1 1  [[Xalan-J>>http://xml.apache.org/xalan-j/||rel="__blank" title="Xalan-J Home Page"]] is a Java based XSLT engine by the Apache Project.

17 17  * JDBC connectivity
18 -* Java properties
19 -* CheckEnv()
20 20  
29 +== Java properties disclosure ==
30 +
31 +The xsl:system-property() standard function can be called with non standard arguments, mapped to Java properties. In this example, the name of the Java properties is stored in a separate XML file ([[properties.xml>>attach:properties.xml]]). The XSLT code will, for each property, display its name and its value.

35 +
36 +
37 +== Java environment disclosure ==
38 +
39 +The checkEnvironment() extension function (documented [[here>>http://xml.apache.org/xalan-j/faq.html#faq-N10064||rel="__blank"]]) will display some information about the execution context (packages, paths, versions, ...).

46 +The attached code will display the current date using a newly created "java.util.Date" object. This should be enough to demonstrate Java code execution.
