How to use event to send session parameter

Dear all,
I need to work with session information. I knew that we can send
session information to Java engine by using event. Anyway, I don't know
how to do this. Who used to do this please tell me or tell me where I
can read this is also OK. Thanks in advance.

Re: How to use event to send session parameter

There can be two cases:
1) In the request-map you are using Java Engine. In this case of a Java
Event you can get the session object from a request object available to you
in the event by useing *getSession()* method on request object. Now you can
get all your required session infromation from the session object.
There are lots of examples that you can find in OFBiz for this approach.

2) In the request-map you are using Service engine, and in the service
definition you are using engine type of Java. In this case session object
is not available to you, but it can be made availabel by adding an IN
attribute to your service definition in the following way: <attribute
mode="IN" name="session" optional="true" type="
javax.servlet.http.HttpSession"/>.
Now you can get this session object in your Java Service from the
context map in the following way:
HttpSession session = (HttpSession)context.get("session");

I think this way you can access the session information.

Re: How to use event to send session parameter

Dear Miridul,
I use Service engine and I tried follows your suggestion. But I got
problem like this:

2008-03-24 20:03:16,468 (http-0.0.0.0-8080-Processor3) [
AssetServices.java:37 :INFO ] session : null

but in log file I can see:

2008-03-24 20:03:16,437 (http-0.0.0.0-8080-Processor3) [
RequestHandler.java:245:INFO ] [Processing Request]:
createAssetPrototype sessionId=C24B7F75CEE3F8413665F3D314BAFE98.jvm1

This line is print from RequestHandler.java. How can I get this
sessionId in createAssetPrototype
*
My code*
sevicedef.xml
<service engine="java" name="createAssetPrototype"
location="org.ofbiz.prototype.AssetServices" invoke="createAssetPrototype">
<description>create asset</description>
<auto-attributes mode="IN" entity-name="SimpleAcc" include="nonpk"
optional="true"></auto-attributes>
<attribute type="String" mode="OUT" name="accid"
optional="false"></attribute>
<attribute mode="IN" name="session" optional="true"
type="javax.servlet.http.HttpSession"/>
</service>
*
Java code*
AssetServices.java
public static Map createAssetPrototype(DispatchContext dctx, Map
context)throws IOException{
....
HttpSession session = (HttpSession)context.get("session");
Debug.logInfo("session Kae: "+session, module);
.....
}

Please help me,
Nattanicha

Re: How to use event to send session parameter

Nattanicha,
You have just added the session object as an IN parameter in your
service. You will also need to pass the session object to the service. I
mean to say that wherever you are preparing the input map for this
service/request, may be from some form or some other event, you will get the
session object there and pass it to the service in the input map.
e.g. If you are using an ftl, you can write following code in your form:
<#assign session = request.getSession()>
<input type="hidden" name="session" value="${session}"/>
I think this way you can get the session object in your service.
If you are using form-widgets than you may use bsh to get the session object
from request.

RE: How to use event to send session parameter

mridul

I tried this and got this exception:

Type conversion of field [session] to type [javax.servlet.http.HttpSession]
failed for value "org.apache.catalina.session.StandardSessionFacade@79ae56":
org.ofbiz.base.util.GeneralException: Conversion from String to
javax.servlet.http.HttpSession not currently supported

The ftl file looks like this:

<#assign session = request.getSession()>
<input type="hidden" name="session" value="${session}"/>

The servicedef looks like this:

....
<attribute name="session" type="javax.servlet.http.HttpSession"
mode="IN" optional="true"/>
</service>

This would really be nice to get right to avoid using the alternative
public static String mymethod(HttpServletRequest request,
HttpServletResponse response)

I looked in ObjectType.java file and the only supported conversions are for
simple types like Double, Integer, etc.

Note that the url parameter is passed as
?session=org.apache.catalina.session.StandardSessionFacade@79ae56

Hopefully, there is something I am missing.

Re: How to use event to send session parameter

I think you can try to typecast the session object when you get it from the
context map in your service. If still you didn't get any success with that
then I think the best and most preferable approach would be to simply right
a Java Event as you mentioned in your last mail, like as public static
String mymethod(HttpServletRequest request, HttpServletResponse response).
Generally in a case where we need to access and work on request and session
objects, I think the preferred approach is to write a Java or Simple event.
I would have personally preferred that :).
