I'm using NetBeans IDE and Maven with Spring Boot. Whenever I run my app more than once, I get this error:
o.a.coyote.http11.Http11NioProtocol : Failed to start end point associated with ProtocolHandler ["http-nio-8080"]
java.net.BindException: Address already in use
spring boot java.lang.IllegalStateException: Tomcat connector in failed state
I'm assuming this means that Tomcat isn't getting shutdown. How can I properly shutdown the embedded Tomcat in Spring Boot (preferably from the IDE)?
I found a netbeans configuration that fixed my problem. See this screenshot: https://bugzilla-attachments-241321.netbeans.org/bugzilla/attachment.cgi?id=151222

I'm running my Spring Boot application with debug mode enabled. Like:
mvn -P dev spring-boot:run -Drun.jvmArguments="-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5005"
I can debug the application after that without any problem. But, after stopped (ctrl + c) and try to start again, I receive this error:
[INFO] Attaching agents: []
ERROR: transport error 202: bind failed: Address already in use
ERROR: JDWP Transport dt_socket failed to initialize, TRANSPORT_INIT(510)
JDWP exit error AGENT_ERROR_TRANSPORT_INIT(197): No transports initialized [debugInit.c:750]
So, every time that I need to start the application in debug mode after that, I need to kill the process using the port 5005.
I would like to know why the port 5005 is still opened after stop the application.
I'm using Cygwin64 on Windows 10, Maven 3.5.2, Java 8 and Spring Boot 1.5.9.RELEASE.
Thanks!
This is not a problem of Spring Boot, but a problem of non-cygwin applications running in cygwin. And your application is not only leaving port 5005 open, it just keeps running in the background, having port 8080 also opened, but as on a restart the debug port is first opened, this is what you see in the error message.
This was discussed in a SpringBoot issue back in 2014 https://github.com/spring-projects/spring-boot/issues/773. I cite from this issue (the link in the citation dates from 2006):
Anyone still following this bug, this isn't a Spring Boot bug at all. It's a known problem with non-Cygwin programs (Java in this case) running on pty-based terminals.
See this link for a full explanation why this can't be fixed: http://cygwin.com/ml/cygwin/2006-12/msg00151.html
So you can basically use one of the following approaches:
use the native windows terminal and setup your java and maven environment for that
run your maven command from within an IDE which can handle this - you might use this for debugging as well
add the Spring Actuator to your app and use the /shutdown endpoint to stop your application
I have deployed my first spring boot web application executable jar in self contained tomcat server successfully and accessing it on port 8080 but when I deployed my second app on different port using init.d on port 42000 I am unable to access it. I have looked the log in /var/log the application starts successfully without any errors. What would be the causes for my problem?
Trying to deploy Midpoint OpenSource IDM software on Windows server
Runing JAVA 9.0.1 and Tomcat Apache 8.5
Deployment of the WAR file seems to succeed but application does not start
On Tomcat Web Application Manager I get the error:
FAIL - Application at context path [/midpoint] could not be started
In the Catalina logs all I can see is:
SEVERE [http-nio-8080-exec-38] org.apache.catalina.core.StandardContext.startInternal One or more listeners failed to start. Full details will be found in the appropriate container log file
SEVERE [http-nio-8080-exec-38] org.apache.catalina.core.StandardContext.startInternal Context [/midpoint] startup failed due to previous errors
I have deployed my application in jboss-4.0.2RC1. It is working fine. But after some time unexpectedly jboss is getting shutdown.
Please find the below logs
2015-09-21 21:09:28,995 INFO [org.jboss.system.server.Server] JBoss SHUTDOWN: Undeploying all packages
2015-09-21 21:09:28,995 DEBUG [org.jboss.deployment.scanner.AbstractDeploymentScanner$ScannerThread] Notified to shutdown
2015-09-21 21:09:28,996 DEBUG [org.jboss.deployment.MainDeployer] Undeploying
I am not able to find the root cause?
Please suggest
What operating system is hosting your jboss? There are a number of reasons this could happen depending on your configuration. For instance, if you are running on Windows and running JBoss as a service, it will shutdown upon server logoff, unless you have added to your run.conf.bat something like:
set JAVA_OPTS=%JAVA_OPTS% -Xrs
I modified the web.xml file from a dynamic web project in Eclipse EE and now I can't start the Tomcat server.
Error shows:
Server Tomcat v8.0 Server at localhost failed to start.
and in the console:
SEVERE: Failed to destroy end point associated with ProtocolHandler ["ajp-nio-8009"]
How can i fix this ?
The service is already running on port 8009. You should kill it and try tomcat restart.
Try this :
Terminate the tomcat, restart it from command prompt and then first undeploy and then redeploy your web application.
