@node ax_java_check_class
@unnumberedsec ax_java_check_class
@majorheading Synopsis
@smallexample
AX_JAVA_CHECK_CLASS(<class>,<action-if-found>,<action-if-not-found>)
@end smallexample
@majorheading Description
Test if a Java class is available. Based on AX_PROG_JAVAC_WORKS. This
version uses a cache variable which is both compiler, options and
classpath dependent (so if you switch from javac to gcj it correctly
notices and redoes the test).
The macro tries to compile a minimal program importing <class>. Some
newer compilers moan about the failure to use this but fail or produce a
class file anyway. All moaing is sunk to /dev/null since I only wanted
to know if the class could be imported. This is a recommended followup
to AX_CHECK_JAVA_PLUGIN with classpath appropriately adjusted.
