Remove a repository item by calling the RestRepositoryHelper.removeItem() method. A removeItem() call returns a data stream that contains the string true if the item was removed. If the item was not removed, the call throws an exception.
The following sample removes a repository item:
RestResult result = RestRepositoryHelper.removeItem("/atg/commerce/catalog/ProductCatalog", "product",
"myProductId-12345", params, session);
