J-Profiler

An award-winning all-in-one Java profiler. JProfiler's intuitive GUI helps you find performance bottlenecks, pin down memory leaks and resolve threading issues.

Even though JProfiler has a powerful feature set, it's a Java profiler that is extremely easy to use! JProfiler's user interface provides a unified view on the profiled application and puts all the information you need right at your fingertips with its intuitive hierarchy of views.

J-Profiler 3 introduces the following new features:

• The allocation hot spots view
  This new view complements the allocation tree view and makes memory leak detection much easier than before. You can mark all values and observe the differences, just like in the class monitor
• Integration of the memory views with the heap walker
  You can now select a class or allocation spot and analyze the selected objects in the heap walker with a single click
• A redesigned heap walker
  Based on user feedback we've made the heap walker more intuitive and much easier to use
• The heap walker can be told to show only recorded objects
  Now the heap walker fully integrates with the dynamic memory views and makes it much easier to focus on the objects you're interested in
• Multiple selection in heap walker views
  You can now select multiple classes or allocations spots to form new object set. For many cases this makes it much faster to find objects
• Allocation hot spots in the heap walker "Allocations" views
  This view gives you additional insight into object creation and allows you to make selection steps that were not possible before
• The reference graph
  With the reference graph you can explore references individually for each object. Searching for memory leaks is now much easier than before. The cumulated reference views are still available
• Path to GC root search in the reference view
  Previously, the path to root search was located in the instance data view of the heap walker. The new path to root search in the reference graph is much better located and more useful
• Direct display of string values in the data view of the heap walker
• Redesigned CPU hot spots view
  The bar graph instantly shows you the relative importance of hot spots. The view now has a table-like structure and can be sorted by name, percentage and invocation count
• The method graph
  In addition to invocation tree and hot spots view you can now explore call sequences as a graph
• Integration of the CPU views with the method graph
  You can create a method graph from every method in the invocation tree view and the hot spots view with one click
• Automatic deadlock detection
  The deadlock detection graph shows a graphical representation of all deadlocks in the JVM
• Support for recent versions of Java Web Start
  Java Web Start bundled with 1.4.2 can now be profiled with JProfiler
• Easy main class selection for local sessions
  Once you have set up your class path, J-Profiler can list your main classes
• Displaying a tree of call tree collection filters at runtime
  This information was previously difficult to access
• Undocking of all views to separate top-level windows
  If you ever wanted to look at two or more views side by side, this feature is for you
• Much improved export capabilities
  Now all views can be exported to HTML
• New IDE integrations for: Intelli-J IDEA 4, Netbeans 3.6, Eclipse 3.0M7 and Borland J-Builder X

A powerful cross platform Java installer that generates native installers and application launchers for Java applications. install4j excels in its ease of use and its tight integration into the target platforms.

install-4j comes in two editions, the Professional Edition and the Enterprise Edition. Features that are available in the enterprise edition only are marked as such in the the following list.

Construction of a Distribution Tree >>> install4j's GUI allows you to:

• freely define your distribution tree
  In each directory of the distribution tree you can include the contents of entire directories or single files from arbitrary directories on your disk. The definition view and the results view give you full control over the files that will be distributed by your installers
• handle platform-specific differences
  install4j offers convenient include/exclude mechanisms that let you tailor your distributions in a platform specific manner
• define file rights for Unix, Linux and Mac OS X
  For each element of the distribution tree, you can define custom access rights for installation on Unix-like platforms
• define a fine-grained uninstallation policy
  For each element of the distribution tree, you can determine whether you want the uninstaller to remove it or not
• define the overwrite policy
  For each element of the distribution tree, you can set a different overwrite police that determines what install4j will do when it has to overwrite files during an installation
• define installation components
  You can define groups of files and directories that constitute separate installation components. You can offer the user to select only certain components for installation

• Customized JRE/JDK detection
  The executable can detect appropriate Java JREs and JDKs on the target system. You can also distribute your own JRE on demand (see below). The search sequence, error handling and supported JRE/JDK versions are fully customizable
• Flexible classpath construction
  The classpath for your Java application can be fully customized to scan directories for JAR files, include specific directories and archives as well as insert environment variables. Customizable error handling allows you to interrupt the startup sequence with a specific error message instead of obscure No-Class-Def-Found exceptions later on
• GUI, console applications
  install4j lets you compile GUI applications or console applications with an associated terminal window
• Service launchers (enterprise edition only)
  Services (or daemons) are fully supported by install4j (enterprise edition only). For services, install-4j generates service executables on Windows, startup items on Mac OS X and start/stop scripts on Unix/Linux platforms
• Custom working directory
  If required you can adjust the working directory to a specific directory relative to the executable. This is especially helpful for console applications which can be invoked from arbitrary directories. This way, you don't need to define fragile environment variables like MYAPP_HOME
• VM parameters file
  For every executable, you can create a user editable VM parameters file. In this way, users can adjust VM properties like the maximum heap size
• Windows version info resource
  install4j can generate a version info resource entry in Windows executable. This version info is displayed for example in the property dialog of the Windows explorer. If you wish to obtain the "Designed for Windows" logo, this is an important requirement
• Splash screen
  For GUI applications, a splash screen gives the users of your application an optimum feedback about application startup. Textual status information about application startup and version information can be freely placed on the splash screen. From within your Java code, this status information can be easily updated with one simple call. With install4j's "auto-off" mode activated, the splash screen is hidden, as soon as your application displays a window
• Redirection of stderr and stdout
  The standard output and error streams can be redirected to customized files. This gives you access to valuable information like an exception stack trace on stderr that would otherwise be lost for a Java GUI application
• Startup failure detection
  No more flashing terminal windows and GUI applications that hang without displaying anything. install4j executables can monitor a stderr output file and display a dialog with helpful information to inform about startup failures
• Custom icon
  Install4j uses two image files to create the icon for your launcher. install4j creates Windows icons that are optimized for Windows XP and also have optimal display properties on older versions of Windows. You can also specify your own Windows icon file
• Custom process name and taskbar grouping on Windows XP
  On Microsoft Windows, install4j launches your Java application in such a way, that the install4j executable and not java.exe or javaw.exe will appear in the task manager. In Windows XP, the task bar grouping will display the name of your executable and the associated icon, instead of the non-descript terminal icon and the string "javaw"
• Application bundle on Mac OS X
  On Mac OS X, install4j executables are part of a proper application bundle. You can specify a Mac icon for your application
• Window manager integration for KDE/Gnome
  install4j generates a .desktop file that allows your users to easily place a shortcut on their desktops and desktop menus

GUI installers on Windows, Linux, Mac OS X and Unix >>> install-4j generates professional-looking installers that handle:

• Directory selection
• Displaying a license agreement and asking the user to accept it
• Selection of installation components
• Program group selection
• Creation of start menu entries for all users or a single user only
• Nested start menu entries
• File associations with generated launchers
• Selection and installation of services (enterprise edition only)
• Selection of standard tasks: creation of shortcuts on the desktop and in the quick launch bar
• Selection of custom tasks to be used by custom actions
• Displaying pre-install and post-install information files in text or HTML format
• Full rollback if the installation is canceled or fails
• Option to start launcher immediately from the installer
• Reboot option on Windows
• Creation of uninstallers
• Listing in the "Software" control panel on Windows
• Customizable images and size (enterprise edition only)

• Croatian

Full Mac OS X support >>> The GUI installer installs your application as a proper application bundle on Mac OS X. Also available is a folder-type installation, that supports application bundles for each launcher.

Unix Archives >>> As a fallback for arbitrary Unix platforms, gzipped TAR archives can be created that contain your application.

Custom Screens and Custom Actions >>> install4j GUI installers can be customized with:

• custom actions
  If your installation has to perform tasks that are not covered by install4j's standard features, you can always create a pre-installation and a post-installation custom action to add your own installation code to the installer
• custom screens (enterprise edition only)
  Especially for server installations, freely layouted custom screens in the installation wizard are a need-to-have. With custom screens, you can query your users for business domain-specific installation parameters. Even a complex screen flow can be realized with install4j's custom screens

JRE Bundling and On-Demand Download of JREs >>> With install4j, you can:

• dynamically bundle a JRE
  In this way the size of the installer is not increased by the inclusion of a JRE. On the target system, if no suitable JRE can be found, the user is prompted whether to download the JRE bundle from your site
• statically bundle a JRE
  When defining a media file in install4j, you just select a JRE for bundling and it will be distributed by the installer and used by all the generated launchers. The JRE download wizard in install4j makes it very easy to download suitable JRE bundles from ej-technologies' JRE server
