Java.lang.IllegalArgumentException: Cannot format given Object as a Date - Ajuda!

Front-end
#1

Pessoal,

Quando eu envio as informações do form para o servlet, aparece esse erro. Já tentei várias coisas, mas não consigo resolver, alguém pode me ajudar?

Erro:

java.lang.IllegalArgumentException: Cannot format given Object as a Date
	java.text.DateFormat.format(Unknown Source)
	java.text.Format.format(Unknown Source)
	servlets.TdpAltera.processRequest(TdpAltera.java:52)
	servlets.TdpAltera.doPost(TdpAltera.java:87)
	javax.servlet.http.HttpServlet.service(HttpServlet.java:637)
	javax.servlet.http.HttpServlet.service(HttpServlet.java:717)

Estou enviando meu código para quem puder me ajudar, dar uma olhada no que poder estar errado.

Cara,

Olhando o stack trace você mesmo pode achar a resposta: “servlets.TdpAltera.processRequest(TdpAltera.java:52)”.

Se você estiver utilizando alguma IDE faça um debug da sua aplicação e tente verificar o que acontece na linha 52 da classe TdpAltera.
