I am failry new to WMB and im from java background..
In java we use reference variables we pass reference and make changes on the original object.
In WMB i would like to do the same thing.. i would like to modify two reference vairables and get back the modified refrence objects.
I dont know how to intialize them finally after lot of struggle i found this
| Code: |
DECLARE abcRefNonNull REFERENCE TO env.Variables.TEMP;
CALL setnotnull(abcRefNonNull , inroot); |
I want to have two or three varibles like this...but all of them refer to TEMP if i use the same as above ...i dont want that...can anyonr please please please help....

You can't.
ESQL is not an object orientated language. The reference variable is a reference to a location in one of the broker maintained message trees not a discrete object. You can modify the location the reference points to, and you can move the location being pointed to, but you're still referencing a message tree (the Environment tree in the example you quote).

There's no TEMP variable supplied with the product; this is something you've defined for yourself. You can define as many as you like, and can place them in any of the supplied message trees according to how you intend to use them or in your ESQL code if you wish.
I repeat; you're not using an object, you're using a location.
