Pb when calling the java task with a long line of arguments ?

[Olivier Prouvost <ol...@anyware-tech.com>]

Hi

I try to call xalan directly with the java task. (I know, I should use
the style task, but I need to call xalan1 or xalan2)...

Here is my taks :


<java fork="true" classpath="${myClasspath}" classname="${xalanClass}">
     <arg line="-TT -OUT ${OUT} -IN ${IN} -XSL
file://${wrapideXsl}/${XSL}  ${PARAM}"/>
</java>

In verbose mode, ant write this :

[java] Forking java -classpath ... org.apache.xalan.xslt.Process -TT
-OUT /home/olivier/GestionProjet.aad -IN
file:///home/olivier/GestionProjet.asd
-XSL file:///home/olivier/xslt/asd2aad.xsl -PARAM entity GestionProjet

But it does not work !   Whereas the generated command works well !!
(if I copy the generated command and execute it it works...)....

Is there a limitation for the line argument ? or a special encoding
generated ???

Thanks.

Ok I found it !!

Historically, my build file was wroking in the current directory
... basedir = '.'

Now, I use it from a static place, and I had to compute all the absolute
locations for my files... This is the reason why my parameter line was so
long... I gave the full path for IN and OUT parameters...

By setting the basedir parameter to my current directory, I don't need to
compute all my absolute paths... And my arg line is shorter... and it
works !!

In fact, it was, may be, a pbme with all the '/' in the line ? or may be
my absolutes paths were concat with the current basedir ?

I don't know...

Thanks for your help.

Nope. Not using fork should be the same except for CLASSPATH and
System.exit issues - and it doesn't involve a shell invocation where I
expect it to fail.

My Pbme is to call xalan1 or xalan2 according to some targets (in fact it
seems to be lots of differences between these 2 versions)... So I really
need to manage my own classpath when using xalan.

When I remove the fork attribute, I have the following error :

XSLT Error (javax.xml.transform.TransformerConfigurationException):
System property org.xml.sax.driver not specified

which is probably a pbme of classpath...

And I think, I need to set fork to true, because xalan seems to do a
System.exit which stop all processes of the current jvm !


In fact, I think that the parameters that are defined in the arg element
are passed to the java process and not to the class I call ? Is'nt it ?

Could be, as most OSs and/or shells impose a limit on command line
lengths. Can you get away without forking?
