You can store them in a session only if the objects in the array are serializable.

Can any body tell me How to store string array in a array

YesNot quite sure what question you're answering but here's how to copy an array.// given a String[] strArr
// pre Java 6
String[] newStrArr = new String[strArr.length];
System.arrayCopy(strArr, 0, newStrArr, 0, strArr.length);
// post Java 6
String[] newStrArr = Arrays.copyOf(strArr, strArr.length);Edit:
Or in fact use clone() as mark pointed out.

How to store forms fields into the session ?

Hi All,
I have to store forms fields into the session.
I have four forms (htm forms) in four jsps and there are total 25 fields.
I am inserting all the fields into the database at once while user submit the last form.
I want to use session to store forms fields.
So please anybody tell me how to do that.
Is the following code correct to store the forms fields into
the sesstion........
// creating a session
HttpSession session=request.getSession(true);
// retrieving form fields
String name=request.getParameter("customer_name");
String business=request.getParameter("business");
String address=request.getParameter("address");
and so on....
// store form fields into the session
session.setAttribute("name",name);
session.setAttribute("business",business);
session.setAttribute("address",address);
and so on....
and later on get the value as:
session.getAttribute("name");
session.getAttribute("business");
session.getAttribute("address");
and so on....
OR
is there another way to store form fields into the session.
Please guide and reply with coding.....
Please answer and help.
Thanks
Amitindia

I don't mean to be an *** but I have no desire to help someone so unwilling to think >>and do. Go through some of these tutorial, do the examples in each and you will be far >>better equipped to ask questions:
http://www.google.co.za/search?hl=en&q=%2Bjsp+%2Bjavabean+%2Btutorial&b >>tnG=Google+Search&meta=
I was just asking that if I use the following
<jsp:useBean id="cart" scope="session" class="session.Carts" />
<jsp:setProperty name="cart" property="address" value="myaddress" />
</jsp:useBean>then will I be able to acheive my aim as I have to store form fields into the session and later retreive while user submit the last form.
Please read my question that I have posted.
Am I using the right way................or which is the best way to store form fields into the session and later retrieve them.
please reply
Thanks

How to store 2C array to a singl binary file

Hi
I have to store multiple waveforms output that is each 1D array to a single binary file. how do i do this.
i can store 1D array to binary file and retrieve it by reading the binary file and plotting the waveform. but i am not able to store 2D array to the single file. how do store many 1D array in one binary file,
Thank you. Hema

(We would also need to know your LabVIEW version. If you have a very old version, things would be quite different.)
As Smercurio_fc already mentioned, the option to "prepend array size" would make things much easier here, because then you would read it as a single 2D array.
Here's how that would look like. This is probably the recommended solution, just for simplicity reasons.
Not prepending the size is more useful if you write the data in increments, but later want to read it as one.

I have problem how to store the array?

for(i=0;i<empRec.length;i++)
          if(empRec.getCategory()=='F'||empRec[i].getCategory()=='H')
               if(empRec[i].getCategory()=='F')
               Movie interesting[]=new Movie[2];
               interesting[i].setCategory('F');
               System.out.println("Category:"+interesting[i].getCategory());
has a exception like this Exception in thread "main" java.lang.NullPointerException
        at Movie_video.main(Movie_video.java:146)
this is my part of the coding... i want ask how to Separate out the movie numbers of all the movies in the Fiction and Horror categories and store them in an array ?interesting?.
Edited by: williamku87 on Mar 31, 2008 12:05 AM

It seems the problem is situated in the line +interesting.setCategory('F');+
You instantiated the array, but not the object within the array. A possible solution could be:
for(i=0;i<empRec.length;i++)
          if(empRec.getCategory()=='F'||empRec[i].getCategory()=='H')
               if(empRec=new Movie[2];
interesting[i] = new Movie();
               interesting[i].setCategory('F');
               System.out.println("Category:"+interesting[i].getCategory());
}But very unusual to add only one object to an array of 2. What are you aiming for using the array +interesting+?

How to store array of data into a single row of table ,using any of Stmts

HI Friends,
Based on my requirements ,i have retrived a set of data from a XXX.jsp page using a request.getParameter() and stored into single dimenssional array . Now i am paassing that array to JAVA class to store a into some table .
In JSP page users can add text boxes dynamically based on his intrest then those attributes will store in table .it means table attributes are not conatant , it table attributes may change at any time when user adds any textboxs or any fields on JSP page ....thats my module ..
Now i wanted to store all array of data into Table in a single row .......thats is my requirements .
How can we use prepareStatement and Statement to store array of results intoo table row ...on each iteration i wanted to store array of results into table atributes ..It means entire array of results should to into table row at time .....coule any one write sytax ,how we do this...
could any one suggest me stps that i can impliment ......?....please reply ASAP

Well ..you code can be works for constant number of attributes in table .oopss here my requirement is table attributes not fixed ,we cant put constant number of place holder(? ) in a statement ,because those are not fixed ,
Let me explain here :
i am doing in that way only. As i mentioned you Table attributes are not constant .It may very if users add any fields dynamically on JSP page .If users have option to add any text box on Jsp page ,then that attribute will store in table as a attribute .
Now i amable fetching the all dyamic form data and stored in a Result Array below ...in this iteration all form result data are from jsp page as suggestion form ,it should stored in table in single row on corrsponding attribtes ......next time when users fills FROM ,then those data i am fetching and storing in a Result Array as below and need to store in corrsponding table attributes in a single row ....
for(int i=0;i<result.length;i++)
               System.out.println(result);
               pst3=connection.prepareStatement("insert into *emprecord* values(?)");
               if(!result[i].equals(""))
                    System.out.println(result[i]);
                         pst3.setString(1,result[i]);
                         pst3.executeUpdate();
Thnks in advance ....let me know the the way we can store dynamic form data into dyanamic table ...

How to clear the variable value in session store?

I'll try to build form for search. There are LOV and
search button on form. When user don't select anything then push
search button, I'd like the report to show query everything. I
mean the report will show like condition where id like '%'.
And I send variable between form to report by using session
store.
I select nothing in LOV but value that return by LOV is
not null. It's in stead of old value of LOV.
Please tell me.. How to clear the variable value in
session store? I'd like to set it to null. If you have greater
way to do like this, please tell me.
Thank you.

Please suggest on this..
Thanks.

How to store logical operator in an array in java

how to store logical operator in an array in java.
Array should not be String type if i pass an element of that array it should be considered as logical operator

my exact requirment is like this, i need some logic
to convert string like this "2 Equals 3 AND 4 greater
than 7" to condition like this
2 == 3 && 4 >7 which i can pass to if
condition.So you want to create an expression parser?
No need for something as ugly as what you think you need, a simple nested conditional will do it for just the few logical operations.

How to store jsp session data of different user in util.hashmap

how to store jsp session data of different user in java.util.hashmap
and access the data of all user on the server side
The same example is given in professional jsp but its not working.
I can use getIds() of httpsessioncontext but it's depricated

Hi
I'm trying to make an example.
With the following codes you can get the date from the session.
request.getSession().getAttribute("sessionname")
To store it in a hashmap you could do it like this ->
Hashmap hm = new Hashmap();
hm.put(Object key, request.getSession().getAttribute("sessionname"));
I hope you understand it if not just write it!

How to store values in session variables for use later

I am trying to read user input from a form, lookup some values from a database,
store the combined data into session to retrieve later in the subsequent pages
in a pageflow application. Could someone guide me as to how exactly to do this?
The documentation doesn't seem to be of much help.
Thanks,
Krishna K

Krishna,
     If you will be using the data within the course of the same page flow
or nested page flows then you should store the data in the page flow
itself. Simply declaring variables in the .jpf will do this. The page
flow is stored in the session for you and it is deleted when the user
exits the page flow. This is good because it keeps down session size.
     If you have data that you want to use across page flows then you will
need to store in the session or globalApp.
     Here is a link to "Using Data Binding in Page Flows" it has an example
of storing data into the session and it goes into the pros and cons of
using each data binding scope.

Help, how would I store an array of objects ?

im doing a java project on creating a music database, i need to store an array of cd objects, each entry in the array will be a single object for a cd.
The objects are: Artist, Album, No of tracks
could sum1 point me in d right direction, thanks

This is the wrong forum. Please ask again in the [new to java forum|http://forum.java.sun.com/forum.jspa?forumID=54] .
Assuming you want to store them on disk, you can either use a database (java technologies for this is JDBC and JPA ) or write them to a file using the java technologies Serialization or Beans Persistence.

Why we cant store asiciative array in DB

hi,
plz provide me vaild reason for below query. its a complex question for me as i tried a lot to find suitable answer in net also but not satisfied.
1- why we cant store asiciative array in datbase?and we can store netted table in database how?

>

From oracle reference manual.
>
Because associative arrays are intended for temporary data rather than storing persistent data, you cannot use them with SQL statements such as INSERT and SELECT INTO. You can make them persistent for the life of a database session by declaring the type in a package and assigning the values in a package body.
>
It cannot be made to persist in the db because it's designed in that fashion as mentioned above.
