How to add an if statement in jsp?
Hi all,
I have a displayTag table and wonder how to have a condition on the following code:
<display:column title="Accept?">
<html:multibox property="select" value = "<%=bean.toString() %>" />
</display:column>Basically, I would like to have this code (checkBox) appear only if a bean property is true (otherwise don't show it)
if (bean.userApprove)
// don't show checkBox
else
//show the checkBoxthanks for any pointers
<%
if (bean.userApprove)
%>
// don't show checkBox
<%
else
%>
<input type=checkbox name=chk value=chk />
//show the checkBox
<%
%>

Hi there,
As far as know, SAP allows to add new EBS format in ff_5.

Currently SAP shows MUTICASH, SWIFT94O something like that.

The procedure is
CREATE OR REPLACE PROCEDURE usersubscription_procd (vuserid in number, vnewsletterid IN VARCHAR2)
AS
I NUMBER;
J NUMBER;
VAL VARCHAR2(100);
BEGIN
I := 1;
J := 1;
WHILE INSTR(vnewsletterid,',',I) != 0 LOOP
VAL := SUBSTR(vnewsletterid,I,INSTR(vnewsletterid,',',I)-J);
I := INSTR(vnewsletterid,',',I)+1;
J := I;
INSERT INTO usersubscription (usersubcriptionid,userid,newsletterid)
VALUES (usersubscription_seq.nextval,vuserid,VAL);
END LOOP;
VAL := SUBSTR(vnewsletterid,I,LENGTH(vnewsletterid));
INSERT INTO usersubscription (usersubcriptionid,userid,newsletterid)
VALUES (usersubscription_seq.nextval,vuserid,VAL);

How do you do Switch statement in JSP
using the HTML tags!
using the HTML tags!HTML has no switch capabilities.
If you mean using JSTL, then you can use the <c:choose>, <c:when> and <c:otherwise> tags to behave like an if else structure:
<c:choose>
<c:when test="${var == 1}">
//something
</c:when>
<c:when test="${var == 2}">
//something
</c:when>
<c:otherwise>
//something
</c:otherwise>
</c:choose> -
How to add the update statement in this procedure?
I have one table usersubscription (userid,newsletterid,deleted)
I got one string from user e.g. ('1,2,3') and userid = 14
I wrote proceduer that will insert this records in to usersubscription table;
userid newsletterid deleted
14 1 n
14 2 n
14 3 n
default value of deleted column is 'n'.
my procedure is as follows;
CREATE OR REPLACE PROCEDURE usersubscription_procd1 (vuserid in number, vnewsletterid IN VARCHAR2)
AS
I NUMBER;
J NUMBER;
VAL VARCHAR2(100);
BEGIN
I := 1;
J := 1;
WHILE INSTR(vnewsletterid,',',I) != 0 LOOP
VAL := SUBSTR(vnewsletterid,I,INSTR(vnewsletterid,',',I)-J);
I := INSTR(vnewsletterid,',',I)+1;
J := I;
INSERT INTO usersubscription (usersubcriptionid,userid,newsletterid)
VALUES (usersubscription_seq.nextval,vuserid,VAL);
END LOOP;
VAL := SUBSTR(vnewsletterid,I,LENGTH(vnewsletterid));
INSERT INTO usersubscription (usersubcriptionid,userid,newsletterid)
VALUES (usersubscription_seq.nextval,vuserid,VAL);
END;
Now one requirement is that when new string comes for same userid e.g.('1,4,5') userid = 14
then the deleted column for 1 and 2 newsletterid changes to 'y';
please tell me the solution.
Prathamesh.Hi,
Before your loop, you can make something else like :
SQL> select * from test;
USERID NEWSLETTERID D
14 1 n
14 2 n
14 3 n
SQL> update test
2 set deleted = 'y'
3 where instr('1,4,5',newsletterid,1) = 0
4 and userid = 14;
2 ligne(s) mise(s) à jour.
SQL> select * from test;
USERID NEWSLETTERID D
14 1 n
14 2 y
14 3 y
SQL> HTH,

Does anyone know how to create an INSERT statement with JSP using
variables??
I can do the insert if I code the values of the variables in the statement,
but when I try to use variables to do the insert it tries to insert the
variable name and not the value of the variable into the table.
Thanks,

How can we add a control on our .jsp webpage for uploading several image fi
How can we add a control on our .jsp webpage for uploading several image files as done in gmail attachment, Where a Remove button also appears if we wanna remove the particular attachment.
The SCOM Management Server is in Domain A. I've tried it already and it has failed.
So just to clarify the method I used was to go to Administration>Security>User Roles. Then New User Role>Read-Only Operator. In the Create User Role Wizard I then gave the User Role a name, Clicked "Add" under User Role Members.
Then the Select Users or Groups window pops up and I changed the Locations from Domain A to Domain B and searched for the user, which it's able to find, then clicked "OK" to add it to the User Role members which it does just fine. On
the next page which is Group Scope I checked the one group I want this account to have access to and then click next. This brings me to Dashboards and Views where I click the radio button for "Only the dashboards and views selected in each tab are
approved" and chose the folder of dashboards I want this account to access and then click next. This brings me to the Summary and I click "Create". At this point it thinks for a moment then closes out the wizard but the new Read-Only
Operator does not appear. I then look in Event Viewer and see the Event I pasted above.
Am I doing something wrong here? Any guidance on how to get around this issue would be much appreciated.
Thanks,

How to add a frame dynamically in a jsp page.
Hai all,
In my application, in a particular jsp page i had the 3 links namely add.edit and delete. When click on add button, it is pointing to another jsp page where i can enter user details. But what i want now is when i click add button, the form in which we fill the user details should be added to the current page itself dynamically i.e., it should not go to another page when i click add button and that form should be displayed in the current page in a new frame dynamically.
The same should happen when i click n edit or delete options. everything should be diaplayed in the same page in different frames.
Can anyone suggest me about how to add a frame dynamically.You create a frameset with two frames. One frame you give 100% of the rows and run the JSP in this frame. The other frame you give 0% of the row so that it is hidden. In the JSP you use a JavaScript funtion to submit the form. This function will call the parent frameset to reset the row values to 50%/50% which will make the bottom frame visible and then submit the form request with the bottom frame as teh target.
It is not so much as creating frames as using JavaScript to hide and display frames. -
