Create an ASP page that invokes FirstAppSolution/PreLoanProcess

Within the ASP.NET project, add a web form (an ASPX file) that is responsible for displaying an HTML page to the loan applicant. The web form is based on a class that is derived from System.Web.UI.Page. The C# application logic that invokes FirstAppSolution/PreLoanProcess is located in the Button1_Click method (this button represents the Submit Application button).

The following illustration shows the ASP.NET application

The following table lists the controls that are part of this ASP.NET application.

The application logic that is part of the ASP.NET application must dynamically create an XML data source to pass to the FirstAppSolution/PreLoanProcess process. The values that the applicant entered into the HTML page must be specified within the XML data source. These data values are merged into the form when the form is viewed in Workspace. The classes located in the System.Xml namespace are used to create the XML data source.

When invoking a process that requires XML data from an ASP.NET application, an XML data type is available for you to use. That is, you cannot pass a System.Xml.XmlDocument instance to the process. The fully qualified name of this XML instance to pass to the process is InvokePreLoanProcess.PreLoanProcess.XML. Convert the System.Xml.XmlDocument instance to InvokePreLoanProcess.PreLoanProcess.XML. You can perform this task by using the following code.

//Create the XML to pass to the FirstAppSolution/PreLoanProcess process 
XmlDocument myXML = CreateXML(userName, phone, amount); 
     
//Convert the XML to a InvokePreLoanProcess.PreLoanProcess.XML instance 
StringWriter sw = new StringWriter(); 
XmlTextWriter xw = new XmlTextWriter(sw); 
myXML.WriteTo(xw); 
 
InvokePreLoanProcess.PreLoanProcess.XML inXML = new XML(); 
inXML.document = sw.ToString(); 

To create an ASP page that invokes the FirstAppSolution/PreLoanProcess process, perform the following tasks in the Button1_Click method:

1. Create a FirstAppSolution_PreLoanProcessClient object by using its default constructor.

2. Create a FirstAppSolution_PreLoanProcessClient.Endpoint.Address object by using the System.ServiceModel.EndpointAddress constructor. Pass a string value that specifies the WSDL to the LiveCycle service and the encoding type:

   http://hiro-xp:8080/soap/services/FirstAppSolution/PreLoanProcess?blob=mtom 

   You do not need to use the lc_version attribute. This attribute is used when you create a service reference. However, ensure that you specify?blob=mtom.

   Note: Replace hiro-xp with the IP address of the J2EE application server hosting LiveCycle.

3. Create a System.ServiceModel.BasicHttpBinding object by getting the value of the FirstAppSolution_PreLoanProcessClient.Endpoint.Binding data member. Cast the return value to BasicHttpBinding.

4. Set the System.ServiceModel.BasicHttpBinding object’s MessageEncoding data member to WSMessageEncoding.Mtom. This value ensures that MTOM is used.

5. Enable basic HTTP authentication by performing the following tasks:

   • Assign the LiveCycle user name to the data member FirstAppSolution_PreLoanProcessClient.ClientCredentials.UserName.UserName.

   • Assign the corresponding password value to the data member FirstAppSolution_PreLoanProcessClient.ClientCredentials.UserName.Password.

   • Assign the constant value HttpClientCredentialType.Basic to the data member BasicHttpBindingSecurity.Transport.ClientCredentialType.

   • Assign the constant value BasicHttpSecurityMode.TransportCredentialOnly to the data member BasicHttpBindingSecurity.Security.Mode.

   The following code example shows these tasks.

   //Enable BASIC HTTP authentication 
   BasicHttpBinding b = (BasicHttpBinding)mortgageClient.Endpoint.Binding; 
   b.MessageEncoding = WSMessageEncoding.Mtom; 
   mortgageClient.ClientCredentials.UserName.UserName = "administrator"; 
   mortgageClient.ClientCredentials.UserName.Password = "password"; 
   b.Security.Transport.ClientCredentialType = HttpClientCredentialType.Basic; 
   b.Security.Mode = BasicHttpSecurityMode.TransportCredentialOnly; 
   b.MaxReceivedMessageSize = 2000000; 
   b.MaxBufferSize = 2000000; 
   b.ReaderQuotas.MaxArrayLength = 2000000;

6. Retrieve the name, phone, and amount values that the user entered into the web page. Use these values to dynamically create an XML data source that is sent to the FirstAppSolution/PreLoanProcess process. Create a System.Xml.XmlDocument that represents the XML data source to pass to the process (this application logic is shown in the following code example).

7. Convert the System.Xml.XmlDocument instance to InvokePreLoanProcess.PreLoanProcess.XML (this application logic is shown in the following code example).

8. Invoke the FirstAppSolution/PreLoanProcess process by invoking the FirstAppSolution_PreLoanProcessClient object’s invoke_Async method. This method returns a string value that represents the invocation identifier value of the long-lived process.

9. Create a JobManagerClient by using is constructor. (Ensure that you have set a service reference to the Job Manager service.)

10. Repeat steps 1-5. Specify the following URL for step 2: http://hiro-xp:8080/soap/services/JobManager?blob=mtom.

11. Create a JobId object by using its constructor.

12. Set the JobId object's id data member with the return value of the FirstAppSolution_PreLoanProcessClient object’s invoke_Async method.

13. Assign the value true to the JobId object's persistent data member.

14. Create a JobStatus object by invoking the JobManagerService object 's getStatus method and passing the JobId object.

15. Get the status value by retrieving the value of the JobStatus object's statusCode data member.

16. Assign the invocation identifier value to the LabelJobID.Text field.

17. Assign the status value to the LabelStatus.Text field.
