RE: Tomcat reboot runtime
The script will need to be a 2 stage process otherwise the kill tomcat command will kill your shell as part of its shutdown sequence and the rest of your script will not execute (no restart). Stage 1. - start disconnected sub shell for process 2 Stage 2. - kill tomcat, sleep, start tomcat In most UNIX shell these is a nohup command that disconnects the shell for daemon processing that should work. You can either script both parts or build the correct nohup shell and do stage 2 from java. -Original Message- From: Shapira, Yoav [mailto:[EMAIL PROTECTED] Sent: Thursday, May 13, 2004 9:02 AM To: Tomcat Users List Subject: RE: Tomcat reboot runtime Hi, What's running your program (in order to wait and issue a startup command) after you've done a shutdown? ;) (Unless you're talking about highly tomcat-specific code that shuts down tomcat and leaves the JVM itself running) Yoav Shapira Millennium Research Informatics -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Thursday, May 13, 2004 11:55 AM To: Tomcat Users List Subject: RE: Tomcat reboot runtime Personally, I don't see why the scheme that Adam came up with wouldn't work.

JDBC Source getting null url
I just started to
try and use a database source for some of my pages in my web app and am not
getting a connection. I am using Tomcat 5.0.19 with JRE 1.4.2_04 on redhat
9 with mysql. Every time I try to connect I get a exception saying
Datasource invalid, not suitable driver for class '' url null (actual error page
attached). I am trying the examples in the docs, I get the same error in
either servlet or jsp page, I have included the jsp page. I have
everything packaged in the web.xml file of the application to try and keep it
portable. I also tried using the admin tool and register a global data
source and get the same result.
If I mistype the
datasource name in the jsp it says it cannot find it so I does find some of it
to verify, but why does it not find the resource parameters providing the driver
and url? I tried to google for some answers, but did not find much that
applied to the same versions.
Thanks in
advance.

I also tried it using a global resource (option 1) with the same error result. Built it by hand and used the admin pages, same result. Since I do not have a context entry for my app I will try to build one and see if option 2 works. -Original Message- From: Sasha Borodin [mailto:[EMAIL PROTECTED] Sent: Monday, May 10, 2004 2:30 PM To: Tomcat Users List Subject: Re: JDBC Source getting null url Richard, I believe the first two elements appearing in your web.xml (Resource and ResourceParams) need to be present in the server configuration: 1. either as a global resource in your server.xml (inside the Server element) 2. or as a context specific resource in a context descriptor - a Context entry in your server.xml, or (the new way) an external xml file (http://jakarta.apache.org/tomcat/tomcat-5.0-doc/config/context.html) This way Tomcat knows about and sets up the resource for you web application to use; I think the only thing you should do in your web.xml is declare a need for a resource, though this part I'm hazy on, as my stuff has always worked without any mention of the container-managed resource in my web.xml's.

RE: JDBC Source getting null url
Ok, option 2 worked. If I placed the resource and resourceparams in the context it worked. I used the tomcat5 version and modified the web app default standalone context xml file. I would like to still understand why the global one did not work or declaring it in the web.xml file. -Original Message- From: Richard Calosso [mailto:[EMAIL PROTECTED] Sent: Monday, May 10, 2004 3:32 PM To: 'Tomcat Users List' Subject: RE: JDBC Source getting null url I also tried it using a global resource (option 1) with the same error result.
