Hello, there.
I haven't worked with Oracle database, but I've used taglibs almost the same way with mySQL, so if you are using the correct JDBC driver and Oracle requires no special SQL notation, it looks really strange to me, because you are doing everything correctly.
What I would suggest is to leave data source definition without any variable, i.e. default for the whole JSP page. You can do it this way:
<sql:setDataSource
 driver="oracle.jdbc.OracleDriver"
 url="jdbc:oracle:thin:@RioDev:1521:transco"
 user="kim"
 password="kim"/>In our query you don't need datasource variable either
<sql:query var="result">
 SELECT * FROM kim.ALARM
</sql:query>ForEach looping you seem to do correctly. So, if your driver, username and password are correct, you should pick up the data without problems. Certainly if the table has data in it... ;)

9iAS JSP/Tag Library Help needed

Info: We have 9iAS 9.0.2.0.0 running on Sun Solaris (Sparc). I have been to Sun class for JSP/Servlets (SL-314) and have an Iterator custom tag that works fine in Tomcat 4.0. I am compiling on a Windows NT machine using Ant and JDK 1.3. I then deploy using Oracle Enterprise Manager (web interface to 9iAS) and use the Deploy WAR option. The only examples I can find that came with 9iAS use JSP 1.1 Taglib code and they work. Am I missing something, or does 9iAS (9.0.2.0.0) not fully support JSP 1.2 / Servlet 2.3, specifically the 1.2 tag library API?
Any help would be appreciated...
Code Snippets from failing JSP:
<%@ taglib uri="hr/taglib" prefix="hr" %>
<hr:iterator id="empdata" listName="employeeList">
<li><jsp:getProperty name="empdata" property="name"/> (<jsp:getProperty name="empdata" property="depth"/>)</li>
</hr:iterator>

Sorry techie_sudhanshu .. i was away for the month with no internet access and just got back... here's an example :
<display:table name="CUSTOMERS" pagesize="10" id="customer" sort="list" defaultsort="3" requestURI="/customer.do?submit=Search" class="model">
 <display:setProperty name="paging.banner.placement" value="both"/>
 <display:setProperty name="paging.banner.some_items_found" value=""/>

 <display:setProperty name="paging.banner.all_items_found" value=""/>
 <display:setProperty name="paging.banner.no_items_found" value=""/>
 <display:setProperty name="paging.banner.onepage" value=""/>
 <display:setProperty name="basic.msg.empty_list"><center>No Record(s) was found.</center></display:setProperty>
 <display:column title="Name" sortable="false"><c:out value="${customer.name}"/></display:column>
 <display:column title="Address" sortable="false"><c:out value="${customer.address}"/></display:column>
</display:table>The line where `<display:setProperty name="paging.banner.placement" value="both"/>` was specify solves your problem. By setting it to BOTH it will appear above and bottom of the paging table.

Standard Tag library

Hi All
Could anybody let me know what are all standard tag libraries is
being used for JSP Development in Jdeveloper 3.2.3 environment
apart from the default one.
I founnd couple of them on internet, but its difficult to decide
which one to use. Can some body provide me the url's where I can
download the trial versions of them
Thanks!
Arvind

Try the Apache Jkarta project tag libraries. They're free and
quite extensive. Kudos to Apache for all the fine work this
group does.

Tag Library Help

Hello,
I have just started to learn about Tag libraries and it's not been the most pleasant experience. Anyways, I did manage to figure out most of the basics of Tag Libraries, but am still unable to understand the use of script variables. I saw an example in the tutorial by Sun, where they used a bean called "book" and I came up with a similar example myself. But in my TEI class the value for type coomes up as null and i had defined a type in my jsp page with my bean tag. Also, all the attributes that come up in my TEI class are my attributes and not my script variables. Is there something wrong in what i am doing?
I am using tomcat 4.1.10 as my server. and JSP 1.2.
This is my JSP page now.
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<%@page import="com.petris.data.User" %>
<HTML>
<HEAD>
<TITLE> This is a sample page to test the Hello World Tag Library </TITLE>
<%@ taglib uri="HelloWorld.tld" prefix="hello" %>
</HEAD>
<BODY>
<hello:sayHello userName="Dummy User" age="27">
<% String dummy; %>
</hello:sayHello>
<jsp:getProperty name="user" property="name" />
 
The user age is <jsp:getProperty name="user" property="age" />
</BODY>
</HTML>
And this is my TEI class
package com.petris.tags;
import javax.servlet.jsp.*;
import javax.servlet.jsp.tagext.*;
import java.io.*;
import java.util.Enumeration;
public class HelloWorldTEI extends TagExtraInfo
 public VariableInfo[] getVariableInfo(TagData data)
 Enumeration listOfAttributes = data.getAttributes();
 StringBuffer listOfTags = new StringBuffer();
 for(int i = 0; listOfAttributes.hasMoreElements(); i++)
 Object currentObject = listOfAttributes.nextElement();
 listOfTags.append(currentObject.toString() + ",");
 System.out.println(currentObject.toString());
 String type = data.getAttributeString("type");
 System.out.println("*********************");
 System.out.println("TYPE = " + type);
 System.out.println("*********************");
 if (null == type)
 type = "java.lang.Object";
 return new VariableInfo[]
 new VariableInfo("user",
 "User",
 true,
 VariableInfo.AT_BEGIN)

i think i have it figured out. If we want to use the TagExtraInfo class, then we must supply the values to the tag using attributes. Values such as id and type must also be supplied as attributes. Which automatically means that we must supply the bean type getters and setters for these attributes as well. Well this is how i have been able to get it to work. If there is some other way (other than using the variable tag in the TLD), please do let me know. Thought i would post this for others as a future reference.

I simply user, i.e. I want to place its database on virtual host (Tomcat+(JSP-JSTL)+MySQL).
There is idea how can resolve this problem
Thank you in advance ;)

For all how have similar problem.
Decision instead of these ways
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %>
<%@ taglib prefix="sql" uri="http://java.sun.com/jstl/sql" %>
it is necessary to indicate these
<%@ taglib prefix="sql" uri="http://java.sun.com/jsp/jstl/sql" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

Standard Tags

I am trying to find out the Que position of a person in waiting Q. These are the steps I am following:
1. getting the record set
<sql:query var="myRecordset" dataSource="$myDataBase " >
SELECT myName FROM WaitingList
ORDER BY registerationDate
</sql:query>
2. Iterating through record set
<c:forEach var="row" items="$myRecordset.rows">
<c:if test="$row.get('myName') == '$varName'">
.... I want to display the row number
</c:if>
</c:forEach>
Now the problem is:
1. I want to declare varName at run time. I am not able to do so my using the standard JSP methods like <%= .. %>. How is it done in tags. Please help me.
2. How do you find the row number? I went through the tag documentation, but I could locate any method.
Please Help me

<c:if test="$row.get('myName') == '$varName'">
1. I want to declare varName at run time. varName already is a runtime variable, but setting it directly is probably what's throwing you.
I've run into the same problem. The standard tag library generates some really obscure Java.
You can set the value with <c:set var="varName" value="whatever" />, but then how you you set the
value of value?
Until we figure out the right way, one workaround is to use scriptlets for the conditionals:
String myVarName = whateverIWantItToBe;
String myMyName = <c:out value="${row.myName}" />;
<% if (myMyName == myVarName) { %>
[ conditional code here ]
<% } %>
2. How do you find the row number? <c:out value="${thisRow.count}"/>

Tag Library Compile Warning

Why does the weblogic jsp compiler wine about this standard tag library
 descriptor DTD?
 <?xml version="1.0" encoding="ISO-8859-1" ?>
 <!DOCTYPE taglib PUBLIC "-//Sun Microsystems, Inc.//DTD JSP Tag Library

 Have yet to see a TLD that does not use precisely this string and yet
 weblogic whines constantly about it.


I figured it out. Under the Configuration/TagLibraries,
create a CrossTagAttr folder and stick a .vtm file in it. In the
.vtm file, use the <crosstag_attributes> tag and its
children. See Configuration/TagLibraries/CrossTagAttr/Spry/Spry.vtm
for an example.

SQL in JSP - do I use JAVA code in % ... % or SQL Tag Library ??

I have a small web app that makes needs to make about 12 SQL queries in a JSP and am trying to figure out what is the best way to do this
I had initially coded this using plain JAVA code in the JSP as follows :-
<%
Connection conn = null;
Statement st = null;
ResultSet rs = null;
try {
st = conn.createStatement();
rs = st.executeQuery("select .........");
%>
But then I came across the SQL Tag Library in an article and wonder if this is more efficient code?
If so does anyone have a pointer to a good intro to these tags as they look complicated (I only am doing queries on the SQL database, no inserts or updates)

Sometimes you've gotta do what you've gotta do.
My rule is "no scriptlets".
If you MUST access a database from a JSP, the only right way to do it is to use JSTL <sql> tags.

Problem with sql;query tag! Please help ...

Dear all,
I have the following SQL statement submitted by a sql;query tag:
<c:out value='${namestring}'/> // <-- namestring is printed out as ABC-% here.
<sql:query var="resultset">
SELECT sales
FROM SALESTABLE
WHERE name LIKE <c:out value='${namestring}'/> //<-- appearently namestring is not ABC-% anymore!!!
</sql:query>
Everything is fine except the satement "WHERE name LIKE ?". The namestring passed in is supposed to be in the form 'ABC-%'. It indeed prints out as 'ABC-%' before the <sql:query/> tag.
Appearnetly, when it is passed to the statement "WHERE name LIKE ?", it becomes something else because it returns no data.
Note that when I hardcode 'ABC-%' to the WHERE statement, however, I do get a lot of data back.
I also tried to to use <sql:param/> tag to tackle it:
<sql:query var="resultset">
SELECT sales
FROM SALESTABLE
WHERE name LIKE ?
<sql:param value='${namestring}' />
</sql:query>
But still got no data. Is '%" considered as special characters that needs to be treated in a special way? What else do I need to do in order to pass in 'ABC-%' to the statement???
By the way, is there a way to print out the generated SQL statement to see how all the variables are evaluated?
Any help or suggestions will be highly appreciated. Thanks.
Robert.

Try to escape the special character '%' using '\%'.

Jsf-1_0-pfd-spec.pdf - 9.5 Standard HTML RenderKit Tag Library

I am somewhat confused by section 9.5 in jsf-1_0-pfd-spec.pdf.
It ends with
"Each action included in the Standard HTML RenderKit Tag Library is documented
in a subsection below, with the following outline for each action:"
I however seem to miss these subsections.
Am I interpreting something wrong or is there stuff missing?
Thanks,

The description of Std HTML Renderkit (8.5 ) as well as the Std HTML tag library will be updated by the next release. In the mean time, please refer to the TLD. Sorry for the confusion if any.

Need help on Flex JSP tag library

I am new to Flex and currently developing portlets where I
need to integrate Flex into JSP pages. According to various
documents from Adobe and other online discussions, this can be done
with Flex JSP tag library. It appears that the taglib used to be a
separate package that you could download but no longer available (I
was only able to find a few broken links). Instead, the library is
now part of the LiveCycle DS product according to Adobe. However, I
have downloaded LiveCycle DS and couldn't find the necessary taglib
in the package. Your help will be highly appreciated.

I'm trying to do the same thing you are. Its mentioned that
the library is part of LifeCycle DS but I couldn't find it in there
either.
Here's a site I found where you can download
FlexModule_j2ee.zip It includes some instructions too.

Help with Pager Tag Library

I am developing a photo website with the JSP Pager Tag Library (http://jsptags.com/tags/navigation/pager/index.jsp). I have installed it and am using it successfully.
I have one question.
I have a page called view_fotos.jsp. This page has the pager tag to display the photos in a series of pages. view_fotos.jsp can accept a variety of parameters.
For example:
view_fotos.jsp?groupnum=10
view_fotos.jsp?groupnum=10&user=john
view_fotos.jsp?user=john&mode=view
Now, I would like to add the QueryString to all the indexed page links.
i.e. The page links should become...
view_fotos.jsp?groupnum=10&pager.offset=0
view_fotos.jsp?groupnum=10&pager.offset=6
view_fotos.jsp?groupnum=10&pager.offset=12
or
view_fotos.jsp?groupnum=10&user=john&pager.offset=0
view_fotos.jsp?groupnum=10&user=john&pager.offset=6
view_fotos.jsp?groupnum=10&user=john&pager.offset=12
depending on the request's QueryString. Can anyone please let me know how can I accomplish that?
Thanks for your kind help!
Regards,
Joe

Take a look at the docs on the pg:param tag. Those parameters will make it on the end of your URL. You might also have to export the offset variable in the pg:pager tag so that you can use it later with <%=offset%> but I think if you set the max items per page part of pg:pager to 6, it will do the offset stuff for you. The docs for the pager tag library should have more info though. That's found at http://jsptags.com/tags/navigation/pager/index.jsp along with the download.

Connection Pooling and JSP Custom Tag Library - is code (inside) the best way/correc?

Hi, can anyone advise as to whether my tag library code (based
on Apache Jakarta Project) will actually achieve connection
pooling functionality across my entire JSP based application? I

may exist multiple times, hence rendering my conection pooling
attempt useless.

Can you please help me the reason why this problem is happening and how to fix this ?
This problem doexn't happen consistently. This occurs once in a while.
I tried to increase Login delay Seconds parameter in the Connection Pool to 15 sec. It didn't help me much.
Thanks for your help !!!

Announce: JSTL (Standard Tags) + Struts (MVC) live web Demo (open source)

If you are starting a Java Web, you should use MVC and Standard tags,
          this "kit" is a sample of "best" (at least good) practices.
          It is MVC (Struts/Tiles)+JSTL XSLT DAO (Open Source Data Access Object
          w/ SQL) + DB CRUD (Create update delete and SQL DLL scripts)+ J2EE
          Security ( to make Tomcat run like Apache )
          It is KISS (you'll see how simple and how very standard) , good
          practices Free Open Source Framework to develop any web app, with the
          aim of being 80% of any app, but done as simple as possible and easy to
          teach. Again, everything is standard and simple. And it is the fastest,
          most efficient way to develop maintainable code I know of.
          Samples include CMS (Authorize content, XSLT, CMS Comments, sinkable,
          single sign on, etc.), Issue tracking, + more coming.
          Please download and install and see if you want to attend. Details:
          http://basicportal.sourceforge.net
          I use it to teach Struts + JSTL public and private classes. I epically
          teach WHY you should want to do something in a certain way, not just how.
          To attend and see "best practices"
          http://www.basebeans.com/webEx.jsp
          The seminar requires you know servlets, jsp, SQL, JDBC, and at least
          some MVC. (a plus is if you have already deployed and MVC web app in the
          past) Oh...it is $10.00 ( but free to baseBeans clients and/or apache.org
          committers.)
          To keep in touch on this join "MVC-Programmers" mail list at
          http://www.netbean.net/mailman/listinfo/mvc-programmers
          To keep in touch with open source projects go to
          http://news.netbean.net/cgi-bin/webnews.cgi
          Future plans include more docs, Dream weaver support, mail client, RSS
          feeds, BLOG, Shopping Cart Store, etc. etc.
          Did I say everything is standard and as simple as possible?

Struts tag library instead of JSTL

My developers here are not very well versed with JSTL .
Is it advisable to use the Struts tag library instead of JSTL.

For JSTL you need two jar files in your web-inf/lib directory.
standard.jar
jstl.jar
You only mentioned standard.jar - make sure the other is there as well.
There are also some libraries requried. I think they were included with JDK1.4, but am not entirely certain.
Check out the requirements on this page:
http://jakarta.apache.org/taglibs/doc/standard-1.0-doc/standard-1.0/GettingStarted.html
Particularly those related to JAXP.
I am think EOFException might be a trouble with parsing the c.tld file in the standard.jar
Hope this helps,
