Peter Diefenthäler commented on WICKET-2567:
--------------------------------------------
As I stated above we have 700 open file handles in production this time. If the
system will be used by more users in the next months we don't know, how often
the garbage collector has to do its job. This is alos a performance risk,
because our application is not the only one on this server and garbage
collection affects all other apps also.
Second point is that we have this problem on IBM WebSphere and on Oracle
Weblogic Servers. Its not only a weirdness of the IBM JRE but I think its a
weirdness of the big application servers which use proprietary mechanisms to
achieve better scalability and performance.
Unfortunately our big customers use IBM and Oracle servers, so we have to solve
this problem ...

> Key: WICKET-2567
> URL: https://issues.apache.org/jira/browse/WICKET-2567
> Project: Wicket
> Issue Type: Bug
> Components: wicket
> Affects Versions: 1.4.3
> Environment: The problem exists on IBM WebSphere 6.1.0.19 running on
> Windows 2003 Server
> Reporter: Peter Diefenthäler
> Assignee: Johan Compagner
> Fix For: 1.4.4
>
> Attachments: FhTest.war, Open File Handles on WebShpere for Wicket
> Application.jpg
>
>
> Running Wicket applications on IBM WebSphere and Oracle BEA application
> server result in a huge amount of open file handles for images and
> stylesheets. Our customer has up to 700 open file handles up to 50 file
> handles on the same stylesheet or image.
> The stylesheets are directly referenced in the HTML files:
> <html>
> <head>
> <title>PTS/A&R Login</title>
> <link rel="stylesheet" type="text/css" href="styles/basicStyles.css" />
> or
> <html>
> <wicket:head>
> <link rel="stylesheet" type="text/css"
> href="styles/genericMaint.css">
> </wicket:head>
> <body>
> <wicket:extend>
> <div wicket:id="genDetail"/>
> </wicket:extend>
> </body>
> </html>
> Sometimes the images are referenced within the stylesheets:
> .mainLogo {
> position: relative;
> top: 0px;
> left: 0px;
> width: 188px;
> height: 35px;
> background-image: url(../images/AARLogo.png);
> }
> But in most cases we use the images directly in the HTML code.
