how to dowload youtubevideo's using java

Can you please be a bit more specific? As you're posting this question in a JSP forum, I assume that you want to embed those videos in your JSP page? If so, you can just use HTML for that. The exact HTML is usually available for copypaste at the youtube page of the desired video.

Opening an excel file on server side using servlets

hi, am having a small problem for launching an excel file. Standalone,
i use
Desktop.getDesktop().open( new File("C:/test.xls") );
and it works fine but when using servlets via tomcat, it does not launch. Any idea?
actually am using ajax to allow a user to remotely launch an excel
file (the excel file contains a macro which will generate and save a
chart as image) on the server.

Do you realize that this will only open that Excel file at the Server machine, not at the Client machine? If you're testing (read: acting as Client) at the same machine as where the Server runs, then you will see the result of Desktop#open(). But if you're testing at a different machine (read: as in the real world) than where the Server runs, then you won't see the result of Desktop#open(), because this is executed at the Server machine itself, not at the Client machine.

How to access serial port using servlet

I want to communicate with a microcontroller connected to the serial port of my computer.
*I am using the following:
Windows 98 operating system
Tomcat web server 4.1
*The directory structure is as given:
Tomcat 4.1/webapps/myjsp/web-inf/classes/remoteservlets.
I have placed my jsp files in my jsp folder and classfiles in remote servlets folder.
**my java program has compiled correctly.**
** my simple java application which accesses the serial port works fine.***
*when I start tomcat I am able to access the sevlet as the servlet responds with the button name i have pressed.
**** I have also tried the following
Copied file comm.jar in <JAVA_HOME>\jre\lib\ext
Copied file javax.comm.properties in <JAVA_HOME>\jre\lib
Copied file win32com.dll in <JAVA_HOME>\lib and also in c:\windows\system32 and c:\windows\system
***************which helped me do away with errors.
still I don't get any output. I dont get any errors either.
PLEASE HELP. URGENT. i am at my wits end.
Thank you.

Servlet is the one which runs in the server side...if u want to comunicate with the serial port of the server in which ur servlet is running can be done but making use of Communication api available....
U can download the Api from http://java.sun.com/products/javacomm/index.jsp
There are three levels of classes in the Java communications API:
High-level classes like CommPortIdentifier and CommPort manage access and ownership of communication ports.
Low-level classes like SerialPort and ParallelPort provide an interface to physical communications ports. The current release of the Java communications API enables access to serial (RS-232) and parallel (IEEE 1284) ports.
Driver-level classes provide an interface between the low-level classes and the underlying operating system. Driver-level classes are part of the implementation but not the Java communications API. They should not be used by application programmers.

How to disable client cookie using Servlet code

Hi All,
          I want to disable the client cookie using JSP or servlet code.Is it possible how I can do it.
          Thanks in Advance .

Hi,
          first of all, the URL rewriting option (URLRewritingEnabled) in the weblogic.xml must be set to true.
          Now, for all first-timer web requests the BEA WLS always uses URL rewriting in addition to cookies to see wether the browser accepts cookies or not.
          I would try to rip of all of the cookies in the header, then flush the response to force the http header to be written.
          I have never tried it and has no idea if it will work, however the teory behind supports the idea.
          This will not work for toggling session tracking mechanism from a session already established with cookies, the session will be lost if attempted to do this without the URL-rewriting enabled on the page.
          - Anders M.

How-to: Not having to use '/servlet' in URL

All,
How would I go about modifying Tomcat so that I wouldn't have to use .../servlet... in the URL?
eg.
current:
http://myhost/servlet/loginServlet
configure to:
http://myhost/sBin/loginServlet
sBin (just an example) can be any other name
Is this possible?
Thanks.

in your .webapp file, change the value of the
<servlet-path> parameters to what you want it to be. i.e.
in default-app.webapp we find:
<servlet>
<name>snoop</name>
<description>snoop servlet</description>
<code>SnoopServlet</code>
<servlet-path>/servlet/snoop/*</servlet-path>
<servlet-path>/servlet/snoop2/*</servlet-path>
<init-parameter>
<name>param1</name>
<value>test-value1</value>
</init-parameter>
<autostart>false</autostart>
</servlet>
change /servlet/snoop/* to /sBin/snoop/* et al.

How to create crystal reports using servlets/jsp

plase any body help me how to create and interact with crystal reports using java

To use the inproc RAS SDK with CR.NET, you'd have to purchase either (1) Crystal Reports XI Release 2 Developer edition, and apply Service Pack 2 or above, or (2) Crystal Reports 2008 (not Crystal Reports Basic that comes with Visual Studio 2008).

How to create Tab pages using servlet

I want to create a tab pages which can carry different pages. Can you help me on this?? Provided if you have some guideline or program which can help me.
Thanks

those kinda tab pages should be coded :) there is no built-in support for them!
like BalusC wrote you better sould export the layout into CSS, then, you have the option of using javascript when switching between tabs.
if you want to avoid using of javascript or you want to do it serverside, then you'll have to write that tab handling in your jsp page
