param in request

[jacky <ja...@gmail.com>]

hi,
  I added a link in  jsp
<a href="http://localhost:8080/pluto/portal/helloword?titleId=1600630">test
link </a>

but in portlet, the param titleId can't be retrieved by
request.getParamter("titleId").  result is null.
 how can i get the param in portlet?

  Best Regards.

Hi jacky

I'm no expert but I think your making a plain GET param that the 
Portal/Portlet Container in principle do not know what portlet it 
belongs to. You should do something like:

<portlet:renderURL var="myViewUrlWithParam">
  <portlet:param name="titleId" value="1600630" />
 </portlet:renderURL>

and then

<a href="${myViewUrlWithParam}">Go get it</a>.

Have a look at how the portlet container inserts this in the URL.

Try and have a look at the specification it's not that hard a read. I 
"PLT.7.1 PortletURL" it says:

<quote>
Because some portal/portlet-containers implementations may encode 
internal state as part
of the URL query string, portlet developers should not code forms using 
the HTTP GET
method.
</quote>

Thinking about it now I'll say that the point is that with portlets you 
have to 'generate' urls (for view og action) which is very different 
from normal webapps.
