| </PRE> | |
| <P> | |
| Utility class to report simple information about the environment. | |
| Simplistic reporting about certain classes found in your JVM may | |
| help answer some FAQs for simple problems. | |
| <p>Usage-command line: | |
| <code> | |
| java org.apache.xalan.xslt.EnvironmentCheck [-out outFile] | |
| </code></p> | |
| <p>Usage-from program: | |
| <code> | |
| boolean environmentOK = | |
| (new EnvironmentCheck()).checkEnvironment(yourPrintWriter); | |
| </code></p> | |
| <p>Usage-from stylesheet: | |
| <code><pre> | |
| <?xml version="1.0"?> | |
| <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0" | |
| xmlns:xalan="http://xml.apache.org/xalan" | |
| exclude-result-prefixes="xalan"> | |
| <xsl:output indent="yes"/> | |
| <xsl:template match="/"> | |
| <xsl:copy-of select="xalan:checkEnvironment()"/> | |
| </xsl:template> | |
| </xsl:stylesheet> | |
| </pre></code></p> | |
| <p>Xalan users reporting problems are encouraged to use this class | |
| to see if there are potential problems with their actual | |
| Java environment <b>before</b> reporting a bug. Note that you | |
| should both check from the JVM/JRE's command line as well as | |
| temporarily calling checkEnvironment() directly from your code, | |
| since the classpath may differ (especially for servlets, etc).</p> | |
| <p>Also see http://xml.apache.org/xalan-j/faq.html</p> | |
| <p>Note: This class is pretty simplistic: | |
| results are not necessarily definitive nor will it find all | |
| problems related to environment setup. Also, you should avoid | |
| calling this in deployed production code, both because it is | |
| quite slow and because it forces classes to get loaded.</p> | |
| <p>Note: This class explicitly has very limited compile-time | |
| dependencies to enable easy compilation and usage even when | |
| Xalan, DOM/SAX/JAXP, etc. are not present.</p> | |
| <p>Note: for an improved version of this utility, please see | |
| the xml-commons' project Which utility which does the same kind | |
| of thing but in a much simpler manner.</p> | |
