Re: [Axis2] MessageContext w/o any properties

ok deprecated Constants.HTTP_SERVLET_REQUEST and made sure that
HTTPConstants.MC_HTTP_SERVLETREQUEST works.

Why do we have both these constants? It seems like a bug to me!

The transport details for a given message context are only available
from that message context. So if you're processing the incoming message
then you can look up the transport info from that message context. If
you're processing the outgoing message (of an IN-OUT MEP) and want the
servlet context associated with the incoming message, then you need to
get the incoming MC from the operation context and then ask it for the
transport info.

Hi Deepal,yes it works now ! I'm using the nighlty build fom July 16th. To summarize -- the way that you indicated is the *only* way that works, that is to say :- you must use Constants.HTTP_SERVLET_REQUEST
 (and not HTTPConstants.MC_HTTP_SERVLETREQUEST) ;- you must use msgCtx.getProperty() (and not msgCtx.getOperationContext().getProperty() )Otherwise the HttpServletRequest won't be found.Thank you very much !

Hi 

Could anybody tell me how do I get the HTTPServletRequest object in Axis

Hi Heikki;

I am sorry for my mistake , I thought that you are invoking service
using http post ,
there was a problem in http get and I fixed that in current code base ,
so you will be able to get the HttpServlet Request  using

httpServletRequest = (HttpServletRequest)
msgContext.getProperty(Constants.HTTP_SERVLET_REQUEST );

if you use either nightly builds or current svn code .

Re: [Axis2] MessageContext w/o any properties

[heikki]

Yes, I'm sure.. it happens before invocation of the SEI. Just to verify I put in your code snippet, added printlns about the results :    if ( msgContext.getFLOW() == MessageContext.IN_FLOW ) {    // get servlet context, request object
    final ServletContext servletContext = (ServletContext) msgContext.getProperty(Constants.SERVLET_CONTEXT);    if(servletContext == null) {    System.out.println("servletcontext is null");
    }    final HttpServletRequest request = (HttpServletRequest) msgContext.getProperty(Constants.HTTP_SERVLET_REQUEST);    if(request == null) {    System.out.println("httpservletrequest is null");
    }        }  this puts out :servletcontext is nullhttpservletrequest is nullSince this code does do it for you, I'm really starting to wonder what might be wrong. Might it be due to my using WebLogic, incl. the  classloader setting ? Or might it have to do with the particular nightly build I'm using (from about 3 weeks ago) ?
As you can guess: any help, tips and advice is very welcome !Heikki DoelemanOn 7/13/06, Carsten Ziegeler <

Re: [Axis2] MessageContext w/o any properties

[Carsten Ziegeler]

Just to be sure, are you sure that your handler is only invoked for
incomming request? (I did this mistake and then run into an NPE as the
servlet request object is only available in the incomming flow, and I
tried to access it on the outgoing flow as well).
So this is my code which actually works for me:
if ( messageContext.getFLOW() == MessageContext.IN_FLOW ) {
// get servlet context, request object
final ServletContext servletContext = (ServletContext)
messageContext.getProperty(Constants.SERVLET_CONTEXT);
final HttpServletRequest request = (HttpServletRequest)
messageContext.getProperty(Constants.HTTP_SERVLET_REQUEST);
}
And they are both not null.

thanks for the tips, alas I'm still not getting the HttpServlet Request ..I tried, in the handler :1. Deepal's tip :httpServletRequest = (HttpServletRequest) msgContext.getProperty(Constants.HTTP_SERVLET_REQUEST

My handler is used to process incoming messages; how could I get things from outgoing MC at this stage ? Could you explain what is meant here?Does anyone have more advice on how I could obtain the HttpServletContext in a handler that operates on incoming messages?

Re: [Axis2] MessageContext w/o any properties

[Carsten Ziegeler]

This is a bug in the MessageContext which has been discussed recently on
 the dev list. The getProperties() method of the MessageContext always
returns an empty map. So you can only get those properties you know the
key of by calling getProperty(key).

You need to call
msgCtx.getProperty(Constants.HTTP_SERVLET_REQUEST);

Re: [Axis2] MessageContext w/o any properties

[robert lazarski]

When using properties in a handler, try this:

messageContext.getOperationContext().getProperty(
   HTTPConstants.MC_HTTP_SERVLETREQUEST);

The way this works is explained here:

http://marc.theaimsgroup.com/?l=axis-dev&m=115255047000592&w=2


In addition it seems that the outgoing MessageContext objects do not
contain the servlet context. Is this by mistake or by design? If it's
the latter, how can I access the servlet context?


Its by design- you have to get the operation context from the outgoing
MC and then get the incoming MC from that and look there for the servlet
context and any other "incoming" info.

and here to discuss a problem on its way of being resolved:

http://marc.theaimsgroup.com/?l=axis-dev&m=115260394402411&w=2

I personally use
messageContext.getFLOW() == MessageContext.OUT_FLOW  and
messageContext.getFLOW() == MessageContext.IN_FLOW to determine which
one I'm in, but you can uses LABEL as well.

Hi there,

I looked at all the properties I could get from MessageContext, using this
code

Map propsMap = msgContext.getProperties();

System.out.println("msgContext props map is empty !!!  ");
}
Set propsSet = props.entrySet();
if(propsSet.size() == 0) {

which put out this

msgContext props map is empty !!!
msgContext props set is empty !!!

Apparently, I don't have any property in the MessageContext in the handler.
Is this usual? Should I take some extra step somewhere along the line?

My purpose of getting HttpServletRequest is to retrieve URL params from the
HTTP GET request. Is there another way to do achieve this?

 Map propsMap = msgContext.getProperties(); if(propsMap.size() == 0) { System.out.println("msgContext props map is empty !!!  "); } Set propsSet = 
props.entrySet(); if(propsSet.size() == 0) {  System.out.println("msgContext props set is empty !!!  "); }         HttpServletRequest httpServletRequest = (HttpServletRequest)

Hi,

from where did you obtain the msgContext object?
