Servlet error after deploy to app server

Question

Hi,
When I run my jheadstart app from local pc then everything is fine. When I deploy the same app to the app server it starts correctly, and works somehow. But, when I click the new button in any kind of jsp, I get the following error:
05/05/18 09:58:19 Started
05/05/18 09:58:27 ilbi: jsp: init
05/05/18 09:58:28 ilbi: action: init
05/05/18 09:58:29 ilbi: uix: init
05/05/18 09:58:31 ilbi: 9.0.4.1.0 Started

I think this is a deployment problem and I tried to resolve used the deployment issue on this forum (I made the ADF Runtime manual installation steps), but at this moment I have no idea.
Could anybody help me, please?
thanks

Hi,
Here are the codes:
OLD CODE:
protected void create(AttributeList attributeList)
super.create(attributeList);
setOwnerId(AdfbcUtils.getValueFromSequence("ILB_OWNERS_S", getDBTransaction()));
NEW CODE
protected void create(AttributeList attributeList)
super.create(attributeList);
setOwnerId(getSeqNum("ILB_OWNERS_S", getDBTransaction()));
getSeqNum:
PUBLIC NUMBER getSeqNum(String sequenceName, DBTransaction tr) {
STATEMENT st = NULL;
ResultSet rset = NULL;
NUMBER retVal = NULL;
try {
String stmt = "select to_char(" + sequenceName + ".nextval) from dual" ;
st = tr.createStatement(1);
rset = st.executeQuery ( stmt );
WHILE (rset.NEXT())
retVal = NEW NUMBER(rset.getString(1));
logger.DEBUG("Sequence captured");
RETURN retVal;
} catch (SQLException s) {
logger.DEBUG("Sequence not captured because error occured");
throw NEW JboException(s);
} finally {
try {
IF (st != NULL) st.CLOSE();
} catch (SQLException s) { /* ignore */ }
