JSTL URL

I have the following jstl c:url tag. So I want to forward to a page with the value I get in the forEach tag. But it dont seem to work as it dont forward it, if I hardcode a value, it works. am i doing anything wrong?
<c:forEach var="row" items="${rsAdmin.rows}">
<c:set var="urlTemp" value="${row.url}" scope="session"/>
</c:forEach>
<c:url value="${urlTemp}" var="forwardURL"></c:url>
<jsp:forward page="${forwardURL}"/>

Are you using JSTL 1.1 rather than JSTL 1.0?
Are you using a JSP 2.0 container, like Tomcat 5?
Do you have the web application set to use the servlet 2.4 specs rather than the 2.3 specs?
You can search these forums to figure out how to check each of these answers. If they are not all answered "Yes" then you will not be able to use the EL expressions outside of JSTL (<jsp:forward> is not JSTL, it is a JSP syntax tag).
And just to check out what the value of urlTemp actually is, you could use:
<b>URLTemp value: </b>${urlTemp}
Which should work if all of the answers to the questions above were "Yes" and you actually have a value in the variable.

Url link problem

for my project, i create a table to that store some field and a url. then i rs,getString(url)(example www.yahoo.com). what is shown on my address is (http://localhost:8080/www.yahoo.com). how do i actually do so that i can get to www.yahoo.com.

Hey,
my jstl urls will not render properly. I am using:
<c:forEach var="row" items="${rs.rows }">
<h4>${row.startdate }</h4>
<c:url var="url" value="announceDetail.jsp" >
<c:param name="announceidid" value="${row.announceid}" />
</c:url>
<p>${row.content}</p></li>
</c:forEach>
The url turns out to be
http://testchem.chem.columbia.edu/ugrad/$urlWhat am I doing wrong?

JSF / Switch between HTTP and HTTPS

Hello!
I want to switch between HTTP and HTTPS using JSF.
Under Apache Struts framework I can use struts extension "sslext.jar" to configure switching between http and https in one web application.
e.g. Login-jsp should be secured, all other jsp's should run unsecured.
Any ideas?
regards
Harald.

Thanks,
I made the necessary enhancement for the second phase, password confirmation required when return to SSL zone after leaving it after a succesful login.
I did the following:
1) create a class in the application scope and/or singleton class with the servlet paths that require SSL
2) create a plugin that reads ActionConfigs from the ModuleConfig
3) create a filter that sets a request scope flag that says that password must re-entered.
Code Extracts:
1) MainshopContainer application level parameter singleton class:
private static HashMap sslZoneMap = new HashMap(50); // key = servlet path of request, example /login.do
public boolean isInSSLZone(String servletPath)
return this.sslZoneMap.containsKey(servletPath);
public void addToSSLZone(String servletPath)
this.sslZoneMap.put(servletPath,null);
public int getNumberOfActionsInSSLZone()
return this.sslZoneMap.size();
2) Struts plugin
add a call to loadSSLZoneMap in plugin init method:
loadSSLZoneMap(config, mainshopContainer);
private void loadSSLZoneMap(ModuleConfig config, MainshopContainer mainshopContainer)
throws ServletException
try {
ActionConfig[] actionConfigs = config.findActionConfigs();
for (int i = 0; i < actionConfigs.length; i++)
if (actionConfigs.getParameter().indexOf("/jsp/account/") < 0) // /account/* = URL path for SSL zone
// not found = not ssl zone
System.out.println("loadSSLZoneMap, following actionConfigs excluded from SSL Zone: "+actionConfigs[i].getPath());
else
// found = ssl zone
String servletPath = actionConfigs[i].getPath()+".do";
mainshopContainer.addToSSLZone(servletPath);
System.out.println("loadSSLZoneMap, following servletPath added to SSL Zone: "+servletPath);
System.out.println("loadSSLZoneMap, number of actions in SSL Zone: "+mainshopContainer.getNumberOfActionsInSSLZone());
catch (Exception ex)
ex.printStackTrace();
throw new ServletException("Exception caught in loadSSLZoneMap: "+ex.toString()+" Initialization aborted.",ex);
3)
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
throws IOException, ServletException {
HttpServletRequest req = (HttpServletRequest) request;
HttpServletResponse res = (HttpServletResponse) response;
String servletPath = req.getServletPath();
boolean secure= this.mainshopContainer.isInSSLZone(servletPath);
The wole picture:
The filter adds a RequestDTO object that includes all request parameters, one of them is the secure flag.
I have a session scope class UserContainer that includes all the session parameters, one of them is the lastRequestDTO.(last made request)
At the end of all my jsp's I set the lastRequestDTO variable.
In that method I set the passwordConfirmationRequired flag if needed:
public void setLastRequestDTO(RequestDTO _lastRequestDTO)
if (this.lastRequestDTO != null && this.lastRequestDTO.isSecure() != _lastRequestDTO.isSecure())
this.setPasswordConfirmationRequired(true);
this.lastRequestDTO = _lastRequestDTO;
I read the passwordConfirmationRequired in all my jsp's in the SSL zone that allow editing or deleting and if that flag is true, a valid password must be re-entered in order to make the updates.
When the password is OK I reset the passwordConfirmationRequired to false.
I need some help for the first phase, that is SSL setup for all actions related to jsp's with url path /account/*
I tought I could define it in the web.xml:
<security-constraint>
<web-resource-collection>
<web-resource-name>All Account Related Pages</web-resource-name>
<url-pattern>/account/*</url-pattern>
</web-resource-collection>
<user-data-constraint>
<transport-guarantee>CONFIDENTIAL</transport-guarantee>
</user-data-constraint>
</security-constraint>
but that doesn't work and finnaly understood why:
Example: /WEB-INF/jsp/account/login.jsp corresponds to /login.do
The url pattern /account/* at the container level is never encountered.
Is it allowed to declare the following action path: /account/login instead of /login?
If yes I could add following prefix /account to all my action paths and forward paths and this could resolve my problem.
What's your opinion?
If no, would your library resolve this?
Will all the Struts/JSP/JSTL url generating tags pick-up the required protocol (http/https) according to your configuration file?

Does JSF like XML?

It seems that actually using XML as a source file for my JavaServer Faces JSP files is severely limiting my ability to create even simple functionality.
Let's say that I want to put in a simple stylesheet link, but I want it to be relative to the context. (Otherwise, I couldn't include the JSP file in other JSP files in different directories, because the link is relative to the enclosing JSP's base URI.)
In old, outdated, non-XML source code, that's easy, if not pretty:
<html>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="jsf" %>
<jsf:view>
     <head>
          <link rel="stylesheet" type="text/css" href="<%= request.getContextPath()%>/style/sheet.css"/>
But I want to use XML for my source JSP file. So I start with this:
<?xml version="1.0"?>
<jsp:root version="2.0"
     xmlns:jsp="http://java.sun.com/JSP/Page"
     xmlns:jsf="http://java.sun.com/jsf/core"
<jsf:view>
<jsp:output omit-xml-declaration="false" doctype-root-element="html" doctype-public="-//W3C//DTD XHTML 1.1//EN" doctype-system="http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"/>
     <html xmlns="http://www.w3.org/1999/xhtml">
     <head>
Now what? I can't use <%=...> in the <link> href attribute value, because that attribute (according to Tomcat 5.5.2) can't contain the "<" character.
Using ${pageContext.request.contextPath}/style/sheet.css results in the entire literal string being sent to the browser---no replacement. The same goes for #{facesContext.externalContext.request.contextPath}.
Are those who use XML-compliant source files limited in JSF functionality?
Starting to be disillusioned,
Garret

This is easily solved using JSTL:
<c:url value="/styles.css" var="styles"/>
<link rel="stylesheet" type="text/css"
href="${styles}" />I beg to differ! I have:
<?xml version="1.0"?>
<jsp:root version="2.0"
     xmlns:jstl="http://java.sun.com/jstl/core"
     xmlns:jsp="http://java.sun.com/JSP/Page"
     xmlns:jsf="http://java.sun.com/jsf/core"
     xmlns:html="http://java.sun.com/jsf/html">
<jsf:view>
     <jsp:output omit-xml-declaration="false" doctype-root-element="html" doctype-public="-//W3C//DTD XHTML 1.1//EN" doctype-system="http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"/>
     <html xmlns="http://www.w3.org/1999/xhtml">
     <head>
          <title>Test</title>
          <jstl:url value="/styles.css" var="styles"/>
          <link rel="stylesheet" type="text/css" href="${styles}" />
     </head>
     <body>
     </body>
     </html>
</jsf:view>
</jsp:root>This sends the following stylesheet link back to my browser:
<link href="${styles}" type="text/css" rel="stylesheet"/>(Try it yourself.)
I'm using JSF 1.1_01 on Tomcat 5.5.2. I cannot get a ${} expression to be substituted.

Previous Page's URL in JSP/JSTL

Dear Sirs,
Could you please advice me how I could get the previous page's url( ie, the page the the user was visting before coming to the current page) in JSP/JSTL..
Thank you in advance

You mean the referrer? You can just get it from the HTTP header.
String referrer = httpServletRequest.getHeader("referer"); // Yes, with the legendaric misspelling.

URL rewriting using JSTL

          We are trying to use URL rewriting using JSTL. We have some problems facing URL
          rewriting. The issues we have are
          (1) We use absolute URLs
          (2)Some times we have situations based on certain input field validations
          we use
          javascript to perform URL rewriting based on the input by the user.
          Have anyone done URL rewriting using JSTL (absolute URL versus relative URLS)

Jstl passing sql c:forEach in url

I am using jstl to pull info from db. How can I put a value, like row.columnName, in an url?
Whe I did it before I got alot of garbage in the url.

I don't recommend adding it as a query string parameter, but here is the URL:
http://localhost:8080/psc/hlbhrdev/EMPLOYEE/HRMS/c/ADMINISTER_WORKFORCE_(USF).EE_HR_PROC.USF?userid=VP1&pwd=VP1
The recommended approach would be to use a POST instead of a GET, which would put the username and password into the body of the request instead of the URL of the request.

JSTL to access url string

Hi All,
Is it possible to access the url string using jstl ? What about the equivalent to the jsp code 'request.getRequestURL()' in jstl ?
Any pointers ? Much Appreciated...

You can get at the request object through the pageContext
${pageContext.request.requestURL}
Cheers,

Dynamic url to XML file url in jstl

Hi!
What i need to do:
1. I get some parameters when entering a jsp page
2. I use these parameters to get an xml file from a server
3. I get a url to a picture from the xml file and load it
The problem is when i need to create the url to that xml file.
1. I read the parameters
String x = request.getParameter("X");
String y= request.getParameter("Y");
2. forming the url to xml file
this doesnt work:
<c:import url="http://www.website.com/something/something.jsp?xcoord=x&ycoord=y" var="xml">
<x:parse...
this works, but it is static...
<c:import url="http://www.website.com/something/something.jsp?xcoord=5&ycoord=6" var="xml">
<x:parse...
It is propable that i read the parameters in a wrong way... what is the right way? Heh, i hope u understood what i tried to tell. :)

This is maybe because you are using a String and an Integer.
Try this:
int x = Integer.parseInt(request.getParameter("X"));
int y = Integer.parseInt(request.getParameter("Y"));Happy Coding! :-)

How to enable jsessionid in url with Struts and JSTL?

Hi
I'm developing a struts application that will work with WAP devices. I have to guarantee that the jsessionid parameter is generated in every URL because cookies don't work with WAP 1.0 devices. Specifically in:
1.- Struts forwards that uses redirect.
2.- Using the <c:url /> tag
I sent a message to the struts list and they responded that this is a container feature that has to be enabled. Where can I configure OC4J to use the jsessionid parameter instead of the cookie?

Help needed to run JSTL 1.1 in Tomcat 6.0.16

Hi All,Help needed to run JSTL 1.1 in Tomcat 6.0.16. I am trying to run the example given in http://tomcat.apache.org/tomcat-6.0-doc/jndi-datasource-examples-howto.html The example tries to connect to MySQL database from JSP using JSTL and JNDI Datasource.I am running the example using Eclipse 3.4.2 using Sysdeo plugin to start and stop Tomcat server from Eclipse IDE.
My web.xml file has <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
</web-app>
and test.jsp has proper taglib directives
<%@ taglib prefix="sql" uri="http://java.sun.com/jsp/jstl/sql" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
I have placed the jstl.jar and standard.jarof the jakarta-taglibs-standard-1.1.2.zip under E:\Deepa\workspace\DBTest\WebContent\WEB-INF\lib directory also placedcontext.xml file under E:\Deepa\workspace\DBTest\WebContent\META-INF and the content of context.xml is as below
<Context path="/DBTest" docBase="DBTest"

username="deepa" password="mysql" driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/javatest?autoReconnect=true"/>
</Context>
Now while running the example, Eclipse creates one DBTest.xml file under C:\Program Files\Apache Software Foundation\Tomcat 6.0\conf\Catalina\localhost
which has the following line:
<Context path="/DBTest" reloadable="true" docBase="E:\Deepa\workspace\DBTest" workDir="E:\Deepa\workspace\DBTest\work" />

Hi evnafets,
Wow, very helpful information, great insight into working of Eclipse. Thanks a lot.
I have one more question. I have a context.xml file under {color:#0000ff}E:\Deepa\workspace\DBTest\WebContent\META-INF{color} folder and that has the Resource element to connect to MySQL database:

{color:#0000ff}</Context>{color}As usual when running application in local Tomcat server of Eclipse, this data source works fine. But when I run the application on Tomcat, by starting Sysdeo plugin from Eclipse, the DBTest.xml file created in C:\Tomcat 6.0\conf\Catalina\localhost has the context entry as<Context path="/DBTest" reloadable="true" docBase="E:\Deepa\workspace\DBTest\WebContent" workDir="E:\Deepa\workspace\DBTest\work">
</Context>The<Resource> element I have specified in the context.xml of \WebContent\META-INF folder is not taken into account by Tomcat and it gives the following error:May 21, 2009 5:20:04 AM org.apache.catalina.core.StandardWrapperValve invoke

How to display URL images and URL link (html) from Smartforms?

Hi Gurus,
I'm having difficulty on how to display targeted URL images and URL link from the smartforms, after i sending it out as html mail. The mail i sent just can be preview as a plain text, which can't execute the html code that i put inside the smartforms itself. I follow a few step from this very useful blog.. Hopefully, you guys can give me some solutions or ideas on this.

Thanks and Regards.

1- put your images in a directory under the web app directory. Example: app/images/
2- in your jsp, use: String file = application.getRealPath("/images/"); to get the images directory. See http://java.sun.com/j2ee/sdk_1.3/techdocs/api/javax/servlet/ServletContext.html#getRealPath(java.lang.String)
3- it's not the right forum to post this kind of question. Post them in the JSP/Servlet JSTL forum instead

Problem with % signs in key value url parameter pairs

Hi,
Tomcat 5.5.9
Java Version 1.5
I'm having a little difficulty passing a certain key value pair via a URL to the processing component of my web application.
If I submit a value for lets say parameter 'product_name' and that value starts with a % sign then the value is passed to my processing component as 'null' if I remove the % sign the value is correctly received.
Anyone come accross this on a Tomcat server?
The data has to be tagged onto the URL rather than as a form 'Post', as it is used to create and populate a popup window.
Thanks in advance.

So the % is used in URLs to mark certain escape sequences, so when you put it in you value, it thinks that the value is actually an escape sequence, and probably translates poorly on the opposite side.
You will actually need to use the escape sequence for the % sign to get it work correctly. I don't recall the actual escape value, but:
If you use JSTL to put together the URL for you, you shouldn't have a problem, the values will be escapes:
<c:url var="popupAddress" url="http://www.mydomain.com/myapp/mupage.jsp">
<c:param name="product_name" value="%Whatever"/>
</c:url>
<script type="text/javascript">
document.open("<c:out value="${popupAddress}"/>","Popup");
</script>
