Hi All,


I need help as we are processing files which is having a size less than 1MB and we are getting an output in one file but
we need an output in a tabular form like this .
Here Field1 and Field2 are headers and then their respective values should come in another line by reading each respective file, example given below.

Input file1

field1 : data
field2 : data
field3 : data

Input file 2

field1 : data
field2 : data
field3 : data

final Output

Field1 Field2 Field3
Data Data Data ( File 1 Data)
Data Data Data (File 2 Data)
Data Data Data (File 3 Data)

Hi Vinod ,


Thanks and If Im correct I need to put this in persistence.xml file and this seeting will help me to print the query which is created at runtime by JPA.
Please correct me ifIm wrong.

Thanks alot
Hi All,



In our project we have used EJB3.0 and JPA and while working on this we need to see the sql queries formed by JPA
which can help us what joins are getting establish and locks so that we can improve our query, so I need to know
how to see the sql query formed by JPA at run time .
These are the queries

@NamedQuery(name = DetectionEvent.RETRIEVE_DE_LIST_FOR_REPROCESSING, query = "SELECT DISTINCT de "
+ " FROM DetectionEvent de " + "WHERE de.reprocessDE = '" + LrucConstants.DB_YES
+ "' ORDER BY de.chargePointId, de.captureDatetime ASC"),

and this is a method


public List<SummaryRecord> getSRsRequiringRejection(Timestamp pStartTime, Timestamp pEndTime)
{
logger.trace("Entry:getSRsRequiringRejection");
// UC-CORE-ASS002 Reject Detection event
// This retrieves a list of SummaryRecord entities from the
// SUMMARYRECORD
// table in the EventAndVURDAO where the ‘requiresRejection’ flag is
// set.
Query query = mEntityManager.createNamedQuery(SummaryRecord.RETRIEVE_SUMMARY_RECORD_LISTS);
query.setParameter(SummaryRecord.PARAM_START_TIME, pStartTime);
query.setParameter(SummaryRecord.PARAM_END_TIME, pEndTime);
List<SummaryRecord> summaryRecord = query.getResultList();
return summaryRecord;
}
Need to see complete query which is getting generated at runtime so that I can see locks and joins on the table so that w ecan make improvements ..
Please tell us how to acheive this in JPA.

Thanks in advance.

Hi All,

I'm trying to run class having a below method but getting an exception while running. I have check but wnat to know what is wrong so that I make necessary correction to fix this exception.
SPRING_CONTEXT_FILE: ist is a string variable pointing to application.xml file.

public static void main(String[] pArgs)
{
try
{ System.out.println(" starting ");
ApplicationContext ctx = new ClassPathXmlApplicationContext(SPRING_CONTEXT_FILE);
System.out.println("before applicationbean name");
CoreBatchVehicleListApp app = (CoreBatchVehicleListApp) ctx.getBean(APPLICATION_BEAN_NAME);
System.out.println("After applicationbean name");
// get the key framework instances if any of these are missing we will get a runtime exception

The validate () method doesnt exist in servlet API rather these methods are from 3rd party like in struts where we can use the validate framaework and can the files which you have mentioned .

In validator-rules .xml we define the validation condition of the fields of our form and call then call
validate method to validate form in struts validator_rules.xml in our action class. We need to give path of all these configuration files in our web.xml file.

See some example of struts validator and runt that example and you will be able to understand well.

Hi All,

In my application I need to show dynamic services and this dynamic services should also show default services in the list.

So user will see some of the selected checkbox which will indicates that these are default services which he will get and rest of the services will be with unchecked checkbox.
So Iam using <h:selectManyCheckbox > for this and I am using two list to achieve this the code is given below.

A) value="#{cartBean.highendSelectedArrList} this is a default service_id list which will show the checkbox selected as checked
whereas <f:selectItems value="#{cartBean.highendservices}" /> highendservices is a list which has list of all the service lis.


<h:selectManyCheckbox id="highend" value="#{cartBean.highendSelectedArrList}" border="1" layout="lineDirection">
<f:selectItems value="#{cartBean.highendservices}" />

</h:selectManyCheckbox>


My question is that can you suggest the way so that I dont need to make two list rather one list I can show the use default services for him as well as rest of the services then user make selection and can retrieve the values easily.
