Hi,

I am using Ilog's JRules which is a rule engine. It also allows to save files(known as repositories) to a database. I am wrting a tool that does a back up and restore of these files.

BackUp Logic - Read from database, put data in tablewise Vectors and serialize to a file.

Restore Logic - Read from the .ser file and write the data to the database.

The backup and restore works fine only until opening the restored repository in ILog. When i open the repository in ILog it gives me

org.xml.sax.SAXParseException: Content is not allowed in prolog exception. I guess its probably not able to parse the data that is retrieved from the database, may be encountering an unwanted caharacter. Has it got to do anything with the encoding? Please suggest.

Regards,

Nikhil

It sounds like you've got something illegal in the beginning of your XML document (before the root element's beginning tag).

Anyway, I'm moving this topic to theXML forum since it's more about XML than XML Certification.

Hi,

That error does not occur anymore. Actually the Informix JDBC driver blew up in the executeBatch() method. It persists the first value in the batch for all the rest of records in the batch. Well now I am encoutering a different problem. I still cannot open the repository in ILog. It gives me a java.util.zip.ZipException: invalid block type
at java.util.zip.InflaterInputStream.read(Unknown Source).
Unfortunately, I have no clue of how ILog reads the repositories from the database. Any help will be appreciated.

Regards,

Nikhil
