This error usually happens when op_client unable to locate the
transport in/out descriptors (as you mentioned in the later in this
mail). According to my knowledge That happens due to several reasons.
++> When and where in code are this descriptors setup when the client starts?
++> I am glad to set a debugging breakpoint in the OpenVMS debugger by using
++> DBG> set module "xyz_modul"
++> DBG> set break xyz_modul\abc_function
++> DBG> go
and see how this routin behaves when it is used to setup the transport descriptors
++> I am nearly shure there is a problem with the transport descriptor setup in \
OpenVMS, ++> so that the infer of transport which after all referes to transport \
descriptor does not succeed

information they use to get setup corectly ++> then I will do the same for OpenVMS
1. axis2.xml has wrong transport sender/receiver information
++> so what is the correct sender/receiver information?
2. Axis2/C engine unable to locate libaxis2_http_sender.so or
libaxis2_http_receiver.so.
++> as we are in OpenVMS there is no such thing as a libaxis2_http_sender.so :-) BUT \

3.When there is unloadable (corrupted) library.

++> loade dynamically when regarding transport issues? I can set a break point at the \
axutil_class_loader() ++> and see what is requested for a load. Then verify that each \
path points to a wanted DLL / sharable image.
BTW, what axis2/c version are you using? as per log messages it should
be prior to the Axis2/C 1.1.0.

AFAIK, AXIS2C_HOME is not important , but repo_path is
essential. (AXIS2C_HOME use to make the repo_path). Repo path is use
to find axis2.xml. Details in axis2.xml use to build axis2
configuration.
