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

That's what I'm trying to figure out. :>
re what do I mean by...
I have one jsp page, that has a an html form on it with elements that get
passed to a servlet through a submit button on the form. I would like to be
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! :>>>>
Thanks for your reply.

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

passing session attributes via the servlet call, how can you access the

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?

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.

Session management in servlet

Hi,
I am using OC4J Server.
I know the session in servlet can be managed with cookies. In addition, the session can be managed in HTTP session of OC4J. And How about the URL rewriting? Does it mean there are 3 methods to keep track of the servlet session. What are the difference of them. I am quite confused.
Thanks in advance

I see. Thanks.
So it means there are two kinds of cookies, permanent cookies and session cookies.
session cookies are used to store the session information.
I have another question. I want to write a permanent cookies to the browser and get it again even if the browser is closed.
The source code is like:
Cookie cookie = new Cookie(cookieName, cookieValue);
response.addCookie(cookie);
Then I try to write some cookies in the browser, close the browser and open the browser again and I try to retreive the cookies using the following codes but the cookies disappear.
Cookie[] cookies = request.getCookies()
if (cookies != null && cookies.length > 0) {
for (int i = 0; i < cookies.length; i++) {
Cookie cookie = cookies;
Is this the correct way to store and retrieve permanent cookies?
thanks in advance

Maintaining Sessions through Multiple Servlets and Contexts

Hi,
I have a webapplication that works like this:
* User connects to a login servlet on HTTPS
* Users information is authenticated on HTTPS
* An object is stored in the session for other servlets to validate the users access
* Authenticated users are forwarded to an HTTP page where the session is used to make sure they were granted access
My problem is this....Since I create the session in an HTTPS context, when I am in the HTTP context, I am unable to access the session and constantly get NULL. Is there any way that I can access the session from an HTTP context?

What you can do is, just login using HTTPS and switch over to HTTP
and then store data in session.That is true, but what I want in the session is basically a flag on whether or not the user was granted access. I would much rather set all that up on the secure line, and then just access it from the unsecure ones...
For example, you are creating session using the
http://testdev:port/index.jsp page.
If access the same page(with hostname)
http://10.300.20.18:8080/index.jsp, you can't get the session even
though both are same web server and same web application. Because the
browser treats it different sessionI think if you use my above solution with the explicit passing of the jsessionid, you can move from one domain to another and still maintain session. Not positive on that though...

Want to see session information through coherence console

I use coherence*web to push the http session information in,and I changed the coherence.cmd to let the configuration point to session-cache-config.xml
which is like:

Anyone have some experiences and can give me some suggestion?
I do not want to use the httpsession language in jsp, and I just want to use API to access the hpptsession information.
Thanks a lot!

Sharing the information directly by accessing the caches will be a bit difficult, because the data format for the session is highly optimized. For example, large attributes are often split out separate from the bulk of the "core" session data, to make moving the session around the network more efficient. What may be the simplest solution (depending on the application's needs) is to use a "back channel" from the ASP.NET application to the Java EE application, for example over REST. This would be a reasonable approach if there are a few items that you want to access and/or update in the session.
On the Java side, you can "get" a session using the HttpSessionContext interface, but you have to explicitly enable that feature (because it was deprecated in Servlet 2.1):
public HttpSession getSession(String sId)To enable the feature, you have to set the coherence-enable-sessioncontext property to true. This property is in the XML configuration file that is added to the WAR by Coherence*Web install (WebPluginInstaller) step. I'm not sure how this gets set up in WebLogic (since there is no separate "install" step), but it should still be supported.
Is this what you were looking for?
Peace,
Cameron.

What is session tracking in servlets?

Hi ,
I'm studying servlets I don't have the clear idea about session tracking and Why and where we need to use it. Can any one say about this.....
Thanks in advance,
Maheshwaran Devaraj

Well Mheshpmr session tracking in servlets is very important...There are a number of problems that arise from the fact that HTTP is a "stateless" protocol. In particular, when you are doing on-line shopping, it is a real annoyance that the Web server can't easily remember previous transactions. This makes applications like shopping carts very problematic: when you add an entry to your cart, how does the server know what's already in your cart? Even if servers did retain contextual information, you'd still have problems with e-commerce. When you move from the page where you specify what you want to buy (hosted on the regular Web server) to the page that takes your credit card number and shipping address (hosted on the secure server that uses SSL), now let me tell you, how does the server remember what you were buying?
Well There are three typical solutions to this problem.
1. Cookies. You can use HTTP cookies to store information about a shopping session, and each subsequent connection can look up the current session and then extract information about that session from some location on the server machine. This is an excellent alternative, and is the most widely used approach. However, even though servlets have a high-level and easy-to-use interface to cookies, there are still a number of relatively tedious details that need to be handled:
* Extracting the cookie that stores the session identifier from the other cookies (there may be many, after all),
* Setting an appropriate expiration time for the cookie (sessions interrupted by 24 hours probably should be reset), and
* Associating information on the server with the session identifier (there may be far too much information to actually store it in the cookie, plus sensitive data like credit card numbers should never go in cookies).
2. URL Rewriting. You can append some extra data on the end of each URL that identifies the session, and the server can associate that session identifier with data it has stored about that session. This is also an excellent solution, and even has the advantage that it works with browsers that don't support cookies or where the user has disabled cookies. However, it has most of the same problems as cookies, namely that the server-side program has a lot of straightforward but tedious processing to do. In addition, you have to be very careful that every URL returned to the user (even via indirect means like Location fields in server redirects) has the extra information appended. And, if the user leaves the session and comes back via a bookmark or link, the session information can be lost.
3. Hidden form fields. HTML forms have an entry that looks like the following: <INPUT TYPE="HIDDEN" NAME="session" VALUE="...">. This means that, when the form is submitted, the specified name and value are included in the GET or POST data. This can be used to store information about the session. However, it has the major disadvantage that it only works if every page is dynamically generated, since the whole point is that each session has a unique identifier.
Servlets provide an outstanding technical solution: the HttpSession API. This is a high-level interface built on top of cookies or URL-rewriting. In fact, on many servers, they use cookies if the browser supports them, but automatically revert to URL-rewriting when cookies are unsupported or explicitly disabled. But the servlet author doesn't need to bother with many of the details, doesn't have to explicitly manipulate cookies or information appended to the URL, and is automatically given a convenient place to store data that is associated with each session.

Session managing testing servlets

I am running two 5.1 sp1 servers in a cluster using in-mem replication
 with a wl proxy server, all on NT boxes. I've written three servlets:
 Login, Logout, and Test2
 Login creates a new session if one isn't present. Logout kills the
 session if there is one present. Test2 tests for the existence of a
 session.
 -- I start the server and create a new session with the Login
 servlet.
 -- I test with Test2 servlet ( I get Test2: init) and it doesn't see
 the session I had just created.
 -- I reload Test2 and it recognizes the session OK.
 -- It recognizes the session with all subsequent calls to it as well.
 -- Killing the server and making the session failover to another
 server will make the Test2 servlet not see the session for the first
 time again (If that is the first time that the servlet is loaded on that
 particular server).
 Same happens with Logout servlet. It seems that when a servlet is
 initially loaded on a server it doesn't see sessions already present but
 it picks up that info on all subsequent loads. What can I do to make
 sure all my servlets see all the sessions all the time (otherwise this
 failover demo I'm doing is quite useless).
 Thanks, Timur

 The first time (notice time) that the request is made for Test2 weblogic server is NOT reading the session info. Second request for Test2 (one you quoted) is OK.

Get client information

Hello...
I want to write servlet which get client information
IP,OS,DATE,TIME,BROWSER,SCREEN SIZE, COUNTRY and send all information
on server.
If source code possible plzzz give me..
thankx in advance...

If you write a HttpServlet (just subclass it) you have the request as a HttpServletRequest. From this object you can get information such a browser etc. Try (inside your servlet code):
PrintWriter out = res.getWriter();
out.println("<HTML><BODY>");
out.println("<H1>Client information</H1>");
out.println("Client address: " + req.getRemoteAddr() + " ");
out.println("Client host: " + req.getRemoteHost() + " ");
out.println("Client user: " + req.getRemoteUser() + " ");
out.println("Server name: " + req.getServerName() + " ");
out.println("Server port: " + req.getServerPort() + " ");
out.println("Requested URL: " + req.getRequestURL().toString() + " ");
out.println("Path info: " + req.getPathInfo() + " ");
out.println("Method: " + req.getMethod() + " ");
out.println("Protocol: " + req.getProtocol() + " ");
out.println("Query string: " + req.getQueryString() + " ");
out.println("Session ID: " + req.getRequestedSessionId() + " ");
out.println("Valid session: " + req.isRequestedSessionIdValid() + " ");
out.println("Secure connection: " + req.isSecure() + " ");
out.println("Authentication type: " + req.getAuthType() + " ");
out.println("Character encoding: " + req.getCharacterEncoding() + " ");
out.println("Content length: " + req.getContentLength() + " ");
out.println("Content type: " + req.getContentType() + " ");
out.println("Context path: " + req.getContextPath() + " ");
out.println("</BODY></HTML>");
Where req and res are the HttpServletRequest and HttpServletResponse objects passed to your servlet with doGet() or doPost().
If if doesn't work out for you - give me you e-mail and I'll send over a complete example. Please notice that screen resolution etc. isn't available in the request object. For that you need to get them with for example JavaScript and then send then as parameters to the servlet.
Good luck!

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.

How to get javabean data in Servlets.( JavaBean -- Servlet(Controller)

how to get javabean data in Servlets.
1) I am using name ,password in Jsp(View )
2) when I submit this Bean will be called and Setter methods will be called .
3) In ServletController (controller) I want to get data of javabean.
In this I have to do validation of user.
I want to pass the javabean obj as like -->
request.getAttribute("beanObj");
My intention is to get all the poperties in javabean by passing bean id
or beanobj ,
Is there any way to get all the data using bean id or beanObj.
Plz Reply,

Now in the Servlet we can get the same bean by this code:
PageContext pageContext = JspFactoryImpl.getDefaultFactory().getPageContext(this, request, response, null, true, 8192, true);
UserBean userbean = (UserBean)pageContext.getAttribute("userbean", PageContext.SESSION_SCOPE);
String userid = userbean.getUsername();
For this code to work it is needed to import 2 files:
import org.apache.jasper.runtime.JspFactoryImpl;
import javax.servlet.jsp.PageContext;
The JspFactoryImpl is in jasper-runtime.jar file provided in tomcat dir.It seems to me that you are exactly knowing what you are doing :-(
You can get a Bean stored in a Session by
request.getSession().getAttribute("userbean");
In the login.jsp page for example we have the code
<jsp:useBean id="userbean" scope="session"class="com.newproj.UserBean" />
<jsp:setProperty name="userbean" property="*" />the jsp:setProperty is not called when you click on the submit button
if fills the bean with the request values from the previous request.

How to get log information about any interface...scenario etc

I have created an package which loads file in a perticular folder dynamically.
here after loading each file i want to maintain the log i.e number of records inserted,updated,deleted,error etc,i came to know that in work repository snp_session,snp_sess_task_log, will have the statistics.but in these table records loaded available in the insert step.how do i query these tables properly,how do i get session no other information from odi.
plz help me.
Jai

Thank u.
I got one more way to solve this.
SELECT <%=odiRef. getPrevStepLog("sess_no")%> FROM DUAL
we can use this statement in a variable.
After execution of the interface we can use this variable which lets us to know session_no of previous interface then we can use this session_no to get the log by quering tables in work_rep.

Jai

Hello,
As far as I can see, that Verizon Jet Pack wireless Modem uses WPA2 to connect.

The Interface that connects to the Internet, needs to be drug to the top of System Preferences>Network>Show:>Network Port Configurations and checked ON.

Instead of joining your Network from the list, click the WiFi icon at the top, and click join other network. Fill in everything as needed.

How to get the information like IP address,Host name of connected clients v

Hi Every one,
I want to get the information like (IP Address,Hostname,Active sessions , Database Server.etc) of the connected clients
via V$Views(ORACLE).
And then I like to load these infromation into a table Client_Table.
Could some one give me suggestion that which V$ views/method I use in order to get the above information and then
how to load these information into a table Client_table?
Your suggestions will be highly appreciated.
With Regards
BILAL

You could use a LOGON TRIGGER so every session insert its own environment into your client_info table.
You could use the following view and choose whatever attribute you need:
create or replace view my_userenv (

AUTHENTICATION_TYPE ,
BG_JOB_ID ,
CLIENT_IDENTIFIER ,
CLIENT_INFO ,
