RE: Slow instantiation of the Service class in client

Jason,

 

Just as Tony said, I tested your class in stand alone environment (dos prompt). It took a few second. I think most of the time was for waiting for time out as the service was not deployed at all. That means your client was ok in my win 2000 environment.

Brian,

 

Your test shows that I might have an issue with AXIS running on AIX.  The 8 seconds is the time it took for "Service  sv = new Service();" alone.  The time to send to the server & back is another 4 seconds.    I also ran my client without the service installed and still 8 seconds to create the Service object.   Sounds like I am having the same issue Tony had.   Instantiating the Call object is very fast but not so for Service.  Though unlike Tony's, my client is a standalone client.

I am a newbie in Axis. But I am also working on message style service.

I tested your program (without service installed) in window 2000 environment but the response was much quicker than 8 seconds. That may mean that the slowness is from your service, not the client. If you can share your service class code and wsdd file, I am willing to test it here.

Subject: Slow instantiation of the Service class in client

I am developing a test message-style AXIS client & server and notice that the client takes about 8 seconds for the client to instantiate the Service class on an IBM RS6000 AIX4.3 machine.  Is this quite normal or am I doing something wrong?  I used the provided sample code for message-style clients to create mine.  Below is the code.  Appreciate any insight in this.
