BatchUploader

public class BatchUploader
extends Canvas

The BatchUploader handles the upload, validation, review and saving of a dataset expressed in CSV or other upload formats.

NOTE: BatchUploader is only available with Smart GWT Power or better.

By default, a BatchUploader consists of a single FileItem form field. This form field will upload a file using the special "batchUpload" built-in DataSource. The uploaded file data will be parsed and validated using the uploadDataSource, then streamed back to the browser, along with any errors, for display in a ListGrid.

The user can then correct any errors and submit the final dataset, which will be added to the DataSource via a series of "add" DSRequests, all submitted as a single HTTP request via request queuing.

Additional form fields can be added to the form that uploads the data file via uploadFormFields. Values entered into these fields are not included in the "add" DSRequests used to store the uploaded records. Instead, they are stored as HttpSession attributes with the names corresponding to the names of the specified uploadFormFields (optionally with a prefix applied, in case this is necessary to avoid name collisions in the session). This allows any custom logic for the "add" operation to access these additional fields via httpSession.getAttribute().

Because all records are saved in a single HTTP request, a similar strategy of storing data as servletRequest or session attributes allows reuse of objects required to perform the "add" operations (such as field values common to all added records, or a SQL connection or transaction manager).

If uploadFieldName is set on any of the uploadDataSource's fields, the BatchUploader will use that name to map the uploaded file's content.

A couple of server-side techniques are interesting in conjunction with the BatchUploader. One is to set the DataSource.serverConstructor property to point at your own class that inherits from com.isomorphic.datasource.BasicDataSource. The most interesting reason for doing this is to override the validate method and provide complete custom validation - for example, checking relations to other tables.

Another technique is to handle the initial Smart GWT call in your own servlet, by setting the dataURL property. You then handle the add requests with a combination of your own code and Smart GWT server API calls. This is a good way to add special pre- and post-processing to the normal server-side flow.

The BatchUploader sample, provided as one of the databinding examples, demonstrates both of these techniques. We use a special subclass of DataSource and override the validate method as described above; we also set dataURL to point at a JSP that wraps the queue of Smart GWT requests inside a single database transaction (a servlet would be more usual, but we use a JSP for ease of modification)

Note: The special "batchUpload" DataSource, which should reside in the shared/ds folder of your application's webroot (see Installation Instructions). is not part of your application's data flow, and it has nothing to do with the uploadDataSource you use to actually persist the validated and error-corrected data: it is simply a means to uploading the raw data in the first place. Normally, you should simply ignore its presence and treat it as an internal detail of the Smart GWT framework.

However, there are circumstances in which you may wish to change it to achieve specific aims. For example, you may wish to override the Java class it invokes, in order to insert your own security or other validation logic into the initial upload flow. This is entirely in keeping with the design, but we regard it as an out-of-the-ordinary use-case: normal usage is simply to ignore the presence of the batchUpload DataSource.

setDefaultProperties

public static void setDefaultProperties(BatchUploader batchUploaderProperties)

Class level method to set the default properties of this class. If set, then all existing and subsequently created instances of this class will automatically have default properties corresponding to the properties set on the SmartGWT class instance passed to this function before its underlying SmartClient JS object was created. This is a powerful feature that eliminates the need for users to create a separate hierarchy of subclasses that only alter the default properties of this class. Can also be used for skinning / styling purposes.

Note: This method is intended for setting default attributes only and will affect all instances of the underlying class (including those automatically generated in JavaScript). This method should not be used to apply standard EventHandlers or override methods for a class - use a custom subclass instead. Calling this method after instances have been created can result in undefined behavior, since it bypasses any setters and a class instance may have already examined a particular property and not be expecting any changes through this route.

Parameters:

batchUploaderProperties - properties that should be used as new defaults when instances of this class are created

setUploadFormItems

public void setUploadFormItems(FormItem... items)
                        throws java.lang.IllegalStateException
