JAMON Spring Unable To Monitor Exceptions
Jul 12, 2014
I am currently working on integrating JAMON version 2.76 in our existing application
following are details of environment
JDK 1.5
Server weblogic 9.2
OS windows
Spring version 2.5
first we have added following entry for jamon monitor
<bean id="jamonPerformanceMonitor" class="org.springframework.aop.interceptor.JamonPerformanceMonitorInterceptor">
<property name="useDynamicLogger" value="false"/>
<property name="trackAllInvocations" value="true"/>
</bean>
then added this interceptor as preinterceptor in existing
<bean id="applicationBO" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
<property name="transactionManager">
<ref bean="transactionManager"/>
</property>
[Code].....
currently we can able to monitor all calls given to this class but whenever any exception thrown in this class hierarchy we are not able to track it on exceptions.jsp of JAMON

I thought that simply constructing a progressmonitor would show the dialog, and wrote the following code.
[Code] ....
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.beans.*;
import java.util.Random;
[Code] ....
But apparently i was wrong and all i get is an empty JFrame and no Dialog. I even added my own subclass of SwingWorker in case a SwingWorker had to be created in order for a progress monitor to exist. How can I make it show?

I'm building an application in Netbeans and so far I'm making good progress with it. I have created an animated splash screen in myspacegen.com and then downloaded it as a GUI file. I've then imported it into my application in Netbeans but I was restricted in myspacegens.com to the size of the image I could create. I want to know if it is possible to add code to the splash screen project within Netbeans so that it automatically adjusts to fill the screen. I have used the java commands get width and get height elsewhere in my application so that the window I create in a project automatically adjusts to fill the operator's screen but that has a 'window' to adjust and I do not want my splash screen to have a visible window.

I have imported several maven projects but I am trying to import a spring project via eclipse and it is not displaying. I did the following file->import->Existing maven projects->browse (found my project)->finish..... The project does not display and I cannot find it. I tired to do it again and the project cannot import because I cannot select it meaning it is already installed.

I'm running spring MVC on a tomcat server and am fiddling around with beans and annotations.
First, I have a class Library, with a registerBook(<T> Book) method. This one is annotated with @BookRegistry
Next, I have an Interface Book, which basically is a bean with some custom methods.
I will create different types of books that implement my Book interface and annotate them with @LibraryBook
Now, I want to have spring to check for all beans with @LibraryBook at server startup and run registerBook for each and every one.
How do I accomplish this?

My requirement is to display a table containing multiple rows and multiple columns. and row headers must be link type and that table should be retrieved dynamically from db where the values entered by the admin. this is the user view. and am new to spring. unable to implement this. my demo is on monday and i need to show the demo to survive in this job. I had given the link. but am unable to implement by seeing that also because it has no complete code which is my actual requirement. Code should be written in controllers, pojo, dao's, jsp's etc... URL....
In my code am unable to get in one table. So I went with alternative that to come each row and 3 columns in one table... 4 rows 4 different tables I did... but it was not my requirement. I used embedded to get that...in my pojo I wrote
@Embedded private BaseCost baseCost;
@Embedded private OtherCharges otherCharges;
@Embedded private PreferentialLocationalCharges preferentialLocationalCharges;
@Embedded private CarParking carParking;
and each embedded one i have created 4 pojo's where i wrote column headers. get it all in one table view with 4 row headers and 3 column headers but this is not my requirement...

I create a spring layout like so
Container contentPane = this.getContentPane();
JLabel characterLabel = new JLabel("Character: ");
JComboBox<String> characterComboBox = new JComboBox<String>();
characterLabel.setMinimumSize(characterComboBox.getMinimumSize());
[Code] ....
and I have attached an image of the results.
Why are the drop down boxes not stretched to the right all the way and why are they so tall?

I am just learning how to throw exceptions, and I'm stuck on the last part,
Here is where I created the exception that receives a string consisting of ID and wage.
public class EmployeeException extends Exception
{
public EmployeeException(String Employee)
{
super(Employee);
}
}
Here is where I created the Employee class with the two fields. I also believe I am throwing the exception if the hourly wage is < $6 or > $50.
public class Employee
{
int idNum;
double hourlyWage;
public void Employee(int empID, double empWage) throws EmployeeException
{
idNum = empID;
hourlyWage = empWage;
[Code]...
Now, I need to write an application with three employees and display a message when an employee is successfully created or not. This is what I have so far... I'm trying to get it to work with one employee, and then I can easily go back and add two more.
import javax.swing.*;
public class ThrowEmployee
{
public static void main (String[] args)
{
try
{
Employee one = new Employee(542, 15.20);
}
[Code
The current compile error that I'm receiving is: ThrowEmployee.java:12: error: constructor Employee in class Employee cannot be applied to given types;
Employee one = new Employee(542, 15.20);
^
required: no arguments
found: int,double
reason: actual and formal argument lists differ in length
1 error
I have public void Employee(int empID, double empWage) in my Employee class, so why is it saying that no arguments are required? Not sure if I'm missing a step with throwing exceptions, because this error has always been a simple fix when I've come across it in the past?!?

In my EJB modules, to prevent that any JPA exception is ever thrown, I check the condition that would cause the exception beforehand. For example, the exception javax.persistence.EntityExistsException is never thrown because, before persisting the entity, I check if such primary key already exists in the DB. Is it the right way to do this?
Another approach is too allow the JPA exceptions to be thrown and catch them in a try-catch block, and then throw my custom exception from the "catch" block. However it requires to call EntityManager.flush () at the end of the "try" block. Otherwise the exception throw could be deferred and never be caught by my block.

URL....In the mentioned project in this blog I used Spring Web Flow to satisfy some requirements but now that development of the Spring Web Flow stopped I like to check what Faces Flows can present to satisfy the same requirements.From a quick look similarities between Spring Web Flow and Faces Flows are obvious but there is one specific point I like to ask.In SWF it is possible to define flowing element at the beginning of an flow.
<on-start>
<evaluate expression="CustomerSearchSM.resetStateMachine()"/>
</on-start>
which will trigger an event when you will start executing a flow, I look to the Faces Flows flow descriptors but I can see an element that fullify similar requirement.similar functionality built into the Faces Flow or not?And is there a way to configure Faces Flows that it reacts to events from the users like the following.
<transition on="onStartCustomerSearch" history="invalidate">
<evaluate expression="customerSearchInputBB.searchCustomer()"/>
</transition>
<transition on="onCustomerAuthenticated" history="invalidate">
<evaluate expression="customerSearchAuthenticationBB.customerGivesAuthentication()"></evaluate>
</transition>

I am trying to find a way to make a URL that is used during a background AJAX call to log a user out more flexible. Currently, I have it as a static value, as below:
var logoutURLTest = "https://test.myorg.com/cas/logout";
...AJAX stuff that uses the logoutURLTtest variable...
However, if that URL was to change for any reason, I would have to modify one or more JSPs if they were affected, instead of just changing it at a single point in the Spring environment context. It would be more desirable to expose the value using a property placeholder; however, the Spring documentation isn't exactly clear on whether this is possible.

in my ui i will i will select enabled or disabled then it will go in controller , i already debug it and it goes on the right controller based on what i select on ui my problem is when i select disabled it dont display the message but when i select enabled it displays the message, then i check the databases status is change based on what i select but when i change into disabled doesnt display any message.if select enabled will go in controller then change status into true then update the status then will see the message in ui
@RequestMapping(value = "/viewEnabled/{id}", method = RequestMethod.POST)
public ModelAndView viewEnabled(
@PathVariable("id") Integer id) {
ModelAndView mvc = new ModelAndView();
Supplier supplier = supplierService.retrieveSupplier(id);
supplier.setEnabled(true);
supplierService.updateSupplierEnabled(supplier);
mvc.addObject("showEnabled", true);
mvc.addObject("supplier", supplier);
[code]....
The main functionality of enabled /disabled is both working it just dont display the message if i change it into disabled,.

When I hit the url at the first time my call goes to the spring controller and sets the userDetails objects in the modelAndView.addObject("userDetails", userDetails.getUserDetails()) and returns the userDetails.html page. if I click any link in the same page i want to pass same (userDetails) object thru javascript or jquery and calls the another(controller) method and returns the same (userDetails.html) page.
It means how can I pass the java object thru javascript or jquery and calls the controller. If I get the same object in my controller i can avoid calling the db again.

There are times that my methods need to report the caller about many kinds of errors, represented as checked exceptions. This makes my methods look like very convoluted. It happens mostly when I work with stateless EJBs and databases. Sometimes I end throwing even 8 different exceptions! Are they too many?
Many of them inherit from common exceptions, so I've been tempted to throw the parent classes. But I've quickly discarded that option because I've read that it's a bad practice, since a method may throw only a subset of the children of that parent class, not all.
Finally, I've studied these possibilities:
1. Throwing the parent class (mentioned above).
2. Throwing a common exception with an error ID or code as message.
3. Throwing a common exception with an enum as member, as if it were an ID or code (safer than the #2).
All them show the same defect that the #1. However it's more a conceptual problem than a technical one, because my callers always use the same mechanism to treat every "specialization" of the same exception, without worrying about if the method really can return it or not.

I want to test that a function has no any exceptions.In C++ and Google Test Framework (GTest) it will look like this:
ASSERT_NO_THROW({
actual = divide(a, b);
});
How will it look in Java?

I'm writing a program that accepts three doubles from the user, and performs calculations on them. I want to be able to handle input mismatch exceptions on each individually (i.e., if the user enters a double for the first, then a letter for the second, I'd like to be able to keep the value entered for the first, and only require that the user try again with the second, then the third, etc.)... I tried putting each input instance into its own try/catch blocks, but it always goes back to #1 when an invalid input is entered. Right now, I have all three in one try/catch:
Java Code:
package com.itse2317;
import java.util.Scanner;
import java.util.InputMismatchException;
class Triangle
{
public static double side1 = 0.0, side2 = 0.0, side3 = 0.0;
[code]...

I'm wondering about the use of exceptions to handle errors that might occur during file I/O when the I/O is done by a method implementing an interface's method. The idea is for the interface to provide a uniform way for application code to read (and write, though I'm not addressing that in this post) a document from a file, given a File object that specifies the on-disk location of the document. The "document" can be an instance of any class the application programmer wants it to be, provided that it can be created from a file stored on disk. Here's the interface definition:
public interface DocumentRamrod<T>
{
public T openDocumentFile(File file) throws FileNotFoundException;
}
A simple implementation, when T is a class that just holds a String, might look like this (Please overlook the fact that there is no call to the BufferedReader's close method, as it's not needed for this example.):
public class MyRamrod implements DocumentRamrod<OneLineOfText>
{
public OneLineOfText openDocumentFile(File file) throws FileNotFoundException
{
return new OneLineOfText(new BufferedReader(new FileReader(file)).readLine());
}
}
But, that one line where the file is read (Line 5) might generate an IOException.To cope with it, I could add a try-catch to the implementation like this:
public class MyRamrod implements DocumentRamrod<OneLineOfText>
{
public OneLineOfText openDocumentFile(File file) throws FileNotFoundException
{
try
{
return new OneLineOfText(new BufferedReader(new FileReader(file)).readLine());
} catch (IOException ex)
{
Logger.getLogger(MyRamrod.class.getName()).log(Level.SEVERE, null, ex);
}
}
}
Or, I could add that to the list of exceptions defined for the method in the interface, like this:
public interface DocumentRamrod<T>
{
public T openDocumentFile(File file) throws FileNotFoundException, IOException
}
But that's where I'm getting nervous, as it makes me realize that, with an infinite number of possible implementations of openDocumentFile, I can't predict what all the exceptions thrown might be.should I have openDocumentFile simply throw Exception, and let the application programmer sort out which one(s) might actually be thrown, should I keep listing them as it become clear which ones are likely to be thrown, or should I not have openDocumentFile throw any exceptions and let the application programmer deal with it in the implementation of openDocumentFile (with try-catch blocks, etc.)? In Good Old C, I'd have passed back a null to indicate some general failure, with the various callers up the call-stack having to either deal with it or pass that back themselves (until some routine up the stack finally did deal with it), but that seems like an approach the whole exception mechanism was designed to avoid.
I'm thinking the right choice is to have openDocumentFile throw Exception, and let the application programmers decide which subclasses of Exception they really want to deal with. But I have learned to be humble about the things I think, where Java is concerned,

I am having some difficulties grasping the concept of throwing your own exceptions. How do I get this to repeatedly ask the user to enter a valid value for hours. Also i am having difficulties in the method with using the throw new InvalidHrExcep("That value is invalid"); i cannot get this to work.
public class exceptionProgram {
static Scanner console = new Scanner(System.in);
public static void main(String[] args) throws InvalidHrExcep
{
int day=0;
int month = 0;
int year=0;
int hours=0;
int minutes=0;
int seconds=0;
[code]...

consider:
class A {
final Object b;
public A(C c) {
try {
b = c.someMethodThatMayThrowSomeException();
} catch (SomeException e) {
b = null; // This line results in compiler error: "variable b might already have been assigned"
}
} // take away b=null line and you get "variable b might not have been initialized" on this line
}
Why? How could 'b' be assigned if the exception was thrown?
Btw, the workaround is to wrap the method call:
private final Object initB() {
try {
return c.someMethodThatMayThrowSomeException();
} catch (SomeException e) {
return null;
}
}
and use b = initB(); in the constructor. But that seems like it should be unnecessary.
