J2eelauncher and cloudscape

Hi,
I am totally new to EJB and I'm trying to work with j2sdkee1.2.1 on Windows 98 using j2eelauncher. j2eelauncher seems to work well in starting the j2ee server and the deploytool but it doesn't start the cloudscape server. Can anyone help me figure out the problem?
Thanks,
Jai

Sure I can help you, I am using J2ee on Win 98 and Win 2K both. Mail me all your .bat files from the J2EE_HOME/bin folder, i will figure out the problem,
Cheers,

Problems on JDBC and Cloudscape

Hi,
I'm suffering from a problem I got while using Cloudscape.
I wrote a program to create a database in cloudscape. It is a very simple program. The main
part is as follows,
Class.forName("COM.cloudscape.core.JDBCDriver");
Connection conn = DriverManager.getConnection("jdbc:cloudscape:LibDB;create=true");
The java file is saved in the directory c:\myfile\Create_DB.java and be compiled to
Create_DB.class.
At the very Beginning, I didn't add cloudscape.jar to the Classpath, so I got the common
error:
java.lang.NoClassDefFoundError: COM.cloudscape.core.JDBCDriver
Later, I added those jars related to cloudscape to the CLASSPATH, a strange thing happened.
Now, the error became:
java.lang.NoClassDefFoundError: Create_DB
Then, I thought maybe I need to add the working directory to the Classpath. So, I add
c:\library to CLASSPATH. But the first error (java.lang.NoClassDefFoundError:
COM.cloudscape.core.JDBCDriver) appeared again though the cloudscape.jar was still in the
CLASSPATH.
I tried and tried, but the strange problem is still there. I really got crazy. Please Help !
I set the CLASSPATH as following:
%J2EE_HOME%\lib\j2ee.jar;%J2EE_HOME%\lib\cloudscape\system\cloudscape.jar;%J2EE_HOME%\lib\cl
oudscape\cloudclient.jar;%J2EE_HOME%\lib\cloudscape\RmiJdbc.jar;%J2EE_HOME%\lib\cloudscape\c
loudview.jar
PATH is
;%JAVA_HOME%\bin;%J2EE_HOME%\bin
Thank you for your time.

No, I don't have any packages included in my code.
You have probably already looked through most of this, but if not here are some sources that have helped me.
This is the general Cloudscape website from IBM. They have some help like FAQ and the like.:
http://www-3.ibm.com/software/data/cloudscape/
There are a couple of changes to your environment that are recommended by Cloudscape. They are detailed in the documentation at the following URL in Section 2.1:
http://publibfi.boulder.ibm.com/epubs/html/cloud50/pdf/start.pdf
In addtion, there are several ways that Cloudscape recommends that you code to load the Cloudscape driver. Surprisingly, it appears to be different for different operating systems. They are discussed in the documentation at the following URL in Section 6.
Cloudscape worked on my system without any big problems (Win2k) following the installation and changes/validation to the CLASSPATH, so I'm not very good at debugging problems related to it. However I did verify that Cloudscape was installed properly by using the utilities that come with Cloudscape. I figured that if I could install/run the utilities that the development environment was setup correctly, and removed any issues with my own buggy code. The utilities I verified with where "ij", "cview" and probably most importantly, "sysinfo". It's convenient because you can alter the environment (CLASSPATH, etc) dynamically.

Cloudscape and deploytool problem

My deploytool and cloudscape have been working well until yesterday. The error message that I received with cloudscape was
ERROR (no SQLState): Connection refused to host: 218.186.XX.XXX; nested exceptio
n is:
java.net.ConnectException: Connection timed out: connect
ij version 4.0 (c) 1997-2001 Informix Software, Inc.
And also, the deploytool cant seem to find my localhost.
Wonder if anyone knows what is this problem? It seems that my localhost is not able to host. Any help will be appreciated.

I would try rebooting cloudscape.

Username and password with Access and JDBC application

Hello all,
I have written an application which accesses a MS Access database. I have created a dialog which asks the user for a username and password. I then include the username and password to connect to the database. I have created groups and users in the Access database and have given each user different privaleges. However, when I run my application, any user can get any privelage. I am missing something. Thanks in advance.

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.

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>

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 ?)

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!

Cloudscape making me suicidal

I've been trying the whole week to get Cloudscape running. I'm about to through my computer out the window. I'm not one for giving up and really like finding the solutions to problems but this is ridiculous. I download Cloudscape from the IBM website and installed it. Now the hassles started. I realised I needed to setup the paths but I'm got so utterly confused between derby and cloudscape that it took me two days just to get that sorted out. I finally got the SimpleApp to work from the command prompt so I thought my problems were solved. WRONG!!!! I tried to now run the exact same program from JDev and it now gives me this error:
SimpleApp starting in embedded mode.
exception thrown:
java.lang.ClassNotFoundException: org.apache.derby.jdbc.EmbeddedDriverI would probably have stopped trying but all the documentation on SDN has to do with cloudscape and so does the textbook I'm using. Please can some one just point me in the right direction.

Do I need to do this in the command prompt window or can I program this into the code. I'm running the program from JDev. The driver that you mention, can you please elaborate a bit more. I'm really at a hairs end because following the tutorial just doesn't seem to help, it seems like you need to toy around with stuff behind the scene's before the program gets up and running.

How to connect to database in JSP

Hi, all.
I am using J2EE and cloudscape. I have written all the EJB classes. But now i have no idea that how to connect to database in jsp such as i get user ID from portal, then i connect to database check the existence of user ID and the password then return true or false value. how to write all this in jsp?

EjbCreate() architecture with CMP 2.0; confused

I exhaustively searched for this topic in this, and other forums, and
tried some suggested techniques, but none worked.
I've received "Primary key fields of bean not initialized" in     the following stmt.
     Entity1Remote prEntity1Remote = printHome.create( new Integer(1) );     <-- should parm. list be empty??
RemoteClient1.java contains:

     Context prenvctx = (Context) prinitctx.lookup("java:comp/env");
     Object prrefHome = prenvctx.lookup("ejb/Entity1 EJB ref1");
     Entity1RemoteHome printHome = (Entity1RemoteHome)

     /* Following causes "Primary key fields of bean not initialized" */
     Entity1Remote prEntity1Remote = printHome.create( new Integer(1) );     <-- should parm. list be empty??
     I ran using D:\zJava\zsamples\EJB\application1>C:\j2sdkee1.3.1\bin\runclient -client application1.ear -name RemoteClient1 -textauth
     I ensured j2ee and cloudscape were running, and
     set APPCPATH=application1Client.jar     (application1Client.jar was generated by the deployment tool)
The bean code contains:
     package com.zbeans;
     import javax.ejb.*;
     public abstract class Entity1Bean implements javax.ejb.EntityBean {
          public Integer property1;     /* primary key (all lower case, unless that
               breaches naming conventions?). All letters s/b in lower case to
               exactly match non-capitalization of primary key in deployment tool?? */
          /* Must the parm. variable be identically named as the primary key name?? */
          public Integer ejbCreate(Integer property1) throws EJBException, CreateException {
          //public Integer ejbCreate(Integer pnNewProperty1) throws EJBException, CreateException {
          //public void ejbCreate(Integer pnNewProperty1) throws EJBException, CreateException {
               System.out.println("\nInside Entity1Bean.ejbCreate()");     <-- this stmt. was reached
               this.property1 = property1;

               return property1;
          }     // ejbCreate() method
          public abstract Integer getProperty1();
          public abstract void setProperty1(Integer pnNewProperty1);
Entity1RemoteHome.java contains:
     package com.zbeans;
     import java.rmi.RemoteException;
     import javax.ejb.*;
     public interface Entity1RemoteHome extends javax.ejb.EJBHome {
     public Entity1Remote create (Integer property1)
          throws CreateException, RemoteException, EJBException;
Remote1Client1, Entity1RemoteHome.java, etc. resides under d:\zjava\zsamples\com\zbeans
Unsuccessful remedies:
     1) in Entity1Bean
     public Integer ejbCreate(Integer id) throws javax.ejb.CreateException {
     coded
          return id;
     instead of
          return null;
     - some newsgroup posting states that for EJB 2.0 CMP must return Primary key
          type, while others disagree (refer below)
2)
     defined ejbCreate() return type as void instead of Integer,
     and commented out return stmt. i.e.
     public void ejbCreate(Integer id)
          //return null;
     - instead of -
     public Integer ejbCreate(Integer id)
          return null;
     - this compiled clean with javac, but in deployment tool system.err
     contained:
     Entity1Bean_PM.java:76: illegal start of expression return (void)
     partition.afterEjbCreate(this); ^
     c:\j2sdkee1.3.1\repository\computer\gnrtrTMP\application1\com\zbeans\Entity1Bean_PM.
     java:76: ')' expected return (void) partition.afterEjbCreate(this);
     c:\j2sdkee1.3.1\repository\computer\gnrtrTMP\application1\com\zbeans\Entity1Bean_PM.
     java:76: cannot return a value from method whose result type is void
     return (void) partition.afterEjbCreate(this); ^
3) property1 is actually the Integer primary key in deployment tool, so tried the
following
     public Integer Property1;     /* primary key; all letter s/b in lower case to
          exactly match capitalization in deployment tool?? */
     public Integer ejbCreate(Integer pnNewProperty1) throws EJBException, CreateException {
          Property1 = pnNewProperty1;
          return pnNewProperty1;
     }     // ejbCreate() method
4) as above, but typed property1 all in lower case so it would match the
non-capitalization of the primary key in the deployment tool i.e.
     public Integer property1;     /* primary key; all letter s/b in lower case to
          exactly match capitalization in deployment tool?? */
     public Integer ejbCreate(Integer pnNewProperty1) throws EJBException, CreateException {
          property1 = pnNewProperty1;
          return pnNewProperty1;
     }     // ejbCreate() method
5) as above, but made the parm. variable identically named as the
primary key name, and modifed return stmt. i.e.
     public Integer ejbCreate(Integer property1) throws EJBException, CreateException {
          this.property1 = property1;
          return property1;          /* removing this return caused " missing return

My understanding was that for CMP2.0, ejbCreate() should accept a parm.
and return the primary key type? For my application, CMP 2.0 is
specified in the J2EE deploytool. I'm really getting confused on the
correct rules for developing the ejbCreate() in CMP 2.0 vs BMP, I've
read conflicting postings.
Instead of the J2EE Deployment Tool, am I better off learning another
server/deployer, such as JBoss, VisualAge for CSP, etc.?

I have noticed two bugs in your code:
1) You should ALWAYS use abstract get/set methods to modify CMP fields
of EJB 2.0 CMP entity bean.
Instead of
this.property1 = property1;call
setProperty1(Integer pnNewProperty1);2) you should return null in ejbCreate() method
"The entity object created by the ejbCreate<METHOD> method must have a unique primary
key. This means that the primary key must be different from the primary keys of all the existing
entity objects within the same home. However, it is legal to reuse the primary key of a previously
removed entity object. The implementation of the Bean Provider?s ejbCreate<
METHOD>(...) methods should be coded to return a null.[14]"
I hope it helps

PortableRemoteObject.narrow causes NoClassDefFoundError

tried some suggested techniques, but none worked.

I was thinking of moving RemoteClient1.java one level higher in the

- should I move the .java, and .class files from c:\jrun4\...\classes\com\zbeans

Cant get rules to work with pz:div tag

im using commerce server 2.0.1 with sp1
i made a rule sheet and rule and rule selectors through the wlpsadmin
tool
and then i was trying to base content inside a portal using one of the
rule selectors and the pz:div tag.
this is what the jsp page has inside:
<pz:div
ruleset="jdbc://com.beasys.commerce.axiom.reasoning.rules.RuleSheetDefinitionHome/myRules"
rule="myRule">
content
</pz:div>
the server just hangs for about 5 minutes, and then no content is
returned. there is nothing coming out in the weblogic.log the whole
time. i have checked the rules and at least one should be returning some
content
previouly i have been getting other errors such as

no i am sure it is not the database, i use oracle and cloudscape
interchangingly. i never got the jsp tag to work, however i got around it by
using java code. they have a class called ContentSelectorExample which you can
use to exceute a rule. here is my code that seems to work:
<%@ page import="com.beasys.commerce.axiom.content.Content" %>
<%@ page import="examples.p13nadvisor.ContentSelectorExample" %>
<%
// this is the rule sheet you made in the commerce server admin at wlpsadmin
String
ruleSet="ejb://com.beasys.commerce.axiom.reasoning.rules.RuleSheetDefinitionHome/myRules";
// this is the rule you made in the commerce server admin at wlpsadmin (content
selector rule)
String rule="myRule";
Content[] results = null;
String contentHome = "com.beasys.commerce.axiom.document.DocumentManager";
String sortby = null;
String query = null;
int max = 1;
try{
results = new ContentSelectorExample().executeContentSelector(pageContext,
ruleSet, rule, contentHome, sortby, query, max);
// check if there are any results - this tells you if the rule failed or
succeeded
if(results != null && results.length > 0){
%>
<P>Content for when the rule is a success</P>
<%
} catch(Exception ex){ ex.printStackTrace(); }
%>

May I ask what RDBMS are you using? I'm using MSSQL 7.0. I just want to make

Rmi Server Exception

Hello Everyone,
I encountered the following errors during deployment using J2ee's Deployment Tool.
I have an Entity EJB called Books using Cloudscape as the database. When I clicked on 'Generate SQL Now' in Deployment Tool, I received the following errors. "java.rmi.ServerException, - nested exception - connecting to database - no suitable driver".
Prior to deployment I have j2ee server, cloudscape database up and running. Cloudscape has the following Driver Class - COM.core.RmiJdbcDriver, COM.cloudscape.core.RmiJdbcDriver 1.7.2. The Database JNDI name is jdbc/BooksInCloudscape. I tried to re-register the driver in j2ee and cloudscape, then brought both servers down and up with no luck. I have put c:\Books\classes in my CLASSPATH.
Could anyone please shed lights on this issue? Thanks in advance.

I am having the EXACT SAME ISSUE. I've been to countless message boards and support sites to no avail (I'm assuming you are also working from EJB 2.1 Kick Start by Peter Thaggard.)
If you've resolved this issue from another source please update this posting any help would be greatly appreciated. I can't express how much time has been wasted on this simple connectivity issue.

Petstore demo install under Win2000

Hello:
Trying to get my arms around J2EE. A large task.
Anyway.
I have downloaded the J2EESDK and installed it.
I can start the Application server and run the Hello demo.
I can also run the App Server Admin Application, so I
think I got that right.
I want to work with the Petstore demo. So I downloaded
petstore-1_3_2.zip. I am following the enclosed install
instructions. When I run setup I get the following:
My environment is below also.
The Petstore demo seems to be built on top of Cloudscape.
But the J2EE SDK installs PointBase, is there a way around this.
Need some help. Please
thanks

I had this same symptom, and it was because I was trying to use Petstore version 1.3.2 with the J2EE 1.4 SDK.
There is an updated version of the Petstore sample application in the J2EE 1.4 samples bundle located at... http://java.sun.com/j2ee/1.4/download.html#samples. It is included as part of a group of three "J2EE Blueprint samples" and they can be run with the J2EE 1.4 SDK (whereas the old one's can't). (Note that the Buleprint samples are also included in the "All-In-One Bundle" and are located in the in the \AppServer\samples\blueprints directory.)
If you download the samples by themselves, their documentation won't specify that they must be installed in the \AppServer\samples\blueprints directory, but they must because the ant build script references at least a couple of other files in the samples directory heirarchy (common.xml and common.properties).
These are two samples of error messages I got when I was trying to build the Petstore application from outside the context of \AppServer\samples\blueprints directory heirarchy:
C:\blueprints\petstore1.4\src>asant
Buildfile: build.xml
C:\common.xml could not be found
BUILD FAILED
java.io.FileNotFoundException: C:\common.xml (The system cannot find the file specified)
