Session Variable in a Command Object

Hi all,
How would I insert a session variable in place of
Request.Form variable in the following code:
<%
Set Command1 = Server.CreateObject ("ADODB.Command")
Command1.ActiveConnection = MM_skilledovertime_STRING
Command1.CommandText = "DELETE FROM Employeedata WHERE
last5=?"
Command1.Parameters.Append
Command1.CreateParameter("MMColparam", 200, 1, 9,
MM_IIF(request.form("last5"), request.form("last5"),
Command1__MMColparam & ""))
Command1.CommandType = 1
Command1.CommandTimeout = 0
Command1.Prepared = true
Command1.Execute()
%>
Instead of "(request.form("last5"), "
it would be a (session("last5")
Thanks,
Lenny

I think you've answered your own question really :)

Session facade vs Command object pattern

Hello,
I am debating using the Command pattern as my primary strategy for implementing my J2EE enterprise app business logic and would like some advice.
The general idea is to have only a few types of abstract commands (such as a ReadComand, an UpdateCommand -- I might have a slightly finer granularity than this, I don't know) and implement each use case as a command instance. For example, I might have a command called GetOrderItemsCommand which is a ReadCommand and returns the list of order items (i.e., has a getItems() method) when execute()'d.
The result of my design will be a very small set of stateless session beans with an execute() interface. No entity beans (will use Hibernate) and may very well eventually implement a Message bean interface with a similar executeAsynchronously() type method, if eventually necessary.
I guess the popular alternative (or, more correctly, the norm) is to implement session facades for this.
However, I am attracted to the Command pattern because of its simplicity, it's rapid application development angle, its disconnected-ness from EJB (e.g., a modification to a command does not mean touching any EJB at all, just the command class), and the ability for implementing cross-cutting features (such as transactions or security, although I also plan to use an AOP solution at the POJO level). At the same time, it works as a delegate of an EJB, so it's accessible for all kinds of network clients.
I am also familiar with it's drawbacks (e.g., maintainability for large numbers of commands, per the literature, such as the Marinescu 2002 EJB Patterns book).
So, very few types of stateless session beans (though there may be many instances) -- mainly there for remote client acceessibility and the ability to leverage application-level transactions if needed.
Nevertheless, I have never tried the command pattern approach and was curious if others had feedback or case studies.
Best regards --

You normally use Command to decouple your controller from the view and model tiers. Your take on making command objects 'polymorphic' is interesting, and an angle I had not thought of. In general, I implement command objects rather like the Action class in Struts.
Each command has implements an execute() method declared in the ICommad interface. The constructor of the command object ensures that a given command has all the variables and data required to execute properly. I also create a likes() method that returns a boolean. That way, I can add all my commands to a handler and iterate until on returns true on likes().

Using a Variable in SSIS - Error - "Command text was not set for the command object.".

Hi All,
I am using a OLE DB Source in my dataflow component and want to select SQL Query from the master table I have created variables v_Archivequery
String packageLevel (to store the query).
<Variable Name="V_Archivequery" DataType="String">
 SELECT a.*, b.BBxKey as Archive_BBxKey, b.RowChecksum as Archive_RowChecksum
 FROM dbo.ImportBBxFbcci a LEFT OUTER JOIN Archive.dbo.ArchiveBBxFbcci b
 ON (SUBSTRING(a.Col001,1,4) + SUBSTRING(a.Col002,1,10)) = b.BBxKey
 Where (b.LatestVersion = 1 OR b.LatestVersion IS NULL)
 </Variable>
I am assigning this query to the v_Archivequery variable, "SELECT a.*, b.BBxKey as Archive_BBxKey, b.RowChecksum as Archive_RowChecksum
FROM dbo.ImportBBxFbcci a LEFT OUTER JOIN Archive.dbo.ArchiveBBxFbcci b
ON (SUBSTRING(a.Col001,1,4) + SUBSTRING(a.Col002,1,10)) = b.BBxKey
Where (b.LatestVersion = 1 OR b.LatestVersion IS NULL)"
Now in the OLE Db source, I have selected as Sql Command from Variable, and I am getting the variable, v_Archivequery .
But when I am generating the package and when running I am getting bewlo errror
Error at Data Flow Task [OLE DB Source [1]]: An OLE DB error has occurred. Error code: 0x80040E0C.
An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80040E0C Description: "Command text was not set for the command object.".
Can Someone guide me whr am going wrong?
Please let me know where am going wrong?
Thanks in advance.
Thankx & regards, Vipin jha MCP

What happens if you hit Preview button in OLE DB Source Editor? Also you can use the same query by selecting SQL Command option and test.
Could you try set the Delay Validation = True at Package and re-run ?
If set the query in variable expression (not in value), then Set Evaluate As Expression = True.

Session Variable in any Object

Hi, I've been developing on java, jsp and struts for a while now, and I've got something that I can't resolve:
I have some session variables in struts, such as User, role, etc... I can get the session using request.getSession() and then get them without any trouble. My design uses the MVC pattern, so I also have a Model Object. I also have a database controller class to store my model. The problem is that I wanna retrieve the session variables from the database controller, and there I don't have the request object. I could use a set, or take the parameters I need, put them on a bean and pass that bean as a parameter; but that would be very ugly, and I would have to change almost every class of my application.
Is there a way to have session variables from any object?
Thanks!!!
Leandro

nope... you have to pass the reference in like anything else.

Help building an object, setting it in a session variable and casting

Hi all,
I have a problem that I hope you can help me with. The application I am working on has a simple MVC design architecture. The problem occurs when a request is made from the application to the controller servlet. The controller servlet looks at the request type and delegates the processing to the appropriate action and model classes. The model class returns an object of a specific class type that is put into the session variable. This session variable is then cast to the appropriate class type in the jsp that renders that class. The problem is that this particular class type has an array of another class type. The array is filled in the class constructor, but is null when returned to the controller.
At run time when accessing the array I get a NullPointerException error. I can't seem to figure this one out. Any help is greatly appreciated.
Here's the code:
Controller DoPost method. The 'Action' objects are defined and initialized in the init() method.

Alternate method to writing filter for recordset using session variable

I'm not sure if this can be done. I have a user page which I'd like to return database info based upon a userid entered on another page. So far, the session variable (userid) is captured on the user page however it is supposed to return the user's name rather than displaying the session variable.
My problem is this. Within dreamweaver, I am able to create recordsets however I cannot create a filter. The connection works. At this point, I am searching for a workaround where I can tie in the session variable to recordsets. I should make mention that whenever I update the sql statement using the recordset widget, my recordset disappears. ? At any rate, heres a sample of the code sans connection strings, etc.
<%
Dim Recordset1
Dim Recordset1_cmd
Dim Recordset1_numRows
Set Recordset1_cmd = Server.CreateObject ("ADODB.Command")
Recordset1_cmd.ActiveConnection = MM_newuniversity1_STRING
Recordset1_cmd.CommandText = "SELECT name FROM table WHERE userid = '" & Session("userid_my") & "'"
Recordset1_cmd.Prepared = true
Set Recordset1 = Recordset1_cmd.Execute
Recordset1_numRows = 0
%>
On the user page, I have a 'Welcome' and the following code
{Request.userid_my}
Any suggestions? I'm afraid I'm a newbie to asp within dreamweaver cs3.

>When I insert request.userid_my code it returns the session variable
AFAIK, session variables are not part of the request object - so I do not understand why you are referencing them this way. I would use the standard reference method : Welcome <%Response.Write(Session("username"))%>
>when I insert the recordset associated with 'name' I get an Adobe End of file error. ?
Sounds like a possible problem with your installation. You may need to try reinstalling DW. How are you "inserting" this recordset and when does the error occur?
Regarding your next post...
>select name from table_name where userid = '" & namemy & "'"
>The statement consistently returns a 'quoted string not properly terminated' error.....
The select statement you quoted is obviously not complete. If you are refering to the select in your OP:
Recordset1_cmd.CommandText = "SELECT name FROM table WHERE userid = '" & Session("userid_my") & "'"
I see nothing wrong with that syntax and the string appears to be terminated correctly. If there is a different statement causing the error, please post the entire line and include a line above and below.

Javacard and session variables

Hello,
I'm trying to find a reasonable Javacard technique to handle "session variables" that must be kept between successive APDUs, but must be re-initialized on each card reset (and/or each time the application is selected); e.g. currently selected file, currently selected record, current session key, has the user PIN been verified...
Such variables are best held in RAM, since changing permanent (EEPROM or Flash) variables is so slow (and in the long run limiting the operational life of the card).
Examples in the Java Card Kit 2.2.2 (e.g. JavaPurseCrypto.java) manipulate session variables in the following way:
1) The programmers group session variables of basic type (Short, Byte, Boolean) according to type, and map each such variable at an explicit index of a vector (one per basic type used as session variable).
2) At install() time, each such vector, and each vector session variable, is explicitly allocated as a transient object, and this object is stored in a field of the application (in permanent memory), where it remains across resets.
3) Each use of a session variable of basic type is explicitly translated by the programmer into using the appropriately numbered element of the appropriate vector.
4) Vector session variables require no further syntactic juggling, but eat up an object descriptor worth of permanent data memory (EEPROM or Flash), and a function call + object affectation worth of applet-storage memory (EEPROM, Flash or ROM).
The preparatory phase goes:
public class MyApp extends Applet {
// transientShorts array indices
    final static byte      TN_IX = 0;
    final static byte      NEW_BALANCE_IX=(byte)TN_IX+1;
    final static byte      CURRENT_BALANCE_IX=(byte)NEW_BALANCE_IX+1;
    final static byte      AMOUNT_IX=(byte)CURRENT_BALANCE_IX+1;
    final static byte   TRANSACTION_TYPE_IX=(byte)AMOUNT_IX+1;
    final static byte     SELECTED_FILE_IX=(byte)TRANSACTION_TYPE_IX+1;
    final static byte   NUM_TRANSIENT_SHORTS=(byte)SELECTED_FILE_IX+1;
// transientBools array indices
    final static byte      TRANSACTION_INITIALIZED=0;
    final static byte      UPDATE_INITIALIZED=(byte)TRANSACTION_INITIALIZED+1;
    final static byte   NUM_TRANSIENT_BOOLS=(byte)UPDATE_INITIALIZED+1;
// remanent variables holding reference for transient variables
    private short[]     transientShorts;
    private boolean[]   transientBools;
    private byte[]      CAD_ID_array;
    private byte[]      byteArray8; // Signature work array
// install method
    public static void install( byte[] bArray, short bOffset, byte bLength ) {
         //Create transient objects.
        transientShorts = JCSystem.makeTransientShortArray( NUM_TRANSIENT_SHORTS,
            JCSystem.CLEAR_ON_DESELECT);
        transientBools = JCSystem.makeTransientBooleanArray( NUM_TRANSIENT_BOOLS,
            JCSystem.CLEAR_ON_DESELECT);
        CAD_ID_array = JCSystem.makeTransientByteArray( (short)4,
            JCSystem.CLEAR_ON_DESELECT);
        byteArray8 = JCSystem.makeTransientByteArray( (short)8,
            JCSystem.CLEAR_ON_DESELECT);
(..)and when it's time for usage, things go:
    if (transientShorts[SELECTED_FILE_IX] == (short)0)
        transientShorts[SELECTED_FILE_IX] == fid;
    transientBools[UPDATE_INITIALIZED] =
        sig.verify(MAC_buffer, (short)0, (short)10,
            byteArray8, START, SIGNATURE_LENGTH);I find this
a) Verbose and complex.
b) Error-prone: there is nothing to prevent the accidental use of transientShorts[UPDATE_INITIALIZED].
c) Wastefull of memory: each use of a basic-type state variable wastes some code; each vector state variable wastes an object-descriptor worth of permanent data memory, and code for its allocation.
d) Slow at runtime: each use of a "session variable", especially of a basic type, goes thru method invocation(s) which end up painfully slow (at least on some cards), to the point that for repeated uses, one often attain a nice speedup by caching a session variable, and/or transientShorts and the like, into local variables.
As an aside, I don't get if the true allocation of RAM occurs at install time (implying non-selected applications eat up RAM), or at application selection (implying hidden extra overhead).
I dream of an equivalent for the C idiom "struct of state variables". Are these issues discussed, in a Sun manual, or elsewhere? Is there a better way?
Other desperate questions: does a C compiler that output Javacard bytecode make sense/exists? Or a usable Javacard bytecode assembler?
Francois Grieu

Interesting post.
I don't have a solution to your problem, but caching the session variables arrays in local variable arrays is a good start. This should be only done when the applet is in context, e.g. selected or accessed through the shareable interface. This values should be written back to EEPROM at e.g. deselect or some other important point of time. Do you run into problems if a tear happens? I don't think so since the session variables should be transactional, and a defined point will commit a transaction.
Analyzing the bytecode is a good idea. I know of a view in JCOP Tools (Eclipse plugin) where you can analyze the bytecode and optimize it to your needs.

How to default bind variable using session variable at run time

Hi All,
I have a requirement where all VO queries (multiple VOs) produce only records that meet a certain value.
For example, I have three tables with 3 VOs and each of them has a one-to-many relationship to another table (let's call it ref table and this table has a field called release). One of the 3 VOs is a parent/master table, and the other two are child tables. I created a VO for master table that linked to the ref table and created a view criteria using the release (use bind variable) field from the ref table. The other child tables have their own VO that has view criteria that also linked to ref table using the release field.
On the UI page, I created a query component and a table from the master table VO. I also dropped the child table VOs in a tabbed panel which partial triggered by the master table. When I ran a query for a 'release' (hint: ref table value), the table for master table was filled the correct records that meet the criteria. Unfortunately, the child tables were not correct due to the query didn't use the bind variable that filter only records for the same 'release' value as the master table.
The question is how do I 'default' or dynamically set the bind variable on the child tables based on the selection criteria from the query component. I am thinking to set a session variable from the query and use it in the bind variable in the child table, but not sure how to do it.
Any suggestion how to do it or better solution to achieve the same effect?

Hi,
How about creating a custom AMImpl method, that takes parameters as required, and set the bind variables for all the desired VOs and perform executeQuery on them.
You could expose this as client interface, and then use the method as parameter form.

Using Session Variable in the Column Level Security

My Question -
1. I created an initialization block with initialization string by calling a new session variable CTP_ID_LIST in the sql command, given appropriate database connections and when I exit out of Block, and chosen Row-wise initialization. I do not see a new session variable created under variables list. Why does this happen? Please help me on this.

Hi,
This happens when you select Row-wise Initialization.
The row-wise initialization feature allows you to create session variables dynamically and set their values when a session begins. The names and values of the session variables reside in an external database that you access through a connection pool. The variables receive their values from the initialization string that you type in the Initialization Block dialog box.
You can also use the row-wise initialization feature to initialize a variable with a list of values. You can then use the SQL IN operator to test for values in a specified list.
Example: Using the table values in the previous example, you would type the following SQL statement for the initialization string:
select 'LIST_OF_USERS', USERID
from RW_SESSION_VARS
where NAME='STATUS' and VALUE='FULL-TIME'
This SQL statement populates the variable LIST_OF_USERS with a list, separated by colons, of the values JOHN and JANE; for example, JOHN:JANE. You can then use this variable in a filter, as shown in the following WHERE clause:
where TABLE.USER_NAME = valueof(NQ_SESSION.LIST_OF_USERS)
The variable LIST_OF_USERS contains a list of values, that is, one or more values. This logical WHERE clause expands into a physical IN clause, as shown in the following statement:
where TABLE.USER_NAME in ('JOHN', 'JANE')

Help Needed in checking session variable

In a sample site, I am calling a bounded task flow from an unbounded task flow. In the called taskflow the default activity is a router which checks the session variable, and the home page will be loaded only if the session variable is not null. If session variable is null router will lead to a page dispalying 'session expired'. But even after clearing the session if I copy pasted the previous url, the home page is loading. But when I call bounded taskflow from a bounded taskflow, it is working fine. Can anyone suggest any solution? Thanks in advance

Thanks for the reply. I'm using jdev 11.1.1.5.0.. I'm just trying with a sample example. I have a login page and when the user logins, the user name is stored in session. the loginpage view activity is in adfc config unbounded taskflow. The login credentials is validated in a backing bean and based on the return value, if the login is valid, a bounded taskflow 'hometaskflow' is called. In this bounded taskflow, the default activity is a router wchich checks the username stored in session. If the username is not null it will lead to the 'homepage' view. Else if it is null it will lead to a 'sessionexpired' view.
In the java class of login page I'm accessing the session variable as shown
public Username getSessionBean()
Username username =
(Username)resolveExpression("#{Username}");
return username;
public static Object resolveExpression(String expression)
FacesContext facesContext = FacesContext.getCurrentInstance();
Application app = facesContext.getApplication();
ExpressionFactory elFactory = app.getExpressionFactory();
ELContext elContext = facesContext.getELContext();
ValueExpression valueExp =
elFactory.createValueExpression(elContext, expression,
Object.class);
return valueExp.getValue(elContext);
On login button click the function being executed is as shown
public String onLoginClick() {
if(String.valueOf(itUserName.getValue()).equals("admin")
&& String.valueOf(itPassword.getValue()).equals("admin"))
Username username=getSessionBean();
username.setUsername(itUserName.getValue().toString());
return "success";
else {
return "invalid";
And to set username as null on logout, I used this function on logout click
public void clearSession()
Username username=getSessionBean();
username.setUsername(null);
The EL expression used to check the value of session variable is
#{sessionScope.Username.username==null} outcome is expired
#{sessionScope.Username.username!=null} outcome is active
This worked when I used in a bounded taskflow, which is being called from another bounded taskflow. But not working in this scenario...

How to get the session variable value in JSF

Hi
This is Subbus, I'm new for JSF framewrok, i was set the session scope for my LoginBean in faces-config.xml file..
<managed-bean-name>login</managed-bean-name>
<managed-bean-class>LoginBean</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope> like that...
So all parameter in LoginBean are set in session right ?... for example i used userId is the Parameter...
Now i need to get the the userId parameter from that session in my another JSP page.. how i get that ?..
Already i tried
session.getAtrribute("userId");
session.getValue("userId");
but it retrieve only "null" value.. could u please help me.. it's very urgent one..
By
Subbus

Where i use that..is it in jsp or backend bean...
simply i use the following code in one backend bean and try to get the value from there bean in the front of jsp page...
in LogoutBean inside
public String getUserID()
 Object sessionAttribute = null;
 FacesContext facescontext=FacesContext.getCurrentInstance();
 ExternalContext externalcontext=facescontext.getExternalContext();
 Map sessionMap=externalcontext.getSessionMap();
 if(sessionMap != null)
 sessionAttribute = sessionMap.get("userId");
 System.out.println("Session value is...."+(String)sessionAttribute);
 return (String)sessionAttribute;
 return "fail";
JSP Page
<jsp:useBean id="logs" scope="session" class="logs.LogoutBean" />
System.out.println("SS value is ...."+logs.getUserID());
but again it retrieve only null value.. could u please tell me first how to set the session variable in JSF.. i did faces-config only.. is it correct or not..

Printing a Web Report Using Firefox Results in Lost Session Variables

Post Author: AVXFlyer
CA Forum: .NET
I'm having a problem with Firefox users printing a Crystal Report from a web site.
The first page of the web site collects information to be used in the report generation, for example, start date, end date, type of report etc. These are all various text boxes, drop down lists, radio buttons and check boxes. When the user clicks to show the report, everything works fine and the first page of the report will display. The code behind this page takes care of saving al the session variables into hidden fields on the page so the settings will be accessible when the user clicks to view the next page of the report.
On clicking to view the next page of the report, everything is still fine and the process works beautifully and I've had no problems.
A new problem has surfaced during the printing of these reports. Users who use IE6.0 or IE 7.0 do not have a problem, however, users who use Firefox do have a problem.
It seems that the print dialog which appears as part of the the Crystal web control manages to 'lose" the variables which were present on the calling page. It only does this with the Firefox browser. Calls on postback to retrieve the variables from the hidden fields result in 0's or empty strings ("").
Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init .... .... If Me.IsPostBack = False Then ... ... strDiscontinuedOnly = Request.Form.Item("ddlInvStatus") If strDiscontinuedOnly = Nothing Then isDiscontinuedOnly = False Else Select Case strDiscontinuedOnly Case 0 'All Inventory isDiscontinuedOnly = False Case 1 'Discontinued Inventory isDiscontinuedOnly = True Case 2 'Active Inventory isDiscontinuedOnly = False End Select End If Else 'Postback is true intRequestedReport = Request.Form.Item("fldReportID") strDiscontinuedOnly = Request.Form.Item("fldInvDiscItemsOnly") isDiscontinuedOnly = Request.Form.Item("fldInvDiscItemsOnly") ... ... end if

Can't explain it, but here are a few tests;
1) Try to print a saved data report
2) Try to print a report that is not using parameters
3) Try a different printer driver as "default"
4) Enable the option "Dissociate Formatting Page Size and Printer Paper Size" on the report
5) What format do you export to?

How to pass a session variable to the bussines layer?

Hello,
I am doing a management application, and I need to store the login user that make insertions on any table, and the pages does not has backing beans.
I had try to do that bindding the value field of a hidden attribute with the session variable, but it only change the value of the one. My second attempt was make an javascript function to do that on the page´s load, but it not looks like a good solution.
Someone knows a way to sent the session value to the bussines layer? O a way to access from the Bussines layer to the session?
Thanks
Tony


Hi,


Another solution (that I always use) is storing simultaneously the same data in HttpSession (in view layer) and session hashtable (in businness layer).


You can put and get these data in any businness component using following methods:



private void setToJboSession(String key, Object val){
 Hashtable userData = getDBTransaction().getSession().getUserData();
if (userData == null) {
userData = new Hashtable();
userData.put(key, val);
}


and



private Object getFromJboSession(String key){
return getDBTransaction().getSession().getUserData().get(key);
}

Null session variable

Ok, i have a problem which is really annoying me and i have been stuck on for a while. I am developing a website for my brothers company and am really stuck for time for the launch date. I developed a website last year which worked fine and i am re using the code from that. I am setting a session variable "sessEmail" when the user logs in and want to retrieve it when they go to add a produt to their cart. Here is my code
String Email = request.getParameter("txtEmail");
String Password = request.getParameter("txtPassword");
session.setAttribute("sessEmail",Email);
Object o = session.getAttribute("sessEmail");
String s = o.toString();
out.print(s);
I am just printing out the "sessEmail" to make sure it is working. It works fine when i try and retrieve the session variable on the same page were i set it but on a seperate page it wont work. It is returning a null pointer exception because the session variable has no value. It is occuring when i try to convert an object to a string.
Any help would be much appreciated as i am stuck for time.
Cheers

Ok the first question to be asked is why it is null?
The most obvious answer is that you have cookies disabled, and are not using URL rewriting.
To retain the session, the server issues a "Session Cookie" with your jsessionid in it. If you have cookies switched off on your browser, it won't retain the session.
To confirm this print out session.getId() on your pages. If it continually changes, you aren't keeping your session. If it remains the same, you HAVE got a session, and need to check why you are putting a null value there.
To retain session, you need to run every link/url that gets printed to your page through the method response.encodeURL() which will add on the session id manually if cookies are not supported.
Hope this helps,

Page Specific Persistence using Session Variables

Hi, I have read a lot about using session variables to persist the ReportDocument object across page loads. This works fine if you have just one page open with one report. The problem I am having is I have a web application that makes 30 or 40 different reports available to the user. To simplify the code and make it easier to add new reports I have developed a single template aspx page that can be used to view any of the reports.
My problem is that if the user opens 2 different reports in 2 separate tabs in the browser then the session variable persistence doesn't work because the session variable is available to both tabs.
Is there a way to persist the ReportDocument object which is 'page' specific.
Thanks

Your best option is likely to have something that makes the session variable names unique. I've done such things as putting the current datetime in the url as a querystring parameter and appending that to the variable name. On each postback that querystring should persist.
You might be able to use the reportclientdocument object and serialize the report and persist through view state, haven't tried this with inproc ras though. A sample that uses the ras sdk can be found [here|http://wiki.sdn.sap.com/wiki/display/BOBJ/NETRASSDK+Samples]
