Help with a TagExtraInfo class

[Lynna Cekova]

Hello!
I will be very thankful if you can help me with the following:
I need to create a TEI class to declare scripting variables for a tag that shows records from a recordset. The names of the variables, however, are the same as the column names in the recordset, so I don't know them in advance. Can anyone tell me how to declare the scription variables in the TEI class in case I don't know the names the Tag class will assign them?
Thanks,
Faerine

See if this example from weblogic helps you

  package weblogicx.jsp.tags;
import javax.servlet.jsp.tagext.*;
public class RepeatTagInfo extends TagExtraInfo
{
    public VariableInfo[] getVariableInfo(TagData tagdata)
    {
        String s = tagdata.getAttributeString("id");
        if(s == null)
        {
            throw new Error("TagLibrary inconsistency");
        } else
        {
            String s1 = tagdata.getAttributeString("type");
            VariableInfo variableinfo = new VariableInfo(s, s1 != null ? s1 : "java.lang.Object", true, 0);
            VariableInfo avariableinfo[] = {
                variableinfo
            };
            return avariableinfo;
        }
    }
    public boolean isValid(TagData tagdata)
    {
        return true;
    }
    public RepeatTagInfo()
    {
    }
}

-- iterate through the resultset
String st=new String(java.sql.ResultSet.getMetaData().getColumnName())

In JSP, you are not able to assign scripting variable names dynamically. The names of scripting variables need to be known at translation time, which is (potentially) long before any request is received.
