Either open the project in the IDE and assign the server or setup the server classpath manually. For example like this: ant -Dj2ee.server.home=<app_server_installation_directory> The Java EE server classpath is not correctly set up. Your active server type is ${j2ee.server.type}. Either open the project in the IDE and assign the server or setup the server classpath manually. For example like this: ant -Duser.properties.file=<path_to_property_file> (where you put the property "j2ee.platform.classpath" in a .properties file) or ant -Dj2ee.platform.classpath=<server_classpath> (where no properties file is used) Must set javac.includes No tests executed. The libs.CopyLibs.classpath property is not set up. This property must point to org-netbeans-modules-java-j2seproject-copylibstask.jar file which is part of NetBeans IDE installation and is usually located at <netbeans_installation>/java<version>/ant/extra folder. Either open the project in the IDE and make sure CopyLibs library exists or setup the property manually. For example like this: ant -Dlibs.CopyLibs.classpath=a/path/to/org-netbeans-modules-java-j2seproject-copylibstask.jar Must set JVM to use for profiling in profiler.info.jvm Must set profiler agent JVM arguments in profiler.info.jvmargs.agent Must select some files in the IDE or set javac.includes Must select some files in the IDE or set javac.jsp.includes Must select a file in the IDE or set jsp.includes Browser not found, cannot launch the deployed application.
