Reg: Storing a value into variable and passing to next job or componen

[Anonymous]

Hi All,
In my mapping I generates a value dynamically, I have to store this value in to a variable and pass it to a tMysqlRow as context. How can I do this in Talend? Currently I am doing this by writing a value to a flat file first and reading the value as a context from flat file to tMysqlRow. This one looks like over work to me and I want to scale it down by a better solution. Can any has an answer for this?
Thanks
Naju

Hello
You can store the value in a context var or global var, for example:
context.name="newValue"
or
globlaMap.put("name",value)
on next subjob, get the value by:
(String)globalMap.get("name")
Best regards
