Cannot convert string to long

Whenever the getAsString function is called of timeConverter I am getting number format exception at line long timeMillis=Long.parseLong(time); I want to convert the given string to long.

1) Here is my timeConverter class

package com.converter;

import javax.faces.component.UIComponent;
import javax.faces.context.FacesContext;
import javax.faces.convert.Converter;
import javax.faces.convert.ConverterException;

public class TimeConverter implements Converter {

    @Override
    public Object getAsObject(FacesContext arg0, UIComponent arg1, String arg2) {
        return arg2;
    }

    @Override
    public String getAsString(FacesContext context, UIComponent component,
            Object value) {
        System.out.println("inside getAsString");
        String time=value.toString();

        long timeMillis=Long.parseLong(time);
        long currentTime=System.currentTimeMillis();
        long eclapseTime=timeMillis-currentTime;
        long secs=eclapseTime/1000;
        long days=secs/(60*60*24);
        long hours=(secs%(60*60*24))/60*60;
        long mins=(secs%(60*60*24)%(60*60))/60;
        long secs2=(secs%(60*60*24)%(60*60)%(60));
        StringBuffer sb = new StringBuffer();
        sb.append(days).append("days").append(hours).append("hours").append(mins).append("mins").append(secs2).append("secs");
        String object = sb.toString();
        return object;

    }

}

2) Here is stackstrace that I am getting.

The stack trace says you're using Integer.parseInt(...) rather than Long.parseLong(...). The number in the error message, "1348756490255" is much bigger than Integer.MAX_VALUE (2147483647).

It also says that the error occurs on line 37 of TimeConverter.java, and the source code you give doesn't even have 37 lines. You may have forgotten to both save in the editor and then recompile.

As a small aside, don't use StringBuffers. The Java compiler will convert String concatenations using + to use StringBuffer behind the scenes automatically.

You're getting this exception:

java.lang.NumberFormatException: For input string: "1348756490255"
...
  java.lang.Integer.parseInt(Integer.java:495)

Which means it's too long for integer. Max value for Integer is 2 147 483 647, so it fails on 134 875 649 025, which makes sense.

However, you're claiming that you're having the problem with this code:

long timeMillis=Long.parseLong(time);

which clearly isn't true, as per stack trace. Conclusion is that you're running a different code than you think you're running - parsing the string as long should work without issues. Long has a max value of 9 223 372 036 854 775 807 which is a lot more than you need.
