Re: Xsp logic simpler error

Thanks to Luis Gois for answering

it now says:

"No method matching main() found in inner class org.apache.cocoon.www.pages.make1_xsp. make_xsl."

I really don't know why there is a space between make1_xsp. and make_xsl. Is it normal?

*******

Here is my code for make1.xsp

*******

<?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:structure>

<xsp:logic>
class make_xsl {
public void main(String[] args) throws IOException {
FileReader entree = new FileReader(("http//:localhost/cocoon/test/make.xsl"));
  FileWriter sortie = new FileWriter("output.txt");
int c;
while ( (c = entree.read()) != -1 )
sortie.write(c);
sortie.close();
entree.close();
     }
}
</xsp:logic>

<page>

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

If you see this, it works.
</page>
</xsp:page>

Surely I didn't put the anObject call at the right place. My java is rather experimental.

Thanks again.

Subject: Re : Xsp logic simpler error

You've made an inner class but you're calling it as a method!

Try this :

<xsp:logic>

make_xsl anObject = new make_xsl();

anObject.main();

</xsp:logic>

you main() method won't be called as you instatiate your make_xsl class, like it would happen if this was your program's starting/main class.
