This question came on the Ensemble in Healthcare email list. It's a great question. I'm working on an answer, but am posting it here to get any other input. I'll also address the option of using %CSP.REST.

Hello everyone,

Using Intersystems Healthshare/Ensemble, I am trying to make a RESTful Interface between Android/iOS app and Cache database. I have some queries and I am unable to find where exactly I can get any resources on them.

1. By extending the EnsLib.REST.

Greetings! This article describes yet another simple way of creating installers for the solutions based on InterSystems Caché. The topic covers applications, which can be installed or completely removed from Caché with one action only. If you are still documenting installation instructions that have more than one step to do to install your application — it’s high time you automated this process. 

I am trying to execute a system query. - %SYS.Journal.File_Search()

The Query is looking for a Journal File Name and a String.

However, the Query line accepts no parameters. - Query Search() As %Query(ROWSPEC = "Offset:%Integer")

But in the SearchExecute method if checks for File and String.

ClassMethod SearchExecute(ByRef qHandle As %Binary, String As %String, FileName As %String . . .

Our company is looking for someone with expert object script skills and experience developing with REST using Caché. We have an existing application that currently supports a mobile application and a web application. The API is up and running but we need another developer to add new features and keep up with demand.

Experience with Amazon AWS is highly desired as the api is running on Windows in EC2. Familiarity with GitHub is also required.

Pay can be negotiated on a per hour basis after you provide an estimate for the time required to complete a given feature.

I was writing a routine that called some class methods and when I typed in ##class( and the package, there was a drop down list of all the classes that match that package but when I selected one of the dropdown entries it added the package name again.

For example if I enter ##class(dim.

I am presented with a list of classes in the dim package but when I selected one of them,(dim.OccupationList), what ended up in the editor was

##class(dim.dim.OccupationList

Hi!

Want to share with you code snippet of try catch block I usually use in methods which should return %Status. 

{ 
 try {
  	$$$TOE(sc,StatusMethod())
 }
 catch e {
 	set sc=e.AsStatus()
 	do e.Log()
 }

Quit sc 
}

Here $$$TOE is a short form of $$$TROWONERROR macro.

Inside macro StatusMethod is any method you call which will return %Status value. This value will be placed into sc variable.

In case of sc contains error execution will be routed to try catch block. You can wrap any Status methods calls in your code if you need to catch the errors coming from them.

I am using java gateway imported/proxy classes and JG business service. I need to load a dll at run time.

I use System.loadLibrary/System.load when in java. I’ve tried $ZF(-3,” C:\Windows\System32\pteidlibj.dll”) and $ZF(-4,1,"C:\Windows\System32\pteidlibj.dll") but I’m getting <DYNAMIC LIBRARY LOAD> error.

How can I load a dll at run time using COS?

I have a class which, in the previous instance, was able to extract metadata field names and data from a text file, and load this information into a domain. I am trying to run this in the field test instance, but it is not loading the metadata - only the field names. I am not getting an error, but the data is not loaded.

The few changes I made to the original class:

Previously, this class also ran iTables. I commented all that code out.

To create the domain, I replaced the line:

  set tSC = ##class(HSTA.DomainExpert.utils.DomainUtils).%CreateDomain(dname,.

I have a scenario where I am calling a business operation which populates  and returns an EnsLib.SQL.Snapshot via dynamic SQL to a Business Process. I then want to iterate over this snapshot and call a RecordMap Operation to write those records to a delimited file.

Is this the correct way to do something like this? If so, does anyone have a sample which illustrates its correct usage?

When the snapshot is returned I save it into a context variable with:

set context.Snapshot=callresponse where the pOutput variable of the operation is set to EnsLib.SQL.Snapshot.

We are in the process of putting a new UI on the existing product documentation, including a mobile-optimized view. We also plan on releasing additional "solution based" documentation that is targeted at common usage scenarios or important configuration tasks.

We are interested in your feedback on our current product documentation - what you like and dislike and especially what changes you would expect to see to make it as useful as possible.

You may experience errors executing Java programs that rely on the JAVA_HOME environment.

For example when Create PDF from this pivot in DeepSee or in this case, outputting a Zen Report as PDF.

You can verify the PDF generation configuration by clicking on the Verify Now button on the Management Portal System > Configuration > Zen Report Settings page:

Outputting a Zen Report as PDF causes an error, for example ZENApp.MyReport.

2015.2.3 Maintenance Release

Zen Mojo 1.1.1 released

I'm used to using Class/Refactor/Override in Studio to override methods, properties, xData blocks, etc regularly.

I can't see how to replicate that in Atelier at the m moment. Is this possible ? 

During the Unconfernce and Sessions during the Global Summit several folks had questions and wanted to see how Ohio State setup our Managed Alerts.  Attached is an export I did along with Documentation I had given to our group here at OSU for Managed Alerts.

Good afternoon, I have working prototypes of each of these approaches. I do not have an expansive cache background.

I have a couple of projects where I am ingesting files from disk.

The name of the file contains a lot of the information I will need to reference the file in the future.

What are the advantages and dis-advantages of these two approaches:

Store the whole filename and use SqlComputeCode to populate properties in a class?

Parse the data out of the filename on ingestion into properties in a class?

For each approach what are the implications to indexing?

Thank you.

Hi,

I sometimes get asked if Weblink will still be available (as a downloadable ad-on these days) for some versions to come. 

I realize that this is old technology now, and that there are better and faster ways to do the same things today.

Thanks

On the class reference %Library.GlobalCharacterStream is marked as deprecated in favor of  %Stream.GlobalCharacter.

How I can migrate the data from class properties defined as %Library.GlobalCharacterStream to the new one %Stream.GlobalCharacter? 

Does the %Stream.GlobalCharacter have the same SQL support from %Library.GlobalCharacterStream?

Thanks.

Hi all,

Do you have a sample to set EnsLib.Workflow.TaskRequest.%FormTemplate point to a Zen page?

I got "ERROR creating application object" when doing so. A simple sample would be appreciated.

Hello,

I am trying to router a custom message using the content of one of its property, but this property is a List. ¿How I can do it?

The rule could be something like this

<rule name="">
  <constraint name="msgClass" value="Test.TestMessage"></constraint>
    <when condition="Document.myList.GetAt(1).property1=&quot;AA&quot;">
      <send transform="" target="DummyOperation"></send>
      <return></return>
    </when>
</rule>

But this rule doesn't compile.

TestClass is a simple Request Class like this:

Class Test.TestMessage Extends Ens.Request
{
Property myList As %ListOfObjects;
}

I have a need to query and retrieve DICOM images using the 'pull' method of C-FIND and C-GET.  I have seen examples in Ensdemo where Ensemble is a target of pushed messages.  Has anyone used Ensemble this way?  If so,  can you share and example?

Hi,  The ZEN Mojo Widget reference at ../csp/sys/%ZEN.Mojo.WidgetReference.bootstrap33xHomepage.cls is a great reference for viewing the different components available with each helper plugin - and it also supplies snippets of JSON code to use in your layout definitions.

I'm having problems with the Bootstrap $navbar component however.

I was trying to modify the REST.DocServer sample in the SAMPLE namespaces to use the new %Object and %Array system objects (Ensemble 2016.2 build 636) with the following changes:

/// This method returns a list of namespaces for this server

ClassMethod GetNamespaces() As %Status

{

    #dim tSC As %Status = $$$OK

    #dim tList,tNS,tFilteredList,tValue As %String

    #; Get the list of namespaces

    Do List^%SYS.NAMESPACE(.

I get NOROUTINE when I try to call a label in a routine in another namespace:

d someLabel^|”OTHERNAMESPACE”|someRoutine(inputVar,.resultByReference)

Two questions:

1.  What is wrong with my syntax for calling a label in the other routine, versus just the root of the .int/mac?

2.  Can I pass a parameter by reference when using extended routine reference?

Hello,

It is time for me to eat my own dog's food and start implementing unit test running with coverage :) I will be inundating IRC with questions at this point, but I have a more general question first.

In this tutorial, it is supposed that your unit tests are exported as XML first... But that's not very practical. Is there a way, instead, to run all tests from a given project without having this export?

My first thought on how to do this would be to:

On the Mac...

I've defined a Cache Connection to my local server. It worked for the last two days, but after an uninstall/reinstall of Atelier, it stopped working. The stack trace has these entries:

java.lang.RuntimeException: Can't read from secure storage node /com.intersys.eclipse.connmgr/ensrc

Caused by: org.eclipse.equinox.security.storage.StorageException: No password provided.

Regardless of the above problem, it made me wonder how I would delete the bad connection, or edit it, to change the Web Server port number for example.

Hi,

Is it possible to have a ZEN Mojo application that uses Bootstrap and controls from jQMobile ?

In a fresh installation running Zen Mojo version 1.1.1, my ZEN Mojo page declares:

Parameter CSSINCLUDES As STRING = "bootstrap-3-3-5/dist/css/bootstrap.min.css,jquery.mobile-1.4.5.min.css";
Parameter JSINCLUDES As STRING = "jquery-1.10.2.min.js, jquery.mobile-1.4.5.min.js,jquery-1.11.3.min.js,bootstrap-3-3-5/dist/js/bootstrap.min.js";
..

and a pageContents of:

XData pageContents [ XMLNamespace = "http://www.intersystems.com/zen" ]
{
<pane xmlns="http://www.intersystems.com/zen" xmlns:mojo=

The recent post about help with the Cache Language and the responses were very helpful.

I suggest two new tags, and the tags being permanently toward the top of the tag list.

1) Help with understanding the Developer Community

2) Help with Cache and all the various off-shoots 

Hello,

Still related to the unit test with coverage support project, one goal is to make that package available to everyone.

One possible way I already know of is that all fully qualified class names (ie, the package + the class name) start with %, which mean that on installation all classes will end up in the %SYS namespace, but this requires that the install be done as a user with the necessary privileges to write to %SYS.

This is rather convenient in my situation, sure; but is there another way which does not require such privileges?

Getting around to wrapping up a short tour in Professional Playtime, I wanted to share my experience at the HIMSS FHIR Connectathon I participated in out in Indy in April.

A quick note about the venue, aside from the sponsors, and those who put this thing on... great job.  The venue was amazing, hosted by/at the beautiful campus of Eskenazi Health and in a city that really gave a damn about innovations in our space.  The food was great, the caffeine was continual, and was even rescued by the great host Brian Norris
