というエラーが出て困っています。ModeSelectForm.javaの「DbRenewalForm dbRenewalForm = (DbRenewalForm)form;」ところでキャストがうまくできていないのだと思いますが解決法が思いつきません。
どうしたら解決できるでしょうか？

struts-config.xmlのformの設定が
DbRenewalFormを参照するようになっていないんじゃないですか？
最近Strutsをやってないので、細かい設定は忘れましたが。

かつのりさん、ありがとうございました。
かつのりさんの御指摘通り、struts-config.xmlのForm Beanの設定を変えたところ上手く動きました。
