JRE problem

[Thiago Kleinubing]

Hi,

i'm trying to use HttpClient 2.0 Library to communicate one applet to one webserver, 
but i'm having some troubles.
Every time when the applet is loaded the exception is shown:

java.lang.VerifyError: (class: AppTeste, method: init signature: ()V) Incompatible 
object argument for function call
 at java.lang.Class.newInstance0(Native Method)
 at java.lang.Class.newInstance(Unknown Source)
 at sun.applet.AppletPanel.createApplet(Unknown Source)
 at sun.plugin.AppletViewer.createApplet(Unknown Source)
 at sun.applet.AppletPanel.runLoader(Unknown Source)
 at sun.applet.AppletPanel.run(Unknown Source)
 at java.lang.Thread.run(Unknown Source)

I' ve already tried to run the same code in command line and the same problem happened 
again. When i changed de JRE from 1.3.1_06 to 1.4 the problem DIDN'T occur. It seems 
to me a class loader problem, PLEASE can anyone help me??????

Thank's 
Thiago

Hi Oleg,

First, thanks for your response. I´m actualy using with 
MultiThreadedConnectionManager, but when i change to MultiThreadedConnectionManager 
the connections timeout has decreased a lot. With MultiThreadedConnectionManager 
appears greater than SimpleHttpConnectionManager. It´s correct or i´m wrong?

I want to understand the MultiThreadedConnectionManager. Can 
MultiThreadedConnectionManager do what i want ? Can it manage a set of connections ? 
If yes, where can i find an example ?

Thanks very much. 

Waiting for response,

Thiago Costa

Dear Friends,

I'm using the HTTP Client in a pool of connection. I have created a 
class that manage a list of URL. For example: i have a list of 100 URLs 
of diferent hosts. I want to retrieve all this urls but i don't want 
to do this in a sequencial mode. I want to put  some connections in a 
paralel mode. Like for example... I want 10 connection in paralel... 
Then, when a connection finish an other starts. I want to use this in a 
meta engine to retrive documents in Web.

My problem is that httpclient is raising many exeptions of connection 
timeout. I'm running my application in  super fast internet provider 
and it's not normal these time outs.

Does the httpclient manage a pool of connection like that ?
Does httpclient works well in a multithead mode ? How can i manage a 
list of url with a great performance ?

Can you help-me?

Thanks very much
