Maintain the HTTP session

I am building a small J2ME application that opens a HTTP connection to the server. The application requires user authentication.
But, each time I open a HTTP connection to the server, the server creates a new HTTP session.
Is there any way to maintain the session between server calls?
Thanks

[ssljivic],
Perhaps you may want to post parts of your code that is doing the HttpConnection calls before any of us on the forum can advise or share our experiences.
Session management should be done by the webserver that your J2ME application is making HttpConnection to. The CLDC/MIDP APIs provides the RMS javax.microedition.rms package that offers a developer a way to persistently stored data on the device. Data from the RMS store can be compared with the data by the session manager on the webserver to identify the J2ME client and thus obtaining back the previous sessions' state, very much like the concepts of cookies in a normal HTTP browser.
My 2 cents worth, HTH.

Maintaining an HTTP session in SOAP

Is it possible to maintain an HTTP session when using RPC style SOAP services?
If not, how do people maintain conversational state between a client and a SOAP
server?

All is not lost though!!! Apache's SOAP implementation supports Stateful session.
Maybe u should take a look at it...

Naresh,
BEA's webservices implementation is at Stateless Session Bean level .
And
hence you are never working at servlet/jsp level. So there is no way
you can
use HTTP Session.
Also BEA's webservices doesn't support Header Element.

Well, if that is the case, we could maintain state manually by "inventing"our
own session objects. All we would have to do is to maintain a map atthe
server
end that maps a sessionId to a session. The sessionId would have tobe
passed
as a parameter to every method. (Yuck. Or can it be put into the soapheader somehow
- so as to keep the method signatures clean?) Do you see any holeswith
this approach?
"Mullai Murugan" <[email protected]> wrote:
It looks like maintaining state is not possible in the current release.
The documentation
says clearly that only stateless beans are supported.

Hi ihave maintained the http connection to enable proxy but still?

hi ihave maintained the http connection and also in sxmb_adm i have added the
entriees for specific configuration to enable proxy but still i m getting the error
->no connection to the integration builder
->on going to the connection test
i get the error SPROX_IFR_ADDRESS
and unable to get the data exchange profile
and in exchange profile i can see all the relavavt data w.r.to xi serer in connections section.
->do we also have to maintain anything relate to r3 in exchange profile

><i>do we also have to maintain anything relate to r3 in exchange profile</i>
Not needed.
Just follow Vijaya's blog on what needs to be done step by step and if still no success let us know what the error is

Maintain HTTP Session in Webservice

Hi,
I configured a Webservice as an External Resource, just for consume it.
It works OK for a single method invocation in this webservice, but I need to maintain a HTTP session between more than one invocation to this webservice. How I can configure a Webservice External resource to maintain HTTP session between methods invocations?

The option that you mentioned is just for WebServices that needs HTTP Authentication.
Is not my case.

Redirect service from http to https, session is lost

I have setup two web sites using NT 4.0 IIS so that both
          "http://nossl/mybeanbeans" and "https://ssltest/mybeanbeans"
          can execute the commerce server mybuybeans example.
          Then I modify the shoppingCartDetail.jsp and commandAssembler.jsp
          (files attached) hoping that when I click the "Checkout" button
          on the Shopping Cart screen, it will redirect the service from
          http to https.
          The URL is redirected to "https" but it depicts the welcome page
          instead of showing the Order Check Out page.
          Previous session information is lost.
          Can anyone help me?
          Thanks

the problem is when the cookie is exchanged between the browser
          and the app server IE treats request coming from http://bc.com:7001
          and http://bc.com:7002 as one and the same : so the browser maintains
          the same session but netscape treats this as responses coming from two
          different servers and hence u lost the session.
          I assume u are having this problem with netscape and not IE.
          the solution is set this property in the weblogic.properties file
          weblogic.httpd.session.cookie.domain=.bc.com

How to view and change HTTP Session Size

For the SAP Web AS Java, how can i check what size is set for the http session object?
Thanks,
Haris

Hey Vincert,
Is that parameter maintained on the ABAP stack or the Java stack.
Specifically i would like to know if the HTTP session object size is viewable/modifiable for Portal (hence standalone Java stack). I believe Portal does not have ICM.
Thanks,
Haris

In-memory replication of http session is not working in BEA7 cluster

          Hi everyone,
          I have 3 managed servers in Bea7.0 SP4 in a cluster. The client requests are sent
          through apache web server. I have given cluster address as URL in httpd.conf of
          apache server which sends the client requests for dynamic pages such as JSPs and
          servlets to the weblogic cluster.
          Load balancing is working fine. I ensured this from the log files of all the 3
          servers. All the 3 servers are getting different client requests and thus load
          balancing is working.
          Now, I wanted to achieve Fail-over. I do not think that i should use proxy plug-in
          for this. I feel the cluster itself will handle fail-over provided i make the
          http session as memory replicated.
          I updated the weblogic.xml with the following entry :
          <session-descriptor>
          <param-name>PersistentStoreType</param-name>
          <param-value>replicated</param-value>
          </session-param>
          </session-descriptor>
          I guess this is sufficient to make the http session as cluster aware.
          But when I shutdown server1, the user connected to server1 will be kicked out
          of the session and come to login page through server2 or server3 which are running
          fine.
          Could anyone help me to achieve http session as cluster aware. Does it indicate
          that I have to go for WLS proxy – HttpClusterServlet to achieve fail over for
          http session ?
          BTW, for your info, i am using setAttribute() and getAttribute() while manipulating
          the session.
          thanks in advance.


          Hi Ryan,
          Thanks for ur valuable input.
          I can see failover working.
          But, I can not continue with the same session in my application.
          I printed session Ids before and after failover, I found both are different.
          I guess session replication is a responsibility of weblogic/apache plugin.
          If not please let me know which all settings I should do to make failover working?
          Thanks again.

How to open 2 HttpURLConnections in the same session

Dear,
I'm writing a client application that use HTTP GET request to get infomation from a web-server. Before getting any infomation, the web-client need to login.
When using the browser, I can't get infomation through these steps:
First, go to the URL login.jsp?username=myUser. This username will be keep in the http session variables. Then, I can get info through the page getinfo.jsp.
Now, I want to do these steps in my java client app. My code is as follow:
      URL url = new URL("http://myhost:8080/test/login.jsp?username=myUser");
      HttpURLConnection urlCon = (HttpURLConnection)url.openConnection();
      url = new URL("http://myhost:8080/test/getinfo.jsp");
      urlCon = (HttpURLConnection)url.openConnection();I known that the session variables were lost between two openConnection() method.
So, how can I keep my session variables? (I have no permission to change code of the server).
Please help me!
Thanks!

Sorry - I missed the point about not having permissions on the server.
In that case, I would try working out how the site normally tracks the session. If it inserts a sessionId in to every link, you need to include that in your request to getInfo.jsp.
If it uses cookies, look at the headers for a field named "Set-Cookie":
for (int i=0; ; i++) {
   String headerFieldKey = conn.getHeaderFieldKey(i);
   if ("Set-Cookie".equalsIgnoreCase(headerFieldKey)) {
}Then use setRequestProperty() to send the same cookie (proably the username or a session id) to getInfo.jsp. I think that will work.
Make sure you ask the site owner if you are using this for harvesting content!

Define HTTP Session Attribute in a Custom Authenticator

Hello everyone I developed sucessefully a Custom Authenticator for WLS10 that interacts with a web service.
But now I need to provide an object to the web applications with the some user information.
I was wondering defining the object in the HTTP Session but I dont know how to do it via de LoginModule of the custom authenticator.
Can anyone provide me some tips?
thanks in advance.

What kind of user information do you need to pass on to the webapplication ? username can be retrieved by request.getRemoteUser() (after successful login).
May be you need to clarify little bit more on what you want to achieve.

Model session not in sync with Http Session

Hi All,
I have an application developed in JDev 11.1.1.4 and we are not using ADF Security for login.
The problem occurring is randomly some of the LOV on my home page are getting null (having no data). These LOVs are populated using the values passed as bind parameter from the login values (basically HTTP session values at web layer). So i added a method in all the task flow to set the session value at the model layer (default method) . Also on each call to the Am Impl call i am setting the value in the HTTP session and then invoking the method, but some how what happens is the Model level session value is not in sync with HTTP session and the list gets empty.
Any inputs what i can do to get out of this prblm ?
thnk

In this case you need to overwrite the activateState/passivateState method of your am and store/reads the values from the xml structure you get as parameters to this methods.
For more detailed information check the docs http://download.oracle.com/docs/cd/E12839_01/web.1111/b31974/bcstatemgmt.htm#sm0495
By the way, this is nothing you need to open an SR on as it's working as designed.

How can I flag HTTP session attributes to not be replicated ?

          WLS 5.1 SP8 - In memory replication of a stateful servlet. Is
          there any way to flag data that has been, or is being, loaded into
          a HTTP session so as to not be replicated ? It's a long story,
          but we have some data loaded into a hashtable, more specifically
          a Properties object, stored in our session. With the hastable
          already loaded into the HTTP session, weblogic does not detect
          when we add values to the table, and therefore does not replicate
          the changes. Which is ok since WLS is working as designed. To
          get around this we load the hashtable back into the session everytime
          we add a value to the hashtable. Yup, I know that's ugly. Anyway,
          what I'm trying to find out if is there is an attribute that we
          can set to indicate, to not replicate this data or that data.
          Something along the lines of a attribute on a per hastable value
          basis. For example, I load value A into my hashtable, then I
          need to put my hashtable into the session to get it replicated.
          Next I load value B into the hastable, and again to get it replicated
          I have to load the entire hashtable back into the session. The
          problem here is that the entire table gets replciated. Does anyone
          know if I can set an attribute on value A, when I'm adding value
          B, so as to not replicate value A when I reload the table ? Of
          course all goal is to not store so much data in the session, but
          I'm trying to find a work around until that is completed.
          Thanks,
          David


          Where can I find documentation on the details of how Weblogic decides what will
          be replicated in the HTTPSession object (for example, it only replicates attributes
          which are set or updated using "setAttribute()"?

Use HTTP Session to pass Object from Web Dynpro for Java to JSP page

Is it possible to get a handle on the HTTP Session object from within a Web Dynpro application? I want to place a Java object in there that can be retrieved by a JSP page.
Thanks in advance.

Hi Tom Cole,
You can try this. i am not sure if this will work or not.
HttpServletRequest request = ((IWebContextAdapter) WDWebContextAdapter.getWebContextAdapter()).getHttpServletRequest();
You can also try this.
IWDRequest mm_request = WDProtocolAdapter.getProtocolAdapter().getRequestObject();
HttpServletRequest request = (HttpServletRequest)mm_request.getProtocolRequest();
IWDRequest basically wraps the HttpServletRequest. if you are using NW04s then the getProtocolRequest() may not be available.

HTTP Session in Flex 2

Hi,
I want to know how to work with the HTTP Session object in
Flex 2?
Piece of code is really appreciable.
Thanks,
-Sameer

Check out the example from the docs:
http://livedocs.macromedia.com/flex/2/langref/mx/rpc/http/mxml/HTTPService.html#includeExa mplesSummary
That should get you started...

HTTP Session caching possible using WL7 JAX-RPC ?

We're using WL7, and using the JAX-RPC API to access external webservices.
Basically, we create the appropriate 'stubs' from the target WSDL using
clientgen. Then we invoke the target method. Code looks something like this:
Client_Impl client = new Client_Impl; // implementation of target
ClientPort_Stub stub = client.getClientPort();
stub._setProperty(javax.xml.rpc.Stub.ENDPOINT_ADDRESS_PROPERTY, url)
stub.invoke(args);
Now, when is the actual endpoint URL being created ? Is it when the invoke()
method is called ?
It cannot be during the constructor since I pass the target URL after that ...
My problem is that I have to call the 'invoke' method quite frequently, and hence
would like the HTTP session to be reused, rather than recreated each time. Right
now,
I construct the stub each time I have to call the target method, and I'm wondering
if
I just cache the stub and keep calling the target method each time, will the underlying
HTTP session be reused ? Any ideas ?
Currently, if I do netstat on my Sun Solaris box (where this runs), I see the
TCP
connection being recreated during each invocation ...

Hi John,
You can do multiple invokes on the same stub. There is no
need to create a new one for each invoke.
WLS 7.0 use HTTP 1.0 with keep alive. If the server respects
HTTP keep alive, then WLS will not create a new connection.
