Hi,We are using Alfresco in ssl mode.However, the logo image is imported in http mode:http://sflogo.sourceforge.net/sflogo.php?group_id=143373&type=1Due to this are getting warnings in our internet browsers.Is there anyway to have the image loaded locally from disk and not from an external site

This is fixed in 1.3 final - you can change the code yourself if it's a problem now, just download the logo and change the code in PageTag.java

Thanks,

Kevin

Hi, after changing the code in PageTag.java, how can I send this file to the existing system ?
Which sources files I must re-compile ?
Thanks.

Thanks for changing it for sourceforge, but It seems that the same is with Alfresco's logo. It also uses src='http://www.alfresco.." even in the latest version. Can this be changed in final version?

Download the source from SVN or get the SDK from sourceforge and you'll find it in the web-client project. The file is in the org.alfresco.web.ui.repo.tag package.

Yes. We are aware of the licensing and we are very strict about it … We actually changed PageTag.java and indeed copied 'community' logo locally, however it could be better if it is already in the package. Very soon we are going to propose it in a formal way as change to the source code.

Right now we developed a small "ant" build.xml to replace this and some other small customisations which cannot be put in "shared/extension" folder and we run (and will run it) every time we get newer version.

Just wanted to remind you all the Alfresco Public License (APL) prohibits the removal of the Alfresco logo and disclaimer from Alfresco Community Network.

See item 4 at:
http://dev.alfresco.com/legal/licensing/faq/

So, if you're using the community version, I suggest copying the images to the local server and have the browser access it from their via HTTP or HTTPS.

I got all the environment stuff setup, but I don't see a makefile for the web-client in the SDK. I am not a Java developer so please forgive me. I am just trying to fix this. I read up on Ant and understand I can compile the fixed .java to a .class and put it into the .jar. Problem is when I go to compile my new .java file I get errors because of missing items. I'm sure I'm just missing something. I thought Ant build files were XML. Maybe you can point me to the directory or give a bit more detail for?

I am trying to also get Alfresco on SSL and get the image problem because alfresco's footer has http referenced. Can anyone walk me through how to recompile after I make the necessary changes in the PageTag.java so I can reference the images to https and have them on my server so I can get rid of that image warning message from IE.

Any help would be greatly appreciated.

Thanks,
Chad

Hi,

For your information, on my Alfresco, the url is modified on the fly with a vulture reverse proxy (http://arnaud.desmons.free.fr/wordpress/?page_id=36 or http://vulture.open-source.fr) which uses apache with modproxyperlhtml.

It works well. I just had to put the image in the local server, and no more modification were needed.

Can I use Apache to reverse proxy like Vulture? If so, can you provide me with an idea as to what I need to configure in Apache to accomplish this? Or, is there a good link you can point me to?

Thanks!

Re: disable external image for https

lgr — Fri, 19 Jan 2007 09:31:50 GMT

Yes of course, as vulture is based on an apache server with the reverse proxy configured.

Using vulture should only be easier than configuring apache as it includes all configuration tasks in a web gui.

The problem with trying to replace the image link with an Apache proxy statement is that the proxy from Apache passes the user's request to the Tomcat (or JBoss) server, but the response which contains the bad link goes straight out of Tomcat to the user's browser without going back through Apache. So, any filtering needs to take place on the Tomcat side of the house, not in Apache.

I was able to filter Tomcat's output to perform a line-by-line search of all output for the Alfresco Community logo and replace it with a link to a local image using the following process:

1. I used IBM's devworks ReplaceTextFilter to perform the filtering. A description of the technique and a link to download the code can be found at this URL: http://www.ibm.com/developerworks/java/library/j-tomcat/?open&l=101,t=grj,p=TomcatTricks

2. After downloading the code to my server, I copied the "com" directory and all sub-directories from "code/dvworks/WEB-INF/classes" to Alfresco's "$TOMCAT_HOME/webapps/alfresco/WEB-INF/classes" directory.

3. Next, I edited the web.xml file in "$TOMCAT_HOME/webapps/alfresco/WEB-INF/web.xml" to add the following filter text:

 
   <filter>
        <filter-name>Replace Text Filter</filter-name>
        <filter-class>com.ibm.devworks.filters.ReplaceTextFilter</filter-class>
         <init-param>
            <param-name>search</param-name>
           <param-value>http://www.alfresco.com/images/alfresco_community_horizont.gif</param-value>
          </init-param>
         <init-param>
            <param-name>replace</param-name>
            <param-value>https://www.mysite.com:8443/myapp/images/logo/alfresco_community_logo.gif</param-value>
         </init-param>
    </filter>
‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Note: "myapp" is a dummy/non-alfresco application that is also served by the Alfresco Tomcat web container. This provides a place to store the image outside of Alfresco. It might also be possible to store the image w/in the Alfresco app tree, but I chose this location instead. I copied the Alfresco Community image from the Alfresco site to the specified directory on my local server and renamed it to the specified name (see above).

4. Next, after the other filter definitions in the web.xml file, I added the following filter mappings to invoke the filter at the appropriate times (on all '/alfresco/navigate' and all '/alfresco/faces' pages):

 
    <filter-mapping>
        <filter-name>Replace Text Filter</filter-name>
        <url-pattern>/navigate/*</url-pattern>
    </filter-mapping>
    <filter-mapping>
        <filter-name>Replace Text Filter</filter-name>
        <url-pattern>/faces/*</url-pattern>
    </filter-mapping>‍‍‍‍‍‍‍‍‍

5. I restarted the Alfresco app, and voila, the non-ssl url's to Alfresco's home page were replaced, on-the-fly, with mappings to the image stored on the local server.

This should be considered a work-around only, as the filtering search-and-replace operations consume resources on every page reference. When the Alfresco team fixes this in a later release (assuming they do…), this filtering hack should be removed.

mrudmann — Wed, 07 Feb 2007 16:03:54 GMT

Thanks for the tip.

I applied the filter mentioned above. I set my filter up to replace the http image with an https image on my server (and within the alfresco tomcat environment).

It partially worked. I no longer get the "nag" screen asking if I want to display nonsecure items, but the image is not successfully replaced (I see that image indicating the graphic can't be displayed/found, etc., but I know the image is there). Again, I am trying to point to an image within my secure alfresco/tomcat environment.

Any thoughts for me? I am trying to avoid running Apache as I don't really see a need for it at this time.

Thanks!

1. Where does the server "think" the image is stored? You can find this out by right-clicking on the image, selecting the "Properties" option, and looking at the location information in the resulting pop-up.

2. Where is the image actually stored? As I stated in the original post, I believe I stored my image in a Tomcat sister application to the one used by Alfresco. In other words, under my $ALFRESCO_HOME/tomcat/webapps there are two sub-directories, one for the Alfresco application (…/webapps/alfresco) and one that I used for the image storage (…/webapps/myimages - or whatever app name you want to use). My primary reason for storing the replacement image outside Alfresco was to keep the Alfresco distribution in synch with the "standard" download. But I also believe that files stored under the Alfresco application may not be directly accessible due to the navigation services that Alfresco uses to intercept and redirect URLs that point into the Alfresco application. So, to make this work, you may have to create this sister application/directory structure.

If you can report the data for these two items, I can look for anything obvious (or, maybe, not so obvious…).

Re: disable external image for https

mrudmann — Wed, 07 Feb 2007 19:23:55 GMT

Dave,
I created a directory as follows:ALFRESCO_HOME/tomcat/webapps/myimages. within this directory, I placed the alfresco logo image. then, in the web.xml file, I coded the location https://192.x.x.x:8443/myimages/alfrescologo.gif as the parameter to replace the http logo (per your example).

When I right click and select properties, my image indicates it is looking at https://192.x.x.x:8443/myimages/alfrescologo.gif for the image - which is where I placed it.

I see the "X" image instead of the alfresco logo.

Any feedback is greatly appreciated!

-Matt

Perhaps this is a permissions problem…Can you check the permissions on the image and the directory in which it's stored? Make sure the image and containing directory have the same group/owner as the other Alfresco directories/files and the appropriate permissions to enable the Alfresco/Tomcat server to access them.

Re: disable external image for https

mrudmann — Thu, 08 Feb 2007 21:30:53 GMT

I would like to report back SUCCESS!

After making the filter changes per your suggestion above, I placed the alfresco graphic in the TOMCAT_HOME/webapps/alfresco folder. It worked like a charm!

I am now able to run Alfresco under SSL without the annoying nag screen from the graphic and I didn't have to recompile the entire application. What a simple solution.

Thanks for your help, Dave!
