Re: problem with getxml

[Flavio Palumbo]

Hi Joerg,

i found this strange behaviour :

the content of the fragment at /authentication/data/socOM in the context
authentication contains the code "8801", and i can see this value if i show
on screen with first snippet.

I thought that i could evaluate a variable in the same manner (second snippet)
; but this doesn't happen.

Anyway, looking at the mail archive, i found some interesting examples and
i wrote a little function that seems to work ; here is the code :

      private synchronized String getParAut(String inContext, String inPath)
{

         String sRet = null;
         org.apache.avalon.framework.component.ComponentManager cm = this.manager;
         org.apache.cocoon.webapps.session.SessionManager sm = null;

         //System.out.println("getParAut - cerco **"+inPath+"** in **"+inContext+"**");
         try {
             sm = 
(org.apache.cocoon.webapps.session.SessionManager)cm.lookup(org.apache.cocoon.webapps.session.SessionManager.ROLE);
             org.w3c.dom.DocumentFragment df = sm.getContextFragment(inContext,
inPath);
             StringBuffer sb = new StringBuffer();
             for (int i=0; i< df.getChildNodes().getLength(); i++) {
                  sb.append(df.getChildNodes().item(i).getNodeValue());
                  sRet = sb.toString();
             }
             if (sm != null) {
                 cm.release((Component)sm);
             }
         } catch (Throwable e) {
                 System.out.println("getParAut - Errore "+e);
         }
         finally {
                cm.release((Component)sm);
         }
         return sRet;
      }

           <xsp:logic>String sSoc = getParAut("authentication", 
"/authentication/data/socOM");</xsp:logic>
           <outEasy sizeFont="3" label="Codice Societa':" alignLabel="left"
widthLabel="100"
                     alignCampo="left" widthCampo="100" name="codiceSoc"
size="5">
                     <xsp:attribute 
name="value"><xsp:expr>sSoc</xsp:expr></xsp:attribute>

Please let me know what you think about.

Thanks a lot

Flavio

Not that I'm familiar with session:getxml, but what does "doesn't work"

mean?

Have

just text?

Try to put it not into an attribute, maybe that's the problem. You can
also have a look into the resulting Java code. Maybe there it is more
obvious.
