    JBoss Portal insert applet jnlp

    Chua Khoon Yong Novice

      hi,

      Hope some1 can help me with this query. I was going to use a mix of Richfaces and JavaFX for my project, and encountered problem with embedding JavaFX applet on JBoss Portal.

      I use this environment:

      - Jboss Portal 2.6.5SP1
      - Seam 2.1.0SP1
      - Richfaces 3.3
      - Postgres 8.3.4


      I got this weird error on the java console and i put all the jars and jnlp files together with the xhtml files.

      Thanks in advance :)

          hi all,

          Seem to be ok after i added the codebase into the applet, as follows:

          <applet id="wwjApplet" width="500" height="500" name="StopWatch" codebase="#{facesContext.externalContext.requestContextPath}">
          <param name="jnlp_href" value="StopWatch_browser.jnlp" />
          <PARAM name="draggable" value="true" />
          </applet>
          


          the draggable is for fun, press alt-left click to drag the applet out.


          and, also remove the "security" settings in the jnlp file. To secure the applet, another time ...

          Best regards.
