[xmlblaster] Re: XmlBlaster and Firebird - last problem

[chris lau <ckl_88 at yahoo.ca>]

I finally got Firebird to work with xmlBlaster with no errors.

The blob issue (as described below) happened because the database mapping key in the
xmlblaster.properties file has to have a capital "F" as in "Firebird". You cannot have "firebird".
If it is incorrect, it will not find the correct jdbc mappings line and will then use the defaults
which uses "blob" as the blob variable name. If you know Firebird, "Blob" is a reserved word.


So entries in your properties file that refer to your database need to have a capital "F".
Oh, and the longint=decimal(18,0) needs to be enclosed in quotes as well like this:
Example:
JdbcDriver.mapping[Firebird]=string=VARCHAR(128),"longint=decimal(18,0)",int=integer,boolean=CHAR(1),blob=blob,blobVarName=msg

I'm not sure why this is. Probably because the JDBC driver returns Firebird and not firebird? 

I narrowed down the line in JdbcConnectionPool.java which returns the mappingKey to be:
mappingKey = conn.getMetaData().getDatabaseProductName();

Maybe in the future, somebody can modify the code so that it is not case sensitive. In other
words, convert the mappingKey to be uppercase using .toUpperCase() as to avoid these minor
problems.

If you need the complete properties file, please email me and I can send it to you.

Chris.
