0036: * Utility class to report simple information about the environment.
0037: * Simplistic reporting about certain classes found in your JVM may
0038: * help answer some FAQs for simple problems.
0039: *
0040: * <p>Usage-command line:
0041: * <code>
0042: * java org.apache.xalan.xslt.EnvironmentCheck [-out outFile]
0043: * </code></p>
0044: *
0045: * <p>Usage-from program:
0046: * <code>
0047: * boolean environmentOK =
0048: * (new EnvironmentCheck()).checkEnvironment(yourPrintWriter);
0049: * </code></p>
0050: *
0051: * <p>Usage-from stylesheet:
0052: * <code><pre>
0053: * <?xml version="1.0"?>
0054: * <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"
0055: * xmlns:xalan="http://xml.apache.org/xalan"

0061: * </xsl:stylesheet>
0062: * </pre></code></p>
0063: *
0064: * <p>Xalan users reporting problems are encouraged to use this class
0065: * to see if there are potential problems with their actual
0066: * Java environment <b>before</b> reporting a bug. Note that you
0067: * should both check from the JVM/JRE's command line as well as
0068: * temporarily calling checkEnvironment() directly from your code,
0069: * since the classpath may differ (especially for servlets, etc).</p>
0070: *
0071: * <p>Also see http://xml.apache.org/xalan-j/faq.html</p>
0072: *
0073: * <p>Note: This class is pretty simplistic:
0074: * results are not necessarily definitive nor will it find all
0075: * problems related to environment setup. Also, you should avoid
0076: * calling this in deployed production code, both because it is
0077: * quite slow and because it forces classes to get loaded.</p>
0078: *
0079: * <p>Note: This class explicitly has very limited compile-time
0080: * dependencies to enable easy compilation and usage even when
0081: * Xalan, DOM/SAX/JAXP, etc. are not present.</p>
0082: *
0083: * <p>Note: for an improved version of this utility, please see
0084: * the xml-commons' project Which utility which does the same kind
0085: * of thing but in a much simpler manner.</p>
