Re: [jboss-as7-dev] Issue in EJB ?

This one really doesn't have to do anything with Webservice or EJB. It's plain JAXP issue within AS7. Here's a bean/testcase which easily reproduces it https://github.com/jaikiran/jboss-as/commit/4e25a7771698c4745ac7594679f73.... Here's the relevant part from that EJB code: @Stateless public class StatelessWSAccessingDataTypeFactory { private static final Logger logger = Logger.getLogger(StatelessWSAccessingDataTypeFactory.class); private static final Duration duration; static { try { duration = DatatypeFactory.newInstance().newDuration(86400000L); ... } This results in a CNFE http://pastebin.com/3tgtrhnx. The important piece here is the static initialization block of the bean. This gets invoked during the deployment stage when the TCCL is null. The JAXP DataTypeFactory relies on TCCL to be set. If the TCCL is null it just throws a CNFE, like it does here, instead of falling back on the system classloader. This probably is a bug in JAXP, since from what I see the JAXP XMLInputFactory falls back to system classloader in the absence of TCCL being set. @see javax.xml.stream.SecuritySupport.getContextClassLoader() and compare it to the buggy(?) javax.xml.datatype.SecuritySupport.getContextClassLoader(). I think the DataTypeFactory should be falling back to system classloader in the absence of TCCL. Thoughts? How do we fix this? As for a workaround, Jim, moving that static initialization into a @PostConstruct method should get you past this issue. -Jaikiran On Saturday 23 July 2011 10:26 AM, Jaikiran Pai wrote: > Missed this thread.
