    text
    copied!<p>I am trying to connect my tomcat servers to a MS SQL 2008 R2 server. Network connectivity is not the issue here.</p> <p>I can successfully connect in a simple java app, but when I try to connect via tomcat7 (tried on my Windows 7 workstation as well as my Ubuntu 12.04 server.</p> <p>I am able to run the example servlets on both tomcat servers.</p> <p>My code:</p> <pre><code> public class DBConnector{` private java.sql.Connection con = null;` private final String url = "jdbc:sqlserver://my.domain.com:";` </code></pre> <p>//PORT NUMBER, CREDENTIALS, ETC. These all work in standard java app.</p> <pre><code>public DBConnector(){} private String getConnectionUrl(){ return url+ portNumber +";databaseName="+databaseName+";selectMethod="+selectMethod+";"; } private java.sql.Connection getConnection(){ try{ Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver"); con = java.sql.DriverManager.getConnection(getConnectionUrl(),userName,password); if(con!=null) System.out.println(getConnectionUrl()); }catch(Exception e){ e.printStackTrace(); System.out.println("Error Trace in getConnection() : " + e.getMessage()); } return con; } public void queryDB(){ try{ System.out.println("Connecting..."); con= this.getConnection(); if(con!=null){ System.out.println("NotNull"); java.sql.Statement statement = con.createStatement(); String query="Select * from CAFE"; java.sql.ResultSet rs = null; System.out.println("made rs"); rs = statement.executeQuery(query); System.out.println("Established what it is"); java.sql.ResultSetMetaData rsmd = rs.getMetaData(); System.out.println("Getting MetaData");` //Omitted the rest. </code></pre> <p>It stops responding in tomcat at: rs = statement.executeQuery(query); because on the console, I never see "Established what it is".</p> <p>I am using the correct mssql driver version for Java 6.</p> <p>I am very new to this so quite likely made an obvious mistake here. Any suggestions?</p>
