Accessing properties file content

[Rene Richard <re...@nrc.gc.ca>]

Hello,


I would like to read a properties file and get configuration information to
feed into my web service (all of this inside a tomcat container).

I have a hello world web service and I would like to read a properties file
and respond with something inside it. How do I get the servlet context from
inside a CXF web service?

I can also configure this as a Spring bean with properties set in the
configuration file. I don't know how to get the spring context either..

Can someone provide a hint?

R.

In your service, you can have a 
@Resource
WebServiceContext ctx;
thing and for each invoke, you can get the Servlet context out of it.

If it's in spring config, just let spring inject it into your bean.

I guess you mean this?

Filename:service_ws.xml

		<property name="jdbcUser" value="${one.two.jdbc.user}"/>
		<property name="jdbcPwd" value="${one.two.jdbc.password}"/>
	</bean>

and so on...

You see, the properties file 'myprops.properties' is accesible over the predefined JBOSS property '${jboss.server.config.url}'.
But the use of the JBOSS property is of course optional. Any valid path suffices.
After the property file is read, the property values are directly usable for initialising your beans,
i.e. : <property name="jdbcDriver" value="${one.two.jdbc.driver}"/>

The above file is referred to in web.xml:
<?xml version="1.0" encoding="UTF-8"?>
<web-app
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns="http://java.sun.com/xml/ns/javaee"
	xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
						http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
	id="WebService"
	version="2.5">

	<display-name>WebService</display-name>
    <description>WebService</description>

	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>WEB-INF/service_ws.xml</param-value>
	</context-param>

	<context-param>
		<param-name>webAppRootKey</param-name>
		<param-value>WebService</param-value>
	</context-param>

	<listener>
		<listener-class>
			org.springframework.web.util.Log4jConfigListener
		</listener-class>
	</listener>

	<listener>
		<listener-class>
			org.springframework.web.context.ContextLoaderListener
		</listener-class>
	</listener>

	<servlet>
		<servlet-name>CXFServlet</servlet-name>
		<servlet-class>
			org.apache.cxf.transport.servlet.CXFServlet
		</servlet-class>
	</servlet>
	<servlet-mapping>
		<servlet-name>CXFServlet</servlet-name>
		<url-pattern>/services/*</url-pattern>
	</servlet-mapping>

</web-app>

So during startup the whole mess is activated...
