Options

WSDL location

URL to the webservice's WSDL file. After entering the URL you have to click on the Analyze button. Note that fetching and parsing the WSDL takes place in background (buttons will be disabled).

User

The user name as required by the service endpoint.

Password

The password as required by the service endpoint.

Timout

Timeout as passed to the service endpoint.

Retain job after completion

Whether to keep the result files on the server after the job completes.

Continue job after timeout

Whether to keep job running after timeout occurs.

Input

Table with all required input parameters which you have to be mapped to columns or constant values as described above. The table represents elements of a tree that is constructed by analyzing the complex input parameter types. The different columns represent:

• Parameter: The name of the parameter
• Type: Type of the parameter (this can be as easy as string or double but also more complex, such as the name of dynamically generated classes)
• Constant?: A check box for all leave elements. Select this box to assign a constant value that you enter in the text field next to this entry. If unselected, use the value of the column that is selected in the right-most column.
• Constant value: The value that is to be used when the "Constant?" check box is selected. The entered string must comply with the expected type (otherwise the execution will fail).
• Mapped column: The column whose value is used for the current invocation.

Output

Table with all output values which you can assign to new column in the output table as described above. The values in the column are as follows:

• Parameter: The name of the parameter (see above)
• Type: Type of the parameter (see above)
• Include?: Whether to include this parameter in the output table. It selected, this value will constitute one new column in the output table.
• Output column?: The name of the column that will be append to the output table.
• All in list: If a type represents a collection and this option is checked, all list elements will be returned. Each list element will thereby be represented by a separate row. If unselected, only the first list element (if any) will be returned. Note that if you have lists of lists in the output parameter tree (both of which are checked), these will be flattened (the row count for a single invocation is outer_list_size times inner_list_size). Likewise, if the output parameter tree contains different lists on the same level, these will be treated independently, whereby new output columns that are covered by the elements in one list will be filled with missing values when processing the respectively other list.

Override Endpoint

If selected, the webservice endpoint as given in the wsdl will be overwritten using the value entered in the accompanying text field.

Add SOAP Header

An XML tree that will be inserted into the soap header of outgoing soap request (for instance identification tags required by the server). Note, the text snippet needs to be valid XML.

Parallel Invocation Count

The number of maximum asynchronous invocations (an invocation translates to the processing of a single input row). The "optimal" number depends on the endpoint. A high number increases the parallel job count at the service endpoint, possibly leading to an overload situation or a lock-out of the client. A low value increases the overall execution time.

Row Cache Size

The number of rows to be kept in memory at most. The output table will retain the same ordering as the input table. If for any reason the processing of a row takes significantly longer than the processing time of other rows, the webservice invocation will stall, keeping at most this number of rows in memory.

New RowID suffix

The string (usually only a character such as '_') is used when the webservice returns a list, and new row IDs need to be created. These new IDs will have the same base name as the original row ID + a suffix (the value entered here) + an increasing counter.
