JSPs with custom components will not compile
All,
I have written a custom component, but am having trouble getting it to work. When i place it in a jsp or jspx and try to run the application using this control, i get compilation errors:
org.apache.jasper.JasperException: Unable to compile class for JSP

After fighting with this for a while, I tried the following:
1) Copy code from a known-working example into the existing web app
2) Copy the code for the component et al into the known working example app
results:
1) Known working component generates the same compilation errors
2) everything work correctly
I have compared the tlds and faces-config.xml files and everything appears to be correct. In both cases, the faces-config.xml files are at version 1.2 and the tlds are at version 2.1
The only difference i can see is that the not-working web app uses far more libraries than the working example, though i'm not sure why this would be a problem.
From the not working webapp:
