The assignment of a Processing Rule allows the Java client code to instantiate a
minimal identity transformer and invoke statically configured rule-based
transformations with little overhead.
For example, consider the following two examples. This command sequence
creates the global
coprocXform
Processing Rule.
rule coprocXform
xform INPUT http://10.10.1.66/Diff_part_1.xsl x1
xform x1 http://10.10.1.66/Diff_part_2.xsl x2
xform x2 http://10.10.1.66/Diff_part_3.xsl OUTPUT
exit
Now create the
coproc-1
XSL Coprocessor and assign the
coprocXform
Processing
Rule to it.
xslcoproc coproc-1
local-address 0 6003
xml-manager mgr1
stylesheet-rule coprocXform
exit
The following minimal Java client code invokes the rule and performs the
multistep transformation.
// create new "identity" transformer
transformer = factory.newTransformer();
// transform input file and send result to
stdout
transformer.transform(
new StreamSource(args[0]),
new StreamResult(System.out));
This command sequence creates the global
SignSoapSec
Processing Rule.
rule signSoapSec
xform INPUT store:///sign-soapsec.xsl OUTPUT
exit
Now create the coprocCrypto XSL Coprocessor and assign the SignSoapSec
Processing Rule to the Coprocessor.
xslcoproc coprocCrypto
local-address 0 6003
xml-manager mgr1
stylesheet-rule signSoapSec
crypto-extensions on
exit
The
coprocCrypto
XSL Coprocessor signs the INPUT provided by the client and
returns the signed OUTPUT to the client.
The following minimal Java client code enables the DataPower appliance to
function as a SOAP signature engine.
// create new "identity" transformer
transformer = factory.newTransformer();
// set stylesheet parameter
transformer.setParameter ("keypair", "ALICE");
// transform input file and send result to
