How to start Tomcat on more than one Port. Tomcat settings can be found in TomcatFolder/conf/server.xml file. Root element of the configuration is Server tag. You can add multiple Service under Server tag for running tomcat on more than one port. Default Service Configuration should look as follows < Service name = "Catalina" > < Connector port = "8080" protocol = "HTTP/1.1" connectionTimeout = "20000" redirectPort = "8443" /> < Connector port = "8009" protocol = "AJP/1.3" redirectPort = "8443" /> < Engine name = "Catalina" defaultHost = "localhost" > < Realm className = "org.apache.catalina.realm.LockOutRealm" > < Realm className = "org.apache.catalina.realm.UserDatabaseRealm" resourceName = "UserDatabase" /> </ Realm > ...

Following Gradle task will list the files inside a zip file, jar file and a tar file at the location "src/main/resources/archives/" task showFiles(){ doLast{ FileTree zipFiles = zipTree("src/main/resources/archives/resources.zip"); FileTree jarFiles = zipTree("src/main/resources/archives/resources.jar"); FileTree tarFiles = tarTree("src/main/resources/archives/resources.tar.gz"); println " \n#Contents of Zip ...

Difference Between File, FileCollection and FileTree in Gradle File FileCollection FileTree File is from java.io package FileCollection is from org.gradle.api.file package FileTree is from org.gradle.api.file package File represents a single file. FileCollection represents a collection of files FileTree represents hierarchy of files in a directory or folder. Difference Between File, FileCollection and FileTree Suppose we have a directory structure as shown in image below. We can write a gradle task as shown below task loadFiles(){ doLast{ File file = file('src/main/resources/sample1.txt') println file.name println "\n" FileCollection collection = files('src/main/resources/sample1.txt','src/main/resources/sample2.txt') collection.each { println it.name } println "\n" FileTree tree = fileTree('src') tree.each { println it.name ...
