Ok I see. Is it in the Axis C++ roadmap to implement such feature ? It is currently well implemented by Axis Java, with this famous scope (application/session/request) parameter defined in the deploy.wsdd file... It works very well, and it keeps all the web service objects up during all the application life (when setting in application scope)
Thanks

Now you're talking about maintaining a session.
There is now way to do this "for-free". You could do it by setting cookies in the server-code. These cookies could be used to retrieve state from a db next call.
Cookies are supported, at some level, in the client but not the server - to my knowledge. (they are just transport properties) You might have to add some minimal logic into the server-code to do it.

Ok, so how can I retrieve previously loaded object of my library ? For the moment, when I call initService(), I initialize a business object. If I call my second web service method notifyDictionary() in the same process (the main of my client call this 2 methods), it works (like a session scope). Now if call only initService(), then stop my client, then call notifyDictionary() in a different client, it fails, because the business object has been destroyed.
How can I work around this ? Isn't it the feature "application scope" must provide ? Because the only thing I see, is that every server side objects are destroyed when the client is destroyed.

The dlopen subroutine loads the module specified by FilePath into the executing process's address space. Dependents of the module are automatically loaded as well. If the module is already loaded, i t is not loaded again, but a new, unique value will be returned by the dlopen subroutine.

First call to the method initService() is in log-1.txt, the second call (exactly the same, some seconds later) is in log-2.txt.
I tried with <parameter name="scope" value="application"> of server.wsdd file in some other tests, it didn't change anything.
Thanks

The logs are clear : it does a loadlib each time a method is called
2006/3/24, John Hawkins <[EMAIL PROTECTED] >:
I've not got time to look into this problem but it should not load the libs but it might be creating new instances of the objects. Can you confirm which?

Hi,
Could you confirm that it is a normal behavior that axis engine load libs each time a method is called on ? Or is it a mistake in my configuration ?
Thanks
2006/3/23, Antoine Galataud < [EMAIL PROTECTED] >:
Yes that's it.
2006/3/23, John Hawkins < [EMAIL PROTECTED]>:
OK,
so let me repeat it back to you so we're clear.
You tested and found that the library is loaded and unloaded on every method call?

No, I didn't test it yet. But I realized, reading again Adrian mail and looking at wrapper class that it can't be my solution (or just a part of). What I'm saying is that the wrapper class is contained in the web service library, and is used to initialize and stop the web service with init and fini methods. But this doesn't resolve my problem: I want the library loaded and run until server shuts down. So what I need is the scope parameter of server.wsdd file correctly handled (I tested that it doesn't work), so the library is loaded at first request and stays up.
2006/3/23, John Hawkins < [EMAIL PROTECTED]>:
Sorry, I'm not clear what you are saying - are you saying that you have tested this and the library is loaded each time the service is requested?

Hi,
this a very great manner to initialize my business objects before
getting a request, but does this help to have the web service library
loaded once and not unloaded when method returns ?
I mean, for the moment I can't call a method without having Axis
loading the web service library (at each call). I need it to load at
first time, then be up until server (apache) shuts down.
What you are saying is that library is loaded at first invocation and
unloaded when server shuts down. But in my case, library is loaded
each time the service is requested !
Thanks
