it has to display using another loop. My requirement is I want to store only in
Object[] array but not in any other data type. Its compiling but giving run time error
in the following line. Can anybody give their suggestion or recode the below.
lo_oName = (Object[ ]) lo_arrListName.get(i); //giving error here in runtime.
/* FullCode */
import java.util.*;
public class Generic {
public static void main ( String args[ ] ) {
Object lo_oName[] = null;
ArrayList lo_arrListName = new ArrayList();
lo_arrListName.add(HAPPY BIRTHDAY TO YOU...);
lo_arrListName.add(YOU ARE NOT YOU YOU ARE HE...);
lo_arrListName.add(THE GOD...);
lo_arrListName.add(PRAY HIM DEEPLY PEACEFULLY...);
lo_arrListName.add(HE GIVES ALL TO YOU...);
/*lo_arrListName.add(new Integer(100));
lo_arrListName.add(new Integer(200));
lo_arrListName.add(new Integer(300)); */
int i = 0;
System.out.println ( lo_arrListName.size());
while (ilo_arrListName.size() )
{
System.out.println ( In the while loop. );
lo_oName = (Object[ ]) lo_arrListName.get(i);
System.out.println (After storing the arraylist value in Object variable..);
System.out.println (Value in object... + lo_oName[i].toString() );

*) I am uploading a file using MultipartRequest class given by third party. Now my file is uploading to specific position. My problem whenever the file is uploading, if any problems comes in uploading immediately it should be monitor using a table or file. That means When i click upload the file uploading to specific location now, if any problems raises inbetween uploading like system restarted,connection failed,location is full so file doesnot have space. So I have to capture that error information. Can anybody help me ? 2) I am loading a java object into oracle procedure using the follwoing ways ? 1 ) javac program.java 2) then moving oracle directory and saying loadjava classname. 3) It is successfully loaded . And in my procedure i am calling that object and executing object.functionname(). But the procedure rasing an error some CLASSno121 not found. What my doubt is is their compability needed between java and oracle that means the jdk1.3 works only on oracle8.1 or 7.1. This is very important concept. Don't feel anybody that calling a java object in oracle is not possible . This is already done in my earlier companies. And it is there in oracle tuturials which i have seen in internet. Can anybody solve this problem ? - Do you Yahoo!? New Yahoo! Photos - easier uploading and sharing
