It is also possible to get the DataSource from the hibernate configuration if you want to access the database directly (for performance reasons).

The point is that this would be difficult to do efficiently at request start and so tradeoffs were clearly made. This may not have been documented right at first (I know I got burned once), but the issue has always clearly been there. I'd suggest living with it or writing your own filter.

Re: RequestDumperValve screws UTF-8 parameter parsing
The first thing a servlet (or filter) should do is set the encoding before touching the request parameters. Its not intended to be called somewhere late in the processing lifecycle. Since a Valve executes before any javax.servlet code - all bets are off (for the request encoding) based on the warning messages in the Valve. For GET requests, reparsing might work when a new encoding is requested. But for POST requests - doing so would require saving the entire POST body somewhere. This can easily cause a memory based DOS attack. -Tim Oded Arbel wrote: Then why is it at all possible to set the encoding ? it should not be needed and there for should not be possible.

RE: Error loop for R - Tomcat 3.3.1a
Sid,
The code where the exception is occurring is:
private final String getAbsolutePathRelativeToContext(String
relativeUrlPath) {
String path = relativeUrlPath;
if (!path.startsWith(/)) {
String uri = (String)
request.getAttribute(javax.servlet.include.servlet_path);
if (uri == null)
uri = ((HttpServletRequest) request).getServletPath();
401 String baseURI = uri.substring(0, uri.lastIndexOf('/'));
path = baseURI+'/'+path;
}
return path;
}
The code is trying to convert the weblmpagetop.jsp relative
path to a path from the root of the webapp. What Jasper has to
work with to establish where weblmpagetop.jsp is located is
failing the uri.lastIndexOf('/'). This suggests the problem
is related to the forwards that are occurring prior to reaching
the include. Perhaps there is something that needs to start with
a '/' that doesn't.
I can't say that this isn't due to a quirk, bug, or spec ambiguity,
as opposed the webapp doing something wrong with respect to
the Servlet 2.2 spec. It sounds like you are stuck with 3.3.1
as is. Hopefully a reasonable workaround can be found.

I am currently working on a web application that uses
Tomcat 4.1.27 and JDK 1.4.2_03.
The same piece of code now needs to be supported on Tomcat
3.3.1 and JDK 1.4.2_08. I managed to get the classes, jsps
coompile and built by modifying the ant script. In fact even
the application runs perfect and the functionalities are
working as expected. Although, all is not good as it seems
so. In the backend, the tomcat - startup windows isn't quite
happy with the changes. I repeatedly get the following error
and I can make out very little from it.
I can think of possible cause as this code in my jsp but not
really sure:
jsp:include page=weblmpagetop.jsp flush=true
jsp:param name=disable-session-validation value=true /
jsp:param name=body-title-text value=%= title % /

Tomcat unusable when logging set to debug mode
Hi all! Because of a mistake in writing in my log4j configuration logging has been set to debug mode.

I had to stop Tomcat and delete the webapp from the webapp-directory manually. This is not very useful if there are running several, frequently used webapps...

RE: Error loop for R - Tomcat 3.3.1a
Hey Larry,
Finally a refresh click brought a smile on my face :-)
Yeah, it is one of those scenarios where people want backward support as
against to moving forward.
One thing that I dont understand is that the UIs are working very well. In
fact I am able to change the password (that is when these exceptions are
thrown) and is updated as well. Then why this backend exception. Any thoughts
here?
Also, there is a forward that is called before the include as you pointed
out. Do you have any ideas on what tweaking I can try?
Thanks again for your reply.

The code where the exception is occurring is:

The code is trying to convert the weblmpagetop.jsp relative
path to a path from the root of the webapp. What Jasper has to
work with to establish where weblmpagetop.jsp is located is
failing the uri.lastIndexOf('/'). This suggests the problem
is related to the forwards that are occurring prior to reaching
the include. Perhaps there is something that needs to start with
a '/' that doesn't.
I can't say that this isn't due to a quirk, bug, or spec ambiguity,
as opposed the webapp doing something wrong with respect to
the Servlet 2.2 spec. It sounds like you are stuck with 3.3.1
as is. Hopefully a reasonable workaround can be found.

RE: Error loop for R - Tomcat 3.3.1a
I'm afraid I don't have any simple guesses as to
what to change. It appears there are multiple forwards
occurring and it may be the multiple that is the
root cause of this behavior. You can experiment with
changes to see what happens, or try to run tomcat in
a debugger to see if you can determine what
((HttpServletRequest) request).getServletPath() is
returning and why it doesn't have the expected '/'.
If you want to try the latter, source for Tomcat 3.3.1
or 3.3.1.a can be found here:
http://archive.apache.org/dist/tomcat/tomcat-3/archive/
An alternative to debugging is to create a classes
directory under lib/container and extract the source
for PageContextImpl into the package appropriate
subdirectory. Then add System.out.println()s, and
compile. When Tomcat is run, the PageContextImpl under
classes will take precedence over the one in
jasper.jar, allowing you to gather clues.
HTH,
Larry

Using Tomcat 5.5 as a standalone web server
Hello all, I am running a reasonable sized site, on Linux Red Hat + Tomcat 5.5.7. The site is serving mainly Flash movies and servlets with streaming video through a commercial codec, plus a full HTML version of the site. Currently, I have Tomcat 5.5.7 integrated with Apache 2.0.46, which was (very) difficult to set up, and now I am looking to rebuild my server into a better configuration, I want to simplify my admin by running Tomcat on its own to serve all content. My question is this : does anyone have experience of running a 500 000 - 1 000 000 page impressions / month site, including elements such as I mention above, on Tomcat alone? I want to avoid the web server integration if Tomcat is up to it, but I would love to hear if anyone else has been successful with Tomcat standalone before I do? Many thanks!

If you are happy to have everything as key-value pairs you can come away with two tables. Add a table with columns kay, values and a foreign key to the suggested tree table. If you want specific data integrity per type you will have to have one table per type. It also seems that some data is there for all types (permissions, date and author). Maybe you want to reuse that definition in one table. In the end it depends on what you will be using this tree of data for, how will you access it and what technology will be used? Will it be read-only or both reads and writes? Volumes? Number of users? If data is to be updated by several users I think youl should definitely use a relational database of some kind. If it is read-only then XML files will be good enough. Hibernate is a good persistence framework to use if you want to do the modeling in XML or Java.

Re: How do I log to file jasper compile error messages?
I am migrating from version 4.1 to 5.5 and am wrestling with the logging.
How do I get compile errors from jasper to go to a log file instead of the

the below entries to the {catalina_home}/conf/logging.properties file. But
when I call a jsp page with a compile error, I see the error on the console
but not in any of the log files. Any pointers as to what I am missing?

Thanks for the suggestion. I added this line right after the
handlers=... line, but there is still no change. The mpower log file
is created, but jasper compile errors are not being logged to it. Is
jasper running under a different classloader? ... and would this confuse
logging? This suggestion makes sense -- why wouldn't it work?

There is quite an easy sollution. Run squid as you main webserver and as a web accelator in front of your tomcat. From the squid config you can decide what your want cached and what now. I don't understand why this is not done more often since its A) a very easy sollution B) does not loose any of the funtionality tomcat can offer you C) allow to fine grain the load of tomcat completely Only downsite, the squid cache in core memory gives of course the best performance so as much memory as possible will help.

Reading Sessions from Persistent Store
I am attempting to use non-sticky sessions using a syncronous Persistent
Manager and a JDBC Store.
I have written a class SyncPersistentManager that extends
PersistentManagerBase and implements HttpSessionAttributeListener to
store the sessions in the JDBC store each time an attribute in the
HttpSession is modified.
Is there a simple extension point that I can use to get Tomcat to read
the session from the store if HttpSession.getAttribute is called. I was
hoping to be able to implement this functionality via some extension
point rather than having to modify the StandardSession object as the
Session object does not appear to be pluggable (unless I'm missing
something).
Anyone have any ideas?
Thanks,
Gary Blomquist

RE: JDBC Session Persistence in a cluster problem/question
I am looking into this as well. It appears that you must use sticky
sessions with the Persistent Manager/JDBC store to get failover to work.
However, it also appears that due to the asyncronous persisting of the
sessions, you might still lose some session data.
I have written a manager that will store sessions syncronously.
However, I haven't yet figured out how to develop functionality to read
the sessions in if they are dirty based on last access time. I am
attempting to develop this by extending rather than modifying Tomcat. (I
have made a couple of related posts.)

problem/question
Date: 10 January 2006 5:42:51 PM
To: [EMAIL PROTECTED]
[For context, Tomcat 5.5.12]
Hello all,
I'm having a bit of trouble understanding exactly what the capabilities
are of the whole PersistenceManager and how it saves session data.
here's what I we have configured in server.xml:
Host name=localhost appBase=foo
Context path=/ docBase=${catalina.home}/app/mel/
Manager
className=org.apache.catalina.session.PersistentManager
Store
className=org.apache.catalina.session.JDBCStore
connectionURL=jdbc:inetdae7:tower.aconex.com?
database=paulamp;user=sqlamp;password=sql
driverName=com.inet.tds.TdsDriver
sessionIdCol=session_id
sessionValidCol=valid_session
sessionMaxInactiveCol=max_inactive
sessionLastAccessedCol=last_access
sessionTable =tomcat_sessions
sessionAppCol = app_name
sessionDataCol = session_data
/
/Manager
/Context
/Host
Sessions are persisting, as we can see the new rows being added to the
DB. Fine, great.
However in our test cluster environment we have noticed that session
variables (strings, Integers) are being lost during the failover to
the other node in the cluster. From looking at the Javadoc of the
PersistentManager and other related info on the net, I can't see
anywhere where it indicates that the Session is persisted to the DB when
the session is updated/modified/addedto. It seems to only have settings
that set how long to wait before saving to the persistence store.
1). Am I correct in my understanding so far?
2) . If so, is this design because of the likely performance impact of
all these session changes, and the somewhat unlikely case of the server
going down in the first place.
3). do I have any options here? We really do need a pretty seamless
failover with session information being kept in sync as it failsover to
the other node in the cluster.
cheers,
Paul Smith

FW: JDBC Session Persistence in a cluster problem/question
If you used the syncronous persistent manager I posted with sticky
sessions I think you would not lose data on failover. However, I just
developed it and have barely tested it at all. I was hoping for some

You can use jsvc to run tomcat as a non-priviledged user on port 80. That is very interesting - I was not aware of that capability of jsvc. Currently neither of my production operating systems (Mandriva and RedHat) offer this as a package, but I'll check it out. I'm running it on OpenSuSE and have previously run it on Debian and Fedora Core 4. None of these distributions offer jsvc as a package either. The source code for jsvc is included with the tomcat binaries in the bin directory. You have to gunzip the file jsvc.tar.gz which will create the subdirectries containing the source you'll need to compile. You'll then need to compile jsvc and write your own init.d script. You'll also need to edit server.xml and change the connector port from 8080 to 80. I'll send you a copy of my init script you can used as a template if you'd like but basically it's just /etc/skeleton altered to launc jsvc. -- Oded ::..

Re: Help - org.apache.jasper.JasperException: Unable to initialize TldLocationsCache: null
Try it without the taglib.../taglib in web.xml. Tomcat (and any other JSP-2.0 container) will pick up a .tld in /META-INF of a jar file in WEB-INF/lib automagically. Unfortunately, Jasper is hiding the root cause of the Exception that is being thrown, so I can't see why it's unhappy :(. If the above doesn't fix anything, check the file permissions under WEB-INF (e.g. the user Tomcat is running as can read and list all directories).

Google isn't offering much. I have also included my web.xml below. One site on google mentioned that taglib declarations should no longer use the !DOCTYPE .. command.

Re: Compiling Servlets - Tomcat 5.5
Lenandlar, I do not understand why you had to move the servlet-api.jar. Can you echo your $CLASSPATH and your $TOMCAT_HOME? Did you get Tomcat started?

AW: Question regarding tomcat class path handling
3. You might even wish to see if you could copy classes into the classes folder while Tomcat is running. That way the web apps would get reloaded. You'd need to configure Tomcat to recognize the Web apps to be reloadable, of course. Or you might use an ant build-file which first stops the application, then copies/updates the classes/jars and then starts the webapp again (see http://tomcat.apache.org/tomcat-5.0-doc/manager-howto.html#Executing%20M anager%20Commands%20With%20Ant).
