How to configure in Tomcat?

[Xi Chen <ro...@gmail.com>]

Hi, there.  I have a question in my deployment under Tomcat 5.5.

In one of the java classes I wrote, I have a line of code like the following:

      String propertiesFilePath = System.getEnv("MY_CONFIG_FILE_PATH");

       //  Then I start load the contents of the file into java Properties.


I set up the environment variable (MY_CONFIG_FILE_PATH) correctly on
the machine, and the class function all right if I test it via a
command line.

However, if I test the class under Tomcat (after deploy the class to
the appropriate path under Tomact) on the same machine, it complains
that it cannot find the path.

Given that result, I speculate that Tomcat has no way to know the
environment variables. Am I wrong?   Is there anyway to configure
Tomact (e.g. setting a config variable like "MY_CONFIG_FILE_PATH"
under Tomcat), so that all the deployed knows the value of the
"MY_CONFIG_FILE_PATH".

All I want to achieve is that:

   Put all the needed SQL queries in a properties file and let java
classes retrieve the queries from the properties file (in stead of
using hard-coded queries in the source code).

It seems to me to deploy the properties file under the Tomcat is a bit
challenging.

Any guidance will be highly appreciated!

[foo shyn <fo...@optegra.com.my>]

It shouldn't be a problem for application to get system properties....tried
that before and it worked fine for me...

Is ur path a full path ? i mean is it something like "C:\......" or is it
just started with a slash like "\......"?

If it's started with a "\..." u need to put the specific file and the
folder(s) that contains it in the Tomcat folder, otherwise it should be
working fine...

my 2 cents, and hope it helps.
