http://nagoya.apache.org/bugzilla/show_bug.cgi?id=10249 Tomcat hangs with Interclient JDBC driver Summary: Tomcat hangs with Interclient JDBC driver Product: Tomcat 4 Version: 4.0.4 Final Platform: PC OS/Version: Windows NT/2K Status: NEW Severity: Normal Priority: Other Component: Catalina AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] I have an environment with multiple virtual hosts. One of my users put an Interclient JDBC driver in his area and after trying to use it, Tomcat hangs. The curious is that 'connectionless' JSP pages work fine. Servlets and JSP pages that tries to connect to other databases, like MySQL, hangs too. I had top restart Tomcat. It might be a bug with JDBC2.0 or even in the driver, but I think Tomcat should be robust enough and harm other user's application. Steps to reproduce: - download the driver: http://www.kpi.com.au/interbase/files/interclient.jar ( you don't need to have Interbase server running anywhere !!) - servlet: import java.io.*; import java.sql.*; import javax.servlet.*; import javax.servlet.http.*; public class Interbase extends HttpServlet { public void doGet(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException { Connection con = null; Statement stmt = null; ResultSet rs = null; res.setContentType("text/html"); PrintWriter out = res.getWriter(); try { Class.forName("interbase.interclient.Driver"); Connection con = DriverManager.getConnection ("jdbc:interbase://localhost/data/mydb.gdb","SYSDBA","masterkey"); stmt = con.createStatement(); rs = stmt.executeQuery("SELECT * from users"); out.println("<HTML>"); out.println("<BODY>"); while (rs.next()) { out.println(rs.getString(1)); } rs.close(); con.close(); out.println("</BODY></HTML>"); } catch(ClassNotFoundException e) { out.println("ERROR " + e.getMessage()); } catch(SQLException e) { out.println("ERROR " + e.getMessage()); } finally { // Always close the database connection. try { if (con != null) con.close(); } catch (SQLException ignored) { } out.flush(); out.close(); } } } -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
