when running gsk7cmd (AIX MQ7) I get
| Quote: |
Error:
java not found.
JDK 1.3.1 or later required.
Please set JAVA_HOME or add directory containing java to path. |
PATH:

Sorry about that. I found:
| Quote: |
| AIX® export JAVA_HOME=/usr/mqm/ssl/jre |
and now it works. |

Learn as well that for the JAVA_HOME variable you never set it to the executable level... setting it to /usr/java5 like
| Code: |
| export JAVA_HOME=/usr/java5 |
would have worked as well.
Have fun

fj, can you qualify why please?
The Info Centre states:
| Quote: |
| You must set the JAVA_HOME environment variable to /opt/mqm/ssl/jre. |
I have a very low level of java expertise and with the emphasis of 'must' above, I'm curious to know why. Thank you.

You need to use the Java runtime that comes with MQ in order to get all of the security algorithms and etc. Things like AES do not come with an out-of-the-box Java install.
So that's why the infocenter says MUST.
And that's why it specifies the path to the jvm that is shipped with MQ, and points at the directory that holds the whole JVM and not at the specific java program.
FJ is making a clarification between pointing JAVA_HOME at /opt/mqm/ssl/jre/bin/java (which is the executable) and /opt/mqm/ssl/jre (which is the directory that holds the Java install). |

You mean to say that the JSSE/JCE package shipped with standard java, and the one shipped with MQ are different, right?

Yes, that is likely what I mean. |
