Question: ASP vs. JSP?
Answer: Comparing JSP with ASP
Although the features offered by JSP may
seem similar to that offered by Microsoft's Active Server Pages (ASP), they are
fundamentally different technologies, as shown by the following table:
||Most popular web
servers including Apache, Netscape, and Microsoft IIS can be easily enabled with
||Native support only
within Microsoft IIS or Personal Web Server. Support for select servers using
Runs on all Java-enabled platforms.
||Is fully supported
under Windows. Deployment on other platforms is cumbersome due to reliance on
the Win32-based component model.|
||Relies on reusable,
cross-platform components like JavaBeans, Enterprise JavaBeans, and custom tag
||Uses the Win32-based
COM component model.|

JScript for scripting.|

Windows NT security architecture.|

|Check for Internet Connection
In order to
create a WildTangent-Intranet-Site, i want to check if my Server is connected to
the WorldWideWeb or not via Java. The solution has to return only TRUE or FALSE!
It must not open a window, cause an error or anything else that avoids a
discrete check. It has to be just a stealth check.
|Swing and IE jvm
I'm writing an
applet in Swing, because it contains some nice controls (like JSpinner, JCombo,
etc.). The only problem is that this does not seem to be compatible with the
built-in JVM of Internet Explorer.
There is of course a way to get IE
download the "java plug-in", but this is not quite practical for me, as it
downloads the whole JRE and installs it on the machine.
Does anybody knwo of
a way to compile a Swing applet so that it is compatible with the built-in JVM
of IE (say as of IE5)?
Thanks for your help! Eric.
|Problems with EventQueue and Modal Dialogs
Hi, I have a problem as
What we did was to follow a Tech Tip, which can be found in
It automatically shows an hourglass cursor, when an event call does not
return within a specified time (delay). It worked ok at the beginning BUT;
The problem is, the code gets the system event queue like
and pushes another event queue instead of
this one. The new queue is an instance of a WaitEventQueue class, which is very
simple infact and does what I wrote above.
After this new queue is
|Multiple Selection Drag n Drop w/ JTree
Has anyone here
implementing Multiple Selection Drag and Drop with JTrees? I know that there was
a bug in JDK 1.3 that wouldn't allow it but I think that it would've been fixed
in 1.4. So far I've implemented Single-Selection DnD but I don't know how to get
Multiple Selection working.
I know that the tree has to be set in either
DISCONTIGUOUS_TREE_SELECTION or CONTIGUOUS_TREE_SELECTION, but I am unable to
drag the nodes. How can I change my Single selection DragSourceListener and
DropTargetListener so that it implements Multiple Selection?
|Changing file attributes
Does anybody know how to change
file attributes such as read and write in Java.
