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 Řie 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.

</xsp:page>
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.
