Here is the rest ws POST method code:
#POST
#Path("/json/saveuser")
#Consumes("application/json")
public ResponseBuilder saveUserJSON(User user) {
if (save(user)) {
return Response.status(HttpStatus.SC_OK);
}
return Response.status(HttpStatus.SC_BAD_REQUEST);
}
User is saved properly in DB.
But the line Response.status(HttpStatus.SC_OK); and Response.status(HttpStatus.SC_BAD_REQUEST);, is throwing below error:

Not sure what am I missing? Any suggestion?
You have to return a Response instead of a ResponseBuilder:
#POST
#Path("/json/saveuser")
#Consumes("application/json")
public Response saveUserJSON(User user) {
if (save(user)) {
return Response.status(HttpStatus.SC_OK).build();
}
return Response.status(HttpStatus.SC_BAD_REQUEST).build();
}
Your stacktrace obviously points, that Jersey doesn't know, how to response with ResponseBuilder.
Return Response instead: change resource method signature and return result of build method, called upon builder.

you would have use correct version if you want proper output latest version number is 1.19.1 use this try onee
May be problem with servelet api dependcy :
use this in your maven pom for exemple:
<!-- servlet api 3 -->
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.0.1</version>
</dependency>
Its seems a java version issue. compile the code with supporting jar(java version) only
Background Information
I have a Spring Boot web application using Actuator for the production utilities.
The application works fine, and the management port works great. I can browse statistics, check health etc. I also enabled the remote shut-down endpoint, and it properly shows up in the localhost:{mgmt_port}/actuator list of endpoints.
My Problem
When I go to localhost:{mgmt_port}/shutdown though, I see:
<Map>
<timestamp>1453905900007</timestamp>
<status>500</status>
<error>Internal Server Error</error>
<exception>org.springframework.web.HttpRequestMethodNotSupportedException</exception>
<message>Request method 'GET' not supported</message>
<path>/shutdown</path>
</Map>
Useful Information
The whole application still seems to be running after hitting the shut-down link. I can still pull data from my custom application endpoints.
The management URL provided by Spring actuator also seems to still be running fine after hitting shut down.

Answering my own question to help others in the future. I'm a chump... The /actuator URL lists all available commands, and all of them work based on a GET request.
The /shutdown URL actually requires a HTTP POST to be sent to it in order to activate it though. I didn't see this noted anywhere in the docs.
Sample CURL Command:
> curl -X POST http://hostname:8003/shutdown
Output Of Shutdown Command:
<SingletonMap><message>Shutting down, bye...</message></SingletonMap>
I'm having an OpenShift site which is trying to connect to an external MySQL server. Below is the code I have so far.
public class BaseDAO {
static final String DB_DRIVER = "com.mysql.jdbc.Driver";
DataSource datasource;
public BaseDAO() {
System.out.println("+++++ " +Calendar.getInstance().getTime());
try{
InitialContext ic = new InitialContext();
Context initialContext = (Context) ic.lookup("java:comp/env");
datasource = (DataSource) initialContext.lookup("jdbc/MySQLDS");
Class.forName(DB_DRIVER).newInstance();
} catch(Exception e){
e.printStackTrace();
throw new RuntimeException(e.getCause());
}
}
}
All my DAO classes extend the BaseDAO so I won't have to type all of this 5-6 times.
After some configuration, this does work on a local MySQL server. I have created a small application that either sends me to the index.jsp when the array gathered from the database is not null or not empty, and sends me to the about.jsp if it either is empty or null.
Now in both the local and the external database I have create a table with the same name, column 'day' and inserted 1 value. When I run this locally it sends me to the index page, but when I run this via my OpenShift webpage it sends me to the about page.
This is the error found in the SSH/app-root/logs/jbossews.log (username and serverip commented out)
:
NOTE: THE SERVERIP AND LOGINCREDENTIALS ARE PROVIDED BY THE DATASOURCE OF OPENSHIFT
The path to the DAO is: OpeningsTijdenServlet --> (static)ServiceProvider --> OTService --> OpeningsTijdenDAO (extends BaseDAO)

Something wrong with your credential. try to change credential or server configuration.
Any of the hosting server you have to select "localhost"/"127.0.0.1" as your DB Host.
I have a class that implements javax.servlet.Filter and inside that filter, I'm instantiating an instance of InterceptHttpRequestFilter and InterceptHttpResponseFilter (which are used to modify the incoming and outgoing request and response)
Example:
public class InterceptHttpRequestFilter implements HttpServletRequest {
private HttpServletRequest httpReq;
final StringBuffer sb = new StringBuffer();
public InterceptHttpRequestFilter(ServletRequest request) {
this.httpReq = (HttpServletRequest) request;
try {
StringWriter sw = new StringWriter();
IOUtils.copy(request.getInputStream(), sw);
sb.append(sw.getBuffer().toString());
} catch (IOException e) {
e.printStackTrace();
}
}

The obvious solution is to implement all the missing methods required by Servlet Version 3's HttpRequest / Response interfaces.
The maven dependency on mvnrepository is still in alpha:
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>3.0-alpha-1</version>
</dependency>
So my question is, does middle ground exist that will allow me to run this project on both Tomcat6 (Servlet 2.5) and Tomcat7 (Servlet 3.0) without having to tinker with my InterceptHttpRequestFilter and InterceptHttpResponseFilter ?
That's why it's recommended to extend HttpServletRequestWrapper instead of implementing HttpServletRequest directly.
HttpServletRequestWrapper has implementations of all required methods, therefore it should solve the problem.
The following code:
#POST
#Path("/previous-status/{current}")
#Consumes(MediaType.APPLICATION_XML)
#Produces(MediaType.TEXT_PLAIN)
public String getPreviousStepStatus(#PathParam("current") JAXBElement<WorkflowStep> step) {
WorkflowStep wfStep = step.getValue();
return DBAccessor.getPrevStepStatus(wfStep);
}
Produces the following exception:

If it is commented I don't get the exception. The currently used libraries in the web application are:
asm-3.1.jar
jersey-core-1.11.jar
jersey-server-1.11.jar
jsr311-api-1.1.1.jar
jersey-servlet-1.11.jar
activation.jar (part of jaxb distribution)
jaxb-api.jar
jaxb-impl.jar
stax-api-1.0.1.jar
woodstox-core-asl-4.1.2.jar
The reason I have included the last 5 libraries in the list is this article from developer works
Furthermore from the tomcat start up log I see the following:
SEVERE: The following errors and warnings have been detected with resource and/or provider classes:
SEVERE: Missing dependency for method public java.lang.String restful.SilverLine.getPreviousStepStatus(javax.xml.bind.JAXBElement) at parameter at index 0
SEVERE: Method, public java.lang.String restful.SilverLine.getPreviousStepStatus(javax.xml.bind.JAXBElement), annotated with POST of resource, class restful.SilverLine, is not recognized as valid resource method.
Any ideas will be appreciated?
PathParameter and entity is something different, try following:
#POST
#Path("/previous-status/{order}")
#Consumes(MediaType.APPLICATION_XML)
#Produces(MediaType.TEXT_PLAIN)
public String getPreviousStepStatus(#PathParam("order") int order, JAXBElement<WorkflowStep> step) {
...
WorkflowStep wfStep = step.getValue();
return DBAccessor.getPrevStepStatus(wfStep);
}
in this case, you can do requests like POST http://host/previous-status/10 and put whatever you want into entity.
You had xml in path param (which is part of URL), which is not possible to use. Your request would look like POST http://host/previous-status/<some-xml><foo>bar</foo></some-xml > , which is .. not good idea and not supported.
You should take a look at Jersey user guide: http://jersey.java.net/nonav/documentation/latest/ , topics like path param injection, accessing entity and working with XML are well covered there.
