Parameter value based on server
Hi
I want a parameter such as the following:
<Parameter name="companyName" value="My Company, Incorporated"
override="false"/>
to have different values on different tomcat servers. Say 3 applications on 2 different tomcat boxes, all of which will use element companyName. However, companyName will be different on the two boxes.
I thought of putting this in the context.xml or web.xml file.
However, my understanding is that these files are used by Servlets only?
I have a "helper class" that will need different name,value pairs on different boxes.
What solutions are available? What solutions should I investigate?

along that recommendation an axis2 examples
web.xml
<web-app>
<servlet>
<servlet-name>AxisServlet</servlet-name>
<display-name>Apache-Axis Servlet</display-name>
<servlet-class>org.apache.axis2.transport.http.AxisServlet</servlet-class>
<param-name>axis2.xml.path</param-name>
then axis2.xml uses parameter
<axisconfig name="AxisJava2.0">
<parameter name="hotdeployment">true</parameter>

If you set a system property via -DcompanyName="My Company, Incorporated",
then you can do:
<Parameter name="companyName" value="${companyName}" override="false" />
Tomcat will expand the ${companyName} to the value of the system property
when it parses the xml file. And, no, the property name doesn't have to be
the same as the Parameter name.
This is a Tomcat feature, but since you are putting it in a Tomcat
configuration file, I'm going to guess that that won't bother you.

They're available to any code that has access to ServletContext, which means pretty much any code you have in the webapp.

If the values are global for all webapps in a given Tomcat instance, you could set an environment variable or Java system property to hold the name, and retrieve it via System.getenv() or System.getProperty(), respectively.
