<p>I am trying to run an example from Pipelines Quick Start (p 24),
using the supplied file <font face="monospace">examples/calltest1.njp</font>.
But I am getting stuck right at the beginning.</p>
<div style="display:inline-block;white-space:pre;background-color:#012456;font-family:'Consolas',monospace;font-size:10pt;padding:4px;"><span style="color:#CCCCCC;background-color:#012456;">PS C:\Users\Jeff\documents\pipe tests> </span><span style="color:#F9F1A5;background-color:#012456;">pipc </span><span style="color:#CCCCCC;background-color:#012456;">calltest1
</span><div style="display:inline-block;white-space:pre;background-color:#012456;font-family:'Consolas',monospace;font-size:10pt;padding:4px;"><span style="color:#CCCCCC;background-color:#012456;">PS C:\Users\Jeff\documents\pipe tests> </span><span style="color:#F9F1A5;background-color:#012456;">java </span><span style="color:#CCCCCC;background-color:#012456;">calltest1
Error: Main method not found in class calltest1, please define the main method as:
public static void main(String[] args)
or a JavaFX application class must extend javafx.application.Application</span></div>
<span style="color:#CCCCCC;background-color:#012456;"></span></div>
<p>Here is the file <br>
</p>
<blockquote>
<p><font face="monospace">-- calltest1.njp<br>
<br>
pipe (callt1 debug 0 ) literal test | calltest1 10 | console<br>
<br>
import org.netrexx.njpipes.pipes.<br>
class calltest1 extends stage final<br>
<br>
method run() public<br>
<br>
say '1 .. 10, test'<br>
do<br>
a = arg()<br>
<br>
callpipe (cp1 debug 0 ) gen {a} | *out0:<br>
<br>
loop forever<br>
line = peekto()<br>
output(line)<br>
readto()<br>
end<br>
<br>
catch StageError<br>
rc = rc()<br>
end<br>
<br>
exit(rc*(rc<>12))<br>
</font></p>
</blockquote>
<p>I tried changing the top to:</p>
<blockquote>
<p><font face="monospace">-- calltest1.njp<br>
<br>
import org.netrexx.njpipes.pipes.<br>
class calltest1 extends stage final<br>
<br>
method main()<br>
pipe (callt1 debug 0 ) literal test | calltest1 10 | console</font></p>
</blockquote>
<p>but get the same error. I have also tried changing the file name
to <font face="monospace">calltest1.nrx</font> to no avail.</p>
<p>Anyone who can help would be greatly appreciated. (I have an
idea for a new stage that would allow a web browser to be the
output target of a stage like <font face="monospace">CONS</font>
-- that leads to all kinds of interesting things with fonts and
colors, etc --, but it needs to use <font face="monospace">callpipe</font>,
which I have never yet used.) <br>
</p>
<p>Thanks,</p>
<p>Jeff <br>
