VO Errors ,,,,, procedurejava.lang.sql.exception & Java.lang.NullPointerExc

Question

Hi All,
I have extended the standard CO.
Below is my code.
processRequest(OAPageContext pageContext,OAWebBean webbean)
super.processRequest(pageContext,webbean);
processFormRequest(OAPageContext pageContext,OAWebBean webbean)
super.processRequest(pageContext,webbean);
String evt = pageContext.getParameter(OAWebBEanConstants.EVENT_PARAM);
OAApplicationModule oaapplicationmodule = pageContext.getRootApplicationModule();
OAViewObject vo = (OAViewObject)oaapplicationmodule.findViewObject("DisplaydetailsVO");
if(vo!=null)
vo.first();
String fwk = pageContext.getParameter("Runid"); *// If i use this statement to call the attribute value then Error 1 i am getting*
(or)
String qaz = (String)vo.getCurrentRow().getAttribute("Runid") *// If i use this statement to call the attribute value then Error 2 i am getting*
if(event.equals("GO")
try
CallableStatement callablestatement = (oracleCallableStatement)oaapplicationmodule.getOADBTransaction().createCallableStatement("begin purchase_po_wf.purchasing_vision_wf(:1); end;",1);
callablestatement.execute();
callablestatement.setString(1,fwk);
callablestatement.setString(1,qaz);
callablestatement.close();
callablestatement.close();
Catch(SQLException ex)
Please suggest me which statement to use call the Attributes & VO . Please do let me know if anything is wrong in the code.
I am getting the below errors :
1. Cannot call the procedurejava.lang.sql.exception Method in & out parameters extends::1
2. Java.lang.NullPointerException
Can any one please help me out , to overcome this issue. Its bit urgent

Hi Kalyan,
So you want to get the value of DisplaydetailsVO.Runid attribute
and then use it for calling a package?
and the attribute is Runid or RunId
you can put the below code to get all the attributename and its values in the VO.(change the VO, AM names according to your customizations)
Then you can get what should be attributeName you should be using it, and I am not sure about your requirement, you might need to call before super.processFormRequest().
Get all the attribute from a VO with Attribute Names in Custom CO
OAApplicationModule rootAM = pageContext.getRootApplicationModule();
OAApplicationModule apprAM = (OAApplicationModule)rootAM.findApplicationModule("AppraisalsAM");
String offlineStatus = (String)apprAM.invokeMethod("getOfflineStatus",new Serializable[]{appraisalId+""});
OAViewObject appraisalVO = (OAViewObject)apprAM.findViewObject("AppraisalVO");
if(appraisalVO !=null)
AppraisalVORowImpl appraisalVORow = (AppraisalVORowImpl) appraisalVO.first();
if(appraisalVORow !=null)
int attrCount = appraisalVO.getAttributeCount();
writeLog("XXRBG",pageContext,"Attrbuute count "+attrCount);
String[] attributeNames = appraisalVORow.getAttributeNames();
for (int i = 0 ;i< attributeNames.length ;i++ )
writeLog("XXRBG",pageContext," Name "+attributeNames[i] +" = "+appraisalVORow.getAttribute(i));
Thanks,
With regards,
Kali.
