Hi Volker,
You can do it with struts xml validator:
Include a xml into your action package like this:
ActionName - alias from action - validation.xml
Example:
ActionName-save-validation.xml
* Note that "save" is the name of action in your struts.xml
Nothing better than a real example:
struts.xml -------------------------------------------------------
<action name="salvar" method="salvar"
class="br.com.sgvdba.actions.usu.UsuAction">
<result name="success" type="redirectAction">
<param name="idUsu">${currentUsu.cd}</param>
<param name="actionName">abrirDados</param>
<param name="namespace">/usuario</param>
</result>
<result type="tiles" name="input">default.usu</result>
</action>
UsuAction (Action class) -----------------------------------------
/**
* Persiste determinado usuário no banco de dados
* * Para inserir um usuário deve ser confirmada a não-existência
* de outro registro com o mesmo nome de usuário.
* @return
*/
public String salvar(){
//Verifica se a tela possui erros
if (hasFieldErrors() || hasErrors()){
return Action.INPUT;
}
try {
if (!getUsuFacade().isSenhaValid(currentUsu.getSenha(),
senhaConf)){
addActionError("As senhas informadas devem ser iguais");
return Action.INPUT;
}
else
if (!getUsuFacade().isChvValid(currentUsu.getChv())){
addActionError("Já existe um usuário com este nome,
favor informar um nome diferente");
return Action.INPUT;
}
else {
NvlAcso nvlAcso =
getNvlAcsoFacade().recuperaPorId(idNvlAcso);
getUsuFacade().incluir(currentUsu, nvlAcso);
setIdUsu(currentUsu.getCd());
}
} catch (Exception e) {
addActionError(SgvdbaConstants.ERRO_DEFAULT + e.getMessage());
return Action.INPUT;
}
return Action.SUCCESS;
}
UsuAction-salvar-validation.xml (VALIDATION)
-------------------------------------------------------
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE validators PUBLIC "-//OpenSymphony Group//XWork Validator 1.0//EN"
"http://www.opensymphony.com/xwork/xwork-validator-1.0.dtd";>
<validators>
<field name="currentUsu.chv">
<field-validator type="requiredstring">
<message>Favor inserir um nome de usuário</message>
</field-validator>
</field>
<field name="currentUsu.email">
<field-validator type="requiredstring">
<message>Favor inserir um e-mail</message>
</field-validator>
<field-validator type="email">
<message>Favor informar um e-mail válido</message>
</field-validator>
</field>
<field name="currentUsu.senha">
<field-validator type="requiredstring">
<message>Favor inserir uma senha</message>
</field-validator>
<field-validator type="stringlength">
<param name="minLength">4</param>
<param name="maxLength">12</param>
<param name="trim">true</param>
<message>A senha deve conter no mínimo ${minLength} e no
máximo ${maxLength}</message>
</field-validator>
</field>
</validators>
Hope this can help you.
