Javascript is not the same as Java. Try here: [http://www.webdeveloper.com].
Asking for code without showing any effort from your side is not so smart. Not here and also not at other coding forums. This way you only show how lazy and dumb you are. Rather ask technical questions, you will likely get better help sooner. If you really need someone else to develop for you, better try here: [http://www.rentacoder.com] or [http://www.freelancers.net]. Or if you want help for free, then try to [ask questions the smart way|http://www.catb.org/~esr/faqs/smart-questions.html].

How to create two level dynamic list using JSP , Java Script and Oracle
I am new in JSP. And i am facing problem in creating two level dynamic list using JSP ,Java Script where the listdata will come from Oracle 10g express edition database. Is there any easy way in JSP that is available on in ASP.NET.
Plz response with details.1) Learn JDBC API [http://java.sun.com/docs/books/tutorial/jdbc/index.html].
2) Create DAO class which contains JDBC code and do all SQL queries and returns or takes ID's or DTO objects.
3) Learn Servlet API [http://java.sun.com/javaee/5/docs/tutorial/doc/].
4) Create Servlet class which calls the DAO class, gets the list of DTO's as result, puts it as a request attribute and forwards the request to a JSP page.
5) Learn JSP and JSTL [http://java.sun.com/javaee/5/docs/tutorial/doc/]. Also learn HTML if you even don't know it.
6) Create JSP page which uses the JSTL c:forEach tag to access the list of DTO's and iterate over it and prints a HTML list out.
You don't need Javascript for this. -
Servlet with no dynamic code inside jsp pages
Hello,
I saw that a servlet is created even if there is no dynamic code inside jsp pages (scriplets & tags). Is it possible to avoid it on bea side ? (I am using portal 8).
By the way, do you know if is it possible to define apache in order to avoid to send to bea the jsp which have no dynamic code inside ?
thank you !JSP's always generate a servlet on all web containers. Apache/Tomcat is no
different. If you have static content, make it an HTML page.

Hi folks,
Im new to JSP and have been trying to figure out how to populate a listbox using JSP code.
I was hoping to get names from a database and add these names to the listbox.
Any help or suggestions would be greatly appreciated.
Thanks in Advance..The FormattedDataSet can easily do this with a couple lines of code. Check out the java docs and live demo with sample code at http://www.fdsapi.com

How do i format elements in a jsp dynamically in a jsp.
For ex
<td width=100% colspan=18>
<%= titleName %>
</td>Instead of specifying colspan as 18, i want it to automatically adjust according to the length of the word (titleName).
Thank YouUse EL.
colspan=${someDynamicValue}And replace that scriptlet by EL. Writing raw Java code in JSP files is a bad practice. -

Display of dynamic data in Listbox in jsp usin Struts
Hi,
I am trying to display a List in a jsp in Struts.
I have written a Action form and am populating a Arraylist in a DAO(java class file).
ArrayList.add(rs.getString(1),rs.getSTring(2));
But I do not know how to display the arraylist in JSP using the struts tag libraries.
Please let me know how this can be done.
Thanks in advance.

reply meThis is a little hard to follow and want to make sure I understand:
You can pass the value from page1 to page2. But when you submit on page2 to another page, the value is null?
My first recommendation is: Pull all HTML code out of scriptlets that is using out.println.
But to answer your question, you don't have the hidden fields in the <FORM> tag. They need to be places in the form tag in order for the form to pass the values when you submit. -
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. -
grrrrr............ok so I'm kinda new to this, and just a little frustrated. I'm gonna ramble here, so any time I sound like I don't know what I'm talking about it 's because I don't..correct me. I want to include a bean in a jsp which will buil d a dynamic select box on the fly. That is, connect to an LDAP db and place each value returned in the query in a select box. Now, I can compile and run the bean in my IDE and watch the output in the console. It's correct because I see "<select><option value = hall>hall....</select>". In the buildSelectBox() method I'm using System.out.println to display each line of my select box (is that right?). Now, when I copy the .class file over to the server I was initially getting an error because the bean wasn't found. I resolved that by properly compiling the bean in a package. Problem is that if I call the bean.buildSelect() method in the .jsp nothing comes back. The page is left blank. What in the world is that about? Can someone push me toward a tutorial that can push me in the right direction or sumthin? Why am I having so much trouble with this? Should I be building the select on the jsp?
regards,
matHi!
If i understand you correctly :-) you are doing not very right things. I don't want it to seem like I'm going to teach you, but:
The Bean that has buildSelect() method is not a bean at all. Usualy Beans contain getter/setters and accumulate data. If you want to build html code dynamicaly then you should use servlets(Which is not very flexible in your situation, I think), not JSPs. And if you are using JSPs then you have to make Tag which will do this everything.
Other way is to use Struts framework which is very good and flexible for building web applications - it has it's own tags for many cases. You can make loops in JSPs, use beans and all that stuff.
Guys will correct me if I missed something.
Good luck -
I have a web application that allows for text to be inserted dynamically into its pages via a content managment system.
Within this text, we have a requirement to be able to put some custom tags. The problem with this is that because the text is inserted into the Jsp at runtime, this text is obviously never compiled and thus, the custom tags never get executed.
Does anyone know of any way to compile this text at runtime, through accessing the Jsp compiler, or through the use of a tag ?Yeah, the text is inserted using a custom tag :
<cms:insert id="1234" />
And the inserted text is just html snippets, but there could be custom tags inside it, like <form:input> tags. These tags don't get executed. I was hoping to be able to be able to do something like invoking the jsp compiler on this text, perhaps inside the code for the <cms:insert> tag handler. -

We need some help regarding an unusual problem we are facing in our web application.
The background:-
We have a web page (JSP) for updating (adding, modifying, deleting) data from a single table. This page has been designed in such a way that when ever it is invoked, it displays content of the entire table on the page. Also there is a facility of filtering this content. The entire table content is displayed in a dynamic table without paging. There is one java script which is used to manage the scrolling of this table (300 rows at a time). Please not that it is just scrolling that is controlled by the Java Script, that is the entire table is displayed in a specific area with vertical scroll. Each row in this table has a radio button associated with it which is used to select a particular row for modifying it. User can select a single row at a time.
The problem:-
This page was working fine, until the number of rows in the table were under 70,000 records. Currently there are more than 72,000 records and the page doesn�t get displayed at all. It is not giving timeout error and also it is not going in to �Not Responding� state. It is simply showing a blank result page without the result table. Initially we thought that because we are fetching so much data in one go this would have been happening. But this problem arises only when we access this page from PC having Windows-XP operating system. If we access this page through a PC having Windows 2003 Server OS then it displays the entire table in a normal fashion.
We are in the process of redesigning the page, but still want to know why this is happening. It will be a great help if anybody can give any pointer on this issue. And also what should be a better option of displaying such a huge table for modification of rows.
Thanks and Regards,
Jagdish.Thanks a lot masoodmjan.
Lets assume that this problem is due to huge data being desplayed at once. Now if I decide to provide pagination to browse this entire recordset, which now has grown to 90000+ records, how many rows should I desplay on 1 page? Is there any thumb rule to decide this number?
Just now I tried with 10,000 records per page & it took more than 25minutes to display single page. :( -

I want to change the where clause dynamically.Our objective is to make the map in a generic way so that if there is a change in where clause (i.e. adding more conditions in where clause) i dont have to change the map.I can change the values(if used, say emp_no=20) however i'm facing problem changing the whole condition i.e. even the column name.
Thx
