You can create search rules that result in the Output service examining
input data and using different form designs based on the data content
to generate output. For example, if the text mortgage is
located within the input data, then the Output service can use a
form design named Mortgage.xdp. Likewise, if the text automobile is
located in the input data, then the Output service can use a form
design that is saved as AutomobileLoan.xdp. Although the Output
service can generate different output types, this section assumes
that the Output service generates a PDF file. The following diagram
shows the Output service generating a PDF file by processing an
XML data file and using one of many form designs.
In addition, the Output service is able to generate document
packages, where multiple records are provided in the data set and
each record is matched to a form design and a single document is
generated made up of multiple form designs.
Summary of stepsTo instruct the Output service to use
search rules while generating a document, perform the following
steps:
Include project files.
Create an Output Client object.
Reference an XML data source.
Define search rules.
Set PDF run-time options.
Set rendering run-time options.
Generate a PDF document.
Retrieve the results of the operation.
Include project filesInclude necessary files in your development
project. If you are creating a client application using Java, then
include the necessary JAR files. If you are using web services,
then make sure that you include the proxy files.
The following
JAR files must be added to your project’s classpath:
adobe-livecycle-client.jar
adobe-usermanager-client.jar
adobe-output-client.jar
adobe-utilities.jar (Required if LiveCycle is deployed
on JBoss)
jbossall-client.jar (Required if LiveCycle is deployed
on JBoss)
if LiveCycle is deployed on a
supported J2EE application server that is not JBoss, then you will
need to replace adobe-utilities.jar and jbossall-client.jar with
JAR files that are specific to the J2EE application server on which LiveCycle is deployed.
Create an Output Client objectBefore you can programmatically
perform an Output service operation, you must create an Output service
client object.
Reference an XML data sourceAn XML element must exist for every
form field that you want to populate with data. The XML element
name must match the field name. An XML element is ignored if it
does not correspond to a form field or if the XML element name does
not match the field name. It is not necessary to match the order
in which the XML elements are displayed, as long as all XML elements
are specified.
Define search rulesTo define search rules, you define one or
more text patterns that the Output services searches for in the
input data. For each text pattern that you define, you specify a
corresponding form design that is used if the text pattern is located.
If a text pattern is located, then the Output service uses the corresponding
form design to generate the output. An example of a text pattern
is mortgage.
注意： If text patterns are
not located, then the default form is used. Make sure that all form
designs that you use are located in the content root.
Set PDF run-time optionsSet the following PDF run-time options
in order for the Output service to successfully create a PDF document
based on multiple form designs:
File URI: Specifies
the name and location of the PDF file that the Output service generates.
Rules: Specifies rules that you defined.
LookAHead: Specifies the number of bytes to use from
the beginning of the input data file to scan for the defined text
patterns. The default is 500 bytes.
Set rendering run-time optionsYou can set rendering run-time
options while creating PDF files. Although these options are not
required (unlike PDF run-time options), you can perform tasks such
as improving the performance of the Output service. For example,
you can cache the form design that the Output service uses in order
to improve performance.
Generate a PDF documentAfter you reference a valid XML data source
and set run-time options, you can invoke the Output service resulting
in it generating a PDF document. If the Output service locates a
specified text pattern in the input data, then it uses the corresponding
form design. If a text pattern is not used, then the Output service uses
the default form design.
Retrieve the results of the operationAfter the Output service
performs an operation, it returns XML data that specifies whether
the operation was successful.
Create search rules using the Java APICreate search rules by using the Output API (Java):
Include project files.

You do not need to use the lc_version attribute.
This attribute is used when you create a service reference. However,
specify ?blob=mtom to use MTOM.
Create a System.ServiceModel.BasicHttpBinding object
by getting the value of the OutputServiceClient.Endpoint.Binding field.
Cast the return value to BasicHttpBinding.
Set the System.ServiceModel.BasicHttpBinding object’s MessageEncoding field

for each Rule object.
Set PDF run-time options
Create a PDFOutputOptionsSpec object
by using its constructor.
Set the file URI option by assigning a string value that
specifies the location of the PDF file that the Output service generates
to the PDFOutputOptionsSpec object’s fileURI data
member. The File URI option is relative to the J2EE application
server hosting LiveCycle, not the client computer.

member.
注意： You cannot set the version
of the PDF document by using the RenderOptionsSpec object’s pdfVersion member
if the input document is an Acrobat form. The output PDF document
retains the PDF version of the Acrobat form. Likewise, you cannot
set the tagged PDF option by using the RenderOptionsSpec object’s taggedPDF method
if the input document is an Acrobat form.
注意： You
cannot set the linearized PDF option by using the RenderOptionsSpec object’s linearizedPDF member
if the input PDF document is certified or digitally signed. For
information, see Digitally Signing PDF Documents.
