Hi Mark.

I don't know where "undefined" word comes from on the trace, but when %XML.Reader reads empty element it reads it as character with code 0 -- $char(0), that corresponds to empty string in SQL:

Class Community.Test Extends (%RegisteredObject, %XML.Adaptor)

Property StatusLastChecked As %String(XMLPROJECTION = "element");

ClassMethod test()
        set xml = "<root><Test><StatusLastChecked></StatusLastChecked></Test></root>"
        set reader = ##class(%XML.Reader).%New()
        do reader.OpenString(xml)
        do reader.Correlate("Test","Community.Test")
        do reader.Next(.obj)
        zw obj


USER>do ##class(Community.Test).test()
obj=3@Community.Test  ; <OREF>
+----------------- general information ---------------
|      oref value: 3
|      class name: Community.Test
| reference count: 2
+----------------- attribute values ------------------
|  StatusLastChecked = $c(0)

So in your code you can compare with $C(0).

Also for details on handling empty strings, see following section in documentation:

Handling Empty Strings and Null Values

Hi David.

Source code for EnsLib.FTP.InboundAdapter is available in the installation.

EnsLib.FTP.InboundAdapter calls method %Net.FtpSession:List to get files. And that method uses "LIST" command.

EnsLib.FTP.InboundAdapter:OnTask executes following resultSet to get files:

Set tSC=..%CurrResultSet.Execute($this,..FilePath,..FileSpec,..SubdirectoryLevels,$S(..%isSFTP:"FileListSSH",1:"FileList"),..SemaphoreSpec)  Quit:$$$ISERR(tSC)

And in OnInit, ..%CurrResultSet is initialized as follows:

Set ..%CurrResultSet=##class(%ResultSet).%New($$$CurrentClass_":DeepList")

Query DeepList is defined in EnsLib.File.Common, and it's just a proxy for the query that is passed as 5th parameter to the Execute -- FileList in this case.

And EnsLib.FTP.Common:FileList calls %Net.FtpSession:List.

What Caché version do you have?

On my 2018.1.3 instance code is following:

// Look for pattern : version "
// where the double quote may optionally be replaced with a single quote or ommitted
Set regex = "version\s['""]?(\d+(\.\d+)+)"
Set pos = $Locate(pOutput,regex,1,,versionWithPrefix)

// Get just the number from the previous pattern :
Set regex = "(\d+(\.\d+)+)"
Set pos = $Locate($Get(versionWithPrefix),regex,1,,version)

Notice -- $Get around versionWithPrefix.

Most likely Caché cannot find java home dir. Specify Java Home Directory in JDBC Gateway Server settings.

Hi Laura.

First question -- what algorithm does openssl_public_encrypt use?

PHP reference [1] and source code [2] says that this is RSA.

So in Ensemble you can use $system.Encryption.RSAEncrypt() [3]

Important thing to note about RSA encryption, is that length of the plaintext can not be greater than the length of the modulus of the RSA public key contained in the certificate minus 42 bytes.

Thanks for sharing Paul.

Though reference article for $username has this documented:

$USERNAME contains the username for the current process. This can be in one of two forms:

  • The name of the current user; for example: Mary. This value is returned if multiple security domains are not allowed.
  • The name and system address of the current user; for example: Mary@jupiter. This value is returned if multiple security domains are allowed.

To allow multiple security domains, go to the Management Portal, select System Administration, Security, System Security, System-wide Security Parameters. Select the Allow multiple security domains check box. Changes to this setting apply to new invoked processes; changing it does not affect the value returned by the current process.
