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?

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.

How to connect SQLite with Java?
(9 answers)
Closed 3 years ago.
My full project is on Github.com/DSkilton
I have tried dozens of ways to get this to work, I've read about classpaths, using Class.forName() and not using it, Xerials JDBC instructions which suggests using / rather than escaping \ for the path String. I've read through some of Oracles suggestions, Stackoverflow and SQlites tutorial on how to set up. I've really tried to research this but am still coming up blank!
Inside my src folder are the following folders: controller, images, lib, model, sample and view.
In the controller folder is databaseConnect.java and in the lib folder is jdbc-api-1.4.jar.
In my databaseConnect file I have the following:
public static void Connection() {
final String connectionUrl = "jdbc:sqlite:D:\\Users\\IdeaProject\\modus\\src\\model\\modus.db";
try {
Connection con = DriverManager.getConnection(connectionUrl);
System.out.println("Connected");
//while(returnStatement.next()) {
//System.out.println("rs.getString");
//}
} catch (SQLException e) {
e.printStackTrace();
}
The error I get is:
java.sql.SQLException: No suitable driver found for jdbc:sqlite:D:\\Users\\Duncan Skilton\\IdeaProject\\modus\\src\\model\\modus.db

Anything you can suggest will be massively appreciated!
You're missing Driver for your dbms. Add this to your pom.xml when using maven:
<dependency>
<groupId>org.xerial</groupId>
<artifactId>sqlite-jdbc</artifactId>
<version>3.25.2</version>
</dependency>
or this
implementation 'org.xerial:sqlite-jdbc:3.25.2'
to your build.gradle when using gradle.
P.S.:I don't think url is correct either. You don't pass the url to file on your drive, find some examples of urls for sqlite on the internet.
I am upgrading from Grails 2.4.4 to Grails 3.2.4.
I have setup a few factories to help me with testing, the role factory works fine, which runs before the users get created. Then I have the following code:
println "create user."
def testUser = new User(username: 'admin#mail.com', firstName: "admin", lastName: "admin", email: "email#mail.com")
println "User. :: " + testUser
println "User class. :: " + testUser.getClass().toString()
println("User Errors: " + testUser.errors)
testUser.save()
println "create user2."
def testUser2 = new User(username: 'trade#mail.com', email: 'trade#mail.com', firstName: "trade", lastName: "trade").save()
Of which the output is:
create user
User. :: Person: admin#mail.com
User class. :: class UserManage.User
User Errors: grails.validation.ValidationErrors: 0 errors

The save method fails, and it is not due to validation errors.
My class structure is APEntity as an abstract class and the User class inherits from the APEntity class. This code works fine in Grails 2.4.4
Any suggestions where I can look to fix the error would be greatly appreciated.
The class instance being constructed is User but the type seen is UserManage.User
at UserManage.User.save(User.groovy)
In my experience Grails 3 is much more type-safe than Grails 2 and less forgiving for ambiguity. Be explicit: User a = new User()
It turned out that validation was the problem.
After I ensured that the types were correct, I disabled all of my constraints. Once the constraints were turned off the validation problem became apparent. In my situation, it was that in Grails 2 I would simply input a null value for a date that is not specified. In grails 3 it seems that this is not allowed, I thus gave it a default value and the validation problem was fixed.
Just to add my notes on this topic since this was the post that made me put a lot of focus in the wrong aspects causing the issue, in the hope to save others spending time trying to identify something that doesn't seem correctly defined.
input a null value for a date that is not specified
This isn't strictly true.
I spent ages attempting to track where the issue was created a dummy site under 3.2.8 and tried to recreate the hasMany and actual objects that had nullable true. If this had been the case then a lot of additional work to fill in nulls where not needed and ultimately filling DB with stuff not required and breaking other logics of the code.
Either way so far as I understand this issue is caused in grails 3.2 by two things so far :
https://github.com/grails/grails-core/issues/10428
This was when a domain class object had
String aUser
static constraints = {
aUser(nullable:true)
}
The above is already fixed in later versions of 3.2.X
A new issue hit recently https://github.com/grails/grails-core/issues/10600 when a domain object has _underscore
String _user
static constraints = {
_user(nullable:true)
}
This appears to be in for fixing and should hopefully be fixed for 3.9
Meaning if you have _objects it will be safe to say it is likely to break under 3.2.X > - < 3.2.8 (was working in 3.1.10).
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.

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.
I used the following code to get IJavaProject type from string:
IProject project = ResourcesPlugin.getWorkspace().getRoot().getProject(projectName);
IJavaProject javaProject = JavaCore.create(project);
After this, I used javaProject.open(monitor); where monitor is of type IProgreeMonitor, to open the project... I am not able to open the filr there is some problem with it. The exception shown is:

As mentioned in my previous answer, your project does not exist, meaning you are trying to open 'null'.
Hence the exception.
I assume you mean IProgressMonitor.
IProgressMonitor is used to get updates on the progress of a task that is running in parallel (i.e. how near to completion it is), not to open resources.
I hope that explains the error, but I'm afraid I don't know how to open the project.
