<h1>wljspc</h1>
<h3>Description</h3>
<p>Class to precompile JSP's using weblogic's jsp compiler (weblogic.jspc)</p>
Tested only on Weblogic 4.5.1 - NT4.0 and Solaris 5.7,5.8<br>
<h3>Parameters</h3>

    <tr>
      <td>src</td>
      <td>oot 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 WorkingDir in the weblogic properties</td>
      <td>Yes</td>

      <td>
package</td>
      <td> start package name under which your JSP's would be compiled</td>
      <td>Yes</td>

classpath</td>
      <td>Class path to use when compiling jsp's</td>
      <td>Yes</td>
    </tr>
  </tbody>
</table>
<p>
<br>

A classpath should be set which contains the weblogic classes as well as all application classes<br>
referenced by the JSP. The system classpath is also appended when the jspc is called, so you may<br>
choose to put everything in the classpath while calling Ant. However, since presumably the JSP's will reference<br>
classes being build by Ant, it would be better to explicitly add the classpath in the task<br>
<br>
The task checks timestamps on the JSP's and the generated classes, and compiles<br>
only those files that have changed.<br>
<br>
It follows the weblogic naming convention of putting classes in<br>
<b> _dirName/_fileName.class for dirname/fileName.jsp   </b><br>
<br>
</p>
<h3><br>
Example<br>
</h3>
<p>
&lt;target name="jspcompile" depends="compile"><br>
&lt;wljspc src="c:\\weblogic\\myserver\\public_html" dest="c:\\weblogic\\myserver\\serverclasses" package="myapp.jsp" ><br>
&lt;classpath&gt;<br>
&lt;pathelement location="${weblogic.classpath}" /><br>
&lt;pathelement path="${compile.dest}" /><br>
&lt;/classpath&gt;<br>
<br>
&lt;/wljspc&gt;<br>
&lt;/target>
</p>
<h3>
<br>
Limitations
</h3>
<p>
This works only on weblogic 4.5.1
<br>
It compiles the files thru the Classic compiler only.<br>
 Since it is my experience that weblogic jspc throws out of memory error on being given too<br>
many files at one go, it is called multiple times with one jsp file each.
