Multiple HTTP Proxies

Hi,
we have a WebLogic Workshop (8.1.5) / Integration (8.5) project which makes heavy usage of WebService controls.
We need to make the WebService calls via different HTTP proxies. Is it possible to use either
a) an automatic proxy configuration file (like in the webbrowsers)?
b) different HTTP proxies for different webservices (like using some special annotations or simmilar)?
So far, I am only aware of the commad-line -D java sytsem properties that can set the proxy server and port for the whole server. But I am looking for a way of choosing different proxies for different calls.
Is this possible?
Thanks and kind regards,
Joerg.

Proxing request to multiple http servers

Hi,
I want to proxy request to multiple http servers.
I am able to do that for one, but now i want to configue 3 more servers.
All the servers will be giving jsp pages.
Can anybody help me in doing that.

How best to make a transaction span multiple HTTP requests?

Hi, all. What is the best way to implement a transaction that spans multiple
HTTP requests? Many J2EE applications must solve this problem, but I can't
any guidelines for an implementation.
Consider an application that implements a multi-step wizard. Each step
gathers data from the user; step one gets the user's name, and step two gets
his dog's name. When the user completes the wizard, the application saves
the user & dog in two entity beans. Conceptually, the application treats
this wizard like a single, long-running transaction. The transaction begins
when the user launches the wizard. Submitting the JSP for step one adds the
Boy bean to the transaction, and submitting step two adds the Dog bean.
Finishing the wizard commits the transaction. Exiting the wizard or timing
out causes the transaction to rollback.
Although the wizard looks like a transaction, the entire sequence of user
interactions can't be captured in a single JTA UserTransaction. A
UserTransaction must be associated with a single thread, but each wizard
step is handled asynchronously by its own execution thread. It's impossible
to funnel the conversation through one thread that can demarcate the
transaction. (This would be a pretty dumb solution for other reasons, but I
don't want to get lost in details.)
I think the standard way to solve this problem is to store conversation
state in a stateful session bean (or the http session) and create / update
both entity beans in a transactional EJB method after the wizard completes.
Unfortunately, this solution prevents me from leveraging a lot of great
transaction management features provided by the app server. For example, I
can't use optimistic concurrency to make sure that the dog object hasn't
changed in the database between the start and end of the wizard. Also, I'm
forced to keep track of changes to the dog object in the conversation state,
then replicate these changes to an entity bean at the end of the wizard.
Keeping track of state in a stateful bean is pretty straightforward, but it
seems like there must be an existing solution that leverages the appserver's
concurrency and state management features. Am I missing something? Is there
code, a pattern, or an article that describes the best way to implement a
multi-step process that looks transactional? I suppose WLI does what I want,
but that feels like killing a roach with a SCUD missle. Thanks for any
advice.

I assume from your answer that I'm on my own for implementing stuff like and
transaction inheritance and tracking object modifications? Well, we'll give you a bit of help on the object modifications. The
usual pattern is when you're pushing the JavaBean back to the CMP you
call all the setXXX methods on the CMP bean. Our CMP container will
check if the value you are setting is the same as read from the db. If
so, it will not update that column.

If so, no big

I'd recommend that you include a separate version or timestamp column in
your db schema.
Then do something like this:
Client Server
1) First HTTP Request
2) Read current Dog and Boy Entity Beans
(if any) and copy their values into a JavaBean.
You want to include the version
column(s) in the JavaBean(s) along with the data values.
You probably also want to store the JavaBeans in
your HTTP Session.
3) Client proceeds through wizard interacting with JavaBeans
4) Finish with Wizard, copy JavaBean values (including
version columns) to CMP 2.0 Entity Beans.
The version column will give you the optimistic concurrency protection
that you desire without opening a JTA transaction to span user input.

Creating multiple http servers on one machine

I created multiple http servers on one machine.
I did this in the following way:
Created a http service as nt service with the following command:
apache -i -n Testservice -f d:\oracle\isuites\apache\apache\conf\httpd2.conf.
When I start the service, I always get an error:
Didn't return an error. Cannot start service.
Can someone help me.
I need two httpd services as nt service. Because, I want to use oracle fail safe. So I need a service.
Alternative : I can create batch files. But I want to start these batch files as nt service. Is there a possibility on
Windows nt to do this, or an available tool.
Thanks in advance,

          If you want to have multiplie servers in the same machine and you want to cluster them then you need ip for each instance.
          If you want multiple instances without clustering, then you can have them run on the same ip but each one should have a different port.

          If you are accessing the ejb/services on the same server using a servlet. You can get the context, simply using the default getInitialContext(). This should return the context to the local machine. This shoudnt require any ip information.

I'm not sure what you mean by the "like" commands, but if you
just use a
repeater to repeat your buttons and use ONE HTTPService that
looks at what
index the button that was clicked is in the repeater list and
sends based on
that, I'd think you'd be pretty much there.

Multiple http connection

is it possible for me to make multiple http connection to server?
I'm trying to send data for about 40kb, i send the data into 80 parts ( a part about 500 bytes)..
is it possible to make about 80 thread in the same time??
I do this way to reduce time consumption...
Help me please..

No, in this case, more threads will most likely slow down the data transfer:
- more threads means more TCP connections, means more overhead
- CPU scheduling will make it slower than using one thread, they can't work symultanious anyway
- One thread is probably already capable of fully filling the network bandwidth with data

Create multiple Still Proxies

Having a problem creating multiple still proxies. Basically what I want to do is select all the layers in a PSD imported as a cropped comp and create a half res proxy for each item. the right click "create proxy" option is disabled when I select more than one footage item. When I tried to just make my own still proxy render and output modules I couldn't set the "Timespan" (I thought if I could just set this to 1 frame it'd work). Why is it that when I right click a footage item in the project window and select "create proxy", after effects automatically "knows" I just want a still. For some reason I can't seem to recreate this in my render settings template.
Any help greatly appreciated, at the moment I am HATING having to work in HD, against all logic it's making my hair hurt.
Ed

Having tried to use this script a few times now, I'm a little befuddled. It doesn't seem (or rather I can't seem to figure out how to) set still proxies automatically to a proxy of the footage item they're supposed to be "proxy-ing". If I set it to create a movie proxy it sets the footage item up as a proxy no problem (by that I mean it automatically sets the footage created to a proxy of the original footage) but I can't seem to get it to automatically link the proxy to the footage item when i want a still proxy, post render (if anyone actually understands this their grasp of english is SERIOUSLY good). I've gone through my output settings and checked and rechecked everything and I just can't see why it's not doing it. Is it an "issue" with the script or is it just me being a script-tard?

Multiple HTTP requests using single HTTPService component

Hi,
I am having one requirement, I need to use a single HTTPService component to send request to a same and single ASP.net multiple times.
How can I acheive that..? I know that I can acheive this by sending one request at a time and after the "result" event is called for the first request then sending the second request and so on...
But if I do so then it will be delayed response as I need to wait until the result handler for the previous request is called...
So how do I do this..?
Any help greatly appreciated....:)
Thanks in advance..
Thanks,
Bhasker Chari

yep, the setting works when set to 10. Seemed to not work when set to 20. Anyways, summary is "long polling" and Flex
or Flash are not good compatriates. So, you will need to work out your own mechanism on the server or client
side to limit the sockets used/wasted. Painful but true.

Multiple HTTP requests through same connection

Hi...
I am writing an application which connect to its server through HTTP protocol and the server is basicaly a bunch of servlets hosted somewhere (Right not it in the tomcat running in my PC)
I know that with Connection Keep-Alive header you can keep the connection alive and do multiple requests from the same server.
Can some one point me to where can I find some sample code which shows how to send multiple requests through same URL conection or URL object. What i cant figure out is how to reset the URL connection or its streams a and make them send anotehr request message to the serverso server can respond.
Or do I have to do this manualy (using sockets)

You SHOULD be able to do a HttpUrlConnection method. However, I have hand-coded HTTP server and client apps and the keep-alive is rarely enabled in servers.
This is due to better handling of millions of unique hosts requesting, unlike a network os, which is made the other way around.

Transparent connections through HTTP proxies

Hi All,
I am trying to connect to internet through java application. In my application I had an object for example
SomeObject obj = new SomeObject("url"); which internally connects to the web application on internet. When I run this application I am getting connection error. Which prevents from internal firewall. How do I solve this problem. Which must be done transparently with out affecting my internal code. How can we by pass from proxy server to connect to the internet. I heard HttpClient from apache can be used. How this can be used. Please provide me some sample to overcome this.
Thanks.
Phani.

Multiple HTTP Servers with Portal

I am trying to set up 9iAS (Portal) on a server that already has several HTTP servers on it. The System Administrator wants a "web services" on a single NT box. I installed 9iAS and that seemed to complete OK but now I'm getting some errors trying to use Portal...I can't get logged in to Portal30/Portal30.
Is it possible to run several Apache servers including Portal on a single NT box?
We are moving up to Portal 3.0 from WebDB 2.2 which is on a NT box by itself.

it is possible, just install 9ias in multiple oracle_homes, if u need 2 instances of HTTP server, install in 2 Oracle homes and each could point to same Login Server. Metalink has a good note on this.

How can I set enable HTTP and/or HTTPS Proxies through command line?

I know the exact key/value to be changed; it's in
/Library/Preferences/SystemConfiguration/preferences.plist -> NetworkServices -> 46A40FA8-6E7C-xxxx-xxxx-xxxxxxxxxxx -> Proxies -> HTTP(S)Enable -> should be set to 1
I immdediately thought of using defaults write to carry this out in the command line but I don't know how (or if at all!) that works with multi-level key/values. I only have access to the first level (NetworkServices) with defaults read.
Any help would be much appreciated,
thanks \.

The networksetup utility is the program OS X uses to change the network configuration. The Network Preference Pane in system preferences is just a front end to networksetup; networksetup can do everything the preference pane can do (and possibly more).
The parameters you are interested in (from the man page):
-getwebproxy networkservice
Displays Web proxy (server, port, enabled value) info for <networkservice>.
-setwebproxy networkservice domain portnumber authenticated username password
Set Web proxy for <networkservice> with <domain> and <port number>. Turns proxy on. Optionally, specify <on> or <off> for <authenticated> to enable and disable authenticated proxy support. Specify <username> and <password> if you turn authenticated proxy support on.
-setwebproxystate networkservice on | off
Set Web proxy on <networkservice> to either <on> or <off>.
-getsecurewebproxy networkservice
Displays Secure Web proxy (server, port, enabled value) info for <networkservice>.
-setsecurewebproxy networkservice domain portnumber authenticated username password
Set Secure Web proxy for <networkservice> with <domain> and <port number>. Turns proxy on. Optionally, specify <on> or <off> for <authenticated> to enable and disable authenticated proxy support. Specify <username> and <password> if you turn authenticated proxy support on.
-setsecurewebproxystate networkservice on | off

Hi,
how to configure single HTTP server to listen on multiple ports? We have Oracle 10gAS installed RHEL 3.0 AS and changed the default port number from 7777 to 80 using the ias admin console and its working fine. But we want the 7777 port also to be active and listening so that whenever a request comes to either 80 or 7777, it should be handled by the single HTTP server which comes by default with the Oracle 10g AS.
Any kind of help would be of great help for us.
Thanks,
Balakrishna.

HTTPS to Multiple HTTP service and ports

Hello Guys,
I am trying to set up a config in a one armed design with client connecting via https that should be redirected to differents http servers (some are port 80 others 8080 and 9000) and depending on the end of the HTTPS url I have to rewrite the end of the url to connect to the right application on the server.
example i use
https://mydomain.extranet.prod/reporting and this should be transformed in http://sdourep01.rep.fr:8080/
But at the same time if the client use this https url:https://mydomain.extranet.prod/ged/appli1 it should be rerouted to others servers using port 9000.
Can someone help on how with a same VIP and a same certificate i can balance the traffic to the right servers changing the ports and rewriting the url.
Here is a sample of my config so far.
Thanks

if all you need is change the port, than can easily be done.
Create a rule to handle the SSL traffic. A single rule for all your url is ok.
Send the cleartext traffic to an ip port ie: x.x.x.x:81
Then create multiple rules for x.x.x.x:81 with different url match statement.
ie:
content reporting
virt x.x.x.x
proto tcp
port 81
add service Server1_8080
url "/reporing*"
active
Content Appli1
virt x.x.x.x
proto tcp
port 81
add service Server1_9000
url "/ged/appli1*"
active
However, if you need the url to be changed as well as the port, then you will need to configure a redirect. Then catch the redirect with a new SSL rule and forward it to the specific server.
Hope this helps.
If you need more info, let me know.
Gilles.
