Grid defining in jsp

i have to make a grid of 50 * 50 ....and the cells should be defined in such a manner that i can call them individually (something like
[j]).
I dont know if i can use arrays to form the grid and output it in the form of a table.
Please suggest.

Try to use a two dimension array:
private String[][] strArray;
strArray = new String[50][50];
Loop through the array to form a table.

Variables defined in JSP include files.

hi..
i was wondering how to access the variable defined in a JSP include file from the page where it is included.

If you are thinking of scriptlets, then you would do it in the same manner that you would access variables local to your jsp. A word of caution - jsp pre-compilation may not work.
A neater solution would be store it as an attribute in 'page' scope.
cheers,

How do i place a grid into my JSP page

Hi All
I have a requirement to place the result set from a query to be placed into a grid like structure onto my JSP page, If anyone has done such a thing please help me with this, a good code sample would be better.
Thanks

A very basic one assuming the resultset rs is already populated....
<table border=1>
<%
while(rs.next())
%>
<tr>
<td><%=rs.getString(1)%></td>
<td><%=rs.getString(2)%></td>
</tr>

How to call a function defined in a JSP file into a servlet?

Hi
I have defined a JSP file with some functions in it. I am including this JSP file into other JSP files so that these functions can be used. Now is there soe way, that I can include this file in a servlet as well and use the defined functions in the servlet as well.
Thanks and Regards
Vikram

I assume you have a function with OUT arguments because you need to return at least two distinct things from this function? The functions return value and this OUT argument, too. Right? For the sake of argument, let's say that you're trying to return a VARCHAR2 value and a NUMBER value from this function.
Assuming that you cannot just wrap your existing function with a function that does not have OUT arguments, the first idea that pops to mind is to create an Oracle8 type that looks like:
CREATE TYPE MYREC AS OBJECT (V VARCHAR2(80), N NUMBER);Then you could rewrite your function to return an instance of this MYREC type instead of having one return value and one OUT parameter.
Then create a BC4J domain for this Oracle8 type (which will mimic its nested structure), and then you can just select the value straight-away in your view object.
I just tried this idea with 9.0.2 production and it works.
The Domain you create will have getV() and getN() accessors on it so you can get at the nested values in the MyRec domain "record" structure.
The other way would involve building a programmatic view object that sources the data for your VO programmatically. If I think of anything else I'll post something here.

I want to delete a user-defined preset Perspective Grid Preset.
How can I do this?

• There is no Delete option in the Grid Preset Options dialog box.
• Simply selecting my custom Grid and then hitting Delete on my keyboard does not work either.
What am I missing?
Please advise.

Data Grid on JSP Application...

Someone knows where i can get a good data grid (free) for JSP applications.

yes there is, almost anything is possible in a web application so probably a data grid too.
Might be nice idea to first give information about what you udnerstand under a datagrid before asking information on it.

Data Grid in JSP

Hi guys
I need to create a Data Grid on a JSP. It has to display data retrieved from database. I should be able to select a row and delete it from database.. I think I can manage the database stuff... But how dow I create the grid?
Any suggestion? Links?
Do help!
Thanx a ton!

Let your backend return a list of data.
Put the list on the request (request.setAttribute...).
Use jstl tag like
<c:forEach items="${myList}" var="myRow">
<c:out value="${myRow.firstname}"/>
<c:out value="${myRow.lastname}"/>
</c:forEach>

How To Retrieve an Object's Value Defined Using c:set ... Tag?

I have the value of a variable defined in JSP#1 (JSP#1 is not a form) using JSTL tag:
<c:set var="id" value="${articleForm.article}" scope="session"/>Now, I have an object 'id' in the session scope. The object 'id' and all the information, which are defined in JSP#1, are forwarded to JSP#2.
JSP#2 is a form. But, the 'id' is not used in JSP#2.
JSP#2 has a submit button and then, a servlet takes over the control after that button is clicked. All the text fields in JSP#2 together with the object 'id' are forwarded to this servlet.
I have two questions:
1. I should put this object 'id' in a request scope or a session scope? Currently, it is in a session scope.
2. How to retrieve the value of this object 'id' in this servlet? (I do not want to print the value out. I want to retrieve the value and store it in a database.)
int articleID = Integer.parseInt( session.getAttribute( "id" ) ); or, it should be retrieved in another way?

I'm not sure you understand the concept of a session object.
Java objects stay on the server. There is no transmission between the web browser and the client.
The scope just sets how long the server "remembers" that variable.
request scope - only lasts one request. Once a web page is returned to the client, the server forgets all request variables.
session scope - lasts for one user - across multiple requests/web pages.
1. I should put this object 'id' in a request scope or a session scope? Currently, it is in a session scope.From your description, you appear to have it right - your object should be in session scope.
2. How to retrieve the value of this object 'id' in this servlet? (I do not want to print the value out. I want to retrieve the value and store it in a database.)If articleForm.article is an String then that looks the right way to access it.
You might have to do it like this:
int articleID = Integer.parseInt( (String)session.getAttribute("id"));
The Integer.parseInt method takes a String as a parameter - while session.getAttribute() returns an Object.
This code will work if the object stored in the session is a String.
The object stored in the session is ${articleForm.article} What type does articletForm.getArticle() return? That is the type you need to cast it to when retrieving it from the session.

How do I setup in wls 6.1 a jsp file that has a different extension (not *.jsp)

I have a jsp file with extension *.abc. The browser is showing the files as text instead of sending it to be processed as a jsp file.
          I have the following settings in the web.xml but it is not picking it up.
          <servlet-mapping>
          <servlet-name>
          jsp
          </servlet-name>
          <url-pattern>
          *.abc
          </url-pattern>
          </servlet-mapping>


This is kind of a hack and not officially supported, but you might try...
          <servlet>
          <servlet-name>ABC</servlet-name>
          <servlet-class>weblogic.servlet.JSPServlet</servlet-class>
          <init-param>
          <param-name>compileCommand</param-name>
          <param-value>javac</param-value>
          </init-param>
          <init-param>
          <param-name>workingDir</param-name>
          <param-value>WEB-INF/classes</param-value>
          </init-param>
          </servlet>
          Since this isn't the default JSPServlet registration, it doesn't pick up the
          default JSPServlet init arguments, so after some experimentation I figured
          out that you have to at least define these two. Others that you may want to
          configure are...
          defaultFileName
          compileCommand
          compilerClass
          compileFlags
          workingDir
          verbose
          keepgenerated
          precompileContinue
          pageCheckSeconds
          encoding
          packagePrefix
          superclass
          noTryBlocks
          compilerSupportsEncoding
          These are all defined as jsp-descriptor args in the weblogic.xml file, but
          you can equally use them as servlet-args for your custom JSP registration
          Good luck,
          Alex
          P.S.
          Why don't you want to use jsp files anyway?

What's the difference between jsp and jsf?

who can tell me what's the difference between jsp and jsf?
I'm puzzled when I found some of the technology in jsp is so similar to the ones in jsp( javaserver page)

Hi,
Find the difference between JSP and JSF
1. A developer has more control with JSP, but (should) get easier development with JSF
2. Event handling is done differently in JSP (HTTP) and JSF (Java)
3. The UI is designed differently (or should be at least) with JSP (markup) and JSF (components).
4. The end product should also be defined differently - JSP page versus a JSF application.
Is this the only thing that is need to make a decision for either or? Probably not. There are other pieces that need to be taken in account when deciding which technology to use - tools support, enough components, type of application etc.... At this point there are not enough JSF components (although there are some interesting projects underway - Ajaxfaces, Myfaces, ADF Faces, and WebChart 3d) and enterprise tools support is still limited to a few tools vendor. Looking at our ADF Faces components they are currently available as early access (not production) and demands for these components are stacking up, literally, outside my office doorstep. Although I would love to make them production - now! - it is not a viable solution since we are still checking features and fixing critical bugs.
All this combined - not enough enterprise level components in production, lacking tools support etc... - leave customers in a vacuum where the decision is either to continue with JSP, since it is mature and has a wide developer base, or move forward with JSF not sure if the support, or the developers will be there. This is particularly sensitive to customers that need to get started now and be production by summer.
If you are in this vacuum here are some key points promoting JSF:
1. Fundamental unit is the Component
2. Built in event and state management
3. Component sets can be provided by any vendor
4. Closer to ASP.Net or Swing development
5. Choice of UI technology
6. Scale up (rich clients)
7. Scale down (mobile devices)
8. Built into J2EE containers in J2EE 5.0 (tentative)

Ergent problem with the jsp file access in tomcat. HELP...

I use tomcat as my server, I have one JSP file located in :
webapps\abc\war\WEB-INF\jsp\index.jsp
You see my project name is abc, I want to access the index.jsp file, I define another jsp file in the path: webapps\abc callled outside.jsp. I want to use outside.jsp to invoke the index.jsp.
Inside outside.jsp it is :
<html>
<head>
<title>index</title>
</head>
<body>
<%@ include file="war/WEB-INF/jsp/index.jsp" %/>
</body>
</html>
When I open the browser, and access, http://localhost:8080/abc/outside.jsp , the content of index.jsp was shown as expect. But, all the link pages of the index.jsp can not shown (PS: the link pages is located in the same path as index.jsp, they are all jsp files). I guess the problem may be that the <%@ include file="war/WEB-INF/jsp/index.jsp" %/> inside outside.jsp include the index.jsp as a static file. Is there any method to make all the link pages of index.jsp can be shown when call from outside.jsp???HELP

I don't know why your links can't be shown, but I can tell you that your suspect:
I guess the problem may be that the <%@ include file="war/WEB-INF/jsp/index.jsp" %/> inside outside.jsp include the index.jsp as a static file.is wrong, because included jsp is dynamic, not static.

New to JSP-How to run a .jsp file

I Have just begin to learn JSP. I downloaded the JSP developer kit from java.sun.com. However I dont know how to proceed. I have seen references to'the container'. what is it and how do I start it? and the same for the server which I have in the form a batch file. How do I configure the environment? Are there any prerequisites to using this kit wrt software? Please do help me, since I am absolutely clueless
Regards,
Sweta

Hi Sweta,
Please use any editor like eclipse or netbeans or you create one jsp page(assumes you know jsp).
and then create two folders web-inf inside which create classes and lib folder and web.xml is created, and meta-inf inside which context.xml is created. And use tomcat container to deploy.
Apache tomcat is container which would receive the client request from browser that will route to servlet/jsp.
whereas Apache webserver is different it provides the request to container if it exists then we can replace localhost:8080 by user defined.
JSP is nothing but Dynamic web page creator which embed java program in html.
JSPinit initializes and while running converts to servlet and will be processed according to the java code embed and display as per the html tags.
But you should use struts framework why it is constructed upon MVC architecture and purely object oriented.
So struts is nothing but the execution calls are drived by configuration xml files.
If anything you need to know in details, pls msg me to [email protected]
Thanking you
