To change the URL you need to do three things:

Change the context root of your web project from magicmonitor to dev
Add the mapping dev/magicmonitor/panels.jsp for your JSP.
Clean Tomcat to remove the existing application settings and pick up the application configuration changes you have made.

Step 1 of 3: Change the context root:

Select your project node in Project Explorer, right click and select Properties.
Select Web Project Settings from the list of entries on the left.
In the Context root field change the value from magicmonitor to dev, then click Apply And Close.

Step 2 of 3: Add a mapping for the JSP:

Edit the project's WebContent/WEB-INF/web.xml to add a mapping for your JSP between the submitted URL and the JSP file:

<servlet>
    <servlet-name>PanelsJsp</servlet-name>
    <jsp-file>/panels.jsp</jsp-file>
</servlet>
<servlet-mapping>
    <servlet-name>PanelsJsp</servlet-name>
    <url-pattern>/magicmonitor/panels.jsp</url-pattern>
</servlet-mapping>

That <url-pattern> will be appended to the context root (which is now dev) when matching the URL you submit. If the URL submitted from the browser matches the <url-pattern> the <jsp-file> will be called.

Step 3: To republish:

In the Servers view: stop Tomcat, select the Tomcat server, right-click and select Clean... from the popup menu.
You will be prompted "Clean will discard ... Are you sure you want to clean all published resources?".
Click OK, then start Tomcat.

You should now be able to access your JSP page using the URL http://localhost:8080/dev/magicmonitor/panels.jsp
