Subject: Tomcat 6, SQL Server 2005 JDBC Realm not working
I have a web app that connects to my SQL Server 2005 Database with no
trouble using this code:
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
con =
DriverManager.getConnection("jdbc:sqlserver://server-2006;databaseName=v362;user=user;password=dbase");
My application runs fine and I can see data from the database.
Now when I try to set up a Realm to do Database authentication I get an error:

Does any one have this type of authentication working with MS SQL

RE: SSL Tomcat and Apache.
Hi: I am not an expert but just a thought. Apache is proxing to tomcat (I assume that both at the same server) if this comunication is internal, the browser (user) just contact apache thru an enchripted comunication (https) and apache determines what to do, am I right? why do you need the internal comnication to be enchripted as well? If you make it posible (double enchription) you probably add double security to the user, a single one is not enought?

You should be able to use the same key for both Apache and Tomcat. However... If you're using Apache to forward all requests to Tomcat via mod_jk then it is my understanding that you do not need SSL for Tomcat.

Re: Comet: Unsufficiently synchronized recycling decisions
The explanation is enough, thank you for the detailed info. yes, having two different flags can make life difficult for us, I will look into it. Filip Reich, Matthias wrote: Filip, thank you for the response. The issue is fairly simple: At some point in time (t1) the CoyoteAdapter.service (or the CoyoteAdapter.event) method calls request.isComet(). If the CometEvent has not been closed at (t1), this method returns true and request and response are not recycled. At a later point in time (t2), after returning from the call to the CoyoteAdapter, the Http11AprProcessor.process (or Http11AprProcessor.event) method checks the comet flag. If the flag is false at (t2), the processor will be recycled. In almost all cases the comet flag is still true at (t2) if request.isComet() had returned true at (t1). However, especially in heavy load situations, another thread may be scheduled between (t1) and (t2) and call event.close() . In such a situation, the comet falg will be false at (t2) and the processor is recycled while request and response are not recycled. The processor will then process the next request with non-recycled request/response objects. My quick and dirty fix calls the recycle methods of request and response whenever the recycle method of the processor is called, regardless if request and response had been recycled before or not. It is not that easy to provide a simple example app that produces such a behaviour reliably. I can see that it happens in my application which runs an embedded Tomcat and a whole bunch of additional threads when the system is under load, but it does not happen in a simple test situation.

A non-recycled request object appeared in a BEGIN event if the previous request processed by the same request processor was answered asynchronously directly after the BEGIN event. In such a situation my Servlet sometimes did not get an END event, i.e. the CoyoteAdapter was not triggered again and therefore could not recycle the Request object. Nevertheless, the request processor was recycled, i.e. readded to the processor pool. As the processor was recycled, the cometEvent.close() must have happened *after* CoyoteAdapter had made the decision not to recycle Request/Response, but *before* Http11AprProtocol had made the decision to recycle the processor. To verify this, I modified the methods Http11AprProcessor.event and Http11AprProcessor.process. I replaced every occurrence of: recycle(); within these methods with the following lines: org.apache.catalina.connector.Request req = (org.apache.catalina.connector.Request) request.getNote(1); org.apache.catalina.connector.Response res = (org.apache.catalina.connector.Response) response.getNote(1); req.recycle( ); res.recycle( ); recycle(); I know that this is a hack and must be solved in a better way (and also for the NIOConnector), but with these modifications I enforced a single decision point for recycling of Request/Response *and* the processor. When running Tomcat with these modifications, my Servlet no longer received non-recycled Request objects.

Re: Data Sources Overwritten
Jeff, look I'm not sure, but it shouldnt do that. Just make absolutely sure that the app is closing those connections, ie giving them back to the pool only reason I can think you get this behaviour. If you dont close them properly... eventually Tomcat will break... it wont have another connection to hand out. If you look at the documentation there is an eg at the bottom that shows u how to make sure you do it right. - Original Message - From: "Jeffrey C.

Then in Web.xml, just looks like a mapping of the pool objects to a database object... and then finally your application will get the context, which really just grabs a connection from the pool, and returns it as a javax.sql.DataSource to your application.

Re: Data Sources Overwritten
Jeff, I dont use JNDI for dbs, got my own, but its sounds like you just not configuring some xml somewhere... On your system have a look at this link... http://localhost:8080/tomcat-docs/jndi-datasource-examples-howto.html As I said, no expert, but you can see that in the server.xml, thats where the pool is actually setup. So those setting will say create 20 dB connections. This is done so that your app reacts quickly. Then in Web.xml, just looks like a mapping of the pool objects to a database object... and then finally your application will get the context, which really just grabs a connection from the pool, and returns it as a javax.sql.DataSource to your application. Anyway have a look at that and if you think you have it all, post the equiv snippets of your config, and I'm sure the guru's will spot the problem. If I had to guess, I think your problem is in server.xml, because when you do it yourself, thats where it should have happened. ie when the server starts up, it will make the pool and thats probably why it kills the pool every time its started. good luck... - Original Message - From: "Jeffrey C.

Re: Data Sources Overwritten
David, Where do I put this context.xml file? I noticed that when I deploy the app using manager, then configure the data sources using the admin tool... that a file names mrs.xml (mrs is the name of the application I am deploying) is created (/usr/local/tomcat/conf/Catalina/localhost), it contains all of the data source information and app works fine, long as it is there. However, this file gets removed when I deploy via the webapp again, and then... the application is broken again. So, obviously the contents of mrs.xml are right, because the app works while it's there... so you're saying I need to put this information into context.xml, where should I put this context.xml file in the filesystem? Is it odd that this mrs.xml gets deleted when I deploy the app via the manager? I'm pasting the contents of the mrs.xml file below, again.. as long as this mrs2.xml is in the directory noted above, the app works... but as soon as I re-deploy the app through the web interface, this file gets deleted and the app no longer works...

We use different context.xml files for each environment. We use ant to build everything, so it's as simple as setting "release-type=prod" and then all of the configuration comes out of the "prod" directory. Since we place no restrictions on the value of "release-type", you can set it to anything you like and files will be pulled from the "conf/[whatever]" directory and put into the WAR (or wherever). This requires some work with ant to get things set up, but I think it's completely worth it. - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.7 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFGcWSF9CaO5/Lv0PARAsdMAJ4tPoj6g0UK0vUNFH8scD8qs/S7rgCdEv41 GN1yn3pMq9ghSTmm5IlA4s0= =OVar -END PGP SIGNATURE- - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
How do I match the database Resource in the Context depending on the development environment ?
Hi all I'm using Tomcat 5.5, and am setting up Connection pools for the database, using the context.xml file from the META-INF directory. We do / will have a multi region series of dev environments (local, dev, UAT, PAT, Live etc) as the code gets developed. Each Resource will point to a different database, and need different connection settings, e.g My question is how do I put multiple Resource elements within the Context element, and ensure the correct Resource is read for the correct environment ? The only real idea I have so far on how to do this is to use a different 'name' attribute values for each Resource, and determine which 'name' to select based on the value in a properties file that would say which environment (dev, Live) was in use. But I can't be the first one to run into this problem, and Google wasn't any help. Can anyone give me any hints on how they've done it, or if there's a best practice ? The Tomcat documentation wasn't any real help, and I don't want to have to edit the file before deployment etc. If I'm on the wrong track completely , let me know.

mod_jk along side mod_dir -- How to get PHP to be seen as a default page
Hello, First, my apologies for inadvertently hijacking a previous thread. Long time reader, first time poster. Won't happen again. Now, First the versions: Apache : 1.3.33 Tomcat: 6.0.13 mod_jk: 1.2.23 I am currently working on upgrading our environment to a newer version of Tomcat and mod_jk, and seem to be running into an issue with mod_jk and mod_dir. More specifically, the issue I am running into is the default file list. As I understand, it is intended behavior for the Apache DirectoryIndex directive to be more or less ignored, and instead the directive in web.xml is used to determine which files are loaded and in which order by default. Now, the issue I run into is that I do not know in advance what our customers will be loading on their site. There is a very real possibility that they may have an index.php file, which we want to have load first. This is something that I want to have Apache load, instead of Tomcat attempting to parse it, since we run php in a sandbox (suPHP). Everything I have attempted, ends up basically the same when attempting to view a site by the hostname only (ie., http://hostname.tld/) If I add index.php to the in my web.xml, it simply asks me to download the php file, instead of it being parsed by Apache. If it is not in the welcome-file-list, it simply goes to the next one that is (index.html) and is still parsed by Tomcat, not Apache. The related Apache Jk settings are as follows: In addition, after the mod_jk include, but prior to any Jk settings, I have the following: LoadModule dir_module libexec/mod_dir.so LoadModule jk_modulelibexec/mod_jk.so DirectoryIndex default.html default.htm index.php index.shtml index.html index.htm home.html home.htm welcome.html index.jsp SetEnvIf REQUEST_URI ^/(.*)/*.php$ no-jk SetEnvIf REQUEST_URI ^/(.*)/*.html$ no-jk JkWorkersFile /web/conf/workers.properties JkUnMount /*.php local JkMountFile /web/conf/uriworkermap.properties JkLogFile /web/logs/mod_jk.log JkLogLevel info JkLogStampFormat "[%a %b %d %H:%M:%S %Y] " JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories JkRequestLogFormat "%w %V %U %T" The contents of workers.properties are: worker.list=local,jkstatus # Set properties for worker1 (ajp13) worker.local.type=ajp13 worker.local.host=localhost worker.local.port=8009 worker.local.lbfactor=1 worker.jkstatus.type=status worker.local.mount=/ /* The contents of uriworkermap.properties are: #exclude extensions !*.html=local !*.php=local I understand that there are a few settings that are redundant, but I have tried every "don't touch php, tomcat" setting I can find, and it is still attempting to parse it. Also a thing to note. This only happens when attempting to view the default page. If I browse directly to http://hostname.tld/index.php, it works fine. So, my question is, how do I either prevent Tomcat from handling these requests, or tell it to pass them back to Apache if it doesn't know what to do with them? I thank you for your time and help in this matter, Dan D.
Re: Data Sources Overwritten
Best bet is to configure it manually in the context.xml for the webapp. I've never had good luck with the administration webapp in the very few times I've tried to use it. You describe tomcat as over-writing the config submitted via the admin webapp. It's more likely the admin webapp is changing the running state of tomcat but not persisting those changes to disk. When you restart, it's as if you never made any changes at all. --David Jeffrey C.

RE: Comet: Unsufficiently synchronized recycling decisions
Filip, thank you for the response. The issue is fairly simple: At some point in time (t1) the CoyoteAdapter.service (or the CoyoteAdapter.event) method calls request.isComet(). If the CometEvent has not been closed at (t1), this method returns true and request and response are not recycled. At a later point in time (t2), after returning from the call to the CoyoteAdapter, the Http11AprProcessor.process (or Http11AprProcessor.event) method checks the comet flag. If the flag is false at (t2), the processor will be recycled. In almost all cases the comet flag is still true at (t2) if request.isComet() had returned true at (t1). However, especially in heavy load situations, another thread may be scheduled between (t1) and (t2) and call event.close() . In such a situation, the comet falg will be false at (t2) and the processor is recycled while request and response are not recycled. The processor will then process the next request with non-recycled request/response objects. My quick and dirty fix calls the recycle methods of request and response whenever the recycle method of the processor is called, regardless if request and response had been recycled before or not. It is not that easy to provide a simple example app that produces such a behaviour reliably. I can see that it happens in my application which runs an embedded Tomcat and a whole bunch of additional threads when the system is under load, but it does not happen in a simple test situation.

1) revise war build process to force inclusion of libs

Copy seems easier than play with classloader...
Here is my solution which I tested and it works pretty fine:
1/ in conf/context.xml I put:
2/ I put my foo.FooListener in jar and then in ./server/lib/
3/ source code:
/** FIXME polish, add logging, exception handling, etc */
public class FooListener implements LifecycleListener {

public String getExtDir() {

if (event.getSource() != null) {
final StandardContext ctx = (StandardContext) event.getSource();
final File dir = new File(getExtDir());
File[] files = dir.listFiles();
for (int i = 0; i < files.length; i++) {
ctx.getLoader().addRepository("file://" + files[i].getAbsolutePath());
}
}
}
}
/**

*
* @param extDir
*/
public void setExtDir(String extDir) {
this.extDir = extDir;
}
}
That's all, it works fine, it does not affect classloader hierarchy
and it is logically equal to copy-based solution.

Using shared Spring Webapp in Tomcat 6
Hello, I am about to finalize some early state Spring web application (just the persistence and logic part). I am using Hibernate to retrieve data from a database. I created the whole logic using the Spring framework; at the top there is a Session Facade providing access to all the services. At this point I want to create JSP/JSF views in another webapp. I want to create a new web application that *USES* the services of the one described above. For Tomcat 6 there is a folder called "$CATALINAHOME/lib" that is said to be used for that kind of stuff. But isn't this folder meant to be used for jars instead of complete running web apps? 1.) Does it work to create a war file from my services webapp and put it into the lib directory? Is this the way to go? 2.) Furthermore: Where do I start with my JSP/JSF view webapp? I assume I have to access the SessionFacade somehow. I will have to access the logic web app from within my view-webapp. I'd appreciate some hints on that!

It turns out I had to RTFM.
"Quick Start:
3. Place a copy of the JDBC driver you will be using inside the
$CATALINA_HOME/lib directory. Note that only JAR files are
recognized!"
I only had it in my Web App lib folder

Re:[OT] Tomcat Server CPU utilization goes upto 400%
Sumit,
Since this is not a Tomcat issue I tagged it as OT.
Is the data query different for each user?
If no, setup a separate thread on startup to do the query and process it as
far as you can. I was able to create a String that was the body of the page,
then each request that came in simply inserted the string in a
document.write on a jsp. It made the response ultra fast.
If yes, look at the data returned. How much are you having to process the
data? I had to iterate through the results of three query's, create objects
and populate the fields from other queries. Then do a sort on the object. It
was very processor intensive. Is there anything you can do with a stored
procedure on the database side. You need to limit the amount of work done on
the data.

Sumit,
Look at the design of the app. Is each session doing a query every 30
seconds? Also is the database on the same server?
I had an app that was originally designed to be for a few users that
each
session hit the database. Due to the amount of processing of the data it
had
a snowball effect that after more than a few users connected the system
began to fall behind and the system came to a crawl. Since my query was
the
same for all users, I was able to spawn a thread to do a query every few
minutes and cache the results, then each session grabbed a copy of the
cached data from memory.
I would also have to agree that it appears to be an application issue,
especially after experiencing it myself. Or more accurately doing it to
myself.

There is an application deployed that refreshes after every 30 seconds.
After every 30 seconds, it requeries database and fetches the data. This
was a design requirement for this application. Generally large numbers
of sessions of this application are running (450-500).
