Thanks.
I have the following code and it works:
public Vector getAnnotations(Document doc, String field, String value)
throws XWikiException
{
Vector result = new Vector();
Vector allObjects = doc.getObjects("AnnotationClass");
if (allObjects == null || allObjects.size() == 0) {
return result;
} else {
int limit = allObjects.size();
for (int i=0; i<limit;i++)
{
Object obj = ((Object)allObjects.get(i));
if(obj != null)
{
Property prop = (Property) obj.getProperty(field);
if (prop != null && prop.getValue()!=null &&
value.equalsIgnoreCase((String)prop.getValue()))
{
result.add(obj);
}
}
}
}
return result;
}

Here, allObjects contains API wrappers, and not internal objects, so you
don't have com.xpn.xwiki.object.BaseObject there, but
com.xpn.xwiki.api.Object
In that case you must use this check:
if (value.equalsIgnoreCase((String)((Property)
obj.getProperty(field)).getValue()))
The problem is that now you will get the same NullPointerException as
above. I told you to check if the result of obj.get is null, so you must
do something like:
Property prop = (Property) obj.getProperty(field);
if (prop != null && value.equalsIgnoreCase(prop.getValue())) {
