Re: trouble with servelts
You are missing the servlet.jar file, which contains the neccesary
classes for your servlet to compile.
Just make sure your compiler can find the jar file in your classpath. If
you have a IDE like netbeans
than you have it easy, just mount the jar file, and you will be able to
compile without problems.

Re: trouble with servelts
Hello Girish,
You have to set the CLASSPATH environment varaible to include the tomcat
install directory\common\lib\servlet.jar in order to compile servlets. Have
you run the example application available at
http://localhost/examples/servlets/index.html.

migrating from TDK2.1 to tomcat 4.1.29
hi, i wanted to get an app developped under TDK2.1 to run under tomcat 4.0( running as a service!). I couldn't find tomcat 4.0 so i had to get 4.1.29, installed it then tryed to copy everything from tdk2.1\webapps\myapp_name\WEB-INF\ to tomcat4.1.29\webapps\myapp_name. It didn't work, because of the screens that were not placed in the proper location. Now i would like to know where i have to copy the screens that can be found under tdk2.1\webapps\myapp_nametemplates\app in the newly installed tomcat?? My second question relates to the actual webserver running under the TDK. When i installed the TDK bundle, there was a webserver listning on port If i got it right, i can use the TDK as a webserver itself, i wouldn't need to installed a third party webs8080, so i understood that i wouldn't need another webserver.

ClassCastException
Hi I am using axis web services with the java cog kit, each web service is a application under tomcat. But when two applications wish to use the cog kit, ie the web service is invoked, the first web service works fine and the the second throws this stackTrace: java.lang.ClassCastException at org.globus.gsi.bc.BouncyCastleUtil.getIdentity(BouncyCastleUtil.java:387) at org.globus.gsi.bc.BouncyCastleUtil.getIdentity(BouncyCastleUtil.java:402) at org.globus.gsi.GlobusCredential.getIdentity(GlobusCredential.java:342) at org.globus.gsi.gssapi.GlobusGSSCredentialImpl.lt;initgt;(GlobusGSSCredenti alImpl.java:56) Now if i restart tomcat, and call the second web service first, it works fine, but then the original first web service when called throws the exception. It seems that two applications cannot load the cog kit under tomcat?

Session expires on accessing load balanced servers individually
Hello, On accessing an individual servers among five load balanced servers, I get session expired error for my web based application. For ex: I have 5 servers as a1, a2, a3, a4, a5 So when I access the URL a1.appname.com, on accessing the web application, I get session expired message. This happens on few of the systems and not on all. Does this problem relates to tomcat / apache settings or can we do something for it through Internet Explorer settings.

[offtopic] Architecture Question
Hi, We have two tomcat servers. One is located at our enterprise. The other is located at our hosting provider. They can see each other by Internet. We would like to set up an unique authentification system for both server. The authentification system will be on the server at our entreprise. The web applications on both servers will query the authentification system. What's the best/clean/nice way to do this ? JAAS ? Web services ? SSL keys ? Thanks
Re: TC 4 -oreillyMultipart- TC5
Hi Joav,
the hint putting the lib into WEB-INF/lib instead of
$CATALINA_HOME/common/lib
put it, thanks to you.
But why ? Another classloader issue ? I think this could only be a
workaround, not really a solution
because this public lib may be used by other servlets, too.
What worries is that not all of the classes inside the lib were rejected but
only one of them.
Is there a kind of class-version-control ? Strange...
Hope this gets fixed in the upcoming non-beta release of TC 5.

Yes, it locates the connection details (i.e., the JDBC connection method, the database name, user and password) somewhere centrally so that I don't have to keep coding it, but all of the connection overhead still has to be dealt with in every servlet in a webapp. The datasource solution that a few people in the list (including me :) ) have been asking you to look at provides a connection pool to your web application. In your code where you ask for a connection from JNDI, you are actually getting a connection from the pool, which is already setup. When you call the close() method of this connection, it is not actually destoryed but returned to the connection pool, ready to be used. I'm sorry. When I said connection overhead, I didn't mean the overhead of creating a Connection object, I meant the overhead of having to write all the code to create one. I understand that there's a connection pool in a central location, but getting a connection from that pool is no less complicated for the programmer than creating one from scratch. I'm incredibly lazy. It seems that if I'm only going to be connecting to two or three databases in a webapp, it should be possible to maintain open connections to those databases somewhere so that anywhere in my webapp I can issue a statement that runs a SQL statement. In other words, I want to encapsulate the connection creation so that my other programs can just assume that it's done. This may not be possible, but it seems a reasonable OO thing to do. Does that make more sense, or am I still just confused? Todd - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

The sessionCreated() method is called when the session is first created,
and
therefore has no attributes set.
If you are interested in session attributes, perhaps you should look at
HttpSessionAttributeListener or HttpSessionBindingListener.
Hope this helps

Sorry, just joined this group - so I hope I am not jumping in at the wrong
time to this thread.
I am running Tomcat 4.1.18 (with Cocoon on Windows 2000, incidentally)
Anyway, I have implemented a HttpSessionListener, code below is for the on
sessionCreated event handler
I am interested in various session attributes, and I am confused as to why
I
can only access the session id and not any attributes. I have propogated
attributes to the session (I am able to access them in Cocoon). Output from
Tomcat as follows :
User null
Session E0647E125B965537D1B7E087F5915FA2
Driver loaded OK
Acquired connection OK
Executed OK - login
public void sessionCreated(HttpSessionEvent se)
{
Object sessionId = se.getSession().getId();
Object sessionUser = se.getSession().getAttribute(user);
System.out.println(User +sessionUser);
System.out.println(Session +sessionId);
for (Enumeration e = se.getSession().getAttributeNames() ;
e.hasMoreElements() ;) {
System.out.println(Attribute +e.nextElement());
}
try
{
Class.forName(dbDriver);
System.out.println(Driver loaded OK);
con = DriverManager.getConnection(dbURL,dbUser, dbPwd);
System.out.println(Acquired connection OK);
Statement s = con.createStatement();
rs = s.executeQuery(update calib_users set logged_in = 'Y' where
username = 'simon');
rs = s.executeQuery(commit);
System.out.println(Executed OK - login);
}
catch (ClassNotFoundException cnfe)
{
System.out.println(No driver);
return;
}
catch (SQLException sqle)
{
System.out.println(No connection);

Re: Servlets with JDBC connectivity
I hadn't noticed that ResultSets need to be closed. But why couldn't I close it after dealing with it in whichever servlet I call it from? Also, if the Connection is a static variable in SQLUtils that all the servlets use, it won't ever get closed. I'm just realizing that there's probably a major scalability issue here that I need to worry about, but I'm still thinking this has to be easier... Todd P.S. A little context, so you all don't tell me to get another job. I teach high school math and computer science, and in one of my advanced classes we decided to create a webapp. One group is working on the database backend and another group is writing Velocity templates to display the information. I'm learning as we go, because I've written about 5 or 6 total servlets since last summer. I've got the Java Servlets book and the JDBC book from O'Reilly, but I haven't had time to read them cover to cover, so there may be gaps in my knowledge. All my database knowledge has also been picked up since last summer, and I spend maybe an hour a day actually writing code. My concern is that we set this up in a way that is sound, but perhaps more importantly, clean and easy to understand. Since it's me and a bunch of high school seniors who'll be messing up the code, something straightforward seems the way to go. Thanks again for your patience. On Dec 3, 2003, at 12:27 PM, Christopher Schultz wrote: Todd, SQLUtils.executeQuery(a SQL statement); SQLUtils.executeUpdate(another one); Just out of curiosity, what do these methods return? If the former returns a ResultSet object, then you're in for a world of trouble. The ResultSet will never get closed, or you'll close the connection over which the ResultSet communicates, and then you're hosed, 'cause the calling code can't access the data. -chris - 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]

Max. wait time for a Servlet Response
Hi, How long a servlet can wait to give reponse. Actually, my servlet wants to wait until some process done by other component.

Tomcat's ThreadPool and InheritableThreadLocal variables
Hi, A query regarding InheritableThreadLocal variables in the tomcat context. To explain the problem i am facing: If i am correct,for each request,tomcat uses a thread from it's threadpool to process the request. Suppose during one of these requests,i set the value of a InheritableThreadLocal variable.Once this request is processed,the thread will be available for use from the ThreadPool.Does tomcat reset the value of the InheritableThreadLocal variable which was set by the previous request processing?(it should,ideally). The tomcat version i am using is 3.3.1a.Also use the struts framework model. It seems to me that the InheritableThreadLocal value which was set by a previous request on a thread is still retained when that thread is reused for processing another request.Are there any known issues regarding this? Would be really helpful if someone can answer this.A bit urgent.Thanks in advance. Regards, Umapathy - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: servlet sendRedirect() to j_security_check problem (remember me)
That's a fairly circuitous route for a login. I guess you do what you have to do though. I was wondering whether I could adapt it to allow an SSL login form to be used to login to non-SSL pages, but I think the httpClient would leave the j_security_check post in plain text on the net - unless it never leaves the server, but I'm not sure that would be possible.

How to measue performance? Log4j on/off.
We have a performance issue with a web page being served via Tomcat/Apache. I don't think it has anything to do with Tomcat, but I am being asked to turn debug logging off to help improve it. I'm resisting because the output has been extremely valuable in solving problems that still crop up and to find out what the users are really doing as opposed to what they said they did.

Re: TC 4 -oreillyMultipart- TC5: Corrupt form data: premature ending
Another issue came up comparing TC4 and TC5:
using the oreilly multipart lib on TC5 causes the error
...Corrupt form data: premature ending on POST uploads.
As stated in the FAQ's at http://www.servlets.com/cos/faq.html
this problem is merely due to the webcontainer and has been fixed with
Tomcat 4.
I tested and can state that this problem doesn't occur with TC4.
But it is apparent with TC5 again.
Will this be fixed ?

Howdy,
I would use JMeter first, if you're just looking for performance
numbers, i.e. time to serve that page. JMeter is ideally suited for
that. JProbe and OptimizeIt are great, but they do more than you need
in this case and they WILL skew performance significantly.

I suspect I am missing something (possibly a great many things) and would appreciate any insight anyone could provide. I've not been able to find a single source that addresses this problem although I've found bits and pieces in several places. I have a simple servlet running in Tomcat that does nothing more than report back that it is alive. Posting to it at http://myserver:8080/simpleServlet/simpleServlet returns a response of: simpleServletResponseI am alive!/simpleServletResponse. Additionally I have a simple client app that calls the servlet with a POST. The client can run on either the same machine as the server or a different machine. 1. Using an HttpURLConnection in the client app works fine. I can call the servlet on either port 8080 (http) or 8443 (https). This works from either machine. 2. If I do nothing other than change the HttpURLConnection to an HttpsURLConnection then everything falls apart immediately and I don't understand why (I do believe I have the proper imports included and it all compiles fine). From everything I can tell I should be able to replace the one with the other. 3. Keystores certificates: I have generated certificates for both machines using keytool and have imported the client machine certificate into the trustedcerts file on the server machine. I have NOT had any of these certificates signed by a certificate authority (and due to complexities I won't go into here that isn't likely to happen). Do the certificates need to be signed by a CA in order for HttpsURLConnection to work? 4. The result of calling the method url.openConnection() is that null is printed to the screen then program execution simply stops. No Exception seems to be thrown - everything just stops. Why? HttpsURLConnection conn = (HttpsURLConnection) myurl.openConnection(); Ultimately I would like to get Client-Certification working but haven't been able to find a good guide out there for doing so.

If you declare a constant boolean variable as false and use it in your branch

Showing my C heritage here, but can't you do something like
Log(an error has occurred);
And in Log have a directive like
class Logger()
{
void Log(string msg)
{
#ifdef DEBUG
... log message ..
#endif
};
And so you can compile a version with debug or no debug. Those if()
statements are still going to take time to process, even if there is no
logging going on.

Re: How to measue performance? Log4j on/off.
Hi, Yoav,
I'll take a look at thos products. I wasn't aware of your other
suggestion. I assume you mean it will improve the performance when
debugging is turned off thus preventing the debug statement from being
called at all. Is this because there is a lot of overhead with
debug(...) calls even with debugging off?
This will be fun, I've got a LOT of debug calls to change. 8(
Thanks,
Jim.

I would use JMeter first, if you're just looking for performance
numbers, i.e. time to serve that page. JMeter is ideally suited for
that. JProbe and OptimizeIt are great, but they do more than you need
in this case and they WILL skew performance significantly.
As an aside, make sure you have all log4j Logger#debug statements
enclosed in if(logger.isDebugEnabled()) { ... } clauses -- that's an
order of magnitude or so runtime performance improvement.

if you have any money to spend, it would be worth running a code

Subject: How to measue performance? Log4j on/off.
We have a performance issue with a web page being served via
Tomcat/Apache. I don't think it has anything to do with Tomcat, but I
am being asked to turn debug logging off to help improve it. I'm
resisting because the output has been extremely valuable in solving
problems that still crop up and to find out what the users are really
doing as opposed to what they said they did.
That said, is there a definitive way I can compare the performance of
the site before and after turning the logging off? Other than a
stopwatch?
Thanks,
Jim.

Howdy, Why don't you just test it if it's so urgent instead of waiting for a reply from us? ;) I think the variables will stay with the thread, as they're not bound to the lifetime of the request.

Howdy,
Another issue came up comparing TC4 and TC5:
using the oreilly multipart lib on TC5 causes the error
...Corrupt form data: premature ending on POST uploads.
As stated in the FAQ's at http://www.servlets.com/cos/faq.html
this problem is merely due to the webcontainer and has been fixed with
Tomcat 4.
Umm, you misread that section of the FAQ. It states that there are many
possible causes for this bug. A small subcase (IE, client hitting stop
then starting again, leading to empty input stream) was isolated and
fixed in a couple of containers (tomcat 4.0 and weblogic 6.1 according
to the FAQ).
I tested and can state that this problem doesn't occur with TC4.
But it is apparent with TC5 again.
Will this be fixed ?
If you provide a concise description along with a test case or steps to
reproduce your problems, there's a chance it might be fixed.
There has been enough testing for uploading (with the standalone
connector, at least, but there's no difference with JK for this), that I
can confidently say that there's very little likelihood of a Tomcat bug
in this area.
Maybe if the thing uses readLine on the Tomcat provided reader (a rather
annoying method to implement, so maybe there could be a bug), but in the
unlikely case it does, I recommend dumping that library in favor of
commons-fileupload (readLine is by definition awful performance wise).

RE: How to measue performance? Log4j on/off.
Howdy, I would expect that the Appenders and Formatters only come into play if debug is enabled. Am I wrong ? You're right in principle, but the definition of debug is enabled is not always trivial: a class may have multiple loggers (and in log4j 1.3, multiple loggers in multiple logging domains) with different levels set up, so one may be debug-enabled while another isn't. There are also other more advanced log4j usage cases which increase the complexity of the debug call. But this is getting off-topic: the basic point was that the isDebugEnabled() check is a good practice, can only improve performance (at runtime, without changing code or using pre-processors), and can help the original poster.

I've actually improved the Remember Me feature a fair amount since I posted to the Tomcat User list. The sendRedirect works, however, it (in some browsers) puts the URL (with password) into the address bar. This isn't a big deal IMO since it's the user that just logged in and they don't mind seeing their own passwords. However, the URL tends to show up in server log files which can be a security hole. Because of this, I changed to using an HTTP Post with Jakarta Common's HttpClient. I also moved my form-login-page and form-error-page into a security folder and then set my cookies for the /appname/security path rather than / - this makes it so the user/pass cookies are more secure and can only be retrieved when logging in, rather than for any URL in the site.

RE: How to measue performance? Log4j on/off.
there are two things to consider: - the time that is spent in arguments of the call. - the time that is spent in the call If you have something like debug(abc) there is hardly any time spent constructing the argument. But if you have debug(abc + someNestedObject.toString()); or debug(translate(abc)); (or something like that) You pay the time spent in translate() and toString() even if debug is off. (They are evaluated before the method is called) Depending on the nature of the called methods that can be quite some time. In opposition to Mr. Shapira I wouldn't expect that log4 spends much time in the call to debug() as I would expect the 'if (logger.isDebugEnabled)' as first test inside of debug().

Re: TC 4 -oreillyMultipart- TC5: Corrupt form data: premature ending
Rémy,
I'm quite sure. With a summary of oreilly´s sources I see:
class MultipartParser {
...
private ServletInputStream in;
private byte[] buf = new byte[8 * 1024];
...
ServletInputStream in = req.getInputStream();
...
do {
String line = readLine();
if (line == null) {
throw new IOException(Corrupt form data: premature ending);
thrown when using TC5, but not on TC4
}
...
private String readLine() throws IOException {
int result;
StringBuffer sbuf = new StringBuffer();
do {
result = in.readLine(buf , 0, buf.length);
...
sbuf.append(new String(buf, 0, result, encoding));
}
...
return sbuf.toString();
}
}
looks quite normal, doesn't it ?

There's a ServletIS.readLine(byte[] b, int off, int len) method, but no
readLine returning a String (that's in the BufferedReader).
SevletIS.readLine is not optimal already (I thought nobody would use
it). Maybe it would be a good idea to attempt to reimplement it
eventually.

re: compiling tomcat-5.0.16 from source
Hello, I am curious how I compile all the components of tomcat from source code. I am having various problems, the only one that made sense was that I had to upgrade mail.jar.

RE: How to measue performance? Log4j on/off.
Howdy,
This is off-topic now, but the short answer is no. The longer answer is
that java doesn't have such constructs at runtime, and we are talking
about runtime not recompiling the code. The even longer answer has to
do with log4j architecture and Logger#debug being a potentially very
expensive call depending on its parameters and configured appenders,
whereas isDebugEnabled is an optimize hash lookup.

Showing my C heritage here, but can't you do something like
Log(an error has occurred);
And in Log have a directive like

And so you can compile a version with debug or no debug. Those if()

RE: How to measue performance? Log4j on/off.
Howdy,
The whole point was to change at runtime without recompiling. This is
what lgo4j allows you to do.
As to my order of magnitude improvement by using
if(logger.isDebugEnabled()) -- it's well-proven and benchmarked in the
log4j documentation, and the log4j kit comes with the benchmarks you can
run yourself.
Finally, even the example with debug(x) vs. debug(translate(x))
missed something -- the possibly complex configuration of log4j. If,
for example, you have an appender such as JMS, Telnet, or SMTP (all come
with log4j) configured to send out debug messages, every call to debug
can be much much more expensive than simply writing a text string to a
file.

There is a hack to accomplish similar results.
If you declare a constant boolean variable as false and use it in your

static final boolean DEBUG = false;
if(DEBUG){
//conditional code goes here

I would expect that the Appenders and Formatters only come into play if debug is enabled. Am I wrong ? -Original Message- From: Shapira, Yoav [mailto:[EMAIL PROTECTED] Sent: Thursday, December 04, 2003 3:34 PM To: Tomcat Users List Subject: RE: How to measue performance? Log4j on/off. Finally, even the example with debug(x) vs. debug(translate(x)) missed something -- the possibly complex configuration of log4j. If, for example, you have an appender such as JMS, Telnet, or SMTP (all come with log4j) configured to send out debug messages, every call to debug can be much much more expensive than simply writing a text string to a file. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

If they're doing *that*, they might as well use the buffered reader

Byte by byte input works (it's inefficent, obviously, but it works).
I recommend adding some debug in their readLine method to see what is

RE: anyone running tomcat-4.1.29 with commons-daemons?
Howdy, It's commons-daemon (not daemons) ;) To run it with 4.1.29 you need to right some code. Tomcat 5 has an implementation of the DaemonContext, you'd need to do something similar for tomcat 4. It's possible. In fact I believe a solution with more details was discussed within the past two months on this list: search the archives.

Upgrade from 4.1.29 to 5.0.16, logging is too verbose?
I was running tomcat 4.1.29 with a log4j jar in the $CATALINA_HOME/common/lib folder and a log4j.properties file in $CATALINA_HOME/common/classes folder. This worked fine, and kept the log messages at the level I wanted them. When I installed 5.0.16, I put the log4j jar and properties file in the same locations listed above, but now when tomcat starts, it spits out a ton of INFO: messages into catalina.out, so I don't think it is actually using the log4j configuration.
