RE: Slow instantiation of the Service class in client

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.

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.
