I used the following EJB-QL in the dynamic query search (I tried it in finder
method and it worked):
"select object(a) from TestDateSchema as a where a.tstampDate > ?1 and
a.tstampDate < ?2" --- where a.tstampDate is java.sql.Timestamp and two
arguments (?1 = start date and ?2 = end date)...
...and here is the statement to get a collection...
java.sql.Timestamp gotTimestamp;
Collection lc = myBeanHome.getGeneric(jbossql.toString(), args);
...and Iteration and while loop...
while(iter1.hasNext()){
TestDateLocal mydate = (TestDateLocal)iter1.next();
gotTimestamp = mydate.getTstampDate(); // This statement returns error
} }
TestDateLocal (extends EJBLocalObject) has the getTstampDate method and this
method returns the following message:
java.lang.NullPointerException
at org.jboss.ejb.plugins.local.EntityProxy.invoke(EntityProxy.java:44)
at $Proxy1.getKey(Unknown Source)
at com.testdate.TestDateClient.testBean(TestDateClient.java:127)
at com.testdate.TestDateClient.main(TestDateClient.java:145)
I had checked entire EJBsrc folder for all files but I came up nothing...Please
let me know if you have encountered this problem before.
Thanks...
