You can only use array instead of list of exported elements.

USER>zw list
list("a(1).gbl")=""
list("a(3).gbl")=""

USER>d $system.OBJ.ExportToStream(.list,.stream)

If you have an access to WRC, you can get FieldTest versions, Caché and Ensemble with test license keys. If not I think you may ask for an account by sending email to support@intersystems.com

Whats the strange question?

Are you know meaning for two of this words ?

Caché - it's an InterSystems database, platform which you are working on

and cache -  which is just a technology, it is a bunch of ways hardware and software how to return previously accessed data more quickly 

To support Raspberry Pi, IntersSystems should support ARM, but not sure that so easy, and could be valuable for them, even if remember how quickly  they ended GlobalsDB. But GlobalsDB was a quite good product, and was used in some projects, and even still used. If somebody needs to use micro-pc they can use some alternatives on Intel's process such as Intel Galileo

What exactly do you want to reach, authentification in Caché using LDAP login, or you want to connect and load users from AD ?

Closing Tab in the browser, does nothing on the server side, because in simple way, browser only ask server by user's requests.

You can only do some ajax request just when user closes the page, to close session on the server side, no more.

Every session will be alive in their Timeout, that Timeout could be get by default from settings, or you can set it programmatically ( set %session.AppTimeout=900), and only when timeout is exceeded the used grace period 5 minutes. And only after that session and license will be released. 

And you should remember, that if user closed tab, he can open it again, and it will be the same session as before.

Your version of Cache is unsupported, you should have at least 2016.2

Looks like you want to achieve something else, and on the wrong way.

any way you can get the same output as in zwrite to array of lines, with command

Do DumpObjectToArray^%occRun(obj,.lines)

If you have to restore some object by this data, you have to use serialization, XML for example. For xml I would recommend to look at this part of the documentation.

It is not so easy, as you may expect, you should look at some tools like Phonegap and so on

Looks like, you do not know about %Installer.Manifest.  You can use it in any different ways, be it installation new application or just simple changing instance's settings. With this manifest I'm building installation archive with project, it includes deployed code some data, and web sources. I'm installing new server with it, manually, or even with docker. And you can use internal Task Manager to run this installation by schedule automatically. You may also look at this project - GitHubCI, it helps to deploy application automatically just after commit to your github repository.

I think you should look at class %SYSTEM.Encryption where all encryption placed, and at the method $system.Encryption.HMACSHA() 

Since so big difference between this versions, and you may caught many incompatibilities, I would very recommend to install  new instance and move all your data and settings from the old one. And then check everything in your application very carefully.

You can look at the documentation here online

and excerpt about custom installation

The Caché installation program allows you to select certain Caché components to be installed on the computer. For example, you may want to install only the Caché SQL Manager. Keep in mind that some selections require that you also install other components.

and about standard installation

The standard installation procedure installs both Caché server and client components on the computer.

Such error you can face on a windows as well. Your super port has already in use by another instance of Cache. And you can change port for new instance, by editing cache.cpf file in the root of installed Cache. 

To be sure that port is in use you can use some network tools, such as netstat

netstat -na | grep 1972
tcp4       0      0  *.1972                *.*                    LISTEN

or lsof, which can show which process with pid uses this port

sudo lsof -i tcp:1972
cache   14960 cacheusr    4u  IPv4 0x768e107dffb0f4df      0t0  TCP *:1972 (LISTEN)

I did not show how you made connection to the Caché, and looks like, your Java application has hardcoded login password which used to connect to server. 

so, I may only suggest, that you use code like this

Class.forName ("com.intersys.jdbc.CacheDriver").newInstance();
CacheDataSource ds = new CacheDataSource();
ds.setURL("jdbc:Cache://127.0.0.1:1972/SAMPLES");
Connection dbconn = ds.getConnection("_SYSTEM","SYS");

Last string is Caché login password, so you should use here user's login and password. Any works from your application should be with user's login.

You can use $order to order all users, in global

set FF=""
for {
  set FF = $order(^Users(FF))
  quit:FF=""
  set isAllowed = $get(^Users(FF, "SETTINGS", "isAllowed"))
  write:isAllowed !,"User ",FF," is allowed"
}

As I remember, you could create user TRM or TELNET, with routine %PMODE, and will get access without authentication.

Don't remember how it was in 5.0, but currently default login/password is _SYSTEM/SYS

UDL format is for classes only, and this format how that classes looks in Studio.

Export web files, available as any others in XML format with $system.OBJ.Export()

USER>d $system.OBJ.Export("/csp/user/*.*","export.xml")

Exporting to XML started on 08/24/2016 20:52:44
Exporting CSP/CSR or file: /csp/user/ML_Util.js
Exporting CSP/CSR or file: /csp/user/menu.csp
Exporting CSP/CSR or file: /csp/user/showsource.csp
Export finished successfully.

And all web files stores as files in the directory for this web-application, so you can get it directly, but native export/import works only in XML

You should not read stream which you got from request, just pass it to $fromJSON, because it understand streams too.

• Macros - a part of the ObjectScript compiler that converts macro code into usable Caché ObjectScript code.
• Routine - a callable block of user-written code that is a Caché ObjectScript program.

Documentation about $horolog 

Contains the local date and time for the current process.

Why do you name it macro ?
Maybe you mean MAC routine ?

I highly recommend to read this tutorial about CacheObjectScript

usually you can call routine by simple command

do ^routine

but sometime you need to call directly to concrete label in that routine

do label^routine()

but in this case if you use curly brace style, you should public such method in routine

label() public {
 write "Hello World!"
​}

or in old style

label()
 write "Hello world!"
 quit
