[Building Sakai] cannot start my sakai tool

Thu Jun 18 08:27:25 PDT 2009

It still does not work L.

I have include some file that involve in uploading function.

Index.jsp is the page to use upload function

importedUserService: bean to handle upload

others are configuration files.

By the way, to use uploading function of tomahawk we have to use
UploadedFile right? But we should not define it in Spring files or
faces-config files right ?

Thanks,

Phuc Bui

Hi Phuc,

Sakai intercepts the uploads so you need to add an init-param to your
request filter in web.xml to tell it not to. I had the same issue with my
Wicket apps.

<filter>

       <filter-name>sakai.request</filter-name>

       <filter-class>org.sakaiproject.util.RequestFilter</filter-class>

       <init-param>

              <param-name>upload.enabled</param-name>

              <param-value>false</param-value>

       </init-param>

</filter>

<filter-mapping>

       <filter-name>sakai.request</filter-name>

       <servlet-name>sakai.yourtool</servlet-name>

       <dispatcher>REQUEST</dispatcher>

       <dispatcher>FORWARD</dispatcher>

       <dispatcher>INCLUDE</dispatcher>

</filter-mapping>

cheers,

Steve

I have studied how to upload a file by tomahawk.
If I try it as independent web application, it works.
But then I do the same in Sakai the uploadedFile object returns null.
So I wonder how to configure filter for tomahawk:
<filter>
                        <filter-name>ExtensionsFilter</filter-name>

<filter-class>org.apache.myfaces.webapp.filter.ExtensionsFilter</filter-clas
s>
                        ...
            </filter>

<filter-mapping>
                        <filter-name>ExtensionsFilter</filter-name>
                        <servlet-name>FacesServlet</servlet-name>
            </filter-mapping>
<servlet-mapping>
                        <servlet-name>FacesServlet</servlet-name>
                        <url-pattern>*.jsf</url-pattern>
            </servlet-mapping>
<servlet-mapping>
                        <servlet-name>FacesServlet</servlet-name>
                        <url-pattern>*.faces</url-pattern>
            </servlet-mapping>
I wonder if "*.jsf" or "*.faces" is good when we develop in Sakai ? Because
I see the link in Sakai never have those? For example:
http://localhost:8080/portal/site/b49296c3-d3d8-45d3-8f35-54499ec31a51/page/
335dc018-1079-4dd4-8625-850790e26b67
So which pattern is good ?

Thanks,
Phuc Bui

It looks like you are probably using the tomahawk component wrong. The
value should be an EL path and your looks like instructions.

ad.html

You will probably get a faster and better response on their forums or
the JSF forums.

Dear,

When I index.jsp file look like this, it worked

<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>

<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>

<f:view>

     Browse to the file that contains users data,

     then press upload to add those users to Sakai database.

</f:view>

But when I use tomahawk taglib, it threw errors as my previous post ?

<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>

<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>

<%@ taglib prefix="t" uri="http://myfaces.apache.org/tomahawk" %>

<f:view>

     Browse to the file that contains users data,

     then press upload to add those users to Sakai database.

     <h:form>

           <t:inputFileUpload value="Upload here: " />

           <h:commandButton action="success" value="Upload"/>

     </h:form>

</f:view>

Can you tell me why ??? How to solve this problem ???

Because I saw these lines, so I think I did not use that tag correctly
