I have a batch record mapper that reads a csv file and passes the message to a process that uses the EnsLib.MsgRouter.RoutingEngine and would like to pass the message to an operation that will output that as a XML file but so far been unlucky as the operation that I use , uses the EnsLib.EDI.XML.Operation.FileOperation which only works with the messages("BusinessOperation class for writing XML messages to a file.

When starting a post, especially for the beginner there are a lot of buttons, check marks, icons etc. On some of them when you hover you get a very brief descriptions. In reading through some of the responses to the Developer Community Feedback there is a lot of good information.

Could one of the moderators, who know all the tricks put together a one or two page "cheat sheet?" or beginner guide?

This "Cheat Sheet" would be of great help!

I get the impression that there is a great push to encourage others to use the Developers Community.

Posting to a REST service

Hello,

I come from a programming background, but haven't touched ObjectScript before my current job, so please forgive my ignorance.

Within an Ensemble system, I need to post some information to a RESTful web service. I'm just trying to figure out how to create a method which takes a simple message and posts this off to a RESTful web service?

Thanks in advance for any help.

I am trying to capture the write of a method to test the response in an unit test. I know everything works because one of my colleagues ran the code and did not froze on his machine.

I don't what is the cause of the freeze. I know that at line Use $io::("^"_$ZNAME) it stopes because i have put some write functions after every line in WriteCapture method and i only saw the first write function in terminal

I also used debug and in this case it didn't froze

Greetings,

Is it possible to save Cache code into a file and then run it via command line?

IE: csession [ini] -U [ini] /path/cacheCodeFile.?

What I need to do is run a Cache script from the Linux command line. The script will navigate data to produce a file and then it will exit back to the command line.

Thanks in advance for everyone's time.

I need to check if one class is a subclass of another (either direct or indirect).

For example:

Class Package.ClassA Extends %Library.Persistent
{
}

Class Package.ClassB Extends Package.ClassA 
{
}

Class Package.ClassC Extends Package.ClassB
{
}

In this example Package.ClassC is a subclass of 3 classes: %Library.Persistent, Package.ClassA, Package.ClassB.

So any of these checks should return 1:

Hi!

I am not system admin. But it used to be very simple to install CSP Gateway on an apache system on Linux with Apache installed. I used to run the CSP Gateway installation program and after it was done, all I had to do was fine tune some configurations on CSP Gateway portal on http://<ip>/csp/bin/Systems/Module.cxw and I was up and running.

AES Encryption

Trying to use AES encryption for a url. I have a plain text string, a 16-byte key and a initialization vector. I am trying to match a C# implementation that uses RijndaelManaged class with a BlockSize = 128, Mode = CipherMode.CBC, Padding = PaddingMode.PKCS7. The output of the $SYSTEM.Encryption.AESCBCEncrypt(text,key,IV), doesn't match what is coming out of C#. All inputs into the $SYSTEM.Encryption.AESCBCEncrypt(text,key,IV) are converted to UTF8 as in the documentation.

I'd like to access and view the soap log. Apparently there is a global for that (^ISCSOAP) (http://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY=...), but insofar I have been unsuccessful finding the exact cache command for viewing the soap log or changing it so that it logs both incoming and outgoing traffic. Can anyone enlighten me?

I.e. I am trying stuff like:

set ^ISCSOAP("Log") = io

write ^ISCSOAP("Log)

Good day, every process in my software is about to update 3 specific globals in row when the process is called to do some job. I need to guarantee that during updating of those globals with multiple processes there is only one process that is actually working with those globals. Moreover I need my globals unreadable if other process is in critical area.

Example:
