The
Web Service Settings dialog box lets you create the SOAP message
to send to the web service to invoke a web service operation.
After you provide the URL to the web service definition, Web
Service Settings interprets the definition and populates other values
on the tab. You can then select the web service operation to invoke.
Based on the operation that you select, a template of the SOAP request
message is generated. You then insert values into the message as
required.
Web Service Settings also let you test your invocation request
by sending a test message and displaying the response message that
the web service sends.
Settings tabUse the settings tab to provide a link to the web service
definition and to provide the information required to connect to
a web service. You can also access web services from a LiveCycle
Server. (See Invoking services in LiveCycle using Web Services.)
WSDL URLThe URL of the web service definition. The definition is
written in web service definition language (WSDL). WSDLs contain
all the information that web service clients require to call web
service operations and process the response.
Note: The LiveCycle Server must be able to access the WSDL URL at
run time and at design time.
If you have access to the service, click Load after you enter
the value for WSDL URL. Clicking Load causes Web Service Settings
to read and interpret the definition. It then automatically populates
many of the properties on the Settings tab, such as the Target URL
property.
 If your development environment has network limitations
that prevent you from accessing the web service, save the WSDL file
to the file system, and load that file to populate the other property
values. After loading the file, you replace the value of the WSDL
URL property with the actual URL for the service definition. User NameThe user name of the account that you can use to access
the web service. Provide a user name only if the web service requires
authentication.
If the user name is saved as process data, you can type the XPath
expression that resolves to the location where the user name is
stored. Click XPath to open XPath Builder.
PasswordThe password that corresponds with the user name that you
provided for the User Name property.
If the password is saved as process data, you can type the XPath
expression that resolves to the location where the password is stored.
If the expression resolves to a variable, set a default value for
the variable to use for testing. Click XPath to open XPath Builder.
PortThe service that you want to use, that is exposed through
the WSDL URL. A WSDL URL can have multiple services available. After
the WSDL URL is loaded, this list is populated with the available
ports. (See WSDL URL.)
Target URLThe URL that provides access to the web service. After
the value for Port is specified, the default target URL as defined
in the WSDL is displayed. You can override this target URL value
by typing the actual target URL for the selected port.
If the URL is saved as process data, you can type the XPath expression
that resolves to the location where the value is stored. If the
expression resolves to a variable, set a default value for the variable
to use for testing. Click XPath to open XPath Builder.
When you access web services from a LiveCycle Server, append ?wsdl&async=true&lc&lc_version=9.0.0
to the URL when the service is an asynchronous service. Services
for long-lived processes are asynchronous.
OperationThe web service operation to invoke. The list is populated
automatically if you loaded the web service definition. (See WSDL URL.)
Time Out (in secs)The amount of time that you want to wait for a response
from the web service before abandoning the web service invocation.
The value you provide is in seconds.
If the time-out value is saved as process data, you can type
the XPath expression that resolves to the location where the value
is stored. If the expression resolves to a variable, set a default
value for the variable to use for testing. Click XPath to open XPath
Builder.
WSDL ContentThe WSDL that is retrieved from the URL provided for the
WSDL URL property. The WSDL appears when you click the Load button.
Embed WSDLSelect this option to embed the WSDL in the process. When
selected, the embedded WSDL is used when the invoke operation executes
at run time. The embedded WSDL is updated each time you click the
Load button.
If this option is not selected, the WSDL is retrieved from the
WSDL URL at run time.
HTTP Settings tabUse the HTTP Settings tab to configure settings related
to the HTTP protocol.
- Send Authentication Headers Without First Receiving
An Authentication Challenge:
- Select when the web service does not send a challenge request
for authentication.
Request tabUse the Request tab to create the SOAP request message
that is sent to the web service to invoke the operation.
SOAP RequestThe SOAP message to send to the web service at
run time. For more information about SOAP messages, see About SOAP invocation messages.
If you loaded the WSDL and
selected the port and operation to invoke, click Generate to populate
the editing box with a template message. (See WSDL URL.) The template message is complete except for the values
that you must provide for the required operation parameters. Question
marks (?) indicate values that you must provide.
Click
Remove ’?’ to remove all the question marks from the SOAP request. If
the operation has optional parameters that you want to provide values
for, select Include Optional. This option includes the XML for optional
parameters in the message.
If you cannot load the service
definition, enter the message manually.
To use values in process
data for operation parameters, use XPath expressions that evaluate
to the data location. XPath expressions must appear inside braces and
between dollar signs, as in {$expression$}. Click
XPath to open XPath Builder. The expression that you create with
XPath builder is inserted at the location of the cursor in the editing
box.
The following example template message shows a request
to invoke a web service’s invoke operation. The
values for the parameters intvar and strvar have
a question mark as placeholder values.
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:ser="http://adobe.com/idp/services">
<soapenv:Header/>
<soapenv:Body>
<ser:invoke>
<ser:intvar>?</ser:intvar>
<ser:strvar>?</ser:strvar>
</ser:invoke>
</soapenv:Body>
</soapenv:Envelope>
SOAP Request For TestThe SOAP request to send to the web service
for testing at design time.
As with the SOAP Request property,
if you have loaded the web service definition, click Generate to
populate the editing box with a template message. (See WSDL URL.) The template message is complete except for the values
that you must provide for operation parameters. Question marks (?)
indicate values that you must provide.
Click
Remove ’?’ to remove all the question marks from the SOAP request. If
the message includes XPath expressions as parameter values, the
expressions must resolve to process variables that are configured
with a default value. Otherwise, replace the parameters with literal
values for testing.
You use the Test tab to test the message.
(See Test tab.)
Attachment tabUse the Attachments tab to add file attachments to the
SOAP message. You can add attachments only if the web service definition
indicates that they are allowed or required. Also, the file to attach
must already be saved as process data so that you can reference
it.
Note: To add required attachments, you must have already
loaded the WSDL, selected the port and operation, and defined the
SOAP request message. (See WSDL URL.)
Each row in the table represents a file attachment:
Click Load Attachment Part to add rows to the table for
the attachments that must be specified for the web service operation
that you are invoking. The Part and Type columns are populated with
values automatically.
Click Add Attachment Part to add rows to the table for optional
attachments that the WSDL does require. The default value for Part
is <anonymous>. You can change the value as required. When
you click the button, XPath Builder opens so that you can create
an expression that evaluates to the document to attach.
Select a row and click Remove Attachment Part to remove the
attachment.
For each attachment, you must provide values for Attachment and
Content-type:
- Attachment:
- Click the cell, and then click the ellipsis button
 that
appears to open XPath Builder. The XPath expression that you create
must resolve to the location where the attachment is saved. - Content-Type:
- Type the MIME type of the file that you are attaching, for example application/pdf.
Test tabUse this tab to test the SOAP message that you created
for testing on the Request tab. To test the message, the message
is sent to invoke the web service operation that you previously
specified.
Click Test to send the test message to invoke the web service
operation. The response message that the web service returns appears
in the text area.
Note: To test, you cannot use XPath Expression as
property values because the process data that they resolve to does
not yet exist at design time.
