Communicating between 2 portlets on a page
Hi,
I am new to portals and would like to know if there is a way that we can
communicate between 2 different Portlets on the same page. What I mean
to ask is, if I have 2 different portlets on a page and I do some action
in one portlet then I want to communicate it to the second portlet on
the page and display some information on it based on the action in the
first portlet.
Thanks much,
Vijay Aalati

Error generating portlet: error building POM

Today, while generating a simple portlet archetype, I got fatal error (on
below). This task worked earlier without any problems, what might be wrong?

Hi,
Yes, it's possible between portlets that are in the same "portlet
application" (thanks to 'Attributes' from 'PortletSession' object):
* one portlet publish the object you want using:
/request.getPortletSession().setAttribute(String att_name,
Object att_value, *PortletSession.APPLICATION_SCOPE*);
/
* any other portlet in the application can retrieve that object using:
/Object o = (Object)
request.getPortletSession().getAttribute(String att_name,*
PortletSession.APPLICATION_SCOPE*);
/
Hope that helps.
Regards.

Elif,
Thanks for the link! Yes, I have gone through it. I was also looking at
something called PortletMessaging class. I have not yet gone through it
though.
Thanks,
Vijay

Hi,
another thing I stumbled into: when I compile the tests for JVM 1.5 it
fails because at some points the variables are called "enum", which is not
allowed anymore for 1.5..

Ok, I actually downloaded it manually because I saw that it wasn't
present; I guess it now would have worked!
As a note: the "maven war" command fails on windows platforms if the
filename starts with "Documents and settings\...", I think because of the
space... When I move it all to a directory without spaces it works fine.

jetspeed 1 trunk build
Posted by b....@valbosoft.com.
Hello,
I'm building jetspeed 1 trunk, but when I execute maven war it seems to
have a problem downloading spring-1.1.5
I've tried to extend maven.repo.remote in the project.properties file:
maven.repo.remote =
http://www.bluesunrise.com/maven/,http://www.ibiblio.org/maven/,
http://dist.codehaus.org/, http://cvs.apache.org/repository,
http://mirrors.ibiblio.org/pub/mirrors/maven
but maven doesn't seem to use it:
Intentando descargar spring-1.1.5.jar.
Error retrieving artifact from [
http://www.ibiblio.org/maven/springframework/ja
rs/spring-1.1.5.jar]: java.io.IOException: Unknown error downloading;
status cod
e was: 301
Error retrieving artifact from [
http://cvs.apache.org/repository/springframewor
k/jars/spring-1.1.5.jar]: java.io.IOException: Unknown error downloading;
status
code was: 302
íATENCION!: íImposible descargar spring-1.1.5.jar!
Any suggestions on how I can make maven look at the right place?
