Of course every time you use one you will have to use try-catch blocks. Sorry no way around that. However, if you are clever you will create data objects to hide all that stuff. Even better - why not get something to write all those horrid data objects - sql and trycatch blocks for you. Last year we (another developer any myself) developed a project called sysmod, which essentially takes a xml description of a database schema and turns it into Java code and a real SQL schema. This is by no means a unique approach - tools like JBuilder allow you to use graphical UI's and UML to do something similar - and is even two way. However, our approach is somewhat lighter. All we have is the XML model. The model generates the Java data objects. The code includes comments such that it creates nice JavaDoc as well, so in effect you have a self documenting business model from the XML. At this stage we have to write very little SQL, and no SQL at all for updating and adding records. The actions (we use struts) become very simple because in addition to being able to load and save themselves from a database they can also load themselves from a request, therefore our code looks something like this: Client client = ClientFactory.newClient(); client.loadFromRequest( client, request ); client.saveChanges(); This code essentially loads all the fields from the request prefixed by client into the data object. Then the call to saveChanges() saves the record to the database. The data objects also handle their own SQL exceptions, although they throw their own exceptions. The Factory for each data object also provides lists of various kinds, ie you can call ClientFactory.findAll() and it will return a list of Client objects prefilled by a single query. You can also do a findByQuery with parameters to define the query. The approach works very well, but is not without its drawbacks. It is quite easy to code things which look logical but create hundreds of queries and is inefficient. We are still working on ways to improve the system, such as caching data. It is also limiting - in that while it creates DataObjects it is not a trrue object hiracy. This is because the system is still based on a relational database. In other words this system is not a relational mapping tool. It is also not a object database. However, it does provide a quick and easy way to prototype databases and the Java code to access it. Currently the system creates objects that are not JDO or EJB.

execution order of context listener and servlets
hi guys, i have a question about der execution order of the ServletContextListener.contextInitialized() method and the init() method of an servlet. In my web.xml i have a servlet with load load-on-startup1/load-on-startup declared. besides i have declared an ServletContextListener. in tomcat the ServletContextListener executes first and then der init() method of the servlet. in ias (oracle) the servlets init() method executes first and then the ServletContextListener. i thought the ServletContextListener has to execute first. is this right or am i missing something? servus uli - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Cross site single sign on
Hi all! Not necessarily Tomcat specific, but I'm curious what others may have done to support cross site single sign on. The basic problem is that customer goes to site A, and logs in. Then while navigating that site, they eventually head over to site B. Of course when they hit site B, the customer should already be logged in. If site A and site B live in the same domain space (say, site.com and b.site.com), then a site.com cookie should be able to be used as a token that show login. Of course, this requires cookies. It also requires both sites to maintain the cookie if the cookie is allowed to expire (say, it's only useful for 30 minutes). However I think this would have to be a signed cookie, where both participating servers encrypt to cookie with a known key (perhaps a shared public key). Now, if you have sitea.com and siteb.com, then the cookie technique can't work (as neither can set a cookie for the other). So, I'm thinking that you can do something similiar, a signed token, in a hidden field and then having to submit a form to get to the new site. Of course, you can always stick the token on the URL as well. Does that sum it up? Any other ways for cooperating sites to transparently exchange credentials? I suppose the back ends can do it. Send signed packets to each other during their log in processes to notify cooperating services. But if your logins time out, you still need to constantly update the session information. It's not enough to know that Bob signed in at 10am, and expires at 10:30. If Bob actively uses the site, you want the time out to be since last activity. How are others doing this and what have you found effective? Regards, Will Hartung ([EMAIL PROTECTED]) - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Servlets with JDBC connectivity
Based on the how-to and modified for your app:
package yourpackage;
import java.sql.*;
import javax.naming.*;
import javax.sql.*;
public class Conn {
/**Takes desired database as a string and returns a connection.
*/
public static Connection getConn(String dBase) {
Connection connection = null;
String osName = System.getProperty(os.name);
try {
//Start of Tomcat connect
Context ctx = new InitialContext();
if (ctx == null) {
System.err.println(Conn.getConn ctx is null);
throw new Exception(Boom - No Context);
DataSource ds = (DataSource) ctx.lookup(java:comp/env/jdbc/ + dBase);
if (ds != null)
connection = ds.getConnection();
//End of Tomcat connect
} catch (Exception e) {
System.err.println(Conn.getConn + e);
}
return connection;
}
}

This may not be the right place to ask this, but if you can direct me
to the right place, I'd appreciate it.
I'm looking for a design pattern that someone must have already
thought through so that my head can stop hurting. Here's the problem:
I'm designing a webapp that has several servlets that all access a
database (or a couple of databases, actually) to either update or
retrieve information.
Rather than initializing these connections multiple times, dealing
with SQLExceptions in every class that uses JDBC queries, and
generally doing things multiple times, I thought I'd put all the
database stuff into a single class. I created a setUp() method that
initialized the database connection and then used static methods so I
could do something like
SQLUtils.executeQuery(a SQL statement);
SQLUtils.executeUpdate(another one);
anywhere in my webapp. If the database connection had not been
created, it got created before executing the SQL statement. If it was
already created, it just got done. I handled all the nastiest
exceptions in the SQLUtils class, so I didn't have to deal with them
elsewhere.
You can probably guess the next part. I've discovered I need to
connect to more than one database, and this design does not support
that. Creating instances of a SQLUtil class would be a big pain,
because then I have to pass those around between my servlets and I
lose one of the huge advantages of this approach, namely a single,
globally visible interface to the database.
I thought about multiple classes, one for each database I'm connecting
to, but I know that can't be right on so many levels. Meanwhile, I'm a
little stumped.
How do people handle this elegantly? The requirements are: a single,
globally visible (within a webapp) database interface and the ability
to access multiple databases easily.
Thanks in advance for any ideas,
Todd

Re: OutOfMemoryError
Christopher Schultz wrote: So, moving on, what usually happens is that a low memory condition triggers a GC (usually a full GC). When the GC runs, it needs some memory to work with. If it cannot allocate memory for itself, it will die with an OOM. If the heap hasn't increased, yet, then the GC cannot allocate more objects on the heap to do it's thing. That can explain why you get an OOM when you are way under the heap size in the output of ps. Hi Christopher, I have a doubt with respect to your explanation. Is there any difference between an OOM thrown within the GC thread, and any other OOM? I mean, if an OOM is thrown within the GC, and it dies, the JVM looses its GC, so no memory can be deallocated, and the only way is to shutdown the JVM. But what happens if the OOM is thrown in any other thread? Is the JVM state preserved in this case? As said in another post, generally speaking, an OOM leaves the JVM in a bad state. But, can this state be detected by checking the state of any of the JVM threads? I guess the GC should run in a thread I could get a reference from. If I check this reference liveness, could I determine if the OOM has affected the GC? I have developed some web services that can return an important amount of data. Under high load, the server memory requirements can become huge, so I added a loop into the catalina script to restart my tomcat instance automatically, and added a filter that catches OOMs and forces a JVM shutdown, after writing some logs asking for more memory. I was wondering if I could reduce the shutdown condition to only the cases when the GC has died.

Re: HttpSessionListener in Tomcat 4.1.27 (or HttpSessionListener in general)
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)

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 :

accessing tomcat from another machine
I've upgraded from tomcat 4.0.4 to tomcat 4.1.29 I can access my application by using http://localhost:8080/appname Everything's ok. But if I try to access it from another machine, it fails. Even if I try to access the application from my own machine by using the computername or 127.0.0.1 instead of localhost it fails, too. If I start the tomcat 4.0.4 everything works fine. Do I miss some configuration for the 4.1 version? I can't find any hints. Thanks in advance Michael - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

NotSerializableException - DBCP
Hello, I have not been using the shutdown command when restarting Tomcat in Windows but now that I have I get exception traces for all my Session beans on shutting down and then again for each of two connection objects when starting up. Is this simply that the DBCP package's PoolableConnection Class does not implement Serializable? If so how can I get it to implement this. Is there any way to use a destroy method to remove the connection pool from the equation before persisting? Maybe using a SessionListener? All my session beans implement Serializable.

RE: HttpSessionListener in Tomcat 4.1.27 (or HttpSessionListener in general)
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

Re: Cross site single sign on
Sounds like pubcookie: http://pubcookie.org/ -Tim Will Hartung wrote: Hi all! Not necessarily Tomcat specific, but I'm curious what others may have done to support cross site single sign on. The basic problem is that customer goes to site A, and logs in. Then while navigating that site, they eventually head over to site B. Of course when they hit site B, the customer should already be logged in. If site A and site B live in the same domain space (say, site.com and b.site.com), then a site.com cookie should be able to be used as a token that show login. Of course, this requires cookies. It also requires both sites to maintain the cookie if the cookie is allowed to expire (say, it's only useful for 30 minutes). However I think this would have to be a signed cookie, where both participating servers encrypt to cookie with a known key (perhaps a shared public key). Now, if you have sitea.com and siteb.com, then the cookie technique can't work (as neither can set a cookie for the other). So, I'm thinking that you can do something similiar, a signed token, in a hidden field and then having to submit a form to get to the new site. Of course, you can always stick the token on the URL as well. Does that sum it up? Any other ways for cooperating sites to transparently exchange credentials? I suppose the back ends can do it. Send signed packets to each other during their log in processes to notify cooperating services. But if your logins time out, you still need to constantly update the session information. It's not enough to know that Bob signed in at 10am, and expires at 10:30. If Bob actively uses the site, you want the time out to be since last activity. How are others doing this and what have you found effective? Regards, Will Hartung ([EMAIL PROTECTED]) - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: response.sendRedirect() finite loop?!
Hi, On further investigation it would appear that this is not a Tomcat issue. It seems to be something to do with mod_jk. When a response.sendRedirect occurs it does not apply it properly. Or at least something is not executing properly. The setup we have is Apache 2.0.48, Tomcat 4.1.29, and mod_jk between them working with mod_ssl. I tested the code without using apache between me and Tomcat and everything worked as expected. Any suggestions or comments??

Auto start scripts
Have very limited experience of Linux or Tomcat. Not even really sure if this is a Tomcat issue or a Linux issue. Main question: How do I run a Tomcat4 script from /etc/rc.d/init.d so that Tomcat starts automatically? Tomcat works fine when I run startup.sh as root. However, common sense and many passing references on the mailing list suggest that root is not the best choice. - What user do people normally use? - Should I create a user for the purpose? - What attributes and permissions should it have? - Is this related to the tomcat tomcat element in the default tomcat-users.xml? I read somewhere that tar preserves file and directory permissions when unpacking .tar.gz files. However, everything now seems to be owned by root (group also root), possibly because I unpacked it as root. So when I run Tomcat as tomcat, it dies of 'access denied'. I have changed the owner and group to tomcat for the logs and conf directories (so that Tomcat can rewrite tomcat-users.xml ???) but I am very reluctant to do too much of this without fully understanding why and what the downstream consequences might be. Most things now work but not the admin application. - What is the best practiced with regard to permissions? Tomcat documentation seems to stop firmly at startup.sh and shutdown.sh (unless I simply have not found the right page). I have found FAQs and tutorials that give sample scripts for various Linux distributions (none so far for Fedora) but none of them work if the user and permissions are not good. - Can anyone please summarise what I need to do? Best practice, even? :-) - Should it be documented? - Would all this go away if there was an RPM? - Is there an RPM? :-) Many thanks Robin Rigby - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

The layout of 4.1.24 RPMs seams OK to me. There is a site, JPackage, I think, which has newer RPMs, but they have moved other packages from TC into separate ones (JavaMail, JDBC-ext,...), so getting it all together is not easy. Plus they have their own dependencies, which I couldn't provide on Mandrake. Nixie. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Tomcat does not die
Hello all I have a Tomcat 4.1 instaled in a Red Hat Linux 7.3 server. My JDK is JDK 1.3.0 from IBM. My Tomcat was instaled from a RPM package downloaded from jakarta project homepage. When it was installed, rpm created a file called tomcat4 in /etc/init.d. I use this script to start and stop my Tomcat. I have chosen that JDK because RPM package waits for JDK 1.3.0 from IBM. All works well. tomcat4 start starts Tomcat, tomcat4 stop stops Tomcat. But in some moments Tomcat stops responding (hang) then I try use the command tomcat4 stop to stop it but it does not work. Tomcat stops to listen his 8080 port but the processes (threads) stay still running (ps -ef). What can I do to solve this problem? Update Tomcat? Update JDK? Any help is welcome

RE: Cross site single sign on
Howdy, We have a standalone authentication web service used by all our apps. It's cookie-based. Yoav Shapira Millennium ChemInformatics -Original Message- From: Tim Funk [mailto:[EMAIL PROTECTED] Sent: Wednesday, December 03, 2003 6:54 AM To: Tomcat Users List Subject: Re: Cross site single sign on Sounds like pubcookie: http://pubcookie.org/ -Tim Will Hartung wrote: Hi all! Not necessarily Tomcat specific, but I'm curious what others may have done to support cross site single sign on. The basic problem is that customer goes to site A, and logs in. Then while navigating that site, they eventually head over to site B. Of course when they hit site B, the customer should already be logged in. If site A and site B live in the same domain space (say, site.com and b.site.com), then a site.com cookie should be able to be used as a token that show login. Of course, this requires cookies. It also requires both sites to maintain the cookie if the cookie is allowed to expire (say, it's only useful for 30 minutes). However I think this would have to be a signed cookie, where both participating servers encrypt to cookie with a known key (perhaps a shared public key). Now, if you have sitea.com and siteb.com, then the cookie technique can't work (as neither can set a cookie for the other). So, I'm thinking that you can do something similiar, a signed token, in a hidden field and then having to submit a form to get to the new site. Of course, you can always stick the token on the URL as well. Does that sum it up? Any other ways for cooperating sites to transparently exchange credentials? I suppose the back ends can do it. Send signed packets to each other during their log in processes to notify cooperating services. But if your logins time out, you still need to constantly update the session information. It's not enough to know that Bob signed in at 10am, and expires at 10:30. If Bob actively uses the site, you want the time out to be since last activity. How are others doing this and what have you found effective?

It's not completely irrelevant, but close ;) Do you have any 3rd party containers or such that live outside of the context (their JARs would be in CATALINA_HOME/server/lib or CATALINA_HOME/common/lib -- someone please confirm that the second of these two does *not* get discarded along with the rest of the context upon reload). I'll confirm that -- common classloader repositories (as well as shared and server) do not get discarded on webapp reload. They can't, as that might destroy other webapps.

It's not a problem with the tomcat classes. What you need to know is: - What 3rd party libraries does your application use - What classes stay in memory after a reload and have a 2nd instance of them created. You can use a profiler like Senor Hanik suggested (JProbe, OptimizeIt, etc.) to find out the latter. You want to look for a list of objects whose instance count increases after a reload of your webapp. OptimizeIt can do heap snapshot deltas which are the perfect tool here.

This is a common issue and has been discussed on this list many times in the past, though not for a couple of months. You can search the archives for more details. Yoav Shapira Millennium ChemInformatics -Original Message- From: Walter do Valle [mailto:[EMAIL PROTECTED] Sent: Wednesday, December 03, 2003 9:02 AM To: [EMAIL PROTECTED] Subject: Tomcat does not die Hello all I have a Tomcat 4.1 instaled in a Red Hat Linux 7.3 server. My JDK is JDK 1.3.0 from IBM. My Tomcat was instaled from a RPM package downloaded from jakarta project homepage. When it was installed, rpm created a file called tomcat4 in /etc/init.d. I use this script to start and stop my Tomcat. I have chosen that JDK because RPM package waits for JDK 1.3.0 from IBM. All works well. tomcat4 start starts Tomcat, tomcat4 stop stops Tomcat. But in some moments Tomcat stops responding (hang) then I try use the command tomcat4 stop to stop it but it does not work. Tomcat stops to listen his 8080 port but the processes (threads) stay still running (ps - ef). What can I do to solve this problem? Update Tomcat? Update JDK?

RE: Session not freed in tomcat4.0.6
Howdy, This is not a stupid question. The servlet specification mandates that sessions be persisted across server restarts. This is done so that if a user is doing something and the server crashes, the server can come back up with the user's session data intact. When the JVM is gone, all its objects ARE gone -- from memory. Session data by default is more like preferences that are persisted. This is of course tunable: you control the session timeout (in web.xml), as well as tomcat-specific session persistence settings. Read the Manager (component, not webapp) configuration reference for details.

I've debugged the servlet so I know it's getting to it and doing what I expect. In the original mail, Matt's servlet call is... - - - - - - - - - - - - - - - - - - - - - - - - - - String username = request.getParameter(j_username).toLowerCase(); String password = request.getParameter(j_password); ...

Aren't they somewhere in Struts? Do I really have to bring down all of that stuff?

tar problem resolved
Thanks Bill, That was indeed the issue, gnu tar restored the contents properly That bold message you refer to would have saved me hours p.s.

Re: Tomcat 4.0.x memory leak (not javac)
We first ran into this bug when hot-deploying JetSpeed - about seven times would cause an out of memory w/ the default heap size. JetSpeed had so many leaks itself that we dropped down to bares bones test app with a servlet, but no JSPs or third party libraries. With this small app would could do a hundred or so deploys or reloads before hitting out of memory. We purchased JProbe to try and further track down the problem. Unfortunately, JProbe appeared to disturb the environment enough that things could not clean up properly anyway. At that point we gave up the hunt. Although we're still using 4.1.x in production, we recently confirmed that the problem still exists in 5.x. In most cases we've been running RedHat 8 with a Sun 4.1 JDK, but we've seen the problem on Windows and MacOS as well. It is easy to reproduce - we used the Ant task to deploy inside a loop. No need to hit any pages or cause JSP's to compile, just redeploying will do it.

It's not a problem with the tomcat classes. What you need to know is: - What 3rd party libraries does your application use - What classes stay in memory after a reload and have a 2nd instance of them created. You can use a profiler like Senor Hanik suggested (JProbe, OptimizeIt, etc.) to find out the latter. You want to look for a list of objects whose instance count increases after a reload of your webapp. OptimizeIt can do heap snapshot deltas which are the perfect tool here.

Where is this mentioned in the release notes, and what would one have to search for? Under KNOWN ISSUES IN THIS RELEASE it does mention issues during web application reloading where shared libraries keep references to objects instantiated by the web application. That says memory leak to me although it doesn't specifically say that. 2. You mentioned in your passage the bug was marked as invalid or wontfix, and the bug you gave below is marked as new. So if anyone actually wasted time (like me) looking up what you said, they didn't find it. All I did was search for memory leak under Tomcat 4 and all status. I was not positive that it was marked WONTFIX, I should have clarified that in my original message. I had thought that the issue was something inherent to the design of Tomcat 4 (which was overhauled in Tomcat 5), but I'm sure that they are willing to accept patches if anyone can fix it. ;-) Bugzilla is obviously not working sometimes. I searched for memory leak one time and got it. Then I went to search for it for someone else so I could give them the bug number but nothing came up. I did the exact same search, memory leak. Very interesting indeed.

I also setup a demo application (JSPWiki) on a virtual host like this: server.xml Host name=doc.mteege.de address=192.168.18.184 Context path= docBase=/opt/tomcat/webapps/JSPWiki debug=0 / ApacheConfig forwardAll=true noRoot=false / /Host httpd.conf VirtualHost *:80 DocumentRoot /opt/tomcat/webapps/JSPWiki DirectoryIndex Wiki.jsp ServerName doc.mteege.de IfModule mod_jk.c JkMount /*.jsp ajp13 /IfModule /VirtualHost This works great and I try to setup another virtual host which serve the default tomcat index.jsp and the demo apps. server.xml Host name=cat.mteege.de address=192.168.18.184 Context path= docBase=webapps/ROOT debug=0 / ApacheConfig forwardAll=true noRoot=false / /Host httpd.conf VirtualHost *:80 DocumentRoot /opt/tomcat/webapps DirectoryIndex index.jsp ServerName cat.mteege.de IfModule mod_jk.c JkMount /*.jsp ajp13 /IfModule /VirtualHost I get the get the index.jsp but if I try to load the demo app folder I get a 404 error from tomcat. I think there is a mismatch between the apache DocumentRoot and the Tomcat docBase but If I use docBase=webapps I only get a indexview of the webapps folder. What do I missing?

I think Tim is right - he usually is - that there is a config problem with the db or the connection to the db.

RE: Global Variables
Howdy, Are you serious? ;) You might want to buy a servlets book or go through a tutorial, this is a very basic concept. You don't define a servlet context, the server creates one for you. You define context parameters in your deployment descriptor, the web.xml file.

Tomcat on Sun's Java Desktop System
Has anyone been involved with testing Sun's Java Desktop System? If you have, does Tomcat 4.1 run on it without any problems? According to Sun support JDS is based on SuSe 8.1 does anyone run Tomcat 4.1 on this platform and if so, what version of J2EE do you use?

RE: Tomcat does not die
I've experienced this using different VMs. Currently I have a site which serves nothing more than HTML...no jsp or anything, and this will happen every now and then. This occurs in all versions of Tomcat I have used. I'm running 5.0.x currently and it still happens. Wade -Original Message- From: Walter do Valle [mailto:[EMAIL PROTECTED] Sent: Wednesday, December 03, 2003 9:02 AM To: [EMAIL PROTECTED] Subject: Tomcat does not die Hello all I have a Tomcat 4.1 instaled in a Red Hat Linux 7.3 server. My JDK is JDK 1.3.0 from IBM. My Tomcat was instaled from a RPM package downloaded from jakarta project homepage. When it was installed, rpm created a file called tomcat4 in /etc/init.d. I use this script to start and stop my Tomcat. I have chosen that JDK because RPM package waits for JDK 1.3.0 from IBM. All works well. tomcat4 start starts Tomcat, tomcat4 stop stops Tomcat. But in some moments Tomcat stops responding (hang) then I try use the command tomcat4 stop to stop it but it does not work. Tomcat stops to listen his 8080 port but the processes (threads) stay still running (ps -ef). What can I do to solve this problem? Update Tomcat? Update JDK?
