Error on ArrayList

[RicardoPereira]

I'am trying to display all the records from a table to my jsp page without requesting parameters (without forms), but i'am getting always the same erros message.


org.apache.jasper.JasperException: ControloBD.ControloQualidadeBD.getTblErros()Ljava/util/ArrayList;
at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:254)
at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:295)

at javax.servlet.http.HttpServlet.service(HttpServlet.java:853)


...







I have an jsp file with a bean that access a class file.

Jsp file:
---------


<%@page contentType=&quot;text/html&quot; import=&quot;java.util.ArrayList, entidades.*&quot; %>
<jsp:useBean id=&quot;pesquisas&quot; scope=&quot;request&quot; class=&quot;ControloBD.ControloQualidadeBD&quot; />
<HR><center><table border=0 cellspacing=1 cellpadding=2 bgcolor = &quot;#eeeeee&quot;>
<tr bgcolor=&quot;#eeeeee&quot;><td class=&quot;smallerheader&quot;><font class=&quot;smallerheader&quot;>
<b>Código Erro</b></font></td><td class=&quot;smallerheader&quot;><font class=&quot;smallerheader&quot;><font class=&quot;smallerheader&quot;>
<b>Descrição Erro</b></font></td></tr>

<%
ArrayList listaTErro=pesquisas.getTblErros();
for( int x=0;x<listaTErro.size();x++)
{
Tbl_Erros TErro=(Tbl_Erros) listaTErro.get(x);
out.println(&quot;<tr bgcolor='#ffffff'>&quot; +
&quot;<td><p align='center'>&quot; + TErro.getQ3CODERRO() +
&quot;</p></td><td class='smallertext'><font color='#9b301c'><b><p align='center'>&quot; + TErro.getQ3DESCERRO() + &quot;</p></b></td></tr>&quot;
}
%>
</table></center><HR>


Method getTblErros in class ControloQualidadeBD
-----------------------------------------------

public ArrayList getTblErros() throws SQLException {
ArrayList res=new ArrayList();

Statement stmt = con.createStatement();
ResultSet rslt = stmt.executeQuery(&quot;select Q3CODERRO, Q3DESCERRO from Tbl_Erros&quot;

while (rslt.next()) {
res.add(new Tbl_Erros(rslt.getString(1), rslt.getString(2)));
}

return res;
}



class Tbl_Erros
---------------


package entidades;


public class Tbl_Erros {

String Q3CODERRO;
String Q3DESCERRO;

public Tbl_Erros() {
}

public Tbl_Erros(String Q3CODERRO, String Q3DESCERRO) {

this.Q3CODERRO=Q3CODERRO;
this.Q3DESCERRO=Q3DESCERRO;

}

public String getQ3CODERRO() {
return Q3CODERRO;
}

public String getQ3DESCERRO() {
return Q3DESCERRO;
}
}

What should be the cause of this error?

yeah... maybe if you posted the error message we might have a clue.

Also post the line of code producing the error.
