servlet as it deems necessary. Accordingly, use a ServletContextListener instead. DOMConfigurator domConfig; Should be private? And inside the method rather than a servlet instance variable? then in the class (bean) that has no idea about the context i have the following: protected org.apache.log4j.Logger logWriter = org.apache.log4j.Logger.getLogger(nameoffiletoappearinlog); Why is this protected?

RE: Servlets JSPs log to different files
Howdy, Can anyone expand on this further and explain how to use a Log4j logger reference in beans that do not have a notion of what the underlying servlet context is? The only way I can see how to get this to work is to pass the logger reference as an argument in the bean's constructor. You initialize the log4j system somewhere, e.g. a servlet context listener's contextInitialized() method. Then in your classes you just have a Logger member variable: private static final Logger LOGGER = Logger.getLogger(MyClass.class.getName()); And you use this logger as you want. It's typical to name the logger the same as the class, but not required. All of this is in the log4j docs. The classes don't need to know how log4j is configured, and they definitely don't get a Logger passed to them (unless you're doing some very strange things).

Jasper, JSPC, Ant and Precompiling JSP's
Hello,
I've done my best to review the archives to resolve my problem, but I've
not found a solution there so I'm posting it.
I'm stuck back on Tomcat 4.1.24 (LE) and I'm encountering some issues
with JSP Precompilation using Ant and JSPC. First let me outline my problem.
Most messages I've read to date focus on using JSP recompiling to turn
the JSP into Servlets stored in a WAR file and require generating a
fragment web.xml file and including it into your web.xml, I AM NOT
trying to do this. I want my JSP's to get precompiled into the work
directory of Tomcat and used from there, the exact same way that Tomcat
does it. This way afterward, if the jsp is modified, tomcat can still
recompile it.
I have the following jspc and javac tasks coded in my build.xml:
mkdir dir=/var/tomcat4/work/Standalone/localhost/Foo/
jspc srcdir=${deploy.home}
destdir=/var/tomcat4/work/Standalone/localhost/Foo
failonerror=false
compiler=jasper41
classpath
!-- snip --
/classpath
exclude name=**/WEB-INF/**/
/jspc
javac destdir=/var/tomcat4/work/Standalone/localhost/Foo
optimize=off
debug=on failonerror=false
srcdir=/var/tomcat4/work/Standalone/localhost/Foo
excludes=**/*.smap
classpath
!-- snip --
/classpath
/javac
Both tasks get completed successfully. I observe problems in the package
names of the JSPC generated java files where the following is the case.
/var/tomcat/webapps/Foo/Bar/Bam.jsp results in the package name
package Bar;
...
which becomes a problem when I try to access this JSP included into
another, I get the following error
java.lang.NoClassDefFoundError: org/apache/jsp/Bam_jsp (wrong name:
Bar/Bam_jsp)
at java.lang.ClassLoader.defineClass0(Native Method)
at java.lang.ClassLoader.defineClass(ClassLoader.java:502)

at org.apache.jasper.servlet.JspServletWrapper.getServlet(Unknown Source)
at org.apache.jasper.compiler.Compiler.isOutDated(Unknown Source)
at org.apache.jasper.compiler.Compiler.isOutDated(Unknown Source)
...
I read somewhere that work had been done on my version (4.1.24) to
eliminate a naming conflict problem. I assume this is why there are now
package names on my _jsp.java files. I find that when I let
Tomcat/Jasper compile all my jsp's the java files *all* have the package
name org.apache.jsp no matter what their directory. I assume that my
compilation is conflicting with Tomcats because of the package naming
differences.
So, I've tried adding the following attribute package=org.apache.jsp
to the jspc task, but this results in even more problems because all the
package names now look like:
package org.apache.jsp.Bar;
and when they are compiled, they end up in a separate directory
/var/tomcat4/work/Foo/org/apache/jsp/Bar/Bam_jsp.java
Any ideas or solutions out there would be really helpful for me. I just
want to have Tomcat start out using my precompiled jsp's instead of
initially compiling them itself.

RES: Cookie problem max age problem - Best practice to solve it
Sorry Steve, one information isnt right!

After this process is completed ok, a cookie is created. So, when the user asks for logout, the plugin tries to delete the cookie, probably setting 0 to max age. If i work with OC4J, this steps runs fine and the user becomes abled to make another login request on the same browser instance, without needing to close it. But, if i work with TomCat, i need to close the browser instance and open another one to be sucessful. Needing help still. Regards, Euclides. This does not change any of the previous discussion. The problem hinges on the answers to two questions: What are the values used for domain, path, and name when the cookie is set? What are the values used for domain, path, and name when the cookie is deleted? If you can demonstrate that the same set of values are used in both cases, then this sounds like it would be a tomcat problem. You can examine the Set-Cookie headers sent by the server to see whether this is the case. Otherwise, this is an issue that should be raised with the vendor who provided the authentication plugin. -- Steve - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
how to run web application in different modes like test, production
Hi all, I have a web application that runs -depending on the content of a property file - in different modes. But the application can only run in either one of these modes at a time.

What kind of information would you like to receive about it? Does Session object work different between OC4J and TomCat? Then you're in trouble. Session objects live within the memory of the JVM process where the servlet container is running. You aren't going to be able to share them between two different processes. Even within a single container, there are still limitations on sharing Session data; you can't share from one context to another.

Re: Tomcat 4.1x running as NT Service Issue
I told you wrong about how to set the memory limits when running as a
service. You can set the memory options in the Windows registry using
regedit.
In regedit, open HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\Apache
Tomcat 4.1\Parameters
Add a string value named: JVM Option Number 3 and set it's value to -Xms100m
Add a string value named: JVM Option Number 4 and set it's value to -Xmx100m
Change the JVM Option Count to 5 (was 3 at least on my machine. The value of
this field must match the number of JVM Option Number x values).
You can also write log statements to check allocated and available memory.
Following is an example thread that we used. I've cut out a few parts that
are specific to our application and the formatting is screwed up from
cutting and pasting it, but should be close enough to get you going.
public class MemoryMonitor implements Runnable {
private boolean done = false;
private Runtime rt = Runtime.getRuntime();
public MemoryMonitor() {
Thread theThread = new Thread(this);
theThread.setDaemon(true);
theThread.setPriority(Thread.MIN_PRIORITY);
theThread.start();
}
public void run() {
while (!done) {
try {
long freeMemory = rt.freeMemory()/1024;
long totalMemory = rt.totalMemory()/1024;
long memoryUsed = (totalMemory-freeMemory)/1024;
long allocatedMemory = (totalMemory/1024);
AppLog.info([Memory Monitor] -- +new
Timestamp(System.currentTimeMillis()).toString()+ --- Memory Allocated:
+(int)allocatedMemory+k);
AppLog.info([Memory Monitor] -- +new
Timestamp(System.currentTimeMillis()).toString()+ --- Memory Used:
+(int)memoryUsed+k);
rt.gc();
if(allocatedMemorytotalMemory){
}
Thread.sleep(
MemoryMonitorProperties.getInstance().getCheckMemoryInterval());

I am not sure why we are not running 1.4, but the image from corporate has

I'm not sure that this is it, but you might try setting the JVM min and max
memory limits when starting Tomcat by adding the following to
$CATALINA_HOME\bin\catalina.bat:
set JAVA_OPS = -Xms100m -Xmx100m
Default for the JVM I believe should be 64mb, but who knows.
Why are you using jdk 1.3.1? Do you have existing code that is not
compatible with jdk 1.4? We are running Tomcat 4.1.24 as a service under

Subject: Tomcat 4.1x running as NT Service Issue
I have scanned all the archives, and have seen some issues that are similar
but not quite the same so I am posting this request.
We are running Tomcat 4.1.24 Binary release, as a Service on Windows 2000
SP3 and SP4 Pro version. No JSP just servlets. The Tomcat instance is
hosting 2 servlets that talk to a local SQL Server 2000 database on the same
machine. A VB 6 client is talking to the servlets via http post etc, and
exchanging XML documents for requests and replies.
Running as a Service, with JDK 1.3.1 as the JVM the service will crash after
about 10 minutes of activity. Just prior to the crash, available memory will
decrease to 0 and the system will slow to a crawl with a lot of disk
activity, paging I imagine.
Running Tomcat in a window alleviates the problem entirely, so I am assuming
there are some parameters that are being passed via the Startup.bat file
that are not happening with the service. Or perhaps to the JVM, I am very
new to Tomcat so I am not sure how to accomplish this. However we really
want to have Tomcat running as a service since this is a laptop app being
deployed to hundreds of our users, and we don't want them mucking about with
the Window created by running Tomcat as a windowed service.
Plus, having it run as a service means it is one less thing to worry about
in our application
Some questions
Hello, In our company, we are using Tomcat Version 4.0.1 and Java 2 SDK, Standard Edition Version 1.4.0 a. I read that if one uses 'catalina nonaming start' instead of 'startup', it would help disable the use of JNDI within Tomcat. (1) Is this feature available with Tomcat 4.0.1 ? (2) Does it mean that JNDI is enabled by default ? (3) Can it be disabled thro' say server.xml ? b. I also read that one can set up CATALINA_OPTS=-Xmx44M (1) Will this set the max memory size of 44 MB ? (2) Again, is this feature available with Tomcat 4.0.1 c. I read on the net that one can set the -server option in JDK 1.4... (1) Where does one setup this option? Is it in catalina.bat and how? Awaiting your reply.

Why integrate Tomcat with a web server?
I have a question for John Turner about a statement in the book Apache Tomcat Security. Page 12 says: As discussed earlier, running publicly available web services as root or superuser is typically a bad idea, so the solution is to avoid using Tomcat as a stand-alone web server on port 80 by integrating it with a standard HTTP web server such as Apache, Microsoft's IIS, or Sun Microsystem's iPlanet. Question: Does this apply when running under Windows? The reference to as discussed earlier talks about running Tomcat as a service with more permissions than necessary. Windows defaults to running services as SYSTEM which has administrator privileges. Fine, but as also mentioned earlier, you can create a user account with less permissions and setup the service to run Tomcat under that account. So, how does the statement on page 12 relate to running Tomcat under windows, i.e. why run Tomcat with IIS rather than just run Tomcat? There may be performance reasons, but from a security point of view, is there increased security risks in running Tomcat without IIS when running as a service under Windows? Nathan
RE: Some questions
Howdy, In our company, we are using Tomcat Version 4.0.1 and Java 2 SDK, Standard Edition Version 1.4.0 If possible, update to 4.1.27 and JDK 1.4.2. a. I read that if one uses 'catalina nonaming start' instead of 'startup', it would help disable the use of JNDI within Tomcat. (1) Is this feature available with Tomcat 4.0.1 ? (2) Does it mean that JNDI is enabled by default ? (3) Can it be disabled thro' say server.xml ? Where did you read this? Looking at $CATALINA_HOME/bin/catalina.sh would tell you this option is not available. Reading the servlet spec will tell you that a container is required to support naming. So yes, JNDI is available and enabled by default. You can't disable JNDI support per se, but you can make sure no JNDI resources are defined in server.xml, so that any JNDI lookups return null. b. I also read that one can set up CATALINA_OPTS=-Xmx44M (1) Will this set the max memory size of 44 MB ? (2) Again, is this feature available with Tomcat 4.0.1 Yes, this indicates to the JVM to allow up to 44MB on the heap. This option is available with tomcat 4.0.1, as once again simply looking at $CATALINA_HOME/bin/catalina.sh would show. c. I read on the net that one can set the -server option in JDK 1.4... (1) Where does one setup this option? Is it in catalina.bat and how? It's a JVM option just like the others, e.g. -Xmx above. It's available even before JDK 1.4.

I am running Tomcat 4.1.24 on Windows NT 4.0. When I get a runtime
error
in my servlet, I'm getting stack traces on the console instead of in
the

Several options:
-Add swallowOutput=true to your context definition, and the console
output will be redirected to your servlet context log, as if you had
used ServletContext#log(...).
- Use a StringWriter to get the stack trace, e.g. for Exception e,
StringWriter sw = new StringWriter();
PrintWriter pw = new PrintWriter(sw);
e.printStackTrace(pw);
pw.flush();
getServletContext().log(sw.toString());
- Use a logging system like log4j and just do
try {
...
} catch(Exception e) {
LOGGER.error(Messed up: , e);
}

JspC on the other had, treats the directory as a package hierarchy (which is great if your going to dump them into the classes directory and map them in your web.xml).

connection pooling - user vs. username
A question regarding Tomcat connection pooling - according to the JNDI Datasource HOW-TO, the parameter for username should be placed in the ResourceParams section thusly: parameter nameusername/name value/value /parameter But I've also seen this parameter also called just user. According to the docs, Resource parameters are defined by name, and the precise set of parameter names supported depend upon the resource manager (or object factory) you are using - they must match the names of settable JavaBeans properties on the corresponding factory class. This would seem to say that it makes a difference whether user or username is used, but I've seen working examples where either user or username is used, and the same object factory is used. Which is it? I tried looking at the API and didn't find an answer - anyone? Thanks! -- Lynn Hollerman. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Singleton and Reloadable Contexts.
Hello All!
Our team here has written a simple Connection Pool
class that is a singleton.
I've noticed that whenever Tomcat reloads my webapps
context (when I add a new class or something like
that), that it the next call to the Connection Pool
get instance method doesn't see the previous
singleton, and hence, it allocates a bunch of new
connections.
This would be fine, except that the old connections
are never closed (it seems that the Garbage Collector
doesn't eat them up) so I think that the old instance
of the singleton is still floating around in the JVM
somewhere.
This causes all the free sessions on the Database to
be eaten up, forcing a restart of tomcat. Once tomcat
is restarted, all the connections are closed out
(since the JVM terminated, I guess) and things are
fine again.
What do I need to do so that the old connections are
removed? This is on Tomcat 3.3.1a. Here is the
relevent code of the Singleton getInstance method:
public static synchronized ConnectionPool
getInstance(ConnectionPoolConstants c) throws
SQLException {
constants = c;
if (instance == null) {
// Determine which database url to connect
db_url = constants.getTestDBURL();
String line = ;
try {
Vector return_vec =
DelphiRuntime.execCommandWithOut(hostname);
Enumeration return_enum =
return_vec.elements();
while (return_enum.hasMoreElements())
{
line = (String)
return_enum.nextElement();
}
} catch (InterruptedException ire) {
} catch (IOException ioe) {
}
if
(line.equals(constants.getProductionServerHostname()))
{
db_url =
constants.getProductionDBURL();
}
instance = new ConnectionPool();
}
return instance;
}
Thanks for any insights!
Cheers!

Thanks. But if this is the case, the download documentation might need some updating. The documentation used to specify that if you have JDK 1.4.x you only needed the LE version. It said nothing about commons jar files. And now, I can't find anything anywhere that specifies which one you should get.

Re: Singleton and Reloadable Contexts.
A singleton is only a singleton to the classloader it lives in. A webapp is
loaded in its own classloader, so when it is start/stopped or reloaded - a
new classloader is made. And so is a brand new set of singletons.
The easy workaround is to create a ServletContextListener which listens for
the webapp to be stopped. At that time - your can free the pool.
But I don't recall if ServletContextListener is available in the 2.2 servletapi.

Faking ServletContextListener with Tomcat 3.3.1a? [Was: Singleton and Reloadable Contexts.]
After looking through the archives more (why is it
that you always find something after you've asked.) I
found this message:
http://mikal.org/interests/java/tomcat/archive/view?mesg=51529
That's exactly what I want to do. However the server
is running Tomcat 3.3.1a. Short of updating the
server, is there anyway to fake the
contextInitialized() and contextDestoryed() methods in
the Older Tomcat?
Cheers,

request/session handling
Hi, can anyone tell me what happens if a user requests a servlet which might take 5 seconds to complete the request, and the user starts hitting reload a number of times? (I know the typical programming answer is 'why?! why would the user do such a thing?' but I am afraid I'm gonna have to give a better answer than that). Will the already running requests be aborted, will they complete, which output from which completed request will make it back to the user? I am asking because it appears the servlet can handle two requests 'simultanously' from the same user, which means I have to synchronize on objects in this users session, even if there is only one user using the application. Hope anyone can help. greetz Hans - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: request/session handling
All requests will keep executing. The user should get the last result. Hitting reload forces the browser to drop its connection and open another one to the server I think. The server doesn't know the connection has gone AWOL until it tries to send data to the client. --Angus -Original Message- From: Hans Wichman [mailto:[EMAIL PROTECTED] Sent: Monday, August 04, 2003 2:42 PM To: [EMAIL PROTECTED] Subject: request/session handling Hi, can anyone tell me what happens if a user requests a servlet which might take 5 seconds to complete the request, and the user starts hitting reload a number of times?

Howdy,
Consider a container-independent approach instead: write an
HttpSessionListener that's also a ServletContextListener. Have it keep
a static list of HttpSession objects, adding the session to the list on
its creation and removing on its destruction. Then, have the
contextDestroyed method go through the list and invalidate all the
remaining sessions.
