I faced same issue of tomcat being too slow to start. I followed this article on DigitalOcean and installed haveged instead of using urandom. haveged is a solution which will not compromise on security. haveged allows generating randomness based on variations in code execution time on a processor. Since it’s nearly impossible for one piece … Read more
Yes, spring boot no longer relies on xml configuration and it configures an equivalent to the dispatcher servlet automatically. You can follow the following link to see how to register your filters: How to add a filter class in Spring Boot? If you use maven and not gradle, the only XML in your spring boot … Read more
You’re looking for tomcat/bin/catalina.sh run instead of tomcat/bin/startup.sh; tail -f tomcat/logs/catalina.out Tomcat stays in foreground this way (first option). If you want to shut it down, Ctrl-C in your console window will do the trick. If you choose the second option, tomcat will run in background, while tail will run in foreground, but you’ll have … Read more
Following works: apt-get install authbind First, set AUTHBIND=yes in /etc/default/tomcat7 file sudo touch /etc/authbind/byport/80 sudo chmod 500 /etc/authbind/byport/80 sudo chown tomcat7 /etc/authbind/byport/80 There was a reference URL here, but the website has been hacked (marked as unsafe in Edge, and Chrome prompts me to install a browser extension).
Assuming that you’ve downloaded and installed Tomcat as Windows Service Installer exe file from the Tomcat homepage, then check the Apache feather icon in the systray (or when absent, run Monitor Tomcat from the start menu). Doubleclick the feather icon and go to the Java tab. There you can configure the memory. Restart the service … Read more
You need to upgrade to spring 4 release to support java 1.8 byte code format
The slow startup is caused because every single class file in every single JAR file in /WEB-INF/lib is also scanned for Servlet 3.0 specific annotations. You apparently have a lot of (large) JAR files in /WEB-INF/lib. The metadata-complete=”true” indicates that the JAR files in /WEB-INF/lib doesn’t need to be scanned for Servlet 3.0 specific annotations, … Read more
You need a ResourceLink in your META-INF/context.xml file to make the global resource available to the web application. <ResourceLink name=”jdbc/mydb” global=”jdbc/mydb” type=”javax.sql.DataSource” />
This works for me: http://tomcat.apache.org/maven-plugin-2.1/ With this plugin config: <plugin> <groupId>org.apache.tomcat.maven</groupId> <artifactId>tomcat7-maven-plugin</artifactId> <version>2.1</version> <configuration> <path>/</path> </configuration> </plugin> And running with mvn clean install tomcat7:run (Please note that tomcat7:run, not tomcat:run.) Plugin documentation is here: http://tomcat.apache.org/maven-plugin-2.1/tomcat7-maven-plugin/plugin-info.html For example, the default value of additionalConfigFilesDir is ${basedir}/src/main/tomcatconf, so if you put your configs into this directory it will … Read more
The easiest solution (and what worked for me) was to delete my tomcat server from the “Servers” view in Eclipse, then create a new server and add all the appropriate modules to it. Sometimes tomcat gets confused and the easiest/least time consuming way to resolve things is to start over.
