passing parameters from wml to servlets. help!!

hey guyz,
i am new to wap/wml programming. I hope somebody would be able to help me out.I keep getting a syntax error in my servlet but i cant seem to find it.My logic (sql statements are in the member.java).This is suppose to be a login function. Would somebody kindly tell me where im going wrong in my servlet ? Im using the deckit simulator to run the wml pages.

Login.wml

out.println("</select>");
out.println("</p>");
out.println("</card>");

out.close();
}
}
catch (UserException se) {
se.printStackTrace();
}
}
}

I should advice u to pass the variables with a dynamic language ( JSP o servlets) and generate your WML Code with this.
According to me, it s easier
Hope it helps
