>Release: Apache 1.3.3
>Environment:
JServ 1.0b1 1998-12-19 and JServ-SSI 1.0
Windows NT 4.0 SP3
JDK 1.1.6
>Description:
JServSSI.getParameter(String name) throws a NullPointerExecption if
req.getParameterValues(name) returns null (it does if the page is
requested without parameters).
>How-To-Repeat:
Use the <SERVLET> tag without <PARAM> tags to invoke a servlet on
a page requested without any request parameters.
>Fix:
The following modified version of the method works:
public String getParameter(String name) {
String value = (String) params.get(name);
String rvalues[] = req.getParameterValues(name);
// Added null test below
if (rvalues == null) return value;
return (value != null) ? value : (rvalues.length > 0 ? rvalues[0] :
null);
}
