I've been using the following guide to develop a hello world REST web service.
The guide can be found at: http://wiki.eclipse.org/Creating_a_JAX-RS_Web_Service
I'm trying to open the path: "http://localhost:8080/BeezerServer/jaxrs/addresses"
but it keeps on saying that "The requested resource (/BeezerServer/jaxrs/addresses) is not available."
my web.xml:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web- app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">
<display-name>BeezerServer</display-name>
<servlet>
<description>JAX-RS Tools Generated - Do not modify</description>
<servlet-name>JAX-RS Servlet</servlet-name>
<servlet-class>org.apache.wink.server.internal.servlet.RestServlet</servlet-class>
<init-param>
<param-name>javax.ws.rs.Application</param-name>
<param-value>com.test.AddressBookApplication</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>JAX-RS Servlet</servlet-name>
<url-pattern>/jaxrs/*</url-pattern>
</servlet-mapping>
</web-app>
The project looks as following(in case it might help someone):

I am creating simple REST API with spring mvc, but when I go to http://localhost:8080/fundnesia/api/loans I got noHandlerFound eror. Seems like spring doesnt register these #RestController, #RequestMapping and #PostMapping, #DeleteMapping annotations. Any help please
Here is my entity class
package com.fundnesia.entity;
import java.math.BigDecimal;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
#Entity
#Table(name="loan")
public class Loan {
#Id
#GeneratedValue(strategy =GenerationType.IDENTITY)
#Column(name="id")
private int id;
#Column(name="tenure")
private int tenure;
#Column(name="ticket_size")
private BigDecimal ticketSize;
#Column(name="fee")
private BigDecimal fee;
#Column(name="total_loan")
private BigDecimal totalLoan;
#Column(name="installment_per_month")
private BigDecimal installmentPerMonth;
#Column(name="status")
private String status;
public Loan() {
}
public Loan(int tenure, BigDecimal ticketSize, BigDecimal fee, BigDecimal totalLoan, BigDecimal installmentPerMonth,
String status) {
this.tenure = tenure;
this.ticketSize = ticketSize;
this.fee = fee;
this.totalLoan = totalLoan;
this.installmentPerMonth = installmentPerMonth;
this.status = status;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public int getTenure() {
return tenure;
}
public void setTenure(int tenure) {
this.tenure = tenure;
}
public BigDecimal getTicketSize() {
return ticketSize;
}
public void setTicketSize(BigDecimal ticketSize) {
this.ticketSize = ticketSize;
}
public BigDecimal getFee() {
return fee;
}
public void setFee(BigDecimal fee) {
this.fee = fee;
}
public BigDecimal getTotalLoan() {
return totalLoan;
}
public void setTotalLoan(BigDecimal totalLoan) {
this.totalLoan = totalLoan;
}
public BigDecimal getInstallmentPerMonth() {
return installmentPerMonth;
}
public void setInstallmentPerMonth(BigDecimal installmentPerMonth) {
this.installmentPerMonth = installmentPerMonth;
}
public String getStatus() {
return status;
}
public void setStatus(String status) {
this.status = status;
}
#Override
public String toString() {
return "Loan [id=" + id + ", ticketSize=" + ticketSize + ", fee=" + fee + ", totalLoan=" + totalLoan

Issue:
After receiving a message from a the MessageListener class adds a message to a private final ObservableList<String> which in turn updates the GUI on change. the problem is that this happens inconsistently and for some unknown reason there seems to be 2 lists that interchange in adding the message to its list.
here is a log of this behavior:

If I mock the MessageListener class to just add a String every few seconds the log shows 2 lists that have the same size.

I have implemented simplecart to my project.
On clicking the checkout button it went to PayPal which I didn't wanted it to. So I changed the action URL in simplecart.js file to point to my servlet
action = opts.sandbox ? "cart_checkout" :"cart_checkout",
method = opts.method === "GET" ? "GET" : "POST";
It calls the servlet but I get a NumberFormatException in my servlet

You should capture the request that is being sent to your webservice.
In the error you can see that you get a NumberFormatException: null. This suggests that your count String is null.
String count=request.getParameter("ItemCount");
This can happen when ItemCount is not a parameter of your request.
It would be good practice to test count (= "ItemCount" parameter) for null values in your code, so that you can return a nice looking error to your client.
It is because your count variable is null you can avoid it by
String count=request.getParameter("ItemCount");
if(count.length()>0){
int cnt=Integer.parseInt(count.trim());
// other logic
}
else{
//do nothing
}
The cause of the problem is quite straightforward:
int cnt=Integer.parseInt(count);
this is pointed out clearly from your stack trace:
at com.kunal.servlet.CartCheckout.doPost(CartCheckout.java:53)
A simple solution would be to check the count against null, hence change your doPost (..) implementation into:
/**
* #see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
*/
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
String count=request.getParameter("ItemCount");
ArrayList<String> item_detail=new ArrayList<String>();
int cnt= count == null 0 : Integer.parseInt(count);
for(int i=1;i<cnt+1;i++)
{
String name=request.getParameter("item_name_");
item_detail.add(name);
String price=request.getParameter("item_price_");
item_detail.add(price);
String qty=request.getParameter("item_quantity_");
item_detail.add(qty);
}
}
In order to ensure that you'll not encounter the same issue with empty strings, you can check also for empty strings. If using other libraries is an option I would suggest using StringUtils.isNotBlank(..)
then your parsing line becomes:
int cnt= StringUtils.isNotBlank(count) 0 : Integer.parseInt(count);

In your configuration file add this property:
<property name="hibernate.hbm2ddl.auto" value="update" />
and also, very useful are these:
<property name="hibernate.show_sql" value="true" />
<property name="hibernate.format_sql" value="true" />
From Hibernate docs
Change your configuration file property as below
<property name="hibernate.hbm2ddl.auto" value="create"/>
instead of
<property name="hbm2ddl.auto">true</property>
I inject a invoke statement(cajolingMe.cajoleMe();) to One of the webgoat's class(HammerHead.class). This method is a static method that called from a jar file which crated by fat-jar. I copy that jar to lib directory of [webgoat][3] web application.
When I decompile injected class there are no problem and syntax is true.
(injected codes bolded)
