Yes. This would be definitely helpful. When I used lex/yacc their line
directives had me always pointing to the problem in my source.
When the logic sheets are matured, it's also unlikely, that the error
is in the logic sheet but not in your xsp.

I had a short look into this and there are two bugreports on this at Sun
which lead to a JSR. So this is definitely a problem, and having comments
in the generated code, which point me to the line and file the code
was generated from, would already help a lot.

Saxon has an extension function to retrieve the line
number of the context node (saxon:lineNumber()). Maybe
Xalan has an equivalent.

true... that's why I am not sure if it is really worth the work.
fact is: it will only really be useful if the error does not come from a
logicsheet. otherwise you would present code to the user/developer he
has probably never seen before. it might be easier to track things
though... I am really torn apart :-/

Some comments from XSP *users* would be fine...

hm.. you mean this way?

  ...
  
 int a = 5;
  
 
  
 b = a;
 c = x;
  
 ...

transform it once to add the line numbers. (it would be cool if the XSP
logicsheet could already provide this. but I fear that's not possible with
XSLT)
  ...
  
 /* line:4 */ int a = 5;
  
 
  
 /* line:8 */ b = a;
 /* line:9 */ c = x;
  
  

Then apply the logicsheets which might insert or remove lines from the
original code:

  ...
 /* line:4 */ int a = 5;

 .

 /* line:8 */ b = a;
 /* line:9 */ c = x;
  

Now the exception provides information about the final class line numbers.
We still would need to obtaint the information as described. but we could
then also parse the comment to get the original line number an present
that one in a nice exception. the malicious line highlighted with +/- 5
lines. if there is no line number in comments we know it was introduced by
a logicsheet and might not be very helpful to display this way.

But as I said... quite some hours of work...

question is: do people think this is helpful?

people? comments please...

Well now I have to go to the work directory and search the XSP. It would be
easy if I just can jump to the right line number...

I have thought about this a while ago, too. We should be able to extract
that from the exception stacktrace. It should also be even possible to
display that line's sourcecode (preferable with some surrounding lines).

But I wasn't sure if this is really worth the work...

Mmmh, probably won't work as it presumes that logicsheets behave well
which might not be true.

OK, that would make it easier to see the source (if I understand
correctly, that is). But I believe the original problem is infeasible
since we don't know what transformations happened on the way to the
final XSP (all taglibs but XSP done).

One could, of course, 
first run the XSP through a transformer that adds line number
   comments that are kept 'til the java file is generated, 

find the enclosing line number comments (well, one would suffice)

output the XSP with the line highlighted that translates to the
faulty java code

Would be kind of overhead outside development but then, a deployed
application wouldn't compile XSPs too often.

Chris.

well, addtionally we need the full classpath of the failed class itself
from the stacktrace. then we need to lookup the java source code filename
from the ProgrammGenerator. unfortunately that's not yet possible AFAICS.
but as a workaround we might translate back the class into a path and use
the workdir of the ProgrammGenerator as root, add the path and we should
have the generated file path from the repository...

What do you think?

Line number in Java source is already shown, correctly. The question is
how to map this to XSP source line numbers.

Great... 

when I code XSP and when I make some error in the logic I get (of course) an
error. An error contains a line number. Now I have to go to the work
directory and look at the generated java file to find the error. Isn't it
possible to display the line number of the error in the XSP?

Re: Problems with XSP

[cyril vidal]

I've put away the language attribute on the namespace.
So I have:

http://www.apache.org/1999/XSP/Core";>

static private int counter = 0;

private synchronized int count(){
return counter++;
}



 J'ai été visitée count() fois. 



but it still doesn't work...

Subject: Problems with XSP when upgrading 1.8.2 -> 2.0.2 

Forwarding this again, I think I sent to first one as HTML, which I
think the list doesn't recognize. 
 
I have looked in the mailing lists, to no avail, please forgive me if
these questions have been answered already 
  
I have upgraded Cocoon 1.8.2 to Cocoon 2.0.2. Here's my setup: 
  
Cocoon 2.0.2 
Weblogic 6.0sp2 
Solaris 2.6 (Sparc) 
  
I have successfully installed C2, all the samples work, etc. but I am
having a problem getting my logicsheets to work. I am having 2 separate
problems:
  
Problem 1: Transition from DOM to SAX 
In my logicsheets I have a number of places where I dynamically insert
an XML document, then use the DOM API to access values of specific
nodes. I have come to realize that since C2 uses SAX, I can no longer do
this. Here's an example:
  
String name = "Joe"; 
NodeList ca = document.getElementsByTagName( "employee" ); 
if ( ca != null ) { 
    Element element = null; 
    String myAttr = ""; 
    int length = ca.getLength(); 
    for (int j = 0; j < length; j++) { 
    element = (Element) ca.item(j); 
    myAttr = element.getAttribute( "name" ); 
    if ( !myAttr.equals( name ) ) continue; 
    myValue = element.getAttribute( "value" ); 
    break; 
    } 
} 
  
So if I have the following XML fragment: 
  
 
 
 
 
 
  
I want the value "45".  How would I do this with SAX? 
  
Problem 2: request and response using C2 specific implementation, rather
than javax.servlet.http.HttpRequest and javax.servlet.http.HttpResponse
I use some EJB's which have methods that take the built-in XSP variables
'request' and 'response' as params. It does not work now. Is there a way
to cast org.apache.cocoon.environment.Request as
javax.servlet.http.HttpRequest (and likewise for Response), or is there
a better way to do it? I would like to avoid having to modify the EJBs,
which at this point would be a Hurculean task.
  
Sorry if these don't seem to be Cocoon 2 questions, but I was thinking
maybe some of you have similar problems. 
  
Thanks in advance... 
  
William Bagby.

RE: problems with xsp date

[lisa . vangelder]

Thanks Jan, that worked.

I'm new to xsp as you've probably guessed!

Lisa,

first, java.util.Date is included, but java.util.Calendar isn't.
Try to include it by adding :
  
   java.util.Calendar
  

second, you should put your  block inside your  block

So, try this:

  
   java.util.Calendar
  

  
  Calendar now = Calendar.getInstance();
  now.setTime( new Date() );
  float hourAngle = (float) now.get( Calendar.HOUR   ) / 12 * 360; 
  float minAngle  = (float) now.get( Calendar.MINUTE ) / 60 * 360;

  hourAngle
minAngle


You can always check the Java code generated by the xsp, this sometimes
helps to understand the error.

Hi all

I'm trying to create a simple XSP page that gets the current hour and minute
and passes it on to a stylesheet. The cocoon docs say XSP automatically
generates import statements for the most commonly used Java libraries
(including java.util.Date).

However when I try run the page I get an error: Type expected.
now.setTime(new Date());

Has anybody got any ideas?

Here is the relevant part of the page:


   Calendar now = Calendar.getInstance();
now.setTime( new Date() );
float hourAngle = (float) now.get( Calendar.HOUR   ) / 12 * 360; 
float minAngle  = (float) now.get( Calendar.MINUTE ) / 60 * 360;
  



hourAngle
   minAngle



thanks in advance!

Lisa

Subject: problems with xsp date


Hi all

I'm trying to create a simple XSP page that gets the current hour and minute
and passes it on to a stylesheet. The cocoon docs say XSP automatically
generates import statements for the most commonly used Java libraries
(including java.util.Date).

However when I try run the page I get an error: Type expected.
now.setTime(new Date());

Has anybody got any ideas?

Here is the relevant part of the page:


   Calendar now = Calendar.getInstance();
now.setTime( new Date() );
float hourAngle = (float) now.get( Calendar.HOUR   ) / 12 * 360; 
float minAngle  = (float) now.get( Calendar.MINUTE ) / 60 * 360;
  



hourAngle
   minAngle



thanks in advance!

Lisa
