[Lift] InputStream to String
I have seen this problem around and it seems basic but I haven't found
a solution. I need to turn an InputStream into a String. There seems
to be a bug in the Source class that fails for large files so I don't
want to use that (though it is an elegant approach).
The following doesn't work because reader.readLine returns Unit and
not null, as in Java.
val reader = new BufferedReader(new InputStreamReader(is))
var responseBody = ""
var line = reader.readLine()
while(line != null){
responseBody += line
line = reader.readLine()
}
return responseBody
What to do?

[Lift] Comet Actor
I have a some code in a CometActor that I want to run right after render is called for the first time. What is the best way to do this? I could set a boolean variable in the render method and then send a message back to the CometActor to tell it to run the code. I suspect there is a better way? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Lift" group.

[Lift] CometListener
I am trying to use CometListener. According to http://bit.ly/1Wnxt4 , it is in the package net.liftweb._ but compiler says it can't be found.

Is it that I am putting things on a Queue from within an the Calculator Actor and having the CometActor retrieve them from the Queue? Is that the problem? I will read up on actors but it would help if you could tell me (if only briefly) what you saw about my actor code that is wrong. Thanks.

Will do. One more small question How do I send a message to the Comet Actor from another class? Can the CometActor be an object instead of a class? In the code X ! messageToCometActor, what is X? I don't have a variable that holds the instance of the CometActor. On Thu, Nov 12, 2009 at 5:12 PM, David Pollak wrote: > Jack, > > The issues you're seeing are not Lift related.

one more thing: I also ran the code without the piece that retrieves web pages and gets their length. Instead I just had the Calculator class sleep for 10 seconds (which is longer than the http request takes) and then return a random number. This worked fine. I can't see what the difference is.

Sorry. Just reread my past post and it is indeed unclear. I will post
running code tonight. I very much appreciate your help.

[Lift] Re: CometActor and render
The only difference between your working code and mine is that mine has a
process in the background that is always running and puts Foo objects on a
queue whenever they are ready. Where can I start this long running process
so that it doesn't interfere with the lowPriority method that takes things
off the queue and rerenders the page. I tried starting the process in its
own Actor that I start in localSetup but it seems somehow to be blocking the
lowPriority method from doing its thing.

[Lift] using Dispatch library for Http
I'm using the Dispatch Databinder library for Http. http://bit.ly/NPWcW
My code is this simple method.
def testCheckPage(url:String):String = {
try {
var http = new Http
var request = new Request
(url)
val req_with_agent = request <:< Map("User-Agent" -> "Mozilla/
5.0")
val responseBody = Http (req_with_agent as_str)
responseBody.length.toString
} catch {
case ex: Exception => {
"Message: " + ex.getMessage
}
}
}
For some urls, e.g., http://bae.cf.huffingtonpost.com/ , an exception
is thrown but the exception message is null. Any ideas?

Oops. I just noticed I made source.body a String and not a NodeSeq.
Sometimes source.body is text with html tags in it. Like -
Hey dude, what are you doing?
I guess I should make it a NodeSeq. Sorry about that.

Let's say source.body is Search. If I put

source.body will be converted to text and the actual link tags will be

I have the following method display. source.body has html tags in it

This method is in a CometActor and is running when the page is

[Lift] Naming CometActors
So if give a CometActor a static name, say "Other", then every request will get the same running instance of the CometActor. But if I name it dynamically, say with a random string, each request will get its own instance of the CometActor.

[Lift] Re: Help!
Thanks David. The command I was trying to remember was deploy-war but I kept using run-war. The names are not quite precise. run-war should be called build-and-run-war, and deploy-war is really run-with-war. If those names were not so horribly long, that is.

[Lift] Re: execute code when browser is closed
I didn't mean to sound like I am justifying the way I am doing. I definitely
do not have a good feel for lift yet and it feels hackey to me too. Part of
it is I'm rushing to get a demo done at the same time I am learning lift.
Thanks for your help.

[Lift] Re: execute code when browser is closed
So I am using a snippet like this
def go:NodeSeq = {
var term:String = S.param("term").openOr("")
}
And the term is indeed different each time. But I am still getting the same
results from two different browsers with different terms.

[Lift] Re: execute code when browser is closed
Let me start again. Maybe I am misunderstanding when Comet should be
used. In my application, people search for web pages. I do a lot of
processing for each resulting page. First I just display the links and
then as the processing is finished, the links on the page are
automatically modified with the data I just found for each link. This
is all working fine.
But, the session is being shared among all users so if I make one
search in one browser, and then make another search from another
browser, I get the results from the first browser.
David suggested I name each CometActor differently. That is not
working, though maybe I am not doing it right.

[Lift] Re: execute code when browser is closed
Good. Only thing is that if their job was to start an actor to go out and search some pages, say, then 'stop your job' means ' 'call your 'exit' method, no?Not trying to be a wise guy. I actually have a number of VCs lined up to look at my app. Overall I am very glad to be using Lift. On the Comet alone it save me a LOT of time. Of course, I have a lot to learn.

Because when the users searches on a new keyword, the actors that were processing the results for the last keyword are still processing (some of them). But I can just send each of those a message to stop processing, no? No problem with that, right?

In my app, when the user is done searching on one keyword, they click a link which takes them back to the main search page. Thats the time when I wanted the CometActor to stop. Otherwise there will be too many threads floating around and performance will suffer.

[Lift] Re: execute code when browser is closed
Interesting. I will try that. And I won't send any more ShutDownMessages :) Though I should add that each CometActor is doing a lot of processing. So I it would be good if I could shut one down somehow when the user searches on a new term. Timeout won't work because there is no way to know how long it will take. Maybe I could just kill all the actors directly that are doing the processing.

[Lift] Re: execute code when browser is closed
Understood. My intention is to send a ShutDown message to the CometActor when somebody closes the browser. I need this so that when they visit the page in a browser again, the CometActor is 'reset'.

[Lift] Re: a very simple question
Well my app is a search application. You search for certain web pages and I
do some processing after the results are displayed. Thats why I am using
Comet. Certain information is added to each result link.
I want the user to be able to either hit the back button or click on alink
that goes to the search page again. When they enter a search term and click
submit, I want to load the CometActor class again.
Do you think sending a ShutDown message will accomplish this?
After the session is killed, how do I get the CometActor to automatically
load again. Do I send the message and then redirect to the page?
I am just not comfortable yet with the mechanics of how Lift handles comet.
Thanks in advance.
Jack
