Tools Home Page java: Java Application Launcher ● Synopsis ● Deviations from Standard Java Options ● Nonstandard Java Options ● Deviations from Nonstandard Java Options ● HP Extensions to Standard Java Options ● See Also The java tool launches a Java application by starting a Java run-time environment, loading a specified class, and invoking that class' main method. For a complete description of the tool and its use, see the Sun Microsystems documentation for java.
-d64 Selects whether the program is to be run in a 32-bit or 64-bit environment. Note: These options are not valid with NonStop Server for Java 4, which uses only the 32-bit environment to run Java programs. Nonstandard Java Options The following nonstandard options are shown for your convenience; their implementations are a typical Java implementation. -Xssn Sets the thread stack size. Every thread spawned while a Java program runs has its own stack.
-XX:+UseConcMarkSweepGC Specifies using the concurrent mark-sweep garbage collector. This option is disabled. If you specify this option, the Java VM exits with the error: -XX:+UseConcMarkSweepGC option is not supported on this platform. -Xconcgc Enables a concurrent mark-sweep garbage collector. This option is disabled. If you specify this option, the Java VM exits with the error: -Xconcgc option is not supported on this platform. -Xincgc Specifies using the incremental low-pause garbage collector.

Tools Home Page jdb: Java Debugger The jdb tool helps you find and fix errors in Java programs. For a complete description of the tool and its use, see the Sun Microsystems documentation for jdb.
Description The Java Debugger, jdb, is a simple command-line debugger for Java classes. It is an example of the use of the Java Platform Debugger Architecture that provides inspection and debugging of a local or remote Java virtual machine (VM). Starting a jdb Session There are many ways to start a jdb session. The most frequent way is to have jdb launch a new Java VM with the main class of application to be debugged. You do this by substituting the command jdb for the command java in the command line.
You can then attach jdb to the Java VM with the following command: jdb -attach 8000 Note: MyClass is not specified in the jdb command line in this case because jdb connects to an existing Java VM instead of launching a new one. There are many other ways to connect the debugger to a Java VM, and all of them are supported by jdb, as specified in Connecting for Remote Debugging. Basic jdb Commands The following is a list of the basic jdb commands.
❍ print myObj.myMethod() (if myMethod() returns a non-null) ❍ print new java.lang.String("Hello").length() dump For primitive values, this command is identical to print. For objects, it prints the current value of each field defined in the object. Static and instance fields are included. The dump command supports the same set of expressions as the print command. threads List the threads that are currently running.
● stop in java.lang.String.length (sets a breakpoint at the beginning of the method java.lang.String.length) ● stop in MyClass.init (init identifies the MyClass constructor) ● stop in MyClass.clinit (clinit identifies the static initialization code for MyClass) If a method is overloaded, you must also specify its argument types so that the proper method can be selected for a breakpoint. For example, MyClass.myMethod(int,java.lang.String), or MyClass.myMethod().
Command-Line Options When you use jdb in place of the Java application launcher on the command line, jdb accepts many of the same options as the java command, including -D, -classpath, and -Xoption. The following additional options are accepted by jdb: -help Displays a help message. -sourcepath directory1 [:directory2]... Uses the given path in searching for source files in the specified path. If this option is not specified, the default path of "." is used.
Deviations from Standard Java -tclient Runs the application in the Java HotSpot client VM. Note: The -tclient option is not valid with NonStop Server for Java 4. -tserv Runs the application in the Java HotSpot server VM. Note: -tserv is the default option for NonStop Server for Java 4; therefore, specifying -tserv is optional. Options Forwarded to the Process Being Debugged -v -verbose[:class|gc|nji] Turns on verbose mode. -D name=value Sets a system property. -classpath directory1 [:directory2]...
-Xrunjdwp:transport=dt_socket,\ address=hostname:portnum,server=y ClassName Note: If address option is not given, the server will start on any available port on the local host and print portnum. This portnum should be used by the jdb to attach. iii. The target JVM attaches to previously running debugger. -listen jdb -listen hostname:portnum To attach a target Java VM, use the following command : java -Xnoagent -Xdebug -Djava.
