## Running Student-Teacher MDR in Eclipse

Eclipse is required to run this MDR.

The example MDR can be tested by running within Eclipse. Use these steps to run the Example MDR:

1. Right click on the web project, and select Run As... > Run on Server
2. Select the web server, and click Next
3. Click Finish on the next screen. The COSMOS Web UI is automatically displayed in Eclipse.
4. Find your MDR in the data managers list, and use the context menu to submit queries to it.

You may want to run the web service in debug mode so that you can step through the code. To run in debug mode, select "Debug as..." instead of "Run As..." in step 1 above.
