1]Some people on the internet say there are two possible reasons for this problem:1) If you are using Tomcat 7, you need to modify the URL address of the deployment in Pom.xml.Switch2) Tomcat User Rights assignment problem, need to have both Manager-gui and Manager-script permissions, such as forget to assign Manager-script permissions.The correct conf/tomcat-users.xml configuration should be:But my problem is not the above two, my problem is the automatic deployment command is wrong, should be

MyEclipse CI as a popular javaide development tool, it has a lot of useful features for our development to provide help.

the public static URL Getextendresource (String relativepath) method of the Classloaderutil class above, you have been able to locate resources for all locations using relative paths to classpath.4. Never use a hard-coded absolute path. Because, we can use the ClassLoader class's GetResource ("") method to get the absolute path of the current classpath. If you must specify an absolute path, then using a configuration file is much better than hard coding!To obtain a path outside of Classpath:URL

Based on GitHub programming: 13 Java projects not to be missedToday we are going to tidy up a lot of dry Java sample Code and ability to display footage.GitHub is a great treasure trove of programs, some of which are worth the fork, and others that can help us improve our own code or learn programming skills. In any case, it's almost impossible for us to get arou

Many application servers have operating system configuration items or non-standard features related to the Java EE specification, which can improve system performance. It should be time to unders

The directory structure of the general web system is as follows, where the package structure under SRC and the folders under Webroot (except Meta-inf and Web-inf) can be actually adjusted according to their own projects, but the large directory structure of the Java EE specification will not change:Meta-inf: Exactly what to do withMeta-inf, to put it bluntly, is to store some meta-information related files

If you are not sure how you should choose a specific plan, be sure to refer to this list, which even divides the entries by category.It also includes some of the old tools that are still in use, including frameworks that simplify mapping, tools to build application cycles and dependencies, libraries that handle bytecode programming, and so on.Concluding remarksThis is, of course, just the tip of the iceberg of GitHub, and there is no doubt that m
