Pass String Array to Another JSP

Hi,
I want to pass a string array to a nother JSP. Could any one pls tell me whether this is possible in JSP,then how. If it's impossible how can i full fill my task.
Thanks,
Dumindu.

Depends on how you are navigating from one jsp to the other.
For ex: if you are using a forward
in jsp1
sthinglike
String[] strArray = new String[]{"val1","val2","val3"};
request.setAttribute("arrayatt",strArray);in jsp it can be retrieved as
String[] ret = (String[])(request.getAttribute("arrayatt"));
Hope that helps

Example of passing String Array from java to C using JNI

hi all
i searched net for passing string array from java to C but i dont get anything relevent
i have
class stu
int rollno
string name
String [] sub
i want to pass all as String array from java to C and access it C side

1. Code it as though it were being passed to another method written in java.
2. Redefine the method implementation to say "native".
3. Run jnih to generate a C ".h" file. You will see that the string array
is passed into C as a jobject, which can be cast to a JNI array.
4. Write the C code to implement the method and meet the interface
in the generated .h file.

Passing an array from one jsp page to another.

I need to pass an array from one page to another, without using the query string.
Can anyone help?
I was given one suggestion about putting the array inside a Map object, then putting the map in the session.
Is there an alternative? i am struggling to find out how to use maps properly.
Alternatively, could someone give me a pointer on how to implement this possibility?
Help needed ASAP.
Thankyou

First.jsp
String[] str = {1,2,3,4,5};
session = request.getSession(true);
session.setAttribute("str",str); //or application.setAttribute("str",str);
Second.jsp
session = request.getSession();
String str[] = (String[])session.getAttribute("str"); //or String str[] = (String[]) application.getAttribute("str");
Now you can use str[].

The name in getAttributre doesnt match the name in setAttribute.
Note "subject[0]" is a string containing 10 chars, "subject" is a string containing 7 chars.
Here is your code:
session.setAttribute("subject",subject);
String sub1=(String) session.getAttribute("subject[0]");

Sorry,
i guess i attached the wrong picture.

I read from a spreadsheet.
and analysis certain row and column, then do calculation and write the results to a new spreadsheet.
it is working fine.
but as an option. i wanted to "read all the data from the spreadsheet as the previous image" and then write those data to the same new spreadsheet file but in a different worksheet.

How to Pass String array from Java to PL/SQL and this use in CURSOR

hi,
I cant understand how to pass Array String as Input Parameter to the Procedure and this array use in Cursor for where condition like where SYMPTOM in( ** Array String **).
This array containing like (SYMPTOM ) to be returned from the java to the
pl/sql (I am not querying the database to retrieve the information).
I cannot find an example on this. I will give the PL/SQL block
create or replace procedure DISEASE_DTL<*** String Array ***> as
v_SYMPTOM number(5);
CURSOR C1 is
select distinct a.DISEASE_NAME from SYMPTOM_DISEASE_RD a
where ltrim(rtrim(a.SYMPTOM)) in ('Fever','COUGH','Headache','Rash') ------- ***** Here use this array element(like n1,n2,n3,n4,n5..) ******
group by a.DISEASE_NAME having count(a.DISEASE_NAME) > 3 ----------- ***** 3 is no of array element - 1 (i.e( n - 1))*****
order by a.DISEASE_NAME ;
begin
for C1rec IN C1 loop
select count(distinct(A.SYMPTOM)) into v_SYMPTOM from SYMPTOM_DISEASE_RD a where A.DISEASE_NAME = C1rec.DISEASE_NAME;
insert into TEMP_DISEASE_DTLS_SYMPTOM_RD
values (SL_ID_SEQ.nextval,
C1rec.DISEASE_NAME,
(4/v_SYMPTOM), --------**** 4 is no of array element (n)************
(1-(4/v_SYMPTOM)));
end loop;
commit;
end DISEASE_DTL;
Please give the proper solution and step ..
Thanking you,

I've haven't properly read through your code but here's an artificial example based on a sql collection of object types - you don't need that, you just need a type table of varchar2 rather than a type table of oracle object type:

Is there an easy way to replace individual elements in one string array from another striing array?

I have a string array with elements as follows:
   00 00 00 00 00 00 00 00
   00 00 00 00 00 00 00 00
   00 00 00 00 5E 00 00 00
   00 00 50 00 30 00 33 00
   34 00 39 00 00 00 00 00
   00 00 00 00 00 00 00 00
   00 00 00 00 00 00 00 00
The array I want to use to replace values with is:
43 4E 31 30 30 33 30 30 31 41
Where 43 goes in the 3rd row fifth position
Where 4E goes in the 3rd row seventh position
Where 31 goes in the 4th row first position
Where 30 goes in the 4th row third position
Where 30 goes in the 4th row fifth position
Where 33 goes in the 4th row seventh position
Where 30 goes in the 5th row first position
Where 30 goes in the 5th row third position
Where 31 goes in the 5th row fifth position
Where 41 goes in the 5th row seventh position
So the final array looks as follows:
   00 00 00 00 00 00 00 00
   00 00 00 00 00 00 00 00
   00 00 00 00 43 00 4E 00
   31 00 30 00 30 00 33 00
   30 00 30 00 31 00 41 00
   00 00 00 00 00 00 00 00
   00 00 00 00 00 00 00 00
Is there an easy way to replace an element of a string within an array with another element of a string within a different array?
Thank you.

Why passing string from applet to jsp doesn't work?

Hi,all:
I have a application requires applet to get client side info, then pass this "info"--string to the JSP.
Applet code:
try{
     URL url = new URL(getCodeBase(),"test.jsp?
java.version=1.2.2&java.vendor=Sun);
     URLConnection conn = url.openConnection();
     conn.setDoOutput(true);
     conn.setUseCaches(false);
     conn.setRequestProperty("Content-Type", "application/octet-stream");
     conn.connect();
} catch (Exception e) {
     System.out.println("The error is at URL:"+e.getMessage());
My jsp code is:
<%
String java_version=request.getParameter("java.version");
String java_vendor=request.getParameter("java.vendor");
%>
However, it doesn't work. Could anybody help me figure out?
Thanks in advance.
Paul

Request Jsp with
test.jsp?URLEncoder.encode("java.version")=URLEncoder.encode("java.version.value")&URLEncoder.encode("java.vendor")=
URLEncoder.encode("java.vendor.value")

Pass string array to Oracle function from Web page

Hi. I need to pass a two-dimensional array of string values to an Oracle function from an ASP.NET page. Is there an efficient way to accomplish this? I'm thinking I'll have to create a long string with special delimiters,
|12345^4.000|67890^3.670|.....
I'd parse the string on Oracle and break it into its component parts. In this example, each "record" is separated by the bar "|" and each field is separated by the up arrow "^". So each record has two fields.
Is this a good approach? Your input is much appreciated. Thanks.

In PL/SQL, it is easy enough to define a record type with two attributes and declare a store procedure that takes in an array of those parameters. I know that from Java it is possible to create and pass in such an array. I would suspect that the same is possible from .Net but I am not a competent .Net developer.

Passing String Array from Java to PL/SQL

Hi,
We are having couple of packages which have been written in PL/SQL . I would like to know how i can send arrays as input parameters from Java to any stored proc in Oracle. I am having Oracle 8i as the DB and am using Websphere RSA for deployment purposes.
please find below Java , PL/SQL code and exception
PL/SQL Code :
PACKAGE PKG_SURCHARGE
IS
TYPE commodity_key IS TABLE OF VARCHAR2(500) INDEX BY BINARY_INTEGER;
PROCEDURE RETRIEVE_CHARGES
in_Commodity_tab IN commodity_key,
IS
BEGIN
dbms_output.put_line('in_Commodity_tab(' || '0' || ') : ' || in_Commodity_tab(0) );
Java Code :
CallableStatement cstmt=null;
Connection conn=null;
try{
conn=getConnection();
System.out.println("++++++connected");
String sqlStr = "{call Pkg_Surcharge.RETRIEVE_CHARGES(?) }";
cstmt = conn.prepareCall(sqlStr );
//1.
String[] javaArray={"20081117","20081117"};

System.out.println("++++++registered-1");
Catch (Exception e){
e.printStackTrace();
Exception Occured:
java.sql.SQLException: Invalid Pattern Name <Schema Name>.commodity_key
Appreciate your help in this regard
Thanks

Avi is correct. You must create a varray or nested table instead of using a PL/SQL index-by table.
SQL> create type commodity_key as varray(#) of varchar2(500);
or
SQL> create type commodity_key as table of varchar2(500);
Use the varray if you know the number of items in the array. Otherwise, use the nested table.

I want to pass String array to Stored procedure .

ArrayDescriptor claim = ArrayDescriptor.createDescriptor("POOJA.VARCHAR_TBL" , conn);
String test[] = {"an","jk"};
ARRAY a = new ARRAY(claim,conn,test);
cstmt.setArray(noOfParms,a);
It gives class cast exception at ArrayDescriptor .. Dont know why ?
Need an urgent help ...

ArrayBinding feature is for bulk operation where a SP or SQL statement executes ArrayBindCount time in one server round trip. Each execution uses the nth element in the parameter (array) and execute the SP or SQL statement.
This is done internally in the database, and not related to the SP or SQL statement at all.
The PL/SQL Associative array support might be the feature that you're looking for.
Please take a look from our Doc on these topics for further information. Also take a look in the ODP.NET dissucssion forum's samples section.
Thanks

Passing a multidimensional array between 2 JSPs

I intend to pass a multidimensional string array from one JSP to another JSP.
I have been able to pass a single dimensional array as a hidden attribute at the first JSP and am retreiving it at the second JSP using request.getParameterValues("...").
But, request.getParameterValues("...") works fine only with one dimensional arrays..Is there a way to do something similar for 2 two dimensional array ???

You can only pass strings as parameters.
You you interpret those strings is entirely up to you.
request.getParameterValues() gets you an array of all the parameters with the same name. To have it "passed between jsps" you actually need to include them in the request parameters with each request.
You can always use session attributes to retain state at the server end. - session.getAttribute / session.setAttribute()
Or, seeing as you know you are dealing with a string, convert the array to a string, and back.
But you can't pass an actual "object" over parameters

Passing values to form bean string array from dynamic added textboxes

Hi,
I am unable to pass values to form bean string array from a jsp in which I have incorporated dynamically adding of textboxes in javascript.
I have given add/delete row option in the jsp. If there is single row, this is working fine. But after adding a row, I am not able to either do any validations on added textboxes or pass the values to the String array form bean variable.
code snippet:
var cell6 = row.insertCell(4);
var element5 = document.createElement("input");
element5.type = "text";
element5.className = "formtext1";
element5.size = "5";
element5.value = "00.00";
element5.name= "qty"; // this is a string array of the form bean.
element5.onchange=function() {checkNumeric(this);};
cell6.appendChild(element5);
<html:text styleClass="formtext1" property="qty" value="" size="5" styleId="qty" onchange="checkNumeric(this)"/></td>
form bean declaration
private String[] qty; Please help.

Shivanand,
There's no need to post that much code when you could create a very short test case that demonstrates only the problem you are having.
You're using &NAME. notation on something that isn't a page or application item. You can't reference PL/SQL variables that way (or any other way) outside the PL/SQL scope. For your situation, you could create a page item named P55_DOCID and assign it a value in the PL/SQL process (:P55_DOCID := DOCID;), then reference &P55_DOCID. in HTML areas like the success message.

Thank you jverd, I was able to get that to work for me.
I have another basic question about arrarys now. In all of the arrary examples I have seen, the array is populated all at once using a for statement like in my program.
userData = new Person[50];
for (int i = 0; i < userData.length; i++) In my program though, I want it to only fill the first array parameter and then go up to the main menu. If the user chooses to add another account, the next spot in the array will be used. Can someone point me in the right direction for doing this?
