Unable to invoke https REST endpoint through spring boot - java

I have to build a REST endpoint which is internally calling some REST Endpoints (Business Confidential) and will do some customization and give a user-specific response. Endpoints (Business Confidential) that I'm using inside the spring boot framework and support HTTP and https. Since my framework supports HTTP protocol by default.
Sample Endpoint below:
http://localhost:8081/hadoop-cal-endpoint-controller/getCustomDetails/customerID
The above endpoint which I created and internally it will call another REST Service (which support HTTP and https) and applied some custom logic and return some specific format output as Response.
I added below lines into application.yml file:
ssl:
key-store: classpath:keystore.p12
keyStoreType: pkcs12
keyAlias: tomcat
key-store-password: password
port: 8081
Used the below blog to create keystore.p12 file (copied the keystore.p12 file in src/main/resources foder):
https://www.thomasvitale.com/https-spring-boot-ssl-certificate/
I started the spring boot application using spring-boot:run command and it ran successfully. I can able to open swagger API with https protocol as look like below:
Now the problem is whenever I tried to call the endpoints using HTTP or https inside the above client that is giving the below error message
"status": 500,
"error": "Internal Server Error",
"exception": "javax.net.ssl.SSLHandshakeException",
"message": "sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target"
Everything works fine when I removed SSL and keep it as HTTP. But I just want to enable https and that endpoint will call another endpoint (Business confidential) and return a response.
Anyone, please help me on this?

Apparently, your service provider uses a self signed certificate. You either have to add the selfsigned certificate to cacerts known certificates to whitelist it or run your application with -Djavax.net.ssl.trustStore parameter
Here is details
https://stackoverflow.com/a/12146838/6785908
Quoting relevant parts here
The problem appears when your server has self signed certificate. To
workaround it you can add this certificate to the list of trusted
certificates of your JVM.
In this article author describes how to fetch the certificate
from your browser and add it to cacerts file of your JVM. You can
either edit JAVA_HOME/jre/lib/security/cacerts file or run you
application with -Djavax.net.ssl.trustStore parameter. Verify which
JDK/JRE you are using too as this is often a source of confusion.

How are SSL certificate server names resolved/Can I add alternative names using keytool?
If you run into java.security.cert.CertificateException: No name matching localhost found exception.
Or if it's just for testing purpose, why not just tell your process to skip the cert validation
like this: https://www.rgagnon.com/javadetails/java-fix-certificate-problem-in-HTTPS.html

Java application when deployed works on 8.5.20 but give java.lang.IllegalArgumentException ie null connection on tomcat 8.5.75

I am trying to upgrade version of Tomcat from 8.5.20 to 8.5.75. The application works completely fine on 8.5.20, but the same application gives me null connection in other version.
I am using Java 8. My database is Oracle 19c and I am using ojdbc8.jar. The connection details are mentioned in Tomcat conf folder in context.xml file. Am I missing anything here?

How to fix the error java.net.UnknownHostException while using Spring Boot and Eureka Server?

I have a Spring Boot microservice called "documents-microservice", which is registered in Eureka Server. I am trying to access this microservice using its name in the URL and with RestTemplate, as the following:
ResponseEntity<String> response = restTemplate.exchange("http://documents-microservice/document-name", HttpMethod.POST, entity, String.class);
Although I am sure that the service name is available on Eureka Server which is running on port 8761 (See picture below), I still get the following errors:

I/O error on POST request for "http://documents-microservice/document-name": documents-microservice; nested exception is java.net.UnknownHostException: documents-microservice
Update: Please note that I have the following method in the client for setting RestTemplate:
#Bean //this methods will be executed only once to avoid getting multiple instances.
#LoadBalanced //I will not give you service URL, but rather a hint for what you need to discover.
public RestTemplate getRestTemplate()
{
final RestTemplate restTemplate = new RestTemplate();
System.out.println("rest template defined");
return restTemplate;
}
Update: Please note that currently, my client code is not a Spring Boot Application.

There are several things that you need to do:
first: you need the RestTemplate configuration not in the client, but in the service(1) that calls that client
#Configuration
public class WebClientConfiguration {
#Bean #LoadBalanced
public RestTemplate getRestTemplate() {
return new RestTemplate();
}
}
second: you need the corresponding dependencies in the pom.xml of the same service(1)
third: add #EnableDiscoveryClient in your main application
And other configurations, but you must provide a full example to help you more.
This example can help you

You can access it by name "documents-microservice" via a #Feign client, otherwise you should try the gateway EG, hqtpm001....:8081
Furthermore, Eureka server is not the host of the application, it is more or less the traffic cop and lets you as the client know where to go to get the application. aka the Service Registry

Incase if you want to use OpenFeign instead RestTemplate
name refers to name of service registered with eureka
doctors registration service is registered with eureka server with this name doctors-registration-application.
#FeignClient(name = "doctors-registration-application") public
interface DoctorDetailsClient {
#GetMapping("/doctor/get-by-Id/{doctorId}") public Doctor
getDoctorDetails(#PathVariable int doctorId);
#GetMapping("/doctor/get-by-name/{name}") public Doctor
getDoctorDetailsByName(#PathVariable String name); }

Fabric-ca Certificate not working with tomcat

I have a centralized fabric-ca server which serves nodes requesting for crypto material. In effect the setup is as follows:
Ubuntu 16.04 running Tomcat 8 and Java 1.8
I have a servlet which will connect to fabric-ca server (On a remote machine using https and fetch the relevant certificates).
When I try to enroll a user, I get the following java error

I have tried adding the server's ca-cert.pem to tomcat's keystore (available at /opt/bitnami/apache-tomcat/java/lib/cacerts) as well as to ubuntu. Still no avail.
Am I missing something?

Issue while Authenticating user with Active Directory (using AD domain) using Spring Security from Spring-boot Application

I'm trying to authenticate the users from Active Directory by using
org.springframework.security.ldap.authentication.ad.ActiveDirectoryLdapAuthenticationProvider
CustomLdapAuthenticationProvider.java
#Override
public Authentication authenticate(Authentication authentication) throws AuthenticationException {
ActiveDirectoryLdapAuthenticationProvider activeDirectoryLdapAuthenticationProvider =
new ActiveDirectoryLdapAuthenticationProvider("companyDomain", "ldap://companyDomain:389", "rootDN");
activeDirectoryLdapAuthenticationProvider.setConvertSubErrorCodesToExceptions(true);
activeDirectoryLdapAuthenticationProvider.setUseAuthenticationRequestCredentials(true);
activeDirectoryLdapAuthenticationProvider.setSearchFilter("(userPrincipalName={0})");
activeDirectoryLdapAuthenticationProvider.setUserDetailsContextMapper(customUserDetailsContextMapper);
authentication = activeDirectoryLdapAuthenticationProvider.authenticate(authentication);
return authentication;
}
When I use IP in the url (ldap://x.x.x.x:389), authentication with AD is successful. But when I use domain in ldap url (ldap://companyDomain:389), code throws below exception

My requirement is to connect to AD and authenticate user by using AD domain.
Java/Spring allows me to do the same using IP but not domain.

It could be DNS issue, can you run dig command and check whether it resolves the ipaddress
dig companyDomain

Socket Timeout Exception In Okhttp3Client

In work, I encounter a problem like this. I used Rest-Template embedded in Spring. HttpClient used is OkHttp3Client. In On-line running, the error like below happens once an hour.It seems like socket is closed,but OkHttp3Client uses long connection to make many requests share the same connection. Who could tell my why?
#Bean("restTemplate")
public RestTemplate getRestTemplate() {
OkHttp3ClientHttpRequestFactory clientHttpRequestFactory = new
OkHttp3ClientHttpRequestFactory();
clientHttpRequestFactory.setConnectTimeout(CONNECT_TIMEOUT_MILLISECONDS);
clientHttpRequestFactory.setReadTimeout(READ_TIMEOUT_MILLISECONDS);
RestTemplate restTemplate = new RestTemplate();
restTemplate.setRequestFactory(clientHttpRequestFactory);
return restTemplate;
}
The error info:
org.springframework.web.client.ResourceAccessException: I/O error on POST
request for "http://*****": timeout; nested exception is java.net.SocketTimeoutException: timeout
