Java.lang.ClassCastException in Custom VO

Question

I have created custom VO and made as such that it will display the Text Box “Carrier Charge” . Now I am extending the Controller of this region as such the value that is been entered in this text field needs to stored in the Database. For this, we need to know the line id and so with that line id we can store the carrier charge in database. For taking the current line id, I am referring the XXPosViewLinesVORowImpl.java.
I have coded my custom java file also to take from the region” PosOrderLines”. My coding is below.
public void processFormRequest(OAPageContext oapagecontext, OAWebBean oawebbean)
throws OAException
//super.processFormRequest(oapagecontext, oawebbean);
OADBTransaction oadbtransaction = getApplicationModule(oapagecontext, oawebbean).getOADBTransaction();
OATableBean oatablebean = (OATableBean)oawebbean.findChildRecursive("PosOrderLines");
int x= 0;
int y= 0;
int z= 0;
String s5 = null;
if(oatablebean != null)
OAInnerDataObjectEnumerator oainnerdataobjectenumerator = new OAInnerDataObjectEnumerator(oapagecontext, oatablebean);
for(int k = 0; oainnerdataobjectenumerator.hasMoreElements(); k++)
RowSet rowset = (RowSet)oainnerdataobjectenumerator.nextElement();
if(rowset != null)
y++;
XXPosViewLinesVORowImpl posviewlinesvorowimpl = (XXPosViewLinesVORowImpl)rowset.first(); //It shows castException here……..
if(posviewlinesvorowimpl != null)
try
storeAttribute16(posviewlinesvorowimpl,oadbtransaction);
// String firstAttribute16 = PosServerUtil.replaceNull(posviewlinesvorowimpl.getAttribute("Attribute16"));
catch(Exception e)
e.printStackTrace();
for(int i1 = 0; rowset.hasNext() && i1 < rowset.getFetchedRowCount(); i1++)
z++;
XXPosViewLinesVORowImpl posviewlinesvorowimpl1 = (XXPosViewLinesVORowImpl)rowset.next();
if(posviewlinesvorowimpl1 != null)
try
storeAttribute16(posviewlinesvorowimpl1,oadbtransaction);
// String nextAttribute16 = PosServerUtil.replaceNull(posviewlinesvorowimpl1.getAttribute("Attribute16"));
catch(Exception e)
e.printStackTrace();
throw new OAException(y+" Times "+z+" Times"+z+" Times"+" "+s5, OAException.INFORMATION);
====
In my file it shows error in the line marked. ClassCastException is shows. I have only created custom VO and haven’t created custom AM. Whether it may be the reason for this error.

Please help me to solve this, is there any other way to get the attributes from the RowImpl.java?
Thank you,

Answer 1

Also i have seen this code in some java file,
====
PosViewLinesVOImpl posviewlinesvoimpl = getPosViewLinesVO();
RowSetIterator rowsetiterator1 = posviewlinesvoimpl.findRowSetIterator("lines");
if(rowsetiterator1 == null)
rowsetiterator1 = posviewlinesvoimpl.createRowSetIterator("lines");
if(posviewlinesvoimpl.isPreparedForExecution())
while(rowsetiterator1.hasNext())
PosViewLinesVORowImpl posviewlinesvorowimpl = (PosViewLinesVORowImpl)rowsetiterator1.next();
ArrayList arraylist2 = posviewlinesvorowimpl.getExceptions();
if(arraylist2 != null)
arraylist1.addAll(arraylist2);
if(posviewlinesvorowimpl.isDirty())
Object aobj2[] = new Object[51];
getLineChanges(s, s1, s2, s3, posviewlinesvorowimpl, arraylist, aobj2);
rowsetiterator1.closeRowSetIterator();
=====
Here i think that they are fetching the row attributes from the VO PosViewLinesVOImpl.java....
Can i use similar code for my case, if its possible, what is this?
posviewlinesvoimpl.createRowSetIterator("lines");........... In this line they are separating the lines. what for they have hardcoded like this "lines". is its for gettign the lines, can i do similar like this.......
I am not familiar in OAF and this is my first component in this!!!!
Please reply me.....
Thank you,
