Hi,
This is regarding third party software JDK 1.6 used in power builder  IDE. we need information on which functionality uses JDK 1.6 in Power builder IDE.
 
As per the appeon documentation at (Documentation link : https://docs.appeon.com/pb2017r3/application_techniques/ch35s06.html), the JRE is required for EJB clients, JDBC connections, and saving as PDF using XSL-FO.In Our application,
 
we are not using the above areas. We would like to know
  • 1. Is there any other areas JDK is used in PB IDE.
  • 2. Would it possible to run/build using the IDE without the jdk or the pbjvm190.dll if we are not using the documented areas.
Regards,
Harikrishna.S

Hi Sreerama;

  In addition to your list, the IDE can also engage the JVM when communicating to a Source Code Manager (SCM) that is Java based. Armeen is also correct, that the JVM is also used when calling Java Classes from a PB App. For example: http://chrispollach.blogspot.com/2019/09/pb2j.html

  BTW: You do not need to use the JVM that comes with the PB IDE installation. For example, I am using ...

  FYI: You can also turn off any JVM usage by the IDE by adding this to your PB.ini file ...

; Disable the JVM

CreateJavaVM=0

Hi Harikrishna,

JRE is only required by features of PowerBuilder that uses Java.  If your application is not using the Java features you mentioned, then JRE is not required.  

Best regards,
Armeen
