  • how do I iterate through multiple properties in jsp

    - by David
    I'm trying to iterate through a properties file which contains a list of keys like: message.p1 message.p2 message.p3 I don't know how many properties will be in the file, so I want to display any that are present. Is there a standard tag like <fmt:message> that can handle this, or do I need to write some jsp script to handle the loop?

  • Read an invalid cookie with Java (jsp)?

    - by jsumners
    I have a cookie that is formatted like partA:partB. The colon is not escaped in any fashion. I need to read this cookie in a JSP script, and request.getCookies() is only returning partA. I can't change the cookie because it is used in multiple applications, and fixing the cookie would break production code. Any ideas how I can read the full value of this cookie?

  • Custom JSTL tags with body

    - by Mickel
    Hi, We are going to use JSTL and custom JSTL-tags for some sort of template-engine in our JSP/spring-project. Is there a way to create a tag that looks similar like this: <div id="site"> <div id="header">Some title</div> <div id="navigation"> SOME DYNAMIC CONTENT HERE </div> <div id="content"> ${content} </div> <div id="footer"></div> </div> and use it like this: <mytags:template> <h1>Title</h1> <p>My content!</p> </mytags:template> i.e. use body-content inside a custom JSTL-tag... This works: <mytags:template content="some content... not HTML" /> but is not very useful in our case.

  • org.apache.sling.scripting.jsp.jasper.JasperException: Unable to load tag handler class [migrated]

    - by Babak Behzadi
    I'm developing an Apache Sling WCMS and using java tag libs to rendering some data. I defined a jsp tag lib with following descriptor and handler class: TLD file contains: <?xml version="1.0" encoding="UTF-8"?> <taglib version="2.1" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-jsptaglibrary_2_1.xsd"> <tlib-version>1.0</tlib-version> <short-name>taglibdescriptor</short-name> <uri>http://bob/taglibs</uri> <tag> <name>testTag</name> <body-content>tagdependent</body-content> <tag-class>org.bob.taglibs.test.TestTagHandler</tag-class> </tag> </taglib> Tag handler class: package org.bob.taglibs.test; import javax.servlet.jsp.tagext.TagSupport; public class TestTagHandler extends TagSupport{ @Override public int doStartTag(){ try { pageContext.getOut().print("<h1>Helloooooooo</h1>"); } catch(Exception e) { return SKIP_BODY; } return EVAL_BODY_INCLUDE; } } I packaged the tag lib as BobTagLib.jar and deployed it as a bundle using Sling Web Console. I used this tag lib in a jsp page deployed in my Sling repository: index.jsp: <%@ page contentType="text/html;charset=UTF-8" language="java" %> <%@ taglib prefix="bob" uri="http://bob/taglibs" %> <html> <head><title>Simple jsp page</title></head> <body> <bob:testTag/> </body> </html> Calling the page cause the following exception: org.apache.sling.scripting.jsp.jasper.JasperException: /apps/TagTest/index.jsp(7,5) Unable to load tag handler class "org.bob.taglibs.test.TestTagHandler" for tag "bob:testTag" ... Can any one get me a solution? In advance, any help is apreciated.

  • JSP Googlemaps taglib not found, where have I gone wrong?

    - by James.Elsey
    I'm trying to add Google Maps onto my JSPs by using the Googlemaps taglib. I've added this into my maven pom <dependency> <groupId>com.lamatek</groupId> <artifactId>googlemaps</artifactId> <version>0.98c</version> <scope>provided<>/scope </dependency> This then included the googlemaps-0.98c library under my project libraries in NetBeans, I right clicked and selected Manually install artifact and located the googlemaps.jar file I had downloaded. I've then added this into my taglibs file <%@taglib prefix="googlemaps" uri="/WEB-INF/googlemaps" %> And have then included this where I actually want to show a map on my jsp <googlemaps:map id="map" width="250" height="300" version="2" type="STREET" zoom="12"> <googlemaps:key domain="localhost" key="xxxx"/> <googlemaps:point id="point1" address="74 Connors Lane" city="Elkton" state="MD" zipcode="21921" country="US"/> <googlemaps:marker id="marker1" point="point1"/> </googlemaps:map> But when I load up my application, I get the following error. org.apache.jasper.JasperException: /jsp/dashboard.jsp(1,1) /jsp/common/taglibs.jsp(6,56) PWC6117: File "/WEB-INF/googlemaps" not found root cause org.apache.jasper.JasperException: /jsp/common/taglibs.jsp(6,56) PWC6117: File "/WEB-INF/googlemaps" not found Have I missed something simple? I'm unable to spot what I've done wrong so far..

  • JSP Document/JSPX: what determines how space/linebreaks are removed in the output?

    - by NoozNooz42
    I've got a "JSP Document" ("JSP in XML") nicely formatted and when the webpage is generated and sent to the user, some linebreaks are removed. Now the really weird part: apparently the "main" .jsp always gets all its linebreak removed but for any subsequent .jsp included from the main .jsp, linebreaks seems to be randomly removed (some are there, others aren't). For example, if I'm looking at the webpage served from Firefox and ask to "view source", I get to see what is generated. So, what determines when/how linebreaks are kept/removed? This is just an example I made up... Can you force a .jsp to serve this: <body><div id="page"><div id="header"><div class="title">... or this: <body> <div id="page"> <div id="header"> <div class="title">... ? I take it that linebreaks are removed to save on bandwidth, but what if I want to keep them? And what if I want to keep the same XML indentation as in my .jsp file? Is this doable?

  • Pure JSP without mixing HTML, by writing html as Java-like code

    - by ADTC
    Please read before answering. This is a fantasy programming technique I'm dreaming up. I want to know if there's anything close in real life. The following JSP page: <% html { head { title {"Pure fantasy";} } body { h1 {"A heading with double quote (\") character";} p {"a paragraph";} String s = "a paragraph in string. the date is "; p { s; new Date().toString(); } table (Border.ZERO, new Padding(27)) { tr { for (int i = 0; i < 10; i++) { td {i;} } } } } } %> could generate the following HTML page: <html> <head> <title>Pure fantasy</title> </head> <body> <h1>A heading with double quote (") character</h1> <p>a paragraph</p> <p>a paragraph in string. the date is 11 December 2012</p> <table border="0" padding="27"> <tr> <td>0</td> <td>1</td> <td>2</td> <td>3</td> <td>4</td> <td>5</td> <td>6</td> <td>7</td> <td>8</td> <td>9</td> </tr> </table> </body> </html> The thing about this fantasy is it reuses the same old Java programming language technique that enable customized keywords used in a way similar to if-else-then, while, try-catch etc to represent html tags in a non-html way that can easily be checked for syntactic correctness, and most importantly can easily be mixed up with regular Java code without being lost in a sea of <%, %>, <%=, out.write(), etc. An added feature is that strings can directly be placed as commands to print out into generated HTML, something Java doesn't support (where pure strings have to be assigned to variables before use). Is there anything in real life that comes close? If not, is it possible to define customized keywords in Java or JSP? Or do I have to create an entirely new programming language for that? What problems do you see with this kind of setup? PS: I know you can use HTML libraries to construct HTML using Java code, but the problem with such libraries is, the source code itself doesn't have a readable HTML representation like the code above does - if you get what I mean.

  • JSP Custom Taglib: Nested Evaluation

    - by Tiago Fernandez
    Say I have my custom taglib: <%@ taglib uri="http://foo.bar/mytaglib" prefix="mytaglib"%> <%@ taglib uri="http://java.sun.com/jstl/core" prefix="c"%> <mytaglib:doSomething> Test </mytaglib:doSomething> Inside the taglib class I need to process a template and tell the JSP to re-evaluate its output, so for example if I have this: public class MyTaglib extends SimpleTagSupport { @Override public void doTag() throws JspException, IOException { getJspContext().getOut().println("<c:out value=\"My enclosed tag\"/>"); getJspBody().invoke(null); } } The output I have is: <c:out value="My enclosed tag"/> Test When I actually need to output this: My enclosed tag Test Is this feasible? How? Thanks.

  • Automatically tidy up JSP/JSF files

    - by er4z0r
    Hi, I am working on a webapplication and I do most of the XHTML stuff in an editor. Every once in a while I froget to close a tag or mess up the nesting (we all get distracted sometimes ;-)). So I commpile, package and run my webapp (using maven mvn clean package jetty:run-war only to notice that displaying the view (where I messed up the jsp) fails with an exception while trying to render. So I wondered: Is there some tool that I can include into my build-cycle that automatically catches and rectifies those careless mistakes?

  • JSP Page HttpServletRequest getAttribute Typecasting

    - by MontyBongo
    Hi There, Any ideas on the correct method of typecasting an Object out of a getAttribute request from a JSP page HttpServletRequest? I have googled but it seems that the common solution is just sticking suppresswarnings in your code... Something I would very much like to avoid. I currently have: HashMap<String, ArrayList<HashMap<String, String>>> accounts = (HashMap<String, ArrayList<HashMap<String, String>>>)request.getAttribute("accounts"); And the complier is giving me this warning: Unchecked cast from Object to HashMap Thanks in Advance!!

  • html select option tag closes itself due to a "/" character in the dynamic value (JSP, JSTL)

    - by saky
    <select id="ordersSelect" class="drop-down" onchange="somemethod()"> <c:forEach items="${orders}" var="order" varStatus="orderStatus"> <option value="${order.id}"> ${order.publicId} </option> </c:forEach> </select> I have the above peice of code in a JSP page, that receives a list of Orders and each order has some information, the particular information that I want to display in a SELECT field is the publicId. The problem is that, on display there is only one OPTION in the SELECT and the rest of the order's publicId s are displayed as normal text below the SELECT box and not an OPTION to select. I found out that the publicId actually contains a String like A10/0001/0 and that is the character "/" is most probably causing the problem. Any solutions/suggestion/ideas?

  • Restlets with Google App Engine, Java Server Pages, (JSP's), and Shiro authentication

    - by DutrowLLC
    I'm having difficulty integrating Restlets into my project. I'm using google app engine (GAE) and I also have some java server pages (JSPs) set up. The JSP's never seem to work at the same time as the Restlets, should I only be using one or the other in GAE? I'm also using Shiro (formerly Ki, formerly JSecurity) and I have been unable to get Restlets to work with Shiro's filter for authentication. Are there any issues in particular that I should be aware of? What are other people using to secure restlet apps on GAE? Is Shiro overkill if I just need authentication and some role-based authorization? Thanks so much! Chris

  • where should we place HIDDEN variable in JSP

    - by micheal
    I need to use Hidden variables in my JSP for session tracking. this is the code: <input type="hidden" name="REQ_TOKEN" value="<%=session.getAttribute("SESN_TOKEN").toString()%>" /> i am using this to compare the request token with session token, so only when both are equal i will evaluate that request otherwise i will throw an error. Now the problem is, when i place this code inside <form></form> tags, it is working fine. Unfortunately there are some JSPs in my application where we dont have tag(I know that sounds weird!). where can i place my code so that it will work? Cant i use Hidden variables without FORM tag???

  • Converting a JSP to a SharePoint webpart

    - by Kelly French
    We have a large number of Java based servlets/portlets running in a BEA portal that we want to convert into SharePoint 2007 webparts. Many of the portlets use user preferences but the implementations are split between preferences being handled by the portlet directly and stored in a separate database from the portal. Others are using the BEA WebLogic API for user preferences. Three questions: Has anyone gotten a Java Servlet/JSP (compiled against JRE 1.4.2 and running on Tomcat 4.1) to run as a SharePoint 2007 webpart? How large of an effort was it in general (as in, was it measured in days/weeks/months)? Would it be easier to rewrite the portlet as native webparts at least as far as user preferences are concerned?

  • Problems with Tomcat server and JSP web application

    - by CitadelCSCadet
    I am running a JSP/Servlet Web application and out of nowhere we experienced some random problems that don't make any sense. I checked the catalina.out file to check the log files, and I noticed it contained some of the following messages SEVERE: Error starting static Resources java.lang.IllegalArgumentException: Invalid or unreadable WAR file : error in opening zip file INFO: validateJarFile(/home/weremo/appservers/ apache-tomcat-6.0.26/webapps /WMA/WEB-INF/lib/ servlet-api.jar) - jar not loaded. See Servlet Spec 2.3, section 9.7.2. Offending class: javax/servlet/Servlet.class I am aware of what this message means, but am in the dark as to what could have caused it, or what effects it could have on the application.
