Re: Redirecting Web Services

[Subra A Narayanan]

Brian,

Basically this is what is happening here:

1. YourClient => Initial Request =>1st Server
2. 1st Server => 301 Response => YourClient
3. YouClient is supposed to interpret the 301 response and resend the
request to the 2nd Server. But since ur client is written in Axis2c which
doesn't support redirection, ur client doesn't know what to do with the
response and doesn't take any further action.


Your browser on the other hand, knows how to interpret the 301 response and
goes after the new location (2nd Server).


So the bottom line is, ur server is behaving correctly. Try writing a client
in some other language like c# or java and I am sure this issue will go
away.

Incorrect SoapFault format

Hello folks,

Rampart v1.2 is not generating soap faults correctly. The response below is

node does not belong here.  is part of soap1.2 fault not soap1.1
fault.

rampart libs being copied incorrectly

[Subra A Narayanan]

Hey guys,

I downloaded axis2c 1.4 and rampart 1.2 and built them. when I did an ls -l
of the axis2/c lib folder, i saw this

bash-3.00$ ls -l axis2c/lib/libmod_rampart.*
-rwxr-xr-x  1 subra user1551 Jun  4 18:34 /nfs/home/subra/axis2c/lib/
libmod_rampart.la
-rwxr-xr-x  1 subra user 6485794 Jun  4 18:34
/nfs/home/subra/axis2c/lib/libmod_rampart.so
-rwxr-xr-x  1 subra user 6485794 Jun  4 18:34

-rwxr-xr-x  1 subra user 6485794 Jun  4 18:34
/nfs/home/subra/axis2c/lib/libmod_rampart.so.0.0.0

as you can see the symbolic links are missing here. 'libmod_rampart.so' and
'libmod_rampart.so.0' are not linked to 'libmod_rampart.so.0.0.0'

but in the axis2c/modules/rampart folder, they are linked correctly. My
question is:

1. why are these libraries even present in the axis2c/lib folder. as far as
i remember, this was not happening in earlier versions of rampart.
2. will they cause any problem/conflict?

Reload mod_axis2

[Subra A Narayanan]

Hello all,

I was wondering if there was a way to reload the apache axis2 module (so
that it picks up config file changes like loglevel) without having to
restart apache? The reason I ask this is I have other modules loaded in to
apache and I want those modules to continue serving incoming requests when
axis2 module is unloaded and reloaded.

Thanks!

Module conflict

[Subra A Narayanan]

Hello folks,

I am running in to another problem and was wondering if I could get some
help from you guys.

Another developer in my team had to add the following lines to httpd config
file. These lines are in a separate .conf file which is placed in the
/etc/httpd/conf.d/ directory and gets included in the main httpd.conf file.

DocumentRoot /srv/www/html/WebUI/public/

Options ExecCGI FollowSymLinks
AddHandler cgi-script .cgi
AllowOverride all
Order allow,deny
Allow from all


We realized that once this is added, we are unable to access our axis2 soap
webservices. We are not even able to bring up the page that lists all the
services and the operations. Looks like that the axis2 httpd module isn't
loading properly.

I did some research and I think it might have something to do with the per
server config and per directory config structures in the axis2 apache
module. Do we have to merge the directory config structures? I am kind of
new to writing apache modules so pls excuse my ignorance if I am wrong. I
will continue to investigate this issue as one of my own apache module is
also not working because of this.

In the meantime, if you guys have any idea please let me know.


Thanks,
Subra

I have downloaded ver 1.3 and would like to try my code with this version.
but before I begin I just wanted to make sure that I am doing evrything
correctly.

What do you mean when you ask me to checkout from a branch? Do you want me
to checkout just the build.sh file? isn't the build.sh file from axis2 1.1good?

Here are my CFLAGS and LD_FLAGS value. Here 'myclient' is the external
library I have been telling you about.
CFLAGS = -fPIC -static-libgcc -shared -z initfirst
LD_FLAGS = -L /deps/axis2c/lib -L /mylib/ -l axutil -l axis2_engine -l dl -l
pthread -l myclient

Yes the library is in a locatable path. It works just fine with Axis2 1.1.
It gives me problem only with Axis2 1.2

Also I make couple of different calls to myclient library. Looks like only
when I call a function that uses multiple threads does my code hand.


>

> >source trees

I used the build.sh file that came with the distribution for compiling axis.
Since there was no build.sh file in the axis1.2 source tar, I copied the one
from axis1.1

I am running both axis1.1 and 1.2 on the same version of httpd. i have a
vmware image that i use for my testing. so the run env is exactly the same.

Re: Axis2/C 1.2 breaks my webservice

[Subra A Narayanan]

Hello folks,

Here are my findings:

A little more background first. The external library that my webservice
calls is a multithreaded library and uses semaphores for inter-thread
communication.  When I was in the process of debugging this problem, I
started httpd with the -X option (to limit httpd to a single process). When
I did this my webservice started working just fine. I stopped httpd and
started it normally and again my service hung up a particular call to my
external library.

Again the same code works just fine with Axis1.2

My question to you guys is:

-> Has something changed between Axis1.1 and Axis1.2 that would cause this
behavior?
-> Is this information enough or do you still want gdb trace information?

Thanks for all the help.

Re: Axis2/C 1.2 breaks my webservice

[Subra A Narayanan]

Hello folks,

I also recompiled my code against Axis2 1.2 before trying to run. Even then
I am having trouble running it. Its not like the webservice code doesn't
comeup at all. I can see the request coming in, the input params being
processed and then it hangs when trying to call an external library.

I am running some other tests to see if I can get any further. I will report
my findings soon. In the meantime, if you guys can think of ways to track
down the problem, please let me know.

Axis2/C 1.2 breaks my webservice

[Subra A Narayanan]

Hello folks,

I ran in to a curious problem and was wondering if anyone else has seen it
too. My webservice code works just fine with Axis2/C 1.1 . But when I
checked out version1.2 source code from here =>
http://svn.apache.org/repos/asf/webservices/axis2/tags/c/1.2.0-rc2-4/ my
service stops working. I make a call to an external library(.so file) from
my webservice code and I see that my code hangs when I call this external
library.

The same code works just fine with Axis2 ver 1.1. Any idea as to what might
be wrong?

Thanks,
Subra

As far as I know Axis2C doesn't generate the wsdl automatically for you. I

Rampart question

[Subra A Narayanan]

Hello folks,

1. How is role based authorization handled in Rampart? The Username and
password (basic or digest) just provide a way to authenticate the user, but
not authorize.

2. Is there anyway in Rampart/Axis2C to pass down the username from the
UsernameToken to the webservice code (after the username and password have
been authenticated) so that the webservice can then use the username to
determine if a user is authorized to access a particular resource or not.

Thanks for the help!

Re: HTTP Authentication (Basic and Digest)

[Subra A Narayanan]

One clarification

When we talk about support for Basic/Digest HTTP Authentication in Axis2/C,
we are talking about only the client side right? There is no problem on the
server side since this is taken care by the apache httpd server, correct?

So if my service is written in axis2/c with Digest Authentication enabled in
apache, and if I use Microsoft .Net client, I should be fine, right?

HTTP Authentication (Basic and Digest)

[Subra A Narayanan]

Hello folks,

I have 2 questions that I hope someone can answer

1. Is there any plan for supporting HTTP Digest Authentication anytime soon
in Axis2/C?

2. Are these still issues with Basic Authentication in Axis2/C? If yes, will
they be fixed in release 1.2?

Re: mod_axis2 could not be loaded

[Subra A Narayanan]

Did you build the axis2 apache module according to these instructions:

http://ws.apache.org/axis2/c/docs/axis2c_manual.html#mod_axis2

axis2_http_server will work without the module but to deploy axis2 under
apache, you would need the module.

session cookies

[Subra A Narayanan]

Hello folks,

I have a webservice that requires that should be accessible only by
authenticated users. right now, the way it works is, each and every request
has to be authenticated. i was wondering, if there is a way in axis2/c to
generate a session cookie or id which would be valid for a given period of
time. the webservice would set this cookie after the first request comes in
and is successfully authenticated but each subsequent request would just
pass this cookie and there will be no need for authenticating every incoming
request.

does this make sense? is it doable in axis2c?

Re: Axis2/C Memory Leaks

[Subra A Narayanan]

So there are still some known memory leak issues in axis2/c? I have
been doing some testing to look for memory leaks and I do see that
memory is being lost. I am using apache and _not_ the simple axis
server.

do we know when axis 1.2 is scheduled to be released? we are getting
pretty close to our launch date, thats why I am concerned.

the memory leaks that you have found, are they significant?

ur input is much appreciated.

Re: [Axis2] SSL and certificate support

[Subra A Narayanan]

Hey Dumindu,

Just want to make sure I understand this correctly. So if I just want
to run my axis2 webserices in SSL mode, I dont need rampart. I can
just use apache for that, right? But when I was reading rampart
documentation, it talks about soap body encryption using SSL certs.
How is that different from using apache for SSL?

My second question is, lets assume I want to use client authentication
for my webservice. I have to set the following 2 variables in the
httpd.conf file

SSLVerifyClient require
SSLVerifyDepth 1

I understand that this will force the client to send a cert with every
request. But after receives the client cert, what does it do with it?
does it check against a list of certs thats allowed to access the
service? Is this feature built-in to axis2 or do we hv to implement it
ourselves?


Thanks,
Subra

Hi Greg,

Yes, Axis2/C supports both ssl server authentication and client
authentication. Please refer to the axis2c manual [1].

I would suggest you use axis2 1.0.0 RC3 [2] or the latest svn head,
since ssl transport has been updated since 0.96 release. In this case
you will have to refer to the documentation from the trunk [3].

Note that ssl transport is not a feature of rampart, but of Axis2/C itself.

Dumindu.

Re: [Axis] Re: sync up modules error handling with new error blocks specified.

[Subra A Narayanan]

Hello,

Could you guys please provide some more information about this.

Should we just do a svn update to get the new code?

A brief tutorial as to what should be done to use this user error
block would be good.

There is some sample code in this thread here =>
http://marc.info/?l=axis-c-user&m=119106211228220&w=2
which I am currently using in my webservice. What changes will I need
to make to make use of the new custom error functionality.

Thanks in advance.

Re: custom error message with c server

[Subra A Narayanan]

Michael,

If you are setting the soap fault correctly on your server side, your
java client when it receives the soap response back with the soap
fault in it, should automatically throw an exception. You can then
retrieve the exception using ex.message.

May be someone from the Axis2 team can correct me if I am wrong.

Do you have any updates on this issue? Do you have an approximate time frame

This capability is very important for the application I am working on. If it

Re: axis simple http server versus apache

[Subra A Narayanan]

Hey Michael,

I think the reason you are getting this error is because apache is not able
to locate and load one of you libraries. Try this:

copy all ur shared libraries in to the /usr/lib (or /usr/lib64 ) folder and
try ur test with apache again. If that solves ur problem, you may need to
modify ur ld.so.conf file to add the location of ur library files to tell
apache where to look for the library files that it needs.

8.ns = axiom_namespace_create(env, NAMESPACE_URI, NAMESPACE_PREFIX);

11.  axiom_element_set_text(fileName_om_ele, env, fileName,
fileName_om_node);

12. return resp_om_node;
}

The node returned from the above function is returned as it is to the client
without any further modification.

My question is, since I am explicitly creating the resp_om_ele and
fileName_om_ele, I should be freeing them too, right? But where exactly do I
do that? Can I do that right after line 11? But then what happens to the
resp_om_node?

Or should I not be worrying about freeing the two elements?

Please advise.

Re: Memory Issues in Sample Server Code

[Subra A Narayanan]

Dinesh/Samisa,

I am using Apache 2.0.59 with axis 1.1. Do you think upgrading to
apache 2.2might solve some of these issues? Are you guys aware of any
memory
management issues with apache 2.0?

Samisa, a quick question for you. In you email, you mentioned that calling
free is not going to free up memory from the apache pool. Does that mean
that I dont have to call AXIS2_FREE for any memory that I explicitly
allocated using AXIS2_MALLOC? Then why do we need the free function? Please
clarify.

Thank you,
Subra

Re: Memory Issues in Sample Server Code

[Subra A Narayanan]

Hello David,

Were you able to run the test again after adding some of the free()
statements back in? Did it improve the performance? I am seeing a similar
issue where the memory footprint of the apache process keeps increasing
until a point when the server becomes very unresponsive and my client starts
getting timeouts.

After a while the root apache process spawns some new processes and the
server starts responding again. But the earlier apache processes never free
up their memory. Their memory usage reaches about 60mb and kind of stays
there.

I am using Axis 1.1 with apache 2.0.59.

May be someone from the Apache team can shed some more light.


Thanks,
Subra

Re: issue 731 - please have a look

[Subra A Narayanan]

Hello,

So what is the proposed solution to this problem? Is the code going to be
changed so that apr_base64_decode_len() always returns the correct length or
should developers use [axutil/apr]_base64_decode() to get the exact length?

I use the apr_base64_decode_len() function to allocate memory for attachment
recvd via the webservice and that introduces garbage characters in the end
as the len function always returns a value greates than the actual length.

Bug in axis2c xml parsing?

[Subra A Narayanan]

Hello folks,

I use the following code to parse an incoming ws request. I am posting only
snippets of the code for sake of brevity

**CODE
BEGIN***
axutil_qname_t *Qname = axutil_qname_create(env, "Price",
MY_NAMESPACE_URI, MY_NAMESPACE_PREFIX);
axiom_node_t *myNode = NULL;
axiom_element_t *myElement = NULL;
myElement = axiom_element_get_first_child_with_qname(rootElement, env,
Qname, rootNode, &myNode);

if (myNode)
{
...
...
...
return AXIS2_SUCCESS;
}
else
{
AXIS2_LOG_DEBUG(env->log, AXIS2_LOG_SI, "Error!!");
return AXIS2_FAILURE;
}

**CODE
END**

If I have a node like this, it just works fine (here 'MyOperation' is the
root node from above)


   250



but if I have a node like this


   


the control goes in to the else condition and it returns AXIS2_FAILURE

I would think this shouldn't be happening since we do have a 'Price' node
although it is empty.

Is this by design or have I found a bug?


Thanks,
Subra

Urgent: Specifying scope in Axis2c

[Subra A Narayanan]

Hello everyone,

I have run in to an issue which I can't seem to figure out. In my init
method in the service skeleton I call the initialization routine of one of
the libraries that my web service uses. I notice in my logs that the library
initialization function is being called 8 times. This corresponds to the
number of apache processes that are running.

This is causing a lot of issues because I was under the impression that my
web service init function is called only once when the first request comes
in. My library sets up some resources which I want to share among all
processes. Can this be done?

In Axis2/Java there is a way to specify scope for the webservice (request,
session, application) in the services.xml file? can something similar be
done in Axis2/c? I took a look at the axis2c code and saw that there is an
enum called axis2_scope defined. Is it used for the same purpose as in
Axis2/Java?

Thanks for any help.

Re: Help needed on building custom soap fault in axis2c

[Subra A Narayanan]

Hi Dimuthu,

I am using the solution you suggested in your last mail. That solution is
perfect for my application. But I have some concerns. I saw this line in
your code

#define MYSERVICE_ERROR_CODES_START (AXIS2_ERROR_LAST + 2000)


Will this cause any problems in the future? What if the value of
AXIS2_ERROR_LAST changes? Or what if some other axis2 component (like
sandesha or neethi or something else) uses error codes in the same range?
Will I be forced to change my code because of the above scenarios?

Any help is greatly appreciated.

axis2-deploy-directory/services/userdata folder. libuserdata.so uses another
library called libtestws.so. This is file that is not being loaded. I placed
this file in the same directory as libuserdata.so but even that didn't help.

But when I placed the file in /usr/lib folder, apache found it and loaded it
successfully.

But is there any way to tell apache to look in some other folder for the
file. I dont want to add all my library files to /usr/lib file but want
apache to look in /my/library/files/folder. Can this be done?

Thanks,
Subra

Unable to locate/load library

[Subra A Narayanan]

Hello folks,

My webservice calls a c library but is unable to load it as it can't locate
it. I put some debugging code in the framework code and this is what I see
in the axis2 log.

[Mon Sep 17 16:53:41 2007] [error] raw_xml_in_out_msg_recv.c(110) Impl
object for service 'object' not set in message receiver. 100 :: Failed in
creating DLL
[Mon Sep 17 16:53:41 2007] [debug] raw_xml_in_out_msg_recv.c(115)
create_funct failed 'libtestws.so: cannot open shared object file: No such
file or directory' :
[Mon Sep 17 16:53:41 2007] [debug] engine.c(296) Axis2 engine receive
completed!


I have set the LD_LIBRARY_PATH and the file is in the path. Is there
something else that I am missing?

Is there an apache start up script file or something where I can specify
where to look for library files? My web service builds perfectly fine with
the correct LD_FLAGS options. The error happens when I try to invoke the
service.

Thanks,
Subra

Changing the web service end point

[Subra A Narayanan]

Hello everyone,

Endpoint for Web services written using Axis2c are generally of the format

=> http://www.foo.com/axis2c/services/servicename


By modifying the httpd.conf (or apache2.conf) file, I was able to change the
above to

=> http://www.foo.com/subra/services/servicename


Now I would like to get rid of the word "services" from the uri. How do I do
that. Is that even possible?


Thanks for any help!

Re: REST with Axis2/C

[Subra A Narayanan]

Good Morning Samisa,

Could you pls elaborate a little bit more on ur statement "The problem you
would have to solve in
this case would be, how to handle the resources requested to a service."

I am not sure I understand that correctly.

Also can you point me to code in Axis2/C framework where I could begin
looking to get ideas for my module (this is the first time I will be writing
one). Also I will start looking into libcurl. Is threading a major issue
that needs to be dealt with while writing modules?


Thanks in advance!

Hi Dinesh,

Do you if it will be done in time for release 1.1? It would be a great help
as right now there is no way of sending meaningful error messages to client.

Thanks,

Re: REST with Axis2/C

[Subra A Narayanan]

Hey Samisa,

First, I apologize for the delay in replying.

I feel, the reason REST has got so much attention lately is because of its
perceived simplicity. I feel supporting REST by converting REST requests in
to SOAP requests behind the scenes may not be a good idea. One major problem
that I can see with that approach is how do we handle REST requests with
attachments?

Can we have the ability in Axis2 to define 2 service endpoints? Lets say
something like

http://www.foo.com/axis2c/ - for SOAP (which is how axis2c works today)

http://www.foo.com/axis2c/REST - for REST


Then in the axis2_apache2_worker_process_request function in the
apache2_worker.c file, depending on the end point either axis2 continues to
do what it is doing today or hands over the request (request_rec struct) to
the user written code who can process it in anyway and return a response.
This will give so much flexibility to for REST development. The ws creator
can then take care of issues like attachments, multiple parametrs for the
operations etc at the same time making use of the rich library that axis2
provides. And also the user (service creator) can let axis2 worry abt
threading and memory management issues.

Such a feature would be a great help for developers like us who want to
provide a full fledged REST support for our services. Thoughts?

Re: HTTP return codes

[Subra A Narayanan]

I apologize for the delay in replying.

My question was somewhat related to the my other question about REST support
in Axis2c. I have seen that a lot of webservices with REST support return
standard HTTP return codes like the following as a response

501- NOT IMPLEMENTED

*400 - Bad Request*
The syntax of the request was not understood by the server.

*401 - Not Authorised*
The request needs user authentication

Thats why I wanted to find out if something similar can be done in Axis2c as
well.

HTTP return codes

[Subra A Narayanan]

Hello everyone,

Is there any way to return standard HTTP return codes to the clients from a
Axis2/C web service. For e.g. HTTP 404, HTTP 201, etc etc.

Subra

Re: REST with Axis2/C

[Subra A Narayanan]

Hey Samisa,

The way Axis2/C supports REST is not fully REST compliant (I am sorry to use
the word compliant since REST is not really a standard). REST says
everything is a resource and URI represent resources. So the URIs should
have nouns in them rather than verbs. For e.g. in the Amazon S3 webservice
example, the uri just had the object name but what action needs to be taken
on the object is decided by the HTTP method (GET retrieves the object,
DELETE removes it and PUT stores the object. The URI is the same in all the
3 cases)

Here are my thoughts:

I have been going through the Axis2/c framework code and I think I have a
fair (although not complete) understanding of how REST works in Axis2. If we
can have a way to let the developers of the webservice write their own
implementaion of how to handle REST request, that will be great.

Something like an interface that the developers have to implement so as to
receive RESt requests. Once the request is received, it is up to the
developers to construct the corresponding SOAP message by looking at the URL
and the HTTP method and give it back to the framework which inturn forwards
the SOAP envelop to the web service implementation.

They say a picture is worth a thousand words - I will try to summarize this
whole thing as a diagram first thing tomorrow morning and send it to you
guys.

I would like to emphasize that the above is my understanding of how REST
works and I admit it may be flawed. So feel free to correct me lets discuss
what is the best way to implement REST in Axis2.


Thanks for the help!

Trouble using external library in Axis2/C

[Subra A Narayanan]

Hello folks,

I want to use an external library in my Axis2/C webservice. I library is a
shared library (.so file). In my webservice's init method, I call the
initialization function of my library and in the free method I my library's
free function to free up resources.

Then I compile my service and place .so file in the
axis2c/services/myservice folder. When I try accessing my webservice i get
the following error in my axis2.log file

Please see the error generated in the raw_xml_in_out_msg_recv.c(109) file. Why

If yes, how should I solve this problem?

Thanks for any help!

Re: REST with Axis2/C

[Subra A Narayanan]

Samisa,

I have been looking at the code that you pointed me to and trying to figure
out how REST works. Right now, the method name needs to be in the URL for
REST to work. To make Axis2/C more RESTful, we would need a way to map HTTP
methods and keywords in the URI to map to webservice method names. I will
take amazon s3  service to explain what I mean. Look at the following 2
requests:

#1 get object request

GET /[bucket-name]/[key-name] HTTP/1.0
Date: Wed, 08 Mar 2006 04:06:18 GMT
Authorization: AWS [aws-access-key-id]:[header-signature]
Host: s3.amazonaws.com


#2 delete object request

DELETE /[bucket-name]/[key-name] HTTP/1.0
Date: Wed, 08 Mar 2006 04:06:19 GMT
Authorization: AWS [aws-access-key-id]:[header-signature]
Host: s3.amazonaws.com


The above 2 requests look exactly the same except for their HTTP methods:
GET vs DELETE. In Axis2/C I think we would need a way to may HTTP method
name/key word in URI to be mapped to a webservice operation name so that the
soap request can be formed accordingly.

Do you have suggestions as to how this can be done in a generic way?

Thanks,
Subra

REST with Axis2/C

[Subra A Narayanan]

Good morning folks!

This is more of a approach/design question rather than an Axis2/C question.

The project I am working on requires that I provide both SOAP and REST
interface to my webservice. With Axis2/C SOAP is no big deal. But REST is
something I am not too sure about. As it says in the API documentation
itself, Axis2/C is a SOAP toolkit and REST is not supported that well.

These 2 issues in particular
1) There is no support for PUT and DELETE
2) Also the way Axis2/C requires the operation name and the operation
parameters in the url, is a shift away from REST as there is no resource
representation.

So the solution looks like writing an Apache module (I have never written
one before) which receives the REST request, translates the request to a
SOAP request and then forwards it on to Axis2/c. But this is exactly what
Axis2/C is also doing.

I want to start looking in to improving REST support in Axis2/C. Is it
doable? Am I missing something very obvious which would prevent us from
implementing such support in Axis2? If not please let me know as to where I
should start looking in the Axis2 source.

If the above approach is not feasible, I will have to look at other ways of
supporting REST. One way would be to write my own apache module.

I would love to hear any comments/suggestions.


Thanks a lot for all the help!

Re: SOAP fault builder

[Subra A Narayanan]

Dinesh,

Thanks for your reply. I tried running the same servive with the
asix2_http_server and the client successfully receives a soap fault. No
problems there. So I think it is a bug with apache http server module. If
you guys concur, I will open a JIRA issue. It would be really nice to have
this problem fixed.

Having a way to return custom error codes/messages to client would be a big
plus? This way the client would know where exactly the error lies, on the
server side or in the request itself. Should I create a JIRA issue for this
too. If yes, under which category?

Thanks,
Subra

Re: SOAP fault builder

[Subra A Narayanan]

Hey Nandika,

Thanks for your reply. Looking at the
axis2_raw_xml_in_out_msg_recv_invoke_business_logic_sync function in
raw_xml_in_out_msg_recv.c was very helpful.

So I modified my code accordingly and I think I might have found a bug in
the framework. This is what I did

1. Set error status to AXIS2_FAILURE using AXIS2_ERROR_SET
2. Return NULL from my service
3. Implement myservice_on_fault function and create an axiom node which gets
added to the soap fault details node.

No when I try return a soap fault, the server sends a 500 Internal Server
error to the client. Chris Darroch created a JIRA issue late last year about
this bug here => https://issues.apache.org/jira/browse/AXIS2C-328 but I dont
think the bug has been fixed (pls correct me if I am wrong). I used TcpMon
to capture the response and this is what the client sees:

HTTP/1.1 500 Internal Server Error Date: Tue, 21 Aug 2007 17:39:55 GMT
Server: Apache/2.0.59 (rPath) Content-Length: 613 Connection: close
Content-Type: text/html; charset=iso-8859-1  

500 Internal Server Error

Internal Server Error
The server encountered an internal error or
misconfiguration and was unable to complete
your request.
Please contact the server administrator,
 [EMAIL PROTECTED] and inform them of the time the error occurred,
and anything you might have done that may have
caused the error.
More information about this error may be available
in the server error log.

Apache/2.0.59 (rPath) Server at 168.159.116.42 Port 80


I modified the axis2_raw_xml_in_out_msg_recv_invoke_business_logic_sync
function
to log the soap fault message to axis2.log file just before it returns and
see the correct soap fault message. So something happens after this point
which makes the apache http server send a 500 Internal server error to the
client.



My second question was, is there a way to return custom error numbers and
error message to the myservice_on_fault function so that the error
number/msg can be included in the soap fault. Right now only predefined
AXIS2 error message can be set using AXIS2_ERROR_SET. I understand that I
can modify axutil_error.h file but it says that the error codes are reserved
for modules. Is there any other better way of doing this?


Thank you folks!

Subra

Memory management in Axis2/C

[Subra A Narayanan]

Hello everyone,

I had some very basic questions about memory management in Axis2/C and hope
I can clarify my doubts with your help. I did go through the article on
memory management => http://wso2.org/library/237 but still have some
questions.

1. I am working on a new webservice for which I just copied the 'math'
service from the samples and have been just modifying it. In the 'add'
operation of the 'math' service, there are some calls to
axiom_element_get_text function which returns a const axis2_char_t* to
retrieve the parameters from the soap xml document. Who is responsible for
freeing up this memory? I assume since its const pointer and I didnt
explicitly allocate memory, it will be clened up by the framework. But when
does this happen? I looked at the math_free function in math_skeleton.c file
but it doesn't tell me much. Is this when the clean up happens?

 int AXIS2_CALL
math_free(axis2_svc_skeleton_t *svc_skeleton,
const axutil_env_t *env)
{
if (svc_skeleton)
{
AXIS2_FREE(env->allocator, svc_skeleton);
svc_skeleton = NULL;
}
return AXIS2_SUCCESS;
}



2. Is there any advantage in using the AXIS2_MALLOC over jus malloc? From my
understanding, AXIS2_MALLOC just hides the env specific implementation of
memory allocation. So if I am using 'C' either malloc or AXIS2_MALLOC are
one and the same. Am I correct? On a similar note, is there any advantage in
using axis2_char_t* over just char*?


I thank all of you for ur help and patience as I try to understand the Axis2
framework.

Using Axis2 functionality

[Subra A Narayanan]

Good morning folks,

Is it ok to use AXIS2_LOG_DEBUG (and other related logging functions) to log
errors/info/trace from my web service code to the axis2 log file? Or was the
logging functionality designed to be used only by the Axis2 framework? Any
downside of using the axis2 logging functionality? Its so convenient and
tempting to use. Please share your thoughts on this.

Thanks,
Subra

Re: SOAP fault builder

[Subra A Narayanan]

Hey Nandika,

So I tried your suggestion but I have a doubt. I am just modifying the
'math' webservice from the samples folder.

The 'add' operation returns a axiom_node_t * on success, which is nothing
but the soap message. But I want to return a soap fault from the
'add'operation if lets say one of the parameters was missing from the
request or
it was a decimal number. If I follow what you asked me to do, what do I
return from the add function? I have to return a axiom_node_t *? But from
your email I thought you meant that if I set the soap fault to the message
context, the soap fault will automatically be returned to the client. I dont
understand how do I stop further processing and return a soap fault to the
client.

So I did some further digging in to the axis code and found this function in
axiom_soap_envelope.h:

 AXIS2_EXTERN axiom_node_t* AXIS2_CALL
axiom_soap_envelope_get_base_node(axiom_soap_envelope_t *envelope,
constaxutil_env_t *env);


so this gives me access to the soap fault message as a axiom_node_t*. And
upon error in the 'add' operation, I just return it to the client. Is this
the right way to do it? I am missing something here.

Now one more important thing. When I call axiom_soap_envelope_get_base_node,
it seems to returning a soap1.2 fault message rather than a soap1.1 message
even though I set *

*soapVersion = AXIOM_SOAP11;

Why is that? Is there a way to get soap1.1 fault message?


I hope my questions are clear. Thanks so much for your help!

SOAP fault builder

[Subra A Narayanan]

Hello folks,

I am trying ti build a SOAP1.1 fault and return to the ws client. I am
having some difficulty understanding how to go about this. I have tryng to
dig through the source code but was wondering if you guys have some sample
code. If you have it that would be very helpful in understanding the usage.

In the meantime I will continue to dig through the source code to try to
understand.

Thanks as usual!

Re: axiom_data_handler_get_input_stream

[Subra A Narayanan]

Just some additional comments:

I think we definitely need the length function because there is no other way
of retrieving the length of the input stream as the definition of the
axiom_data_handler struct is in data_handler.c file and not in
axiom_data_handler.h file. So my question is, should the declaration of the
axiom_data_handler struct be moved to axiom_data_handler.h file?

I have made these simple changes to my local copy of the files. If you want
I can send it over to you guys and you can check it in after reviewing the
changes.

Thanks!!

axiom_data_handler_get_input_stream

[Subra A Narayanan]

Hello folks,

I was looking at data_handler.c file and came across this function


AXIS2_EXTERN axis2_byte_t * AXIS2_CALL
axiom_data_handler_get_input_stream(axiom_data_handler_t *data_handler,
const axutil_env_t *env)
{
return (axis2_byte_t *)"";
}


The above function always returns null. Should the above line be:

 return (axis2_byte_t *)data_handler->buffer;


Also, would it be useful to have a function called
axiom_data_handler_get_input_stream_len?

Thanks Samisado let me know what you find out with your tests?

Also I created a JIRA issue requesting attachment caching support be added
to Axis2/C. Here is a lnk to the issue:

Re: Large Attachment support in Axis2/C

[Subra A Narayanan]

Samisa,

One more thing that I noticed today was that the web server where my service
is running becomes non-responsive when it is receiving an attachment. I
should let you know that for the time being, i am using my laptop as the web
server. i am running 64 bit linux using VM ware virtual machine on windows
xp professional. Is there any way I can change axis2/apache settings so as
to improve the performance?

Also is there any recommended limit on attachment size in Axis2/C since
caching is not available yet? I was easily able to transmit a 3.5 MB file
but when I tried a 5 MB file, the server recvd only a part of the file about
2.8 MB.

Thanks so much for all the help.

Re: Large Attachment support in Axis2/C

[Subra A Narayanan]

Do you have an approximate idea as to when you will be implementing
attachment caching support in Axis2/C? That would be a great feature to have
and it will greatly help my development efforts. Do you want me to create a
JIRA issue so that this gets prioritized?

How do I tell if the client is using chunking or not? Just by looking at the
HTTP headers? I will do that once I get to work today. My client is also
written in Axis2/C. Is there a way to explicitly turn chunking on/off?

TIA

Large Attachment support in Axis2/C

[Subra A Narayanan]

Hello folks,

My webservice receives/sends attachments from/to clients using Axis2/C MTOM.
Today we noticed that when a client was trying to send a 1.3 MB file, the
server only received about 1/2 of it (around 760 KB)
I was reading the MTOM guide

=> http://ws.apache.org/axis2/1_2/mtom-guide.html#41


Under advanced topics, it talks about  file caching for large files  in
Axis2/Java. Is similar kind of support  available in Axis2/C as well?  I
looked at the axis2.xml file and there is nothing in there.

The application I am working on requires to support the sending and
receiving of very large files.

As usual thanks  for all the help!

Re: [Axis2/C]: SOAP request with line breaks fails

[Subra A Narayanan]

Samisa,

Good news. This morning, I built and installed Axis2/C from latest source
code on a different machine than I was using earlier. Now soap requests with
line breaks works fine.

I am thinking the earlier machine that I was using had some environment
issues.

Thanks a lot everyone for looking in to the issue!

Re: Axiom Questions

[Subra A Narayanan]

Hey Kaushalye,

I noticed that ip_stream is of type axis2_byte_t. Looking at the definition
of axis2_byte_t in axutil_utils_defines.h, I realized that it is nothing but
a char. I am wondering if I read a part of a binary file from disk using
pread and store the read data in void *buffer and then type cast the buffer
in to a axis2_byte_t, if that will cause a problem?

Does my question make sense?

TIA

Re: [Axis2/C]: SOAP request with line breaks fails

Samisa,

Its still the same case. Request with line breaks fails, without the line
breaks works fine.
I started the simple axis server with gdb. I didnt get a backtrace at all.

Re: Axiom Questions

[Subra A Narayanan]

Hey Samisa,

With regards to my second question:

I am not talking about reading part of the attachment. What I am asking is
can I read part of the file from the disk and attach it to the message?
'axiom_data_handler_create' takes in a file name but no offset. I can read a
part of the file using pread, but but do I convert the void *buff in to a
data handler?

Axiom Questions

[Subra A Narayanan]

Hello everyone,

Its Monday morning and I am back with my questions. :-)

Not sure if these questions belong here but will ask anyways. Please let me
know if I should be sending this mail to some other mailing list.

I am using Axis2 and have 2 basic questions about Axiom. I did some
searching on the web and tried looking through the Axis2/C source code but
don't have my answer. Here it goes:

Q1) I have a web service with 4 operations. The first 3 parameters are the
same for all the 4 operations. In other words, the first 3 child elements
inside the  are the
same for the 4 operations. So I created a function, called ReadFirst3Params
which gets called from all the 4 operations. Since, Axiom is based on a pull
parser, I know I have to have a reference to the 3rd parameter node to be
able to read the 4th parameter. Now my question is, do I need to return a
reference to the 3rd parameter node from my ReadFirst3Params function so
that I can continue reading the other params in the operation. Or is there
any other way of doing this. For e.g. an internal pointer that Axiom
maintains which will tell me the position with in the XML document. (I hope
my question makes sense)

Q2) One of the operation returns an attachment to the client as an mtom
attachment. I use axiom_data_handler_create to read in the binary file. I
have a requirement to be able to read in a part of the file rather than the
whole file. Just like pread function in 'C' where I can specify an offset
and the file is read from the beginning to the offset. Is there a function
in axiom to be able to do that? If not, how do I solve the above problem?


Thanks again for ur help!

Re: [Axis2/C]: SOAP request with line breaks fails

[Subra A Narayanan]

Hey Samisa,

It still doesn't work. Anything else that I can do to solve this problem?

Initially I was using Ruby to write the client. But that doesn't work
because Ruby inserts line breaks in the SOAP msg. So for the time being I am
using Axis2/C for client code as well. But the consumers of my web service
might write client code in any language/platform and that will break my
server code.


Thanks!

Re: [Axis2/C]: SOAP request with line breaks fails

[Subra A Narayanan]

Samisa,

Where should I run the distclean from? I mean which folder?

My original installation was in /usr/local/axis2c. I deleted the whole
axis2c folder and built everything from scratch today. Do you think I still
need to run distclean and will that solve my problem?

Pls let me know.

Thanks so much.

Unable to run client code

[Subra A Narayanan]

Hello folks,

I am trying to write a client using Axis2/C to connect to a Axis2/C web
service. These are the steps I followed

1. Created a wsdl file by hand for my web service.

2. Used the WSDL2C tool to generate the client stubs. Here is the command I
used

java org.apache.axis2.wsdl.WSDL2C -D
org.apache.adb.properties=/org/apache/axis2/schema/c-schema-compile.properties-uri
myservice.wsdl -l c -d none

3. Added code to the generated .c file

4. Compiled the client code using the following command

gcc -o hello_clnt -I /usr/local/axis2c/include/axis2-1.1/ -L
/usr/local/axis2c/lib/ -l axutil -l axis2_engine axis2_stub_myservice.c

5. Tried running the client and got this error

./hello_clnt: error while loading shared libraries: libaxutil.so.0: cannot
open shared object file: No such file or directory


What am I doing wrong? Am I missing any compiler options?

Thank you everyone for the help!

Re: [Axis2/C]: SOAP request with line breaks fails

[Subra A Narayanan]

Hey Manjula,

I got the latest source code from svn and built it. I am still getting an
error when there are line breaks in the incoming SOAP request. I did an svn
update and this is what it tells me:

[devwsserver:~/axis2c-svn/c]$ svn update
At revision 563913.

Was the bug fixed in the above mentioned revision or some other revision.

The server just hangs up when the request is received.

Sanjaya,

I installed the latest version of pkg-config and that solved my build
issues. Thanks!!

Subra

Re: [Axis2/C]: SOAP request with line breaks fails

[Subra A Narayanan]

Hello all,

After I sent my first mail this afternoon, I thought of starting fresh and
building axis2/c from source again. So I deleted the axis2/c source
directory from my  file system, created a new directory, checked out latest
axis2/c code from svn and try building again. this time by axis2/c build
itself failed (as comapred to the samples build fail earlier) with a similar
error. Here it is



...
checking for sys/appleapiopts.h... no
checking whether to build libxml2 xml parser library... configure: line
21319: syntax error near unexpected token `PARSER,'
configure: line 21319: `PKG_CHECK_MODULES(PARSER, libxml-2.0)'


looks like it doesn't like something about PKG_CHECK_MODULES.

Any help is greatly appreciated.

Re: [Axis2/C]: SOAP request with line breaks fails

[Subra A Narayanan]

Hey Manjula,

I checked out the latest source code from svn and built it.

But when I try to build the samples, I get an error. Since there is no
configue.sh file in the samples directory, I had to run the build.sh script
file. It dies half way through. This is the error I get

...
...
checking for string.h... (cached) yes
checking for an ANSI C-conforming const... yes
./configure: line 20467: syntax error near unexpected token `LIBXML2,'
./configure: line 20467: `PKG_CHECK_MODULES(LIBXML2, libxml-2.0)'
make: *** No targets specified and no makefile found.  Stop.
make: *** No rule to make target `install'.  Stop.


I would like to mention that when I tried building axis2/c from source, it
complained about pkg-config version should be atleast 0.20 and I had 0.19.
So I downloaded, built and installed pkg-config 0.22 version. It was
installed in the /usr/local/bin directory as compared to version 0.19 which
was installed in /usr/bin directory.

Thanks for the help!

Re: Service compilation problem

[Subra A Narayanan]

Thanks Samisa.

I tried your solution and it worked for the 'math' sample.

So I tried the same thing with my own web service, but that fails. This is
what I see in the axis2c log. The processing just stops after this line ==>
"class_loader.c(135) Object loaded successfully
" as you can see below. So I modified the make file that came with the
samples so that it now builds my own webservice too along with the other
sample web services. And that makes my web service work!!!
I have no idea whats going on here. Any help is greatly appreciated!

Hey Samisa,

I am using Axis2/C 1.0, source distribution on Linux. I compiled the source
with the apache http module.

Thanks for your follow-up abt my earlier issue. I will respond to that email
separately so that someone following that thread will also benefit.

Thanks again for ur quick response!

[Axis2/C]: SOAP request with line breaks fails

[Subra A Narayanan]

Hello everyone,

I found an interesting issue today and was wondering if someone else has
seen tha same issue before. I am using Axis2/C on Linux.

I have a web service running. When the client tries calling the web service
using SOAP, the web service works if there are no line breaks in the SOAP
request. If there are any line breaks, the server just crashes. So for eg

==> This works (SOAP msg with no line breaks)

http://schemas.xmlsoap.org/soap/envelope/
">jordan
sircharles.gif
1234

==> while this fails (formatted SOAP msg with line breaks)

http://www.w3.org/2001/XMLSchema-instance";
xmlns:env="http://schemas.xmlsoap.org/soap/envelope/"; xmlns:xsd="
http://www.w3.org/2001/XMLSchema";>
  
  
http://www.xyz.com/2007/07/";>

==>This is what I see in the axis2.log file

==> so basically the server restarts after the "class_loader.c(135) Object
loaded successfully" step.

The client code was written in Ruby. I dont know how I can tell Ruby not to
insert line breaks. But have you guys seen this issue before? Do you know a
solution to this problem?

Re: Service compilation problem

[Subra A Narayanan]

Hello Sahan,

I am not using the simple axis server but the apache HTTP server. I built
from axis2/c source and specified the correct option to build the apache
http server module.

my math service works if i use the following commands

./configure
make
make install

it doesn't work if I try to compile using these commands

gcc -c -omath.o -I/usr/local/axis2c/include/axis2-1.0/
-L/usr/local/axis2c/lib -fPIC math.c
gcc -c -omath_skeleton.o -I/usr/local/axis2c/include/axis2-1.0/
-L/usr/local/axis2c/lib -fPIC math_skeleton.c
gcc -shared math.o math_skeleton.o -L/usr/local/axis2c/lib -laxis2 -
olibmath.so


what am i doing wrong?

TIA

Service compilation problem

[Subra A Narayanan]

Hello folks,

I am trying to compile the 'math' service from the samples directory without
using the make file provided with the samples. I used the instructions from
the Axic2/C manual (http://ws.apache.org/axis2/c/docs/axis2c_manual.html)

I used the following commands to compile:

gcc -c -omath.o -I/usr/local/axis2c/include/axis2-1.0/
-L/usr/local/axis2c/lib -fPIC math.c
gcc -c -omath_skeleton.o -I/usr/local/axis2c/include/axis2-1.0/
-L/usr/local/axis2c/lib -fPIC math_skeleton.c
gcc -shared math.o math_skeleton.o -L/usr/local/axis2c/lib -laxis2 -
olibmath.so


I see a libmath.so file being generated. But my service doesn't work. I do
realize that the above commands do not generate the following files which
are generated if I use the make file:

libmath.a
libmath.la
libmath.so.0
libmath.so.0.0.0


What am I doing wrong? I am trying this so that I can compile my own web
services without having to rely on the make file. I have written my web
service but I cannot test it as I am stuck at this point.

Any help or pointers in the right direction would be greatly helpful.

TIA

Subra

Re: Generating WSDL for a Axcis2/C Web service

[Subra A Narayanan]

Hey Samisa,

I dug through the axis2c source code and found that I should be naming my
wsdl file service.wsdl and place it in the 'myservice' sub directory under
services directory (basically the same directory as the services.xml file).

Even that doesn't work? What am I doing wrong? Do I need to set 'wsdl_path'
to something in my services.xml file?

Thanks a lot for ur help!

Re: Generating WSDL for a Axcis2/C Web service

[Subra A Narayanan]

Hey Samisa,

I created the wsdl for my service by hand. Where exactly are we supposed to
place it and what exactly should it be named?

I named it mywebservicename.wsdl and placed it in the services directory.
that didnt work.
i placed it in the mywebservicename folder under services diretory, that
didnt work either.

do i hv to create a wsdls folder somewhere and place it there?

ur help is greatly appreciated.

Fwd: [Axis2/C] Attachments in Axis2/C

Hello Samisa,

Any input from ur side abt the issue described below would be greatly
appreciated.

Hello Samisa,

Thanks for the quick reply. Your answers are helping me understand whats
doable and whats not.

One of the requirements for the project that I am working on is that we have
to let the clients make REST calls to our web service.

Having said that, one more clarification. Pls tell me if this is
theoretically possible to achieve in Axis2/C. And I apologize in advance if
what I am saying doesn't make much sense:

--> I will have a Axis2/C web service with REST enabled.
--> A non Axis2/C client would make a REST (HTTP POST) call to this web
service with a MIME attachment (along with some other parameters that tell
the WS what to do with the attachment).
--> Axis2/C framework on the server side delivers this request to the server
code as a SOAP message.
--> The code retrieves the attachment and the other parameters, processes
the request and returns a response.

Please let me know if what I said makes sense and if its doable.

Thanks a lot for your help!!

Generating WSDL for a Axcis2/C Web service

[Subra A Narayanan]

Hello,

How do I generate a wsdl for a Axis2/C web service. I tried
http://192.168.0.102/axis2/services/echo?wsdl but it gives me the following
error


The XML page cannot be displayed

Cannot view XML input using style sheet. Please correct the error and then
click the Refresh  button, or try again later.

--

Invalid at the top level of the document. Error processing resource '
http://192.168.0.102/axis2/services/echo?wsdl'. Line 1...

Unable to retreive wsdl for this service

 I get the above error for all the sample web services.

Any pointers in the right direction would be much appreciated.
