NoClassDefFoundError: com/couchbase/client/java/error/TemporaryFailureException - java

I am using OpenJDK 11.0.5 java version and couchbase java client version 2.6.0. It works when called through a main class but when I am hitting through my api, it throws NoClassDefFoundError. Full stack trace below :
I am just calling a method from another jar, no modifications whatsoever. The jar works well separately. I checked my code against the master branch, no changes in that.
I tried upgrading the couchbase client version to latest 3.x.x but in vain. Can anyone please suggest what I am missing?

Solved it. The problem was due to multiple versions of couchbase java-client. The main application has one version and the jar has other. Made all the java-client versions consistent and it worked. I used 2.6.0 as the java-client version.

How to solve Query failed with error code 13 and error message 'command find requires authentication'

I'm getting this error when making requests to my spring boot api hosted on a Vultr VPS. I enabled authentication in the mongod.conf file. Afterward, I added a user to the admin database called dbOwner with the dbOwner role. I can connect to the database via Robo3t, but my spring boot api is having trouble doing the same.
My application.properties is as such. Would prefer to use mongodb uri, but haven't gotten that far yet.
spring.data.mongodb.authentication-database=admin
spring.data.mongodb.database=my_db
spring.data.mongodb.host=localhost
spring.data.mongodb.port=27017
spring.data.mongodb.user=dbOwner
spring.data.mongodb.password=secret
server.port=80

I'm utterly and completely confused because I've never changed the authentication settings in the mongod.conf before therefore other projects I've worked on haven't actually required authentication to connect. I'm adding the authentication in response to a hack that occurred on my empty database since it had no auth. Any help would be greatly appreciated.

Java HttpClient - allowing restricted headers does not work [duplicate]

How to customise "host" header in Java http client

Closed 2 years ago.
I am trying to set Connection and Host header in my request builder, but when I want to send this request, I get java.lang.IllegalArgumentException: restricted header name: "Host" exception.
I tried to set jdk.httpclient.allowRestrictedHeaders=host in application.properties, pass
-Djdk.httpclient.allowRestrictedHeaders=host argument to JVM and create net.properties file with jdk.httpclient.allowRestrictedHeaders=host property, but nothing worked for me.

JDK version - 11.0.7
Do you have any suggestion, how to set these headers?
Thanks

You can set these parameters using System property before you call HttpClient.
static void main(String[] args) {
System.setProperty("jdk.httpclient.allowRestrictedHeaders", "Referer");
System.setProperty("jdk.httpclient.redirects.retrylimit", "3");
System.setProperty("jdk.httpclient.disableRetryConnect", "true");
System.setProperty("jdk.httpclient.enableAllMethodRetry", "true");
System.setProperty("jdk.httpclient.allowRestrictedHeaders", "Content-Length");
System.setProperty("jdk.internal.httpclient.disableHostnameVerification", "true");
System.setProperty("org.apache.tomcat.util.buf.UDecoder.ALLOW_ENCODED_SLASH", "true");
System.setProperty("tomcat.util.http.parser.HttpParser.requestTargetAllow", "|{}");
SpringApplication.run(Application.class, args);
}

Nested exception is java.lang.NoSuchMethodError: 'long com.google.common.io.ByteStreams.exhaust(java.io.InputStream)'] [duplicate]

This question already has answers here:
java.lang.NoSuchMethodError: com.google.common.io.ByteStreams.exhaust(Ljava/io/InputStream;)J

Can anyone please help me to resolve below issue. Just yesterday, It was working fine and suddenly I got below error. I tried to remove StoredCredential file and generate new one but same error. I tried to add latest guava dependency in pom.xml but no luck. I don't know what changed suddenly. Thank you for looking into this. Below is stack trace.

From above dependency, I have comment out the version and it started working.

UnsatisfiedLinkError when try to use google or-tools with spring

i need to write simple TSP-solver service for my project
or-tools solver works with simple static main class, but when i try to include it as service in spring i get
java.lang.UnsatisfiedLinkError: 'void com.google.ortools.constraintsolver.mainJNI.swig_module_init()'
public class TravelingSalesmanExample2 {
public static void main(String[] args) {
System.loadLibrary("jniortools");
...
works perfect, but when i try to call methods from or-tools within spring poject as #Service or even like this
#SpringBootApplication
public class Application {
public static void main(String[] args) throws IOException {
SpringApplication.run(Application.class, args);
TravelingSalesmanExample2.main(null);
}
}
i have this error

I have tried add or-tool as maven dependency as described here https://github.com/oliviercailloux/google-or-tools-java
tried add argument -Djava.library.path=/Users/vitaliy/Desktop/backend/lib
tried load as System.load("/Users/vitaliy/Desktop/backend/lib/libjniortools.jnilib");
but not succeed. any idea how to make native libs visible for spring-served application?
UPD OS: mac os catalina 10.15.3

Check out my answer here, I'm using google or-tools as a part of a spring-boot application over intellij.

#SpringBootApplication
public class Application {
static{
System.loadLibrary("jniortools");
}
public static void main(String[] args) throws IOException {
SpringApplication.run(Application.class, args);
TravelingSalesmanExample2.main(null);
}
}

getForEntity returns null

I try to write java service using spring boot. Here is the my code. The thing is I am getting null all the time. Where is the missing part in my code ?
#RestController
public class CurrencyConversionController {
#GetMapping("/currency-converter/from/{from}/to/{to}/quantity/{quantity}")
public CurrencyConversionBean convertCurrency(#PathVariable String from,
#PathVariable String to,
#PathVariable BigDecimal quantity){
Map<String,String> uriVariables = new HashMap<>();
uriVariables.put("from",from);
uriVariables.put("to",to);
ResponseEntity<CurrencyConversionBean> responseEntity = new RestTemplate().
getForEntity("http://localhost:8000/currency-exchange/from/{from}/to/{to}",
CurrencyConversionBean.class,
uriVariables);
CurrencyConversionBean response = responseEntity.getBody();
return new CurrencyConversionBean(response.getId(),from,to,response.getConvertionMultiple(),quantity,
quantity.multiply(response.getConvertionMultiple()),
response.getPort());
}
}
Here is the error I got;
rror on GET request for "http://localhost:8888/currency-conversion-service/default": Connection refused: connect; nested exception is java.net.ConnectException: Connection refused: connect

com.example.currencyconversionservice.CurrencyConversionBean#43bfd139****************************
null---------------------------------
As the error states it gives null pointer exception. I am following udemy course. This code from this course.
This is my first java service application and I could not figure out the problem. Any help is appreciated. Thank you.

I think that
response.getConvertionMultiple() == null
that why you have java.base/java.math.BigDecimal.multiply(BigDecimal.java:1512) in your stackTrace, it's happened when you trying to multiply "quantity" by your "response.getConvertionMultiple()" which is null.
So clearly you have to check if (response.getConvertionMultiple() == null) // do something.

Does Java even have String interpolation?
Change the getforEntity line:
getForEntity("http://localhost:8000/currency-exchange/from/"+from+"/to/"+to)

It may be bit late for reply, But might be useful for someone hopefully.
Here output of currency-exchange is not able to map to CurrencyConversionBean,
ResponseEntity<CurrencyConversionBean> responseEntity = new RestTemplate().
getForEntity("http://localhost:8000/currency-exchange/from/{from}/to/{to}",
CurrencyConversionBean.class,
uriVariables);
Solution here can be, check bean variables fro both mocroservices, it must be same in order to map its output to CurrencyConversionBean. hopefully this helps.
