Launches a Java application. The java command starts a Java application. It does this by starting a Java runtime environment, loading a specified class, and calling that classs main method. The method must be declared public and static, it must not return any value, and it must accept a String array as a parameter. In todays post I will discuss on steps you should doneed for Oracle Apps R12 installation. Most of these steps are written w. Installation on Linux but I. Launches a Java application. Synopsis. java options class arguments java options jar file. Commandline options. See Options. Disassembles class files. SYNOPSIS javap options classes DESCRIPTION. The javap command disassembles one or more class files. Its output depends on the options used. InputOutput options filename Short for include filename. Recursively reads configuration options from the given file filename.

The method declaration has the following form By default, the first argument without an option is the name of the class to be called. A fully qualified class name should be used. Vu Solo2 Vti. If the jar option is specified, then the first non option argument is the name of a JAR file containing class and resource files for the application, with the startup class indicated by the Main Class manifest header. The Java runtime searches for the startup class, and other classes used, in three sets of locations the bootstrap class path, the installed extensions, and the user class path. Non option arguments after the class name or JAR file name are passed to the main function. The launcher has a set of standard options that are supported in the current runtime environment. In addition, the current implementations of the virtual machines support a set of nonstandard options that are subject to change in future releases. See Nonstandard Options. Selects the Java Hot.

JDK currently ignores this option and instead uses the Java Hotspot Server VM. For default Java VM selection, see the Server Class Machine Detection page athttp docs. Selects the Java Hot. Spot Server VM. On a 6. JDK, only the Java Hotspot Server VM is supported so the server option is implicit. For default a Java VM selection, see the Server Class Machine Detection page athttp docs. Loads native agent library libname, for example. See JVMTI Agent Command Line Options athttp docs. Loads a native agent library by full pathname. Specifies a list of directories, JAR files, and ZIP archives to search for class files. Separate class path entries with colons. Specifying classpath or cp overrides any setting of the CLASSPATH environment variable. If classpath and cp are not used and CLASSPATH is not set, then the user class path consists of the current directory. As a special convenience, a class path element that contains a base name of is considered equivalent to specifying a list of all the files in the directory with the extension. JAR. A Java program cannot tell the difference between the two invocations. For example, if directory mydir contains a. JAR, then the class path element mydiris expanded to a A. JAR, except that the order of jar files is unspecified. All jar files in the specified directory, even hidden ones, are included in the list. A class path entry consisting simply of expands to a list of all the jar files in the current directory. The CLASSPATH environment variable, where defined, will be similarly expanded. Any class path wildcard expansion occurs before the Java VM is started. No Java program will ever see wild cards that are not expanded except by querying the environment. For example, by calling System. CLASSPATH. Dpropertyvalue. Sets a system property value. Run the application in a 3. Rt.Jar File' title='Rt.Jar File' />If a 3.

This is subject to change in a future release. Disable assertions. This is the default. With no arguments, disableassertions or da disables assertions. With one argument ending in., the switch disables assertions in the specified package and any subpackages. If the argument is., then the switch disables assertions in the unnamed package in the current working directory. With one argument not ending in., the switch disables assertions in the specified class. To run a program with assertions enabled in package com. Brickbat, the following command could be used. Brickbat lt Main Class. The disableassertions and da switches apply to all class loaders and to system classes which do not have a class loader. There is one exception to this rule in their no argument form, the switches do not apply to system. This makes it easy to turn on asserts in all classes except for system classes. The disablesystemassertions option provides a separate swith to enable assertions in all system classes. Enable assertions. Assertions are disabled by default. With no arguments, enableassertions or ea enables assertions. With one argument ending in., the switch enables assertions in the specified package and any subpackages. If the argument is., then the switch enables assertions in the unnamed package in the current working directory. With one argument not ending in., the switch enables assertions in the specified class. If a single command contains multiple instances of these switches, then they are processed in order before loading any classes. So, for example, to run a program with assertions enabled only in package com. Main Class. The enableassertions and ea switches apply to all class loaders and to system classes which do not have a class loader. There is one exception to this rule in their no argument form, the switches do not apply to system. This makes it easy to turn on asserts in all classes except for system classes. The enablesystemassertions option provides a separate switch to enable assertions in all system classes. Enable assertions in all system classes sets the default assertion status for system classes to true. Disables assertions in all system classes. Displays usage information and exit. Executes a program encapsulated in a JAR file. The first argument is the name of a JAR file instead of a startup class name. For this option to work, the manifest of the JAR file must contain a line in the form Main Class classname. Here, classname identifies the class with the public static void mainString args method that serves as your applications starting point. When you use this option, the JAR file is the source of all user classes, and other user class path settings are ignored. JAR files that can be run with the java jar option can have their execute permissions set so they can be run without using java jar. See the JAR File Overview athttp docs.
