"This portlet is not available": on first run of login portlet

[wimbi...@telenet.be]

Hello,<br />
<br />
I have a problem each time I restart my WPS 5.1.<br />
<br />
To access the portal, I am using a index.html with a frameset showing the wps/myportal page. The first thing shown in wps/myportal is the login portlet.<br />
<br />
Each time I restart my portal and access the login portlet for the first time, the error message "This portlet is not available" is shown. <br />
The problem can be solved by accessing the /wps/portal page, after that, the portlet on the index.html works fine. <br />
So to me this just sounds like a problem with initialising the login portlet. The (shortened) stacktrace from the wps.log are listed below, they are not really telling me a lot.<br />
Please let me know if somebody had this problem before.<br />
<br />
Thanks,<br />
<br />
Wim<br />

Did you do any customizations? Usually, " NO Portlet available " comes when the custom code logic is somewhere wrong as far as I know.<br />
<br />
May be there can be some other mistake too.

[wimbi...@telenet.be]

There is one servlet filter on the portal, but that shouldn't have any impact.<br />
<br />
What kind of code logic specifications are you talking about exactly?<br />

The problem seems to be this URL:
'http://staa168l.lu.fortis.bank/wps/portal/!ut/p/.scr/Login'
This seems to be an invalid URL, therefore you get the exception you
pasted in your post. Where does this URL come from? Is this from your
index.html file?

Sorry, I thought that you have developed some custom portlet where generally that error msg(Portlet Unavailable) on the screen will come if our code logic goes wrong. <br />
<br />
Anyways, it seems that similar problem has occured to few in 5.1 Version.<br />
