AspectJ programs can be run in the debugger in the same way as Java programs. The tools enable the user to step into, through and out of advice. The AspectJ development tools also provide the facility to set breakpoints in aspects.

No. The AspectJ tools download is completely self-contained and does not require that you work in Eclipse. For information on IDE support, see Q: How well does AspectJ integrate with existing Java development tools?.

AspectJ 1.1 is built on Eclipse/JDT's Java compiler but is distributed standalone and can run standalone. With the AspectJ distribution, you can compile and run AspectJ programs and use the AspectJ structure browser. AJDT is an eclipse project to integrate AspectJ into Eclipse/JDT so you can use Eclipse to develop AspectJ programs. AJDT aims to support the full Eclipse experience - searching, compiler-error tasks, etc.

Use the Tracer. In tkeclipse, choose "Tracer" from the Tools menu. See the chapter on "Debugging" in the User Manual; and the worked example in chapter 5 of the ECLiPSe Tutorial.

You need to specify to the compiler the files that contain your aspects and the files that contain the types affected by your aspects. See Q: How do I know which aspects affect a class when looking at that class's source code?. The AspectJ compiler will not search the source path for types that may be affected (unlike Javac and Jikes). In AspectJ 1.0, ajc requires all code to be in source form; in AspectJ 1.1, Java and AspectJ code may be in either source or binary form.

A : First, remember to use the -g switch when you compile and link. This puts debugging information into your executable. When linking, don't use the -s switch, and give the name of the output file without the .exe extension , so that gcc will leave both the COFF output and the DOS executable after the link stage. Here are a few examples of compilation and link command lines when you intend to debug a program: gcc -Wall -c -g -O myfile.c gcc -Wall -O2 -g -o myprog mymain.c mysub1.c mysub2.

AspectJ(tm) is a simple and practical extension to the Java(tm) programming language that adds to Java aspect-oriented programming (AOP) capabilities. AOP allows developers to reap the benefits of modularity for concerns that cut across the natural units of modularity. In object-oriented programs like Java, the natural unit of modularity is the class. In AspectJ, aspects modularize concerns that affect more than one class.

Using aspects reduces, as a side effect, the number of source lines in a program. However, the major benefit of using aspects comes from improving the modularity of a program, not because the program is smaller. Aspects gather into a module concerns that would otherwise be scattered across or duplicated in multiple classes. The issue of performance overhead is an important one.

The SIMPOL IDE has extensive support for debugging programs. It is actually much easier to debug a program in SIMPOL than in SBL. The IDE has support for real breakpoints (including breaking only on a certain condition), the ability to examine the values of variables and objects, etc. It also includes a profiler to help you identify where your code is spending most of its time. See the IDE Tutorial and the IDE Handbook for more information.

In any cases where your program is longer than a few hundred lines, you will need to be able to run it through a debugger. Pascal programs compiled with GPC can be debugged via the GNU debugger dbg which we have installed on our Sun Fire system. However, the debugger is designed for C-code, and is rather kloncky if used with Pascal. But it is the only debugger available that works with GPC.

AspectJ 1.1 through 1.5.1 source code and documentation is available under the Common Public License 1.0. The AspectJ 1.0 tools are open-source software available under the Mozilla Public License 1.1. That documentation is available under a separate license that precludes for-profit or commercial redistribution. Most users only want to use AspectJ to build programs they distribute. There are no restrictions here.

AspectJ is based on over ten years of research at Xerox Palo Alto Research Center as funded by Xerox, a U.S. Government grant (NISTATP), and a DARPA contract. It has evolved through open-source releases to a strong user community and now operates as an open source project at http://eclipse.org/aspectj The AspectJ team works closely with the community to ensure AspectJ continues to evolve as an effective aspect-oriented programming language and tool set. The latest release is 1.

Yes, it is possible to debug Java programs that use Oracle Thin JDBC Driver with Symantec Visual Cafe? Java development tool. However, it is not possible to debug JDBC OCI programs with Visual Cafe?.

Yes, it is possible to debug Java programs that use Oracle Thin JDBC Driver with Microsoft Visual J++ Java development tool. Further, it is also possible to debug JDBC OCI programs in Visual J++ but the driver has been built for the Javasoft Java VM. It is therefore necessary to modify the Visual J++ environment to run using the Javasoft Java VM instead of the Microsoft VM. For more information, see the following web site: http://www.javaworld.com/javaworld/javatips/jw-javatip25.html

Developing: Creating SQLJ code in JDeveloper is no different than creating Java code. SQLJ files (.sqlj) can be included in your projects as well as Java files (.java). Compiling: When you compile a SQLJ source file (identified by the .sqlj file extension), the Oracle SQLJ translator and Oracle profile customizer are automatically invoked. Prior to compiling, you can use JDeveloper to set some of the SQLJ command-line translation options.

No, not for full (high level source language) debugging. The Microsoft compilers generate a different type of debugging symbol information, which gdb does not understand. However, the low-level (assembly-type) symbols generated by Microsoft compilers are coff, which gdb DOES understand. Therefore you should at least be able to see all of your global symbols; you just won't have any information about data types, line numbers, local variables etc.

The code for these concerns tends to be spread out across the system. Because these concerns won't stay inside of any one module boundary, we say that they crosscut the system's modularity. AspectJ adds constructs to Java that enable the modular implementation of crosscutting concerns. This ability is particularly valuable because crosscutting concerns tend to be both complex and poorly localized, making them hard to deal with.

From AspectJ's web page , download the AspectJ distribution. The jar file is installed by executing java -jar jar file name Do not try to extract the jar file contents and then attempt to execute java org.aspectj.tools.Main. (A NoClassDefFoundError exception will be thrown.) The AspectJ distribution is not designed to be installed this way. Use the java -jar form shown above. To uninstall, remove the files the installer wrote in your file system.

Many users adopt AspectJ in stages, first using it to understand and validate their systems (relying on it only in development) and then using it to implement crosscutting concerns in production systems. AspectJ has been designed to make each step discrete and beneficial. In the development process Use AspectJ to trace or log interesting information. You can do this by adding simple AspectJ code that performs logging or tracing.

The AspectJ compiler or weaver is required at some point, but many people can use AspectJ without changing their build or deployment process significantly. For aspects that are not required to compile, you can use the AspectJ binary weaver, run at build-time or class-load-time. You can write aspects using the original code style (which must be compiled with the AspectJ compiler) or using the annotation style new in AspectJ 5 (which may be compiled with Javac or the AspectJ compiler).

Just include the aspectjrt.jar as a required archive. For example, here is the HTML code for an HTML editor applet that contains some debugging aspects: <APPLET CODE='com.company.swing.applets.EditorApplet' WIDTH='700' HEIGHT='525'> <PARAM NAME="CODE" VALUE="com.company.swing.applets.EditorApplet" > <PARAM NAME="ARCHIVE" VALUE ="../company-applets.jar,../aspectjrt.jar,../xmlrpc-applet.jar" > <PARAM NAME="type" VALUE="application/x-java-applet;version=1.

You can reach other AspectJ users by using the aspectj-users mailing list. You can subscribe to the list or view the list archives from the AspectJ home page http://eclipse.org/aspectj .

Below is a table describing the goals for the major releases. For information about specific features, search the bug database for RFE's ("requests for enhancement") by selecting severity of "enhancement". Like many open-source projects, we don't make or promise schedules, but we do follow a pattern of issuing preview releases which can give observers an idea of when a particular release might be available.
