The database was working fine, up until last week when disk ran out of space: Caused by: java.io.IOException: No space left on device at java.io.RandomAccessFile.writeBytes0(Native Method) at java.io.RandomAccessFile.writeBytes(RandomAccessFile.java:520) at java.io.RandomAccessFile.write(RandomAccessFile.java:550) at org.apache.derby.impl.store.raw.log.LogAccessFile.writeToLog(Unknown Source) at org.apache.derby.impl.store.raw.log.LogAccessFile.flushDirtyBuffers(Unknown Source) ...

Need to move the database and log files of JavaDB (derby) db files into deployment directories. The database is working in the application startup directory as JavaDB creates a folder with the name of the database (in my case mydb), but I want to move that dir into a subdir called data/ creating data/mydb. I can do this with the connect call: DriverManager.getConnection("jdbc:derby:data/mydb;create=false"); and this works. But I'd like to programmatically explicitly set the value of derby.system.home=data/ derby.stream.error.file=log/derby.log So I can do: DriverManager.getConnection("jdbc

After reading some tutorials and the course support, I have understood that I need to make a new data source under the Admin Console. So, I've logged in into the admin console, then navigated to Resources -> JDBC -> Data Sources -> New; filled in the fields and when I am testing the connection, the error I get is this one: Messages The test connection operation failed for data source MyDB on server server1 at node RO2CVG6CNode01 with the following exception: java.sql

For what type of requirements would you choose Apache Derby (or Java DB) over MySQL (or vice versa)? I looked around and people just compare the two but no one talks about when to consider each one. I am developing a web-based application using Glassfish + Java/Restlet + MySQL. I expect around 100-200 users for this system with a load of about 30-50 concurrent users at a given time - mostly. I was told to look at Derby if I wish to make the web-app downloadable/distributable. But is that the only reason why I would use it? Is it suitable for web-apps? Has anyone used it? What has been your

When I first connect to the data base it gives me the correct sequence next value with the following statement. VALUES (NEXT VALUE FOR :seqNm) But when restart my desktop application, there by reconnecting to the database, the next value gives me the next hundredth value. It seems like derby uses some caching for preallocating the sequence numbers. e.g. if my sequence starts with 100, First connection to the data base gives me sequences as 100, 101, 102 and so on. Second

I'm developing a Java desktop application and was really interested in use JavaFX. I'm planning to use an MVC architecture because I have had some experience with Java EE and the MVC model. I want to store data in a embedded derby database and use Hibernate as persistence layer but I can't find a great tutorial about implementing MVC with hibernate and JavaFX. I have created the persistence file but I am not sure how to make it work with JavaFX. In Java EE I inject EJB services or DAOs but since my app is not server connected I think I can't do that. Can someone explain me how to achieve that?
