New Axis2c user - Axis2c API returning NULL
Hi,
I am a new user of Axis2c and I am stuck because of the following:
I have WSDL generated C stubs and using axis2c-1.7.0 to deploy web service
based on them. I am on server side.
Below is my code snippets that I tried to get HTTP header and it is
returning NULL. Actually I am trying to get Cookie information from header.
I could see the headers with Cookie information when I did a packet
capture using wireshark, where Axis2c API is returning NULL for the same.
Please let me know if there is anything wrong with the following code.
1) First method
axutil_property_t* property = NULL;
axis2_char_t* prop_val = NULL;
property = axis2_msg_ctx_get_property(msg_ctx, env,
AXIS2_TRANSPORT_HEADERS); // <--- this is returning NULL
if (property == NULL)
{
printf("property is NULL\n\n");
}
else
{
prop_val = (axis2_char_t*)axutil_property_get_value(property, env);
if (prop_val == NULL)
{
printf(" prop_val is NULL\n\n");
}
else
{
printf("prop_val: %s\n\n", prop_val);
}
}
2) Second Method
axutil_hash_t* header = NULL;
header = axis2_msg_ctx_get_transport_headers(msg_ctx, env); // <---
This is returning NULL
if (header)
{
axis2_http_header_t* test = NULL;
test = (axis2_http_header_t*) axutil_hash_get(header,
AXIS2_HTTP_HEADER_COOKIE, AXIS2_HASH_KEY_STRING);
if (test)
{
axis2_char_t* val = NULL;
val = axis2_http_header_get_value(test, env);
if (val)
{
printf (" axis2_http_header_get_value, val: %s\n\n", val);
}
else
{
printf("axis2_http_header_get_value returned NULL\n\n");
}
}
else
{
printf("axutil_hash_get returned NULL\n\n");
}
}
else
{
printf("axis2_msg_ctx_get_transport_headers returned NULL\n\n");
}
Any help is appreciated.
Thanks,
Pavani

By the way, synchronous examples worked for me (tested with online
webservices). I think that now I have working a synchronous client wrapped
in c++ with cilent api. If you need some extra examples tell me.

Re: New Axis2c user - Axis2c API returning NULL
Posted by Pavani J <jp...@gmail.com>.
Hi,
I forgot to mention that I am using simple axis2 HTTP server,
axis2_http_server on linux.
Below is from client to server:
POST /axis2/services/MyService8.0 HTTP/1.1
Cookie: MYSESSIONID=92f1e42d-bef3-4726-9b31-a5335ec123f8
Content-Type: application/soap+xml; charset=utf-8;
action="urn:getNumberOfEntries"
Host: 10.112.8.137:9090
Content-Length: 538
Expect: 100-continue
Accept-Encoding: gzip, deflate
I am interested in Cookie in the header.
Any help is appreciated.
Thanks,
Pavani

Re: New Axis2c user - Axis2c API returning NULL
Posted by Pavani J <jp...@gmail.com>.
Hi,
I went through samples/server/session.
Do I need to
1. have/create mysql database table for session-table
2. build apache module with mod-dbd enabled
for message context, msg_ctx to return Cookie information?
Or it is there for sample code to work?
Client is setting HTTP headers properly, I can see Cookie information on
wireshark.
Any help is appreciated.
Thanks,
Pavani

AW: New Axis2c user - Axis2c API returning NULL
Posted by Stadelmann Josef <jo...@axa-winterthur.ch>.
I have a question:
Are the samples delivered with your axis2C kit running?
There are all kind of samples, simple and more complex ones.
If you work / debugging through this examples, you learn a lot.
Once an example is running, enhance it with your code below: i.e.
call to axis2_msg_ctx_get_property
But make sure, that at the client side, the client has in fact feed a
property into the message context.
If the client does not pass a property into the message context for
transport to the server, NULL at the
server side is normal. Or what else would you expect from the server in
this case?
