Passing vectors

Does anyone have any examples of passing a vector from method to method?

I agree with the principle that you might need access to methods not defined in List but in this case I really don't think it's necessary. What could you use the Vector for other than a dynamic size list? Why would you need to call setSize()? By saying that the method takes a List you have documented the concept that the method does something with a list, not necessarily a Vector. It's confusing to specify a Vector in the method because it leads you to believe that it does some Vector specific stuff to it, which it most likely doesn't.
Regardless, Vector shouldn't be used because it's now a legacy class. Let's all join the 21st century and start using ArrayList :-). And don't give me the, "but Vector's synchronized and Arraylist isn't" argument.
List list = Collection.synchronizedList(new ArrayList());

Passing vectors in a JSP Page

Hi All,
Can anybody please tell me as how I can pass vectors from a page to another page and how Can I retieve the value from the next page?
Thanks,
Aarthy

I am using this code in the first page
request.getSession.setAttribute("vec",v2);In the Recipient page
Vector v5=new Vector();
v5=(Vector)request.getSession().getAttribute("vec");I am getting nullPointerException when i try to get
the size of the vector.Can anyone tell as where I am
going wrong?
Thanks,
AarthyHow did u delclare your vector v2
did u say
Vector v2 = new Vector()
session.setAttribute("vec",v2);
if you just have said
Vector v2 ;
session.setAttribute("vec",v2);
and trying to access v2.size() will throw NULL pointer exception
good luck

Passing vector of object with multiple datatype

Hi
I want to pass vector of objects to stored procedure and I am facing some problem
please suggest is it possible or I need to follow some other way.
I have one class detail with two attributes i.e int ID and string course
In main I have created 1000 objects of different ID and course and pushed back the objects to avector of detail and passed to a function my function is
void bulkdatainsert(vector<detail>rec)
stmt = conn->createStatement ("begin storeBulk(:1);end;");
     stmt->setMaxIterations(rec.size());
     stmt->setMaxParamSize(1,1024);
     setVector(stmt,1,rec,"course"); // The error coming here
The error is due to the type rec .
I want to know can we pass objects of multiple data to stored procedure through OCCI ?
If not do we need to break every attribute and make vector of corresponding attributes and pass to stored procedure?
please suggest me
Thanks

I think Custom objects are not supported directly.
Following are the normal ones which you can use
void setVector(
Statement *stmt,
unsigned int paramIndex,
const vector< T > &vect,
const string &schemaName,
const string &typeName);
Intended for use on platforms
where partial ordering of function
templates is not supported, such
as Windows NT. Multibyte
support.

Problem in passing vector from an applet to servlet

Hi,
I m facing problem in reading an object in the servlet (that i send from an applet). I have used BufferedInputStream ... The servlet reads the object but it takes about 30 seconds to do this ... If i don't use BufferedInputStream, it gives an "error reading inputstream header" ... if i use it, it take 30 seconds ... i m using netscape ent. server 4.0 ...
Servlet code is as follows :
try {
InputStream in = req.getInputStream();
inputFromApplet = new ObjectInputStream(new BufferedInputStream(in));
saveVector = (Vector)inputFromApplet.readObject();
I don't understand why it takes so long ... is there any other way ? Please help on this ... you may email me on [email protected]
Thanks in advance..

When you send a Vector through a stream, it must not only pass the Vector itself, but all the objects that the Vector refers to, all the objects that those objects refer to, and so on. Combine all this data with a slow internet connection, and passing what may seem like a small Vector could take minutes or hours.
Are you sure you're passing a very small amount of data over a fast connection?

I think the question whether you should use Vector over arrays, but rather should you use Lists over arrays. Vectors are kind of deprecated. You should be using the Collections Framework as a whole, and that means that ordered items are in java.uti.Lists, where are a kind of java.util.Collection, and a Vector is just a particular kind of List, and not necessarily even the best kind -- an ArrayList or LinkedList is often better.
The advantage of arrays over Lists is that they can hold primitive types trivially. You can only hold objects in Lists, so you can put primitive class wrapper objects in Lists, but that has its disadvantages. Apparently in JDK 1.5 there's some syntactic sugar to make this easier, but there are still other disadvantages.
The advantages of Lists over arrays are like what you mentioned -- things like resizings are automatic, there are lots of convenience methods, etc. The Collections Framework provides an abstraction of, well, collections, which is a good thing over futzing with details like with arrays, frequently.

My first problem was to write a method, smallestIndex that takes as its parameters an int array and its size. Return the smalles element in the array and its postion.

It won't pass the vector through to the method. I believe

Pass Vectors To HTML or SCript and Another Problem....HELP...PLEASE....

Hi,
I am creating a Servlet project.
I want to create screen#2 depending on what values are inputed in Screen#1.
Basically i want to Dynamically change the "Document TYpe" depending on First or last name....
The main thing is passing either a Vector or Array from screen#1 to generate "Document Type" in Screen#2.
How can i pass a Vector or array to either HTML or JavaScript...
Screen2 uses frames sets is there a better way to do this so I don't have to call two different files from one frame set file...
Any Help will be greatly Appreciated....
Thanks in advance...
Screen#1:

Passing vectors into JSP from Servlet and passing data back to Servlet

I have been building an MVC application.
It has a controller which instantiates classes and evokes methods to
populate vectors. These vectors are then passed into a JSP. This part of the application works fine.
What I am having trouble with is a new JSP I have designed; this will
display the data that is actioned by the FORM action. This is actioned
based on the Search criteria entered by the user. Based on this a further vector is populated and brought back to the JSP as a vector
and this is rendered via the TABLE tag. Again this works fine.
Against each of the rows displayed, I have a print checkbox which can be checked by the user. On checking the records they want to print, they should then hint a Print button which should go back to the Servlet and print the data. THIS IS WHERE I HAVE THE PROBLEM. On going
back to the servlet the checkbox values are not displayed, rather
the values that initially populate the JSP. How do I get these new values back into the vector and hence accessible from the Servlet.
Any help with be very much appreciated.
Chris

Thanks for this.
Just to clarify I am not using Struts.
What I am having difficulties with is the fact that:
I can't get the checked values back to the Servlet - they keep the values they have in the bean - so as part of instantiating the bean class I set the value of the item to 'off'. The user will then check
the checkbox which should presumbably set the value to 'on'. This isn't happening because the setter method of the bean is not evoked again
because I don't come into this JSP again - the Servlet has finished here
and now needs to print the records. It can't do this because as
far as it is concerned nothing has changed since it last passed through
the vector to the JSP.
Even when I do the following:
Enumeration paramNames = request.getParameterNames();
String param = null;
while (paramNames.hasMoreElements())
param=(String)paramNames.nextElement();
System.out.println("parameter " + param + " is " +
request.getParameter(param));
what comes back is the valus of 'off' as opposed to 'on'.
The other thing is that 'request.getParameterNames()' only works
with the first record in the vector, i.e. it doesn't fetch any other
records that are rendered in the <TABLE> tag.
In desperation is there anybody out there who can help me.
Thanks
Chris
I am going to assume you are using a MVC framework
like Struts or very similar (I am assuming that from
the language you are using).
When the servlet passes the vector back to the JSP
page and you render the HTML that is passed back the
client your Vector is gone. The Vector is not
available at the HTML level that is being viewed at
the browser.
When the user selects the checkboxes and submits the
page (by clicking the print button) the controller
servlet (called ActionServlet in Struts, yours maybe
called something else) forwards the request to the
appropriate JavaBean and Servlet to process the
request. Either the JavaBean has to recreate the
Vector (not recommended) or the processing Servlet can
(better). You can do this by recreating the Vector
from scratch for the HttpRequest parameters or, at the
time of the initial request, saving Vector to a
session and then updating with the data you get back
from the client (again from the HttpRequest
parameters).
Either way you have to work with
HttpRequest.getParameter().

How to pass vector array to JasperReport

I have a query looks like this... in my JasperReport. (select * from employee where employee_id = $P{Emp_ID} order by employee_id)
I already created a vector array contains a list of employee IDs from database. Now, I want to pass the array into the query to get a specific list of employees.
Similar to SQL prompt below.
SQL> select * from employee where employee_id in (1,3,4,5,22,23,45) order by employee_id.

jasontey,
I'm doing the samething here but with arrays and I'm getting ClassCastException.
Servlet1:Vector PatientInfoVector = new MdlPatient().getPatientInfo(userId,patientNumber);
int patientLength = PatientInfoVector.size();
MdlPatient[] PatientInfoArray = new MdlPatient[patientLength];
for (int i=0; i<patientLength; i++)
PatientInfoArray[i] = (MdlPatient)PatientInfoVector.elementAt(i);
session.setAttribute("patientSession",PatientInfoArray);
response.sendRedirect(response.encodeRedirectURL("/FsuSecurity/SrvSecurity"));
SrvSecurity:
MdlPatient PatientInfo = (MdlPatient)session.getAttribute("patientSession"); This is where I'm getting the ClassCastException.
int patientNumber = PatientInfo.getPatientNumber();

How to pass VECTOR to a stream

i need to pass this vertor to the server side..
but i don't know what method to use.
CODE
VECTOR
send_to_server = new Vector();
send_to_server.add(0,input_str_name);
send_to_server.add(1,input_str_password);
I ALREADY CREATED A SOCKET AND CALLED S AND ALSO HAVE THIS CODE FOR CONNECTION.
//Create socket
Socket s = new Socket(server, port);
//input from server| bytes to char
InputStream is = s.getInputStream();
//to allows us to use more function | dis.readDouble
DataInputStream dis = new DataInputStream(is);
//send output to server |char to bytes
OutputStream os = s.getOutputStream();
//to allow us to use more function
DataOutputStream dos = new DataOutputStream(os);
s.close();
PLEASE HELP ME TO SEND THE VERTOR WITH THE PROPER METHODS OR FUNCTION...

hi,how are you
why not try to use ObjectInputStream and ObjectOutputStream,thus all will become simply
for example:
ObjectOutputStream writeSocket = new ObjectOutputStream(connectedSocket.getOutputStream());/* connectedSocket=socket connected */
writeSocket.writeObject(Your Vector Object);

I think this is similar to the last post but anyways maybe somebody can help us both out bontyh.....I am getting an error saying undefined variable or class when i try to access a Vector which was returned in a class.
Anyways anyone got any ideas?

Maybe if you give some more information...

Vector in session

Hi
I am passing vector in session between two jsp's
In the first jsp I have
session.setAttribute("serialnumber_Vect",serialno_Vect);
In the recieving jsp I have the following
Vector serial_Vect = (Vector)session.getAttribute("serialnumber_Vect");
But i am not able to see the values in the receiving jsp
what is the problem
Thanks
Arn

did u set your scope to session?

Getting the value from a hashtable

Hi all,
Can I get the value from a Hashtable by passing vector.toString() , in the get method?
I am storing the key value pair using the key as vector.toString() as the key and a string value. When i am using the get method by passing vector.toString() I am getting an exception
found : Object
required : String.
Thanks and regards
Tanmoy

Exception? "found: X required: Y" sounds more like a compiler error to me.
You need to post the lines of code that cause the error so we can see what's going on.

Creating a new class

Hi all,
I am new to Java programming and trying to figure out some issues with a class
This is the problem I am trying to solve
1. I am trying to parse a xml and represent it in a JTable
2. I have parsed the xml and stored it in vector of vector formate [rows, columns]
3. Now I need to take input from the vector and fill in the table model
//dataVector is a Vector of Vector
CarrierData cData = (CarrierData) dataVector.elementAt(rowIn);
above statement is one I have issue with, I am not sure how the 'CarrirData' class should be
This is the undestanding I have:
1. as dataVector is a vector of vector, when we do elementAt(row) this would return another vector
2. CarrierData should be a class that has a constructor that has pass Vector as a parameter?
3. Based on the vector elements when we do get of each item this can be returned as column value for the table!
Can some one help me if the approach I am going with is a right way?

all,
I was not able to post my ans earlier today Thanks all for the reply
Here is the mistake what I did, as I mentioned I was trying the following
1. Parse the xml file and store it in a Vector of Vector
2. Read the Vector and add it to a CustomObjectTable model
3. and use this new tableModel to populate the JTable
The mistake I did was storing the data in Vector of Vector, which would work for a a normal DefaultTableModel , but as I was using a wrapper based CustomTableModel this did not work.
according to the code I had pasted
CarrierData cData = (CarrierData) dataVector.elementAt(rowIn);
dataVector is a Vector of Class that would return an Object and when I typecast to the CarrierData, you can acccess all the methods underneath the class to set the column data
So this is how I solved the issue
Parsing the xml
CarrierData rowData = new CarrierData();
if((((Element)nodes).getAttribute(CID)) != null)
rowData.setID(Integer.parseInt(((Element)nodes).getAttribute(CID)));
so the CarrierData class will look as follows
public classs CarrierData
public CarrierData()
protected int getID()
return m_id;
protected void setID(int id)
m_id = id;
protected int m_id;
