Thanks for the quick response
>> Obviously either getOptions() or getTldCache() is returning null.
I debug the code as you suggest and found that getTldCache() is null.
In the code As I understand there are 2 point which set the *tldCache*
variable
one is the setTldCache() method and other is
public static TldCache getInstance(ServletContext servletContext) {
if (servletContext == null) {
throw new IllegalArgumentException(Localizer.getMessage(
"org.apache.jasper.compiler.TldCache.servletContextNull"));
}
return (TldCache)
servletContext.getAttribute(SERVLET_CONTEXT_ATTRIBUTE_NAME);
}
from this 2 methods I couldn't find any point that setTldCache() is been
used. So I think getInstance() is the method that is been used.
Should I manually set the value o tldCache?
Thanks
