Unable to compile class for JSP

Thu, 30 Sep 2004 01:30:09 -0700 

Hi

I had some pb my my projects jsps. I am obliged to precompile them.
I tried to get the same problem with a small appli.

I write a very simple jsp :

<html>
<body>
<%java.util.Date d = new java.util.Date();%>
Todays date is <%= d.getDate()%>  hello!
</body>
</html>

When I start tomcat everythings seems ok,

When I launch the page I have the same problem :

*an exception*

org.apache.jasper.JasperException: Unable to compile class for JSP


*root cause*

java.lang.SecurityException: class 
"org.apache.tools.ant.taskdefs.optional.IContract"'s signer information does not match 
signer information of other classes in the same package


Full error page below.

Any help appreciated

Best regards

Andre
