How to get a .cls file in a server directory and download it to the client side

I need to get a file in a directory and when clicking on the download button, this file will be downloaded on the client side.

%Status usage in ObjectScript

Hi developers!

Want to discuss with you the case of %Status.

If you familiar with ObjectScript you know what is it. I'd love to hear the history of the case why it had appeared in ObjectScript but it turned out that almost every system/library classmethods return %Status and there is a whole set of tools to deal with it.

What is does it gives you the responsibility to check the value or %Status of every system method you call.

E.g. if you save the data of the persistent class,  you should never call like this:

do obj.%Save()

you need to call:

set sc=obj.%Save()

if $$$ISERR(sc) do // something or quit.

Develop integration service

The InterSystems IRIS has an integration engine with these core elements:

1. Adapters: are inbound (data/message input/request) and outbound (data/message output/response)  integration logic specialized in the type of data or message protocol (file, http, etc.). They are the interface to allows connect with source or target data repositories or systems.

2. DTL: is a component to mapping and transform data between two components in the flow orchestration.

3. BPL: is a component executing BPEL language to execute integration/orchestration flow.

How to share resources among Csp Process?

I want to call some Java Remote Call through Java gateway.  The call code as following:

class CallRemote Extends %CSP.REST {

Method Index() as %Status {

Try

      set gw = createJavaGateway()

     Do callJavaMethod(gw)

     do gw.%Disconnect()

Catch {

}

}

}

But Every call need connect to Java Gateway and disconnect it. But It's cost too high( about 80ms)

So, According to my Java experences, I need create some connection and put it into global static ConnectionPool

But I don't known how to reach that using ensemble.

Maintaining job id through multiple webservice calls

I've run into an issue where job IDs are being retained through multiple calls. My team is doing a rewrite of our system that allows VB6 apps and web apps to directly interact with our Cache databases.

The new process has those applications calling into a WebAPI which then calls into the routines.

In one example of the issue we're having, the VB6 app calls into our api which then does the routine call.The Cache routine I'm working with has a load linetag that loads data into a temporary global called ^SORT($J).Upon completion, the process returns back through the api and the VB6 app.

Unit Testing Naming Convention

Hi Developers!

Recently we discussed the naming convention on packages we deploy and even made some choices.

Here I want to have a conversation on the naming convention for unit tests.

Of course, we wish every good library has unit tests. Here is the documentation and some good articles(one, two, three) regarding it on the Developer Community.

Let's decide on the naming of UnitTests packages?

The suggestion is that unit test classes will all start with the UnitTest package name.

E.g. if your library's class name is:

johndoe.lib.class

The related unit test class will be:

UnitTest.johndoe.lib.class

What about folders?

The suggestion is that unit test classes will live separately from source classes, e.g. in /tests directory.

Here is the example of a repository with unit tests that are named and placed according to the proposal.

What do you think?

How to force the CreateBusinessService method to use the FilePath in the adapter settings?

A BusinessService XYZ is created by extending Ens.BusinessService and the ADAPTER is set to EnsLib.File.InputAdaptor. Files are copied to the FilePath specified by the adapter. But if XYZ is invoked directly via CreateBusinessService, the files MUST be deposited to the default temporary director rather than the file path specified in FilePath of the adapter. Is it possible to the use the file path in FilePath when using CreateBusinessService?

HTTP request to get around Kerbos/NTLM authentication error

Hi:

I have the following method in a buisness operation that works on localhost but not on our server . I think it's how the firewall is set up but i was wondering if there is a known way around this. It can't correlate XML as it returns a "The browser did not send any authentication information" error. I tried adding in username and password to http request to no avail. We could do a c# proxy on a server but i'm wondering if there is a known way to fix this error within intersystems. As a developer we don't have too much control over our Intersystems TIE server.

Where can I download the XSD (XML schema definition) of files exported by Cache Studio ?

When you export entities like classes, routines, globals in Cache Studio, you usually end up with XML files that looks like this : 

<?xml version="1.0" encoding="UTF-8"?>
<Export generator="Cache" version="25">
    <Class name="base.monitoredpage">
        <Abstract>1</Abstract>
        <Super>%CSP.Page</Super>
        <TimeCreated>63439,41357.461462</TimeCreated>
        <Parameter name="ENCODED">
            <Default>0</Default>
        </Parameter>
        ...

I was wondering if the XSD (schema definition) of those files are available somewhere (eg : in Cache InterSystems website).

SNMP Service can't connect with Caché SNMP agent

Whenever the Windows SNMP Service restarts, the snmpdbg log says the following. 

13:08:59 :Attempting initial TCP connection(s) with 1 Cache instances ...
13:08:59 :Get connection with ENSEMBLE on port 1972
13:08:59 :Connection refused on port 1972, check if Cache instance ENSEMBLE is started.
13:08:59 :Cache iscsnmp.dll initialized for 1 configs

Ensemble and all productions are running. I've set up Caché SNMP agent on many other servers in our company and those are working fine. However this one server won't budge. 

Does anyone have any idea what the problem may be here?

How do you store, then find and insert example functions and methods into your programs?

Hello developers!

Share the best practices: 1) saving frequently used code sections, 2) quickly finding it, and 3) quickly including it into the current program? There was a thought for 1,2 to use DC(this resource), but the search is not always convenient not only for me

The idea on the surface is to use the git repos wiki. Are there any other best practices?

There is a project github awesome. Maybe we should include the awesome-objectscript sections in it? And in the future for vscode to develop a plugin for awesome-objectscript ?

IDX Groupcast system from Cache'

Hello,

I posted in another thread a short while back regarding accessing (extracting) data from the Cache' database.

I am now told that the (healthcare) system is IDX Groupcast. The kick off project has not started yet but I would like to do some 'homework' and see the data model. I couldn't find too much about this in a Google search. Would anyone have a link or advise for doing some preliminaries? I am already versed in SQL server.
