Spring Integration Test
Nov 18, 2014
In my integration test, I tried to use resttemplate to send a Get request to a dummy server created by MockMvcBuilders. However I got an error:I/O error on GET request for `"http://localhost:8080/test"`:Connection refused:(In the function testAccess(), url is `"http://localhost:8080/test"`). My code is as below:
@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@IntegrationTest("server.port=8080")
public class MyTest {
private MockMvc mockMvc = null;

I am familiar with Servlet/jsp's and developed a web application using them. Now I am looking in Websocket of Java 7. Documentation is not clear how to integrate the two.
1. Let us say in my listener, I have already determined database connections, log file for log4j etc.. Can I use it in Websocket Java classes based on annotation API of web socket. What is not clear to me how I will access Context parameters for webapp saved in Listener.
2. I like jsp so I can dynamically modify the html to be shown. If I am using api, how will I do that, I know I can return data from websocket, but all the java logic which jsp provides, how can that be implemented using web socket api.

I am trying to complete an assignment and I am stuck on a key point. I must print the total inventory value across each of these arrays, as it prints for each "list". To do this, I understand that I need some form of correlation between my variables "total" and "Price" between each array. My quandary lies in the way that I have designed this code to begin with. I am not sure where to add the math section of code that is needed, nor am I fluent enough with Java to know how to call all of the arrays as it prints. Listed below is my code, when you compile it the total inventory value is 0 for each "list".
package inventory;
public class Inventory {
public static void
main (String[] args) {
List[]list = new List[5];

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?

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.

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.

I am going to develop a new web application of medium complexity. Right now i am somewhat comfortable with JSF and hibernate. I have never used JSF and hibernate together before.I just wanted to ask if it is good practice to use JSF (for both view layer and handling business logic) and hibernate(for persistence) without spring as a middle layer. The reason why i am asking this is i don't know anything about spring framework.

There is a weblogic server running at remote place and i need to access the API's in that remote method using JNDI lookup. My application is configured in Spring Tool Suite IDE with java 6 and tomcat 7 and I have used Spring to perform the jndi lookup of weblogic server. In spring i have used simpleremotestatelesssessionproxyfactorybean class to lookup a weblogic server using jndi and get the remote object. But somehow on doing it i'm getting the following error.
org.omg.CORBA.COMM_FAILURE: vmcid: SUN minor code: 203 completed: Maybe
at com.sun.corba.se.impl.logging.ORBUtilSystemException.writeErrorSend(Unknown Source)

at com.sun.corba.se.impl.transport.SocketOrChannelConnectionImpl.sendWithoutLock(Unknown Source)
at com.sun.corba.se.impl.encoding.BufferManagerWriteStream.sendFragment(Unknown Source)
[Code] ....
The exception is been thrown at com.sun.corba.se.impl.encoding.CDROutputObject method when calling writeTo(). Why I'm getting this error and can I do anything to remediate it. Irrespective of java this error occurs, i tried with java 5, 6 and 7 but still getting the same error.

I just wrote a java program with eclipse that has to read many-many inputs from the user. I want to test it, but I really don't want to type it everytime again and again...
Can I just write all inputs in a text file and let eclipse read this file so instead of typing it again and again, Eclipse reads every line whenever it waits for a user input?

I would like to test whether the first word in a line is is a valid var name (e.g sequence of letters, digits and "_", it may not start with a digit, if "_" is the first char it must be followed by a letter). I tried this simple code:
String namePattern = "_[a-zA-Z0-9]+";
String text = "__c";
Pattern pattern = Pattern.compile(namePattern);
Matcher matcher = pattern.matcher(text);
"__c" is an illegal var name.
But it returns the string "_c", where it is supposed to return an empty matcher.
where am I wrong here?

One: is it possible to test code offline with one device, preferably an android tablet?
Two: if, not, is it possible, online with just an android tablet?
Three:if not, is it possible using the internet on my smart phone and with no internet on my tablet - and no, I can't use my smartphone as a hotspot?
I want to test code I wrote on droid edit. An app I purchased for writing code. I'm using Java.

Write a Java program that reads a positive, non-zero integer as input and checks if the integer is deficient, perfect, or abundant.A positive, non-zero integer, N, is said to be perfect if the sum of its positive proper divisors (i.e., the positive integers, other than N itself, that divide N exactly) is equal to the number itself. If this sum is less than N, the number is said to be deficient. If the sum is greater than N, the number is said to be abundant.
For example, the number 6 is perfect, since 6 = 1 + 2 + 3, the number 8 is deficient, since 8 > 1 + 2 + 4, while the number 12 is abundant, since 12 < 1 + 2 + 3 + 4 + 6.
Sample Output:
Input N: 5
5 is deficient.
Input N: 6
6 is perfect.
Input N: 18
18 is abundant.

Any compact if statement or any type of test for checking if atleast ONE out of 4 integers is null. So 1 of all, 2 of all, 3 of all, or all of them being null will give a specific result ELSE do something else.
