If you want a component not to be "RMI" exported then you need to add
the attribute "sfRemote false;" to its description and then you don't
need to create its stubs.=20

In 1.5 it sometimes works because when the stubs are needed they are
generated on the fly.

Hi Julio and all,

I tried sth else: The temporary xsl file used for the transform was a
local "XmlFile" object in the method belonging to the "XmlFile" class
called by my component. There was no explicit filesystem where this
file could be dropped. Java 1.5 could handle the job keeping it
"virtual" but not java 1.4. So I split the component into 2: xsl
generation and then, transform and this way it works.

This is interesting. Under IntelliJ-IDEA there is a "package" onglet
in "project" panel, where they list all available libraries so I could
check all *_stub files were indeed there. However my components use
methods I defined in a public class ("XmlFile") which I did not make
remotely invocable. Is it the reason for all this? I set aside this
hypothesis because it worked under java 1.5. But if java 1.5 generates
stubs on the fly it changes the deal...

Here they are. Before line 2750 it's sfDeamon.

I tried this, too.

I came across this problem before: 'could not seal... package already
loaded' when I loaded the jars both in %PATH% and through the IDE
settings.

Thanks a lot,
