RE: Environment variables

[I-Sampige, Srinivas]

Be very careful how you put those parameters in the web.xml file. Here is a working 
sample -


<?xml version="1.0" encoding="ISO-8859-1"?>

<!DOCTYPE web-app
    PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.2//EN"
    "http://java.sun.com/j2ee/dtds/web-app_2.2.dtd";>

<web-app>
  <display-name>Apache-Axis</display-name>

  <!-- initialization parameters for all web services/web apps deployed in this 
context. -->

  <!-- the demo .fo file for the FOP Web Service-->
  <context-param>
    <param-name>fop_demoFoFileName</param-name>
    <param-value>demo.fo</param-value>
    <description>foo desc</description>
  </context-param>

  <servlet>
    <servlet-name>AxisServlet</servlet-name>
    <display-name>Apache-Axis Servlet</display-name>
    <servlet-class>
        org.apache.axis.transport.http.AxisServlet
    </servlet-class>

A common mistake that people make is placing the init parameters under the AxisServlet 
declaration under <init-param> tags. 

Thanks

You could implement ServiceLifecycle and store the value as an init param in 
your web.xml file.

import javax.xml.namespace.QName;
import javax.xml.rpc.server.ServletEndpointContext;
import javax.xml.rpc.server.ServiceLifecycle;
import javax.xml.rpc.ServiceException;
import javax.servlet.ServletContext;

public class myService implements ServiceLifecycle{
    private String location;

    /**
     * Required by interface, ServiceLifecycle.
     */
    public void init(Object context) throws ServiceException {
        ServletEndpointContext ctx    = (ServletEndpointContext)context;
        ServletContext servletContext = ctx.getServletContext();
        this.location = (String)servletContext.getInitParameter("location");
    }

    /**
     * Required by interface ServiceLifecycle.
     */
    public void destroy(){}
}


This is working for me with Tomat/Apache on both Windows and Linux.
