Key: JBWS-800
URL: http://jira.jboss.com/jira/browse/JBWS-800
Project: JBoss Web Services
Issue Type: Bug
Security Level: Public(Everyone can see)
Components: jaxrpc
Affects Versions: jbossws-1.0.0.CR4
Environment: Windows XP, JBoss 4.0.4.CR2
Reporter: Chris Baxter
Assigned To: Alexey Loubyansky
Fix For: jbossws-1.2.0
I have a EJB3 persistent bean mapped to a Sybase DB table. This table has datetime
column that I have mapped back to a java.util.Date property on the persistent bean. This
same bean class is returned from a webservice call. On JBoss 4.0.3SP1 (using Axis), I had
no issues returning this object from my finder call. Now, when I switch to JBoss 4.0.4CR2
(using JBossWS), I get the following exception:
Caused by: java.lang.ClassCastException: com.sybase.jdbc3.tds.SybTimestamp

In looking at the source code, I think I see why there may be a problem:
else if(typeCode == XS_DATETIME)
{
Calendar c;
if(value.getClass() == java.util.Date.class)
{
c = Calendar.getInstance();
c.clear();
c.setTime((java.util.Date)value);
}
else
{
c = (Calendar)value;
}
result = marshalDateTime(c);
}
The SybaseTimestamp class extends java.sql.Timestamp which in turn extends
java.util.Date. That first 'if' should hit, but it won't because
SybaseTimestamp.class != java.util.Date.class. Instead, I think the if statement should
be:
if(java.util.Date.class.isAssignableFrom(value.getClass()))
I made this change and recompiled and everything works as expected now.
