    Tomahawk + Seam not working

    Asuka Langley Newbie

      So I have a Seam Project and I'm trying to integrate Tomahawk 1.2. I've copied the tomahawk12.jar in WebInf/lib and I have the following configuration in web.xml:




      <filter>
         <filter-name>MyFacesExtensionsFilter</filter-name>
         <filter-class>org.apache.myfaces.webapp.filter.ExtensionsFilter</filter-class>
         <init-param>
             <param-name>maxFileSize</param-name>
             <param-value>20m</param-value>
         </init-param>
      </filter>
      
      <filter-mapping>
         <filter-name>MyFacesExtensionsFilter</filter-name>
         <servlet-name>Faces Servlet</servlet-name>
      </filter-mapping>
      
      <filter-mapping>
         <filter-name>MyFacesExtensionsFilter</filter-name>
         <url-pattern>/faces/myFacesExtensionResource/*</url-pattern>
      </filter-mapping>
      <filter-mapping>
          <filter-name>MyFacesExtensionsFilter</filter-name>
          <url-pattern>*.seam</url-pattern>
      </filter-mapping>





      I want to use the Scheduler but I get the following Exception:

      any ideas?

          I just got the Tomahawk scheduler working with Seam, here's what I did.

          This is for Seam 2.2, Jboss 5.1 with tomahawk 1.2-1.1.11

          I added the following jars to my apps lib and deployed-jars.list:

          commons-el.jar

          commons-fileupload-1.2.2.jar

          tomahawk12-1.1.11.jar

           

          added the following to app web.xml:

          <filter>
             <filter-name>MyFacesExtensionsFilter</filter-name>
             <filter-class>org.apache.myfaces.webapp.filter.ExtensionsFilter</filter-class>
             <init-param>
                 <param-name>maxFileSize</param-name>
                 <param-value>20m</param-value>
             </init-param>
          </filter>
          
          <filter-mapping>
             <filter-name>MyFacesExtensionsFilter</filter-name>
             <url-pattern>/faces/myFacesExtensionResource/*</url-pattern>
          </filter-mapping>
          <filter-mapping>
              <filter-name>MyFacesExtensionsFilter</filter-name>
              <url-pattern>*.seam</url-pattern>
          </filter-mapping>
          
           <filter-mapping>
            <filter-name>DisableUrlSessionFilter</filter-name>
            <url-pattern>/*</url-pattern>
           </filter-mapping>
           <filter-mapping>
            <filter-name>Seam Filter</filter-name>
            <url-pattern>/*</url-pattern>
           </filter-mapping>
          

           

          I used a dummyScheduleModel class(it extends a class in the tomahawk jar) that I got from here:

           

          public class DummyScheduleModel extends SimpleScheduleModel
          {
           public DummyScheduleModel()
           {
           super();
           final Calendar calendar = Calendar.getInstance();
           calendar.setTime(new Date());
           final DefaultScheduleEntry entry = new DefaultScheduleEntry();
           entry.setId("dummyEntry");
           entry.setStartTime(calendar.getTime());
           calendar.add(Calendar.MINUTE, 45);
           entry.setEndTime(calendar.getTime());
           entry.setTitle("Test MyFaces schedule component");
           entry.setSubtitle("my office");
           entry.setDescription("We need to get this thing out of the sandbox ASAP.");
           setMode(ScheduleModel.WEEK);
           addEntry(entry);
           refresh();
           System.err.println("Created DummyScheduleModel instance with an event on "
           + entry.getStartTime() + ".");
           }
           
           public boolean isEmpty()
           {
           System.err.println("Called isEmpty (" + super.isEmpty() + ")");
           return super.isEmpty();
           }
           
           public Date getSelectedDate()
           {
           System.err.println("Called getSelectedDate (" + super.getSelectedDate() + ")");
           return super.getSelectedDate();
           }
           
           public ScheduleEntry getSelectedEntry()
           {
           System.err.println("Called getSelectedEntry (" + super.getSelectedEntry() + ")");
           return super.getSelectedEntry();
           }
           
           public boolean isEntrySelected()
           {
           System.err.println("Called isEntrySelected (" + super.isEntrySelected() + ")");
           return super.isEntrySelected();
           }
           
           public int getMode()
           {
           System.err.println("Called getMode (" + super.getMode() + ")");
           return super.getMode();
           }
           
           public Object get(int i)
           {
           System.err.println("Called get (" + super.get(i) + ")");
           return super.get(i);
           }
           
           public boolean containsDate(Date date)
           {
           System.err.println("Called containsDate (" + super.containsDate(date) + ")");
           return super.containsDate(date);
           }
           
           public int size()
           {
           System.err.println("Called size (" + super.size() + ")");
           return super.size();
           }
          }

           

           

          And created a page to display the scheduler:

          </ui:composition>
          

          note that the <style> tag is unnecessary, it's a holdover from some earlier experimentation.

          I ran into some problems with css, because of my current css table setting there were no borders on my schedule. In the table setting in our theme.css I changed

          border-collapse: collapse;

          border-spacing: 0px;

           

          to

          border-collapse: separate;

          border-spacing: 1px;

           

          I also added:

          div.schedule-compact-default .day .header {
              background-color: #BED6F8;
              color: #000000;
              font-size: 10px;
              text-align: left;
              vertical-align: middle;
          }
          

          to make the headings match our application colors.

           

          I haven't gotten to the point of actually adding entries, but hopefully that won't take as long as getting the initial configuration set up.

           

          lots of good examples here:

            looks like I'm going to have to scratch using tomahawk.  The only way I can get it working is by using the myfaces extension filter, which is crazy stupid because it breaks my seam file uploads.

            Back to the drawing board.

              ok, one more time-I spent some time on the myfaces forums and found what looks like a workable solution.

              I tried using the non-extensionFilter solution:

               

              <context-param>
                  <param-name>org.apache.myfaces.ADD_RESOURCE_CLASS</param-name>
                  <param-value>org.apache.myfaces.component.html.util.StreamingAddResource</param-value>
                </context-param>
              
                 <context-param>
                  <param-name>org.apache.myfaces.CHECK_EXTENSIONS_FILTER</param-name>
                  <param-value>false</param-value>
                </context-param> 
                <context-param>
                  <param-name>org.apache.myfaces.DISABLE_TOMAHAWK_FACES_CONTEXT_WRAPPER</param-name>
                   <param-value>false</param-value>
                </context-param>
              

              I couldn't get this to work, you're supposed to comment out the myExtensionFilter stuff when you use this, but when I do, my server keeps bouncing til a "can't complete" message displays.

               

              What I did find was that ordering in web.xml matters.  So I can use the myExtensionFilter as long as it's AFTER my Seam filters (that includes mapping).  When I do that, I can still use richFaces fileUpload and tomahawk scheduler, the tomahawk fileUpload won't work if called after another upload filter:
