I have a java app which locally works fine but fails when packaged into a jar file.
App does following steps
App starts a docker using ProcessBuilder. Container process some files
App waits for that container to shut down and continues
App start second postgresql container in background and mounts a folder to it using Process Builder
App Waits for 5 second, just to be on safe side
App does some logic and shuts everything down.
This works fine when i ran the App inside of the IDE (InteliJ) but when I try to run it using jar file i get this error

I realize it is a weird scenario, why would you send a docker run command from inside a jar file. But i dont have other options.
Has anyone encountered this type of issue, any info would be appreciated.Thank you
How is the connection with your database configured?
It may happen that your database is not accessible from inside the container
look for extra_host in docker-compose documentation,
you may be able to add something like:
extra_hosts:
- "db_host:<your local ip, dont use 127.0.0.1 or localhost>"
then in the spring boot app
configure your spring configs, point database host to db_host instead of 127.0.0.1 or anything else

I'm working with Eureka discovery server, and when I run the app I get:
2022-05-29 20:37:54.830 ERROR 19252 --- [ restartedMain] o.s.b.d.LoggingFailureAnalysisReporter :

Description:
Web server failed to start. Port 8761 was already in use.
Action:
Identify and stop the process that's listening on port 8761 or configure this application to listen on another port.
Process finished with exit code 0
However, the port is actually free. I check in Resource monitor and also through the cmd.
Other things I tried:
Changing the port of the discovery server, and still get same thing.
Restarting pc.
Ending tasks related to JDK
My properties file of the Discovery Server looks like this:

How does your main method look like and could you post also your dependencies? From the stack trace it can be several reason for the tomcat not to start.
You could try with a differnet server port in application.properties i.e. add
server.port=8082
I want to deploy my first Java application - I have a place to deploy it. I made Spring Boot application with Tomcat. Using some web instruction I make a fat jar file (maven package). I have exceptions. I try to search for it, but any solutions isn't work for this.
What can I add - I do not setup Tomcat, simple base on maven package jar with Tomcat. Could someone tell me what I can do? I will be very grateful for your understanding and help. This is my first deploy.

Some items to check for here....
1 - Make sure you're including the Tomcat dependency in your POM.
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
</dependency>
2 - Check to see if your application.properties has the correct port number.
server.port=XXXX
3 - If this is running on a linux environment, try running the application with the following in your VM:
-Dserver.port=8181
4 - Make sure your Application Class extends SpringBootServletInitializer:
#SpringBootApplication
public class App extend SpringBootServletInitializer
{
public static void main( String[] args )
{
SpringApplication.run(App.class, "hello");
}
}
It seems that you do not configure a valid port, it should > 1024.
In my spring boot application i use spring-boot-starter-data-mongodb:2.1.3 to get coonection for MongoDB. I have some properties file to config mongoDB:
spring.data.mongodb.host=localhost
spring.data.mongodb.port=27017
spring.data.mongodb.database=database
If i set incorrect host name (spring.data.mongodb.host=incorrect host) or port my application starts successfully. But i want that application to fail as same as when i set host name with wrong format (spring.data.mongodb.host=hxxt://wrongFormat)
Caused by: com.mongodb.MongoException: host and port should be specified in host:port format
How can i do that?
Example:
application.propertires
#Wrong host
spring.data.mongodb.host=www.google.com
spring.data.mongodb.port=27017
spring.data.mongodb.database=database
DemoApplication.java:
#SpringBootApplication
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
Config.java:
#Configuration
public class Config {
#Bean
public CommandLineRunner commandLineRunner(JobRepository jobRepository ){
return args -> jobRepository.findById("1");
}
}
JobRepository.java:
public interface JobRepository extends MongoRepository<Job, String> {}
Job.java:
#Getter
#Setter
#EqualsAndHashCode
#NoArgsConstructor
#Document(collection = "Jobs")
public class Job {
#Id
private String id = null;
private String field;
}
Your issue is that the connection check on mongo happens asynchronously. So if the input is correct, the beans are all created by spring boot and the connection fails at a later point. You can force it to explode by defining a bean that checks the connection at startup. For example, I use this:
/**
* This is a testing bean. It is only here to explode when the database is not available.
* This is to counter act default spring boot behaviour where the Mongo configuration
* will connect to a localhost DB regardless of whether it exists or not.
*
*/
public class MongoDatabaseVerifier {
private static final Logger log = LoggerFactory.getLogger(MongoDatabaseVerifier.class);
public MongoDatabaseVerifier(MongoClient mongoClient) {
checkConnectionOrThrow(mongoClient);
}
/**
* Calls {#link MongoClient#getAddress()} and throws the result away if successful
* #param client
*/
void checkConnectionOrThrow(MongoClient client) {
client.getAddress(); // this will either succeed super fast or explode
log.info("Database fully started ...");
}
}
Since this bean does its check on creation, spring will only continue the startup if it succeeds. Otherwise a bean creation exception will be thrown and the startup aborted.
I hope that helps
I tried to reproduce the issue. Though it says application is started but it is getting aborted after waiting for timeout period of 30000 ms settings to connect to the cluster.
As pointed out by others, you can write some custom logic to check the connectivity or try to set decrease connectivity timeout to fail fast.

first some context:
We are developing a web application using Java 8 and springframework.
There are currently two environments in use (Test, Stage).
This works fine.
Now we wanted to add a new environment (Development).
'Development' is configured exactly like 'Test'.
The only difference is the slightly altered url.
Still we cannot start the runnable jar.
It says:

The keystore is in place and identical to the Test-keystore. Codebase and the run-scripts are identical.
I tried to look up the "tag type 60" but I cannot find any documentation nevermind someone with a related problem.
