Two if condition in JSTL

can I use and in if statement in JSTL, I f I want to change the following code to JSTL , what should I do
if (!(Tassistant.equals("on"))&& (!TassistantStart.equals("dd/mm/yyyy"))&& (!TassistantUntill.equals("dd/mm/yyyy")))
do I have to use ? can I use and to connection then I don't need that much close </c:if>
<c:if test="${found.tassistant!='on'}"> }<c:if test="${found.tassistant!='dd/mm/yyyy'}"> </c:if> </c:if>
Thnak you!

You can just use the same operators in EL.
And in the future, please choose forum carefully. Posting a very simple question at a wrong forum doesn't let you overcome as smart.

Example web.xml for JSTL?

I need to find an example web.xml file that shows where thet tablib statements for JSTL go and what they look like in a web.xml file. I was looking at an article I found through Google that pointed to Javasoft doc on this subject but the link didn't work, and anyway, I prefer examples to specifications. I haven't found a good example yet. Can someone point me to one or post one? I need both contents of the taglib statements and a clear picture of exactly where in the web.xml file they go. I think the statements are:
<taglib>
    <taglib-uri>http://java.sun.com/jstl/fmt</taglib-uri>
    <taglib-location>/WEB-INF/fmt.tld</taglib-location>
</taglib>
<taglib>
    <taglib-uri>http://java.sun.com/jstl/core</taglib-uri>
    <taglib-location>/WEB-INF/c.tld</taglib-location>
</taglib>
<taglib>
    <taglib-uri>http://java.sun.com/jstl/sql</taglib-uri>
    <taglib-location>/WEB-INF/sql.tld</taglib-location>
</taglib>
<taglib>
    <taglib-uri>http://java.sun.com/jstl/x</taglib-uri>
    <taglib-location>/WEB-INF/x.tld</taglib-location>
</taglib>Thanks.

Just to confirm
- what server/version are you deploying on where it doesn't work?
- what server do you have that it does work on? Is it the same?
- you have both standard.jar and jstl.jar? Check the version by opening with a zip tool and looking at the manifest.mf file.
- what URI are you using to import the tag libraries with?
To install JSTL, all you need is jstl.jar and standard.jar, in a place where the webapp can find them.
Most commonly is the WEB-INF/lib directory
Most servers also have a "shared" directory idea - eg tomcat has the /common/lib and /shared/lib directories. The JSTL jars will work just as well in those directories.

The cause of the ORA-00904 is "The column name entered is either missing or invalid". Check your SQL queries and see if all your column names are correct.

Jslt +sql count

Hi,
i would be thanksfull fi anyone would tell me, how to get the value from the count sql-statement using jstl..
the tags should look sth like this:
<sql:query var="getUser" >
SELECT COUNT(Row) FROM table
</sql:query>
<c:set var="count" value="${getUser}" scope="page" />
but sth is wrong. for any suggestion thanks!

ive solve this in that way..
<sql:query var="getUser" >
SELECT COUNT(Row) AS cnt FROM table
</sql:query>
<c:forEach var="Temp" begin="0" end="1" items="${getUser.rows}">
<c:set var="users" value="${Temp.cnt}" scope="session" />
</c:forEach>
but if there is any way to set the variable users in some way with using only one tag?

-------------------------------------------------------------------------------------

There is no way to hide these warnings. The main reason with these warnings is that standard-1.1.2.jar is based on JSP 2.0 where as WLS 8.1 SP6 does not support JSP 2.0, but only JSP 1.2. Please check http://e-docs.bea.com/wls/docs81/notes/new.html#1184292.
In order to resolve the issue, either you need to use JSTL supported with JSP 1.2 or need to upgrade to WLS versions 9.x or higher.
Please check http://java.sun.com/products/jsp/jstl/, which states
JSTL 1.1 Specification Maintenance Release This release builds on JSTL 1.0, adding a function library and requiring a Web container that supports JSP 2.0.
Jakarta TagLibs Project also states that JSTL 1.1 requires a JSP container that supports JSP 2.0 Specifications. Please see http://jakarta.apache.org/taglibs/doc/standard-doc/intro.html.

JSTL JOIN STATEMENT

Dear Sirs,
I have the below JSTL code.
<sql:query var="books" dataSource="${dataSource}">
SELECT ENG_BOOKS.CODE FROM ENG_BOOKS, FR_BOOKS
WHERE ENG_BOOKS.CODE = FR_BOOKS.CODE
</sql:query>
<table>
<c:forEach var="row" items="${books.rows}">
<tr>
<td><c:out value="${row.ENG_BOOKS.CODE }"/></td>
</tr>
</c:forEach>
</table>
Putting the colums retreived from the above select statement in
<c:out value="${row.ENG_BOOKS.CODE }"/>
gives an error.
Please help

You're using the table name to retrieve the value. This is not going to work. Use column names only or introduce a column alias.
Having said that, you should not be placing any business logic in JSP files and certainly not any database logic. The JSTL SQL taglib should only be used for quick tests. At least refactor that code to a DAO class, write a Servlet which gets the data from the DAO class and sets it as request attribute and finally let the JSTL c:forEach access it.

JSTL when statement

What is the syntax for multiple values in a when statement ?

All the conditions are considered one 'Expression' since they yeild one result. As such they should all be in the same ${ } deliminator:
<c:when test="${a == b and c != d }">

JSTL: Work with conditional statements

Hallo everybody!
I'd have the following question:
If I need to have a condition whithin my JSP, I can write, e.g.:
<c:if test="${pageContext.request.method=='POST'}">Here I access some class variable, it is clear.
But what if a condition concerns a result of a method call on an object? E.g., I need to check if pageConfig.isReadonly("commodity_group") is true or false?
Obvously, <c:if test="${pageConfig.isReadonly("commodity_group")}"> does not work.
I can't find a way to do it...
Andrew

There isn't a direct way in EL. EL can only call getters/setters.
It can not call any bean methods that take parameters
You can hack it a little if your pageConfig bean has two attributes instead of one.
public class PageConfig{
String field;
public String getField(){return field;}
public void setField(String field){this.field = field;}
public boolean isReadOnly(){ return isReadOnly(field) }
public boolean isReadOnly(String field){
//your implementation
}And then
<c:set target="pageConfig" property="field" value="commodity_group"/>
<c:if test="${pageConfig.readOnly}">
</c:if>An alternative in an EL container is to use a custom function.

Accessing JSTL values from JSP

I've run into a problem I'm not sure has a solution. Could be bad design on my part, or just a poor imagination. If this has been answered previously, please point me to the post.
I am using some JSTL to do a SQL query and displaying the records in a select box:
<sql:query var="aResults" sql="select * from TYPE_STATE_LIST where tslAllowable=1" />
<c:forEach var="oRecord" items="${aResults.rows}">
<option value="<c:out value="${oRecord.tslID}" />"><c:out value="${oRecord.tslFullName}" /></option>
</c:forEach>I want to be able to reset their selection to the value they entered when the form is refreshed, though. I'm trying to figure out how to grab the oRecord value from the JSTL and use it in a JSP IF statement:
<% if( oRecord.tslID==request.getParameter("state") ) { %>
<option selected value="<c:out value="${oRecord.tslID}" />"><c:out value="${oRecord.tslFullName}" /></option>
<% } else { %>
<option value="<c:out value="${oRecord.tslID}" />"><c:out value="${oRecord.tslFullName}" /></option>
<% } %>I thought about using the JSTL <c:choose> tag instead, but then how would I access the previous value with request.getParameter()?
Any suggestions?

${param.state}It's better if you place the sql query into a class rather than display it in the jsp, it's more flexible and programmable.

Calendar in JSTL

Hi ,
I am using JSTL in JSP and there is an If statement which says
if (Calendar.get(Calendar.YEAR)!=2000){
do some thing
I need to know how to write that if condition in JSTL.

If statement inconsistency?

Yay! Another post from me!
I've got an if statement in a bean that seems to be processing fine when I create a test java class, but doesn't work fine when the bean is invoked by a jsp.
My code, let me shows you it:
First, the test class:
package com.serco.inquire;
import java.util.*;
import java.text.*;
public class TestCollection {
     public static void main(String[] args) {
          IrCollection myCollection = new IrCollection();
          myCollection.setSort("none");
          myCollection.setMgrid("none");
          int endpoint = myCollection.getSize();
          for (int i=0;i<endpoint;i++) {
               InquireRecord curRec = myCollection.getCurRecords(i);
               Long milis = new Long(curRec.getSubmitDate());
               Date theDate = new Date(milis);
               Format formatter = new SimpleDateFormat("dd MMM yyyy");
               String s = formatter.format(theDate);
               System.out.println("ID: " + curRec.getID() + " | Subject: " + curRec.getSubject());
}a snippit from the IrCollection class it calls:
private void processSort(String datum) {
          int LastChar = datum.length()-1;
          String colName = datum.substring(0, LastChar);
          if (datum=="none") {
               this.fullSort = " ORDER BY lastUpdated DESC";
          } else {
               if (datum.endsWith("2")) {
                    this.fullSort = " ORDER BY " + colName + " ASC";
               } else {
                    this.fullSort = " ORDER BY " + colName + " DESC";
     }There's more code in another method that calls this particular method using: this.processSort(this.sort);But the problem is that if (datum=="none") portion in the second code sample. Given that line 10 of the first class sets the member variable sort to "none", that processSort() method should set the member variable fullSort to " ORDER BY lastUpdated DESC"
And if I use the class in the first sample, it does that.
HOWEVER
I have this custom tag:
<%@ tag body-content="scriptless" import="com.serco.inquire.*" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ attribute name="mgr" required="true" %>
<%@ attribute name="mkind" required="false" %>
<%@ attribute name="sort" required="false" %>
<c:if test="${empty mkind}">
<c:set var="mkind" value="manager" />
</c:if>
<c:if test="${empty sort}">
<c:set var="sort" value="none" />
</c:if>
<jsp:useBean id="irc" scope="page" class="com.serco.inquire.IrCollection">
<jsp:setProperty name="irc" property="mgrtype" value="${mkind}" />
<jsp:setProperty name="irc" property="sort" value="${sort}" />
<jsp:setProperty name="irc" property="mgrid" value="${mgr}" />
</jsp:useBean>
${irc.fullsort}Which the .jsp file invokes with this:
<c:set var="user" value="none" />
<c:set var="sort" value="none" />
<inq:displayCollection>
<jsp:attribute name="mgr">${user}</jsp:attribute>
<jsp:attribute name="mkind">cotr</jsp:attribute>
<jsp:attribute name="sort">${sort}</jsp:attribute>
</inq:displayCollection>In other words, the exact same data is fed to the IrCollection bean. so I should get the same data, right?
Except I get this: WHERE cotr = 'none' ORDER BY non DESC so when Java calls it, it thinks "none" == "none"
but when jsp calls it, it thinks "none" != "none"

To compare objects' states, including Strings' contents, use equals(), not ==. The == operator tests whether 2 references have the same value, that is, whether both point to the same object (or are both null). The equals() method does whatever that class's implementor tells it to do, but its purpose--and what it does in reasonable implementations--is to compare objects' states. In the case of String, it tests whether both String objects contain equal character sequences.
If == happened to return true in your test case, its because interning led to both references pointing to the same String object in the constant pool.

Jstl c:if test

I have put a string in my request:
pageContext.getRequest().setAttribute("photoAccountmanager", "SUCCESS");
How can I retrieve the string in jstl? The next statement doesn't work:
<c:if test="${request.photoAccountmanager == 'SUCCESS'}" >
</c:if>

The proper EL way of retrieving from a particular scope is to use the Scope's map (requestScope for requests, sessionScope for sessions, applicationScope for application).
<c:if test="${requestScope.photoAccountmanager == \"SUCCESS\"}">
Note, that as long as there is no fear of having a variable of the same name in a different scope, specifying the scope is not necessary:
<c:if test="${photoAccountmanager == \"SUCCESS\"}">
Also not the escaped double quotes rather than single quotes. Not positive this is necessary, but I think it is the correct way to do it.
Finally, if trouble still persists, try using
<c:if test="${requestScope.photoAccountmanager eq \"SUCCESS\"}">

Using HashMap's ContainsKey() in JSTL

Can we use HashMap's containsKey() in JSTL <c:if > statement
I tried with the sample
<html:select property="Type" multiple = "true" size = "3">
<option value='<c:out value="${key}"/>'
<c:if test="${requestScope.test.containsKey(key)}">
selected
</c:if>
<c:out value="${value}"/></option>
</html:select >
When i executed the above code i encountered JSP Error
Can any one please let me know the correct code

You can't call java methods from JSTL. It uses the EL - not java.
However there is a solution.
You access maps using the square brackets [ ] notation.
ie ${test[key]}
is the same as test.get(key)
try
<c:if test="${ not empty test[key] }"/>
However seeing as you are using the struts tags, doesn't that automatically take care of this for you? Why don't you use the struts tags for the options list as well as the select? Just a thought :-)

Please Help::How to display a Map with LIsts as Keys and Values using JSTL

Hi,
I need some assistance on how to display a Map in JSP using struts or core JSTL. I have a HashMap which has a List of keys and each key maps to a value of an ArrayList.i.e I have an ArrayList of taxCodes and each taxCode maps to a value of taxDetails which is an ArrayList of details for for that particular taxCode. I have some trouble to display each taxCode then display taxDetails for each taxCode. Here is my code below:

hi evnafets,
yes i need a nested for loop.I have tried your advice but my bean properties are not found.Am getting this error:
javax.servlet.ServletException: Unable to find a value for "key_item" in object of class "java.lang.String" using operator "."
I have tried this as stated earlier in the post:I have tried to make the method getItemTaxDetails return a List and get the returned list value as taxDetails. I then tested to display this list on JSP and its displaying fine.
public List getItemTaxDetails(String key_year,String key_office,
