Actions performed for jbuttons
I have a grasp pretty much on where to and how edit the code via netbeans. The tutorial on the netbeans website has been helpful. However, it has only explained to me how to make a button exit, clear, or add. Is there a list of actions that can be performed or is that something i’d have to figure out.

Let me know if it throws nullpointerexception in any case ? If it throws how to handle this ?
Is it possible to disable SSL certificate checking in the amazon kinesis consumer library v2?
When developing a Kinesis Consumer using Version 2 of the Kinesis Consumer Library and overriding the Dynamo DB endpoint to a localstack endpoint the library fails to create the leasing table due to SSL handshake errors.
I can confirm that creating the table succeeds when using AWS' Dynamo DB, but as soon as I override the endpoint url to a localstack url the Dynamo DB client fails to create the lease table after multiple retries. The stack trace isn't that useful but Wireshark shows all of the SSL handshake errors so I can only assume the Amazon SDK is not accepting the localstack certificate. I cannot find any mention of how to disable certificate verification using the
Region region = Region.of("us-east-1"); DefaultCredentialsProvider credentialsProvider = DefaultCredentialsProvider.create(); DynamoDbAsyncClient dynamoClient = DynamoDbAsyncClient.builder() .region(region) .endpointOverride(URI.create("https://localhost:4569")) .credentialsProvider(credentialsProvider) .build();
/edit This is based off the example from Amazon found here: https://docs.aws.amazon.com/streams/latest/dev/kcl2-standard-consumer-java-example.html
Problem creating an OracleDataSource correctly from tomcat context.xml
In the project im working at the following problem occurs:
We use Database connections defined in our tomcat context.xml. For now this has worked without problems.
<Resource auth="Container" driverClassName="oracle.jdbc.driver.OracleDriver" logAbandoned="true" maxIdle="10" maxTotal="100" maxWaitMillis="5000" name="NAME" password="PASSWORD" removeAbandonedOnMaintenance="true" removeAbandonedTimeout="60" type="javax.sql.DataSource" url="URL" username="USERNAME" />
This type of resource definition is used in the webapp for every database connection, retreiving the datasource like this:
InitialContext ctx = new InitialContext(); DataSource dsAux = (DataSource) ctx.lookup(dbCon);
The problem begins here. Oracle queues are being used with jms (Java Message System) for a lot of processes. For this, as it is coded right now, we need an OracleDataSource that can be created having only the db url, password and username.
My question is, is it possible in any way or form to get all the data needed from the context for this type of datasource correctly? I have tried changing the datasource type without any luck, unwrapping the already created datasource to try and create an OracleDataSource, in the end, the only possible solution I have come up with is to change how database connections are saved.
