How can i built a java application using java debug class on Log4J

Hi,
As java API support the MethodEntryEvent, using which I can get the automatic logging statements when the method is entered or exited as HelloExample.main(with argument type).
Where HelloExample is the class name.
Main is the method entered with its argument types.
In some cases I have the o/p as
-- VM Started --
====== main ======
main -- HelloExample
callerMethod -- HelloExample
====== main end ======
-- The application exited --
By using Log4J is there any possibility of getting these sort of o/p along with the loggers supported by Log4J. i mean to say can i built an java application which supports the MethodEntryEvent and MethodExitEvent from java API and also uses the Log4J debugging. I took an e.g. trace example, which (in J2SE 1.4.x or 5.x) will be found in $JAVA_HOME/demo/jpda/examples.jar and unpacking it by
jar -xvf $JAVA_HOME/demo/jpda/examples.jar i found the com/sun/tools/example/trace/Trace.java and passed the class constructed with logger taken from Log4J. In this case the logging message is displayed on the console. As per the requirement i need to transfer the whole o/p to an output file along with Log4J logger statements. in this case i should not give any command in the cosule except compiling and executing the programme. the programm also should able to run without the main() as i need to integrate Log4J with an application and the code must me application server independent. i need the output as i got using MethodEnteryEvent (shown as above) in case of java application built using Log4J.
Can any one help me in this regard. can any one give me some suggestion or any programme of this sort. All suggestions are welcomed.
Thanks & Regards,

hi,
can someone help me how to implement logging for method entry parameters and
method exit return value.
can someone help me how to use log4j and integrate it to the method entry
logging and method exit logging.
Here what i need is without writing the log statements for the method entry and
method exit i need to log it to the file
along with other log4j debug statements i provide in the file.I should be able
to configure whether to enable/disable the logging
for method entry and method exit. In method entry i should be able to log the
parameters the method take and in method exit
i should be able to log te return value to the log file, before the method is
returned to the callee.
i hope i am clear
Thanks in advance.

Deploying no java applications using Java Web Start

Hi,
I am new to java web start. Is it possible to distribute non java applications using java web start. I have an APP which can run on a desktop in standalone mode. The app has jusy HTML and Java script files. Is it possible to package this app and deploying using java web start? I am assuming If it is possible, I can make updates to the packaged app in the web servers and the updates will be downloaded next time the app is used provided configurations are correct?
thx

The app has jusy HTML and Java script files. Is it possible
to package this app and deploying using java web start? Not really. Resources for JWS need to be zipped,
while this HTML/JS app. will (I guess) not work from
inside the depths of a Jar (or Zip) archive.
Note that you can organise for those files to be
downloaded and expanded onto a known place
on the user's disk, by using an 'installer' element,
but..
...I am assuming If it is possible, I can make updates to the
packaged app in the web servers and the updates ..installers are only called once, and do not 'update'.

How can an email account be created using Java mail on the FLY.

Scenario is such that i am using mail server from MDaemon.com and JavaMail api,and making Email website like yahoo...some what ! but how can a user create his account by just filling the form and when he enters his account be created in Mail server..

Last time I checked MDaemon has its own API for account management. I have never tried to do anything with it but their sales literature says it exists.
Account management will be specific to the platform and mail server software. This is beyond the scope of JavaMail which is for message transport (and management to an extent on IMAP servers), not account management on the server.
The other alternative is to write your own application that modifies the structures used by mdaemon but since it already has an API why bother.

How can i design a EJB application using session Beans?

Hello,
I am designing a Find application using EJB. Here a user is prompted a search page, where he can enter the search criteria's. Then on click of submit, the query is formed at the server side depending on what criteria's were selected. Then a jdbc query is performed and the results are returned back to the user. Here no session is maintained for the users. Can anyone suggest me how to design this application using EJB. Should i use entity beans for this or session beans will suffice? Should the jdbc query be performed in the bean itself or should it be outside in a helper class? Please kindlu suggest me the design for this application...
Regards,
Subbu

Hi,
First of all, I'm unable to figure out why you need to use EJB for this scenario. You can write a helper class to frame and execute the query.
If you really want to use EJB, then I suggest you use a stateless Session Bean with transaction attribute as TX_NOT_SUPPORTED. From the session bean, you can call the helper class. But, by avoiding the session bean, you can eliminate remote calls, thus improving your performance. Also, check if the database & the db driver you are using supports sql caching.

Raj.

How can I develop a web application using EJB design pattern?

I have searched over the web and found quite a lot of tutorials on how to use the EJB design pattern.
I know that there will be a home interface, EJB object interface and a SessionBean.
But the tutorials often only cover a single class, this made me unable to get a complete picture of how EJB design pattern can be implemented into a whole system.
I am now required to devleop an online shopping web application using EJB and JSP page.
I think I will need to create a lot of classes: Member, ShoppingCart, Product...etc.
What I want to ask is that, do I need to create a home interface, EJB object interface and a SessionBean for each of these classes?
I really need some ideas on how to develop this system using EJB + JSP pages.
Many thanks to you all.

For every EJB that you want to create, you will need to code a home and remote interface and a bean class.
You could start getting your ideas here

How can I connect to a database using Java Web Start?

When I run the application without Java Web Start, the program can get the driver and connect to the database. However, when I try to use this same application with Java Web Start, the program can not load the driver. Why is this happening? I am using a mySql database driver.

I assume you are trying to connect using JDBC, are did you include the jdbc jar in your resources ?

How can I open/save .xlsx file using java

Hi
I have a jsp whose contenttype of response is application/vnd.ms-excel.
When I am saving the file as .xlsx and opening from disk it displays error message.
How can I save and/or open the file as .xlsx?
Any advice will be appreciated.
Thanks

Checkout the Apache POI XSSF API or the OpenXML4J API's to create xlsx files and use a servlet to write it to the outputstream.

Disk Space "leaking" in Java Application Using java.io.RandomAccessFile

I have noted this behaviour in both java version 1.2.1 and 1.3.1 on Solaris 5.8.
I have a java application that is essentially "tailing" a very large log file.
The program opens a RandomAccessFile in read-only mode and calls readLine on the file as long as the file is getting written to.
If the file stops getting updated the program assumes the logfile has been moved/rotated/wrapped (by an external process) and the program the calls close and then reopens the file to allow the program to start reading from the new file and to allow the O/S to free up the system resources.
It appears that the program is not actually closing the filehandle or releasing the disk space and eventually the disk fills up.
When this happens the program is stopped and restarted and the disk space is freed up.
We have run the pfiles command against the running process and have confirmed that the old filehandles are still open.
I have attached what I think to be the relevant code lines below:
RandomAccessFile filehandle = null;
boolean reopen = true;
boolean connected = true;
while(connected)
if (reopen)
while(! new File(filename).exists())
doSleep (filewaittime);
filehandle = new RandomAccessFile(filename, "r");
while (file_being_updated)
// read from the file etc.
filehandle.close();
filehandle = null;
reopen = true;
The reopen flag is set to false in code not shown here.
I have verified that the block of code that calls close() on the filehandle and sets it to null is being executed when the logfile is moved externally.

Hmmmm. Sounds like a hint to me :)
I am still experimenting but I will certainly try moving to the latest JDK and report a bug if I don't figure this out on my own.
Thanks.

You could use java.lang.Runtime.exec(). Another way could be loading the main class of the jar file and invoking its main method dynamically.
