I'm reposting to fix the typo "public void setgetErrdesc...". text below is
corrected. I'm still having the same parsing problem as before.
You know, if I reformat the XML string to look like this:
<loginerr errnum="18" errdesc=" Your smallcorp site login has expired!!"
/>
...it works fine (I can create my bean using the digester).
The question is why doesn't work for the XML formatted as:
<loginerr>
<errnum>18</errnum>
<errdesc>Your smallcorp site login has expired!!</errdesc>
</loginerr>
Aren't both xml formats correct? Are these Digester peculiarities, or SAX?
I have tons of XML I need to parse that have this latter format and am
desperate to make this work!!
Thanks, Paula Young

Subject: Digester help needed !
I need some basic DIGESTER help! I think I'm trying to do
something simple, but it's not working for me and I've tried several things,
etc,etc,etc... I just want to parse an XML string that looks like:
<loginerr>
<errnum>18</errnum>
<errdesc>Your smallcorp site login has expired!!</errdesc>
</loginerr>
My ErrResp.java bean that should result in the parse looks
like:
package com.oaktree.struts.common;
import java.io.Serializable;
public class ErrResp implements Serializable {
private int errnum = 0;
private String errdesc = null;
// -- integer code for the error
public int getErrnum() {
return errnum;
}
public void setErrnum(int errnum) {
this.errnum = errnum;
}
// -- description of error
public String getErrdesc() {
return errdesc;
}
public void setErrdesc(String errdesc) {
this.errdesc = errdesc;
}
// -- Utils
public String toString() {
StringBuffer sb = new StringBuffer("ErrResp is:\n");
sb.append("Errnum=" + errnum + ".\n");
sb.append("Errdesc=" + errdesc + ".\n");
return sb.toString();
}
}
AND my code (in the LoginAction.java ) looks like:
// simulate XML string return for an error.
StringBuffer xmlerr = new StringBuffer("");
xmlerr.append("<loginerr>\n");
xmlerr.append("<errnum>18</errnum>\n");
xmlerr.append("<errdesc>Your smallcorp site login has
expired!!</errdesc>\n");
xmlerr.append("</loginerr>\n");
// Use Apache digester util to parse that xml string.
// LoginResp bean : it contains: Away, Buddy, Group
beans
String xrsp = xmlerr.toString();
System.out.println("XML is:\n" + xrsp);
Digester digester = new Digester();
digester.push(this);
digester.setDebug(10);
digester.setValidating(false);
digester.addObjectCreate("loginerr",
"com.oaktree.struts.common.ErrResp");
digester.addSetProperties("loginerr");
digester.addSetNext("loginerr", "gotErr",
"com.oaktree.struts.common.ErrResp");
try {
digester.parse(new org.xml.sax.InputSource(new
StringReader(xrsp)));
} catch (IOException e){
e.printStackTrace();
} catch (SAXException e) {
e.printStackTrace();
}
The 'gotErr ' that's referred to above is in the
LoginAction.java class and is simply:
// Method called after parsing a Loginerr XML Response:
public void gotErr(ErrResp er)
{
System.out.println("ErrResp bean:\n" +
er.toString());
}
When it runs, the debug output I see in my window is:
New com.oaktree.struts.common.ErrResp
Set com.oaktree.struts.common.ErrResp properties
Call com.oaktree.struts.logon.LogonAction.gotErr(ErrResp is:
Errnum=0.
Errdesc=null.
)
ErrResp bean:
ErrResp is:
Errnum=0.
Errdesc=null.
Pop com.oaktree.struts.common.ErrResp
... I see the ErrResp object gets created, then properties
set, but when gotErr is called, the bean is empty. I'm not understanding
why this straightforward case isn't working! Otherwise, I think the
Digester utility is pretty slick, and I'd also be interested in the
reverse-digester utility, if any, question in "tiles / portal / digester"
message subject post.
