just placing the query in the browser returns a response but through my program, I get an error. If someone can hellp I would be grateful.
Im creating a rest service
First you have to use InputStream since you are reading data from the response. Second, you have to accept as json response for that you have to use conn.setRequestProperty("Accept", "application/json");
I have modified your program, please check.
public class PopulationService {
public static void getPopulation() {
String query_url =
"https://data.opendatasoft.com/api/records/1.0/search/?dataset=world-population#kapsarc&facet=country_name&facet=year&refine.country_name=Australia&refine.year=2000";
try {
URL url = new URL(query_url);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestProperty("Accept", "application/json");
conn.setDoOutput(true);
conn.setRequestMethod("GET");
conn.connect();
BufferedReader br = new BufferedReader(new InputStreamReader(
(conn.getInputStream())));
String output;
System.out.println("Response Server .... \n");
while ((output = br.readLine()) != null) {
System.out.println(output);
}
conn.disconnect();
int status = conn.getResponseCode();
System.out.println("Status Code: "+status);
} catch (Exception e) {
System.out.println(e);
}
}
public static void main(String args[]) {
getPopulation();

I think your problem is that you don't have the table reservation in your database. Try creating it.
These are exceptions I'm facing

I'm beginner please help me!
I'm glad that you joined stack overflow. This error has nothing to do with your Java code. The error code says:
java.sql.SQLException: Cannot create PoolableConnectionFactory (Public Key Retrieval is not allowed)
All you need to do is set up a username and password to connect to your database.
I've a .mdb access file and I'm indexing the datas to my solr core. I wrote this java class to index them in solr core. When I'm running this java class as java application, it works fine but when I'm running server side it's not working.

Is there any mistake or something?? How can I call the java class in my .jsp file?
You have to move the Driver in the JRE/lib/ext
I want to add a Correlation-Id header to all responses by using a Spring filter.
It worked great so far, but if I call a route which does not match to a resource I get a java.lang.IllegalStateException exception.
My filter looks like this:
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.core.annotation.Order;
import org.springframework.stereotype.Component;
import org.springframework.web.filter.OncePerRequestFilter;
import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.util.UUID;
public class AttachCorrelationIdHeaderFilter extends OncePerRequestFilter {
private static final Logger LOGGER = LoggerFactory.getLogger(AttachCorrelationIdHeaderFilter.class);
private String correlationIdHeaderName = "";
public AttachCorrelationIdHeaderFilter(String correlationIdHeaderName) {
this.correlationIdHeaderName = correlationIdHeaderName;
}
#Override
protected void doFilterInternal(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, FilterChain filterChain) throws ServletException, IOException {
String correlationId = httpServletRequest.getHeader(this.correlationIdHeaderName);
if (correlationId == null || correlationId.isEmpty()) {
correlationId = UUID.randomUUID().toString();
LOGGER.debug("Generated new Correlation-Id {}", correlationId);
} else {
LOGGER.debug("Use existing Correlation-Id {}", correlationId);
}
httpServletResponse.addHeader(this.correlationIdHeaderName, correlationId);
filterChain.doFilter(httpServletRequest, httpServletResponse);
}
}
and will be registered in a simple configuration class:
import *.AttachCorrelationIdHeaderFilter;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.web.servlet.FilterRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
#Configuration
public class CorrelationConfiguration {
private String correlationIdHeaderName;
public CorrelationConfiguration(#Value("${usagebox-scs.headers.correlation-id}") String correlationIdHeaderName) {
this.correlationIdHeaderName = correlationIdHeaderName;
}
#Bean
public FilterRegistrationBean attachCorrelationIdFilter() {
final FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean<AttachCorrelationIdHeaderFilter>();
final AttachCorrelationIdHeaderFilter attachCorrelationIdFilter = new AttachCorrelationIdHeaderFilter(correlationIdHeaderName);
filterRegistrationBean.setFilter(attachCorrelationIdFilter);
filterRegistrationBean.setOrder(-1);
return filterRegistrationBean;
}
}
The exception looked like this:
java.lang.IllegalStateException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request.

Thanks for any help!
This is probably a common question but I can't figure it out.
I have this URL which returns the expected ticket detail if I plug it into a browser, so I know it is working:
https://www.myconnectwise.net/v4_6_release/services/system_io/integration_io/processClientAction.rails?actionString=%3C%3Fxml%20version%3D%221.0%22%20encoding%3D%22utf-16%22%3F%3E%0A%3CGetTicketAction%20xmlns%3Axsi%3D%22http%3A%2F%2Fwww.w3.org%2F2001%2FXMLSchemainstance%22%20xmlns%3Axsd%3D%22http%3A%2F%2Fwww.w3.org%2F2001%2FXMLSchema%22%3E%0A%3CCompanyName%3Exxxxxxx%3C%2FCompanyName%3E%3CIntegrationLoginId%3Exxxxxx%3C%2FIntegrationLoginId%3E%3CIntegrationPassword%3Exxxxxx%3C%2FIntegrationPassword%3E%0A%3CSrServiceRecid%3E1921%3C%2FSrServiceRecid%3E%3C%2FGetTicketAction%3E
For a more readable version it is this URL:
https://www.myconnectwise.net/v4_6_release/services/system_io/integration_io/processClientAction.rails
Followed by:
?actionString=
Followed by this xml:
<?xml version="1.0" encoding="utf-16"?>
<GetTicketAction xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<CompanyName>xxxx</CompanyName><IntegrationLoginId>xxxx</IntegrationLoginId><IntegrationPassword>xxxx</IntegrationPassword>
<SrServiceRecid>1921</SrServiceRecid></GetTicketAction>
I am having problems putting this into code and getting it to work.
I get this error:

I have got 'Server returned HTTP response code: 500 for URL: myconnectwise.net/v4_6_release/services/system_io/…; after executing of your code.
So check server (500 - Internal Server Error).
And analyze response code before parsing result as XML.
