The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Getting Firebird embedded working in java

Asked by ethnarch in Interbase / Firebird Database

Tags: firebird, embedded, java

I am trying to get my java application to connect to a firebird embedded database and so far i keep getting errors currently i am getting this error

org.firebirdsql.gds.impl.jni.InternalError: FirebirdApiBinding::Initialize - Could not find or load the GDS32.DLL
        at org.firebirdsql.gds.impl.jni.JniGDSImpl.nativeInitilize(Native Method)
        at org.firebirdsql.gds.impl.jni.JniGDSImpl.attemptToLoadAClientLibraryFromList(JniGDSImpl.java:85)
        at org.firebirdsql.gds.impl.jni.EmbeddedGDSImpl.<init>(EmbeddedGDSImpl.java:31)
        at org.firebirdsql.gds.impl.jni.EmbeddedGDSImpl.<init>(EmbeddedGDSImpl.java:21)
        at org.firebirdsql.gds.impl.jni.EmbeddedGDSFactoryPlugin.getGDS(EmbeddedGDSFactoryPlugin.java:40)
        at org.firebirdsql.gds.impl.GDSFactory.getGDSForType(GDSFactory.java:219)


In order to get to this point i dropped both the fbembed.dll and the gds32.dll(which is actually just the renamed fbembed.dll) into the c:\windows\system32 folder.

I then tried dropping all kinds of other files including the intl folder from the firebird embedded download and the firebird.conf and firebird.msg

I also tried putting them directly in my lib folder it still cannot find the the gds32.dll.  

Any ideas on what i am doing wrong or where the gds32.dll should go?

oh yeah the connection url i am using in my project is this
        try{

            Connection con = null;
            Driver d = (Driver)Class.forName( "org.firebirdsql.jdbc.FBDriver" ).newInstance();
            con = DriverManager.getConnection("jdbc:firebirdsql:embedded:C:\\Database\\userdb.fdb", "sysdba", "masterkey");
            System.out.println("sqlUtilities.getResultSet:Database connection established");
            Statement stmt = con.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_UPDATABLE);
        }catch (java.sql.SQLException e){
            System.out.println("exception: Message-" + e.getMessage() +" ToString-" + e.toString());
            e.printStackTrace();
}

the error occurs after the DriverManager.getConnection

and i should add also i have firebird 2.0 superserver installed and running on my system possibly is this causing a conflict?
