Hi Tim,

Thanks, outputLink was what i was looking for.
Sorry for the XML screw-ups, those ended up here because i could not use the exact examples as i am using in our environment.

Cheers,
Peter

Hi,

Can somebody explain me why when i use the following outputText tag
<h:outputText value="Testone"/>

The generated HTML is
<div>Testone</div>

And when i use the next outputText tag the output is enclosed in quotes
<h:outputText value='<a href="http://some.site.com/login?URL=http://a.b.com/">Some sitelink</a>'/>
"<a href="http://some.site.com/login?URL=http://a.b.com/">Some sitelink</a>"

To temporarily fix something i need to generate an html tag using a param value. Here an example
<h:outputText value="<a href="http://some.domain.nl/login?URL={0}">Hi There</a>"> <f:param value="#{request.scheme}://#{request.serverName}:#{request.serverPort}#{request.contextPath}" /> </h:outputText>

Cheers,
Peter

Thanks!
It's quite hard to cast an array to a single object :-)

I am trying to implement an MXBean which returns a List of Beans.

MXBean
/* package com.reddipped.sysstats.jmx.mbean; import java.util.LinkedList; import java.util.List; import javax.management.MXBean; @MXBean public interface SysStatsMXBean { public String getArchitecture() ; public int getNumCPUs() ; public double getLoadAverage() ; public List<LoadHistoryMBeanImpl> getAvgLoadHistory() ; public int getAvgLoadHistorySize() ; public void setAvgLoadHistorySize(int size) ; public void takeAvgLoadHistorySample() ; }
MBean

package com.reddipped.sysstats.jmx.mbean; public interface LoadHistoryMBean { ; public Long getTimestamp() ; public void setTimestamp(Long timestamp) ; public Double getLoad() ; public void setLoad(Double load) ; }

When i try to get the attribute

Object loadHistory = mbs.getAttribute(mbeanObjectName, "AvgLoadHistory") ; CompositeData compData = (CompositeData) loadHistory ;

It fails with a ClassCastException.

Anyone able to help me out how to retrieve the mbean as an MXBean attribute ?

Were able to resolve this issue by adding the listener-uri. Although the class is available in the default package it must be explicitly added to the listener element.

<listener> <listener-class>com.reddipped.sysstats.jmx.mbean.SysStatsMBeanLifeCycleListener</listener-class> <listener-uri>SysStatsMBean.jar</listener-uri> </listener>

When i try to deploy an (Netbeans) enterprise application which includes an web application project (war) and an java application (jar)
On deployment i get a `weblogic.management.DeploymentException: classloader-structure element in weblogic-application.xml is referencing the module-uri SysStatsMBean.jar which does not exist in this application`

When built, the ear file now has the following structure.

SysStats.ear - SysStats-war.war - META-INF - WEB-INF - classes - com - reddipped - sysstats - model - SystemInfo.class - SystemInfoCollector.class - SystemInfoCollectorExecutor.class - SysStatsMBean.jar - com - reddipped - sysstats - model - SysStats.class - SysStatsMBeanLifeCycleListener.class - SysStatsMXBean.class - META-INF application.xml MANIFEST.MF weblogic-application.xml

Weblogic-application.xml contains

Anyone able to give me a hint how to resolve this ?

I om fairly new to spring and am now trying to develop a simple webshop demo application in spring3.
In the application i have defined an ArticleBean with the necessary getters and setters ( articleNumber , articleName, articleDescription , articlePrice , articleCategory ).
An OrderlineBean contains the attributes quantity (Integer) and article (ArticleBean)
A Cart has the attribute orderlines of type HashMap<String,OrderlineBean>()

The following part of the jsp results in a correct rendered form. e.g. the article data is correctly shown.

<form:form method="post" action="updatecart.htm" modelAttribute="subStock"> <c:forEach var="orderline" items="${subStock.orderlines}" varStatus="status"> <div id="orderLine"> <input hidden="true" name="orderline.key" value="${orderline.key}"/> <div class="articleName"><p>${orderline.value.article.articleName}</p></div> <div class="articleOrderedItems"> <select name="orderline[${orderline.key}].value.quantity"> <c:forEach begin="0" end="${orderline.value.quantity}" var="items"> <option value="${items}">${items}</option> </c:forEach> </select> <div class="articlePrice"> <fmt:formatNumber minIntegerDigits="1" maxFractionDigits="2" minFractionDigits="2" type="number" var="amount" value="${orderline.value.article.articlePrice/100}"/> <p>€ ${amount}</p> </div> </div> <div class="articleDescription"><p>${orderline.value.article.articleDescription}</p></div> </div> </c:forEach> <input type="submit" value="Add to cart" /> </form:form>

When posting the form, the number of orderlines in attribute subStock is 0 when processed by ModelAndView updateCart in the controller.

@RequestMapping(value = "/updatecart", method = RequestMethod.POST) public ModelAndView updateCart(Map map, @ModelAttribute("subStock") Cart subStock) { System.out.println("SantosController /updatecart POST") ; System.out.println(subStock.size()) ; HashMap<String,OrderlineBean> orderlines = subStock.getOrderlines() ; Iterator orders = orderlines.keySet().iterator() ; while (orders.hasNext()) { String articleID = (String) orders.next() ; OrderlineBean orderline = orderlines.get(articleID) ; System.out.println(orderline.getArticle().getArticleDescription() + " )" + orderline.getQuantity() + ")") ; } DbMapper db = new DbMapper() ; // Set container URL map.put("containerURL","content_default.jsp" ) ; return new ModelAndView("santos_index"); }

Can anyone any help to get me in the right direction?

Cheers,
Peter


update May 22th 2014 22:34

I have simplyfied the jsp form, still the same results though...

<form:form method="post" action="updatecart.htm" modelAttribute="subStock"> <c:forEach var="orderline" items="${subStock.orderlines}" varStatus="status"> <input name="orderline['${orderline.key}']" value="${orderline.value}"/> </c:forEach> <input type="submit" value="Add to cart" /> </form:form>

Hi,

I want to make a small jar available to the coderanch, including the sourcecode.
This jar uses jchardet made available under the Mozilla Public License 1.1 (MPL 1.1).
What is needed if i want to include the jchardet.jar in my own jar without compromising the MPL ?
I have tried to understand all the legal chitchat, but am not able to conclude what is sufficient.

Is it sufficient to include the distributed jchardet.jar and include my own sources in the jar ?

Cheers Peter

Just forget this question of me. Assumed (…) that the AbstractHandler was calling the servlet.
Now created a handlerCollection with a ServletContextHandler and a ContextHandler.

Cheers,

Hi,

I am current developing a small servlet based on Jetty 8. In this j2ee application i want to filter the request parameters and do specific actions on them.
Currently i have an abstractHandler assigned to the server which works fine, the only thing i do not known how to write is to forward the request to the servlet.

public class IcfStatusServerHandler extends AbstractHandler { private final String secretKey ; private Server jServer ; IcfStatusServerHandler(String secretKey, Server jServer) { this.secretKey = secretKey ; this.jServer = jServer ; } @Override public void handle(String string, Request rqst, HttpServletRequest hsr, HttpServletResponse hsr1) throws IOException, ServletException { String stopRequestKey = rqst.getParameter("stop") ; if (stopRequestKey != null) { if (stopRequestKey.equals(this.secretKey)) { try { this.jServer.stop(); } catch (Exception ex) { hsr1.setContentType("text/html"); hsr1.setStatus(HttpServletResponse.SC_OK); //200 hsr1.getWriter().println("Not stopping Jetty server FAILS<br/><br/>"); } } else { hsr1.setContentType("text/html"); hsr1.setStatus(HttpServletResponse.SC_OK); //200 hsr1.getWriter().println("Not stopping Jetty server due to invalid key<br/><br/>"); } } else { // how to forward the request to the servlet here... } } }

Hi Bear,

I can add a bean to the ServletContextHandler to which a new servlet is added.

// Create contexthandler ServletContextHandler context = new ServletContextHandler(ServletContextHandler.SESSIONS); context.setContextPath(icfHttpUri); server.setHandler(context); context.addServlet(new ServletHolder(new IcfStatusServlet()),"/*"); context.addBean(new icfServerBean()); server.start(); server.join();

Now i want to access the bean added to the ServletContextHandler from the servlet.
I tried to access it through the servlet context from within the servlet.


@Override public void init(ServletConfig config) throws ServletException { super.init(config); ServletContext context = getServletConfig().getServletContext(); ServletContext servletContext = config.getServletContext() ; // config.getServletContext() // servletContext. //WebApplicationContext context = WebApplicationContextUtils.getWebApplicationContext(getServletContext()); //SpringifiedJobbie jobbie = (SpringifiedJobbie)context.getBean("springifiedJobbie"); }

Hi,

I am trying a simple servlet based on Jetty 8. In the main class where i create the server instance and add the servlet i want to fill and add a bean with configuration data which is read and stored in the bean at startup.

The bean is added using the addBean method of context.

context.addBean(new icfServerBean());


Is it possible to access the bean from within the servlet ? I can get the ServletContext but have not found any clue how to retrieve the bean added to the context from within the servlet.

@Override public void init(ServletConfig config) throws ServletException { super.init(config); ServletContext servletContext = config.getServletContext() ;

Any hints / Tips ?
Cheers,
Peter

Thanks James !

You were absolutely correct. Somewhere in a method i did put the byte array in a String, after fixing this it works perfect even on windows ;-)

Cheers Peter

@Paul Clapham, The difference is that the mime-encoded attachment is not readable (corrupt) when sending it from the Windows server. Difference in line-endings do indeed not matter when the body part is of content type text, but when the content type is application/pdf it does make a difference

@Rob Prime, Yes they are exactly the same. The PDFs in the example do come from the same database. The invoices also can be viewed in a webpage and are therefore also encoded in Base64 and added to a data url. On both systems the pdfs can be viewed in the webpage. So i suspect that the base64 encoding in the javax.mail api is influenced by the line-ending characters on both systems. But when using org.apache.catalina.util.Base64 encoding is done correctly. Is there a way to enforce javax.mail to use this class for base64 encoding ?

Cheers
Peter

Nobody any suggestions, .... just a small hint... ?
