Valentina SQLite Server is one of three servers in Valentina Server.
Java sqlite code#
The source code for SQLite is in the public domain. SQLite is an in-process library that implements a self-contained, server-less, zero-configuration, transactional SQL database engine. SQLite is an incredibly popular single connection, local database because it provides a stable, flat-file database solution for application developers.
Java sqlite full#
Import SQLite Server is a full featured, standards compliant multi-user access SQLite based database server. This is my web project structure which idea creates in \out directory.Īnd Servlet class that handles index page.
Should I change something in that jar? I have no idea why sqlite3 in tomcat tries to access this /temp/. I can change it via command line, but Tomcat uses sqlite3 jar library to open my database. In SQLite documentation I found a variable to tell sqlite whether to use temp folder or memory. But if I catch (Throwable), then I have a log file record - that means an Error is thrown. I am sure tomcat load sqlite3 jar library because we have exception thrown from package.Īlthough I am confused why I have no record in my log file from this getRooms() method if I catch any Exception. I am sure tomcat finds that rooms.db file because if I change path - I get SQLException and a "Can't get connection. Or I tried adding Context tag into GlobalNamingResources tag in tomcat-dir/conf/server.xml - which is not recommended, I know, but still no result. I also tried instead creating context.xml with the same Context tag into /META-INF/context.xml with the same code. Where testProject_war_exploded is the name of my app. In order for Tomcat to find my database I created resource-ref in web.xml Īnd also added Context tag into tomcat-dir\conf\Catalina\localhost\testProject_war_exploded.xml (room.getName() + " " + room.getCountr圜ode() + " " + room.isLightOn()) Private final String connectionString = "jdbc:sqlite:rooms.db" Ĭonnection = DriverManager.getConnection(connectionString) So it makes me think it's completely on "tomcat side" import model.Room However this code I used for SQLite access check without Tomcat works fine. Precisely this row is written in Servlet's exception as : (DAO.java:28) connection = ds.getConnection()
Log.debug("SQL Exception thrown during select statement") Log.debug(room.getName() + " " + room.getCountr圜ode() + "" + room.isLightOn()) tCountr圜ode(rs.getString("country_code")) ResultSet rs = statement.executeQuery(sql) Statement statement = connection.createStatement() Log.debug("Can't get Context or Datasource") Private final String driverName = "" ĭataSource ds = (DataSource)ctx.lookup("java:comp/env/jdbc/rooms")
Private final Logger log = Logger.getLogger(this.getClass()) This is the method which throws an exception: package model Skipping unneeded JARs during scanning can improve startup time and JSP compilation time.Ġ 21:11:38.375 INFO .StandardContext.reload Reloading Context with name is completedĬ:\Dropbox\apache-tomcat-9.0.22\temp\sqlite-3.21.0. (Системе не удается найти указанный путь) Enable debug logging for this logger for a complete list of JARs that were scanned but no TLDs were found in them. In a tomcat's startup.bat command line window I see this: 0 21:11:37.875 INFO .StandardContext.reload Reloading Context with name has startedĠ 21:11:38.352 INFO .TldScanner.scanJars At least one JAR was scanned for TLDs yet contained no TLDs. Note The full stack trace of the root cause is available in the server logs. Message Servlet execution threw an exceptionĭescription The server encountered an unexpected condition that prevented it from fulfilling the request.
I also can access SQLite database via JDBC as a plain JavaSE application when I run it in intellij idea: screenshot.īut when I start my web project on Tomcat, on the web page ServletException is thrown cased by UnsatisfiedLinkError: HTTP Status 500 – Internal Server Error I can access SQLite database directly (using command line and sqlite3 downloaded library: screenshot). I use SQLite3 database, develop in IntelliJ Idea IDE, compile project with Maven and test in Tomcat 9.0. I'm developing web Java application with Servlet, JSP, JSTL technologies.
