I have tried setting the MIME mapping in web.xml for this site such as: mime-mapping extensionxlt/extension mime-typeapplication/vnd.ms-excel/mime-type /mime-mapping (I have tried also msexcel, excel). But I still can't get the browser to run Excel. When I put the same file onto MS IIS server and try to download it, Excel runs and opens the file correctly. I have inspected HTTP requests and responses from both servers and found no relevant difference. I also have similar problem with dot file type (MS Word document template). I have added the following to web.xml: mime-mapping extensiondot/extension mime-typeapplication/msword/mime-type /mime-mapping and when I run the Tomcat server on localhost while developing, this works fine and runs Word. But when I deploy the application to production Tomcat server, Word is not run and binary file is displayed again. With dot file type this does not work in either case (as mentioned above).

RE: [OT] Re: log4j.properties file co-opting container logging. - Found word(s) optin in the subject
-Original Message- From: Jacob Kjome Do you know what logger is used by default by commons-logging in Tomcat if log4j isn't present?

RE : Synchronization in cluster
Hi, What are your needs? Why distributed singleton or distributed locking are so important ? Perhaps you can use Database to implement locking functionality and Jgroups library to replicate state (or distributed singleton) across members of a group (see www.jgroups.org). -Message d'origine- De : Igor [mailto:[EMAIL PROTECTED] Envoyé : mercredi 29 septembre 2004 20:42 À : [EMAIL PROTECTED] Objet : Re: Synchronization in cluster Hello! if you are talking about distributed locking, then the answer is no Thank you for reply ! Our web application uses locking and Singleton pattern. I am making researches - is there a possibility to move to cluster architecture or load balancing. Distributed locking is not possible. Distiributed Singleton (static variables) seems not to be possible too. So web applications, that use locking or Singleton cannot use cluster architecture or load balancing. Maybe there is indirect way of implementing distributed locking or distributed Singleton? For example, code that needs synchronization may be concentrated in main Tomcat, and other Tomcats will call this code via http or SOAP? Is there any way to move web application with locking and Singleton to cluster or load balancing?

RE: WAR file deployment snag - any suggestions?
Thanks very much for this. There are some very good points in here that have got me thinking. At present I have only one Tomcat running and a small number of users (it's an intranet) but the complexity and resource requirements of the application set is growing. I don't have any experience of larger scale web systems so all suggestions are welcome. Saving the XML files was an initial step at caching things that I can control. I did play around with holding onto the (dom4j) Documents in the ServletContext but I was concerned that this would swallow all the memory unless I used some sort of soft-reference caching system. I posted a question about this to this list - but I never heard back - must have been too dull a question (or the wrong list)! I imagine spreading the apps over multiple Tomcats/machines would allow me to do more in-memory caching. Feels like this is a move toward Web Services - I don't know much about them. Thanks again for your response - I'd be interested in hearing any other pearls of wisdom.

That's one option; but another (likely more scalable) idea would be to put files in a filesystem, where they belong. The idea is to setup a directory outside of the Tomcat context path -- specify it in a properties file, or in a context param, whatever -- and write the data there. As the system grows to support multiple Tomcat instances spread across different machines, you could share the filesystem via NFS (not pretty, but it works), stuff the docs in a database (not pretty, but it works), or have the mid-tier Tomcat instances push the data to another, internal Tomcat setup that writes the files to a clustered/RAID'd fs. etc, etc, depending on how valuable these docs are and how much this app grows. By not writing to your context, you can wrap everything up in a WAR file and, better still, gain (a little) more security by making the WAR file owned and served by two different user accounts. -QM -- software -- http://www.brandxdev.net tech news -- http://www.RoarNetworX.com - 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]
Re: Norton AntiVirus and False Positives In Tomcat
Sounds like NAV may have returned some false positives. The only virus-like content I would expect inside a plain HTML doc would be rogue JavaScript. Indeed. I looked at the HTML page myself - it's unaltered, and there's nothing rogue in there that I can see. Links with strange urls? Perhaps you could point your admin to the web resources you found, those concerning false positives from NAV? I agree - I already sent the link yesterday afternoon. This could become a sticky issue of corporate politics, depending on your organization's structure. You may have to get your management to talk to the admin's management. -QM You're right on there.

MemoryRealm in a Context
Setup is Tomcat 5.0.28, J2SE 1.4.2, Redhat 9. I've been using a MemoryRealm in a Host container and everything works fine. It is ideal for a computer to computer link over HTTPS to authenticate access. I've now decided that I want a different setup on a per Context basis. The docs for the realm component say that a Realm can be inside a Context container so I moved the Realm section from the Host to the Context and restarted Tomcat. Now when I try and authenticate the debug log shows that the realm is being treated as a JAAS realm and consequently fails. Is there something clever going on here that I'm not aware of or do I need to made further config changes?

What are your tradeoffs between CPU (parsing XML from disk), RAM (storing in memory), and network (pushing data between hosts)? If you design this with flexibility in mind, you can easily move between in-memory, on-disk, and fetched-from-elsewhere storage (aka web services or another webapp). -QM -- software -- http://www.brandxdev.net tech news -- http://www.RoarNetworX.com - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: Recursive stack trace with Tiles and Filter - any ideas?
Hi,
As you know signal 11 crashes are internal to the JVM usually at a
native level. A corrupt or incomplete JVM installation, or missing OS
patches for your JVM version, are the two most common causes for this.
Can you post the Java code for your error JSP? That'll make helping you
a bit easier for people who don't feel like translating your
Struts/Tiles directives to Java in their head ;)

Subject: Recursive stack trace with Tiles and Filter - any ideas?
Sorry for the cross-post, but I'm not sure if this is more of a Tomcat
or Struts issue (in addition to certainly somehow being my code issue
:). Any suggestions are appreciated.
The last week or so have been having our Tomcat 5.0.19 server on SuSE
Linux crash with a Signal 11. We are using Struts 1.2.1. When I look in
the Tomcat logs the actual cause usually varies somewhat, but several
times we have seen what looks like a loop in error handling occur. I'm
headed in this evening to run memtest86 on our server, but wonder if
there might be something else that's the root cause.
Anyway, in case there is a common cause for this that I have missed,
I've enclosed snipped portions (even then its a large stacktrace) of
the latest exception we received today. Obviously somethings in a loop
and we either run out of memory, getting the Signal 11, or we go into a
section of memory that's bad. Both my error.jsp page and another JSP
page (PoStudent.jsp) are almost always involved.
The error.jsp is pretty simple, I've enclose it below just before the
stack trace.
Thanks in advance for any ideas - Richard

If that is the case, maybe you should look at Coherence. distributed locking is meant to solve a specific problem, so unless you really need to synchronize distributed objects like a distributed cache, I would avoid using it. some people tackle type of problem with JMS. unless you plan to extend TC5 session replication with these features it's going to be a while. peter On Thu, 30 Sep 2004 09:41:41 +0200, LERBSCHER Jean-Pierre [EMAIL PROTECTED] wrote: Hi, What are your needs?

RE: org.apache.commons.digester.Digester error--- at tomcat startup...
Hi, As the error says pretty clearly, you can't put resource-ref before servlet using your DTD. So the same web.xml doesn't work on Windows or any other platform. Go validate your web.xml (using a tool like XMLSpy or one of the free online validators) to see for yourself. You can simply fix the element order and stick with the 2.3 DTD, or move to the 2.4 schema (if using Tomcat 5.x) and then the element order doesn't matter.

method level synchronization doesn't work
Hi,
I am using Tomcat 4.1 and I am accessing MS SQL Server database via JDBC. I
have a JSP that calls a web bean. This web bean has a section of code that
I want to synchronize, but when I synchronize the method, Tomcat doesn't
actually synchronize the threads. (I tried this by having 2 users access my
JSP at the same time). When I synchronize the code in the method by using a
mutex, it works.
So, doing this doesn't work:
public synchronized void amethod()
{
//some code that access the database and needs to be synchronized
}
But doing this works:
public void amethod()
{
String mutex = ;
synchronize(mutex)
{
//some code that access the database and needs to be synchronized
}
}
Why does synchronization on the method doesn't work? Does Tomcat not allow
locking of object caused by method level synchronization? Any help will be
appreciated.
Thanks,
Malia
RE: Using shutdown script for different port
Back to my original issue--I was having trouble shutting down Tomcat when the shutdown service was listening to a non-default port, but have since sorted it out. After going through the source code, I found that when processing the shutdown command, the Bootstrap system just uses the configuration in CATALINA_BASE, so all you need to do change the port in server.xml, and make sure your shutdown script references the correct directory hierarchy. Thanks, Dhruva --- Steve Kirk [EMAIL PROTECTED] wrote: OK. I didn't realise that, although I suppose it's obvious in hindsight.

Check your environment variables.
CATALINA_HOME c:\tomcat or wherever you installed tomcat
Seem you have this set properly
CLASSPATH

There are different ways to do this but it seems like you need to have
The servlet-api/jar in your CLASSPATH variable. Mine is in
c:\tomcat\common\lib
JAVA_HOME c:\j2sdk1.4.2_03 or wherever you installed the jdk

Re: method level synchronization doesn't work
am I missing something, but looks like you're trying to build some
kind of web cache. why not use Hibernate or something that already
does caching for you instead?
the only time I can see a need to sync, is if the request contains
data that requires a transaction. Which in that case, you're better
off doing an insert, then a second select query with the same
connection.
or is the scenario a distributed objects setup?

RE: Tomcat 5.0.27 - Single Sign On PROBLEM
Hi,
As the SSO docs say, it's designed to work over a set of web
applications in a *particular virtual host*. Enhancing it to work
across a cluster would be nice, but it would be exactly that: an
enhancement. What you're reporting isn't a bug, it's a limitation, and
you're free to submit enhancement patches for it. It's of course not
trivial, but possible to accomplish what you want. If you don't do it,
it might still get done, but we can't know when as it depends on whether
someone needs it or is interested in the area.

RE: Tomcat 4/Apache 2 Connector slow down
Try turning off ip to name resolution, this can sometimes be very slow and seemingly affect different PCs/servers differently. I'm no expert on what might cause the slowdown in your case, but I have experienced what sound like similar problems in the past. From the default server.xml file for v5.0.27: By default, DNS lookups are enabled when a web application calls request.getRemoteHost(). This can have an adverse impact on performance, so you can disable it by setting the enableLookups attribute to false. When DNS lookups are disabled, request.getRemoteHost() will return the String version of the IP address of the remote client. The same adverse impact can also be caused when converting IP to name for logging purposes. -Original Message- From: Steve Forsyth [mailto:[EMAIL PROTECTED] Sent: Thursday 30 September 2004 00:50 To: [EMAIL PROTECTED] Subject: Tomcat 4/Apache 2 Connector slow down I have a very bizarre situation: I have everything working as far as the connectivity between Tomcat 4 and Apache 2 with both the JK and JK2 connectors (of course not at the same time :) I am currently testing on 2 computers... both connected through the same little hub and both have the exact same IP configuration coming from DHCP. However, computer A (my computer) hits the websites and runs just fine Whereas, computer B hits the websites and reacts in different ways depending on what my setup is and how I hit the website... explained hereafter Different ways of hitting the website and the different configurations (only affected computer B) 1) Using JK connector and port 8080 (so bypassing Apache 2): Everything flies 2) Using JK connector and port 80 (going through Apache 2): Moderate slow down of about 4 to 5 times slower than going direct on port 8080. So a page that would come up instantly now comes up about 2 to 5 seconds 3) Using JK2 connector and port 8080:Again, everything flies 4) Using JK2 connector and port 80: EXTREMELY SLOW... something happens that makes the connection go slower than a modem... on a LAN. We sniffed the traffic (unfortunately, none of us are all that good with exactly what we are seeing so we had to rely on what the sniffer was telling us) and it looks like there is some very fast handshaking for a few packets back and forth and then a WINS packet to the client, the client sends back the computer name and user name and the server sits on it for about 7 secs... the server sends another WINS packet... sits for another 7 secs this all happens for about 30 secs and then the server starts sending packets but slowly. So... all in all... it takes 30 seconds to send a page that normally takes far less than a second if going directly to Tomcat via port 8080. The part that makes this whole thing interesting is the fact that I have found my computer... and the other servers seem to not be affected by any of this... and yet most of our pcs... which are of varying speeds, types, (however all are windows OSs... XP and NT4). I haven't seen any difference between IP settings or any other network settings. However, I must admit that I'm a developer and not a net admin :) Anyway, anyone have any ideas or comments... places to search? WINS is about the worst search term that you would want to search for since it never pulls up exactly what you are looking for :) Thanks, 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]

RE: method level synchronization doesn't work
Actually, the data that I am modifying requires a transaction and
synchronization. It increments a counter stored in the database. So, I
have to do a select to get the current value, increment the counter, and
then insert the new value. So if two threads are accessing it at the same

context sharing problems
Hi, I am trying to share the same class files (and libraries) between two different web-apps one running in ROOT/ and one is admin/ Basically, I want the first one to run from the default context ie http://www.x.com/ And the second web-app to run as http://www.x.com/admin However, all of the classes for both web-apps are situated in the first one (ROOT). This may seem a strange way of doing things, but I need to reflect the changes made in admin (basically a collection of jsps etc) in ROOT (a series of filters etc). I have actually got this to work using a tomcat plugin in eclipse because of the way eclipse shares libraries and classpaths Does anyone know how I could do this for a standalone tomcat (running in windows)??? Just to clarify: Web-apps\ ROOT\ WEB-INF\ Classes\ My\package\name\MyFilter.class My\package\name\StrutsAction.class My\package\name\ApplicationResources.properties My\package\name\MySingletonIIWantTochangeViaTheGuiRealTime.class Admin\ WEB-INF\ Web\index.jsp Thanks for your help M --- Outgoing mail is certified Virus Free.

Re: method level synchronization doesn't work
I'd be surprised if synchronization was broken. Given one assumption I
think I can explain what you are seeing.
Assumption: The two concurrent requests are handled by two different
instances of a jsp servlet.
If there are two instances then each request will be able to
sucsessfully obtain the monitor when calling the synchronized methods.
So, why does using a synchronized block work? It works because you are
synchronizing on a literal string. Literal strings get interned into a
pool of objects by the jvm. So the mutex reference actually points to
the same piece of memory for both instances of your jsp. Hence the
synchronization works.

Re: method level synchronization doesn't work
you might want to consider using a stored procedure to make it look
like a single call from tomcat. is the goal here to make sure the
counter is incremented correctly? I'm guessing there's situations
where the counter shouldn't be incremented?
you can also use a subquery to increment the counter. there's plenty
of articles on how to do this the simple way. I hope that helps

RE: Clustering and session replication
Filip, To discard any problems in application settings, we copied an entire application from production (clustered tomcat 5.0.25) to the cluster that's having problems (5.0.28). We verified context settings and load balancing. The first time the application is used after a tomcat restart, it works well (load balancing and session replication). But after reloading the application in any node (i.e. context reloads), the log will show the warnings and timeout errors that I described before. Session replication fails from that point on. From the little I understand, I think clustering is doing its job, the problem is it cannot find the context manager for that application (despite both nodes have distributable/ in web.xml).

Re: Synchronization in cluster
sounds like your system needs a little rethinking, if you have singleton access to your DB. That is why the DBs are transactional, so that you can use connection pooling. you can use JGroups, but you might run into serious performance problems, not because of JGroups, but because of the fact that you want to lock several tomcats in a distributed lock when accessing the DB.

problems with apache/tomcat
Hello, This has gradually become a nightmare here. So I turned to here for help. We are 24 X 7 service provider and using apache/tomcat as our application server. We have one apache and 3 tomcat in a clutering/load balancing environment. Very frequently, we saw exceptions like java.io.StreamCorruptedException: InputStream does not contain a serialized object, java.io.EOFException at java.io.DataInputStream.readFully(DataInputStream.java:153) java.io.StreamCorruptedException: Caught EOFException while reading the stream header at java.io.ObjectInputStream.readStreamHeader(ObjectInputStream.java:840) There happens a lot while we have more and more users in the system. Literally, we understand what's exceptions are (or we thought we know). We did research online. Someone said it could because of network/load issue. But it does not always seem to be the case here. We also check our application and it doesn't seem there is any issue (that we can find). We are wondering if there are any settings on tomcat or apache can help to solove or allievate the issue. Second issue is that our apache does not always dispatch messages to tomcat instances correctly. It takes long time for it to find a tomcat instance (which was brought down) in the cluster is brought back again. Is this a bug in apache/tomcat? If anyone has experience on any of them and would like to share your solution and/or point me to the right place to find solution, we would greatly appreciate it.

Re: Question from a newbie! Please pardon me!
If other applications (using other packages) compile correctly, then your
classpath is correct and the problem then is that you don't have installed
the servlet jar, or it is in the wrong place, which is
$JAVA_HOME/jre/lib/ext/
The file I have is: servlet-2_3-fcs-classfiles.jar. I guess there could be
others, depending on your JDK version but the important thing is that this
jar is not bundled with the JDK.

RE: versions 2.3 and 2.4 of web.xml
Further to my note below, plus my previous posts on Who has got include-prelude to work?, I think I might have stumbled across the answers to both myself. Basically my web.xml files were based on the v2.3 files that shipped with the standard installation, and using these seems to have silently suppressed the 2.4 features, including include-prelude. Not sure if this is a bug - if web.xml encounters a tag which it knows is valid in its current version, but not in the earlier version declared in the web-app tag, should an exception be thrown, or should it silently ignore it? -Original Message- From: Steve Kirk [mailto:[EMAIL PROTECTED] Sent: Thursday 30 September 2004 17:32 To: 'Tomcat Users List' Subject: versions 2.3 and 2.4 of web.xml Only just noticed this, looks like a possible bug, but maybe there's a reason behind it?

RE: method level synchronization doesn't work
I thought Tomcat instantiates only 1 instance of JSP servlet to handle all
requests. Isn't that the reason why it's not suggested to have instance
variables? If it is the case that 2 instance of JSP servlets gets created
to handle each request, what's the best object to synchronize on?
Synchronizing on empty string is not the best option because any other block
of code using an empty string will cause thread contention. Thank you for
your help!

Subject: Re: method level synchronization doesn't work
I'd be surprised if synchronization was broken. Given one assumption I
think I can explain what you are seeing.
Assumption: The two concurrent requests are handled by two different
instances of a jsp servlet.
If there are two instances then each request will be able to
sucsessfully obtain the monitor when calling the synchronized methods.
So, why does using a synchronized block work? It works because you are
synchronizing on a literal string. Literal strings get interned into a
pool of objects by the jvm. So the mutex reference actually points to
the same piece of memory for both instances of your jsp. Hence the
synchronization works.

am I missing something, but looks like you're trying to build some
kind of web cache. why not use Hibernate or something that already
does caching for you instead?
the only time I can see a need to sync, is if the request contains
data that requires a transaction. Which in that case, you're better
off doing an insert, then a second select query with the same
connection.
or is the scenario a distributed objects setup?

actually synchronize the threads. (I tried this by having 2 users access

So, doing this doesn't work:

But doing this works:
public void amethod()

synchronize(mutex)

Why does synchronization on the method doesn't work? Does Tomcat not
allow
locking of object caused by method level synchronization? Any help will

RE: Prblm with deployment descriptor for XML RPC Servlet
Hi, Your web.xml is syntactically fine, although I suggest you change to the 2.3 DTD. Take a look at the top of $CATALINA_HOME/conf/web.xml to see the DTD declaration and copy it instead of your current 2.2 delcaration. For this servlet to be available at http://localhost:8080/locasugeGSM, you webapp must be deployed at context path (the empty string: not / or null). You can do this by overwriting the existing ROOT webapp that ships with Tomcat, or removing that webapp and adding an explicit Context declaration to $CATALINA_HOME/conf/server.xml with a path= attribute. Make sure to read the Context configuration reference in the Tomcat docs for a more complete understanding of how to configure your webapp in Tomcat. And if you haven't already read it, I strongly suggest you read the First Webapp guide in the Tomcat docs.

RE: context sharing problems
Hi, Then put the singleton in the shared repository, not in ROOT. In general, what you're trying to do is inadvisable and against the spirit of the Servlet Specification: web applications are supposed to be self-contained. Features like a shared classloader repository are not mandated by the Spec and are a convenience-type feature with different levels of support and portability across containers. Consider alternative approaches to inter-webapp communication, such as over the network, via shared storage (filesystem or DB), or via a messaging platform such as JMS.

Re: context sharing problems
I think you should evaluate how your app is designed. If you need to communicate cross context/processes you should consider using something like JMS to give you good isolation. Today you may want to have everything on a single box, tomorrow you might want other servers. Another option to consider is to change the need for a singleton type of class or store some info in a database.

Security of Servlets
We are giving some thought to putting a CGI-based Wiki, specifically OddMuse, on a website that runs on a Linux server. In 'Using Linux (Fourth Edition)', the authors warn that "The biggest cause for concern about protecting your site from external threats is CGI scripts." They go on to suggest various precautions that will reduce the risk. This has me wondering if servlets are equally insecure or have a much stronger security model. I also have Jason Hunter's 'Java Servlet Programming (Second Edition)' which has a 30 page chapter on Security that details how various forms of authentication take place in servlets. However, I can't find any categorical statement that says servlets are actually any more secure than CGI. I was wondering if someone with extensive experience with the security aspects of both servlets and CGI can give me any sense of which is more secure and why?I need this information so that we can choose the right approach for our wiki. Also, if servlets are more secure than CGI, is anyone aware of a wiki that runs as a servlet, preferably open source?

For one, there's no need to announce that you're new to
Java/servlets/etc; this forum accepts questions from all skill levels.
Second, where did you put your WAR file? Is it in
{tomcat dir}/webapps/locasugeGSM/{file}.war
or
{tomcat dir}/webapps/{file}.war
?
It should be the latter; the former (essentially) sets up a context
(webapp), the complete contents of which are a WAR file.
Check the logs to see what gets deployed at container start time.

RE: Security of Servlets
Hi, I'd say it's easier to expose security flaws with CGI scripts than it is with Servlets, and vice versa it's easier to configure a secure environment for Servlets than it is for CGI scripts. That's not the same as saying Servlets are more secure than CGI. I don't think such a categorical statement would be valid for this case, and it's a waste of time looking for such a statement. Both technologies require the system designer, deployer, and administrator to be conscious of security issues and address them proactively. That said, I'd support the statement in the first paragraph on two grounds. One is a simple historical comparison: use any search you like (plain Google, or forums like Bugtraq and CERT) and you'll see many more CGI-based attacked and vulnerabilities than Servlet-based ones. Of course some of that is because CGI is an older and was more widely used for a long time, but those facts are irrelevant for the point of this discussion. The second ground is the existence of finer grained control over Java code. To secure a CGI script, you'd have to peer-review its code, make sure the user running it has only the required privileges, etc. With Servlets, you can apply extremely fine-grained security using a variety of approaches like PrivilegedActions, SecurityManager (these two are inside the JVM and portable), the security-constraint elements in web.xml (which can also be done for CGI in most servers, like httpd), and Java's built-in controls over memory allocation and such low-level matters. So both technologies can be made secure, but it's easier to assure a given Servlet is secure than a given CGI script, IMHO. If someone has tons of experience in CGI security assessments and little in Java, they might say the opposite ;) As far as wiki implementations, let's see. Of the top of my head, Friki is Java and open source (SourceForge). MoinMoin is Python.

RE: method level synchronization doesn't work
Thank you for replying, but I would appreciate it if you could expand on your explanation. Here is my original post: Actually, the data that I am modifying requires a transaction and synchronization. It increments a counter stored in the database. So, I have to do a select to get the current value, increment the counter, and then insert the new value. So if two threads are accessing it at the same time, the counter will not be properly incremented. What's puzzling is that method level synchronization does not work while synchronizing on a block of code inside a method works. Regardless of what persistence mechanism I use (i.e. Hibernate, EJB, etc), I have to synchronize on the method that increments the counter stored in the database. I can't avoid this due to business logic. Please let me know if there is alternative to synchronization.

AW: method level synchronization doesn't work
Hi
I have to synchronize on the method ...
No you do not need to synchonize on the method, you need to synchronize.
You can synchronize on anything.
The easiest would be to do the following:
public static synchronized void amethod()
{
//some code that access the database and needs to be synchronized
}
Just make your method static.
Synchonization will not occur on the instance object any more, but on the
Class object of your instance.
Since tomcat may instantiate multiple servlets, it may only do so in the
same classloader. Therefor all instances belong to the same Class object and
will synchronize as you required.

Steffen

Re: method level synchronization doesn't work
Why not just let SQL do the update? Do the following: update my_table set counter_field = counter_field + 1 (where clause here if needed) (off the top of my head, my syntax might be off) In other words, why not let the database handle the concurrency issue? That's kind of what they're there for (partly anyway). Malia Noori wrote: Thank you for replying, but I would appreciate it if you could expand on your explanation.

So, I have to do a select to get the current value, increment the counter, and then insert the new value. So if two threads are accessing it at the same time, the counter will not be properly incremented. What's puzzling is that method level synchronization does not work while synchronizing on a block of code inside a method works. Regardless of what persistence mechanism I use (i.e. Hibernate, EJB, etc), I have to synchronize on the method that increments the counter stored in the database. I can't avoid this due to business logic. Please let me know if there is alternative to synchronization.

The same goes for creating and destroying a servlet object several times over a context (webapp) lifetime. That said, a servlet's main methods -- doGet(), doPost(), service() -- may be called concurrently for the same servlet object. These methods are thus meant to be thread-safe, and as such they shouldn't modify object instance variables.

RE: JK2 2.0.4
I've replied to your offlist email, basically you have mapped everything coming in to apache to both of the tomcats so it will always take the first matching route. You need to be more specific with your uri's and define the exact webapp names if the webapps are different across the 2 tomcats. If the webapps are the same then perhaps you could just miss out the apache section and run 1 tomcat with 2 virtual hosts. Ta Matt -Original Message- From: Paul D.

Re: method level synchronization doesn't work
Well, I'm not sure it was stated that a return value was needed. The way I read the original post was basically (to paraphrase): I need to update a counter field, and the way I intend to do it is to retrieve the current value, modify it, and then write it out again as two separate queries. If that's the scenario, I don't see any reason the SQL statement I gave (assuming I got the syntax right) wouldn't work just fine. If your saying that you need to do the update and then retrieve the value for some reason, then I agree, it's not as straight-forward. One thing that MIGHT work, although I'd frankly have to go try it myself to be sure, is a subquery, something along the lines of: select (update table set counter=counter+1) as counter from table Even if the theory is correct, I'm not sure about how database-independant it may or may not be. -- Frank W.
