JavaCheck - Frequently Asked Questions
Q: What is JavaCheck?
A: JavaCheck 3.0 is a developer tool that ensures that applications and
applets will be compatible with Java platforms and can therefore run on
many types of devices. It does this by testing whether Java class files
used by an application or applet conform to a particular Java platform
API specification.
JavaCheck 3.0 provides support for the PersonalJavaTM Specification.
PersonalJava has been designed specifically for network-connectable consumer
devices used for communications, entertainment and mobile computing. Using
JavaCheck allows application developers to create products and services
on their desktops that will reach consumers using PersonalJava-enabled
devices. They can do this without having to purchase devices and proprietary
tools for development and testing. JavaCheck is easy to use and works
side-by-side with popular third party Java development tools.
Q: How can I get JavaCheck?
A: JavaCheck 3.0 is now available for free on Sun's website
at: http://java.sun.com/products/personaljava/javacheck.html.
JavaCheck 3.0 will also be available through many third parties as part of their
developer tool suites.
Q: What is a Platform Specification File?
A: JavaCheck uses a platform specification file as the definition of a
Java platform. A platform specification file is written in SGML-compliant text
and has an .spc file extension. JavaCheck reads a platform specification file to
represent the platform in memory so a Java program's conformance to the platform
can be assessed. Platform specification files are created or endorsed by Sun
Microsystem for use with official Java specifications. JavaCheck includes a
platform specification file for the PersonalJava platform so you can determine
your code's conformance to the PersonalJava platform. For additional
information on platform specification files, please refer to the documentation available with the product.
Q: Will other platform specification files be available for use
with JavaCheck?
A: Yes, Sun hopes to provide platform specification files (.spc)
for other Java platforms, as well as for some extensions to the Java
platform. These .spc files will be available in future versions of
JavaCheck. Information on future releases will be posted when available
on Sun's website at: http://java.sun.com/products/personaljava.
Q: Why are there two versions of JavaCheck?
A: JavaCheck 3.0 comes in two configurations: one is command-line based,
the other has a graphical user interface (GUI). Both provide the
same utility.
Q:What are the differences between JavaCheck 2.0.1 and 3.0?
A: JavaCheck 3.0 now reports dependencies for fields and methods. This
means that you will see fewer "modified" messages associated with the classes;
only the specific usage of modified fields or methods will generate these
errors.
JavaCheck 3.0 now allows users to specify classpaths. this simplifies the
process of specifying which classes should be checked. JavaCheck 3.0 also
allows you to filter
specific classes to load (e.g only load classes in package xx.yy). Finally,
JavaCheck 3.0 allows yo to specify the action to be taken when duplicate classes
are encountered.
Q: Can I use my spec files from JavaCheck 2.0.1 with JavaCheck 3.0?
A: No. The spec file format has changed. JavaCheck 2.0.1 will not be
able to read the PersonalJava 1.1 specfile (pJava_1.1.0.spc). JavaCheck 3.0
will not properly read the PersonalJava 1.0.1 specfile (pJava1.0.spc).
Q: Where can I send comments on JavaCheck 3.0?
A: We always appreciate your feedback on our products. Please email

Q: What is the difference between JavaCheck and JavaPureCheckTM?
A: JavaCheck is a conformance checking tool that reports whether a Java
application or applet conforms to a given specification of a Java platform.
JavaPureCheck tests that an application or applet is written using 100%
Pure Java.
