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

42 | <p>
|
---|
43 | <br>
|
---|
44 |
|
---|
45 | A classpath should be set which contains the weblogic classes as well as all application classes<br>
|
---|
46 | referenced by the JSP. The system classpath is also appended when the jspc is called, so you may<br>
|
---|
47 | choose to put everything in the classpath while calling Ant. However, since presumably the JSP's will reference<br>
|
---|
48 | classes being build by Ant, it would be better to explicitly add the classpath in the task<br>
|
---|
49 | <br>
|
---|
50 | The task checks timestamps on the JSP's and the generated classes, and compiles<br>
|
---|
51 | only those files that have changed.<br>
|
---|
52 | <br>
|
---|
53 | It follows the weblogic naming convention of putting classes in<br>
|
---|
54 | <b> _dirName/_fileName.class for dirname/fileName.jsp </b><br>
|
---|
55 | <br>
|
---|

|

58 | Example<br>
|
---|
59 | </h3>
|
---|
60 | <p>
|
---|
61 | <pre>
|
---|
62 | <target name="jspcompile" depends="compile">
|
---|
63 | <wljspc src="c:\\weblogic\\myserver\\public_html" dest="c:\\weblogic\\myserver\\serverclasses" package="myapp.jsp">
|

64 | <classpath>
|
---|
65 | <pathelement location="${weblogic.classpath}"/>
|

66 | <pathelement path="${compile.dest}"/>

74 | <h3>Limitations</h3>
|
---|
75 | <ul>
|
---|
76 | <li>This works only on weblogic 4.5.1</li>
|
---|
77 | <li>It compiles the files thru the Classic compiler only.</li>
|
---|
78 | <li>Since it is my experience that weblogic jspc throws out of memory error on being given too
|
---|
79 | many files at one go, it is called multiple times with one jsp file each.</li>
|
---|
