Summary

0000100: Exception when calling EL methods from JSP

Description

RSN-91
I have just made my first function call-back from JSP to Java. My code works in Tomcat 5.0.28 but fails in Resin 3.0.12 with the following exception

java.lang.IllegalArgumentException: argument type mismatch

From what I can see in the debugger the problem may be that the Method.invoke gets incorrect arguments.

The TLD description is

        <function-signature>
            java.lang.String formatNumber(java.lang.Double, int, char, int)
        </function-signature>

and the argument passed in Method.invoke contains is displayed in Eclipse as a [Double, Integer, ",", Integer].

The JSP-snippet is

${axs:formatNumber(123.456789, 0, ',', 3) }

Steps To Reproduce

Additional Information

Windows XP, java 1.4.2_08
