You could also use a regular expression with the %Regex.Matcher class

set regex = ##Class(%Regex.Matcher).%New("(/w)*")

The "/w" refers to any word character include alphabetic, numeric, and connecting characters).  This is wrapped in a grouping expression '()' and finally the * say match 0 or more occurences.  

You can then examine the GroupCount and Group multidimensional properties to see the results.

As someone else indicated applications will normally have a configuration page for the driver.  

In dBeaver for example when you setup a connection there is a "Driver Settings" button 

Clicking on this will allow you to configure a JDBC driver for connecting.  To start you would go to the libraries tab and point at the InterSystems JDBC jar file as shown below.  Your path would look something like c:/InterSystemsJDBC/intersystems-jdc-3.2.0.jar (your folder may be different).

Finally on the Settings tab you would indicate the class name and other connection settings

If you are trying to connect programaticaly you can use whatever library you wish and provide the same type information.  Here is an example in Python using the JayDeBe API library.

    IRIS_JARFILE = "c:\JDBCdrivers\intersystems-jdbc-3.2.0.jar"
    IRIS_DRIVER = "com.intersystems.jdbc.IRISDriver"

    JDBC_JARFILES = [IRIS_JARFILE]
    # Database settings - this should be in a config file somewhere
    # credentials.MyCreds = ["username","password"]
    dbConn = jaydebeapi.connect(IRIS_DRIVER, 
      jdbc:IRIS://10.17.10.84:1972/B360",
      credentials.MyCreds, JDBC_JARFILES)

You can also use the iris.system object in python. 

iris.system.Version.GetVersion() returns the full version ($ZV)

IRIS for UNIX (Ubuntu Server LTS for x86-64 Containers) 2022.2 (Build 356U) Thu Oct 6 2022 22:56:28 EDT

There are other methods here to call to such as GetMajor() which would return '2022' and GetPlatform() which returns 'Ubuntu Server LTS for x86-64 Containers'

do dir(iris.system.Version) at the python shell to see them all.

Careful with the 'objectscript.export' folder setting.  This needs to match where, under the root of your VScode project, your source lives.  For example my settings are:

        "folder": "iris/image/iris_src/dev",
        "addCategory": true,

So under my VScode project folder I have the path indicated in Folder.  This is how my git repository is setup.  Now my 'addCategory' is also true.  Therefore under that /dev folder I have sub-folders for 'cls' and 'rtn'.  All my classes should be under the 'cls' folder and any routines are under 'rtn'.  There are other sub folder too for other elements, but you should get the idea.

To add to the puzzle there is also the setting "objectscript.export.atelier".  With this setting true the plug in expects each package and sub-package to be a separate directory.  So if I have a class Example.code.test what you will end up with is a path, given my setup above, under vs code that looks like this.

iris/image/iris_src/dev/cls/Example/code/test.cls

If the file whose definition you are trying to get to is not in the right place it will open it in read-only mode from the server when using Client-side editing

Prudhvi,

The simplest answer is no.   ZEN, which has been a deprecated technology for some time, is a complete framework deeply integrated to Cache.  It relies heavily on synchronous communications which has been deprecated by, thought still available, by most browsers.  For both reasons new development should not be done using ZEN.

Angular, on the other hand, is a modern framework for Web Application development.  It is inherently asynchronous and therefore disconnected from the back-end.  As Eduard stated the typical communication methodology is for the back-end to provide a RESTful interface which are quite easy to develop and publish both direct from IRIS or via the InterSystems API Manager.

I am going to make the assumption that this is part of an existing application that you are looking do new development on.  As stated ZEN is deprecated therefore it would be a good idea to develop a roadmap to migrate from ZEN to something like Angular.  I would take this new project and use it to explore the move to Angular.

You should also note that at some unknown point in time browsers could remove support for synchronous communications.  The latter will likely not happen for quite some time as many older applications still rely on it.  Several years back one browser, Firefox I think, tried to remove this support and had to quickly backtrack as too many applications stopped working.  So you have time.

Aaron,

In my experience you need to purchase the schema.  You can go to http://x12.org to find out more.  Depending on your usage and needs it can be a bit pricey for licensing especially if you only need one schema.  If you have a partner that has access you could piggyback on there license assuming you have a working relationship with them.  Unfortunately I did not see any option to purchase just a single schema, though there was something like that in the past as I have a colleague that did so.  You can try to contact the org to inquire.

Rich Taylor · Jun 15, 2022

There is no general rule-of-thumb.  It really depends on the nature of your application and usage patterns.  For example if this is primarily a REST based service I would set the maximum to your license capacity minus a reserve for administrative functions, background tasks, and reporting.

In a mixed environment you need to have a more balanced setup of REST (web) calls versus direct connections.

As I indicated you really need to have an idea of the use patterns of your application.
