[jira] Created: (WW-2471) NPE in
XWorkConverter.loadConversionProperties after adding DateConverter is still
not fixed in 2.1.0
NPE in XWorkConverter.loadConversionProperties after adding DateConverter is still not fixed in 2.1.0
-----------------------------------------------------------------------------------------------------
Key: WW-2471
URL: https://issues.apache.org/struts/browse/WW-2471
Project: Struts 2
Issue Type: Bug
Affects Versions: 2.1.0
Reporter: Sami Dalouche
Same problem as : WW-1978, the problem is still not fixed in 2.1.0, nor in 2.1.1-SNAPSHOT
when xwork-conversion.properties contains an entry, Struts 2 startup throws a NPE :
[ERROR] [2008-02-03 17:09:16,181] [com.opensymphony.xwork2.conversion.impl.XWorkConverter] (main,) : Conversion registration error
java.lang.NullPointerException

at com.opensymphony.xwork2.inject.ContainerImpl$ParameterInjector.inject(ContainerImpl.java:431)
at com.opensymphony.xwork2.inject.ContainerImpl.getParameters(ContainerImpl.java:446)
So, it looks like the object factory is not set in XWorkConverter :
Object obj = objectFactory.buildBean(className, null);
Is there a quick work-around ?

Sami Dalouche commented on WW-2471:
-----------------------------------
The work-around I found was to move the converters to some other properties file (xwork-conversion-hack.properties, for instance), and to make sure the code is loaded before any action executes, by creating a filter such as :
public class Struts2HackFilter implements Filter {
boolean initialized = false;
public void destroy() {
// TODO Auto-generated method stub
}
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain filterChain) throws IOException, ServletException {
if(!initialized) {
initXWorkConverter();
initialized = true;
}
filterChain.doFilter(request, response);
}
public void initXWorkConverter() throws ServletException {
try {
XWorkConverter xworkConverter = Dispatcher.getInstance().getContainer().getInstance(XWorkConverter.class);
xworkConverter.loadConversionProperties("xwork-conversion-hack.properties");
} catch(IOException e) {
throw new RuntimeException(e);
}
}
public void init(FilterConfig arg0) throws ServletException {
// TODO Auto-generated method stub
}
and of course, it is necessary to map it in web.xml AFTER struts2 filter
<filter-mapping>
<filter-name>struts2hack</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
This is the temporary solution I am using in the meanwhile....
