Pass data from one component to another in adobe CQ

Question

I\'m using Adobe CQ5. I have made two components that are independent of each other. However, I want to use data from one component in the other one. How do I achieve this?

Answer 1

There are a number of options, depending on how closely the components are coupled (e.g. will both always be placed on the page at the same time? Are they hard-wired into the template, or placed by the editors, etc.)

If both components are on the same page, the simplest is probably to set a variable within one component & read it in another, e.g.:

foo.jsp

bar.jsp
