Pagination using JSP Presentations.

Hi,
I have implemented a search function in my JSP presentation. The search shows an array of bpm objects in a table and I want to put them in pages with a pagination like google does. I've tried with a taglib, importing the jar in my library and modifying the web.xml of the workspace. But it doesn´t work because I don't know How to use the bpm instances inside scriplets. How can I implement this functionality, is that possible?. I know that this kind of jsp works different than in a normal web application because we use the jsp fuego taglibrary.
Thanks for your help,
Guillermo

About the fuego tags and scriplets, for example, I have created a group[] of BPMObjects, then I call my BPM Object method by an invoke instruction in my jsp. This method has the query and constructs the group of BPMObjects. My problem is when I try to manage this array with Java inside an Scriplet, because the pager taglib requires it.
I understand how to use the rownum for pagination, my doubt in this case are the parameters that I have to send to BPM from the links of my jsp. ( First _1_ _2_ _3_ _4_ _5_ Last) . Do you have an example or documentation about how to send this parameters?
You mencioned DynamicSQL, I used it to implement the SQL script. About this, I have decide what is better to implement when I call a SELECT. I know that the DynamicSQL improves performance because it sends the statement and runs in the database server. Another option is to use a "Parametric Query" but I don't know if the performance is the same than a DynamicSQL. On the other hand, I'm implementing Stored procedures and call them from bpm to improve performance, leaving the execution of the SQL Statement to the database server. It is successful when the stored procedure is an insert or update, but when the procedure is for SELECT, I don't know how to receive the cursor from the stored procedure and stores the values inside my BPM objects group[]. Do you have any idea about this?
Thanks Mark,
Guillermo

What the "use JSP presentation" check box does?

Can someone tell me what the "use JSP presentation" check box does? (can't find any documentation)
When I set "Implementation type" to "BPM Object Interactive Call' if a check "use JSP presentation" instead of "Use BPM Object Presentation" and I enter a JSP name can I cause the process to start a JSP ?

Hello,
The option is intended to use a JSP instead of a form for a BPM Object interactive call. This means that you have to prepare your custom JSP, add a special tag library provided by Fuego and "mark" your html tags deciding which of them will become the attributes for the instance of your BPM Object.
Whitin the page you can also call some methods of your objects.
Finally you can post back the data and automatically update your object in the process. There is no much documentation and it's even quite old. Take a look here: [http://download.oracle.com/docs/cd/E13154_01/bpm/docs65/taglib/index.html]
The JSP will be shown as a normal interactive activity popup window. You can customize it as you like, even adding some client side script.

Dynamic Tree Creation using JSP, Struts framework

I urgently require tips/information/code snippet for creating a Dynamic Tree structure.
Tree is the hierarchical folder structure that we see in windows operating system.
Dynamic tree in the sense that all nodes shall be populated from database & a radio button shall be present at each node that can be selected & submitted to form.
Tree should be done using JSP (& if required Javascript).
I am using Struts framework .

Writing Html Content into PDF using JSP

Dear All,
I am using JSP to generate Employee payslip dynamically. Presently i am diplaying payslip as on-screen display.
Here i want to give option "Save as PDF". I am able to create PDF file using IText Libraries. i want to integrate HTML code into the PDF file.
Writing HTML Content (using HTML Tags) into PDF.

Well it is a difficult ask and i believe we are trying to re-invent the wheel
Just to make my life simple i could have choosen either sample API given below to serve my cause
1).[http://xmlgraphics.apache.org/fop/] (Apache FOP one can simply write an XSL template of their and then substitute the values from respective DTO's by using XSL - XML transformations and can generate content in different formats which includes PDF aswell)
2).[http://jasperforge.org/plugins/project/project_home.php?group_id=102] (Just design a simple report template using iReport and create a jrxml files and write a small code snipett such that you can pass few details at the runtime and can export the report in different formats which includes PDF aswell)
3).[http://www.object-refinery.com/jfreereport/] (Is much similar to what jasper offers in order to compile these you can either use pentaho product IDE or BEA/Oracle Actuate report tools)
You can simply try searching for different examples for getting more help on using the respective API's
Hope that helps :)

How can WLS use JSP pages in a Web Application witth just a JRE [Web Application, WAR, JSP, weblogic.jsp.pageCheckSeconds and JRE]

 How can WLS use JSP pages in a Web Application (either a .war file or a war directory structure) without a java compiler?
 I suspect either the JSP specification is flawed (i.e. it doesn't take account of servers using just a JRE), or BEA's implementation is broken.
 Production servers do not have a JDK installed. They only have a JRE. Therfore a java compiler is not present on the machine that the Web Application is deployed onto.
 On the development machine, when the server is requested to load the JSP it creates a tmpwar directory within the Web Application directory structure. This is then included in the resultant .war file thus:
 D:\war>jar -tf gmi.war
 META-INF/
 META-INF/MANIFEST.MF
 gmiService.jsp
 WEB-INF/
 WEB-INF/classes/
 WEB-INF/classes/com/
 WEB-INF/classes/com/bt/
 WEB-INF/classes/com/bt/gmi/
 WEB-INF/classes/com/bt/gmi/gmiService.class
 WEB-INF/getList.xsl
 WEB-INF/getListByConnection.xsl
 WEB-INF/getListByDistrict.xsl
 WEB-INF/getListByDistrictConnection.xsl
 WEB-INF/lib/
 WEB-INF/source/
 WEB-INF/source/build.bat
 WEB-INF/source/gmiService.java
 WEB-INF/web.xml
 WEB-INF/weblogic.xml
 tmpwar/
 tmpwar/jsp_servlet/
 tmpwar/jsp_servlet/_gmiservice.class
 tmpwar/jsp_servlet/_gmiservice.java
 When deployed on the production server with the web.xml file set to use the following values (note XML stripped):
 weblogic.jsp.pageCheckSeconds
 -1
 weblogic.jsp.precompile
 false
 weblogic.jsp.compileCommand
 javac
 weblogic.jsp.verbose
 true
 weblogic.jsp.packagePrefix
 jsp_servlet
 weblogic.jsp.keepgenerated
 false
 And in the weblogic.properties file:
 weblogic.httpd.webApp.gmi=war/gmi
 I've also tried with the .war file, but that insists on creating another tmpwar directory outside of the .war file.
 Then, although I have set pageCheckSeconds to -1 (don't check and don't recompile) ter production server still attempts to recompile the JSP's:

The default Java compiler from sun lives in the tools.jar that comes with
 the JDK. Just add that to your set of JARs which are deployed in production
 and you should be fine. No need to install the full JDK - just make the
 tools.jar available to WebLogic.

Problem with database using JSP

Hi
i am developing one application which uses JSP ..to connect to the database..at present i am using MS-access for the data storage...
I have two pages in one page there is a form where user fills all the details and once submit the information based on the form has to fetch the data from the backend...i have a problem ..if i hard code the corresponding column name in the JSP page it is getting all the data but if i get it from request.getParameter("")( which i am supposed to be from the form) i am getting no records..
take a look at the code below and let me know...
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
java.sql.Connection conn= java.sql.DriverManager.getConnection("jdbc:odbc:asiafinity");
java.sql.Statement stmt=conn.createStatement();
/* If i print a value from the previous pages its showing but its not going to the database with query statement..
// String str1=request.getParameter("religion");
// System.out.println(str1);
/* If i hardcode the corresponding columun data its querrying the data
String str1="hindu";
String sqlquery="select * from userprofile where religion='"+str1+"'";
System.out.println(str1);
java.sql.ResultSet cols=stmt.executeQuery(sqlquery);
while(cols.next()){
String gen=cols.getString("gender");
String age=cols.getString("age");
String rel=cols.getString("religion");
String cul=cols.getString("culture");
String loc=cols.getString("location");
String pro=cols.getString("profession");
String uname=cols.getString("username"); %>

Please help me out..i know this is an simple problem
Thanks & Regards

try it and tell me what happens

Using JSP scriplets in the JSF tags

Hi,
I haven't done that much JSP development using various tag libraries prior to looking at JSF, hence this very basic question:
I am declaring and manipulating Java variables in my JSP. Is there a way to access those in my JSF tags? It seems that something like:
<%
String myString="MyLabel";
%>
<h:view>
<h:outputText id="myID" value="<%=myString%>" />
</h:view>
blows up in the JSF processor.
I am porting some stuff to JSF and hence do not use backing beans in all cases.
Any suggestions/ideas/pointers are greatly appreciated.
Thanks in advance,
Vadim.

JSF action element attributes take JSF EL expressions, not Java expressions. A JSF EL expression has access to objects in one of request, session or application scope only, not to scripting variables. One way to get your example to work is by putting the String in one of these scopes within the scriptlet, e.g.:
<%
String myString="MyLabel";
request.setAttribute("myString", myString);
%>
<h:view>
<h:outputText id="myID" value="#{myString}" />
</h:view>But, if you're porting a JSP-based application to JSF, I strongly recommend that you move all scriptlet code into beans; otherwise it's kind of pointless to migrate to JSF. The strength of JSF is its separation of UI layout and application logic.
Even though JSP happens to be one way to wire up a JSF view with JSF components, JSF has very little to do with JSP. You need to understand the basic JSF component model, event-driven development, and use JavaBeans to really gain any benefits. Don't be fooled into believing that JSF is "just a new JSP tag library" by the support for JSP as the default presentation layer; it's far more than that, and I personally believe that using JSP as the presentation layer makes using JSF a lot harder than it should be. In fact, most of the issues posted in this forum are issues with the JSP layer, not with the core JSF components or the infrastructure classes.

When should we use JSP?

Hello!
I have a little general question about JSP because now I'm going to embark upon web development (till today I have been developing native applications). Is JSP used in really big web applications by professionals? I mean, something much bigger than simple forums, rather whole social networkings portals etc? And can JSP fully replace PHP (in practise) in a project or these technologies are rather mixed? Can you give me some examples of web portals developed in JSP? I hesitate between JSP or PHP. I'm familiar with Java and have no experience with PHP. I hope you will help me in making a right decision ;-).
Kind regards,
John.

There are a few big choices for Web development:
- PHP - long the first choice of teenagers and amateurs, recently with version 5 and frameworks like Symfony, it is maturing.
- ASP - the Microsoft solution, easy to use, very little structure. A favorite with small business. Recently ASP.Net has provided objects.
- CGI - used with Perl, this is the grand-daddy of them all, still used, cheap and cheerful, but it doesn't scale well.
- JEE - Java Enterprise, provides more choices than you can shake a stick at, used by well to do amateurs, students, and big corporations. Hosting for JEE is much more expensive than for the first three, but it is much more powerful.
---- JSP - the favorite presentation system for Java servlets. This is a Java version of ASP, by itself it provides little structure
---- Velocity, Webmacro and Freemarker - template engines for Java, often run faster than JSP
---- Struts - Apache's MVC solution, uses JSP or Velocity for presentation
---- Spring MVC - the new system on the block, a big improvement over Struts, still uses JSP and Velocity for presentation
---- JSF - Sun's answer to MVC, a component based system like ASP.Net. Provides rapid development at the cost of being tied to forms and tables. Uses a strange version of JSP for presentation. Don't get me started on <verbatim>.

Pagination using pager tag library (logical groupings)

I'm currently trying to achieve pagination using the pager tag library provided by jsptags.com.
Instead of the usual breaking up the records into a fix number to be displayed per page, I need to display these records by grouping per page. E.g., my records are grouped by countries, so each group varies in size.
I would not be accessing the database directly from the JSP page, in fact, the JSP page will get a collection of the objects that I want to display per page.
Has anyone done anything like this before? Would appreciate very much if you could share with me how you implement this.
Thanks!

Hi there,
I am wondering if you found the solution for your question with paging in JSP. if so i will really appreciate if you can let me know, how you did it. I am using Pager tag lib from JSPTags as well and i used collection object to iterate through. But i have some problems. I am wondeinf if you can help me with this
Thanks
Vik

Implemented pagination using JSTL !

Hi,
I have implemented pagination using JSTL and uploaded the code at the following website
http://www.planet-source-code.com/vb/scripts/ShowCode.asp?txtCodeId=4718&lngWId=2Please send feedback on improving the code if any to [email protected]
It can be used for doing Pagination using JSTL.
Change the query as required in pagination.jsp
Rows to be displayed per page can be changed by changing the variable rowsPerPage in printResult.jsp.

Congrats! Atleast you are posting a solution.

Using jsp:param

hi,
i am new to java and jsp programming and i am trying to use jsp:param nested in my
jsp:forward statement.
if i specify a value in jsp:param my page would display properly. however when i passed a variable in my jsp:param i get the error:
Generated servlet error:
[javac] Compiling 1 source file
C:\Program Files\Apache Group\Tomcat 4.1\work\Standalone\localhost\star\jsp\Meeting_CreateMinutes_jsp.java:135: cannot resolve symbol
symbol : method encode (long)
location: class java.net.URLEncoder
pageContext.forward("Meeting_ActionItems.jsp" + "?" + "docno=" + java.net.URLEncoder.encode( carno ) + "&" + "formmode=" + "Add");
^
1 error
this is the snippet in my jsp page that (i suspect) caused the error:
<% long carno = newcar.getDocno(); %>
<jsp:forward page="Meeting_ActionItems.jsp">
<jsp:param name="docno" value="<%= carno %>"/>
<jsp:param name="formmode" value="Add"/>
</jsp:forward>
my question is : does jsp:param do not accept variables as values?
thanks in advance.
best regards,
noynoy

<% long carno = newcar.getDocno(); %>Change this part as
<% String carno = ""+newcar.getDocno(); %>

Facelet to crare web app, instead of using JSP; JSF1.2 spec in WebSphere6.1

Novice to JSF and Facelet. But, I had been using Struts since its inception.
I am required to use IBM's WebSphere Application Server 6.1 that comes with Servlet 2.4 and JSP 2.0. WebSphere 6.1 App Server limits me to using JSF 1.1. This is because, JSF 1.2 requires Servlet 2.5 and JSP 2.1, that is a part of WebSphere App Server 7.0; not a part of WebSphere 6.1.
Somebody suggested that it will be possible to use JSF 1.2 in WebSphere 6.1, if I were using Facelet, instead of JSP.
I am not eager to use JSF 1.1 and may have to forego JSF; unless and until I can use JSF 1.2.
The hold-up is that I cannot use JSF 1.2 spec in WebSphere 6.1. Is there is any way to use JSF 1.2 in WebSphere 6.1? Can I create an entire application using Facelet (instead of JSP) that will let me use JSF 1.2 spec in WebSphere 6.1? If so, how?
Here are my questions, especially because I am not very familiar with JSF and Facelet technology:
1. Can I use JSF 1.2 specification in WebSphere 6.1, if I were using facelet (as opposed to JSP) as my view technology?
2. Will it be possible to create an entire web app with facelt, instead o fusing any JSP at all? If so, how? Does it mean that all the GUI screens will only use facelet and no JSP at all?
3. Please explain how I can write a complex web app with 100s of screens using only facelet, instead of using JSP.
4. Please provide pointer on how JSF and facelet differ, or what are their demarcations boundaries.
Any comment and pointer will be greatly appreciated.

How can I connect to SQL server database thru local network by using JSP?

I'm currently doing a project by using JSP..And I need to display record from the SQL Server database in our school's local network. May I know how can I do that? How can I write the code so that I can able to access the SQL Server databsase Throught school's network by using JSP? Please tell me step by step how can I do that. I'm using Tomcat 4.1 as Web Server. And I had J2SE and J2EE installed in my computer.

first you have to establish a ODBC DSN on your computer,
that connects to the database...you can do that from your control pannel.
i assume that the TOMCAT server is residing on your computer....(if the webserver is in other computer then you would have to create a System DSN on the data sources ODBC option in the settings>control pannel of that machine)
then you can use that DSN name to connect to the data base from the class file....for further assistance on how to create the class that access the tutorials in sun site.

How to get the values of an Array using JSP Tags

Hey guys,
I need some help. I've splited a String using
fn:split(String, delim) where String = "1,2,3,4" and delim is ,
This method returns an Array of splited Strings. how do i get the values from this array using jsp tags. I don't wanna put java code to achive that.
Any help would be highly appreciated
Thanks

The JSTL forEach tag.
In fact if all you want to do is iterate over the comma separated list, the forEach tag supports that without having to use the split function.
<c:set var="list" value="1,2,3,4"/>
<c:forEach var="num" items="${list}">
<c:out value="${num}"/>
</c:forEach>The c:forTokens method will let you do this with delimiters other than a comma, but the forEach tag works well just with the comma-delimited string.

Mantosh,
Have you seen this developer zone article which details accessing Citadel Data using COM+ and ADO?
http://zone.ni.com/devzone/conceptd.nsf/webmain/725A6C3843F13C8786256EA600633724#6
Also, this KB article provides more detail on how to access Citadel data using SQL commands and I think will help answer your question:
