Hello,
Can it be this the source of the problem?
DynaBean row = (DynaBean) it.next();
DynaBean rowCopy = bdc.newInstance();
PropertyUtils.copyProperties(row, rowCopy);
I guess when u use copyProperties the destination come
First, and the source second....
Thus rowcopy does not get populated correctly
Hope this helps
Regards
marco

Subject: DynaBeans and ResultSetDynaClass
Hi there! I'm using dynabeans and resultSetDynaClass to
retreive a resultset from a database. As the sources of
this classes are very rare, I got my self into a
problem. Here's some line of code:
ResultSetDynaClass rsdc = new
ResultSetDynaClass(rs);
DynaProperty properties[] =
rsdc.getDynaProperties();
BasicDynaClass bdc = new
BasicDynaClass("dynaBean", BasicDynaBean.class, properties);
Iterator it = rsdc.iterator();
try {
while (it.hasNext()) {
DynaBean row = (DynaBean) it.next();
DynaBean rowCopy = bdc.newInstance();
PropertyUtils.copyProperties(row, rowCopy);
results.add(rowCopy);
}
}
The SQL statement is the following : "SELECT id_forum,
theme, status FROM forum".
And then I try to use this in this way:
Collection cll = queryRunner.executeDynaQuery(query,
dataSource);
Iterator it = cll.iterator();
while(it.hasNext()){
DynaBean forum = (DynaBean)it.next();
System.out.println(forum.get("theme").toString());
}
But I'm getting a null pointer exception. When I debug,
I noticed that the collection comes with all results
expected (in numbers). The Hashtable inside the object
do have the properties (theme, id_forum and so on) but
they all have null values.
Any ideas????
Thanks a lot
Vinicius Carvalho
