| <h1>wljspc</h1> |
| <h3>Description</h3> |
| <p>Class to precompile JSP's using WebLogic JSP compiler (<code>weblogic.jspc</code>)</p> |
| <p>Tested only on WebLogic 4.5.1—NT 4.0 and Solaris 7 & 8</p> |
| <h3>Parameters</h3> |
| <table class="attr"> |
| <thead> |
| <tr> |
| <th scope="col">Attribute</th> |
| <th scope="col">Values</th> |
| <th scope="col">Required</th> |
| </tr> |
| </thead> |
| <tbody> |
| <tr> |
| <td>src</td> |
| <td>root of source tree for JSP, ie, the document root for your WebLogic server</td> |
| <td>Yes</td> |
| </tr> |
| <tr> |
| <td>dest</td> |
| <td>root of destination directory, what you have set as <code>WorkingDir</code> in the |
| WebLogic properties</td> |
| <td>Yes</td> |
| </tr> |
| <tr> |
| <td>package</td> |
| <td>start package name under which your JSPs would be compiled</td> |
| <td>Yes</td> |
| </tr> |
| <tr> |
| <td>classpath</td> |
| <td>Class path to use when compiling JSPs</td> |
| <td>Yes</td> |
| </tr> |
| </tbody> |
| </table> |
| <p>A classpath should be set which contains the WebLogic classes as well as all application classes |
| referenced by JSP. The system classpath is also appended when the <code>jspc</code> is called, so |
| you may choose to put everything in the classpath while calling Apache Ant. However, since |
| presumably JSPs will reference classes being build by Ant, it would be better to explicitly add the |
| classpath in the task.</p> |
| <p>The task checks timestamps on the JSP's and the generated classes, and compiles only those files |
| that have changed.</p> |
| <p>It follows the WebLogic naming convention of putting classes in <samp>_dirName/_fileName.class |
| for dirname/fileName.jsp</samp></p> |
| <h3>Example</h3> |
| <pre> |
| <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> |
| |
| <h3>Limitations</h3> |
| <ul> |
| <li>This works only on WebLogic 4.5.1</li> |
| <li>It compiles the files through the Classic compiler only.</li> |
| <li>Since it is my experience that <code>weblogic.jspc</code> throws out of memory error on being |
| given too many files at one go, it is called multiple times with one JSP file each.</li> |
| </ul> |
