Many times we come across a situation where we need to know what kind of java / jdk is installed on particular server. It could be the jdk from Oracle or IBM or an Open JDK.
One of such situation I came across was when connecting to IBM MQ channels over SSL from a client where java was installed. However the java client program was not able to connect MQ channels despite all the MQ configurations and settings being correct at the client end and even on the Server end.
Later based on the error codes and after some google search i got to know that if the java client is not running on IBM java then we need to set special arguments. After setting those up it started working.
Here i would like to mention about a simple java command that will provide us the vendor details describing what vendors java implementation has been installed on that particular server. The command is simple but shows lot of information which we would like to know in some or the other situation.
