Re: [Axis2] Building samples in MS Visual Studio]
I tried this on Windows. It looks to me the kind of error that you are
getting is given when the DLL is corrupted or it does not implement
the expected format.
Please double check the DLL.
Have you used the same code as the sample or did you modify it? If you
modified, please send the code.
Thanks,
Samisa...

Subject: Re: [Axis2] Building samples in MS Visual Studio
Hi Sahan,
Thanks for the reply. I've been putting my built dll into a directory
called $AXIS2_HOME/services/EchoWebService with the dll name as
EchoWebService.dll and the services.xml file containing the following:
<service name="EchoWebService">
<parameter name="ServiceClass" locked="xsd:false">EchoWebService</parameter>
<description>
This is a testing service , to test the system is working or not
</description>
<operation name="echoString">
<!--messageReceiver class="axis2_receivers" /-->
<parameter name="wsamapping" >
http://ws.apache.org/axis2/c/samples/echoString</parameter>
</operation>
</service>
I removed the original echo sample (in case there was some clash
happening) and the code itself is exactly the same as the sample, but
I'm still getting this error. I attach the full axis2.log trace file.
Thanks
Andrew

Hi,
Yes. Either the dll is corrupt or the dll does not contain the functions
required by the axis2 core to load the dll in. The required functions are :
AXIS2_EXPORT int
axis2_get_instance(axis2_svc_skeleton_t **inst,
axis2_env_t **env)
and
AXIS2_EXPORT int
axis2_remove_instance(axis2_svc_skeleton_t *inst,
axis2_env_t **env)
This is contained in the echo_skeleton.c file in the
"samples/server/echo" folder. Have you included this file in your dll
project ?

Re: [Axis2] Building samples in MS Visual Studio]
Posted by Andrew Borley <aj...@gmail.com>.
Hi Samisa,
I've managed to get it running! My issue was that in MSVC++ the default
build setting is to "Compile as C++ Code".
Changing to "Compile as C code" makes it work.
When I started looking at Axis2C I used the defaults ("Compile as C++ Code")
and got some conversion errors:
d:\cpp\EchoWebService\echo_skeleton.c(53) : error C2440: '=' : cannot
convert from 'void *' to 'axis2_svc_skeleton_t *'
Conversion from 'void*' to pointer to non-'void' requires an
explicit cast
d:\cpp\EchoWebService\echo_skeleton.c(56) : error C2440: '=' : cannot
convert from 'void *' to 'axis2_svc_skeleton_ops_t *'
Conversion from 'void*' to pointer to non-'void' requires an
explicit cast
So, (late on Friday afternoon) I took the advice and added some explicit
casting to the failing lines. This makes the build happy and I have a nice
dll (built as C++) that doesn't work.
When you asked me if the code was the same as the sample I checked it over
and discovered these extra casts. Removing them makes the "Compile as C++"
fail again, but discovering and changing to the "Compile as C" setting and
it's all working fine.
So the moral is: check what the default settings are!
Thanks for the help
Andrew
