This is a Java API is for communicating with HP Autonomy ACI servers.
The Autonomy Content Infrastructure (ACI) is a protocol for communicating with HP Autonomy servers using XML over HTTP. This Java API provides an interface for constructing and executing ACI requests and for consuming ACI responses. Previous versions were available as jar files from HP Autonomy customer support.
java-aci-api-ng is available from the central Maven repository.

The AciService’s executeAction methods are responsible for executing ACI actions. An AciServiceImpl can either be created with the host and port for an ACI server, or the executeAction method must be called with a host and port each time.
AciService aciService = new AciServiceImpl(
new AciHttpClientImpl(new DefaultHttpClient()),
new AciServerDetails(host, port)
);
The AciParameters class can be used to construct a request:
AciParameters parameters = new AciParameters("QUERY");
parameters.add("text", "*");
parameters.add("totalResults", true);
To execute this request, the AciService executeAction method should be called with the AciParameters and a Processor to consume the response. In the following example, the included DocumentProcessor is used to convert the XML response into a DOM document which can then be inspected either directly or using XPath.
Document response = aciService.executeAction(parameters, new DocumentProcessor());
XPath xpath = XPathFactory.newInstance().newXPath();
Number totalResults = (Number) xpath.evaluate("/autnresponse/responsedata/autn:numhits", response, XPathConstants.NUMBER);
Preferably, the ACI Annotations Processor Factory can be used to easily convert the response to an instance of a Java class defined by you.
Previous versions of this library included a taglib for use in JSPs and support for legacy OEM encryption. Builds with these features are available from HP Autonomy customer support.
