CloudScape database

I downloaded SDK Enterprise 1.3 which i believe to contain CloudScape inside. The problem is i don't know how to get the interface up and running. Any help is appreciate it. I just want to use Cloudview GUI to create a database to run with my J2EE application. Please instruct me as to what i need to do.

First you need to download the Java 2 Standard Edition (formerly the "JDK") at:
http://java.sun.com/j2se/1.3/download-windows.html (scroll down and click the "continue" button).
Once downloaded, install it into the directory of your choice. I prefer c:\jdk1.x
Then, install the J2EE to the directory of your choice. Again, I prefer c:\j2sdkee1.x
Now, open C:\j2sdkee1.x\config\orb.properties and make sure host is set to localhost (it can be whatever you want, really, but localhost is the de facto standard).
Now, open C:\j2sdkee1.x\config\web.properties and change the port to 80, if it's not already.
Now, add these lines to the beginning of the j2ee.bat and cloudscape.bat files:
set JAVA_HOME=c:\jdk1.x
set J2EE_HOME=c:\j2sdkee1.x
Now add cloudscape jars to your system's path.
I'm running Windows 2000. This is what I appended to my system's path variable:
c:\jdk1.3\bin;C:\j2sdkee1.2.1\lib\j2ee.jar;C:\j2sdkee1.2.1\lib\cloudscape\client.jar;C:\j2sdkee1.2.1\lib\cloudscape\client.jar;C:\j2sdkee1.2.1\lib\cloudscape\cloudscape.jar;C:\j2sdkee1.2.1\lib\cloudscape\RmiJdbc.jar;C:\j2sdkee1.2.1\lib\cloudscape\tools.jar
That should do it, I think.
You can run cloudscape with:
C:\j2sdkee1.x\bin\cloudscape.bat -start
You can run J2EE by running:
C:\j2sdkee1.x\bin\j2ee.bat
Now open your browser, and go to:
http://127.0.0.1, or http://localhost
I'm sure there are other ways to configure and run everything. I'm sure my way is overkill, but it works for me, without any problems.
Cheers!

thanks.

Hi,
I assume you have a JDBC driver for Cloudscape.
1. In the IDE System Navigator, expand the Connections Node.
2. Right-click on the Database Connection and choose New
Connection .. .
3. Click pass the welcome screen.
4. In Step 1, name your connection and choose "3rd party JDBC
Driver"
5. Follow the rest of the steps and provide username/password,
class name and URL, test and you should be ready to go.
Good luck.

Error while connecting to Cloudscape Database

Any suggestions?

Cloudscape - JSP - Unable to create database CloudscapeDB

I created a Cloudscape database in a Java program:
try {
Class.forName(COM.cloudscape.core.JDBCDriver).newInstance();
     connection = DriverManager.getConnection(jdbc:cloudscape:CloudscapeDB;create=true);
A CloudscapeDB directory is automatically created in the same directory as my
Java program. I then ran cloudview -start from the DOS prompt, opened my database, created my tables and added data.
In another Java program, I display the list of customers:
public void displayCustomers(){
try {
Class.forName("COM.cloudscape.core.JDBCDriver").newInstance();
connection = DriverManager.getConnection(jdbc:cloudscape:CloudscapeDB;create=true);
     Statement s = connection.createStatement();
     ResultSet rs = s.executeQuery("SELECT * FROM customer");
This Java program works fine, displays the data from the customer table.
I then take this same code and put in into a JSP to display the list of customers to a web page and deploy my application using the Deployment tool:
<%
try {
Class.forName(COM.cloudscape.core.JDBCDriver);
     connection = DriverManager.getConnection(jdbc:cloudscape:CloudscapeDB;create=true);
My getConnection() method throws the following SQL Error:
SqlException Error Thrown Failed to create database 'CloudscapeDB'
I am able to access the CloudscapeDB using the same driver and URL in the Database Tool but I don't know what I am doing wrong in my JSP.
In the Deployment Tool, I have configured the Driver Class as COM.cloudscape.core.JDBCDriver and the JNDI Name as jdbc/CloudscapeDB and the JDBC URL as jdbc:cloudscape:CloudscapeDB;create=true. I am not sure I even needed to do this.
Any idea why my JSP cannot create the CloudscapeDB? I believe the CLASSPATH is configured correctly because I am able to get access to the Cloudscape database in my Java program.
Any help would be greatly appreciated.

How to resolve the datasource with Cloudspace database?

Hi,
I am running WebLogic 6.1 on Win2k and I have problem with
Cloudscape database in Default Admin Server.
=== Start init method in myJDBCReadServlet.java ===
Init Error: javax.naming.NameNotFoundException:
Unable to resolve MyJDBCDataSource.
Resolved: '' Unresolved:'MyJDBCDataSource' ; remaining name ''
=== Finish init method in myJDBCReadServlet.java ===
1. I created simple table in the Cloudscape database using IJ utility and inserted
some values:
prompt>java -classpath %CLASSPATH%;..\lib\tools.jar COM.cloudscape.tools.ij
ij version 3.5 (c) 1997-2000 Informix Software, Inc.
ij> CONNECT 'jdbc:cloudscape:demo;create=true';
WARNING 01J01: Database 'demo' not created, connection made to existing database
instead.

CONNECTION0* - jdbc:cloudscape:demo;create=true
* = current connection
ij> CREATE TABLE employee(name CHAR(25), location CHAR(20), id INTEGER);
0 rows inserted/updated/deleted
2. I created Connection Pool and Data Source using Default Console
The Connection Pool configuration is the following:
Name : MyJDBC Connection Pool
URL : jdbc:cloudscape:demo
Driver Classname: COM.cloudscape.core.JDBCDriver
Properties : user=none password=none server=none
My Data Source configuration is the following:
Name : MyJDBC Data Source
JNDI Name: MyJDBCDataSource
Pool Name: MyJDBC Connection Pool
I added the following line to myserver startup script to point
to the database location:
-Dcloudscape.system.home=./samples/eval/cloudscape/data
3. I wrote the servlet and here is the piece of the myJDBCReadServlet
code which generated the exception:
public void init()
System.out.println("=== Start init method in myJDBCReadServlet.java ===");
try {
ctx = new InitialContext();
ds = (javax.sql.DataSource) ctx.lookup ("MyJDBCDataSource");
} catch (Exception E) {
System.out.println("Init Error: " + E);
System.out.println("=== Finish init method in myJDBCReadServlet.java ===");
Why it cannot find the database using JNDI name?
Any help will be greatly appreciated,

Problem solved!
Slava - thank you for your help.
Yes, cloudscape.jar file should be on the CLASSPATH.
I also put tools.jar from the same directory (I am not sure
is it necessary or not, but I did not test it).
However,it is not enough to run WebLogic with Cloudscape
successfuly. You have to tell WebLogic where the database
files are. To do it you have to include start-up option
in the startWebLogic.cmd file.
It looks like:
-Dcloudscape.system.home="C:~\samples\eval\cloudscape\data"
After that it runs. Actually, the file cloudscape.html in the
directory ~\samples\eval\cloudscape has quite a bit of information.
Unfortunately, it is difficult to comprehend it until you understand whatthe
problem is.

This is the source of the error:
<Error> <JDBC>

but I don't know how to fix it.
I don't know the name of the Cloudscape JDBC driver.
I looked at cloudscape.jar file and found the following class file:
COM/cloudscape/core/JDBCDriver.class
Is it the right driver?
I tried to use COM.cloudscape.core.XADataSource driver
classname, but got the same problem - WebLogic cannot find it.
Which .jar file has correct Cloudscape JDBC driver?

I added some Cloudscape parameters to the startup script,

Using Cloudscape for rdbmsRealm

Using WLS60sp1 on WinNTor HP-UX I was unable to modify user information against the
shipped cloudscape
database. After boot up all users in the demo DB were displayed as expected but I
couldn't modify users settings
although the console confirmed that but nothing changed in Cloudscape. I wonder if
I missed something as this

Any ideas? Thx.

Using WLS60sp1 on WinNTor HP-UX I was unable to modify user information against the
shipped cloudscape
database. After boot up all users in the demo DB were displayed as expected but I
couldn't modify users settings
although the console confirmed that but nothing changed in Cloudscape. I wonder if

How to access a Cloudscpae database?

I have problems setting up and accessing the J2EE RI built-in database Cloudscape.
In the EJB tutorial (EJBIntro) some EJB are created during the exercises. There's
also a file named MusicStoreDB.jar which contains a prepared Cloudscape database.
In the turorial it's been told:
"Sun's J2EE Reference Implementation comes with a built-in version of the
Cloudscape RDBMS. If you are using J2EE RI, you should initially use Cloudscape as
your database to avoid configuration problems. You can learn how to substitute a
different database after you become comfortable with creating and deploying
applications using Cloudscape."
and:
"For Cloudscape, simply copy the MusicStoreDB.jar archive into the directory
%J2EE_HOME%\cloudscape and then unjar the database. (All files unjar into the
directory MusicStoreDB within the current working directory.)
One last step is needed when running with J2EE RI: You need to modify the
%J2EE_HOME%\config\default.properties file to define the datasources available
to J2EE RI. This is done by changing the line that reads:
jdbc.datasources=jdbc/Cloudscape|
jdbc:cloudscape:rmi:CloudscapeDB;create=true
(with everything on one line)
to be:
jdbc.datasources=jdbc/Cloudscape|
jdbc:cloudscape:rmi:CloudscapeDB;create=true|
jdbc/MusicStore|jdbc:cloudscape:rmi:MusicStoreDB;create=false
(with everything on one line)
and then restarting both Cloudscape and J2EE RI."
Rather than doing the changes in "default.properties" I did in "resources.properties"
but it dooesn't work.
What am I doing wrong? Can anybody help me to get the database run? How do I have to
register the MusicStoreDB within resources.properties and how can I access this database
using the DatabaseTool provided with the EJB tutorial?
Thank you.

I'm having the same problem with even the same
MusicStore demo .
I'm trying to solve it.
please let me know if you have any solution.

Create a data source and database tables using WSAD

Hi, guys:
the following is from a tutorial:
http://www-106.ibm.com/developerworks/websphere/techjournal/0306_wosnick/wosnick.html
"To create the data source and Cloudscape database tables automatically, right click on the HelloWorldServer in the Servers view, and select the Create tables and data sources menu item. A dialog will then display showing that the data source and database tables were created successfully (Figure 5)."
I am using WSAD 5.0 trial version. I cannot find Create tables and data sources menu item if I right click on the HelloWorldServer in the Servers view. I am wondering if this is because trial version does not have this feature?
regards

This question is a little off topic but you may get a reply. Please note this forum is about Sun's J2EE SDK and its related technologies. You may have better luck posting your question to an IBM specific resource.

iam getting this problem when iam accessing database 2nd time......
for the first time iam getting the values......but for the second time iam not getting above exception......please help me out

hi guys ....
i wrote on samll singleton class for db
r db connection to connect to cloudscape database in
my web application.Since you say "singleton, make sure you have enough closed the previous connection object. may be you are trying to get the same instance second time, when the previous one is not yet closed.
just my 2 cents.

JNDI with TOMCAT4.0 to CLOUDSCAPE ? need explanation

Hi All,
I'm using TOMCAT4.0 and Cloudscape.
I got below code 1,2,and 3. When I ran it, I can't look up the cloudscape database ?
(I print out "************** null ***************")
Why? It looks like there is no link between jdbc/books and cloudscape database.
How do we correct it? or what is missing in terms of network connection? Or any value that I have is incorrect?
Thanks,
Paul.
1. web.xml
<resource-ref>
<res-ref-name>jdbc/books</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
2. server.xml
<Resource name="jdbc/books" auth="Container"
type="javax.sql.DataSource"/>
<ResourceParams name="jdbc/books">
<parameter><name>user</name><value></value></parameter>
<parameter><name>password</name><value></value></parameter>
<parameter><name>driverClassName</name>
<value>COM.cloudscape.core.JDBCDriver</value></parameter>
<parameter><name>driverName</name>
<value>jdbc:cloudscape:rmi:books</value></parameter>
</ResourceParams>
3. cloudscape is running(database is OK) and I ran test.jsp
javax.naming.Context ctx = new javax.naming.InitialContext();
javax.sql.DataSource ds = (javax.sql.DataSource) ctx.lookup("java:comp/env/jdbc/books");
if (ds == null)
     out.println("************** null ***************");
else
     javax.sql.Connectin conn = ds.getConnection();

Hi Fredrik,
(Thank, Mr. Expert)
0. Cloudscape came with J2EESDK1.3 and is running.
1. Basically, I already do a test with J2EE sun server
J2EESDK1.3 and it work fine because there is physical link between
the jdbc/books and jdbc:cloudscape:rmi:books. However, it look there is no
physical link for Tomcat4.0.
2.
javax.sql.DataSource ds = (javax.sql.DataSource) ctx.lookup("java:comp/env/jdbc/books");
give me "null"
(3. I have to see why ?)
