I am trying to understand the effect of calling real business logic from the test class. If I have a test class that call the service method which make update to DB. Is DB really changes through test class?
e.g.
Java Code: @Test
public void testUpdate() {
MyDto myDto = new MyDto(paramters to create new myDto object); //creating new dto object
myService.updateMyData(myDto); //passing new dto object for update (DB record really changed??)
MyDto testDto = myRepo.find(myDto.getKey()); //get record for the corresponding key
assert testDto.getSomeProp() == myDto.getSomeProp(); //what testDto.getSomeProp() return? new value send on myDto or old value from DB?
} mh_sh_highlight_all('java');
I am new to web services and need to call a web service that has already been written. Below is the wsdl for the web service.I need to call the web service from my java program. provide the code to call the webservice?
I am basically a Dot net developer. now im working on one Android project. my requirement is,
1. I have to call a web service, that will return XML data as String. 2. I have to read that XML string data. 3. Store those xml data into class collection(Collection is C# word, i dont know how here calling)
#1 i have done, #2 & #3 is pending. I knew reading xml is using SAX parser but, i dont know how to read from String using SAX.? Then how to store those XML data into a collection object.?
i tried with this link [URL] .... but, its confusing bcos, I am writing code Activity class but, there explaing with some Void Main class.
Regarding the lifecycle of servlet , in headfirst servlet i can find :
You normally will NOT override the service() method, so the one from HttpServlet will run. The service() method figures out which HTTP method (GET, POST, etc.) is in the request, and invokes the matching doGet() or doPost() method. The doGet() and doPost() inside HttpServlet don’t do anything, so you have to override one or both. This thread dies (or is put back in a Container-managed pool) when service() completes.
How can I call the doGet method of the subclass from the superclass. i am not getting this .
For reference I am programming Java in BlueJ. I am fairly new to the language and I am having trouble with sorting.
I am trying to call / test all of the 5 sorting methods (at the same time) in the main class. To be specific, the sorted list has to technically outputted 5 times.
I figured out how to call / test Quicksort:
Sorting.quickSort(friends, 0, friends.length-1);
But the others are not working correctly. Specifically these:
For reference, this is the output when it is not sorted:
Smith, John 610-555-7384 Barnes, Sarah215-555-3827 Riley, Mark 733-555-2969 Getz, Laura 663-555-3984 Smith, Larry464-555-3489 Phelps, Frank322-555-2284 Grant, Marsha243-555-2837
This is the output when it is sorted:
Barnes, Sarah215-555-3827 Getz, Laura 663-555-3984 Grant, Marsha243-555-2837 Phelps, Frank322-555-2284 Riley, Mark 733-555-2969 Smith, John 610-555-7384 Smith, Larry464-555-3489
This is the class Sorting, which I should note is all correct:
public class Sorting{ /** * Swaps to elements in an array. Used by various sorting algorithms. * * @param data the array in which the elements are swapped * @param index1 the index of the first element to be swapped * @param index2 the index of the second element to be swapped */ private static <T extends Comparable<? super T>> void swap(T[] data, int index1, int index2){ T temp = data[index1]; data[index1] = data[index2];
[Code]...
This is the Main class in which I am supposed to call the sorting methods, SortPhoneList:
public class SortPhoneList{ /** * Creates an array of Contact objects, sorts them, then prints * them. */ public static void main (String[] args){ Contact[] friends = new Contact[7]; friends[0] = new Contact ("John", "Smith", "610-555-7384"); friends[1] = new Contact ("Sarah", "Barnes", "215-555-3827");
I am trying to raise a real number to a negative value e.g x-y(x raised to power -y) which can also be written like 1/xk . I am trying to run th program each time bt it doesnt give me the desired result.
Here is the code
public class RaiseRealPower { public void run(){ double value =readInt("Enter value "); double power =readInt("Enter power "); System.out.println("Answer is " +raiseIntToPower(value,power));
In carrying out my little game I made a panel "Winner" in which I have two JButton plus I would like to add a blinking text to indicate the victory of the player("You win!"). Currently this text is static, designed by the function drawImage. How can I make it "flashing" maybe alternating the vision of the text (which I present in two different colors)?
I am working on a game project. Whenever we are starting our game application in production, it works perfectly around 3 days after 3 days, CPU utilization is increasing upto around 95% to 99% and application stops to respond. Before 6 days, I started application again and we doubled our Perm Gen memory size. The same problem happened but it happened after 6 days.
Now, i am not able to relate CUP utilization to Perm Gen memory. Is Perm Gen memory effect CPU utilization?
for (int w=0;w<bi.getWidth();w++) { for (int h=0;h<bi.getHeight();h++) { int color = bi.getRGB(w, h); color = color << 5; bi.setRGB(w, h, color); } }
I am using a solid green image so
11111111000000001111111100000000
I just wanted to see how it looked so bumped it over 5 places (obviously changing the color). To my surprise, there was no added transparency. I mean moving it to the left would make the alpha:
11100000
I am thinking that setRGB() doesn't effect alpha. Is this accurate?Tested it and in fact setRGB has no effect on the alpha bits. So now the question is how can I gain access to them. I am going to look into the writable Raster API. Perhaps, I can also use a modified awt to access directly OS data.
I have one jsp page in which I have listed some service records fetched from Database. I have made one of the column, for eg. Service ID to be link, which should display all the details of that service when clicked. I want those details to be displayed in lightbox. I tried doing it but when any service ID link is clicked, it displays same(First Service in record) service details.How do I pass reference of that current service to lighbox effect.
This isn't solely related to java.awt.Color, it's more of a question on how to store methods or redirections to use methods on any value passed in. To explain my question I'll describe a scenario:
ClassA is an instanstiatable class
ClassA has an instance of ClassB called cB
ClassA has methods of affecting cB
ClassD is also an instanstiatable class
ClassD has an Array[x][y] of instances of ClassA
I want to create a ClassE which I would initiate it with references to ClassA's methods or their actual methods and then I can use ClassE to easily transform ClassD's instances of ClassA by the same methods.
What I'm actually doing:
I made a class called GameColor, it has methods like changeHue, setRed, setHue, changeBrightness, setSaturation etc, these methods affect an instance of java.awt.Color in the GameColor class instances, so like they can change the hue or set it with changeHue or setHue etc...
Now I want to do something like perform a single method on a whole BufferedImage, on each of it's pixels RGB. So, I'm thinking of creating a GameColorEffects class which I store references or actual methods of GameColor like changeHue, and then I use GameColorEffects somehow to change a whole BufferedImage more efficiently, what's the most efficient way I can store methods or their reference of GameColor and then later apply them on each pixel of a BufferedImage using GameColorEffects. So all I do is initiate GameColorEffects with methods or reference from GameColor, and then I can apply it to easily transform each pixel.
I have a UI widget, like a table view for example, displaying real-time data. This table can be configured - so it has many properties. The way I would like to do so, is to have a small 'configure button', once clicked, would rotate the entire table along its y axis, and display another panel with checkboxes etc... So effectively, the hidden properties panel is revealed by rotation.
I want to work on a project related to MMO real-time strategy social game as a college project but i dont have enough knowledge on it starting from 3d object coding to server.
Also i would like to know what are things to be cosidered as its an online game whether the camera angel affect what are problems that might occur and how to outrun it. How to split the server so that in one server depending upon the geo-location some number of users will be connected and will be splitted in different servers depending on the location
I want the actions to be cloud based but the actions of the characters will be coded within the game and in every server maximum of 100 users can connect.
I wanted to know some hints on where to begin if I wanted to create a program which compares an audio file with real time captured audio. I found this website "[URL]...", but I think this would not do the job, so what are the basics of audio in java and how to compare audio files and see if they are compatible.
I have tried each and every thing in all the other answers. Like setting chunked to false, changing parameters, changing http1.1 -1.0. I am just writing a sample client to compare it with my real time client. Following is the code of client:
package com.webservicemart.ws; import java.rmi.RemoteException; import org.apache.axis2.AxisFault; import com.webservicemart.ws.USZipStub.ValidateZip; public class UsZipClient { public static void main(String[] args) {
[Code] ....
And Following is the error :
[INFO] Unable to sendViaPost to url[http://www.webservicemart.com/uszip.asmx] org.apache.axis2.AxisFault: Transport error: 404 Error: Not Found at org.apache.axis2.transport.http.HTTPSender.handleResponse(HTTPSender.java:310) at org.apache.axis2.transport.http.HTTPSender.sendViaPost(HTTPSender.java:194) at org.apache.axis2.transport.http.HTTPSender.send(HTTPSender.java:75)
[Code] ....
I have tried with other geoIP service and weather forecast too. I get the same error.
Consider the url-pattern: <url-pattern> /Beer/* </url-pattern>
The web app structure is: -
webapps | -->AdviceApp | -->WEB-INF --> {{Beer}} This can be real or virtual.
My book says that /Beer/* can be a real or a virtual directory. What is the difference between the two and how do I create a virtual directory in tomcat ?
I'm new to Web Services and I've been finding trouble when creating my first one. Before talking about the problem, I'd like to show you the process I followed to see if it's ok. Note that I'm using Eclipse Kepler, Tomcat 5.5 and Axis2.
1- I created a new Dynamic Web Project.
2- I created the Java class that implements the service with just one method, a simple one: you pass it a name and it returns "Hi, <name>"
3- Right click over that class and then: Web Services -> Create Web Service
4- I go through the next steps. On the last one, I select "Launch the Web Services Explorer to publish this Web service to a UDDI Registry". Click on "Finish".
5- The Web Services Explorer is launched, but I just get a "HTTP ERROR: 500" message.
I understand that my Web Service wasn't published and therefore it's useless to create a client as it wouldn't connect.
I have a server with a handful of php services. I communicate with these services by creating connections from java code. The services currently respond with XML, but that can be changed if an alternative way can improve performance.
One of the things I need to do is send varying sized payload (some large) to one of the services. My current plan is to create an xml file in java and perform a POST request with the XML as the payload. I am using an XML because the data is very structured.
From a performance point of view, would it be better to send the XML as a file or just as text? Also, is there a better way to send this data? These services will eventually be used by an android app, where performance and minimizing the size of the data packages will be extremely important.
import java.util.Scanner; import java.io.File; import java.io.FileNotFoundException; import java.io.PrintWriter; public class logBook { public static void main(String[] args) throws FileNotFoundException { File inputFile = new File("C:UsersNick TateDesktopLog.txt");
[Code] .....
So far this is the code I have. It will successfully read the contents of the file(which are below in quotations) and write them to the designated file. My issue is totaling the corresponding costs to their services and then writing that to the file. The if and else if clauses above do not work but how is it that I can get them working?
