    <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>

    1. COWhat do you mean by stops responding? Does it sit there forever or does it actually throw an exception? If it throws and exception, what actual exception does it throw?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
