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 have a service to save some form fields from the client and i need to add uploading image to that service using json. the service consumes json and produces json.
I am trying to hit the service which has been generated using apache cxf 3.0, I have generated the client using axis2 wsdl2java and whenever I tried to hit the service am getting as
"exception from OLB Service:org.xml.sax.SAXParseException: Content is not allowed in prolog."
Not sure about the cause of the issue. We have made interceptors on the server side to verify whether there is any special characters associated, but there are no such characters from provider.
I have a vps set up to running a MySQL database already by zpanel but when I try to connect to the database with Java I am unable to connect and receive the message:
com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure
The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server."
I have MySQL Connector(dev.mysql.com/downloads/connector/j) already added to my build and tried it with both the url and the ip. This is my connection code:
package net; import java.sql.*; import javax.swing.JOptionPane; public class LoginDatabaseConnection { Connection conn = null;
[Code] ....
The code is from youtube but when I connect to localhost it works fine however when I try to connect to the VPS the above error happens.
I am trying to connect a remote machine but I can't. There is a shared folder in the remote machine, when I write the path to file browser in local machine, it does not find the path specified. Both machines have successful network condition and ping each other. Also, the shared folder is opened to everyone, there should not be a permission problem, right?
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.

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?

I have a web service which is returning a string. I want to extend this web service so that it returns an xml based string. To begin with I am able to return xml based strings from a normal POJO class ....
I need to write a simple client to access a WS. Things I can not do :
Modify the serverAdd external jars
The client will be part of a command line call and will run as a stand alone.
I've been searching all day and have found hundreds of vague, overly complex examples, mostly based on SOAPHandler (which tells me I need to install server components which I cannot do). I grasp the general requirements but am having difficulty figuring out how to add the security elements to the header.
What do I need to do to add the username and password tokens to the header?
I'm facing some problem in my EJB setup. I have deployed the ejb setup and it was working fine.
The working conditions are:
1. The timer service is working when i hitted the servlet after starting the server. It must not work when i close the servlet window,but in my case it is still working(timer is performing its opeartion) even i closed the servlet page.
2. When i stopped the server, the timer not gets invoked.
I uninstalled the EJB application, but still the timer service is running.

I have created a sample java web service client using Apache Axis. It works well with basicHTTPbinding (without security and Basic authentication).I am not able to make a secured communication. How to make it work in a secured way using NTLM or any other security.
I have a database of 100,000 research articles, all as full text. From a GUI I'm building ( w. Scene Builder and NetBeans) I would like to enter a journal name and have some of the articles read into memory, in a background thread. Then I would analyze them, also in a background thread. Then I would write various results, e.g., lists of authors or titles, wordlists, to the GUI for examination by a user.
How to create background threads from my model that will read from and write to a GUI using Tasks and/or Services.
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.
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 need to built a file upload service which should be memory effective. I should avoid loading the entire file into memory,Since I may have multiple http request which will pile up the Heap memory. Any effective way to upload a large file(For ex:1GB file) using http Streaming. I need to do the file upload on a single http call. Let's consider a scenario where 1 GB file to be uploaded using 512MB Heap memory. Not Sure If practically I can achieve this or not.
I have just started learning about sockets and such... and i have created a chat program with a server and a client
server:
public class Server { private static ServerSocket server; private static Socket connection; private static PrintWriter pw; private static BufferedReader br; private static JTextField textOutput;
[Code] ....
so, everything is working fine . There is only one thing i would like to do now: make it so that i can run the server from my computer and then others can run the client from theirs and we will be able to chat . So I tried:
In the client code on line 56 is says:
connection = new Socket("localhost",7777);
So I changed "localhost",7777 to "myip",7777)
But when i run the server on my computer and run the client on another computer i get this error:
Why is the connection getting refused? is it for security reasons? so hackers cant connect to me or something? And is there a way to tell your computer to allow that client to connect?
