Summary: JasperException: Unable to load MyDecorator.class
Initial Comment:
- Tried to adapt the org.displaytag.sample.TotalWrapper
and got the below stack trace.
- checked my war - the .class file is in there!
- Even added test method
public static void isClassThere() {
log.debug("class is there!");
System.out.println("sys: class is there!");
}
and called it in my jsp one line before my display
tags start:
<<
<%
com.privasphere.privalope.util.BillTotals.isClassThere();
%>
>>
As to be expected, nicely got
<<DEBUG [Thread-5] (BillTotals.java:30) - class is there!
sys: class is there!>> in my catalina.out
What am I doing wrong?
http://sourceforge.net/mailarchive/message.php?msg_id=7054216
doesn't really seem to be the same.
If there is the need to tell displaytag to add to the
path, please document this in
http://displaytag.sourceforge.net/tagreference.html.
Any help would be highly appreciated!
Ralf

no details have been added since the bug was opened: now the
root exception is added to the error message and should help
in solving the issue. I'm closing the bug as a "cannot
duplicate": please submit a new bug with more details if you
still get this problem.

Got the same problem... I had to move my decorator to the
displaytag-XXX.jar file and restart Tomcat to get it to work

I can't reproduce this.
Can you please check the log for the previous exception?
Displaytag should also log the cause for this, which can be a
ClassNotFoundException, InstantiationException,
IllegalAccessException, or ClassCastException.
Please add an addictional comment here with this information
and I will try to fix is as soon as possible.

copying the com.privasphere.privalope.util.BillTotals to
tomcat/shared/lib/com/privasphere/privalope/util/BillTotals.class
as per
http://sourceforge.net/mailarchive/message.php?msg_id=6732242
didn't solve it either.
Probably, it would be good to be able set a
classpath-amending display-tag property such that I wouldn't
have to bother about this!
