I'm using JRules Studio to develop some extremely simple rules. The rules populate an IN_OUT parameter. When the test finishes, is there a way of interrogating the values in the IN_OUT object?
Initially I'd like to interrogate it in the debugger, but any other ideas would be welcomed.
I am not sure to understand the question:
Your JAVA code is like this:
IlrSessionFactory factory = new IlrJ2SESessionFactory();
IlrStatelessSession session = factory.createStatelessSession();
IlrSessionRequest sessionRequest = factory.createRequest();
sessionRequest.setRulesetPath(“/RuleAppName/rulesetName”);
sessionRequest.setTraceEnabled(true);
sessionRequest.getTraceFilter().setInfoAllFilters(true);
Map inputParameters = new HashMap ();
Report in_report = new Report(); // no-arg constructor
// ... populate the Object ...
inputParameters.put("report", in_report);
sessionRequest.setInputParameters(inputParameters);
IlrSessionResponse sessionResponse = session.execute(sessionRequest);
Report out_report = (Report)sessionResponse.getOutputParameters().get("report“);
And then you play with your "out" parameters... As you would do with any JAVA object
If you want to see them at debug time, I would say:
1/ (not tested) Have a look on the "working memory tab" in the debugger perspective
I am not sure but this is the easiest way to find them if it is visible here
2/ (tested) in the initial action of the starting point of your ruleflow, add:
context.insert(the technical name of your parameter);
Not the "business name". Anyway avoid using BAL in technical artifact such as ruleflow, IRL rules!
By doing this you force the engine to insert your parameter in the working memory.
No duplication (don't worry, it will work like a charm) but as far as I can remember this is the shortest way to make them visible in the Eclipse debugger in JRules
Hope it helps

Barcode recognition is disabled by default in Abbyy Fine Reader Engine 12.
In order to enable it, I need to set the DetectBarcodes property of the PageAnalysisParams Object to TRUE.
Can anyone please help me, how can I set this property true in my java code sdk?
This is the property which we have to set:
public native void setDetectBarcodes(boolean arg0);
How can we call the native function from the java code?
Because calling directly with the object it is giving error.
Error: The local variable pageAnalysisParams may not have been initializedJava(536870963)
To get/initalize an instance of IPageAnalysisParams you can:
IPageAnalysisParams pageAnalysisParams = engine.CreatePageAnalysisParams();
You can also obtain an instance from "document processing params", like:
IDocumentProcessingParams documentparams = engine.CreateDocumentProcessingParams();
IPageAnalysisParams pageAnalysisParams = documentparams.getPageProcessingParams().getPageAnalysisParams();
source: https://github.com/search?q=IPageAnalysisParams&type=code
Looking at the public code samples, you should:
Obtain an instance of IDocumentProcessingParams (dpParams).
Tune that object (and sub-objects(page analysis params)).
And pass that to: document.Process(dpParams);
As #xerx593 suggested, programatically tuning document processing params is a perfectly valid answer.
Another valid answer is to use a configuration file, for example custom_barcode_profile.ini, and fill it according to your needs. This allows you to have better control and readibility over your profiles:
...
[PageAnalysisParams]
DetectBarcodes = TRUE
...
Use your ABBYY SDK documentation and/or ABBYY java wrapper classes to fine tune other parameters, then instead of using document.Process(dpParams);, instantiate an engine object and pass your custom_barcode_profile.ini file to it:
IEngine engine = Engine.InitializeEngine(<your sdk & license params>);
engine.LoadProfile("custom_barcode_profile.ini");
IFRDocument document = engine.CreateFRDocument();
document.AddImageFile("document.png", null, null);
document.Process(null);
document.Export("result.xml", FileExportFormatEnum.FEF_XML, null);
You cannot programatically "mix" multiple predefined profiles into one, you need to add parameters to a custom profile or even create another one and pass it to your engine object.
To enable table detection in the profile we defined later, look for parameters that affects table detection in the documentation, such as DetectTables, and add it to your custom profile:
...
[PageAnalysisParams]
DetectBarcodes = TRUE
DetectTables = TRUE
...
First, some background why I want this crazy thing. I'm building a Plugin in Jenkins that provides an API for scripts that are started from a pipeline-script to independently communicate with jenkins.
For example a shell-script can then tell jenkins to start a new stage from the running script.
I've got the communication between the script and Jenkins working, but the problem is that I now want to try and start a stage from a callback in my code but I can't seem to figure out how to do it.
Stuff I've tried and failed at:
Start a new StageStep.java
I can't seem to find a way to correctly instantiate and inject the step into the lifecycle. I've looked into DSL.java, but cant seem to get to an instance to call invokeStep(), nor was I able to find out how to instantiate DSL.java with the right environment.
Look at StageStepExecution.java and do what it does.
It seems to either invoke the body with an Environment Variable and nothing else, or set some actions and save the state in a config file when it has no body. I could not find out how the Pipeline: Stage View Plugin hooks into this, but it doesn't seem to read the config file. I've tried setting the Actions (even the inner class through reflection) but that did not seem to do anything.
Inject a custom string as Groovy body and call it with csc.newBodyInvoker()
A hacky solution I came up with was just generating the groovy script and running it like the ParallelStep does. But the sandbox does not allow me to call new GroovyShell().evaluate(""), and If I approve that call, the 'stage' step throws a MissingMethodException. So I also do not instatiate the script with the right environment. Providing the EnvironmentExpander does not make any difference.
Referencing and modifying workflow/{n}.xml
Changing the name of a stage in the relevant workflow/{n}.xml and rebooting the server updates the name of the stage, but modifying my custom stage to look like a regular one does not seem to add the step as a stage.
Stuff I've researched:
If some other plugin does something like this, but I couldn't find any example of plugins starting other steps.
How Jenkins handles the scripts and starts the steps, but It seems as though every step is directly called through the method name after the script is parsed, and I found no way to hook into this.
Other plugins using the StageView through other methods, but I could not find any.
add an AtomNode as a head onto the running thread, but I couldn't find how to replace/add the head and am hesitant to mess with jenkins' threading.
I've spent multiple days on this seemingly trivial call, but I can't seem to figure it out.
So the latest thing I tried actually worked, and is displayed correctly, but it ain't pretty.
I basically reimplemented the implementation of DSL.invokeStep(), which required me to use reflection A LOT. This is not safe, and will break with any changes of course so I'll open an issue in the Jenkins' ticket system in the hopes they will add a public interface for doing this. I'm just hoping this won't give me any weird side-effects.
// First, get some environment stuff
CpsThread cpsThread = CpsThread.current();
CpsFlowExecution currentFlowExecution = (CpsFlowExecution) getContext().get(FlowExecution.class);
// instantiate the stage's descriptor
StageStep.DescriptorImpl stageStepDescriptor = new StageStep.DescriptorImpl();
// now we need to put a new FlowNode as the head of the step-stack. This is of course not possible directly,
// but everything is also outside of the sandbox, so putting the class in the same package doesn't work
// get the 'head' field
Field cpsHeadField = CpsThread.class.getDeclaredField("head");
cpsHeadField.setAccessible(true);
Object headValue = cpsHeadField.get(cpsThread);
// get it's value
Method head_get = headValue.getClass().getDeclaredMethod("get");
head_get.setAccessible(true);
FlowNode currentHead = (FlowNode) head_get.invoke(headValue);
// crate a new StepAtomNode starting at the current value of 'head'.
FlowNode an = new StepAtomNode(currentFlowExecution, stageStepDescriptor, currentHead);
// now set this as the new head.
Method head_setNewHead = headValue.getClass().getDeclaredMethod("setNewHead", FlowNode.class);
head_setNewHead.setAccessible(true);
head_setNewHead.invoke(headValue, an);
// Create a new CpsStepContext, and as the constructor is protected, use reflection again
Constructor<?> declaredConstructor = CpsStepContext.class.getDeclaredConstructors()[0];
declaredConstructor.setAccessible(true);
CpsStepContext context = (CpsStepContext) declaredConstructor.newInstance(stageStepDescriptor,cpsThread,currentFlowExecution.getOwner(),an,null);
stageStepDescriptor.checkContextAvailability(context); // Good to check stuff I guess
// Create a new instance of the step, passing in arguments as a Map
Map<String, Object> stageArguments = new HashMap<>();
stageArguments.put("name", "mynutest");
Step stageStep = stageStepDescriptor.newInstance(stageArguments);
// so start the damd thing
StepExecution execution = stageStep.start(context);
// now that we have a callable instance, we set the step on the Cps Thread. Reflection to the rescue
Method mSetStep = cpsThread.getClass().getDeclaredMethod("setStep", StepExecution.class);
mSetStep.setAccessible(true);
mSetStep.invoke(cpsThread, execution);
// Finally. Start running the step
execution.start();
I am currently trying to implement file exports in background so that the user can do some actions while the file is downloading.
I used the apache isis CommandExexuteIn:Background action attribute. However, I got an error
"Not an (encodable) value", this is an error thrown by the ScalarValueRenderer class.
This is how my method looks like:
#Action(semantics = SemanticsOf.SAFE,
command = CommandReification.ENABLED)
commandExecuteIn = CommandExecuteIn.BACKGROUND)
public Blob exportViewAsPdf() {
final Contact contact = this;
final String filename = this.businessName + " Contact Details";
final Map<String, Object> parameters = new HashMap<>();
parameters.put("contact", contact);
final String template = templateLoader.buildFromTemplate(Contact.class, "ContactViewTemplate", parameters);
return pdfExporter.exportAsPdf(filename, template);
}
I think the error has something to do with the command not actually invoking the action but returns the persisted background command.
This implementation actually worked on the method where there is no return type. Did I miss something? Or is there a way to implement background command and get the expected results?
interesting use case, but it's not one I anticipated when that part of the framework was implemented, so I'm not surprised it doesn't work. Obviously the error message you are getting here is pretty obscure, so I've raised a
JIRA ticket to see if we could at least improve that.
I'm interested to know in what user experience you think the framework should provide here?
In the Estatio application that we work on (that has driven out many of the features added to the framework over the last few years) we have a somewhat similar requirement to obtain PDFs from a reporting server (which takes 5 to 10 seconds) and then download them. This is for all the tenants in a shopping centre, so there could be 5 to 50 of these to generate in a single go. The design we went with was to move the rendering into a background command (similar to the templateLoader.buildFromTemplate(...) and pdfExporter.exportAsPdf(...) method calls in your code fragment, and to capture the output as a Document, via the document module. We then use the pdfbox addon to stitch all the document PDFs together as a single downloadable PDF for printing.
Hopefully that gives you some ideas of a different way to support your use case
Thx

Is there any way to inspect or enumerate the Custom Slot Values that are set-up in your interaction model? For Instance, Say you have an intent schema with the following intent:
{
"intent": "MySuperCoolIntent",
"slots":
[
{
"name": "ShapesNSuch",
"type": "LIST_OF_SHAPES"
}
]
}
Furthermore, you've defined the LIST_OF_SHAPES Custom Slot to have the following Values:
SQUARE
TRIANGLE
CIRCLE
ICOSADECAHECKASPECKAHEDRON
ROUND
HUSKY
Question: is there a method I can call from my Speechlet or my RequestStreamHandler that will give me an enumeration of those Custom Slot Values??
I have looked through the Alexa Skills Kit's SDK Javadocs Located Here
And I'm not finding anything.
I know I can get the Slot's value that is sent in with the intent:
String slotValue = incomingIntentRequest.getIntent().getSlot("LIST_OF_SHAPES").getValue();
I can even enumerate ALL the incoming Slots (and with it their values):
Map<String, Slot> slotMap = IncomingIntentRequest.getIntent().getSlots();
for(Map.Entry<String, Slot> entry : slotMap.entrySet())
{
String key = entry.getKey();
Slot slot = (Slot)entry.getValue();
String slotName = slot.getName();
String slotValue = slot.getValue();
//do something nifty with the current slot info....
}
What I would really like is something like:
String myAppId = "amzn1.echo-sdk-ams.app.<TheRestOfMyID>";
List<String> posibleSlotValues = SomeMagicAlexaAPI.getAllSlotValues(myAppId, "LIST_OF_SHAPES");
With this information I wouldn't have to maintain two separate "Lists" or "Enumerations"; One within the interaction Model and another one within my Request Handler. Seems like this should be a thing right?
No, the API does not allow you to do this.
However, since your interaction model is intimately tied with your development, I would suggest you check in the model with your source code in your source control system. If you are going to do that, you might as well put it with your source. Depending on your language, that also means you can probably read it during run-time.
Using this technique, you can gain access to your interaction model at run-time. Instead of doing it automatically through an API, you do it by best practice.
You can see several examples of this in action for Java in TsaTsaTzu's examples.
No - there is nothing in the API that allows you to do that.
You can see the full extent of the Request Body structure Alexa gives you to work with. It is very simple and available here:
https://developer.amazon.com/public/solutions/alexa/alexa-skills-kit/docs/alexa-skills-kit-interface-reference#Request%20Format
Please note, the Request Body is not to be confused with the request, which is a structure in the request body, with two siblings: version and session.
I need to execute the following steps:
1. Start an IE browser window and open a URL (Done using StartBrowser(final string URL)
2. Start a session (done by logging in)
3. Now, I want to enter a different URL in the same browser window which has the same session.
My question is related to Step 3. How can I overwrite the URL in the existing IE window.
Note: I am using a keyword driven framework written in java.
From the IBM RFT online help: You can use the loadURL() method of the browser object.
If you do not have the browser object already 'learned' into your object map, just record a click on the browser toolbar. Then you can modify that line to be Browser_htmlBrowser().loadURL("http://stackoverflow.com");
Thanks Tom. I agree that loadURL has the implementation to do what I need.
There is one more aspect that may interest others looking at this question, i.e. the way the appropriate browser object is captured. Obviously the easist way is to use the RFT record and click way, and use the appropriate recognition properties or the other way is to implement it is find the existing browseron the fly when the method is called irrespective of recognistion properties etc which may be more useful for some scenarios or frameworks, like it is done below.
RootTestObject root = getRootTestObject();
TestObject[] testobj = root.find(atDescendant(".class", "Html.HtmlBrowser"));
BrowserTestObject bto;
bto = new BrowserTestObject(testobj[0]);
bto.loadUrl(curParamOne);
