Hi,

    first i used with java.util.vector but after getting value from persistent store to convert string into long  i am getting number format exception...

     My requirement is storing a long value and retreiveing a long value..

[sonicboomboy]

there's nothing wrong to store long value in Vector.
If you put long number, then retrieve it, why there might be the error?
You should store your values like vector.addElement(new Long(long value));

then pls,tell me the syntac for retrieving long value from a vector of first element....

i need only first element ...

[sonicboomboy · Accepted solution]

Vector v = new Vector();
//fill vector
Long firstElement = (Long) v.firstElement();
long myLong = firstElement.longValue();
