in the jsp, set the scope to request. it might help. u might also want to re-direct it to a new jsp which is a copy of the existing processLauch.jsp to avoid fiddling around with the old one. :)

hi rachna,
JSP has a default(implicit) session object...... use the getSession(true) method on the session object and then going u can either get or set attributes depending on the requirement
That was in general and now with the issue u have got..... what u can do is that the u can create session for every user who logs in and when he/she tries to login again then u can probably check for the existing session object in the JSP and perform the logic as required..... any clarifications plzzzzzzz let me know
Thanks n Regards

How to update session state from form field values without submitting page?

Hi,
I am new to Oracle APEX. I am using Oracle Apex 4.2 on Oracle 11g release 2. The problem is that when I am entering data on a form, when I enter a value in one field and move to the next field, how can I use the value of first field in the validation procedure of next field? I know that when we enter data in fields, the session state is not updated with these values until we submit the page... right... but I have seen that if there is a control of List box type, then Apex gives an option "Action When List changes" where we can choose option to update corresponding session state field with the value of list box item, without submitting the page.
Now my questions is why this option is only available for List box items? why not for other item types like Text box, Check box,... ? can someone please help me with this?
(the issue with update of session state depending on page submitting, is that we need a complete network round trip from client to server in order for it. However if we can update session state variables without submitting page, then we can avoid this network traffic).
Any help will be greatly appreciated. Thanks in advance.

Create a dynamic action on change and run a PL/SQL process there with the following code:
BEGIN
NULL;
END;Page items to submit > your item.
This will set the session state without submitting the form.
Further examples here:

How to update Row Object in JSP Page? urgent!!!

HI,
I have a JSP Page and I have used jbo:DataSource and jbo:ApplicationModuleTags.
Step 1: I have created a oracle.jbo.ViewObject view using
view = ds.getRowSet().getViewObject(); and executed query using view.executeQuery()
Step 2: I access the Row Object for this view like this
Row rs = ds.getRowSet().getCurrentRow().
Step 3: I try to set the attributes for this Row using setAttribute methods like this
rs.setAttribute("empName","James");
Step 4: Now I want to update this row. How to update this???
If i need to get a Transaction object, which object's getTransaction I should use?
Note: Please note that I haven't used <jbo:Row > tags to access my row. I simply get the Row object from view and want to update certain attributes and commit to database.
Thanks
Hari

Hi Harihara!
I think the record pointer is still before the first row, because you just executed the query.
Try one the following statements instead of 'Row rs = ds.getRowSet().getCurrentRow()':
Row rs = view.first();
or
Row rs = ds.getRowSet().first();
And don't forget to commit your changes if the master process doesn't take care of it already!
Good Luck!

br,
ChrisI am not sure what you want, but you can add properties to the session
property set in the EBCC, by adding custom properties. You should then
be able to retrieve them programmatically.

Calling Session Beans in JSP ?

Hi Folks,
I am new to EJB3, I am doing simple applicatuions.
Can any one please tell me how to call session beans in jsp page.
for example my case is.. iam entering two diffrent data, lets say user name and password in jsp page and this should go in data base thru JPA (entity beans)
Iam able to enter data from JPA in data base but if the same i have to fetch from JSP page.. iam not getting..!
I would really appretiate for your help i need it urgent...!
thanks in advance.

Not. You can, technically, but you shouldn't. JSP should be for display purposes only, containing no Java code whatsoever.
for example my case is.. iam entering two diffrent data,Wrong. You cannot possibly have "2 data", the very concept is impossible.
You can have "2 data items" which is probably what you intended to say?
lets say user name and password in jsp page and this should go in data base thru JPA (entity beans)
Iam able to enter data from JPA in data base but if the same i have to fetch from JSP page.. iam not getting..!
Same way you insert them. Of course JPA entities are distinctly different from entity beans. The very concept of entity beans no longer exists in the context of JPA, it's solely used to mean EJB 2.1 or earlier entity beans.
I would really appretiate for your help i need it urgent...!
It's not urgent.

How can I use multiple row insert or update into DB in JSP?

Hi all,
pls help for my question.
"How can I use multiple rows insert or update into DB in JSP?"
I mean I will insert or update the multiple records like grid component. All the data I enter will go into the DB.
With thanks,

That isn't true. Different SQL databases have
different capabilities and use different syntax, That's true - every database has its own quirks and extensions. No disagreement there. But they all follow ANSI SQL for CRUD operations. Since the OP said they wanted to do INSERTs and UPDATEs in batches, I assumed that ANSI SQL was sufficient.
I'd argue that it's best to use ANSI SQL as much as possible, especially if you want your JDBC code to be portable between databases.
and there are also a lot of different ways of talking to
SQL databases that are possible in JSP, from using
plain old java.sql.* in scriptlets to using the
jstlsql taglib. I've done maintenance on both, and
they are as different as night and day.Right, because you don't maintain JSP and Java classes the same way. No news there. Both java.sql and JSTL sql taglib are both based on SQL and JDBC. Same difference, except that one uses tags and the other doesn't. Both are Java JDBC code in the end.
Well, sure. As long as you only want to update rows
with the same value in column 2. I had the impression
he wanted to update a whole table. If he only meant
update all rows with the same value in a given column
with the same value, that's trivial. All updates do
that. But as far as I know there's know way to update
more than one row where the values are different.I used this as an example to demonstrate that it's possible to UPDATE more than one row at a time. If I have 1,000 rows, and each one is a separate UPDATE statement that's unique from all the others, I guess I'd have to write 1,000 UPDATE statements. It's possible to have them all either succeed or fail as a single unit of work. I'm pointing out transaction, because they weren't coming up in the discussion.
Unless you're using MySQL, for instance. I only have
experience with MySQL and M$ SQL Server, so I don't
know what PostgreSQL, Oracle, Sybase, DB2 and all the
rest are capable of, but I know for sure that MySQL
can insert multiple rows while SQL Server can't (or at
least I've never seen the syntax for doing it if it
does).Right, but this syntax seems to be specific to MySQL The moment you use it, you're locked into MySQL. There are other ways to accomplish the same thing with ANSI SQL.
Don't assume that all SQL databases are the same.
They're not, and it can really screw you up badly if
you assume you can deploy a project you've developed
with one database in an environment where you have to
use a different one. Even different versions of the
same database can have huge differences. I recommend
you get a copy of the O'Reilly book, SQL in a
Nutshell. It covers the most common DBMSes and does a
good job of pointing out the differences.Yes, I understand that.
It's funny that you're telling me not to assume that all SQL databases are the same. You're the one who's proposing that the OP use a MySQL-specific extension.
I haven't looked at the MySQL docs to find out how the syntax you're suggesting works. What if one value set INSERT succeeds and the next one fails? Does MySQL roll back the successful INSERT? Is the unit of work under the JDBC driver's control with autoCommit?
The OP is free to follow your suggestion. I'm pointing out that there are transactions for units of work and ANSI SQL ways to accomplish the same thing.

HOw to update XML file residing in DAM by component JSP in run-time?

i have made a component which reads xml file residing in DAM.
Content Author can fill some values in dialog of this component, as soon as author provide the values,i have to update these values in XML file and component reloadsby reading the updated xml file.
i am trying to achieve this by making object of XML file and giving it's path., but i ma unable to access the XML file.
Can anyone help me out to how to update XML file by component JSP in run-time?

Now the changed data must be exported back into the XML file, meaning that the content of certain elements must be updated. How can this be done with XSLT?
XSLT approach: check these online tutorial
http://www.xml.com/pub/a/2000/08/02/xslt/index.html
http://www.xml.com/pub/a/2000/06/07/transforming/index.html
ABAP approach:
for example you have the xml (original) in a string called say xml_out .
data: l_xml type ref to cl_xml_document ,
        node type ref to if_ixml_node .
create object l_xml.
call method l_xml->parse_string
exporting
    stream = xml_out.
node = l_xml->find_node(
    name   = 'IDENTITY'
   ROOT   = ROOT
l_xml->set_attribute(
    name    = 'Name'
    value   = 'Charles'
    node    = node
(the above example reads the element IDENTITY and sets attribute name/value to the same)
like wise you can add new elements starting from IDENTITY using various methods available in class CL_XML_DOCUMENT
so how do I access the XML file in order to update it?
you have already read this XML into a ABAP variable right?
Sorry couldnt understand your whole process, why do you need to read local XML file?

How to know if a session finished in jsp

Hello,
How to know if a session finished in jsp?
Help me please.
Best Regards.
Joseph

Depends. You can create a javax.servlet.http.HttpSessionListener implementation and register it in the web.xml file (I forget the syntax, though), which can notify you of sessions being created and destroyed.
Or you can create a javax.servlet.http.HttpSessionBindingListener implementation and add it to the session (setAttribute()) and it'll have it's valueUnbound method called when the session expires (or the attribute is removed, but if you don't remove it, the session invalidating will). That's a good place for session-specific clean-up.
