I have a java application that will monitor stock prices and update a mysql database during the day. My code establishes the connection and will update/insert 1 record but on the next iteration it crashes and says the connection is closed. I need someone to access my computer through TeamViewer and fix this issue as well as help me with some sql related try/catch statements. Here is the error I am getting after the first iteration successfully inserts/updates the mysql database: Could not get mysql datasource:Data source is closed [login to view URL]: Data source is closed at [login to view URL]([login to view URL]) at [login to view URL]([login to view URL]) at [login to view URL]([login to view URL]) at [login to view URL]([login to view URL]) Exception in thread "main" [login to view URL] at [login to view URL]([login to view URL])

Hi I am a Java developer with over 5 years of experience and two of those are in the UK. Please refer to my profile for more information. If I could have a look at the code via TeamViewer, I could confirm whether I could solve the issue. It seems like an issue with the JDBC connection. If you are willing to share the source code or your screen via TeamViewer, please let me know in the chat. Kind regards, Saminda

Hi, I have over 6 years of experience in JAVA, J2EE, Spring, Hibernate. I am also having database related experience in MySQL, SQL Server, Oracle as well as MongoDB. I can solve your issue for sure. It would be better if you can give me your project and I can test it in my environment once. If your MySQL instance can be accessed over public network then that would be even better. Or else we can proceed over TeamViewer. Waiting for your reply. Thanks.
