How to invoke java class automatically at a fixed time everyday

How to invoke a java class automatically using Quartz scheduler or any other simplified way
I am trying to schedule a job in my web application and need to understand conceptually How to make it work using quartz . The job is scheduled to be executed at 4 pm daily. Am testing the same and It works well when i run it as standalone application manually.
How to configure it that when i start my aplication it should run at its own through quartz.
I am avoiding use of servlet init method and java timer though any alternatives there?
Thanks for your help.

I've not see quartz... are you in Windows, Solaris, Linux, or Mac?
Are you using JAR files or class files?
Windows: javaw myClass (I cannot remember right off if you have to have the .class on the end)
Windows: java -jar myJAR.jar
Solaris java -jar myJAR.jar
Linux java -jar myJAR.jar
Mac?

How do you set a calendar alarm for a specific time on the day of the event without it being an all-day event

Does anyone know how to set a calendar alert at a specific time on the day of the event.
So that the alert date adjusts accordingly if you were to copy and past it to another date.
The custom alert function kind of does this, but because it is an absolute alert (not relative) it will still refer to the date you initially set it to when you copy and paste it to another date. So this creates more work where you would have to go and manually change all the custom alerts. I have potential
Anyone know how to set this kind of calendar alert?
Thanks in advance

Greetings: Set the alarm to message you (on your screen) and then snooze it every day for 15 days, or, set 15 separate alarm messages. There is probably an AppleScript somewhere on the web too, try searching that way as well.

How to load a .class file dynamically?

Hello World ;)
Does anyone know, how I can create an object of a class, that was compiled during the runtime?
The facts:
- The user puts a grammar in. Saved to file. ANTLR generates Scanner and Parser (Java Code .java)
- I compile these file, so XYScanner.class and XYParser.class are available.
- Now I want to create an object of XYScanner (the classnames are not fixed, but I know the filename). I tried to call the constructor of XYScanner (using reflection) but nothing works and now I am really despaired!
Isn't there any way to instantiate the class in a way like
Class c = Class.forName("/home/mark/XYScanner");
c scan = new c("input.txt");
The normal call would be:
XYLexer lex = new XYLexer(new ANTLRFileStream("input.txt"));The problem using reflection is now that the parameter is a ANTLRFileStream, not only an Integer, as in this example shown:
Class cls = Class.forName("method2");
Class partypes[] = new Class[2];
partypes[0] = Integer.TYPE;
partypes[1] = Integer.TYPE;
Method meth = cls.getMethod("add", partypes);
method2 methobj = new method2();
Object arglist[] = new Object[2];
arglist[0] = new Integer(37);
arglist[1] = new Integer(47);
Object retobj = meth.invoke(methobj, arglist);
Integer retval = (Integer)retobj;
System.out.println(retval.intValue());Has anyone an idea? Thanks for each comment in advance!!!

Dump all of your class files into a directory.
Use the File class to list all files and iterateover
the files.NastyNot really, when you are dynamically creating code, I would expect the output to be centralized, not spread out all over the place.
>
Use a URLClassloader to load the URL that isobtained
for each file with file.toURI().toURL()(file.toURL()
is depricated in 1.6)Wrong, the URL you give it must be that of the
directory, not the class file.No, I did this quite recently, you can give it a specific class file to load.
>
Load all of the classes in this directory, thatway
any anonymous classes are loaded as well.Anonymous classes automatically loaded when the real
one isIt can't load it if it doesn't know where the code is. Since you haven't used a URL classloader to load once class file at a time, you would never encounter this. But if you loaded a class file that had an anonymous classfile it needed, would it know where to look for it?
>
From this point you should be able to just get a
class with Class.forName(name)No. Class.forName uses the classloader of the class
it's called in, which will be the system classloader.
It won't find classes loaded by a URLClassLoader.got me there.

How to convert a class file to exe file and how to cteate a class file to d

how to convert a class file to exe file

Hi Bhaskarq,
Hi,
It is not at all possible.
But it is a really worst method.
Please go through it.
This is a very common question asked in the comp.lang.java newsgroup. Its often useful to have an
executable application when deploying your
applications to a specific platform, but remember to
make your .class files available for users running
Unix/Macintosh/other platforms.
Microsoft provide a free system development kit (SDK),
for Java, which includes the jexegen tool. This
will convert class files into a .EXE form. The only
disadvantage is that users need a Microsoft Java
Virtual Machine (JVM) installed. If your target
platform is Win32, you can either redistribute the
virtual
machine, or raise the level of your system
requirements, to include Windows 98, or Windows 95
with
Internet Explorer 4. Systems matching these
requirements will already have a copy of the Microsoft
Java Virtual Machine installed.
Note : You must specify all of the class files your
application needs (except for standard java packges)
as a parameter, so if you have third party libraries,
you'll need to include them as well. You can use wildcards * though, and you don't need the original source code.
Also please see this Forum which will give a good idea

I hope this will help you.

How to include a .class file in a jsp page

hi everyone,
i know the syntax as:
<%@ include file = "filename.class" %>
then at run time the server could not find the class file
if i use,
<%@ page import = "FileName.class" %>
then also the same problem persists
& if i use
<jsp:include page = "Relative address"/>
the problem still remains as it is...
please help me out...i am working on developing an EJB application in which client interacts with server's Stateful session bean through a jsp page...it is necessary for me to include the home interface class file in my jsp page.
P.S. do not suggest me to include the class file in a package & then use
<%@ page import = "packageName.ClassFileName" %>

"package University does not exist".How can i overcome this problem. The package University, which you are trying to import, must be in the classpath. If you removed it then you will have to add it back.
i have tried my best..but tell me if there's any possible way of including a class file in the jsp page without involving a package.No, there isn't.
If not,then pls help me to generate the class file of my home interface within a package called test.Read the New To Java Tutorial and understand how packages work.

How to save library symbols' class files in packages that are not the default package?

Hi,
I perform the following in Flash CS5 with Flash Builder 4
1) Create a new library symbol.
2) Do a RightClick->Properties on the new symbol
3) Check the options for "Export for ActionScript" and "Export in frame 1".
4) I write a new name for my class "Class1" and click on the pencil icon "edit class definition" to edit the class.
At this point my FlashBuilder 4 takes over and opens the "New ActionScript" dialog.
4) I then click on Package-Browse to select a package e.g. com.mycompany.myfiles as the new class destination.
The as file is created as com.mycompany.myfiles/Class1.as as everything seems just fine.
5) I close the ActionScript file and back in Flash CS5 I RightClick on the symbol and select "Edit Class".
At this time, FB4 suggests again to create the file, ignoring the fact that I already created it before.
Do you know of a way I can make Flash CS5 remember where I created the file?
Thanks.

Hi,
I didn't remove the project or delete any of the files.
All I did was create the class file under a package that is not the default package. Then when I clicked on the Flash symbol's "Edit Class" It asked me again to create the same class file.
Only if I create the class in the default package, it won't ask me to recreate it again.

How to clear old class files cached in JVM

JVM stores old class files in its cache even after the corresponding files have been deleted from the database. This causes a conflict if a new file is saved with the same name as one that was deleted earlier causing old data to be fetched and not the new one.
am using the following line of code to load the class file :
Class.forName(className, false, this.getClass().getClassLoader())
please help
Thanks - N

Why are you trying to do that?
Dynamic Classloading(reloading) has a meaing only on "application container" like WAS.
Not appropriate for normal applcation.
Focus on enhancing your application logic and algorithm rather than wasting your brain on difficult and meaningless things. Applying some flexible design patterns wouldn't suffice?
Anyway, Sun provides wonderful and simple custom classloader sample.

Anayzing tomcat source(which is downloadable) is another approach.

How can i print my files from mi iphone 5 throught the airport express?

How can i print my files from mi iphone 5 throught the airport express?? i have the last iOS version installed and also the last firmware version of the printer. the printer is already connected to the USB airport express and when i look for printers in airprinter there is no printer found. i have an HP LASERJET P1606dn(i think that is supported by the airprinter).

In order to function with AirPrint, a printer must connect to the network wirelessly.
Even if you have an AirPrint compatible printer, iOS devices will not be able to print to the printer when it is connected via USB.
So, you have two options:
1) Reconfigure the printer to connect to the network using wireless only and the iOS devices should be able to print that way....assuming that you have up to date drivers for the printer installed.
2) Leave the printer connected via USB and then use a third party App like Printopia installed on your Mac as a "workaround" to (hopefully) allow the iOS to device to be able to print. If you want to give this a try, there is a free trial for Printopia, so you will know if it will work before you buy. You must have a Mac running on the network in order for Printopia to function correctly.

i have a seagate 1tb hard drive and a 16gb memory stick, how do i transfer avi files from one to another as the click drag and drop wont work, please help?

Greetings,
What happens when you drag it?
Make sure the drive you are moving the files to has enough available space to receive the file:
Click on the movie file and go to File > Get Info and note the "size"
Check the drive to which you are moving the file to make sure it has enough available space: https://idisk.me.com/madisonfile-Public/web/finder-drive-available-space-and-for mat.html
Also note the format of the drive you are copying too. If it is not Mac OS Extended or FAT (not recommended unless you are taking it to a windows computer) then that may be the issue.
Hope that helps.

Hallo! How can i delete my files wich are saved not on the C: drive?

I'm guessing there must be more to this question than you are stating.
But to answer the question you asked, if you want to delete files that are not on the C drive, select the files and then delete them (press the Delete key, and then Delete from Hard Disk or not, your choice)

How do I transfer photoshop files on my mac air to the larger mac pro?

How do I transfer Photoshop files from my Macbook air to the larger Mac Pro?

There are a number of ways, but the simplest is by USB thumb drive of sufficient capacity. The more elegant if both machines are on the same network is by switching file sharing on on the Mac Pro, and then logging into it from the Air. The Mac Pro drive will appear on the Air's desktop and allow you to simply drag the files over.
For sharing, you will need an account on the Mac Pro, or the ID and password of an account already on the machine.
File sharing basics are outlines in the support document at http://support.apple.com/kb/HT1549?viewlocale=en_US&locale=en_US

Class file is referencing a type outside the classpath???

Hi All,
I'm developing a EJB project in NWDS.
I'm getthing the below syntax error.
This compilation unit indirectly references the missing type com.sap.exception.BaseException (typically some required class file is referencing a type outside the classpath)
Can you please help me to resolve this?
Thanks in advance.
Sundar

Hi Sundar,
You need to add the ejb20.jar file to your Project classpath.
If you are developing the project locally then the jar file can be directly added to the class path using the Project Properties --> Java build PAth --> Libraries tab --> Add External Jar.
If it is a DC development, the ejb20.jar can be found under the SAP-JEE software component of your track.
Hope it helps.
