Derby database

Hi all,
Trying to get Derby up and running. I have set up the following Environment Variables:
DERBY_HOME: C:\Apache\db-derby-10.3.1.4-bin
CLASSPATH :
.;C:\Program Files\QuickTime\QTSystem\QTJava.zip; %DERBY_HOME%\lib\derby.jar; %DER
BY_HOME%\lib\derbytools.jar;
I'm trying to created a new database from the command prompt but keep getting an exception:
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/derby/tool
s/ij
I'm really not sure what I'm doing wrong because I when I run the sysinfo.bat I get the required output. I'm trying to run the ij tool with the following line when I get the error.
C:\Apache\db-derby-10.3.1.4-bin>java org.apache.derby.tools.ij

I see that I can run the ij command from the \bin directory but then when I create the database its in that directory and not the folder that I created for the database. When I check the log I also see something peculiar:
Database Class Loader started - derby.database.classpath=''From what I see here there is no classpath?? I'm I correct in my assumption or is that the way it should be.
When I echo the CLASSPATH I do see the derby.jar and derbytools.jar paths added to the list.

How to use Derby database in embedded mode in WebLogic 12c?

I have a JavaEE-6 application that uses Derby database in embedded mode. It uses JPA for persistence. Everything works fine in Glassfish but now I am trying to port it to WebLogic 12c and having issues setting up Derby database in WLS in embedded mode. The derby setup in WLS asks for Host/port and does not have the embedded mode option. Any help is appreciated.

I'm pretty sure this is the wrong forum. "Oracle Application Server" is iAS, not WebLogic.

How to use Electroserver's built in Derby Database?

hello. I am trying to create an online multiplayer game with electroserver like here:
http://gamesfromjames.weebly.com/pickit.html
I was looking at the source code from electrotank. Unfortunately, I cannot compile it in flash CS6 because the document class is in mxml.(if someone can help me figure out how to test these examples in pure as3 that would be great) I did find these two functions in hte mxml class:
             * Increases your rank by the amount specified by sending a properly formatted message to the plugin.
            private function addToRankClicked():void {
                var ipr:PluginRequest = new PluginRequest();
                ipr.pluginName = "DatabasePlugin";
                var esob:EsObject = new EsObject();
                esob.setString(PluginConstants.ACTION, PluginConstants.TAG_ADD_TO_RANK);
                esob.setInteger(PluginConstants.TAG_ADD_TO_RANK, rankDeltaStepper.value);
                ipr.parameters = esob;
                _es.engine.send(ipr)
             * Loads your rank from the database by asking the plugin for it.
            private function getRank():void {
                var ipr:PluginRequest = new PluginRequest();
                ipr.pluginName = "DatabasePlugin";
                ipr.zoneId = -1;
                ipr.roomId = -1;
                var esob:EsObject = new EsObject();
                esob.setString(PluginConstants.ACTION, PluginConstants.TAG_GET_RANK);
                ipr.parameters = esob;
                _es.engine.send(ipr)
Is this all that is needed to put things into the database and take things out or am I missing something?
If I was going to try to save the chat history and show it every time a user enters the chat room, how would I go about doing it with electroserver's derby database?
Thanks!

Use Flex/Flashbuilder to compile mxml source code.

Problem creating parent child relatioship in derby database

hi.i m trying to develop a code that can access two tables using derby database.The data in the tables should go from the JTable of GUI which i have prepared.To read both table's properties i m using two different instances of java.util.Properties.using InputStream i m reading the properties and then i try to create the tables.The parent table is created but the child table is never created.Also i m able to insert as well as fetch the data from parent table but the child table,as not created throws Derby's error messages.
I need help in this matter.
Could anybody give suggestions?

The problem in creating a child table is that i m using two different .property files for two tables,one for parent and one for child table.I perform all the steps similar to those i performed to create parent table.But i dont know,somehow it creates only parent table and all the time when i run the code the error message for the child table comes that the table does not exist.

Help with Derby Database Performance.

I have started Derby as our BackEnd in microERP application.
with Swing as front end. But i am struggling with Performace of the derby database.
I have tried every thing with Preparedstatement and all related thing,
Please give me a suggetion..

However I would be really surprised if Derby came anywhere to even close to the performance of Oracle/MS SQL Server for all situations.
So if you picked Derby inappropriately for the needs of the business then you have a problem.

SUN application server does not read from Derby database

Hello,
I have developed a simple web application in SUN Java Studio Creator 2, and deployed it to the SUN App server 8. It uses a database (PointBase) for some table lookups. It all works OK on my development system. When I try and run the same web application on Production (Sun Java System Application Server Platform Edition 9.0 (build b48)) , with the Derby database, I cannot get it to work. The application looks OK, all web pages get displayed correctly, but none of the fields and tables show any data from the database tables.
The "ping" command from the admin screen in the app server to the Derby connection pool is successful, and there are no error messages in any logs, it is just that the data from the tables does not get displayed on the web pages. Very strange.
At first I thought it was a database issue, so I ported the database to mySQL, but the problem was not fixed. In development the web application works OK, but on production the data in the tables do not get displayed.
Anyone has any ideas?
Thanks!!

Are you able to access the data in the tables using standalone java client. ( java program through JDBC api )
Can you post the code snippet of getting connection ( URL, other db parameters)

How to Integrate DERBY Database to XI?

I am tying to store an XML format data recieved from a web service to Derby Database of Netbeans Studio.
Is this possible then which XI adapter should I use in the Communication channel configuration?
Any help will be great?

Hi,
How are you planning to upload the database. Are you planning to go with direct DB access from XI oe any shared folder,where you store this data and then some batch program etc uploads the database..
First of all sender side, you can use SOAP adapter as you mentioned it is a Webservice.. But in the receiver I am not sure JDBC adapter does support this.. first of all you can find out about database properties, drivers etc.. like MS SQL etc..
Then you can think of JDBC adapter. Else, you can dump the file into database repository and then some other job will upload the data..
Just my views
Rgds,
Moorthy

Apache Derby database not working

I am running a Windows 2003 server with Coldfusion 8. I was attempting to update the Apache Derby database to the latest version. I copied the following files to the "\Coldfusion8\lib\" directory and replaced the existing files:
derby.jar
derbyclient.jar
derbynet.jar
derbyTesting.jar
derbytools.jar
After replacing these files, I haven't been able to get my Apache Derby embedded databases working. I've downloaded all of the versions of Derby from the Apache website and individually replaced the files in the "\Coldfusion8\lib\" folder. I shut down CF, replaced the 5 files, and restarted the server; all without any luck.
Any ideas on how to restore Apache Derby functionality to my server would be greatly appreciated.

how to restore Apache Derby functionality
Restore the original files you replaced!
If you want to use version of Derby other than the one CF ships with, install it separately.

Importing from a Derby Database to Oracle

Hello,
Is there a tool that can help keep a Derby database and an Oracle instance in synch? We have a Derby database with many tables that we want to regularly migrate to our Oracle instances.
Thank you for any information.
Regards, Tony

Hi!
On a more constructive note here are a couple of thoughts:
1. Create a CSV file use either a query tool (derby provides a very simple one) or having the developers write an extract in java. Then use SQLLDR to load the data.
2. Have the developers write a java program that connects using JDBC to both the derby and oracle databases, then do what ever synching your data requires.
You may have to create a user or role for them to be able to do this.
An interesting thought is to use java in the Oracle DB and writing a java stored procedure and similiar to above make a jdbc connection to derby to extract the data that you need.
Hopefully you have gotten this solved before now. Let us know what your solution was!

Point Database tutorial but using Derby Database in NetBeans IDE

Hi
I am getting an error when I am trying to run the EJB Entity beans BMP example "savingsaccount" in the examples folder of j2eetutorials .
I have using NEtBeans IDE + Sun APP server and the following the tutorial Netbeans + J2ee tutorials...
THe problem is the tutorial talks about a "pointdatabase" 8.1 verson and the Sun App Server I have is 8.2 which has "Derby Database".
However I made the necessary changes in the code. Siill the error is someting like this :
"ar 27, 2006 3:40:57 AM com.sun.corba.ee.spi.logging.LogWrapperBase doLog

So I am not sure whether this is some fault of the application or the database access errior...?
Someone who tried this let me know plz...
thanks

Microsoft SQL Driver 2005 JDBC Driver is not the Derby driver.
You need the correct JDBC driver for the database you are using, you can't simply grab the first one you find.

Connecting to Derby database

Well I switched over from Notepad++ to Netbeans to simplify the GUI processes. And of course by simplify I mean almost eliminate. In any case now that the basic underlying information needs have been identified and I have a GUI, the next step is an appropriate database for said information. However I am having some issues creating and connecting to the Derby database.
I have already gone to Tools > Libraries > New Library, "JavaDBEmbedded" with the following classpath and Javadoc. All is good so far.
C:\Sun\sdk\javadb\lib\derby.jar
C:\Sun\sdk\javadb\javadocI used the following statement(s) to load the driver. I tried this both within the class and a method for a button. Within the method the first try is fine, however I am still getting an error for the second try.
private void jButtonCreateActionPerformed(java.awt.event.ActionEvent evt) {
//Create the database below
//Load the following driver
try {Class.forName("org.apache.derby.jdbc.EmbeddedDriver");}
catch (Exception driver) {}
try {Connection dbConnection = DriverManager.getConnection("jdbc:derby:Map1;create=true", "Username", "Password");}
catch (ClassNotFoundException ex) {ex.printStackTrace();}
//Create the database above
}Driver Manager doesnt strike me as a variable. Which is saying to me its trying to set one variable equal to another. Which means there is a problem creating a new instance of the "Connection" class?? Is there something I need to import to use the connection class?
Cannot find symbol
Symbol: Class Connection
Location: jPanelMain
Cannot find symbol
Symbol:variable DriverManager
Location: jPanelMain

It's a class that provides a static factory method called getConnection that returns a java.sql.Connection for some given parameters. You can find more information about the Driver Manager class (and the getConnection() methods in particular) here. You need to import java.sql.DriverManager and java.sql.Connection.

Accessing a Derby database inside of a Jar file...

Hello,
I've browsed many threads that touch on aspects of this topic, but I still can't seem to figure this out. Here is my dilemma:
[1] I have a simple application that stores some data using JavaDB.
[2] Everything works fine when I bundle the app into a jar, as long as I leave my Database folder outside the jar
[3] If I include the DB in the jar the app does not see it.
[4] I can't just leave the folder outside the jar because I eventually plan on deploying the app as a Web Start program.
The Dev guide on JavaDB says +"A database can be in one of many locations: in the current working directory, on the classpath, in a JAR file..."+, and this apparently can be set using the derby.system.home property. I currently use the following to set this property: System.setProperty("derby.system.home", ".myDatabase"); How would I need to change this to allow the app to find the database inside the jar? If this requires the DB to be read-only (which is fine with me), what properties need to be set to designate the DB as such?
Any input would be greatly appreciated.

Well, upon rereading the Derby Developer's Guide I found the information I sought in the section "Creating Derby databases for read-only use" (p.34-37). I'm still not 100% sure about how to do the Web Start implementation, but this should put me on the right track.
[UPDATE IN CASE ANYONE STUMBLES UPON THIS THREAD] It seems that the issue with Web Start is that the database needs to be access a writable location for the temporary directory, so I presume web start would have to request disc-access privileges... something I'm trying to avoid.

Transferring contents in MsAccess database to Derby database

I have an Ms Access Database "school".
Is there a way by which I can transfer the Ms Access database "school" to derby database.
Thankyou in advance.

If you read more about the JDBC classes such as DatabaseMetadata, ResultSetMetadata
You might be able to write your own program to do the migration.
Also if you do some search on the web you might be able to find some code that someone else has already written.

How to insert a java object int derby database

hi,
i have a problem , ie..i want to insert my java object int database derby.and also i need to retrieve that object from database whenever i need. Any body help me to do that in derby...
Thanks

Or you would design a table where the columns of the table correspond to attributes of the object. Then you would make a row by writing out the attributes to the columns they correspond to.

How do i connect to a derby database created in Netbeans externally?

I've created a a Java DB in Netbeans, I can connect to the Java DB server and then to my database from Netbeans. I need to use this database outside of Netbeans... a table from this database is used in a program which i created with netbeans... i open the program using the .jar file outside of netbeans... but i can't access the table.
can anyone help me with this?

what exactly are you wanting to do? to connect to the database i use this
String driverName = "org.apache.derby.jdbc.ClientDriver";
            Class.forName(driverName);
            String url = "jdbc:derby://localhost:1527/table name";
            String username = "username";
            String password = "password";
            connection = DriverManager.getConnection(url, username, password);you need to make sure that you have the derbyclient.jar file in the librarie for your project.
