Urgent: Specifying scope in Axis2c
Hello everyone,
I have run in to an issue which I can't seem to figure out. In my init
method in the service skeleton I call the initialization routine of one of
the libraries that my web service uses. I notice in my logs that the library
initialization function is being called 8 times. This corresponds to the
number of apache processes that are running.
This is causing a lot of issues because I was under the impression that my
web service init function is called only once when the first request comes
in. My library sets up some resources which I want to share among all
processes. Can this be done?
In Axis2/Java there is a way to specify scope for the webservice (request,
session, application) in the services.xml file? can something similar be
done in Axis2/c? I took a look at the axis2c code and saw that there is an
enum called axis2_scope defined. Is it used for the same purpose as in
Axis2/Java?
Thanks for any help.
Subra

I have looked into this and proposed a solution to this on dev list.
However, as of now, I find it difficult to find time to attend to
this. I have to check if any other developer is attending this.
I cannot gaurentee if the proposed solution would work, as we have to
implemnt and see it in action to verify that it works. Given the risk,
I would propose that you look in to a database driven solution for the
time being until this is solved as I recommended earlier. As I
mentioned, Savan module had done something similar, so that you can
get an idea form that to solve this temporarily.
Thanks,
Samisa...

Hello Samisa,
Do you have any updates on this issue? Do you have an approximate time frame
when this issue would be fixed in the framework? Is this feature under
development?
This capability is very important for the application I am working on. If it
wont't be fixed in the framework anytime soon, I will have to come up with a
fix in my code.
Your help is much appreciated.

Nop, if you do that, I think you will get the same problem again.
I think you may have to use a database to do that. Savan module, the
WS-Eventing module, came across such a problem and used sqlite.
Can someone please explain how it was done in Savan?
In the mean time, the matter is discussed on dev list, and would have a
solution for this.

thanks samisa.

This is a problem yet to be solved in Axis2/C. See
http://damithakumarage.wordpress.com/2007/09/23/an-axis2-c-design-issue/.
This is a pending issue that needs to be fixed.
The workaround for the time being would be to use some persistent
storage to keep a flag and call the init routine based on the flag value.
