mango can store data in mysql, derby or mssql database. derby can be setup as network instance so other programs can query.
while mango does use blobs to store some objects, you can cut and paste the code for turning the blob back into an object pretty easily.

if you want to write a JSP which displays some data for easy parsing look up the custom JSP function - I haven't done this so I don't know the specifics.

the data publisher surely must be adaptable to your needs?

modbus slave wouldn't help.

incoming http would work and I can write the jsp, but what do I query, I thought mango had a propitiatory data base?
