Overview Key Features Screenshots Tutorials/Demos IDE Integration Docs AppPerfect Java Code Test AppPerfect Java Code Test is a static Java code analysis software designed to perform the following two key tasks: Automate Java code review and Enforce Good Java Coding Practices. AppPerfect Code Test analysis your Java and Java Server Pages (JSP) source code and applies over 750 Java coding rules to apply the collective knowledge of leading experts in the Java programming field to your code. Locating and fixing performance problems during source code development time is arguably the cheapest way to resolve problems. As your project goes past the development phase, in to testing and deployment, the cost of fixing problems grows exponentially. By conducting source code analysis and successfully identifying and correcting all such issues, software developers can eliminate the risk and potential costs early in the software development cycle. Apply 750 Java coding rules: Test your Java code against over 750 built-in rules, representing the collective knowledge of numerous experts in the field. These rules are categorized into various functional areas such as security, optimization, portability, i18n, possible errors, coding standards, etc. Auto fix over 180 types of violations: Once errors are detected, AppPerfect can automatically fix over 180 types of violations. You simply review and approve the changes. Detailed Metrics Information: AppPerfect will thoroughly analyze your Java code and provides detailed information about various metrics for the source code like number of code lines, comments lines, complexities of methods, number of methods, etc. This information is vital for Java code compliance Informative and user friendly reports: AppPerfect Java Code Analyzer provides reports that help you pin point problems in your code. These reports are available through the UI and can be exported into various formats like HTML, PDF, CSV, XLS, XML etc. Scheduling & Notification: You can automate your Java code review by scheduling your code analysis tests using the Test Manager product. You can also use the built in Notifications manager module of the Test Manager product to send an email, SMS or file notification when a test is complete. IDE Integration: AppPerfect Java Code Test supports IDE integration with most commonly used IDEs. This enhances ease-of-use and productivity. Currently supported IDEs are Eclipse, NetBeans, IntelliJ, JBuilder and JDeveloper. ANT Integration and Command line execution: Test execution can be integrated into ANT build scripts to automate Java code testing. A more generic command line

Node to view thread profiling summary. Click on Thread Profiling-> Threads node in the tree on the left. A chart displaying the state of each thread started by the target application are displayed. Note that the left edge of each bar represents the start time of the application and right edge represents the current time. During this time, the state of any of the threads may have changed. This view helps graphically identify any threads that may be blocked or waiting. Click on Status tab in the Threads view. This table displays the current status and other information about each thread. If there are too many threads, you may sort the data based on any of the columns. Click on Thread Profiling-> Monitors node in the tree on the left. A monitor is a resource (an object, system resource, etc.) which two are more threads attempt to access concurrently. Concurrent access forces all the other threads except for one accessing the monitor to wait for the monitor. This view details all such monitors and details about them. Higher the monitor contention rate, the more likely your application is not properly multithreaded and will perform poorly. Click on Thread Profiling-> Deadlocks node in the tree on the left. Click on the Detect Dead Lock button on the r.h.s. If a deadlock condition was detected (a cyclical waiting of two or more threads), it would be graphically displayed in this view. Exercise 6: Detecting Memory Leaks Detecting memory leaks is a key function of the AppPerfect Java Profiler. A memory leak is defined as an application error in which objects that were thought to have been disposed are not disposed because of a reference to that object from somewhere in the application. Over time, if such objects continue being created without getting garbage collected, they will grow to consume all available memory, leading to application shutdown. Memory leak detection requires significant knowledge of the underlying application being profiled. Start a browser and connect to the PetStore application ( Click on "enter the store". Select "Memory Leaks" node in the l.h.s. tree and click on "Start Scenario..." button. AppPerfect Java Profiler will force a Garbage Collection and register all live objects present in memory after the GC. A message asking to execute the test scenario in your application will be displayed. Click on the OK button. Now go through the action of ordering "Adult Amazon Parrot". Check out, and then log out. Close the browser. Click on "Stop Scenario" button. A message will be displayed informing that Memory leak detection scenario has been completed and do you want to take a heap snapshot to view the allocations and reference details of the reported leak objects. Click on the Yes button. Now the focus will move to Heap Browser node. A dialog will be displayed asking whether you want to view details for any specific class. For the sake of this exercise will not specify any particular class. Click on the OK button to
