Description of problem:
Tomcat 7 datasources are not discovered if defined in server.xml file. At the same time, datasources will be properly discovered when defined in the context.xml file.

It seems that the problem is in the name of the MBean that tomcat plugin expects to see:

- if datasource is defined using server.xml file, the MBean name will be: Catalina:type=DataSource,class=javax.sql.DataSource,name="jdbc/mysql";

- if datasource is defined using context.xml file, the MBean name is: Catalina:type=DataSource,context=/examples,host=localhost,class=javax.sql.DataSource,name="jdbc/mysql"

Version-Release number of selected component (if applicable):
- JBoss ON 3.2
- Red Hat JBoss Web Server 2.1.0 
- Web Server Plugin Pack for Red Hat JBoss Operations Network 3.2.0 (the same result is when plugin is updated with: Web Server Plugin Pack Update-01 for JBoss ON 3.2)

How reproducible:
Always

Steps to Reproduce:
1. Install and start JBoss ON 3.2
2. Download, install  and configure EWS 2.1.0 and Tomcat 7; 
3. Install JBoss ON plugin for EWS;
3. Define datasource in the context.xml file - for instance add the following Resource inside Context:

***********************
...
<Context>
...
    <Resource auth="Container"
              name="jdbc/mysql"
              type="javax.sql.DataSource"
              driverClassName="com.mysql.jdbc.Driver"
              url="jdbc:mysql://localhost:3306/test"
              username="userName" password="password" />
</Context>
***********************
4. Save the file, restart the Tomcat;
5. Navigate to the JBoss ON UI -> Tomcat Servers -> Tomcat instance -> Tomcat Virtual Hosts -> localhost -> Tomcat Web Application (WAR)s -> example and there should be Tomcat Datasoruces with the "jdbc/mysql" discovered;
6. Shutdown Tomcat instance and uninventory it from the JBoss ON UI;
7. Delete Resource configuration (given in the step 3 above) from context.xml and instead add the following in the context.xml file:
***********************
<Context>
...
<ResourceLink name="jdbc/mysql" 
              global="jdbc/mysql"
              auth="Container"
              type="javax.sql.DataSource" />
</Context>
***********************
   
Above Resource configuration add to the Tomcat's server.xml file:

***********************
<GlobalNamingResources>
...
    <Resource auth="Container"
              name="jdbc/mysql"
              type="javax.sql.DataSource"
              driverClassName="com.mysql.jdbc.Driver"
              url="jdbc:mysql://localhost:3306/test"
              username="userName" password="password" />
</GlobalNamingResources>
***********************
and save the file.
8. Start Tomcat server again and let JBoss ON Agent discover it;

Actual results:
No datasource is discovered

Expected results:
Globally defined datasources should be discovered.
