Hi,
I am trying to send some data via a servlet (using the examples from
this page "http://code.google.com/apis/visualization/documentation/dev/
dsl_intro.html" ). I can send all the data formats except the datetime
ones, not sure what I am doing wrong. here is a snippet of my code
cd.add(new ColumnDescription("Date Time", ValueType.DATE, "Date
Time"));
.... // some more columns
.... // get the data from a DB
DateValue date = new DateValue(2010,3,12); // Mock instead of using
true DB value
System.out.println("Date :" + date.toString()); // Seems correct get
"Date :2010-04-12"
data.addRowFromValues(date,tpid,serverTransactionId,transactionValue);
--> this lead to a an invalid type exception.
instead of using a date value if I use text and the date as a string
it works fine. Any pointers as to what I am doing wrong ?
( i looked at the code ValueType.java from the source file in example
repository and see this bit.
else if ((this == DATE) && (value instanceof GregorianCalendar)) {
ret = new DateValue((GregorianCalendar) value);
thought this is causing the failure
so tried adding this bit in my code
Object date = new DateValue(2010,3,12);
if(date instanceof GregorianCalendar)
System.out.println("Date true");
obviously if failed.
Thanks,
-V
