Request missing 'ice.session' required parameter. Dropping connection

You are using icefaces version 1.8.0 and have this problem?
The solution is, just upgrade to version 1.8.1 because this is a bug...

It would be great if all problems could be solved like this ;-)

How to get running the icefaces portlet samples with liferay?

The icefaces distribution includes many samples and the both portlet samples location and chat. You need to have installed ant to be able to build them.
You can find these examples in [ICEFaces-xxx-bin]/icefaces/samples/portlet.
To use them in liferay - I tested it with the version 5.2.2 - you need to change a small thing in both of them.
For the location-portlet you need to add in location/conf/web.sunri.icefaces.xml
the following entry

<context-param>
<param-name>com.icesoft.faces.compressResources</param-name>
<param-value>false</param-value>
</context-param>

And then you can build this portlet with ant and it should run in liferay.

For the chat-portlet you have to change the entry in chat/conf/web.sunri.icefaces.xml
from

<context-param>
<param-name>com.icesoft.faces.compressResources</param-name>
<param-value>true</param-value>
</context-param>

to

<context-param>
<param-name>com.icesoft.faces.compressResources</param-name>
<param-value>false</param-value>
</context-param>

Then build it with ant.

Have fun ;-)
