2.2 Spec divergence?
Does anyone else think this is a divergence of Tomcat 3.2.1 from the 2.2 spec? In section 4.7 Temporary Working Directories it says: It is often useful for Application Developers to have a temporary working area on the local filesystem. All servlet containers must provide a private temporary directory per servlet context and make it available via the context attribute of javax.servlet.context.tempdir. The object associated with the attribute must be of type java.io.File. But in my experiments the File object returned by Tomcat 3.2.1 is not an existing directory. It appears to be a suggestion, e.g. should you want to make a temp directory, this would be a good place but it's up to me to use File.mkdirs() to actually create it. No big deal, but then File.mkdirs() isn't documented to succeed when the dir already exists, so in order to ensure portability to containers which may interpret the spec as saying return an existing directory ... I need to code something like File tmpdir = (File) ... if (! tmpdir.exists()) tmpdir.mkdirs(); and of course catch various exceptions. Just wondering if I missed something, or perhaps it's a bug fixed in a later 3.* version? Thanks, David Boyce
Tomcat/Netscape 3.6 connector for Solaris?
Does anyone know a location of documentation and/or binaries for the Tomcat-Netscape Enterprise 3.6 server? The http://jakarta.apache.org/tomcat/jakarta-tomcat/src/doc/tomcat-netscape-howt o.html document is completely NT-centric, to the point that it's not clear whether the redirector has been ported to Solaris or what it would be called if so. Considering the close relationship between Sun and Jakarta I'm surprised by what I seem to be seeing. I'm willing to RTFM if I can just find TFM. Thanks, David Boyce

This works in conjunction with a page, login.jsp, which has a form with fields j_username and j_password and action j_security_check. the final type is DIGEST, but i don't know if Tomcat supports this, as it is not required.

RE: Tomcat Init At Boot
The Tomcat logfiles are presumably not showing anything because the failure
happens before Tomcat starts up. Try adding the following line at the top of
your rc script:
exec /tmp/rc.out 21 set -x
And take a look at /tmp/rc.out after a reboot. You should see the failure.

Subject: Tomcat Init At Boot
I am currently using the binary versions of Tomcat 3.2.1 and JDK 1.3.0_02 on
Caldera eServer 2.3. I have placed a tomcat init script in the init.d
directory (see script below) and linked to in from the various rcx.d dirs.
My problem is that the script is being run during the boot sequence, but
Tomcat never starts. If I run the exact same script from the command line
(as root) however, Tomcat starts no problem. The log files aren't reporting
any noticeable errors when Tomcat fails to load at boot, so I am unsure what
the discrepancy is between init running the script and the root user running
the script. Any information or advice anyone can give me on this problem
will be greatly appreciated.

Tomcat and NT service via wrapper script?
Short version: I need to run Tomcat as a service on NT (and know how to do so) but need a hook to run an arbitrary command as part of the service startup. Details: I'm running Tomcat out of a ClearCase view (for those unfamiliar, ClearCase is a dynamic filesystem abstraction with a metalanguage allowing you to specify which versions of files you want to see, e.g. the state as of 3:34 PM yesterday or my changes but no one else's, etc. But note that my problem has nothing to do with ClearCase per se). Running in a view has many advantages, especially for development, as deployment (or rollback) becomes as simple as changing a line of metalanguage to select newer (or older) versions. However, the use of ClearCase is a red herring; the only concern is that the view must be started with the command cleartool startview view-name before Tomcat runs. I'm doing this on UNIX now and it works just great with a little bit of scripting. But I now need to do the same thing on Windows; unfortunately the whole service business there seems pretty intractable. All I need is a hook to run the startview command prior to Tomcat startup but I haven't been able to dig up documentation on how or whether it can be done. To save time let me enumerate what I don't need: I know how to run Tomcat as a service on NT and have done so successfully. I'm aware of the JDK 1.3.0 bug which affects this. I realize that ClearCase (which also runs as a service on NT) must be started prior to Tomcat and have read up on how to edit service dependencies in the registry. All I still need is a way to run an arbitrary command (which happens in my case to be cleartool startview) as part of the service startup sequence. Has anyone done something similar? Thanks in advance, David Boyce
RE: Tomcat and NT service via wrapper script?
Keith, Thanks, I also considered that one for a while previously before realizing its fatal flaw. The way ClearCase works, starting a view is analogous to mounting a filesystem. Thus the wrapper.properties file (as well as all the other config files, classes, etc.) aren't present till the view starts so there's a catch-22. It comes back to how to run the equivalent of this two-line script: some.random.program tomcat start(or alternatively java org.apache) as a service. I don't have MSVC or MSDN so am sort of handcuffed in terms of research but it looks as if the jk_nt_service.exe is written to assume the thing it's managing is a java program, Likewise with JavaService and javaserv. Does anyone know why it's not possible (apparently) to run a script as a service? Why does the service installer/manager/whatever it's called need to know what kind of program the service cmd is? I realize this is drifting away from Tomcat proper so I'll take it somewhere else after this attempt. David Boyce -Original Message- From: Keith Gross [mailto:[EMAIL PROTECTED]] Sent: Tuesday, April 24, 2001 5:47 PM To: [EMAIL PROTECTED] Subject: Re: Tomcat and NT service via wrapper script? I haven't done what you're looking to do but I did do a lot of research on the NT service wrapper for Tomcat while trying to overcome the user logoff problem that JDK 1.3.0 has. I can see one promising possibility. The service wrapper uses the wrapper.properties file in the conf sub-directory to form a command line that is used to launch Tomcat in a separate process. You can see the commandline in the last line of the file. You could possibly rewrite the command line to instead run the command processor (cmd.exe) with a batch file that would run your command and than start Tomcat. I'm at home and most of my research was done at work so if you have questions or problems post them and I'll consult my notes at work. Any number problems could come up with this arrangement. 1). The way the service wrapper launches the sub-process might prevent the command processor from being launched as desired. 2). The context your running in (i.e. as a service and under the system account) might make interacting with ClearCase difficult. Pathing and security are the two most likely issues here. 3). If the ClearCase command takes to long it will causes the service manager to think the service has failed and shut things down.

macro expansion in server.xml?
I have an intranet web app which must run on perhaps a couple of dozen widely distributed Tomcat containers; some on Solaris, some Windows NT, maybe Linux and AIX later. In this situation the toughest challenge isn't writing the web app per se but in maintaining the many containers, tweaking server.xml et al manually for each. I've been experimenting with using a Network Appliance (a fileserver that can serve UNIX via NFS and Windows via SMB) to hold a single physical copy of Tomcat such that all these containers are running from a single pile of bits. This is actually working quite nicely so far except for a little holdup - they all want to write their logfiles to the same place. So I'm wondering if there's a way to put logfiles in, say, $TOMCAT_HOME/$HOSTNAME or otherwise indirect through a macro/property besides TOMCAT_HOME. I've tried setting the log paths in server.xml to absolute pathnames e.g. /var/log/tomcat/... which works on UNIX but not Windows. Same for C:/log in reverse; it has to be a relative path for interop reasons. Does anybody have successful experience or ideas in this area? Thanks, David Boyce
