Can OC4J ru on JDK1.6?

Hello,
We are using oc4j_extended_101340. In the README.txt I see that it runs on JDK 1.5.
We also ran into problems on Linux when we ran into an error.
In our application we have code which runs faster on JDK 1.6
How can we make OC4J run on Linux on JDK 1.6?
Thanks in advance
Regards Leon

Well, this is not completely true. JDK 1.6 is supported on certain OS and product combinations. You should check the Certify tab in metalink.oracle.com (Support contract required.)

Deploy app on standalone OC4J running on jdk1.6.0_04

Hi all!
I am trying to deploy an application on standalone OC4J running on jdk1.6.0_04. The application runs well when started on embedded oc4j (which is running on java 1.6). I know that jdk1.6 is not supported, but the application works smoother and faster on 1.6 and I want to try and find the reason why it won't work on standalone oc4j. When I start the server (start_oc4j.bat with JAVA_HOME set to c:\Program Files\Java\jdk1.6.0_04) I get these messages:
Starting OC4J with command: "c:\Program Files\Java\jdk1.6.0_04\bin\java.exe" -XX

Running into the same issues; been juggling between JDK 5/6, Embedded and Standalone OC4J on various platforms; still no answer...
Here's what I do know:
OC4J on TN is for TP1 only, JDeveloper is for TP3 or later, so you must use the bundled OC4J with JDeveloper cross platform as well - including all patches like SOA and friends.
JDK 6u4 is very bad; use anything but that; u5 seems good.
A good start might be to go with the Emedded OC4J, take a look at the classpath and startup commands given by the IDE for the server in the logs and simply match with some bat file if you can - from the looks of it the Standalone OC4J is behind thus the reason it's only released for TP1.
I'm not bothering with this till they pair a release with a Standalone OC4J.

Can OC4J 10 and OC4J11 support jdk 1.6?

Can OC4J 10 and OC4J11 support jdk 1.6?

No not really. You will have to check above mentioned Oracle's certification matrix to make sure Oracle Application Server supports desired JDK on the platform you have.
Thanks

Can oc4j work with Cloudscape together?

Can I embedd cloudscape in oc4j ?

Hallo Avi,
I did the instructions you said there. But I got a "Database connection is closed" Exception when I enter the Store. It seems that the Cloudscape database is not found or recoganized by the oc4j. Why this?
I configured the Datasourse like this:
<data-source
class="com.evermind.sql.DriverManagerDataSource"
name="InventoryDB"
location="jdbc/InventoryDataSource"
xa-location="jdbc/xa/InventoryXADS"
ejb-location="jdbc/InventoryDB"
url="jdbc\:cloudscape\:rmi\:CloudscapeDB;create\=true"
connection-driver="COM.cloudscape.core.RmiJdbcDriver"
inactivity-timeout="30"
/>
<data-source
class="com.evermind.sql.DriverManagerDataSource"
name="EstoreDB"
location="jdbc/EstoreDataSource"
xa-location="jdbc/xa/EstoreXADS"
ejb-location="jdbc/EstoreDB"
url="jdbc\:cloudscape\:rmi\:CloudscapeDB;create\=true"
connection-driver="COM.cloudscape.core.RmiJdbcDriver"
inactivity-timeout="30"
/>
<data-source

connection-driver="COM.cloudscape.core.RmiJdbcDriver"
inactivity-timeout="30"
/>
Have you any idea?

How many PCs can OC4J at Sercer contains Clients?

I've an Oracle DB 10g Server, and Oracle Developer Suite 10g.
I run the OC4J at this server and tried to run a form at a client.
It works successfully, But my question is:
How many clients can be contained by this OC4J instance?
By other words: Can I make this OC4J Instance as an Application Server for many clients? and how many clients can be contained in it?
Thanks

Thank u a lot Paul.
But this is not the asnwer that I search for.
I'll explain more:
1. I have installed Oracle DB 10g and Oracle Forms 10g.
2. I built a form (by a data block connected to DB) called person and saved it at F:\work.
3. I run the OC4J from Start >> Oracle Developer Suite >> Forms Builder.
4. I opened the FireFox Browser at another computer connected to my computer by a LAN, and then wrote the form link:
http://<my_host_name or my_ip>:8889/forms90/f90servlet?form=F:\work\person
5. the form works successfully at this computer.
My Question is: If I want to do the step no 4 for other many computers, how many computers can this OC4J instance carry?

Weblogic 10.0 Comatability with JDK1.6

I have installed weblogic 10.0 on unix machine. And when i istalled it JDK1.5 will automatically installed with it inside weblogic folder.
And when i create a new instance of weblogic with existing JDK1.5 the instace will start properly and application executes also.
But when i point the weblogic to JDK1.6 at the time of instace creting. it will not work properly. When i stop the server below error is display.

My question is that Weblogic 10.0 is only comapatable with jdk1.5 only or either any way so we can point it to JDK1.6

WLS 10.0 is not supported for JDK 6.
This is strict violation that you need to use only JDK 5

Rather I get a Java Web Start button on the
desktop...
Whats the problem?I guess the problem is that the JDK wasn't installed to the directory you specified, but somewhere else. Because installed it was, you wouldn't see the Webstart icon otherwise.

Database Web Services and OC4J in Oracle Database Standard Edition

Hi all,
Oracle Database Standard Edition has database web services, which require OC4J if the database is to be used as web service provider. So, can OC4J be used in production with Oracle Database Standard Edition?
Thank you for this clarification :)

Yes. :)

Running JDK1.4.1 on SPARC 20 (SunOS 5.7) reports "Needs SunOS 5.6 or later"

Hi, I've been using Java 1.1.6 which came with the Solaris 7 CD for a while and decided that I'd replace it with a newer version. Anyway I've downloaded and installed the recommended patches and installed j2sdk-1_4_1_01-solaris-sparc.sh in /usr/local. I've modified the /usr/java symbolic link to point to the new directory.
Everything seemed to be installed correctly yet when I run any of the programs (e.g. java -version) all I get is the following message:-
"Need Solaris 2.6 (SunOS 5.6) or later."
Which is strange since I'm already running Solaris 7/2.7 (SunOS 5.7)
uname -a reports
SunOS blah.blah. 5.7 Generic_106541-23 sun4m sparc SUNW, SPARCstation-20
Has anyone any suggestions? Can anyone confirm if JDK1.4.1 will work on Solaris 7 running on a SPARC 20?
Thanks

Solved the problem myself.
Gave up on 1.4.1 and installed the older version JDK1.3.1_06 which complained about "libthread.so was older on your system than the one the JVM was tested with". This seemed odd since I installing patch 106980-19 for JDK1.4.1 (JDK1.3.1 requires 106980-16 or later). Anyway I removed patch 106980-19 and then reapplied it and JDK1.3.1 started to work. I then set the symbolic link back to use JDK1.4.1 and found that it was now also working.

How to set proxy in code by JDK1.4 ?

Here are two ways to set proxy in 5.0,
1, public static void init() {
    Properties prop = System.getProperties();
    prop.put("proxySet", "true");
    prop.setProperty("http.proxyHost", "10.10.10.14");
    prop.setProperty("http.proxyPort", "8080");
} 2.Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress(("host"), 8888));
URL url = new URL("http://forums.sun.com");
HttpURLConnection con = (HttpURLConnection) url.openConnection(proxy));Now, method 2 could not use in 1.4, and I don't want use method 1.
Please help me provide a method can use it by jdk1.4 just like No.2
Thanks!

prop.put("proxySet", "true"); That does nothing. Try setting it to 'false' and see. This property is an urban myth.
Now, method 2 could not use in 1.4, and I don't want use method 1.So you are out of choices.
Please help me provide a method can use it by jdk1.4 just like No.2There isn't one. Obviously.
What you should do is upgrade to 1.6. 1.4 is past its End of Life and hasn't been supported for some years.

Migration from weblogic6.1 to OC4J

Hi,
We are evaluating OC4J to migrate our application (EJB2.0). Currently we are evaluating weblogic6.1 too. We have 66 local entity beans and 7 session Facade(for those local Entities) beans. It's perfectly working with weblogic.
Here I would like to mention that OC4J talks NOTHING about how to specify OC4J-specific XML descriptors. 'How to create EJB2.0' compatible stuff are already provided by SUN & co. OC4J-docs must also say how to deploy it into OC4J. HOW CAN "OC4J" EXPECT THE DEVELOPER TO START EASILY TO MIGRATE FROM another APP-SERVER?
Allright, this is the problem we are facing after INVENTING some of "how to specify OC4J-specific XML descriptors" on our own. Please correct me if anything is incorrect.
When we tried to deploy into OC4J, we couldn't invoke local entity beans using JNDI lookup.
Weblogic gives two tags "jndi-name" & "local-jndi-name" to specify JNDI names of remote & local respectively.
Orion has only one 'location=' attribute to specify JNDI location for a bean, for Entity beans presumably it takes for remote-beans, even if I don't specify any remote home/interfaces.
OC4Js 'How-To: Implement Local Interfaces' says that we need to have 'ejb-local-ref' in each referring ejb. In that case I've to create atleast 50 'ejb-local-ref' tags in each of my 7 session beans. Is that really OK?.
I would like to know whether there is any way of specifying JNDI names for local CMP's in one place, not in all other referring EJBs.
Please advise.
Thanks,
Sasikumar.

Hi Sasikumar,
In order to fully understand your situation, please answer the following
questions:
1. Are you using the latest, standalone, production version of OC4J
(version 9.0.2.0.0)?
2. Are you using Java 2 SDK version 1.3.1_02?
3. Are you using Windows2000?
4. Are you using the latest, production version of JDeveloper 9i?
5. Have you read the documentation for OC4J -- available from
http://tahiti.oracle.com
6. Do you know about the "BEA to Oracle Migration Kit"?
http://www.oracle.com/consulting/start/BEAmigration/intro.html?src=1260040&Act=8
and
http://technet.oracle.com/products/ias/pdf/weblogic_migration.pdf
7. Do you know about these other, OC4J related web sites:
http://www.orionserver.com
http://www.orionsupport.com
http://www.atlassian.com
http://www.elephantwalker.com
8. Do you know about these tools for automatically creating EJB related
files (including XML deployment descriptors)
http://beust.com/cedric/ejbgen/
http://opensource.itplus.dk/EJBCreator/index.html
http://www.myhtg.com/product.html
So if you haven't exhausted all of the above, I suggest you do so
before throwing a tantrum about OC4J. If you have exhausted the above,
and you still can't work with OC4J, then I suppose you could always
just stick with BEA (couldn't you :-)
Good Luck,
Avi.

Jdk1.4 installation question

Presently, I have jdk1.3.1 installed on a Windows
2000 Profession box. Do I have to uninstall jdk1.3.1
before I install jdk1.4 or can I just install jdk1.4
into a different directory? What happens in the
registry if both are installed?
Thanks in advance,
[email protected]

No need to uninstall jdk1.3,but the "Runtime Environment" will be changed.So If you want to use jdk1.3,you should compile with some parameters.

OC4J Hot Deployment/Extended deployment

Hi
Although this question has been asked over and over again, i couldn't find any real solution for my problem... so i'll ask again.
Context:
I've started recently using JDeveloper 10.1.2 and it's embedded OC4J server. I was previously working with Eclipse and Tomcat (with tomcat sysdeo plugin).
In my previous senario, the deployments where made in a directory structure (exploded, not packaged), allowing a more fast reload from the container (when i compiled a class tomcat would automatically reload its context... not always this would work properly, but, still, it mad development a whole lot easear).
Problem:
I'm not able to do the same in Jdev/OC4J. Every time i compile a knew class, i have to start the server all over again, witch is a really tedious task... (each start can take more then five minutes, many times only to realize that i had done something wrong and have to restart).
Question:
Can this go faster? Can OC4J make extended deployments? If so, will that mean that i don't have to generate the hole ear file each time a make some change in a class?
Or just, how do you develop in OC4J in a more productive away?
Thanks in advance
kim

Hello,
It is possible with OC4J to have the application automatically reloading the resources in development. It is documented in the deployment guide:
- Automatic Deployment

Oc4j 10.1.2.0.2 and Fedora

We have Oracle 10g AS 10.1.2.0.2 deployed at an enterprise level. I am working on a JSF application that will be deployed to this server. As I work on this application I would like to deploy it in stages to a local copy of oc4j 10.1.2.0.2 on my workstation.
I am using Fedora FC6 x86-64 for my workstation and in the installer exits due to an operating system check. Can oc4j 10.1.2.0.2 be installed on FC 6 o(or any version of linux not on the official support list)?
Thanks
Brad

I solved the problem. The original download was the "j2ee and web cache" download from the Application Server area. I later found a link to oc4j downloads from the JDeveloper pages that was really what I was after.

Binding default action of JTextComponent with JDK1.2 & 1.3

Hello,
I have a specific text component who extends JTextField. This component must work on JDK1.3 & 1.2.
I catch certain key events in the method processComponentKeyEvent to have the control over my component (in particular VK_BACK_SPACE, VK_LEFT and VK_RIGHT) and I don't want the default action inherit from JTextComponent to be exectued. With JDK1.2 this problem doesn't appear because I think the event is consume when it is thread by the processComponentKeyEvent and the operation of searching in the default key actions is not executed. But, with JDK1.3 they change the model of mapping key to event and the default actions are executed although the event is passing by the processComponentKeyEvent and e.consume was call. I find something who work on JDK1.3 by binding the default actions of key events with a "null" action. I do something like :
myField.getInputMap().put(myKeyStroke, "none");
My problem is that my components must work both with JDK1.3 & 1.2 without having two different versions of the component but the solution doesn't compile because getInputMap(KeyStroke, objectKeyToAction) doesn't exist on JDK1.2.
I try to removeActionFromKeyStroke method but it doesn't work and in plus, the change going to apply to all text component in the application.
There is a solution who can compile on both JDK1.3 & 1.2 ?
Is it a good idee to use reflection to test the presence of the method and apply the correction or you have a better idee.
Tanks a lot
Fred

Try using a KeyListener instead. It allows you to consume the KeyEvent, at least it does on JDK1.3.
keyListener = new KeyAdapter()
     public void keyPressed(KeyEvent e)
          switch (e.getKeyCode())
               case KeyEvent.VK_RIGHT:
                    e.consume();
                    // add your code here
                    break;
               case KeyEvent.VK_LEFT:
                    e.consume();
                    // add your code here
                    break;
};

Can OC4J ru on JDK1.6?
