Data Mashup Service Engine REST Support

This topic provides information about REST support.

• Resources
  
  • Identified Resources
    
• Tables, views, federated views, data mashups of relational or RSS feeds
  
• Reaching to particular page, row, and column
  
  • Supported Parameters
    
• Page – Supports pagination of large result sets
  
• Row – Reaches a particular row irrespective of the page
  
• Column – Reaches a particular column
  
• Extra parameters depend upon the application configuration
  
• Constructing Resource URIs in encoding mode
  Data Mashup Service Engine support of REST.
  
  • To get all the records, the URL is page=0&row=0&column=0.
    
  • To reach a particular page, such as the 2nd page, the URL is: page=2&row=0&column=0.
    If you attempt to reach an invalid page, such as ‐1, the URL returns all the pages.
    
  • To reach a particular row, such as the 10th row, the URL is page=2&row=10&column=0.
    The page value is ignored and only 10th row is displayed. If you attempt to reach a row with an invalid row, all the pages and all the rows are returned.
    
  • To get all the records of a particular attribute, such as CUSTOMER_ID, the URL is page=0&row=0&column=CUSTOMER_ID.
    This lists all the records of attribute CUSTOMER_ID.
    
  • To get only values of the CUSTOMER_ID in 2nd page, the URL is page=2&row=0&column=CUSTOMER_ID.
    
  • To drill down to the 2nd row of the CUSTOMER_ID value , the URL is page=2&row=2&column=CUSTOMER_ID.
    In this instance, the page attribute value is ignored.
    Note - Currently the Data Mashup Service Engine does not support a POST request.
    
• Runtime input arguments
  
  • Runtime-input arguments can be added in the EDM collaboration at design-time.
    
  • Runtime arguments for flat files and tab delimited files are added automatically.
    
• Using runtime arguments with REST queries.
  
  • To reach page=0&row=0&column=0&FILE_LOC_STUDENTINFO=0:
    FILE_LOC_STUDENTINFO is the runtime argument. Once the runtime argument is defined in the collaboration, it is mandatory to mention this argument while accessing URL.
    FILE_LOC_STUDENTINFO=0 is the runtime argument that you are accessing with default values. You can overwrite this value by specifying a file name, such as page=0&row=0&column=0&FILE_LOC_STUDENTINFO=test.xls.
    Note - test.xls is the file name that you overwrite; this must be configured in GlassFish as part of application configuration.
