Re: Database pooling prob
What did you specify for the ip address that tomcat uses for connecting to the database? If, for example, tomcat is using the host name of your machine, or its ip address that you'd use to connect to it from the outside, and psql is using localhost (127.0.0.1) which is a special ip address that always goes to the machine you're on, so that you don't have to know its ip address, that would be a difference in the configuration. Or psql could be using a unix filesystem socket and not using tcp/ip. Postgres uses some config file with hba in its name to configure its network security; fiddle with that and make it wide open so that tomcat can connect, then go back and figure out how to tighten its security so that only localhost can connect.

Re: tomcat startup
As a workaround/kludge, could you have your tomcat startup scripts use the database command line tool to query the database and if it fails or doesn't return something reasonable, have it in a loop that sleeps for 5 or so seconds and then tries again? Nathan Aaron wrote: I am using Tomcat 6.0.18 and jdk1.6.0_12. I apologize for not posting that in the beginning. I deploy several applications using one instance of Tomcat. The Application uses a database that resides on a separate server. When these servers are rebooted I would prefer that Tomcat start on server A. Then on server B, the database startup script can just make a call to start the context. If I don't do it this way Tomcat will start and start all the contexts.

I tried setting autoDeploy to false as well, restarted Tomcat, and then nothing deployed - ever. Nor could I figure out a way to deploy anything manually, since the manager webapp wasn't deployed (catch-22). One way around this is to keep your webapps in some directory other than the one pointed to by the Host appBase and deploy them by placing a Context element with the appropriate docBase setting in conf/Catalina/[host]/[appName].xml when you want the associated webapp to start. Your Tomcat shutdown script would then remove all such files to prevent their automatic redeployment on the next Tomcat startup.

Re: Parameterizing log4j.properties/xml files
I was doing something like this with LogBack (successor to log4j more or less),
but I'm no longer using it and don't remember how I set it up. The class
starts as follows:
public final class InitLogback extends HttpServlet {
@Override
public void init() {
final String pathPrefix = getServletContext().getRealPath(/);
And I think pathPrefix then contains the name of the directory in the tomcat
webapps folder.
I don't remember how I was configuring this servlet in the web.xml file;
possibly as a regular servlet with a load-on-startup value that was lower than
the main (Spring) servlet.
I don't claim that this is the best way to accomplish this.
If you're using Spring you may want to look at its
org.springframework.web.util.Log4jWebConfigurer
and
org.springframework.web.util.Log4jConfigListener

That's easy.
I'm going to be using log4j, probably with properties files, but xml

I'd like to have log files named mylog.log appear in
${catalina.home}/logs looking like
myapp1-mylog.logmyapp2-mylog.log... etc.
I could hardwire this in separte log4j.properties files for each myapp

log4j.appender.myLogFile.File=${catalina.home}/logs/myapp1-mylog.log
log4j.appender.myLogFile.File=${catalina.home}/logs/myapp2-mylog.log
And using ant to build my war files, I could hide this ugliness, just
copying such hardwired files into the war being built.
But is there any parameter syntax that would allow me to grab the

There is a fairly heavy amount of files uploaded from many different users so it would mean a lot of configuration and a lot of maintenance to that config as i add new users. So I am trying to avoid the operating system chmod commands in my code. I don't really like that either, and it does break if you ever (yuk) would decide to run your code on some other platform. If i add umask 002 in my ./etc/init.d/tomcat start up script it seems to fix the problem but i think this is setting that umask for more than just tomcat so i am not sure how safe that is. As far as I can tell, it would only change the umask for the current process (the shell executing your startup script) and all its offsprings (jsvc, tomcat). But it will do it for *everything* that these processes do (such as creating temporary files, logfiles, etc..). That may indeed not be very secure. For instance, one thing which Tomcat to my knowledge does (if you have not disabled it) is to rewrite the conf/users.xml file each time it starts up (or stops ?). That particular file is not essential, and maybe Tomcat does not do that anymore in recent versions, but there might be other such things lurking around unexpectedly. That was my concern, I think it is a very mild security concern but still an issue nonetheless. Since the tomcat user doesn't have shell access or root access I can't see it being a big issue, it would be nice if you could set the umask for just the class loader or running java process. I'm still a bit curious about how you did organise the upload directories and their rights and groups etc.. finally, because you want this one Tomcat user to be able to write into upload directories owned originally by other users, right ? Or at least, you want these other users afterward to have access to these files somehow. So you must have established some common group or groups between the Tomcat user, and these other users, right ? I am just wondering if by doing this, you have not weakened the general protection of all that stuff. You got it. Here is how i have it set up let me know what you think: I created a shared group : groupadd sharedgroup Then i changed it so all my users were members of this group: usermod -g sharedgroup tomcat usermod -g sharedgroup jaileduser1 usermod -g sharedgroup jaileduser2 ...etc Then I found some settings in the jailkit ( http://olivier.sessink.nl/jailkit/ ) that allow for the jailed users to have group read/write permissions: in /etc/jailkist/jk_chrootsh.ini relax_home_group=1 relax_home_group_permissions=1 relax_home_other_permissions=1 Then in the jail jk_lsh.ini i set up the umask for the shared group: [group sharedgroup] paths= /usr/bin, /usr/lib/ executables= /usr/bin/scp, /usr/libexec/openssh/sftp-server umask= 002 Finally I added the umask 002 line to my tomcat startup script The external jailed users only have sftp access and aren't able to move outside their home directories. Since the jailed user shares a group with tomcat they can all incestially read and write files to these home directories and since the umask is set the permissions are retained as new directories are created and so forth. What do you think? I had a quite similar case to resolve not so long ago (with Apache, not Tomcat), and only ended up with ACLs after being forced to use them, because no other solution would really provide the security I wanted.

So if you had the sed command s/(a)+/z/ and you fed it the string aaa, you would not get back z. You'd only get back z if you fed it the string (a)+. These old regexps of the ed lineage also didn't use the newfangled + notation; you had to list how many you wanted to match, or zero or more; a* would match zero or more, aa* would match one or more, etc. André Warnier wrote: Rusty Wright wrote: [...] The \( \) is the grouping thing where what matches in it is then substituted for as the \1 on the right hand side.

Re: [OT] run tomcat as tomcat user
Thanks; good point about the speedup by not using .* (although since this is in
a boot script, in this case it shouldn't really matter much). The \( \) is the
grouping thing where what matches in it is then substituted for as the \1 on
the right hand side. Cut is one of those commands I never remember to use,
same with xargs.

Yes. That alone will probably make you regexp about 10,000 times

backtrack one character and try again.
When it has found the last :, it will fail to match with the next
.*, so it will backtrack.
And so on...
I don't think 10,000 does it justice. ;-)
I also don't think you want to escape the ().
On the other hand, I think cut might be your friend here.

Re: run tomcat as tomcat user
To answer my own question; I did some google searching and figured out that you
need to copy the tomcat conf directory to ~tomcat and also create the
directories ~/tomcat/logs, ~/tomcat/temp, and ~/tomcat/work; all owned by
tomcat. Then copy over the webapps directory, or make a new one in ~tomcat and
copy over the wars.
So my ~tomcat looks like the following:

Re: run tomcat as tomcat user
(Repeating a reply I sent a week or so ago.)
I made this by modifying one for a different service.
It's set up so that tomcat runs as the user tomcat. In order to do that you'll
need to tweak the ownership of the files in the tomcat directory. I just made
everything owned by tomcat except webapps, which I own, but which is group
owned and writable by tomcat so it can explode the wars.
I'm on ubuntu (notice the two flavors of the functions file it sources).
You may not need the HUDSON_HOME stuff and I'm sure you won't need the
Dwaitlistd.host=${HOST} so delete stuff as necessary.
If you want it to run as root I'm guessing that you'd need to delete the
--chuid and --user lines.

Re: PostgreSQL vs MySQL with Tomcat
It's a rewrite of an app I did awhile ago in php. I think the biggest gripe I've had with mysql is the problem where I was violating a unique constraint and it was giving me some generic (completely useless) error; HY001 I think. In various ways, which I can't articulate, MySQL just feels to me more amateurish compared to PostgreSQL. With MySQL things are changed on an apparently ad-hoc basis and I've heard that they've broken backwards compatibility more than once. I realize that SQL isn't exactly the most widely adhered to standard, but MySQL seems to be more divergent than [most of] the others. When I had that HYwhatever error, I was completely stumped, so in order to troubleshoot it I copied the database to an MS SQL Server that I'd been using for something else. I remember having read somewhere that SQL Server is reasonably close to the SQL standard and I was amazed at how much work it took to translate my ddl and sql from MySQL to SQL Server. (Apache DdlUtils and Hibernate could have helped with the ddl.) I can't remember all of the various problems I've had with MySQL but here's one that seems typical; I started using it back when it was (or at least it seemed to me) more typical to edit user permissions by updating the mysql.users table, rather than using the GRANT command. So I have these various sql files that insert stuff in the mysql.users, mysql.db, and mysql.hosts tables and they have lots of 'y' and 'n' entries. At some point they changed things and they had to be uppercase. Previously I think they converted them to Y and N, but suddenly a newer version accepted the lower case with no complaints but didn't convert them, and they didn't work (it was as if the ys were Ns); I could have been inserting any random letter or digit apparently. That took some head scratching to figure out. I had forgotten that Sun bought MySQL so it should be interesting to see how that plays out. I heard that they're doing a major rewrite, starting from scratch, but going to keep it backwards compatible.

Re: PostgreSQL vs MySQL with Tomcat
That may be true about the public schema being used when one isn't specified. But when I use their pgAdmin gui tool and open the query window and try to run the tiger sample from the Jailer tutorial it blows up on the table creates, saying: ERROR: no schema has been selected to create in ** Error ** ERROR: no schema has been selected to create in SQL state: 3F000 I wonder if iBatis is adding the public schema automatically for you? Or maybe when I set up my db account I didn't do something I should have? Or I changed something and don't remember. And you've prompted me to remember another reason why I thought schemas are required. When our DBA set up PostgreSQL he didn't do much tweaking and the public schema had odd permissions; if I remember correctly it allowed me to create tables in the databases of other users in their public schema. I didn't try dropping their tables in their public schema but it may have allowed that as well. On my test db the sql for the public schema is CREATE SCHEMA public AUTHORIZATION postgres; GRANT ALL ON SCHEMA public TO postgres; COMMENT ON SCHEMA public IS 'Standard public schema'; Just after I installed postgres it had another grant line which I think was (or similar to) GRANT ALL ON SCHEMA public TO public; which I deleted (and in my usual boneheaded fashion, forgot to document my change, but it's my personal test database).

Christopher Schultz wrote: -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Ken, Ken Bowen wrote: Unfortunately, MySQL isn't really that tunable.

There are /some/ things you can tune, but not much. It's like an auto-adjusting clutch. Sure, you can adjust it, but it's going to do a pretty good job on its own. I created a couple of proof-of-concept projects with PostgreSQL for someone about six months ago, and the only really puzzling thing what how to set up sequences corresponding to MySQL's AUTOINCREMENT (I'm not sure I've really wrapped head around it completely anyway). For those small projects, it worked well, but there was no stress involved. I have no experience with PostgreSQL, but I was always irritated by lack of support (in previous JDBC specifications) for the AUTOINCREMENT fields (fixed, of course, in JDBC 1.4 when Statement.getGeneratedKeys was added). Oracle-style SEQUENCES always made more sense to me -- although they require an additional query to be issued every time you want a new id, you can use them for anything; not just record PKs. I think PostgreSQL has Oracle-style sequences. There are no auto-incrementing PKs or anything like that: you first SELECT the next value from the sequence, then use that as the PK for your INSERT that you issue immediately afterward. If you don't need to capture the new id from the code, you could probably even do this: INSERT INTO my_table (id, ...) VALUES ((SELECT next FROM my_sequence), ...) I have no idea if that would even work. Give it a try! I'd like to hear about people's experiences and what they think are the strengths and weaknesses of each DBMS for use behind Tomcat. MySQL has always had super good performance for me, especially using MyISAM tables. The addition of InnoDB tables was great because you got the relatively fast speed of MySQL (compared to, say, Oracle) with the integrity you really expect from a production-quality RDBMS. Since I'm not a DBA, I'm appreciated the fact that MySQL can often be a fire-and-forget kind of service. It just doesn't need much care and feeding. I remember my first job out of college required new engineering hires to go through their one-box-wonder runbooks to make sure we understood how installs went and how the pieces fit together. Installing Apache Jserv (yeah!), httpd, and most everything else took about one or two printed pages of documentation. The rest of the runbook was Oracle install and configuration. Install. Run the command-line tool. Quit the command-line tool. Edit a config file. Re-run the command-line tool. Create the database. Quit the command-line tool. Change the rollback segment size. Etc. etc. etc. I never even understood anything I was doing, and neither did the folks that were supervising our execution of these tasks. These were just instructions that probably worked for someone in the past, so they wrote them down and nobody ever bothered to figure out if there were any better options. I was one of the first engineers who used MySQL in a project that went to production (and I had to implement my own pre-innodb manual rollback logic -- yikes!). MySQL supports a lot of functions that are, of course, outside the SQL standard, but are nonetheless useful.

I've found MySQL's error messages particularly worthless in some situations; I had a foreign constraint and it was giving me some generic error when I was violating that foreign constraint. Say MySQL around our DBA and steam starts coming out of his ears. The one warning I can think of with PostgreSQL is that you have to use schemas; you either have to set the schema after you connect, and I think I couldn't figure out how to do that with jdbc, or you specify it as part of every table name; create table schema_name.table_name ...; select whatever from schema_name.table_name;.

Re: single instance of background job?
That's exactly how it is now; it's on what's called our app server which is a single machine. The problem with our app server is that the developers aren't allowed access to it; the software is updated and installed by our production control/release management team. So, for example, if I need to look at the log files, I have to ask them to send me a zip file of the logs directory. If I need to tweak its configuration then I make a new release and schedule a deployment with them; so something as trivial as changing its crontab requires a new deployment. And the app server is forbidden to run tomcat or a web server. The reason making it a web app appeals to me is that then I can have it log to a database, and I can tweak its configuration via a web page. And I can have a checkbox, disable/enable so I can turn it off if needed. What adds to the difficulty of it is that the cron job is interacting with an IBM mainframe, uploading file with ftp and there's no real test instance of the mainframe side so testing is really scary (it's a legacy billing system so money is involved).

Re: Linux Runtime Script
I made this by modifying one for a different service.
It's set up so that tomcat runs as the user tomcat. In order to do that you'll
need to tweak the ownership of the files in the tomcat directory. I just made
everything owned by tomcat except webapps, which I own, but which is group
owned and writable by tomcat so it can explode the wars.
I'm on ubuntu (notice the two flavors of the functions file it sources).
You may not need the HUDSON_HOME stuff and I'm sure you won't need the
Dwaitlistd.host=${HOST} so delete stuff as necessary.
If you want it to run as root I'm guessing that you'd need to delete the
--chuid and --user lines.

Re: Logging configuration in Tomcat
If you're looking for a way to have a central log4j file for all apps, that may not be easily done. I don't know how it is now, but I remember that in previous versions of tomcat sharing tomcat's logging was problematic, which I think may have been due to Commons Logging. But that's just my hot air; I'm no tomcat expert like the others here. No matter how much you may think it's a good idea now, I'll bet you that in the future you'll regret it when you're problem solving and need to tweak one app's logging. Having all of your apps joined at the hips with respect to logging just sounds like something that will cause unforseen problems later on. Jay wrote: OS : RedHat Linux Tomcat version : 5.5.20 Am able to configure the logging level at individual war files, by referring to log4j.properties in web.xml.

Re: Setting /WebContent as ROOT for an application
To add to what Alan said: If I create a new Eclipse Dynamic Web Project, and name it MyWebApp during the project setup, in the first window it has a drop down for Target Runtime. That should be your installed Tomcat on your desktop development machine; Windows in my case. It starts out with None so click the New button next to it and select, for example, Apache Tomcat v6.0, and then in the next window use the Browse button to navigate to where Tomcat is installed (C:\Program Files\Apache Software Foundation\apache-tomcat-v.0.18 for me). You can leave the rest alone and click Finish. Next in Eclipse, do Window - Show View - Servers. That creates a Servers view window (tab) somewhere. Click on its tab to bring it forward, then right click in the Servers window and select New - Server (strange that we have to do this again, but at least it's abbreviated this time), and select Tomcat v6.0 Server (or whatever you selected when you created the project). Then you get the Add and Remove Projects window; double click on MyWebApp to move it to the right into Configured projects, and click Finish. As per the DOS tree command my Eclipse project folder/file structure is then | .classpath | .project | +---.settings | .jsdtscope | org.eclipse.jdt.core.prefs | org.eclipse.jst.common.project.facet.core.prefs | org.eclipse.wst.common.component | org.eclipse.wst.common.project.facet.core.xml | org.eclipse.wst.jsdt.ui.superType.container | org.eclipse.wst.jsdt.ui.superType.name | +---build | \---classes +---src \---WebContent +---META-INF | MANIFEST.MF | \---WEB-INF | web.xml | \---lib You can ignore .classpath, .project, and .settings. If you check your project into Subversion, I recommend telling it to ignore those files; some people prefer checking them in. I completely ignore the contents of the build folder; whenever you do a clean in Eclipse it wipes and removes that folder. The folder of interest for me is the WebContent folder; its layout and contents is what will ultimately be in Tomcat as /usr/local/tomcat/webapps/MyWebApp (sorry, switching to Unix parlance there). This means that any jar files your project needs go in WebContent/WEB-INF/lib. Also, you should create the folder WebContent/WEB-INF/classes and put in it those things that need to be on the classpath, for example, your logging config file (e.g., logback.xml or log4j.xml, or log4j.properties if you prefer that confusing format), and any other properties files and whatnot. It's instructive to do as Alan says and do the Eclipse export to war and then list the war file with a zip program to see what it's going to look like when Tomcat explodes it. Static jsp files will go directly in the WebContent folder (e.g., index.jsp). Dynamic jsp files will probably go in some subdirectory of WEB-INF; for example, I use Spring and I've configured it to look for the views in WEB-INF/views/jsp, with even more folders in that if I'm using something like Tiles. Back in Eclipse, in the Servers tab/window, is an entry for Tomcat, and the controls for that are at the top of the tab; the green circle arrow starts Tomcat and when it's started the red square stops it. In theory, and perhaps in practice, you can edit your .java files and do a compile/build in Eclipse and Tomcat will automatically reload them. I'm superstitious from back in the day when that didn't always work and try to remember to stop Tomcat before I do a build. This implies that I have Eclipse configured to not automatically build when I do a Save on a file. If Tomcat does get wedged in Eclipse; for example, changes stop showing, you can simply delete the Tomcat instance from Eclipse by right clicking on it in the Servers window/tab and selecting Delete, then re-add it and add your project to it. Note that when you start and run Tomcat from within Eclipse it's not deploying your project to your installed Tomcat; it's using the installed Tomcat's jar files and copying/creating its own Tomcat configuration files into your project space and running it all in there. It's all rather magical and, surprisingly, given all the apparent black magic, works quite nicely. It gets even more black magical if you use Maven and use the m2eclipse Maven plugin for Eclipse, but I think it's really worth it to climb that mountain because it gives you a great base for a consistent and maintainable project structure. Alan Chaney wrote: In Eclipse, assuming you have the WTP tools installed, you create a 'Dynamic Web Project.' This has a folder structure of which the essence is: MyApp src com mypackage Abc.java build com mypackage Abc.class WebContent index.html (or jsp or whatever) WEB-INF web.xml

Re: tomcat ROOT
Not naive at all; I think it's an entirely relevant and obvious question. In my situation we have a system that's administered by a different group than mine (we're merely application programmers) and the system administrators have settled on doing things this way. They're understaffed and overworked so having a common setup for everyone on this shared system seems reasonable to me.

Sorry, I thought I did. It has nothing to do with tomcat; it's up to the browser whether or not it assigns different sessions to the tabs or not. Apparently IE, or some versions of IE, do. In my experience Firefox doesn't. I think if you have multiple Firefoxes opened, i.e., separate windows, not just separate tabs, they still share the session.
