Hi,
I switched to org.apache.tomcat:tomcat-jasper-el:8.0.0-RC1 as javax.el 3.0
implementation and tested with the following code:
ELProcessor processor = new ELProcessor();
processor.getELManager().importClass("java.io.File");
processor.eval("File('./')");
but I get the following error:
javax.el.ELException: Function ':File' not found
at org.apache.el.parser.AstFunction.getValue(AstFunction.java:136)
at
org.apache.el.ValueExpressionImpl.getValue(ValueExpressionImpl.java:188)
at javax.el.ELProcessor.getValue(ELProcessor.java:129)
at javax.el.ELProcessor.eval(ELProcessor.java:115)
at
org.apache.naming.factory.ExpressionFactoryTest.elImplementationShouldWork(ExpressionFactoryTest.java:43)
Are methods importClass, importStatic and importPackage on ELManager already
implemented in apache EL?
Regards,
Xavier
