22 | <h3>Description</h3>
|
---|
23 | <p>Class to precompile JSP's using weblogic's jsp compiler (weblogic.jspc)</p>
|
---|
24 | Tested only on Weblogic 4.5.1 - NT4.0 and Solaris 5.7,5.8<br>
|
---|
25 | <h3>Parameters</h3>
|
---|
26 | <table border="1" cellPadding="2" cellSpacing="0">
|
---|
27 | <tbody>
|
---|
28 | <tr>
|

|
---|
34 | <td>src</td>
|
---|
35 | <td>root of source tree for JSP, ie, the document root for your weblogic server</td>
|
---|
36 | <td>Yes</td>

|
---|
39 | <td>
|
---|
40 | dest</td>
|
---|
41 | <td> root of destination directory, what you have set as WorkingDir in the weblogic properties</td>
|
---|
42 | <td>Yes</td>

45 | <td>
|
---|
46 | package</td>
|
---|
47 | <td> start package name under which your JSP's would be compiled</td>
|
---|
48 | <td>Yes</td>
|
---|
49 | </tr>

50 | <tr>
|

51 | <td>
|

52 | classpath</td>

53 | <td>Class path to use when compiling jsp's</td>
|

|
---|
58 | <p>
|
---|
59 | <br>
|
---|
60 |
|
---|
61 | A classpath should be set which contains the weblogic classes as well as all application classes<br>
|
---|
62 | referenced by the JSP. The system classpath is also appended when the jspc is called, so you may<br>
|
---|
63 | choose to put everything in the classpath while calling Ant. However, since presumably the JSP's will reference<br>
|
---|
64 | classes being build by Ant, it would be better to explicitly add the classpath in the task<br>
|
---|
65 | <br>
|
---|
66 | The task checks timestamps on the JSP's and the generated classes, and compiles<br>
|
---|
67 | only those files that have changed.<br>
|
---|
68 | <br>
|
---|
69 | It follows the weblogic naming convention of putting classes in<br>
|
---|
70 | <b> _dirName/_fileName.class for dirname/fileName.jsp </b><br>

---|

90 | <h3>Limitations</h3>
|
---|
91 | <ul>
|
---|
92 | <li>This works only on weblogic 4.5.1</li>
|
---|
93 | <li>It compiles the files thru the Classic compiler only.</li>
|
---|
94 | <li>Since it is my experience that weblogic jspc throws out of memory error on being given too
|
---|
95 | many files at one go, it is called multiple times with one jsp file each.</li>
|
---|
96 | </ul>
