String to Date

[HBK32]

Hi,

 

I am passing date parameter as a type string in format i.e. "YYYY-MM-DD", now I want to display in format "MM/dd/yyyy" format. Problem is I am passing date field as String type parameter.

 

How can I convert it to into perticular format("MM/dd/yyyy") in iReports/Jasper internally as I will get date field as a String type!!!

 

Reply as soon as possible.

 

Thanks in advance,

Your Date field must be a Text Field (not Static Text) for this to work.

In case you have a static field, just do this:

Right click on the date field and select Transform in Text Field (F3).

This will convert your static text element into a text field element.

 

Now, right click your date text field.

Select properties and click on the Text Field tab.

In the Text Field Expression Class select java.util.Date.

I am assuming that you are passing a date parameter as you have mentioned.

In the Evaluation Time, select Now.

In the Pattern type in "MM/dd/yyyy" or whatever pattern you need.

Lastly, in the text field expression indicate the parameter that you are using like $P{importantDate}.

 

hth!

Hi,

 

Yes I am using TextField only.....I did the same thing as you mentioned but it is giving this following error....as parameter type is String

 

net.sf.jasperreports.engine.JRException:ÂErrorsÂwereÂencounteredÂwhenÂcompilingÂreportÂexpressionsÂclassÂfile: 1. Cannot cast from String to Date value = (java.util.Date)(((java.lang.String)parameter_StartDt.getValue()));

If your input String format is "YYYY-MM-DD", Let's assume $P{date} has the date in String.

 

 

(new GregorianCalendar(Integer.parseInt($P{date}.substring(0,4)),Integer.parseInt($P{date}.substring(5,7))-1,Integer.parseInt($P{date}.substring(8,10)))).getTime()

 

This will convert your String to java.util.Date Object. Then, you can specify Pattern such as dd/MM/yyy

Thanks a lot for your kind reply.....

Yes it works......I found following way which also works.

 

(new SimpleDateFormat("yyyy-MM-dd")).parse($P{StartDt})

 

Then in pattern Tab you can define what ever date format you want.....like e.g. MM/dd/yyyy

I tried this syntax and it is not working :(

 

This field is a string, and not a java.util.date

 

Is there any way i can convert a string to required date format?
