Hi Peter,

Yes, I believe you can do this (mostly) in EGL.

Although I don't know of a way to use purely EGL to get the file
information, I'm thinking that your service could make use of two or three
Java ExternalTypes in order to retrieve the "Last modified" attribute on the
file.

Using an ExternalType for the java.io.File class, and passing in the full
path to the file on the server, you should be able to instantiate the file
object through EGL and execute first its .exists() method, then, if true,
its .lastModified() method. This returns a BIGINT that we would need to
cast to a java.sql.Date, possibly, and maybe then to an EGL date. If it has
to be a timestamp, then we'd have to take a slightly different route.

Let me know if you want to pursue this approach and I'll try to help.

Best regards,
Ken

Subject: [EGL-i] Can this be done in EGL?

Hi Group,

I've been asked to look into a possible use of EGL as a web service in our
organization.

What we need is the following.

Our RPGLE application residing (of course) on the iSeries would call a web
service to check the timestamp of one or more files that reside on a windows
server (\\server\folder\file.ext<file:///\\server\folder\file.ext> paths
will be provided from the RPGLE). I would use HTTPAPI from Scott Klement,
of course.

The web service would then return the timestamps - if the files are found -
or a "no file" indication.

I already looked at some of the examples available in EGL café, but either
I'm not searching well, or there are no examples of EGL accessing or
retrieving information from files that have not been explicitly identified
in the project itself.

Any input would be highly appreciated, even if it is just "sorry, can't be
done in EGL".

Thanks in advance,
