Oracle database connection by Java - timezone error


Error I got :

Error from db_connection.java -->> java.sql.SQLException: ORA-00604: error occurred at recursive SQL level 1
ORA-01882: timezone region  not found

ORA-00604: error occurred at recursive SQL level 1ORA-01882: timezone region  not found

Prev code:
    public Connection getOracle() throws Exception {
        Connection conn = null;
        Class.forName("oracle.jdbc.driver.OracleDriver");
        conn = DriverManager.getConnection("jdbc:oracle:thin:@127.0.0.1:1521:tap", "username", "pw");
        return conn;
   }



new Code:

    public Connection getOracle() throws Exception {
        TimeZone timeZone = TimeZone.getTimeZone("Asia/Kolkata");
        TimeZone.setDefault(timeZone);
        Connection conn = null;
        Class.forName("oracle.jdbc.driver.OracleDriver");
        conn = DriverManager.getConnection("jdbc:oracle:thin:@127.0.0.1:1521:tap", "username", "pw");
        return conn;
   }


now it is working!!

MDK Hospital opened in Horana

Image
Horana is getting a brand new private hospital! The M.D.K Healthcare Center & Hospital has just opened its doors on Anguruwathota Road, right next to the HNB bank branch. For years, many had to travel to Colombo for certain medical treatments, but hopes with new private hospital this will change. This new hospital, built by local businessman Mr. M.D. Piyananda Kularathna, comes with all the modern medical equipment we've been hoping for.

Disable single quote Within Forms

This is a good method taught to me by my friend to disable any character in the keyboard Within Forms in your web page/ web application.

My Docker learning short notes

I had this note from long time in my Evernotes, I thought I should have post it here, so someone might find it useful. This is just Docker basics and commonly used commands that I've collected over time. Why Docker? Docker enables containerization - running applications in containers instead of virtual machines. Important notes: Containers are not VMs - they have different benefits Provides standardization across environments Enables continuous deployment from development to production Ensures consistency using the same container image throughout the deployment process Key Benefits: Self-contained environments Isolated from other applications Runs almost everywhere (especially in the Cloud) Small and lightweight Highly scalable Fast deployment Core Concepts Images An image is an executable package containing everything needed to run an application: ...
