- /**
- * Precompiles JSP's using WebLogic's JSP compiler (weblogic.jspc).
- *
- *
- * Tested only on Weblogic 4.5.1 - NT4.0 and Solaris 5.7
- *
- * required attributes
- * src : root of source tree for JSP, ie, the document root for your weblogic server
- * dest : root of destination directory, what you have set as
- * WorkingDir in the weblogic properties
- * package : start package name under which your JSP's would be compiled
- *
- * other attributes
- * classpath
- *
- * A classpath should be set which contains the weblogic classes as well as all
- * application classes referenced by the JSP. The system classpath is also
- * appended when the jspc is called, so you may choose to put everything in
- * the classpath while calling Ant. However, since presumably the JSP's will
- * reference classes being build by Ant, it would be better to explicitly add
- * the classpath in the task
- *
- * The task checks timestamps on the JSP's and the generated classes, and compiles
- * only those files that have changed.
- *
- * It follows the weblogic naming convention of putting classes in
- * <b> _dirName/_fileName.class for dirname/fileName.jsp </b>
- *
- * Limitation: It compiles the files thru the Classic compiler only.
- * Limitation: Since it is my experience that weblogic jspc throws out of
- * memory error on being given too many files at one go, it is
- * called multiple times with one jsp file each.
- *
- * <pre>
- * example
- * <target name="jspcompile" depends="compile">
- * <wljspc src="c:\\weblogic\\myserver\\public_html"
- * dest="c:\\weblogic\\myserver\\serverclasses" package="myapp.jsp">
- * <classpath>
- * <pathelement location="${weblogic.classpath}" />
- * <pathelement path="${compile.dest}" />
- * </classpath>
- *
- * </wljspc>
- * </target>
- * </pre>
