Andreas Schaefer's BlogRE: File Access in EJBPosted by schaefa on October 09, 2003 at 12:50 PM | Comments (2)As Simon Brown pointed out the J2EE specification restrict you to access files on the file system but sometimes you have to and then you need to control the damage by keeping the breach of the specification local and not to spread it all over your code. Being confronted with this question just recently I came up with these ‘solutions’:
First I was thinking that only a file service (like JDBC or JMS) provided by the server could solve the problem. But after thinking it through using Entity Beans seems to be a much better way to share the data on a cluster than through a file service. Then I realized that maybe each deployed EJB needs to have its own file that is not shared on the cluster. I think it is very important for each J2EE developer to see that there is much more between heaven and earth that a specification can ever capture. But it is important for the future of the code/project that ‘unportable code’ is kept localized and under control and that the assumptions and restrictions of that code is documented well.
