Whe you try to create a Entity Class from DataBase and want to create a connection using MySQL 5.0 with conector/J 5.0, the IDE connects very well to the database but the wizard refuses to continue with thi following message "Unable to find driver", but there's already installed in the libraries secction of my proyect as well as in the appserver classpath. I'd tried with Derby and it works perfectly fine that.
Well just additional comments, the same project and classpath configurations (in a matter of fact, is the same appserver with the same configuration) worked well with RC1 and Betas, but with RC2 refuses to locate the driver, the workaround was to make a DB Schema and select it to make the Entity Classes from DataBase.
My office is effected by this issue too. We have to Macs running Tiger (and Netbeans 5.5 200610171010) that are effected. Interestingly, we have one Windows machine running the same NetBeans and it is able to find the driver in that dialog.
My partner happened to have 5.5rc2 still in his trashcan. He fired it up (version 200610160000, to be exact) and that version can successfully find the driver in this dialog. I'm not sure what's special about the Windows machine running 5.5 200610171010. That could be a clue to a workaround. Speaking of workarounds, does anybody have one?
Do you have the MySQL driver registered under Databases in the Runtime tab? If yes, which driver class is registered? (You can find that by right-clicking the driver and choosing Customize).
Yes, the driver is registered. The path to the jar is /Library/Java/Extensions/mysql-connector-java-5.0.3-bin.jar ...and the driver class is com.mysql.jdbc.Driver Netbeans is able to establish a connection to the database, too. It is only the "entity class from database" dialog that complains. For comparison, the Windows machine where this dialog works properly essentially has the same setup: C:\glassfish\domains\domain1\lib\ext\mysql-connector-java-5.0.3-bin.jar com.mysql.jdbc.Driver
I will try to provide a module with some logging, which might help me track down the cause of the issue.
It looks like to be an stopper in front of users who try to generate cmp from database. As it is one of Netbeans feature which users usually mention it shoulb be fixed sooner. I raise the priority to p2.
This is also the case in Netbeans IDE 6.0 Preview (M9).
I saw that sometimes, besides Netbeans uses com.mysql.jdbc.Driver for the "Runtime" tab Database connection, the DataSource sometimes uses the old driver org.gjt.mm.mysql.Driver, which no longer comes with the default driver jConnector 5, at leas NB seems not to find it. It's very funny, 'cause sometimes NB creates the DataSource with the correct driver and sometimes doesn't, how I figured this out?, well, when you select a DataSource form the "Create entity classes from database", and you click that dropdown list, and just put the cursor over the DataSource you wan't, it appears a popup message telling you the driver it uses, and there's where I found it, So this is a problem with the generation wizard of NetBeans.
Nitya, it seems this is yours.
Looks like the plugin's mapping of the sun resource's datasource-classname to driver info is the cause of error. Will fix. But this mapping will always have some deficiency. The IDE should ask for driver information if it is unable to resolve this or provide some way for the user to correct this instead of just popping up an error message.
Fixed for most cases by fix for IZ103161. Also fixed the original codepath which is now the fallback. IZ103161 adds a new codepath for most zero-config resource creation and reconstruction of url.

I am seeing this problem while trying to create entity classes for an AS/400 (IBM iSeries). I do have the driver registered, and I can see the table structure from the data source (in the Services tab). But when I try to create entity classes, I get "Unable to find the driver. Register this driver in the Databases tab[sic]." (My Postgres databases work OK.) I tried deleting and re-creating the driver reference under the Databases / Drivers node, and deleting the contents of var/cache in my userdir. NetBeans 6.0 FCS, IBM JTOpen 6.0 (JDBC driver). Is there a workaround? AS/400 data sources work OK with Swing apps and web apps that use JNDI data sources.
Could you please attach the sun-resources.xml from the setup folder of the project to help identify the issue. The plugin does not maintain mappings for the IBM JTOpen 6.0 (JDBC driver), so it might be better to open a seperate issue with respect to support for this driver. The original issue was filed with respect to MySQL
Opened issue 124212 for IBM JTOpen 6.0 (JDBC driver) support. Please attach the sun-resources.xml from the setup folder of the project in IZ 124212
Ignore previous comment. IZ 121601 was already opened for support for IBM AS/400 I have added gholmer to the cc of that issue. Marking this one as fixed for MySQL
