How does one use a different JVM under Windows with broker 5 csd6.
I have Java 1.4_02 installed as my system JVM but it would appeat that the Java 1.3 VM that comes with broker is being used.
How can I point it to use another JVM.
The doco talks about creating symbolic links on Unix to do this, but how does one do it on Windows? |

Why do you want to do this.

I don't think you can, because the Windows version supplies the JVM, where the Unix version "points" at an installed version.
Cheers,

You can probably just replace <Broker installation>\jre\ with a 1.4 jre.
But you'll lose support for realtime transport.

I wanted to use the javax.xml DOM apis in a plugin node. These however are standard only in Java 1.4.
However I figured that broker itself mist be using these APIS itself to some extent and after some digging around I found that there is a xerces.jar and java-xml.jar in the brokers classes directory.
These jars contain the javax.xml.* APIs I needed and I could move forward.
But say I wanted to use a Java 1.4 feature that is not easily available, I figure I would have to some how change the JRE. While out production environment is AIX, our development environment is Windows. |

The java API for XML (JAXP) was optional in 1.3, it was brought into the core for 1.4.
Some code requires java 1.4, although most works on 1.3. There are also a few backporting projects, the main example is logging which has a backport from 1.4 to 1.3. |
