Strange problem - session attribute

Hi,
This one is really strange. I have a search field on my form. When I enter a value in the field(say 'test data') and then click 'Submit', the search is performed. To retain the above search value on the screen, I put it into a session attribute and then pick it up again from there.
The problem is, when the screen reloads after the search, only the first part of the string i.e 'test' is displayed and data disappears. Is it that when get values of session attributes in a JSP, only the value till an empty space is considered?
I would be grateful if someone could let me know if they have ever experienced the same of if there is any documentation stating this. I am totally lost!
Thanks in advance.

Greetings,
Could you please include some of your code. It seems like somewhere along the process you are either losing or not storing all the data properly.
Thanks,
-J

Problem removing session attributes

I have a problem removing session attributes
I try w/ mysession.removeAttribute("key");
but it still lives in memory. I've tried setAttribute("key", null) as the API states that will do the same thing, but it doesn't work.
I can get mysession.invalidate() to work, but I want to keep some of the attributes there, while removing another.
I get no exceptions and no errors.

Running Tomcat 4
jre 1.3.1

Actually,
response.addHeader("Expires", "-1");should be enough.
The browser should then contact the Web server for updates to that page via a conditional If-Modified-Since request. You don't want a cache disabling 'overkill', since you'd still want the page to remain in the disk cache and used in appropriate situations without contacting the remote Web server, such as when the BACK and FORWARD buttons are pressed...
Anyway, try this first, and if it doesn't solve your problem, add the other cache-disabling headers, as outlined in the previous post.
If you're using JSP, verify also that your page has
<%@ page session="true"%>

Strange problem about using JSTL

Dear all,
I've got a strange proble when using JSTL with tomcat.
I've got two strings as the following:
     String id_string = (String)session.getAttribute("user_id");
     System.out.println(id_string);
     String valid_user = (String)session.getAttribute("valid_user");
The "println" call tells me that "id_string" has a valid value.
But when I use it like this in the same page:
<a href="springapp/blog.htm?id=<c:out value=${ id_string " /><c:out value="${ valid_user }" />" >test
I can only get "valid_user"'s value.
"id_string" is not print out to the page.
Would anyone please help me out?
Any help would appreciated and thanks in advance.

"id_string" is not print out to the page.Your session attribute is called "user_id" which you're fetching correctly earlier. But in the <c:out> tag, you're trying to read "id_string" which is the name of your local variable and not in any scope. "valid_user" works because you've named your local variable the same as your scope attribute, so the value being printed out is from the scope and not your local variable. As far as I know, JSTL doesn't work with local scriptlet variables, it only access variables in the four scopes: page, request, session and application
You should use the <c:set> tag to set a variable value. Try not to mix scriptlets and tags, it's frowned upon and will probably cause you problems later.

Submitting a form with enter key causing strange problems

I am having a very strange problem with a webapp I am currently developing. I am using JSF 1.2 along with Facelets and RichFaces. I have coded a workflow/wizard 4-step process, and on some pages I have 4 submit buttons that all call different actions on the page. The users thought it would be useful to have the enter key submit the form, so I followed some online resources to trap a keypress using javascript, looking for the enter keycode and calling document.getElementById("elementName").click(). This works fine most of the time. Sometimes, though, it seems as if an entire new session is being created, and odd behavior starts happening. For example, my page will only include 2 of the 4 facelets on the screen -or- I will get NullPointerExceptions for objects that I know have been created in the session bean I am currently using -or- I will get a duplicate form Id after trying to re-submit the page. Could the javascript click simulation not be submitting all of the form elements or is the enter key also acting like its default action (the form submission) in addition to the "click"? I'm really at my wit's end here (plus it's nearly 3 AM, that never helps things). All of the buttons being clicked are standard h:commandButtons. There is some setTimeout logic included to disable the buttons on the page to prevent double clicks (I cannot disable them onsubmit because disabled buttons don't pass the right values, perhaps that's causing it, but if so, clicking the buttons with the mouse would cause that issue too, right?)
I am not posting the code (yet), but if anyone wants to take a look see and see if I am doing something really abhorrently wrong, I'm more than willing to, I'm just curious if anyone has had problems regarding javascript submission of forms via the click() method. Clicking the button does not exhibit this type of behavior. Just as a side note: I am doing different things with the enter key depending if a modal window is open (the enter key closes the modal if it's up, and if not, it submits the form via a button click).
Any help is much appreciated, if anyone has any inkling about where I should start looking for answers it would be really helpful.
Thank you.

You need to suppress the event handling after programmatically clicking the button.

Javascript to JSP question...Can javascript function set session attributes

hello,
i have a web app that, on one of its pages, displays "tabbed pane" as an image map at the top (a la amazon.com). my problem is this: each "logical" page contains separate forms that all use the same javabean. in other words, imagine that the tabs represent an account maintenance web ui for an on-line record store. the first tab might be labeled "General," the second "Contact info," the third "Shipping Info." Each uses the same account bean and displays portions of its properties relevant to the tab at hand. what i want to do is allow a user to enter the account maintenance ui, update info on the first tab, click on tab two and have the request with the changes sent to a processing jsp. yet, since each "tab" is actually a separate URL to another page, how do i get the updated info on the first tabe without adding some sort of "SAVE" button on each tab. ive considered using javascript, but dont know how to get the request params out of the first tab whn i click on another tab. is it possible to include an "onClick" function in each URL that "grabs" the updated form fields off the preceeding tab? can a javacript function set session attributes in jsp?

hello there,
wow, you've created one big mammy-jammy tool.
first, javascript cannot access, set values to the session, without having to post to another JSP. javascript is great for manipulating objects, layers, form values, etc.
you have 2 issues [if i understand correctly]:
1) you need to able to save user info for a specific tab without having to reloading the page.
---you can create a form for EACH of your tabs and POST all the information to a hidden IFRAME or LAYER for NN4. that hidden IFRAME / LAYER will load a JSP page which with all the parameters you posted to it. or you can build a FRAMESET and target that document["frame-name"].src with that same JSP.
2) handling when the SAVE INFO action should happen: hence some javascript event handler: onMouseOver, onClick, etc
---i don't know the dynamics of your tabs, but if store which tab was clicked on last, then if the user clicks on some other tab, javascript can submit that FORM to a JSP [see condition above]
you have an interesting tool. can i see?
i hope i wasn't too confusing, but your problem is sooo interesting. =)

Variable coming from a session attribute

Hello, I am developing a web application with JDeveloper 10g
I've got a View Object which is basically a query, where I use a variable:
WHERE BbCustomerOrderStatusTab.CUSTNO = :CustomerNumber
When I define CustomerNumber in a form, it works:
<af:panelForm>
<af:inputText value="#{bindings.CustomerNumber.inputValue}"
label="#{bindings.CustomerNumber.label}"
required="#{bindings.CustomerNumber.mandatory}"
columns="#{bindings.CustomerNumber.displayWidth}">
<af:validator binding="#{bindings.CustomerNumber.validator}"/>
</af:inputText>
<af:commandButton actionListener="#{bindings.ExecuteWithParams.execute}"
text="ExecuteWithParams"
disabled="#{!bindings.ExecuteWithParams.enabled}"/>
</af:panelForm>
But I would like CustomerNumber to come from a session attribute. I tried something like that:
session.setAttribute("CustomNum","IRI0001");
setCustomerNumber(session.getAttribute("CustomNum"));
with the View Object Editor -> Client Interface setCustomerNumber selected, but it doesn't work.
I tried :
String CustNum=session.getAttribute("CustomNum");
%>
<af:attribute name="#{bindings.CustomerNumber}"
value="<%= CustNum%>"/>
but it tells me that "Attribute value does not accept runtime expressions".
Does someone know how I could do that?
Thanks,
Romain

Hi,
Frank's suggestion should work.
Most importantly, don't forget to declare your bind variable in your view object !!
Your statement looks odd to me
String CustNum=session.getAttribute("CustomNum");
%>
<af:attribute name="#{bindings.CustomerNumber}"
value="<%= CustNum%>"/>
There are many ways to do it. You may try using backing bean for command button's actionlistener or action like the following
class myBackingBean
private String CustNum; //of course with getter and setter method
myButtonAction() {
CustNum = yourFavouriteValue;
OperationBinding ob = getBindings().getOperationBinding("ExecuteWithParams"};
ob.execute();
note you must declare CustomValue in your pageDef's binding to #{yourBackBeanClass.CustNum} in your ExecuteWithParams binding
I don't know and seems not being recommended to set session value in jspx.
Another way is inside your command button in the jspx
<af:setActionListener from="#{somesource.value}"
to="#{processScope.CustNum}"/>
in such case, you must declare CustomValue in your pageDef's binding to #{processScope.CustNum} in your ExecuteWithParams binding
If you have already set session value somewhere beforehand, then what you need to do is simply declare CustomValue in your pageDef's binding to #{sessionScope.CustNum} in your ExecuteWithParams binding.
I did lot of ExecuteWithParams thing and no problems occur so far.

A strange problem in smart form?

Hi,
   I met a strange problem in my smart form. When I click "Check" button in each window of each page, system said "Window (my window name) does not fit onto page(height)". Even I create a new page and a new window in it, it still said this error when I click "Check" button in the new window.
   I have tried to enlarge or reduce the window's size, but this error still occured. But I can activate the form correctly. And there is a syntax error in the generated program:
   FORM %EV2.
    LOOP AT INTO .
    CALL FUNCTION 'SSFCOMP_TABLE_ROW_BEGIN'
    EXPORTING I_LINE_TYPE = 'LINE2'
You can see there's an error in loop statement.
Could you tell me the reason and how to solve it?
Thanks a lot!

hi
good
as you have maneioned in your error you have said that you have created your own window,but the check box as you mentioned which check box that it it is output options tab check box or in the condition tab check box.
in the general attribute select the secondary window from the dropdown box and output options tab select the page size as you need .
i hope you will get some output .
thanks

Web Service Strange problem

Hi
I have the following strange problem while calling a
web-service that is bind to a data grid on a popup container:
When I’m calling the web service using the popup
container automatic event (i.e. show, creation-completed, activate,
etc) the structure returned from the web service is an [Object
Proxy] type that needs to be decipher…
Changing the logic and calling the same web service by a user
interface action (click etc), returns an ArrayCollection Object.
The question is actually what is the difference between an
automatic and a user action?
Should there be such a difference?

Hi
Again you are trying to add an empty line and then delete it. Well what i am saying is you dont have to do the lines
complex.addRETURN(new ComplexType_BAPIRET2());
complex.addUSERLIST(new ComplexType_BAPIUSNAME());
ComplexType_BAPIUSSEXP d1 = new ComplexType_BAPIUSSEXP();
complex.addSELECTION_EXP(d1);
ComplexType_BAPIUSSRGE d2 = new ComplexType_BAPIUSSRGE();
complex.addSELECTION_RANGE(d2);
complex.removeSELECTION_EXP(d1);
complex.removeSELECTION_RANGE(d2);
input.setParameters(complex);
Just write the following code and you are good to go.
Bapi_User_Getlist_Input complex = new Bapi_User_Getlist_Input();
wdContext.nodeBapi_User_Getlist_Input().bind(complex);
complex.setMax_Rows(10);
complex.setWith_Username("X");
try
wdContext.currentBapi_User_Getlist_InputElement().modelObject().execute();
catch(Exception e)
wdComponentAPI.getMessageManager().reportException ("Exception occured "+e,true);
Hope that helps you. You dont have to pass any values to the table structures. This specific bapi does not require data to be passed to the structures and by doing so empty lines are added and that is what i was saying when i explained in my previous post. Hope that clarifies your doubt. Do let me know in case u require further clarifications.
If you are getting a error saying Return and Selection_EXP are required check the mapping.
It is enough if you just select the nodes under
   Bapi_User_List_Input
      |_Output
      |    |_Return (Model Node)
      |    |_Selection_Exp (Model Node)
      |    |_Selection_Range (Model Node)
      |    |_Userlist (Model Node)
      |    |_Rows (Model Attribute)
      |_Max_Rows (Model Attribute)
      |_With_Username (Model Attribute)
and of course select the Model Attributes MAX_ROWS and With_Username
Let me know if you require any more information

Setting session attributes at the Role level

I am running AM7.1 in Legacy mode and I am trying to create a role and assign session attributes at this role level. I followed the instructions for doing this but it does not seem to be working. I created the role and added the session service to it. I then went in an changed the attributes (Max Idle, Max Session, etc.) to the values I need for the role. I then assigned the role to a user. However when I log in as this user and look at the Active Sessions panel all of the values are still saying they are set at the defaults. It is not picking up the new values for the user. Am I missing something? Help! -Jeff

Reply i was also getting this problem in relam mode but 7.0..........but when i specify in the url?role=rolename..........i see the session info applied but i wanted it to be dyanmically applied(without specifiying the role in the url).......i have raised an SR but that is for 7.0 .........please do it for 7.1 i think you might get some response.

Session Attribute

Hi,
We have some problems with our portlet (deployed on portal 10g). We have two “applications”. One is outputting a menu with links to the other JSP that is redirecting the user.
In the first application we set a session variable that needs to be read in the other JSP. But the redirecting script can’t read the session variable (session.getAttribute always returns null).
And the funny thing is, we have an old version of these two scripts that are deployed and running on the same portal in the same OC4J (under different name) and they work properly.
We checked all the settings we could think off, but we didn’t find anything.
Regards,
Gregor

Hello Gregor,
Here i have few quick thought that hit my mind..
I am assuming you are developing JPDK portlet, right ?
Just check out two settings,
First:-
While registering the provider, on the General Properties page we first write the web provider URL. Then on the same page, under User/Session Information section, make sure that Login Frequency must be selected as Always and Required Portal user specific session information must be checked.
Click on Apply and OK.
Second:-
In the provider.xml the session attribute must be set to true.
If you have already done the above steps, and still facing issues.
please let me know, we will find some solution.
Thanks

Error in retrieving session attribute for ejb remote in clustered env

          We store EJB remote object in session and differnt clients retrieve it from sessionbefore
          making a business method call. This seems to work in most cases but sometimes
          it gives the exception attached. This happens only in a clustered environment.What
          has been observed is that if we put the remote object inside a hashtablewhich
          in-turn is stored in session retrieval from hashtable does not give thisproblem.
          Any suggestion / solution would be greatly appreciated.

Fetch a session attribute without transfer it as parameter

Hellow everyone, now I meet a greate problem:
I put a session attribute with a code (as identifier) in HttpServletRequest,
but do not know if there is any way to fetch it from request object in a none servlet/jsp class
without transfer the HttpServletRequest object? for example, should I use some context object fetch it
directly from context rather than from request object.

Hi!
If you want to fetch the session object without transfering the parameters, then you can try with the getAttributeNames() method of the HttpSession Interface.
Try it out!
If u face any problem mail me, here itself or else to my mail id : [email protected]
Regards,
dinesh
