Hi

out RAP website (www.gebrauchtteile.ch) gets slower over time indicating
memory leaks.

we do have a lot of changing images and as images can not be disposed() in
RAP i fear that memory finally gets exhausted.
Questions:
is there a internal mechanism that disposes images from time to time?
if not: what can we do to dispose() old images that are no longer used.

Thanks
Andrej

Andrej,

I assume that you refer to the server side which slower over time.
Which version of RAP are you using?

Images in RAP do not hold the actual image data but only a string
that denotes the location of the image file. Hence this is not what
exhausts the memory.

Best thing would probably be to use a profiler to track down the
problem.

Cheers,
Rüdiger

Hi Rüdiger,


can you recommend a special Java Profiler? which one do you use? i'd like to do some memory analysing on my RAP app, too.

thanks!

Hi Rüdiger

yes, i refer to the server side.
i use 1.1.1 SR-1. 1.2 is not possible as IE 6 is not supported.

could you recommend a profiler?

Thanks for the insights about how RAP is handling images.
Andrej

Andrej,

we mostly use YourKit (http://www.yourkit.com) that offers CPU and
memory profiling. If only a memory analyzer is needed, the Eclipse
MAT (http://www.eclipse.org/mat) is highly recommendable.
