Passing session information to multiple JVM's

Is it possible to pass session information to another JVM running on another server?
Example:
Server A calls a servlet on Server B. Will the session object (and values stored in it) created on Server A be accessible to Server B.

No.This is not exactly true. If you're talking about a clustered app server implementation (for example, Weblogic supports clustering), where 'machine A' and 'machine B' are both part of the same cluster, then, generally speaking, yes, you're HttpSessions are distributed across those machines.

Boyum External Launcher Passing Database Information w/Multiple Parametes

I have a Boyum button which calls a .NET application passing multiple parameters. However, I need to add an additional parameter that passes the database name. Can someone show me the correct syntax to do so?
Thanks in advance.

FYI: Here's the syntax for calling a .NET application and pass multiple arguments (In the "Arguments" field of the "Buttons - Configuration"):
"C:\ExecutableLocation\Program.exe" | "Value1" "Value2"
If you'd like to pass values from the form in which the button resides you can do the following:
"C:\ExecutableLocation\Program.exe" | "$[$8.0.1\]" "$[$16.0.1\]"

Passing Session info between servlets

We are running WebLogic 5.1, sp 4 and Apache 1.3 on Solaris 2.6 and we are
          successfully proxying requests to the server. But we are unable to pass
          session information between servlets. We are NOT using URL encoding. We are
          instead using cookies. We believe our configuration is correct because the
          BEA example session servlet works. Does anyone have any recommendations or
          suggestions?
          Thank you,

This is a basic misunderstanding of how Java Works:
String name +r = request.getParameter(name +r);1) You can't use a + on the left part of an assignment operation - it must be a plain variable reference. This isn't like JavaScript where you have an eval(...) capability.
2) Your Strings are being defined inside the For Loop, which means they will leave scope once the loop ends and you won't be able to refer to them anymore.
3) Is there already a String value named 'name' which you are using in getParameters(name+r)? You should probably use getParameter("name"+r) instead.
What you want to do is either put the values in an array so they are easy to access:
String name[] = new String[value1];Then loop through the parameters to assign values:
for(int r = 0; r< value1; r++) { //Start at 0 to value1-1 because arrays are 0 based.
String nameParam = "name"+ (r+1);
name[r] = request.getParameter(nameParam);Now I can access the names in order:
name1 via name[0]
name2 via name[1]
name3 via name[2]
etc...Before going any further I would stop working on Servlets and go back to some good Basic Java Tutorials and books until you get a better grasp of how the language works.

Server, Multiple JVMs sources

Hi,
i've to create a (web serivce) server application. This application should be ready for clustering or something, if one server isn't fast enough.
I know already some things abou concurrency in Java. I'm no Java newbie. But i don't know how clustering works.
Does it depend on the used JVM?
Or is this for every server (i.e. Tomcat, JBOSS, ...) different?
What are the requirements in the webservice-layer and in the persistance layer?
Any good internet pages/PDFs which discusses this?
Any good books?
I really hope some can help me here, because it's very important for me.
Cheers,
Ingo

I just re-read the guidelines for a clustered web app over the weekend, so I think I've got things straight. Your application will have to be sensitive to two important issues:
1) A class which was previously a singleton may now be instantiated in multiple JVMs. The most obvious side effect of this is that the init() method of any servlet will have a different ServletConfig object passed to it for each JVM it is initialized in. As a result, the application context is no longer a valid place to store information, since the change to the application context is not necessarily propagated to the other JVMs. However, context-params will still be available from all JVMs. Another noticable side-effect is that static variables no longer work as expected (since there may be multiple instances of the same class).
2) The HttpSession object for a given session can only be in existence on one JVM at a time. If the HttpSession needs to migrate to another JVM, then it will be serialized and sent to the other JVM. As a result, adding an object to a session that is not Serializable may result in IllegalArgumentException being thrown. I'm guessing that in the case of a fail-over (node dies unexepectedly) that the HttpSession object is lost.

SSP5: Using multiple JVM for load balance performance?

Sun 12 MAY 2002
Apps 11.0.3
SSP5 patchset I
HP UX 11.0
db 8.1.7.2 (64-bit)
Load 60 concurrent sessions, each spawning 2.5 - 3 http connections.
CPU 3:750Mhz
RAM 8G
Is anybody using multiple JVM for load balance?
What is your ratio of JVM to concurrent iP sessions?
Are you running Apache/Jserv on a server with any other applications, or is Apache by itself?
If you are not using JVM, how many httpd processes do you get before Apache implodes? We stopped in the water at 90 httpd processes, but performance degraded starting at 70 sessions.
Thx - Don

Using Web Cache to load balance servlet-based Forms (6i and 9i) is unofficially supported. I say "unofficially" because we have actual customers doing it and getting support, but the 2 development teams (Forms and Web Cache) haven't actually done any integration testing of this sort of configuration yet. For your case, please contact your Support rep and ask what was done to use Web Cache as a load balancer for Forms6i at METRO in Germany. The Forms product managemment team is writing up a white paper to describe how to do it, but until then, you'll need to go through Support. Please contact me if you want more information.

Hyperion Smart Cut Session Issue streaming multiple reports at a time using

This is a lengthly post with details, Please review with Patience:
We are trying to integrate Workspace based web Analysis reports within our intranet portal, thru portlets (made from individual workspace smartcut link), so that users can customize their page as needed, Once they login thru intranet, Cookie is set and passed to succeeding smart cut links via secured http headers. This part is fine, but mainly running into issue with streaming several multiple web-analysis reports at a time,+ we are using Iframe to display and stream multiple individual reports on to one page, but unfortunately all Iframes are sharing one session rather than creating individual session, mostly because of limitation of current web analysis system architecture and IE browser behavior with sessions .
Which Hyperion reporting tool does allow to stream multiple reports at a time? ideally we want to create Iframe of each workspace report so that users can customize and pick portlets as needed. To stream multiple reports at a time.
Problem Description: Hypeiron Web Analsysis, Smart cut reports incorrectly rendering images and intermixing dash boards on POV changes upon multiple reports being diplayed at one time thru Iframe's, issue seem to mostly relate to Hyperion using single session rather to multiple session when displaying several web reports at a time.
Steps Needed To Reproduce:
User logs into workspace.
user click on expolore and able to view the report without any issues.
When right on any of the report and select properties.
Select the SmartCut url and paste it in the Internet explorer.
The webanalysis report opens without any issues.
Similarly user copies the smartcut url for a different report and paste the link on a different tab or new window of same browser.
The report on the first tab gets over written of the report of the second tab of the browser.
The issue happens when two different reports and opened on a browser with multiple tabs. The reports get over written.
Oracle development answer:
In the described scenario opening new browser window does not spawn a separate independent browser session. A new browser window is supplied with URL pointing to the same domain, so all browser cookies including the "ORA_WA_SID" (WA session cookie) are shared between the windows. But multiple application instances cannot run in the same browser session simultaneously because of session sharing. This is not actually a defect, but rather a limitation of current system architecture and browser behavior. And there is no way to fix it programmatically on the product side.

Hi MeHyper,
Your current arrangement puts most of the session handling and persistence on the client. This forces you to accept whatever the client decides to persist and propogate between browser elements (in this case iframes).
My approach would be to:
Consider coding your portlets to manage the sessions. Manage using a somewhat stateless strategy so that each request to the server requires a login and connect, retrieve, and disconnect. Each Iframe should access a different portlet url (or provide a different query) based on its content.
This way, in theory, you can invalidate the sessions and related cookies and update the various report elements independently.
Is smartview out of the question here?

Robb Salzmann

How to pass session variable value with GO URL to override session value

Hi Gurus,
We have below requirement.Please help us at the earliest.
How to pass session variable value with GO URL to override session value. ( It is not working after making changes to authentication xml file session init block creation as explained by oracle (Bug No14372679 : which they claim it is fixed in 1.7 version Ref No :Bug 14372679 : REQUEST VARIABLE NOT OVERRIDING SESSION VARIABLE RUNNING THRU A GO URL )

Passing Session variable of DATE data type to opaque view filter

Hi Everyone,
Can you guys please help me in passing session variable of DATE data type in RPD's physical layer 'opaque view' filter for Oracle database
I tried following syntax, syntax wise I didn't got getting any error, but at the same time this opaque view is not fetching any records as well. my session variable is "END_DATE" and its value is 1998/12/31:00:00:00(as shown in RPD session windows, datatype is DATETIME)
SELECT AMOUNT_SOLD, CHANNEL_ID, CUST_ID, PROD_ID, PROMO_ID, QUANTITY_SOLD, TIME_ID FROM SH.SALES
WHERE TIME_ID =TO_DATE( 'VALUEOF(NQ_SESSION.END_DATE)','MM/DD/YYYY')
SELECT AMOUNT_SOLD, CHANNEL_ID, CUST_ID, PROD_ID, PROMO_ID, QUANTITY_SOLD, TIME_ID FROM SH.SALES
WHERE TIME_ID = TO_DATE( 'VALUEOF(NQ_SESSION."END_DATE")','MM/DD/YYYY')
SELECT AMOUNT_SOLD, CHANNEL_ID, CUST_ID, PROD_ID, PROMO_ID, QUANTITY_SOLD, TIME_ID FROM SH.SALES
WHERE TRUNC(TIME_ID) = TO_DATE( 'VALUEOF(NQ_SESSION."END_DATE")','MM/DD/YYYY')
In past, I was able to pass a session variable into a opaque view filter using DATEOF function, but that was in DB2.
I appreciate your time and help

Finally, I got right format. here it is
to_date(substr('valueof(NQ_SESSION.END_DATE)',1,10), 'yyyy-mm-dd')
and here is the source from where I got this information

Getting session information in servlet?

In Apache SOAP, org.apache.soap.rpc.SOAPContext can be used as a parameter to get at session data in your servlet. The JDeveloper web services publishing wizard won't expose a method with this parameter, saying that the XML Schema mapping and/or serializer is not specified. Is there an OC4J equivalent to get at session information?

Hi.
Most definitely possible. A few months ago I coded something very similar - jsp
form, submit to a servlet. I needed to get and set session info in both the
servlet and jsp. The code was very basic (ie no tricks involved) and worked
well. FWIW both my servlet and jsp were in the same webapp.
Good luck,
Michael

re what do I mean by...
I have one jsp page, that has a an html form on it with elements that get

able to get information about the session from within the servlet. Is that
possible?
Let me know if I'm not explaining myself properly and you need more info.
I'm relatively new to this stuff. But I'm learning! :>>>>

Hrm. Whoever told you this probably meant something else. What do you mean
by a 'servlet being called from a jsp' ?

Accessing client session information in ejb

Hi!
My prblem is the following. We want to access ejb from a servlet. We need some client session information in ejb (e.g. client username, client terminal name, client ip address) for several reason. Could anybody suggest a solution other than passing all the data through the parameter list of every method?
Thanks for any help.

If you use stateful session bean, you can pass this information, when you create it.

Passing Session to Other Java Application

Dear All,
We need to pass session of SAP BO to other java application.in short we need to make single sign on between these two without using third party authentication type.
by research , i could find out extension point API which supports to environment, through which it might be possible.
I need your help on this.
Environment:
SAP BO 4.1 Sp2
Any Help on this would be appreciated.
Best Regards,

Hi all, i have one problem. I need to pass some
session to a java bean for processing.. Can i know are
there any possible ways of passing? thanks.if i understand you correctly, and you mean passing a session object
to a bean from a jsp page, do this:
have in your bean:
import javax.servlet.http.HttpSession;
private HttpSession session = null;
public void setSession (HttpSession sessionFromJsp) {
session = sessionFromJsp;
in your jsp:
beanname.setSession(session);
the variable named session is available is jsp pages,
it is an instance of the javax.servlet.http.HttpSession class,
and provides access to the client session information.

Singletons across multiple JVMs

I have an EJB application container which is spread across multiple JVMs(something like a clustered EJB container). I am using a Singleton class to hand out 'running serial numbers'. Therefore there is a Singleton class per JVM(which is not very clean but i chose this path in the absence of anything better). Each singleton comes up when it is first invoked within a JVM and reads a starting running number and a pool of numbers from the database. This way multiple Singletons will not step on each other when doling out the serial numbers and there is no need to go back to the database for every request to the 'running serial number'.
Is there some way to do some of the initialization within these Singleton's just ONCE across the multiple instances of the JVM ie. a real Singleton across multiple JVMs?
Thanks
Ramdas

Pranav,
thanks for your suggestions.
the idea of using a Session bean to access a serialized object was one of my design options when i first implemented this, but then i decided against it because of the overhead of having to make an RMI call for every request to the 'running serial number'. The application being written is for a performance benchmark, and the request to the number being done at least once for every transaction, I chose to use Singletons.
It is a clustered EJB container(not like most conatiners), in the sense that a single container is spread across multiple JVMs.
Now if your application is getting clustured
then you have a problem, in that what you can do is
what object you have made put it in JNDI context and
everytime you want to edit it pull it out edit and set
it back. This will act a your singleton object in
clustured environment accross JVM'sI did not fully understand the second part of your solution????

Accessing the same stateful session bean from multiple clients in a clustered environment

I am trying to access the same stateful session bean from multiple
          clients. I also want this bean to have failover support so we want to
          deploy it in a cluster. The following description is how we have tried
          to solve this problem, but it does not seem to be working. Any
          insight would be greatly appreciated!
          I have set up a cluster of three servers. I deployed a stateful
          session bean with in memory replication across the cluster. A client
          obtains a reference to an instance of one of these beans to handle a
          request. Subsequent requests will have to use the same bean and could
          come from various clients. So after using the bean the first client
          stores the handle to the bean (actually the replica aware stub) to be
          used by other clients to be able to obtain the bean. When another
          client retrieves the handle gets the replica aware stub and makes a
          call to the bean the request seems to unpredictably go to any of the
          three servers rather than the primary server hosting that bean. If the
          call goes to the primary server everything seems to work fine the
          session data is available and it gets backed up on the secondary
          server. If it happens to go to the secondary server a bean that has
          the correct session data services the request but gives the error
          <Failed to update the secondary copy of a stateful session bean from
          home:ejb20-statefulSession-TraderHome>. Then any subsequent requests
          to the primary server will not reflect changes made on the secondary
          and vice versa. If the request happens to go to the third server that
          is not hosting an instance of that bean then the client receives an
          error that the bean was not available. From my understanding I thought
          the replica aware stub would know which server is the primary host for
          that bean and send the request there.
          Thanks in advance,
          Justin


          If 'allow-concurrent-call' does exactly what you need, then you don't have a problem,
          do you?
          Except of course if you switch ejb containers. Oh well.

Single Sign-On and session information

I have an Oracle Portal application with many Java Web Applications. I wish to
provide Single Sign-On to this applications. I know how to configure Single
Sign-On and how to get the user login in Java. I want to store session
information such as: User First and Last Name, User Social Security Number. I
want to get this information from the database after authentication, store it
in session and then access this information from all my applications.

Are you familiarized with sys_context function?
Hope this is useful help.
