PowerBuilder 2022 Customer Beta Released!
Thursday, May 19, 2022
STD Framework - PowerBuilder 2021 to Java!
** New Feature **
STD Integrated Framework
PowerBuilder 2021 to Java Interoperability!
Software Tool & Die Inc. are pleased to announce the release of the updated PowerBuilder to Java interoperability example application (PB2Java)! The updated PB2J example (2022R1) application is also built from the latest STD Integrated Framework (version 2022.2.0.185 released on 2021-01-16) and the newest Appeon PB2021 release (build 1509).
Now the ability of a PowerBuilder native based application to
"consume" a Java class and call its methods is even easier than before
and totally encapsulated into the STD Integrated Framework for PB developer productivity!
The PowerBuilder IDE since early 2000 has had the ability to call
EJB (Enterprise Java Beans) due to the introduction of the Java based
Application Server by Sybase named EAServer. With EAS came the
ability to call a remote EJB in any J2EE based application server by
using RMI (remote method invocation) that was exposed as the "Home"
interface. The EJB Home Interface though can be either local or remote
in nature. Thus when dealing with a native MS-Windows PB application
that has Java classes deployed along side of it, we can use the local
Home interface to interact with it from a PB application. This is, as
long was we expose the Java application as an EJB (that is .. follow the
EJB construction rules).
When the Java developer creates a Java class, they can also create a
Home interface or what PowerBuilder would refer to as an EJB "proxy". A
Proxy is a Class/Method signature that allows PB to treat the Java
application as a "bean". According to the generally accepted definition
of a Java proxy is as follows: "A proxy class is a class that implements a list of interfaces". Since
CORBA (Common Request Object Broker Architecture) support was added to
PowerBuilder a long time ago - PB understands "proxies" very well. So if
we can get your PB application a list of proxy classes it needs to deal
with an EJB, it can then communicate with it. First of all, we can
build a Java Class and then build a HOME interface for that using your
standard development environment - even "notepad" for us poorer folk.
Once completed, you can just compile the EJB class and its Home class
using the JAVAC compiler, as follows:
Now that we have an EJB and a Home class to serve as a "proxy"
road-map for PowerBuilder, we can use the Classic IDE to build the
necessary interfaces for us in a PowerBuilder Library (PBL) to use in
our application. To perform this step, we need to call on the IDE's
Project Painter to help us with this task. When creating a new project,
we can then select EJB Client Proxy option. This will build a a
PB Project object that can build all the necessary proxy interfaces for
you. All we need to do is specify the Java Bean class and its HOME
(interface) class to the proxy painter. for example:
Once the EJB Client Proxy project is properly configured, the next step will be to run the project, as follows:
Now that we have the "proxies" required for the Java interface
(Home) class, we can now instantiate the EJB by using its proxy in your
PB Application. The only challenge beforehand, is loading the Java
Virtual Machine (JVM) and activating its JNI (Java Native Interface) JDK
to inter-operate with your Java EJB. Luckily, this is where the STD Integrated Framework steps in to help you. All you need to do is call a new "of_create_instance" method in the Application Controller supplied by the framework and it will perform all
of the JVM the house keeping for you including: loading, reusing,
unloading, garbage collection, etc of the PB to JVM infrastructure! So
now the PB Developer can just concentrate on using the EJB's methods
& processes, for example:
To make this easier to follow, STD have created a working example of
this PB to Java mechanism for you to examine, learn and move forward
with your organizations Java interoperability within your PowerBuilder
project. You can download the PB2Java example built from the STD
Integrated Framework by clicking here!

| Base64 example from an ANSI text file! |
Base64 encoding and decoding is a critical feature
when processing XML and JSON files that contain binary
datum. As well as using PowerBuilder's PBDOM feature, an XML DataWindow
or interacting with Web Services that pass binary data
back and forth (ie: JSON in a RESTFul web service). The received binary
data will be in base64 encoded format - which is unusable
to your PB application unless decoded (converted back) to its original
binary state. Conversely, binary data that your PB application needs to
send to other XML or JSON based applications must be converted
(encoded) into the base64 standard.
 |
| PowerClient based Base64 example using Unicode text file! |
 |
| Error handling for corrupt (incomplete) or wrong encoded Base64 files. |
The Base64 Example application utilizes standard Microsoft Base64
API's supplied by the MS-Windows O/S. These API's are now embedded in the
framework's "nc_crypto_master" object class and easily called from your
PowerScript code, as follows:
- lo_crypto.of_base64_stringtobinary ( lblb_image , ls_base64 )
 |
| Base64 file translation into an image (or any other binary format for that matter)! |
The latest Base64 Example - along with the STD Integrated Framework is also able be used with PowerClient and PowerServer (Cloud) applications. Thus, the Base64 Example application can also be deployed to your favourite Web Server for convenient deployment.
You can download the Base64 Example application from the STD Framework's website by clicking here! You can also download either of the free open source STD frameworks for PowerBuilder, InfoMaker and PowerServer2021 by clicking here!

STD Framework - PowerServer 2021 Console Updated!
Hot News!
PowerServer 2021 Console Application
Built using the STD Framework!
Software Tool & Die Inc. are very pleased today to announce an updated version of the PowerServer Console (2022R1) application for use with the Appeon PowerServer 2021 App Server! This latest release of the PowerServer Console application that is all written in PowerBuilder 2021 and is also using the latest STD Integrated Framework (2022R2 Beta) ...
In the original release, the PS Console App could only monitor and if need be kill a PS2021 App "Session". Changes in this release also include:
- Migrated the App code from PB2021 build 1288 to PB2021 build 1506
- Replaced STD Integrated Framework from v2020.2.0.160 with v2022.2.0.185
- 20% better performance using the 2022R2 framework!
- PSConsole.Log file automatically deleted at EOJ (unless App errors out)
- Incorporated new MS-Windows notification utility that is now multi-threaded
- Updated the Theme files to PB2021 build 1506
- Tested the Base64 code on W10 version 21H2 build 19044.1645
- Tested the Base64 code on W11 version 21H2 build 22000.613

| PS Console App monitoring PowerServer "Sessions". |
Tip: The only tricky part of the coding for the PS Console App's RESTFul web service session interaction was that the PS "DateTime" comes back with Time Zone data attached in JSON format that unfortunately PB cannot handle JSON wise. So I had to strip the TZ information off in order to import the DT into a DWO's DT column type. However, PS's DT is GMT and thus the actual time is off compared to the PC's time. I will look into this deeper for the next release & try to compensate.
One of the next new features in this PS Console release now allows you to see the API's within the PS2021 server itself by using the new API tab page. Note that the PS2021 Console's functionality is governed by the built-in exposed "internal" RESTFul web services within the PS2021 server itself. Check out the new API documentation feature display, as follows:
 |
| PS Console displaying the RESTFul API's in PowerServer 2021! |
The next new feature in the latest version of the PS Console is the ability to check the PowerServer's actual Heath. You can do this by selecting the new Health Tab in the PSConsole application, as follows:
 |
| New PowerServer Health check feature at work! |
I have also recently updated the STD Integrated framework to handle PS Server outages without crashing the running PB App running with PowerServer. This allows the App User and/or Support team to see exactly what happened in a PB/PS App failure when its related to a PS2021 issue, Network failure, Server not started, Killed session, etc type of failure.
You can download the PS2021 Console and OrderEntry Demo App for PB/PS2021, as follows:
PS Console: Download
OrderEntry: Download (latest Beta)
