Subject everything down
Date Sun, 23 Sep 2001 14:18:07 GMT
Hi,
In my attempts to write the output of an xsp to the disk,
my code makes Tomcat/4.0-b5 and Cocoon2b2 go completely down (every page is
404), the only message I get is in the dos window (nothing in log files):

CheckedIODemo: java.net.UnknownHostException: www.localhost

The only way is to restart Tomcat.
Here is my make2.xsp (mainly from Karl Øie in his answer in thread "RE:
Nobody Knows HOW TO SAVE STREAM ON DISK!!"):

<?xml version="1.0" encoding="ISO-8859-1"?>

<xsp:page
          language="java"
          xmlns:xsp="http://apache.org/xsp"
          xmlns:esql="http://apache.org/cocoon/SQL/v2">

<xsp:structure>
  <xsp:include>java.io.*</xsp:include>
  <xsp:include>java.net.*</xsp:include>
</xsp:structure>



<xsp:logic>



class make_xsl {
   public void main() {

try {
URL myurl = new URL( "http://www.localhost/cocoon/test/a1.html" );
BufferedInputStream inn = new BufferedInputStream(myurl.openStream());
BufferedWriter out = new BufferedWriter( new OutputStreamWriter( new
FileOutputStream("output2.txt") ) );
for(;;) {
     int data = inn.read();
if (data == -1) {
break;
}
else {
out.write((char) data);
}
}
out.flush();


       } catch (FileNotFoundException e) {
           System.err.println("CheckedIODemo: " + e);
           System.exit(-1);
       } catch (java.io.IOException e) {
           System.err.println("CheckedIODemo: " + e);
           System.exit(-1);
 } catch (NoSuchMethodError e) {
           System.err.println("CheckedIODemo: " + e);
           System.exit(-1);
 } catch (Exception e) {
           System.err.println("CheckedIODemo: " + e);
           System.exit(-1);
      }
 }
}

</xsp:logic>


  <page>
<xsp:logic>
    make_xsl anObject = new make_xsl();
    anObject.main();
</xsp:logic>


If you see this, it works.

My previous attempt (many thanks to Christian Haul) worked but only if the
input file (a1.html) was in Tomcat/bin directory , otherwise, everything
would get down, and  the only solution was to restart Tomcat:

class make_xsl {
   public void main() throws IOException {
 try {
 FileReader entree = new FileReader("a1.html");
  FileWriter sortie = new FileWriter("output.txt");
 int c;
 while ( (c = entree.read()) != -1 )
sortie.write(c);
sortie.close();
entree.close();
 } catch (FileNotFoundException e) {
           System.err.println("CheckedIODemo: " + e);
           System.exit(-1);
       } catch (java.io.IOException e) {
           System.err.println("CheckedIODemo: " + e);
           System.exit(-1);
       }

     }
}

Mario Muja also mentioned his interest in finding a way of saving output of
xsp on the disk.
Thanks to anyone helping us.
I'll maybe give this mail a try on tomcat users mailing list.
