RE: conversion of turbine app to portlet?

[Phillip Rhodes]

A lot of work would have to be to get WebPagePortlet to work well.  Namely 
adding cookie support.

Although I could do this, I wonder if this is the best approach for 
integrating java servlet based applications into portal...

Is there anyone working on WebPagePortlet to make it be able to do the cookies?

Re: Question about portlet caching policy

YM,
I am working on changes to the cache subsystem.  These changes will 
allow portlets to refresh their content.  In addition their will be some

Question about portlet caching policy

[Yellow Man]

I have a question about refreshing the portlets cache.
The refresh interval is defined in Jetspeed.properties
by "refresh.portlet.default". This interval applies to
all portlets. If you want to tune the refresh interval
for individual portlet, you have to write your own
portlet class with customized isCacheable() and
expire() methods. Am I right? 

If my understanding is right, wouldn't it be easy to
tune the caching policy for individual portlet if we
add a new tag in  in the registry for
defining the caching policy?

Thanks!

RE: conversion of turbine app to portlet?

[David Sean Taylor]

Try the "WebPagePortlet" -- see the example in the portlet registry
"demo-portlets", and the portlet named: "JavaWeb"

For the simplest solution, I recommend running it in another webapp, since
you will most likely have conflicting versions of turbine or velocity jars.

Re:WebPagePortlet problems - Solved

[Brendan O'Bra]

It's luck only that I finally figured  this out...

This was an AWT problem (?!), and had nothing to do with org.apache.*

I'm running debian potato 2.2.  As this is a production system., X is not
installed.  I had to intall xlib6g, and now everything is fixed!

Thanks for all the effort everyone!

conversion of turbine app to portlet?

[Phillip Rhodes]

Hi,

I wrote a application in Turbine using the TDK (2.1)  with JSP's

Can someone point me how I may create a portlet for this?  In the 
AbstractPortlet, I have to implement the getContent (RunData runData) 
method.  Should I write a reverse http listener here that talks to the web 
front end of my application, or is there something lower that I should be 
communicating with?

I am a little confused.  Would you recommend that this application reside 
in the same JVM as the portal, or should be in a different tomcat instance, 
or maybe even a different web application (in the servlet container)

Thanks,
Phillip

It was no spammer who sent it, but someone subscribed to the list which 
got infected.

I don't think there is an antivirus mail filter in apache.org. There 
used to be a no attachment policy, but it has changed.

Unless you have a badly designed and/or badly configured mail client, no 
email message can make you harm if you stick to a single rule:

- never open an executable attachment (not even apparently coming a from 
trusted persons). This includes disabling javascript or other client 
side scripting languages in HTML mail.

Unfortunately, Outlook is very badly engineered and also very badly 
configured by default, so I think this statement does not include it.

Commenting on myself ;), I found that it was set in the Layout and the 
TemplateLocator, about six times per page, when it should be put in the 
Page just once. I don't have it clean yet, but I'm getting closer.

I do not know :(

Their are cache settings on the browser.  These settings may be causing
a reload on refresh when the page is < 60 seconds old.

The setting in the HTML header should take precedence over META tags.

Hmm. I wonder how http.lifetime != 0 forces a browser to switch encodings?
I just set it to 60 seconds and it still asks me to reload the page. :-((

   New E-mail Worm Is No Party, Virus-Fighters Say
  
   Anti-virus companies say a new e-mail worm they have   
   named "Myparty" won't be much fun for PC users who launch  
   the malicious code after clicking on what they think is a  
   link to a page on the Yahoo Web site.  
  
   Researchers at Moscow-based Kaspersky Labs said today  
   that the code behind the Myparty worm, written for the 
   Windows operating system, isn't particularly unusual,  
   including its ability to open a backdoor in some versions  
   of Windows that could then be exploited by hackers.
  
  

  
  
  
  
  
  


   
   
   
   
   However, Kaspersky spokesman Denis Zenkin said, the virus author's decision to name 
his executable file like a Web URL - "www.myparty.yahoo.com"   
   - appears to be fooling many Internet users who are finding the file linked to 
e-mail messages.
   
   
   "The rest of the program is a classic Internet worm that is not differentiated from 
hundreds of similarly created Internet worms," Zenkin said in  
   a prepared statement. "This occurrence once again confirms that not everything 
beginning with 'www' and ending in '.com' is a Web site."   
   
   
   Symantec Corp.'s Security Response team has already given Myparty a severity rating 
of 3 on a scale of 1 to 5, largely because of the potential
   for the worm to spread rapidly. 
   
   
   
   Cupertino, Calif.-based Symantec said Myparty arrives attached to an e-mail that 
will have the subject: "new photos from my party!"
   
   
   The text of the message reads: "Hello! My party ... it was absolutely amazing! I 
have attached my web page with new photos! If you can please  
   make color prints of my photos. Thanks!"
   
   
   
   Kaspersky Labs said that, at first glance, the e-mail's link to the 
"www.myparty.yahoo.com" file might look like a Web-site URL, even to users 
   who know better than to click on executable attachments.
   
   
   
   Kaspersky reported that Myparty appears to be programmed to spread only between the 
dates of Jan. 25-2

IllegalAccessException & PortletException: questions

[Michel Bergijk]

Hi all,

Being new in portals, I do not know what to do with the Exceptions
IllegalAccessException & PortletException.

I have looked in the JavaDocs what these exceptions mean, but can not get
any information how to solve this problem. 
PortletException: Occurs when anything unexpected happens when processing a
Portlet. 
IllegalAccessException: Thrown if an application attempts to access or
modify a field, or to call a method that it does not have access to. 

What did I do?
Created a Portlet, with (an excerpt from my) code:
public ConcreteElement getContent (RunData runData)
{
user = new User();
openWriter(); // Michel: My own brand of logger, it did not
work.
writer.println ("CompanyList.ConcreteElement: creating
order");
order = new Order(writer);
StringElement quote = new StringElement();
return (new StringElement (getCompanyList () ) );
}

I compiled this porlet, and copied the resulting class files to 
C:\Apache\tomcat\webapps\jetspeed\WEB-INF\classes

Next I added the following lines to portlets.xreg and local-portlets.xreg:


Company list
Gets the company list from SAP IDES

CompanyList



This method worked for the normal HelloWorld and HelloUser portlets.

My questions:
1 Does anyone know what I need to do to get information about these
Exceptions?
2 What did I do wrong, given my code snippets?
