I am working on an application where I am replacing the login.jsp with my login.zul.

Login.zul

<window id="loginWin" title="Login" border="normal" width="400px" top="100px" style="margin-left:auto;margin-right:auto;margin-top:150px" >
<h:form id="loginForm" action="j_security_check" xmlns:h="http://www.w3.org/1999/xhtml">
<grid>
<rows>
<row>LoginID : <textbox id="j_username"/></row>
<row>Password : <textbox id="j_password" type="password" constraint = "no empty"/></row>
<row><button label="submit" onClick="login()"/></row>
</rows>
</grid>
<zscript>
void login() {
Clients.submitForm(loginForm);
}
</zscript>
</h:form>
</window>

I am getting this error on doing so :
