Integrating performance evaluation with existing java code.

I have a few methods and I want to integrate a custom timer class which will measure the time taken for the method to execute. basically the timer class just starts the time at the start of the method and once the method completes it subtract the final time from the start time to give me total time spent in this method. I was wondering if there's a way by which i can integrate my timer without actually changing my methods.I have to start the timer when the method is going to execute and end the timer once it has finished executing. Any design pattern you think could help me?

Welcome to the forum. I think that George123 has your problem and its solution well in hand. Follow his good advice and you will have solved this problem. One other thing though just for future reference. If you post your code, here, you are going to want someone to be able to read it easily. Please use code tags when posting next time and your code will be much easier on the eye. You can find out about them here:

Performance problems with new Java Tiger style recommendations

Performance problems with jdk 1.5 on Linux plattform
(not tested on Windows, might be the same)
using the new style recommendations.
I need fast Vector loops for high speed mathematical calculations, some
hints about the fastest way to program that loop would be also great!
After refactoring using the new features from java 1.5 (as recommended from
SUN) I lost performance significantly:
using a vector:
public Vector<unit> units;
The new code (recommended from SUN for Java Tiger for redesign):
for (unit u: units) u.accumulate();
runs more than 30% slower than the old code:
for (int i = 0; i < units.size(); i++) units.elementAt(i).accumulate();
I expected the opposite.
Is there any information available that helps?
The following additional information I got from Mr. Shankar Unni:
I got some fairly anomalous results comparing ArrayList and Vector: for the
1.5-style loops, ArrayList was faster then Vector, but for a loop with get()
calls, Vector was faster. Vector was even faster than that using
elementAt(), which was a surprise:
For a million summing iterations over a 100-element array:
vector elementAt loop took 3446 ms.
vector get loop took 3796 ms.
vector iterator loop took 5469 ms.
arraylist get loop took 4136 ms.
arraylist iterator loop took 4668 ms.

Use Sun Java Studio 2 with Existing Java Application

I have started using Sun Java Studio 2 and having fun and little difficulty creating a new Java web application from scatch. My question is where do I find information on Java Studio configuration to allow Java Studio to load up and modify Java server pages/forms in an existing Java application that I did not write?
The Java application has been created with Javabeans and using BEA Weblogic version 7, with a SQL-Server 2000 database backend.
Below is a bit of code out of one of the main Java forms.
<%@ page buffer="256kb" autoFlush="false" errorPage="../../common/system/error.jsp"
import="psdi.jsp.beans.*, psdi.jsp.common.*, psdi.jsp.app.wotrack.*, psdi.jsp.util.* , psdi.mbo.* , psdi.util.* "%>
I have looked around and have not found what I need to setup in Java Studio to allow me to load up a form and view it in the Visual designer, I keep getting errors on the psdi. references and cannot load up any pages.
I see on the server install ia folder under the main root <DIR> called <apps>, and inside the <apps> folder is a folder called <jsp> and in the <jsp> folder are sub folders for each main module within the application with all the related .jsp files. I have been manually editing the .jsp files using Windows Notpad and saving the changes. Then I rebuild the .ear file and my changes work fine. Since I have a lot of changes to make there has to be a better way than using Notpad.
My hope is somewhere is a point-by-point document on what to so I can use Sun Java Studio 2 to make my changes in a visual IDE.
Any assistance would really be appreciated.

Hi Giri,
Yep, this I know,b ut when I do I get errors messages and am looking for some form of point-bypoint instuction that better explains how to setup up custom libraries in Sun Java Studio, custom tags, etc.

Help me with my java code

i have an assignment from the book java programming d.s malik.
problem:
for research purposes and to assist students, the admissions office of your local university wants to determine the performance of the female and male students in certain courses. You receive a file that contains female and male students' GPAs for certain courses. Due to confidentiality, the letter code f is used for female and m is used for male. every file entry consists of a letter code followed by a GPA. each line has one entry. the number of entries in the file is unknown. write a program that computes and outputs the average gpa for both female and male students. format your result to two decimal places.
solution:
this is what i have come up with:

JVM 1.4 seg faults with pure java code?

Has anybody else seen JVM 1.4 seg fault when running pure java code? This seems like it shouldn't be possible, but I get the following at indeterminate times. Unfortunately, it is difficult to isolate since decreasing the size of the program avoids the problem. When the seg fault happens, the size in memory is ~1GB and there is plenty of real and virtual memory to spare.

Hi sevenM,
Did you figure out a workaround for this problem?. Did you get it solved with the SUN people?. Is it a known bug?.
I've got exactly the same problem on the same function and VM library.
Any info on this is very much welcome.
Thx
Krithiga
I get the same error sometimes with tomcat-4.0.4 on a
Slackware 8.0.0 and JDK 1.4.0. I don't user any JSPs,
only servlets and the business calls a remote SLSB on
a remote JBOSS server and afterwards select some data
form a remote DB2 7.1 over JDBC.
Here is the log:

Problems with backing Java Code

Earlier I manually deleted the processChange event handler method for a textfield from the backing java code. As I had no plans to use that event handler. Now my page abends with a message stating that the process chnage method is not available. I tried to add via the event handler for the textbox using the GUI but it does not add the process change event handler method. Using an another process change method as a model I manually entered the code to handle process change for the text bos. Now I am getting an internal server exception - Null in one of the parameters. PLEASE HELP. What are my options - Delete and re-create the entire page

Hi,
Yes I am using the recommeded code: The Text field generating the null exception is addDataSourceTF. Whenever we click on the addDataSourceBTN we get an Internal exception.
Thanks very much for looking into this problem. Any advice will be greatly appreciated.

Re-installation with existing product code/disk but no disk drive.

I have a new laptop and need to re-register my Photoshop C6 student and teachers edition, can I do this with my existing product code?
Also if it is possible, how do I then re-install Photoshop with no disk drive? (I originally just popped the disk in and entered my product code.)
(Additional information: Both my laptop and Photoshop are for Windows.)

Hello,
if you are able to do that, you should deactivate (Help -> Deactivate) the Adobe software before you lose the machine to it being reset. You will still use the same serial number to activate the soiftware when you get the application(s) reinstalled.
If you need any help with activation you can contact Adobe Support directly by chat or phone.
Here is a link to a page with options to help make contact: (Contact Support – Download and Installation)

Creation of 2 new company codes in continuation with existing compny code.

Hi
Our company has got 2 locations but we are using only one company code for both the locations from the last 4 years.
Now due to expansion of business we have extended our business to one more location. So.now are planning to use 3 company codes.
Now I want to know the following things:-
1. What are the things that are to be done before creating these two additional company codes?
2. What will be the impact of these new company codes on the existing company codes?
3. How the present reports can be used for the new company codes?
4. How the GL balances will be uploaded for the new compny codes?
5. How the master data will be created for the new company codes?
6. What will be the impact of the new company codes on other modules like MM, SD and HR which are already in use?
Please guide me on the above issue co months of experience.
considering the fact that I am a fresher in SAP FI and I have
only 8 months of experience.
Regards
Vikram sairam

Hi Vikcy,
Company Code is legal Entity and core component in FI.
Now u r planning create new company codes, just check below:
01. Chart of Accounts:
- You may use existing chart of account for new com. code
02. Controlling Area:
- Check the feasibility of cross company code controlling or not. If you maintain one:one relation in existing controlling area, u need to create new one.
03. SD: Core component is Sale Organization. U need to assign them to ur Company Codes. So check accordingly.
03. MM/ PP: Plants and Purchasing Organization need to assign to Company Codes.
Hope it will give you idea on a whole to plan, how u need plan to go ahead.
Regards,
Venkat

Implementing DOM Interface with existing Java classes

I had planned on using some tree-like Java classes as a Document Object Model, which would give me access to all sorts of XML and DOM tools like parsers and XSLT transformers. Initially, I thought all that would be neccessary is to implement all the DOM Interfaces in org.w3c.dom and then I would have a set of classes that conformed to DOM Level 1. It was my understanding that interfaces such as DOMImplementation and Document would interface with various XML tools, allowing creation of a class that implements Document and then Document would have its various factory methods that know how to create the various DOM nodes such as Element, Attr, Text, NamedNodeMap, NodeList, etc.
The problem I'm seeing now is that the JAXP specification (which is what the latest Xerces and Xalan tools conform to) has something called a DocumentBuilder and DocumentBuilderFactory that appear to be necessary to tell the framework what type of class to instantiate that implements the Document DOM interface. Those appear to have a lot of methods that deal with parsing of XML documents and I didn't really want to write or even subclass any existing Parsers in order to get the functionality of traversing and transforming a set of classes that implement the DOM interface.
Am I missing something here? Is it possible to plug in any (set of classes for) DOMImplementation and get them to work with the various DOM and XML tools out there?
Is there an easier way to allow parts of an application access to internal data structures but have the more generic tools or APIs, such as XSL transformers, access that same set of classes as a DOM with the generic DOM interface methods?
Can someone provide me with some guidance here? I'm in the process of finalizing some design on a system and need to know if this is possible or if I need to alter my design.
Thanks.

If I understand you correctly, I think I am working on a similar issue. I am unhappy with the methods given by the DOM for retrieving data from the XML file and for building a file. Our software has a bunch of code that uses these classes and it is extremely ugly. My solution was to create a facade on top of the DOM model. Essentially I have some simple classes that store all the pertinent info (for me) about the XML structure. Essentially that is the element or attribute name, its values and in the case of the element, it's children. This makes it easier for me to build and retreive the data. What I then built was a loader class and a builder class. The loader takes an XML file and parses it in using the DOM classes and builds a structure using my classes and returns the root element. The builder takes a root element and creates a DOM object out of it. This frees me of having to code around the DOM classes all over the place and makes it simple to upgrade our XML code if the DOM changes or a better DOM is released. I am using factories to facilitate this and allow me to have loaders for specific types of XML documents so that I can have a class for each which further simplifies the XML related tasks of other developers on my team.

Performance issue with pl/sql code

Hi Oracle Gurus,
I am in need of your recommendations for a performance issue that I am facing in production envrionment. There is a pl/sql procedure which executes with different elapsed time at different executions. Elapsed Times are 30minutes , 40 minutes, 65 minutes , 3 minutes ,3 seconds.
Expected elapsed time is maximum of 3 minutes. ( But some times it took 3 seconds too...! )
Output on all different executions are same that is deletion and insertion of 12K records into a table.
Here is the auto trace details of two different scenarios.

          -------------------------------------------------------------For security reasons, I cannot share the actual code. Its a report generating code that deletes and load the data into table using insert into select statement.
Delete from table ;
cursor X to get the master data ( 98 records )
For each X loop
insert into tableA select * from tables where a= X.a and b= X.b and c=X.c ..... ;
-- 12 K records inserted on average
insert into tableB select * from tables where a= X.a and b= X.b and c=X.c ..... ;
-- 12 K records inserted on average
end loop ;1. The select query is complex with bind variables ( explain plan varies for each values )
2. I have checked the tablespace of the tables involved, it is 82% used. DBA confirmed that it is not the reason.
3. Disk reads are high during long execution.
4. At long running times, I can see a db sequential read wait event on a index object. This index is on the table where data is inserted.
All I need to find is why this code is taking 3 seconds and 60 minutes on the same day and on the consecutive executions ?
Is there any other approach to find the root cause of this behaviour and to fix it ? Kindly adivse.
Thanks in advance your help.
Regards,
Hari

This would improve readability greatly and will help us to help you
example
{<b></b>code}
select * from dual;{<b></b>code}
Based upon your description I can imagine two things.
a) The execution plan for the select query does change frequently.
A typical reason can be not up to date statistics.
b) Some locking / wait conflict. For example upon a UK index.
Are there any other operations going on while it is slow? If anybody inserts a value, then your session will wait, if the same (PK/UK) value also is to be inserted.
Those wait events can be recognized using standard tools like oracle sql developer or enterprise manager while the query is slow.
Also go through the links that are in the FAQ. They tell you how to get better information for makeing a tuning request.

Needed help with updating java code

Hello all,
Let me begin by let you know I am not a programmer and I have tried to solve this by reading on the net. I am a network admin so I tech knowledge but no programming.
I have a webcam sending a Jpg to an FTP site and there I have used an applet called view.class to refresh once a second.
site:http://70.154.170.253/webcamold.html
My problems is now that it refreshes the same image over and over. It refreshes the cached image not the new image.
From reading I suspect that it has to do with the newer version of java (it used to work fine).
I have tried using JavaCam but same issue it just refreshes cached image. Also image flickers, the applet I am trying to fix was really smooth.
I have also tried to compile code that I found on this forum but I got error dealing with deprecated code.
Any help would be greatly appreciated!!!
Code:
import java.applet.Applet;
import java.awt.*;
import java.io.PrintStream;
public class View extends Applet
implements Runnable
public void init()
setBackground(Color.white);
String s = getParameter("refresh");
if(s == null)
update = 30;
else
try
update = Integer.parseInt(s);
catch(Exception _ex)
update = 30;
filename = getParameter("picture");
if(filename == null)
System.out.println("No filename given as parameter.");
md = new MediaTracker(this);
off = createImage(size().width, size().height);
refreshImage();
public void paint(Graphics g)
g.drawImage(off, 0, 0, this);
public void update(Graphics g)
paint(g);
public void refreshImage()
img = getImage(getDocumentBase(), filename);
md.addImage(img, 0);
try
md.waitForID(0);
catch(Exception exception)
exception.printStackTrace();
Graphics g = off.getGraphics();
g.drawImage(img, 0, 0, this);
img.flush();
public void run()
while(th != null)
try
refreshImage();
repaint();
Thread.sleep(update * 1000);
catch(Exception exception)
System.out.println("Error when thread was supposed to sleep: " + exception.getMessage());
public void start()
if(th == null)
th = new Thread(this);
try
th.start();
return;
catch(Exception exception)

How can i retrieve a computer name with a java code

hello friends,
please, can i get help on how i can rtrieve the name of a computer(any at all) using java - a code will be appreciated.
i also wish to ask if you know how i can use the JFileChooser class, such that when i click on a file to select it and then click on the open button, the file will open / show in a TextArea which i have already created.
Moreso, how can i use the JFileChooser to save something i've written in a TextArea, as file to a system.
thanks in advance for your useful advice. quite grateful.

'result' is a String I think.
As for your JFileChooser question...
Create your take the file returned from JFileChooser, open it in a BufferedReader (I'm assuming it's text as you want to display it in a JTextArea) then read the lines out.
JFileChooser fc = new JFileChooser();
fc.showOpenDialog(null);
File file = fc.getSelectedFile();
if (file != null) {
try {
BufferedReader in = new BufferedReader(new FileReader(file));
String inputLine;
String total = "";
while ((inputLine = in.readLine()) != null)
total+=inputLine;
in.close();
textarea.setText(total); // textarea = your JTextArea
} catch (Exception e) {
System.err.println("Error: "+e);
}

Error in deploying BPEL Process with Embedded Java code

Hi all,
I am trying to do a simple sample BPEL Process which invokes a Java class.i have placed the jar file in the classpath and the Process compiles and builds in the BPELDesigner,but when deployed it shows the below error in the BPEL console.The beauty here is it show a success message in the BPEL Designer after deployment.
