I'm using Java version 8 update 261. I know that PDI requires Java 8 so I don't understand why I'm having this issue. Currently, I have to delete and then create a new database connection for each job, which is really tedious.
How do I resolve this issue? Or is there another way to set my database connections so that I don't have to create a new one for each job?

I don't know about your error message, but to share connections IN YOUR PC you have the option in the View tab:
I have an empty transformation, so all the DB connections shown are the shared ones, if I had a new connection in the transformation it would be also shown but the connection name wouldn't be in bold letters.
Beware, the shared connections information are only available in your PC, and the connection information is copied to the transformation or job, so if you change the information in your shared connection, you need to reopen all the transformations and jobs that use it and save them with the new information.
In the .kettle folder in your user folder there's a shared.xml file with the shared connections information.

Disable "Detached"-Action in SWT - "Wrong parent"-Exception

Im working in a project, with a Eclipse SWT-Application. On the tabs of all views there are the default-actions, for example the "Detached"-Action that takes the tab and creates a detached window for it.
In our case, this leads to the following exception:
Widget has the wrong parent
java.lang.IllegalArgumentException: Widget has the wrong parent

I know that there is a constant called ENABLE_DETACHED_VIEWSin IWorkbenchPreferenceConstants and that the default value of which is true.
I now try to disable the "Detached"-Action in general (also hints how to disable it in one view would be appreciated). Is there a way I can override the default-value of said constant, or any other way of removing the "Detached"-action from the rightclick menu on my tabs?
Thanks for your help
EDIT:
We're working with SWT 3.6

Ok I found it out myself. As far as I found out you have to extend WorkbenchAdvisor.
In this subclass you have to override createWorkbenchWindowAdvisor in which you can override the IWorkbenchPreferenceConstants like this:
#Override
public WorkbenchWindowAdvisor createWorkbenchWindowAdvisor(IWorkbenchWindowConfigurer configurer) {
PlatformUI.getPreferenceStore().setValue(IWorkbenchPreferenceConstants.ENABLE_DETACHED_VIEWS, false);
return new ApplicationWorkbenchWindowAdvisor(configurer);
}
This will prevent the application from detaching any views and also remove the right-click action "Detached".
Be aware that (from what I found out) this solution will only work in version 3.X

Eclipse IDE doesn't recognize mysql driver

This has been extremely frustrating, especially since I've been all over the forums and have followed all the directions, as far as I can tell.
I am trying to create a connection to a local mysql database. First I downloaded the mysql driver from http://dev.mysql.com/downloads/connector/j using the platform independent TAR (I'm on ubuntu). Then I placed the resultant JAR into a new folder I created for my project call /lib, and then right-clicked and selected "Add to Build Path". It now shows up as a Referenced Library.
For the code, I am doing the typical things you would do:
try {
Class.forName("com.mysql.jdbc.Driver");
String db_url = "jdbc:mysql://localhost/project";
connect = DriverManager.getConnection(db_url, "user", "password");
statement = connect.createStatement();
resultSet = statement.executeQuery("select * from database.table");
while (resultSet.next()) {
int id = resultSet.getInt("ID");
String name = resultSet.getString("Name");
System.out.println("(ID: " + id + ") (Name: " + name + ")");
}
} catch (ClassNotFoundException | SQLException e) {
e.printStackTrace();
}
But for whatever reason, I still get "java.lang.ClassNotFoundException: com.mysql.jdbc.Driver cannot be found"
I'm sure it's something completely idiotic on my part, but any pointers as to what I'm missing?
Here is the stack trace:

So I probably didn't explain my problem well enough before. The question specifically related to getting my Eclipse RCP application to see the driver. After talking to a friend he reminded me that I needed to add the mysql jar to the .MF file directly. Once I knew that I found a ton of posts on various forums answering my question.
I added the following line and I'm able to make the connection to the database without issue:
"Bundle-ClassPath: lib/mysql-connector-java-5.1.30-bin.jar, ."
The (.) at the end also was very important and stymied me for a few minutes.

I just made a quick copy / paste of your code into a fresh project, installed the driver in lib... works like a charm. So did you do something before the code snippet?

birt won't save data set, "the structure is invalid" error

We're trying to update a BIRT report project after recreating a database. So I type the new query but when I move to the Parameters tab (or any tab), the error:
The structure is floating, and its handler is invalid!
pops up, and in the error log the following error is shown:
Problems occurred when invoking code from plug-in: "org.eclipse.jface".
Then after that nothing else works; the changes don't register (there's no asterisk near the library name in the tab), and I can't save anything.
Stack trace:

I don't know what to search; all results I've come upon come from different errors. Starting with "-clean" doesn't work, recreating the BIRT report project doesn't work... Any nudge in the right direction would be help enough.
Regards,
Cez

I got the same error, but performing below steps helped me out.(I am working on a table )
Delete the data sets
Select the table, under property editor tab, click on binding tab, check Data set and select none.
You should get a prompt asking if you wish to clear all existing data feild information, Click on 'yes'.
All the data bindings with references to the deleted data sets will now be cleared and voila... continue with your work. Let me know if this worked for you too.

Any guesses why?

Got it, the WSDL is very big, so the sub creation timed out, here is the solution:
Disable the timeout in Windows>Preferences>Web Services>Axis Emitter>Timeouts in Second = -1

While setting the timeout to -1 (i.e. infinite or no timeout) would solve the timeout problem, it could pose a risk of having a hung eclipse workbench in a worst case scenario. Setting it to a high enough value (e.g. 600) should be a safer alternative.
