How To Connect Two Applications To One Table In Java
Aug 25, 2013
I am working on a hospital application using java programming language, i need to know how to connect two applications to one table over a network where the data read by application one can not be read by application 2 and vise versa...
I designed the AlwaysOn wrong, but every time we fail over from primary server to another server, my applications cannot connect because the sql logins cannot connect to their default databases. Once I run the command to link the login with the user in the default database then the users are able to connect. Did I do something wrong when designing AlwaysOn?
I'm having a problem connecting with a Java application but I CAN connect using my .Net application - the user name and password are the same for both (using the same database on SQL Server Express 2005).
The error I get is: "com.microsoft.sqlserver.jdbc.SQLServerException: Cannot open database "CORNERS" requested by the login. The login failed." An interesing note - I get the same message if the database is not running.
SQL Server Express 2005 is installed in mixed mode.
Here is my connection string in the .Net appplication: <add key="connectString" value="Server=(local);UID=sa;PWD=myPasswd;Database=CORNERS" />.
I am using ASP.NET 2.0 login control. this control connect to ASPNET.MDF database. I built another application using windows service, and this application also connects to ASPNET.MDF database. problem is that the first application that connects to the database, locks the database, and so the other application cannot use the database untill the other application is closed. I am going on circles about this, and just don't know what to do. Please please please. love me do.

I use the code below to connect to my oracle database... but now i want to use java code to connect to mdf database file...
Is there a way to do it? What will be the connection string in that case? Thanking you in advance..
/* THIS CODE Connects to oracle database using java language*/ Connection con = null; Statement st =null; Statement batchStm = null; System.setProperty("jdbc.drivers","sun.jdbc.odbc.JdbcOdbcDriver");
System.out.println("Registred Driver");
//Conecting to dbase con = DriverManager.getConnection("jdbcdbcbSourceOra","scott","tiger");
Hi, guys. It's the first time I connect a database.
My OS is windows XP.
I downloaded the sqljdbc on microsoft website and unzipped it. Copy the sqljdbc_1.1 to the directory C:Program Files.
Modified the system variables: classpath=.;%JAVA_HOME%libdt.jar;%JAVA_HOME%lib ools.jar; %ProgramFiles%sqljdbc_1.1chssqljdbc.jar JAVA_HOME=D:Program FilesJavajdk1.5.0_10 ProgramFiles=C:Program Files
I installed the sqlserver 2005and created a sqlserver db engine with windows authentification by default.
Using the management studio I created a database named BudgetAuthorization. After that I created a user: CREATE LOGIN aaron792 WITH PASSWORD='12345' USE BudgetAuthorization CREATE USER aaron792
Now I want to write a java application to access the database. The application and the database are on the same computer.
I started the TCP/IP service, using the configuration manager.
Then use the eclipse to write the java application:
import java.sql.*; public class TestJDBC { public static void main(String[] srg) { String driverName = "com.microsoft.sqlserver.jdbc.SQLServerDriver"; // Start JDBC String dbURL = "jdbcqlserver://localhost:1433; DatabaseName=BudgetAuthorization"; // Connect the server and the database //String userName = "Administrator"; // windows user //String userPwd = "password"; // windows login password String userName="aaron792"; String userPwd="12345"; Connection dbConn; try { Class.forName(driverName); dbConn = DriverManager.getConnection(dbURL,userName,userPwd); System.out.println("Connection Successful!"); // if successful print Connection Successful! } catch (Exception e) { e.printStackTrace(); } } }
But it cann't be done! The error information is: Login failed for user 'aaron792'. The user is not associated with a trusted SQL Server connection.
I also tried the windows user, still failed. What's wrong? Can anyone help? Many thanks!
Can applications connect to SSAS Tabular mode cubes through ODBC drivers? I have been asked the question specifically regarding SAS, and I can see (for example) SAS Enterprise Guide has the ability to connect to sources via ODBC, so I now need to find out if there are such things as ODBC divers for SSAS (specifically Tabular).
The TCP/IP connection to the host has failed. java.net.ConnectException: Connection timed out: connect" whenever i try to connect to the remote DB which is present at a different system.
I am new to connecting to databases through java and in fact have not done much database programming although I am fairly good at SQL. I have used the MS JDBC driver to connect to a MS SQL server database but I want to update my application every time a record is added to the database and or alert the user. From what I have read, i assume that I can create a Trigger in java but how do I get my trigger to call a method / run java code?
Hello,I am writing an application using Visual Studio .NET (C#). Theapplication will be run on several workstations simultaneously, andall of them will be accessing a single sql server database. I amtrying to have it so that when one of the applications updates thefields of a table in the database, all of the other applications arenotified (Without polling the DB).I have been trying to do this by using a SQL Trigger and callingRaisError from within. This will create an exception for the callingapplication (what i wanted), but I can get any of the otherapplications to see the error.Is there a way of accomplishing this using triggers? Is there anotherway of notifying all applications of a database change without the useof polling?James ChangJoin Bytes!
My preferred programming language is Java (sorry Microsoft). I've searched for examples of running DMX queries into an Analysis Services database from Java but failed to locate any. I've seen suggestions that XMLA could be used but again, I can't locate any examples (in any language). For my current project I ran up the white flag and used C# instead but this wouldn't be an option in other cases. It would be possible to make the DMX calls from C# objects and call those from Java but that's pretty labourious to code.
Anyone have any tips for using Java against SQL Server? Our ITdirector is thinking of making us a Java shop, but I really would liketo stay with SQL Server as our RDBMS. We have Oracle Financials butour in-house development (currently VB6 client-server, soon to bereplaced by a service-oriented architecture based around Sonic andincluding SalesForce, both of which are Java) has been against SQLServer. He says five years ago at his old company Java/SQL Server hadlousy performance. I vaguely remember that since then Microsoft cameout with their own JDBC driver for SQL Server... Anyone have experiencewith this? Any performance tips will be hugely appreciated.TIA
hi all and sorry for my englishI write into a SqlServer2000 database via jdbc using a PreparedStatement(pstmt) and one of fields is a TimeStamp, my code is:qwdum=System.currentTimeMillis();pstmt.setTimestamp(8 , new Timestamp(qwdum));sometimes the field on table is correct (the milliseconds are the same oflast 3 digits of variable qwdum), other times it has a difference of 1 o 2millisecondsthe same code with jdbc Oracle or iSeries works fineany idea?thanksRoberto Nenni
I am in the process of evalulating using SSRS with our Java app and I have a couple questions up front:
I see you can call SSRS thru web services and display an HTML report. Can you have the report go straight to the printer, rather then preview. So we can offer both Print and Print Preview options.
I see the page streaming option. So on page preview we could ask for page 1 to get a snappy display, then ask for the rest of the report to generate in background?
i want to use the sql server with java, but i don't find any documentation. I already loaded the sqljdbc.jar from the microsoft webpage, but i don't know how to connect.
This is my Connection function, but it doesn't connect. I get an exception like "cannot connect to ..."

I have a SQLexpress db that i would like to be able to access from both a windows app and web app (both running on the same machine) at the same time. Is this possible. I've been able to connect either one or the other, but not both at the same time. Thanks
If there are 2 different web application connecting to a sql server database through ODBC connection, both of them have full privilege to update , create , add column etc. Would there any issues of SQL server impacts when actually on live.
Hi to all.. Does anyone know about some useful resources of programming Accounting and General Ledger applications..SQL scripts,books..etc. Thanks to all..
I am running SQL Server 2005 Dev x86 with SSRS SP1 on Windows2003 Svr SP1.
My SQL Server is running and SSRS is working. When I come to run certain installs though, my Server name is not present in the dropdowns or in the browse for installed server lists.
I entered the name of my SQL server manually, but when I ran the application, it gave me an error: 00250 unable to run dtabase locator service.
i am a computer sciences engineering student and and we have an assignment to create a web project with a database.
Our lecturers will store our submissions on a db server but they want our projects enable the restoring our own databases..
that is, they wanna be able to have a copy of our databases to a new db that they have just created.. and they want us to enable this feature in an install.aspx page in our project.. the new db is guaranteed that will have the same name as ours..
so now what i am supposed to include in install.aspx?

I'm having a problem getting back appropriate metadata for storedprocedures from MS SQL Server 2000 and 2005.I've created a simple stored procedure that has an output param thatis a cursor.When I ask for the metadata for that stored procedure using a JDBCdriver I get back a datatype value for my parameter specifying an intnot a result set.Here is my stored procedure:CREATE PROCEDURE xasp_INx_OUTcur_RETint@OutCrsr CURSOR VARYING OUTPUT ASSET @OutCrsr = CURSOR FORSELECT LASTNAME, FIRSTNAMEFROM CONTACTS2OPEN @OutCrsrRETURN 7Here is the java code:Connection conn = driver.connect(url, props);DatabaseMetaData dbMeta = conn.getMetaData();ResultSet columnRes = dbMeta.getProcedureColumns(cat, schem, name,"%");while (columnRes.next()){String procCat = columnRes.getString("PROCEDURE_CAT");String procSchem = columnRes.getString("PROCEDURE_SCHEM");String procName = columnRes.getString("PROCEDURE_NAME");String colName = columnRes.getString("COLUMN_NAME");short colType = columnRes.getShort("COLUMN_TYPE");short dataType = columnRes.getShort("DATA_TYPE");String typeName = columnRes.getString("TYPE_NAME");int precision = columnRes.getInt("PRECISION");// pass this info on to another method}The dataType is set to the type returned from the procedure not to thetype for the param.Am I doing something stupid here? Did I create my stored procedurewrong?Any help would be appreciated.Thanks.Jon
