How to Intercept Http requests by Application Server plugin ?

Hi all,
My requirement of "Application Server plugin/filter" is to intercept all Httprequests coming to an
Application Server instance (and not webserver), get the related information from the request, do whatever
i want to do and then forward the request based on the info available in the request header to any webapplication or EAR deployed in the application server.
I do not want to implement as a Servlet filter in a webapp. which is intrusive to the webapp.
as we are aware, Servlet Filters can be attached to resources in a Web application and are configured in the web.xml file.
I have tried out my requirements in Tomcat as follows, it works:
In Tomcat, Valves are attached to a Tomcat container and are configured using a <Valve> element in the server.xml file.
We have modified RequestDumperValve Filter ( source available) class extending Valve to intercept Http requests.
I perform whatever i want to do in this custom Filter and then able to forward to the next valve in the valve chain of Tomcat container. I have Configured this valve in server.xml and it works fine.
My queries are:
1. Can i do it the same thing in SunONe application server or other IBM Websphere application server ?
2. Do the commercial appservers expose their APIs ( e.g. like Valve in Tomcat ) such that i can implement an application server plugin ?
i.e. Are there any such Filter classes available which will intercept the Http request processing pipleine
in application server ( precisely, its web container )
If so, can you pls provide pointers for SunONE application server and IBM Webpshere application server
3. Is this against J2ee specs ?
Appreciate if you can provide me any clues, tips, solutions, pointers regarding this problem.
thanks and regards
rajesh

Thanks for the info, vbk.
Actually we are looking filers not at the servlet level in a web application.
We are looking ways for the filter to work at web container level across different web applications... That is whatever comes to the application server, should hit at this filter ,then we perform some processing, analysis and then continue for the correspnding web application
thanks

How to convert HTTP to HTTPS in Oracle Application Server 10g(10.1.3)

Can you please suggest notes to convert HTTP to HTTPS in Oracle Application Server 10g(10.1.3) as we need this to integrate the custom apps with EBS(12.1.3)?
Appreciate your quick response,

For Oracle EBS R12, the docs provided above should be helpful. If you want to configure the application server with SSL (assuming you have 10gAS installed), please refer to Oracle AS10g documentation -- Secure Sockets Layer (SSL)

Hi,
Did you actually try to look at the Oracle Hyperion Enterprise Performance Management System Installation and Configuration Guide for instructions as suggested ?
To redeploy a component, run the configurator that can be found in the start menu under Foundation Services. Then select "modify an existing instance". Then for Calculation manager, check the box "Deploy to application server".

Re: (forte-users) HTTP request through proxy server

No, it does not. ;)
How do you say to HTTPRequest to go through proxy?

Hi,
It works very well. I have experienced this model for a distant Forte client
calling a Forte Server service Object for instance without any environment
and without TCP access (passing through firewall for instance).
It has also worked very well to make an injectot to improve Web Enterprise

You can also use the HTTP-DC project.... You don't
need Web Enterprise for this. From what I can tell,
this is available in L.x on....
There is api documentation in M.2 (with scant
examples.)
There's a special process to put the project in your
repository (it isn't installed in the repository in
the standard install,) the documentation in M.2
(probably in M.0 too, AFAIK) that tells you how to do
this (look for HTTP-DC in the online help.)
I haven't done much with it yet, I've just installed
it. If anybody out there has examples, that'd be
great. I'll try to contribute more the moment I get a
chance to explore it....

Can any one tell me how to write open hubs to application server?

Hello Everone,
I created open hubs and my requirement is to write the file to application server. So, I created logical file name and logical paths as specified in below link.
http://help.sap.com/SAPHELP_NW04S/helpdata/EN/8d/3e4ec2462a11d189000000e8323d3a/frameset.htm
That is created 'logical file path defination' in 'FILE' transaction. Used the physical path as - 'bw/FTPOUT/BPR/GM/<FILENAME>' as given in above link..
In logical file name I used the above logical file path.
When I run the open hub, I'm getting the ABAP dump "UNCAUGHT_EXCEPTION
CX_RSB_WRITE_ERROR
12/18/2008 09:00:40"
Can any one tell me how to write open hubs to application server?

Hi David,
Goto transaction code - FILE
1) Create a Logical File Path definition, enter the technical name and description by clicking new entries and save it.(z_ftp)
2) create a Logical file name definition using cross client,
enter the logical file name = z_ftp , name = ftp , physical file = ftp_test.txt,
dataformat = ASC, Appln area = BW and Logical path = z_ftp(created from step 1).
click SAVE button.
3) Assignment of physical paths to logical paths, choose your logical path here.
enter the syntax group = UNIX
Physical path = /bwftp/....
Save it .
In the openhub,
choose definition type = file
Check the applicaion sever.
servername = dev
type of file name = Logical file
Applin server file name = z_ftp
separator = |
Hope this helps and solve your problem.
Thanks

Hi,
You can use: startManagedWebLogic.sh, it is in your domain directory and you have to execute it in this way
./startManagedWebLogic.sh managedServerName http://adminServerHost:adminServerPort
For instance, in my case I use:
unixserv01:/webportal/domains/appServerWeb/bin>startManagedWebLogic.sh managedServ01 http://pelma3w3per01.mesaperu.next:7001
You have to run it on the machine where the managed server was installed.

How to monitor Http Request and Response when load testing is going on

Hi,
can any one please let me know how to monitor http request sent and response received for each virtual ID when a load test is going on ?
Thanks,

You used to be able to see what the VUs "see" using the "VU Monitor" (it would only do a simple rendering of the HTML but it served it's purpose). However this was replaced (in v12 I think?) by the "VU Log". While this offers simlilar functionality, I have had problems getting to see the same level of detail. You may need to use the "debug" modes. Also check the "Content" tab within the VU Logs (it is the closest equivalent to the HTML you would see in the responses in the old VU Monitor).

In my company, we have a software developed by a team using Oracle Forms 6i, the application is connected te Oracle 9i Database and every thing works well.
Problem :
I was able to upgrade the database from 9i to 10g. But my question : is it possible to deploy all the Forms (fmx 6i version) on Application Server 10g. I want to use the 3-tiers architecture.
Take note that i have not the fmb source files. Just the FMX (about 40 files)
If yes, can you explain also how to proceed (tools to install on Application Server) and how to setup the connection between the 3 tiers throught a LOCAL NETWORK.

You will at least need to recompile all those *.fmb to *.fmx in the version of the App server you will be using.
We have a forms6 c/s application we are migrating to forms 11g and it almost that easy (except for changes in how you launch reports).
The application server is setup alot like the client/server side of forms is, it needs a tnsnames.ora that points to the database and it needs to know where you will be storing the forms and report. Looks for any *.fmx and that will be the default location.
