Reading environment variable from Tomcat
Hi, I have run into an issue related to starting tomcat as a service. When we were starting tomcat from the command line, we were able to just say System.getProperty(user.name ) to retrieve the logged in user id. But now that we start tomcat using a service, the get property call returns SYSTEM. After doing some more research, it seems like I have two options to find out the login id. 1. Start the service using logged on option. 2. Use System.getEnv() It seems like the first option may not work for us as our passwords expires periodically, and setting the logon/password account means that we would have to have manual intervention. Additionally, when I tried use my user id as logon id, it won't let me do that ( I imagine I need to have system admin turn the privilege on for or something on those lines) The second option did not work either. Calling the System.getEnv(USERNAME) in a program started from the command line returns the logged in user name, but it returns null when tomcat was started using service approach. I am not sure if there is a way to find out who is logged in into the system when Tomcat has been started using service mechanism. Any help in this matter would be great help SS
RE: Reading environment variable from Tomcat
The service does not need to run when no one is logged in. We are in a kind of one off situation where Tomcat would be running on standalone laptops when the users are not connected to internet. So we are not running it on windows server rather on windows xp. I saw the other reply but I am not sure if I understand how to make that work. I just tried the option of adding --User in the service.bat specifying my user id, but it did not work. Also as I mentioned in my original email, the password issue will remain as a problem even if we get past the first issue.

RE: Reading environment variable from Tomcat
Because we are using the app more like a standalone application (for details please see my another posting). Generally these sort of app are not meant for tomcat, but we already had the app developed for central server, and we had a need to run the same app in a standalone mode for folks who are not connected to internet. Hence we took the same code base (with lot less fat) and ported it on tomcat. -Original Message- From: David Smith [mailto:[EMAIL PROTECTED] Sent: Wednesday, August 13, 2008 1:47 PM To: Tomcat Users List Subject: Re: Reading environment variable from Tomcat Looks like correct behavior to me. You can see that tomcat runs in the System account when you look at it via Process Explorer or Task Manager. It has it's own environment separate from any desktop user and can run without any desktop user. This is also why tomcat can't access mapped network drives when it runs as a service. The real question is why do you want to know who the current desktop user(s) is/are? Tomcat should only be interested in the users coming in via http(s) connections. --David Sureka, Sushil wrote: Hi, I have run into an issue related to starting tomcat as a service.

Defining JDBC Data source
We are trying to port an application from Weblogic to Tomcat. Our JDBC entry looks like this bean id=the_dataSource class=org.springframework.jndi.JndiObjectFactoryBean property name=jndiName value=myJDBC / /bean The weblogic works fine with setup. The jdbc datasource is setup through weblogic console. On Tomcat, we noticed that we would have to modify the above entry like this bean id=the_dataSource class=org.springframework.jndi.JndiObjectFactoryBean property name=jndiName value=java:/comp/env/myJDBC / /bean But the above setup won't work for Weblogic. Any way we can reconcile the difference. The Tomcat context.xml file contains an entry llike Context Resource name=myJDBC auth=container ./ /context Sushil
Tomcat installation/deployment question
Hi, We are intending to deploy our application on individual laptops (to be used by field personnel who does not have internet connectivity to connect to our central server). The idea is that a trimmed down version of our core application will be deployed on individual laptops running tomcat against a light weight Sybase database. I wanted to see if you had any suggestions about - 1. How best to deploy the initial version (5.5) of Tomcat on individual machines - We understand our options are Microsoft SMS, Java Web Start application, shell script or Ant script to install Tomcat on these laptop boxes. We are leaning towards Microsoft SMS since (a) It can easily mass deploy the app to hundreds of machine (b) It is currently used in our organization to deploy some asp application. If you believe there are downsides to this approach or other approaches are better please let me know 2. How best to deploy the upgraded version (6.x or higher) - We potentially could use the same approach as the first one, but wanted to see if the opinion differs. 3. And finally the rollout of initial app and upgraded app version. Again probably use the same approach as before but wanted to throw this out there in case there are better ideas. Please let me know your thoughts on this. Sushil

RE: Tomcat installation/deployment question
Martin, thanks for the advise. We are already decided to move forward
with the decision to deploy on individual laptops. So yes we will have
sufficient hardware on laptop.
The question, what is the best way to put the tomcat installation and
upgrades, application installation and upgrades on the server. In other
words, question is not if, but how

you can install a server product (2003) on a laptop which has
the requisite chip characteristics/sufficient ram
(4gb)/sufficient diskspace(.25 tera) and sufficient
clockspeed (in other words server hardware characteristics)
to support that server
Databases:
You can configure your connection-string to point to the
remote DB server and remote DBname which has a DBlistener
installed e.g.
private static Driver c_Driver = null;
private static final String c_sDefaultDriverName =
oracle.jdbc.driver.OracleDriver,
private static final String c_sDefaultDBURL =
jdbc:oracle:thin:@host:Port:DBName,
try {
c_Driver = (Driver)Class.forName(
c_sDriverName ).newInstance();
}
catch ( ClassNotFoundException cex )
{
}
//set your properties here and then connect with the provided
URL connection-string
c_Driver.connect( c_sDBURL, props );
