Question

I am looking for a way to enable aspectJ load time weaving dynamically, say based on whether a JNDI property is true.

Basically, (context:load-time-weaver) have this tag conditionally.

Any quick way to do this?

Answer 1

Have a look at Spring profiles:

<beans profile="production">
    <context:load-time-weaver />
</beans>

If the profile name is production, LTW will be enabled. Otherwise the whole inner block is ignored. I am not sure if profile can be set using JNDI variable, but there are multiple other approaches, e.g.: JVM property, environment variable, web context parameter or you can set them programmatically.
