This document helps in troubleshooting problems that might occur with applications that use the desktop technologies in the release of Java Platform, Standard Edition Development Kit 6 (JDK 6 release or Java SE 6 release).
Most of the information in this guide also applies to the Java SE 5 release (also known as Java 2 SE 1.5 or 5.0). Information that applies only to Java SE 6 is indicated accordingly.
For help in troubleshooting possible problems between the application and the Java HotSpot virtual machine, see the Troubleshooting Guide for Java SE 6 with HotSpot VM or the Java 2 SE 5.0 Troubleshooting and Diagnostic Guide.
The target audience for this document comprises developers who are working with the desktop technologies in Java SE 5 or 6, as well as support or administration personnel who maintain applications that are deployed with Java SE 5 or 6.
This document is intended for readers with a detailed understanding of the desktop technologies, a high-level understanding of the components of the Java Virtual Machine, as well as some understanding of concepts such as garbage collection, threads, native libraries, and so on. In addition, it is assumed that the reader is reasonably proficient on the operating system where the Java SE application is installed.
The first chapter of this guide introduces the desktop technologies, presents some general troubleshooting information and guidelines, and introduces some troubleshooting tools.
Further chapters suggest procedures to try when you encounter problems with some of the desktop technologies, namely, AWT, Java 2D, Swing, Internationalization, Java Sound, and Java Plug-in. More desktop technologies will be gradually added to this guide.
The last chapter provides suggestions on what to try before submitting a bug report, guidance on how to submit a report, and suggestions on what data to collect for the report.
Finally, there is an appendix for each of the following reference areas: Java 2D properties, and details about the format of the fatal error report.

The following additional online troubleshooting resources are available:
Sun provides a wide range of support offerings, from developer technical support for software developers using Sun development products or technologies, to support for production systems in enterprise environments. Two commercial support options are summarized here: developer technical support and Java mulitplatform support.
Developer technical support is aimed at developers who are using Sun development products or technologies, and who are working at the source-code level of their own applications.
This support offering includes response to technical questions, diagnostic and troubleshooting help, suggestions for best practices, bug escalation, and more.
Details on these support offerings are provided at the Services site for Sun Developer Network. This site steers you to information about developer support from Sun, for example:
The Java multiplatform support offering is designed to provide production support for shipping releases of Java technology-based applications using Sun's Java runtime environment (JRE) and distributed to end users in heterogeneous environments. This support offering helps to optimize application performance and to reduce time spent keeping applications up and running.
The highest level of this support offering can include accelerated access to an engineer and emergency software fixes. Details on this support offering are available at the SunSpectrum Java MultiPlatform site.
Community support can often be obtained using the Java Technology Forums. The forums provide a way to share information and locate solutions to problems. The forums are located at http://forums.java.sun.com.
