Help!

Hi list!
I'm migrating a tool. The tool has Session-based and it was listed using h:commandLink when it used jsf: <h:column>
<f:facet name="header" >
<h:outputText value="#{msgs.items_title}"/>
</f:facet>
<h:commandLink id="enterLink" action="#{WbBean.join}" rendered="#{Bean.canJoin}">
<h:outputText value="#{entry.title}"/>
</h:commandLink>
<h:outputText value="#{entry.title}" rendered="#{not Bean.canJoin}"/>
</h:column>
When a user clicks in link, the action invokes a void method. This method prepares to send information to the servlet that will generate the JNLP file. So, an application open with Java WebStart. I tried using a4j:commandLink, but it didn't open Java WebStart. A page was opened and the JNLP was printed. Any suggestion?

I dont know if I understood well...but you should response a http response 303 to redirect to JNLP file....Cause JNLP is another request to another http server to start WS process.

Hi!
The application works fine when I use jsf: <h:commandLink id="enterLink" action="#{Bean.join}" rendered="#{Bean.canJoin}">The page print the JNLP. I think the tag is wrong. The code is right because the application works with jsf.How to create a link using ajax4jsf that it will open my webStart application?!Thanks! 2009/10/30 Fernando Franzine <fernandofranzine@...> I dont know if I understood well...but you should response a http response 303 to redirect to JNLP file....Cause JNLP is another request to another http server to start WS process. -- Claudia Roberta Intermídia - ICMC/USP - São Carlos, SP - Brasil |

Caros colegas,
Tenho uma situação na qual presciso colocar alguns parametros em uma página JSP usando Tomcat 6 durante a execução, da seguinte maneira: ===> Na pagina .jsp esta assim: <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <%@ taglib uri="http://java.sun.com/jsf/html" prefix="h"%> <%@ taglib uri="http://java.sun.com/jsf/core" prefix="f"%> <%@ taglib uri="http://richfaces.org/rich" prefix="rich"%> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <meta http-equiv="Pragma" content="no-cache"> <meta http-equiv="expires" content="-1"> </head> <body> <###MARCA###> </body> </html> ===> Más gostaria que quando foce processada ela mudace antes para: <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <%@ taglib uri="http://java.sun.com/jsf/html" prefix="h"%> <%@ taglib uri="http://java.sun.com/jsf/core" prefix="f"%> <%@ taglib uri="http://richfaces.org/rich" prefix="rich"%> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <meta http-equiv="Pragma" content="no-cache"> <meta http-equiv="expires" content="-1"> </head> <body> <f:view> <h:form> <rich:panel style="width:100%;"> <table width="100%"> <tr> <td class="label" width="130"><h:outputLabel value="Usuário: " /></td> <td class="input"><h:outputText value="#{trocarSenhaControl.usuario.codigo}" /> - <h:outputText value="#{trocarSenhaControl.usuario.nome}" /></td> </tr> <tr> <td class="label" width="130"><h:outputLabel value="Senha atual: " /></td> <td class="input"><h:inputSecret id="antiga" size="20" value="#{trocarSenhaControl.antiga}" /></td> </tr> <tr> <td class="label" width="130"><h:outputLabel value="Senha nova: " /></td> <td class="input"><h:inputSecret id="nova" size="20" value="#{trocarSenhaControl.nova}" /></td> </tr> <tr> <td class="label" width="130"><h:outputLabel value="Redigite a nova: " /></td> <td class="input"><h:inputSecret id="redigitada" size="20" value="#{trocarSenhaControl.redigitada}" /></td> </tr> </table> <f:verbatim> <br /> </f:verbatim> <rich:separator height="2" lineType="solid" /> <f:verbatim> <br /> </f:verbatim> <h:commandButton styleClass="actionbuttom" action="#{trocarSenhaControl.executar}" value="GRAVAR" /> <h:commandButton styleClass="actionbuttom" action="#{trocarSenhaControl.sair}" value="SAIR" /> </rich:panel> </h:form> </f:view> </body> </html> Atravé de tag consegui colocar o conteudo, más o problema é que ele não processa o mesmo, caso eu quisece colocar apenas código HTML funcionaria, más o problema é que é código JSF, então acho que deve ser incluido antes do processamento da página em si. - Existe algum filtro o meio por tag de fazer esta troca antes da página JSF ser transformada em Servlet, para que o pre-processamento interprete o código JSF, acho que seria algo no ato da carga do conteudo do arquivo ".jsp" pelo Tomcat? - Se existir, qual seria?

Hi!
The method called (when a user clicks in link) is a void of my bean. This method redirect to JNLP file : ... ExternalContext externalContext = FacesContext.getCurrentInstance().getExternalContext(); HttpServletRequest request = (HttpServletRequest) externalContext.getRequest(); HttpServletResponse response = (HttpServletResponse) externalContext.getResponse(); request.setAttribute(...); ... ExternalContext extContext = (ExternalContext) FacesContext.getCurrentInstance().getExternalContext(); ServletContext servletContext = (ServletContext) extContext.getContext(); ServletContext newcontext = (ServletContext) servletContext.getContext("/my-tool"); RequestDispatcher dispatcher = newcontext.getRequestDispatcher("/my-servlet-mapping"); dispatcher.forward(request, response); FacesContext.getCurrentInstance().responseComplete(); A class is called using servlet mapping.This class extends HttpServlet and is a servlet that dynamically generates the JNLP file for clients: ... response.setContentType("application/x-java-jnlp-file"); String jnlp = "<?xml version=\"1.0\" encoding=\"ISO-8859-1\"?><jnlp spec=\"1.0+\""+ " codebase=\""+ host + ":" + port + "/"+ "my-tool"+ "\">" ... + "<argument>"+ request.getAttribute(" ... ")+ "</argument>" + ...; out.println(jnlp); But, when a user clicks in link, the page prints the jnlp. My application doesn't open with Java WebStart. Any idea? 2009/11/3 Fernando Franzine <fernandofranzine@...> That is the problem !! You can't ! Cause with ajax request you return xml responde to rendered some part of your page !

Of course it was !! Because you are generated "response.setContentType("application/x-java-jnlp-file");" jnpl response....
You can't do this,...unless you know how jnlp file work...lollll You just need redirect (http 303) to adress that have o jnpl.....and let de browser do another request to web start server.

The problem is that there isn't a "static address" for the jnlp. Because it is generated dynamically and needs to redirect to a servlet
using some mapping. :-( 2009/11/6 Fernando Franzine <fernandofranzine@...> Of course it was !! Because you are generated "response.setContentType("application/x-java-jnlp-file");" jnpl response.... -- Claudia Roberta Intermídia - ICMC/USP - São Carlos, SP - Brasil |

If its generated dinamically you can set address on session, pass it by along session scope to another jsp who catch value and redirect to generated url.
Can i add your gTalk ?
