在使用GlassFish 4.1安装NetBeans 8.0.2之后，无法连接到示例数据库

Question

I installed NetBeans 8.0.2 with glassfish-4.1. The sample folder is present under C:\\Users\\Username.netbeans-derby. When I bring up NetBeans and go to the Services tab the connection to sample is present: jdbc:derby://localhost:1527/sample [app on APP] but sample is not listed under Java DB so when I try to connect to sample I get the following error "Unable to connect. Cannot establish a connection to jdbc:derby://localhost1527/sample using org.apache.derby.jdbc.ClientDriver (The connection was refused becuase the database sample was not found)."

Answer 1

Right click on Java DB select Create Database .

• use as Database Name 'sample'
• use as User Name 'app'
• leave the password empty

edit Seems there is a broken database or maybe one from an earlier Netbeans installation. Remove the sample connection in Netbeans and remove the directory %USERPROFILE%\\.netbeans-derby\\sample . Recreate the sample database as described above.

Answer 2

I had a broken database from an earlier version too, and then couldn't connect to the sample db. I simply had to delete the .netbeans-derby directory, then reinstalled Netbeans, and is was ok, then.

Answer 3

The same thing happened to me and re-installing NetBeans did not help. After poking around the databases for a bit, I finally got mine working using the following process.

1. Create a new database with any properties (ie name, user, pw)
2. Navigate to your user directory \\.netbeans-derby\\{name}\\
3. Copy service.properties file and paste in \\.netbeans-derby\\sample\\
4. Reconnect to sample database in NetBeans

A couple extra notes:

• If you configured your NetBeans database to a different location, use that location in step 2.
• You may need to delete and re-create the existing sample database connection in NetBeans for it to pickup the new service.properties file.
