OC4J and JDK 1.5

Hi all,
which version supports the latest JDK (1.5 or 5.0 as you
want)?
Thanks

I'm all for experimentation .. just don't call Oracle support with your experimental efforts ;-)
Thanks for posting the info.
For what it's worth, I can comment that I've tried a recent internal OC4J build from our mainline with JDK5.0 and it now works fine -- as far as I tested it anyway.
One thing to note is that if you do follow this advice and start OC4J with JDK 5.0, then if you ever revert back to starting it at a later date with JDK 1.4, you will see some problems with the compiled EJB wrapper code. This is because it was originalled compiled with 5.0 but then later is being loaded by 1.4, and a class version exception is thrown.
If you get this and do want to use JDK 1.4, the easiest way to fix it is to remove all the generated subdirectories under the j2ee/home/application-deployments directory. This will cause OC4J to regenerate and compile new EJB wrappers using the JDK 1.4 compiler.

OC4J and JDK version compatibility

Does anyone know if OC4J 1.0.2.2.1 is certified to work with JDK1.3.1?
The reason being :
1. We have a situation where the CPU gets full frequently because of OC4J.
2. When OC4J is recycled the app works fine. App uses JSP, servlets and JDBC connection to Oracle 8.1.7
3. Is there any way to find if OC4J 1.0.2.2.1 is not supposed to be used with JDK1.3.1?
Finally, is there any URL that provides this information so that I can check the same with later versions of OC4J and JDK?
Thanks,

OC4J 1.0.2.2.1 is not certified with 1.3.1.x. Certification information should be available in http://metalink.oracle.com. You should have a CSI to get into Metalink.
thanks

I am running vista, and have the latest version of the dev suite. Does anybody know how I can fix this problem?

You cannot use Internet Explorer on Windows Vista to run Web Forms.
<p>But you CAN run web forms through Netscape or Firefox. But you first need to disable Java in the browser.
<p>And to run OC4J on Vista, you need to set its compatibility mode to Windows XP.

Am I to assume that jdk1.4.x is no longer supported in JDeveloper and that I should start using JDK1.5.x? But apps built with JDK1.5.x are not supported in AppServer 10.1.2.0.2, which is J2EE 1.3 compliant... Does that mean that JDeveloper 11g is suitable only for apps deployed on OAS 10.1.3.x and above? (OAS 10.1.3.x is J2EE 1.4 compliant, and OAS 11g will be J2EE 5.x compliant).
Comments please.
Thx!

be on OracleAs 10.1.3 at a minimum<<The problem (for us) with Oracle AS 10.1.3 is that Portal 10.1.4 will not run on it (not certified). We want to take advantage of ADF RC and we hope to be able to produce JSF portlets or "portletized" apps. But at the moment we are "stuck" with 10.1.2.0.2 and JDK 1.4.x/J2EE1.3...
While you can have a 10.1.2 farm and add a 10.1.3 separate instance it is not a clean/complete integration (you can't manage all services from the 10.1.2 farm EM and others; this is what I've seen so far, IMO).
We can't wait for OAS 11g to come out and take a look at that. And I certainly hope that Portal will be certifed on 11g so that we can just jump there.
Another wish: WebCenter functionality in Portal, or Portal/WebCenter rolled out into one.

OC4J and BC4J Runtime installation for Solaris (Unix)!

We have successfully installed, configured and deployed JSP/BC4J apps using OC4J and BC4J on Windows NT/2000. However, our production environment is Solaris.
We have installed OC4J on Solaris, with some difficulties. How/where is the installation process for the BC4J Runtime Installation? The download (bc4j-ojsp.zip) for this utility is Windows only.
Is there a method or process to install BC4J Runtime on Unix? If not, we are stuck.
We cannot use JServ (servlet limitations) and refuse to use OSE (to many issues).
Any guidance or assistance would be greatly appreciated...
JDeveloper 3.2.3
iAS 1.0.2.2
Solaris 8
JDK 1.2.2_08 (Unix)

Stephan,
I have located multiple "connections" files and will remove all but the default located in the OC4J classes directory. We have been developing with JDeveloper and it often created multiple connections files that appear when you "jar" project components.
We also installed JDK1.2.2_008 and are using this. However, when I use the classpath method of starting OC4J, I receive numerous errors. Using the jar method, everything works, with the exception of BC4J apps. I'll have to look into the errors more.
Thanks for the response. At least I know one other person (organization) is using this successfully. I hope to join the "success" crowd tomorrow!
Thanks again...

OC4J and WTP JDT-compiler

Hi.
Does anyone know about OC4J and JDT-compiler compatibility ?
If I don't mistake, OC4J works officially with JDK compiled classes.
What's about JDT compiled classes compatibility ?
Thx

Hello,
Correct me if I am wrong but JDT is the JSP compiler of Tomcat, that "transform the JSP in to a Servlet". Based on this statement, I do not think it will bepossible to use these classes in OC4J since Oracle has its own JSP/Servlet engine.

Oracle 8.1.5 and JDK 1.2 Thin Driver

We are doing some prototyping with Oracle 8.1.5, BEA WebLogic
6.1, and JDK 1.3. We needed to know what is the latest version
supported by the oracle thing client drivers for that
configuration.
Or are we the only users doing this and is it mandatory that we
migrate to Oracle 8.1.7?
Thanks,

Check out the SQLJ FAQ at:
http://technet.oracle.com/tech/java/sqlj_jdbc/htdocs/faq.html
"ExceptionInInitializerError: NullPointerException"
(This is likely a general configuration issue, not something specific to your code.)
If you see the following stack trace:
unexpected error occurred... java.lang.ExceptionInInitializerError: java.lang.NullPointerException
at sqlj.framework.ClassFileReader.attribute_info(Compiled Code) ...
at sqlj.tools.Sqlj.statusMain(Compiled Code)
at sqlj.tools.Sqlj.main(Sqlj.java:117)
then you are likely running SQLJ version 8.1.5 or earlier under JDK 1.2.x or later.
You need to download the SQLJ 8.1.6 SDK patch, which contains a new translator.zip
version that you can use to replace the translator.zip from 8.0.5/7.3.4 or from JDeveloper 3.0.

OC4J and FOP installation

Hi,
We would like to use the PDF printing of 3.0.1
I am trying to install FOP but I do not have any knowledge in OC4J and Java ... so I am kind a lost right now.
I am following the installation guide of OC4J standalone (http://download.oracle.com/docs/cd/B32110_01/web.1013/b28950/install.htm#BABIBGCA)
I was wondering :
1- do I need to install oc4j standalone in a separate Oracle Home ?
2- There is already an OC4J installed in my db Oracle Home , I guess for emdbconsole. So , I created a new directory called oc4j_sa and unzipped the file. When I start OC4J with oc4j -start , it does not give me the prompt back. Then , I can access the web page with port 8888 (192.168.0.21:8888) , but 192.168.0.21:8888/em fails . So I cannot deploy the FOP war file.
Any pointers or guidance would be great.
Thanks
Francis.
P.S. :
Oracle 10.1.0.5
Oracle Linux (RH 4)

OK, I finally got to the deployment of FOP but now it generates a corrupted PDF.
Are there any log files that I can check ?
I created a new Oracle_home for OC4J and ran "EM" to deploy FOP and everything worked like in the viewlet.
Now I did the setup in APEX and set the following :
Standard Support
Print Server Protocol HTTP
Print Server Host Address 192.168.0.21
Print Server Port 8888
Print Server Script /fop/apex_fop.jsp
I created a sample application to test. In a report , I added the print link.
When I clic Print, the pdf generated is corrupted and does not work.
Thanks
Francis.

Urgent Solution needed--Problem in JSP compilation with JDK 1.5 and JDK 1.6

Hi,
I m using JDK 1.5 and Tomcat 5.0 the problem is that after starting server when I m going to access my application at that time instead of displaying HomePage it directly display the blank page on screen.
After analyzing tomcat log I have found that there was a problem with JSP page compilation.
The exception logged in Tomcat Log is given below

After getting this kind of error I have analyzed my code furhter then I came to know that there was problem with static include tag.
In my jsp page I have used following line which is the main cause of error
<%@ include file="top.jsp" %>If I ommit this line then it is working properly.
Instead of static include I have used jsp:include also.
Still I m getting same problem.
We have to migrated from JDK 1.5 to 1.6 and Tomcat 5.0.28 to 6.0.14, still same problem is there.
We have tried a lot but didnt get success to overcome this problem.
If anybody having any solution then ur each reply will be appreciated.
Thanks in advance..........!!!!!!!

If I remove the include then It is working properly.
But I need inluded file too so that I am wondoring for the solution.
This problem seems very wiered to me. I dont know why it is happening.
This problem is started only when I used the TOMCAT 6.14.
Is it the bug of TOMCAT 6.14 or What somebody Plz help.
I got stuck here.........!!!!!!!!!!
It doesn't seem any problem with top.jsp. As per my thinking the problem is there in include due to that it doesn't compile the JSP page in Tomcat 6.0.
Earlier I am having same code running on the Tomcat 5.0.28 and JDK 1.5.0.
But problem occured when I have used Tomcat 6.x...!!

CF7 and JDK 1.4.2 - EV SSL Certificate Issue

Let me start off by telling the group that we do not use CF for any of our applications. We are a payments company that hosts a .NET API in IIS that 100's of thousands of customer use. We have one particular customer using CF7 and JDK 1.4.2 who is currently unable to process against our API. About a week ago we upgraded our SSL certificates to EV (Extended Validation) and since that time our once happy customer is now unhappy. I have spent hours working with him, going through FAQs and walk throughs, knowledge bases and forums and have had no luck. Here are the details:
EV Certificate issued by DigiCert (4096-bit).
Customer is on CF7 and JDK 1.4.2.
When he attempts to process against our API with the new certificate he gets 'Connection Failure: Status code unavailable' message from his CF application. He is using cfhttp to post his requests. We found a work around that indicated that the only issue with JDK 1.4.2 was importing the high-bit certificates. Our customer installed JDK 1.6, imported the certificate (and all intermediate certificates) successfully into the cacerts file, but when attempting to list using JDK 1.4.2 is returns an invalid certificate error and still will not work.
Please help as we are currently in a work around state for this customer (not long term) and we have exhausted the resources we have access to for solving this issue.
Thanks in advance to those gurus that reply. I have attached a sample post from our customers logs with non-essential data removed.
I can be reached by phone at 801-341-5620 if anyone feels like reaching out to talk.
- Dave

Dave,
I am having a similar issue with CF7 and PayPal's Reporting API which also uses EV SSL.
I can offer that in my testing, both CF 8 and CF 9 do seem to be able to work when using CFHTTP and EV SSL,
so the only solution I can offer at this time is to make the suggestion to your customer that they need to upgrade
to either CF 8 or CF 9 to get the issue quickly resolved.
I'm still working to see if I can find a solution for CF7 and I've been asking around in the CF community for help, so
if I do find a solution, I'll definitely post it there for you.
Cheers

Report display is different in report builder, local oc4j and app server

Hi guys,
we upgrade reports from sql report writer into report 10g. In the report 10g builder,
the report format looks fine. but if i use the url as below
http://applicationserver/reports/rwservlet?report=test.rdf&userid=username/password@service&desformat=pdf&destype=cache
so the format will be mess up whatever i use this url in my local oc4j or i deployed it into 10g application server. and the format is different in oc4j and application server. Why this issue happend?
Thanks in advance,

Difference between SUN JDK V1.4.2_05 and JDK V1.4.2_07

difference between SUN JDK V1.4.2_05 and JDK V1.4.2_07 and I want to the link in SUN for that. I want to know the bug fixes between them.

Perhaps you should look at the documentation which comes with JDK 1.4.2_08.
It has the bugs fixed listed.

Urgent : Oracle AS 10.1.2.0.2 : Switch OC4J's JDK version to 1.3 ?

Hi,
We have inherited an EJB application which was written during the hey days of JDK 1.3.
We have an Oracle AS 10.1.2.0.2 & we have successfully migrated most of the other Applications / Oracle J PDK Applications which were developed using JDK 1.4. Unfortunately, we now need to migrate the older EJB application to Oracle AS 10.1.2.0.2.
We tried a few dry runs with our staging Oracle As 10.1.2.0.2 instances - unfortunately, the application's code just won't compile - it looks as if we need to rewrite our application to compile under JDK 1.4. We can do this - but, we are hard pressed for time & we are looking for a solution that can bail us out of this tight corner.
I would like to know if we can switch the OC4J's JDK version to 1.3 in any supported way ? If yes, we can just install another Oracle AS J2EE instance dedicated to out legacy ( !! ) EJB Application at this time & think about reqwiting & performance tuing at leisure.
If not, what other options to I have ? Have I provided enough information or do I need to post additional infromation ? Please do let me know if more information is needed.
Thanks in advance,
Sandeep

Hi,
We also tried to follow Metalink Note:351476.1 which talks about changing the JAVA version used to run a specific OC4J instance. However, after following the steps, when we try to start our OC4J instance, we see this error:-
D:\OraInfra\opmn\bin>opmnctl startproc process-type=OC4J_JDK13
opmnctl: starting opmn managed processes...
=============================================================================
opmn id=nac014:6200
0 of 1 processes started.
ias-instance id=OraInfra.myHost.idc.oracle.com
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
ias-component/process-type/process-set:
OC4J/OC4J_JDK13/default_island
Error
--> Process (pid=6240)
failed to start a managed process after the maximum retry limit
Log:
D:\OraInfra\opmn\logs\OC4J~OC4J_JDK13~default_island~1
Now, when I look into the log file, I see this ( !! ) :-
06/02/21 18:18:11 Start process
06/02/21 18:18:13 Start process
06/02/21 18:18:15 Start process
I understand that OC4J tried thrice before giving up, but if there are no error, I don't know why OC4J just refuses to start ? Truly, the mystery deepens....

Java Studio Creator and JDK

I'm trying to create a game application using java and i've downloaded both java studio creator and JDK. However i'm having problems of writing the program. Should i use notepad and compile it using JDK? Or can i simply use the java studio creator and type in my java codings? And i cant seem to type in any codings in the java studio creator.
Can someone help me please? Thank you.

Hello, Burpyjac!
I don't understand what you want to do exactly. If you would like to write an applet for a website maybe Java Studio Creator is not what you want, it's an IDE for developing web applications running in an application server like Glassfisch, SJSAS, Tomcat and the like.
If your game need animation, drawings in a panel and the like you would need another IDE like Netbeans for example to develop an applet. Of course you can just use Notepad, but a IDE like Netbeans is much more comfortable (syntax highlighting, project managment, debugging).
Java Studio Creator is an IDE for web applications and it is based on Netbeans (if you saw both you will notice). If your game can live without graphics maybe you can use it - but be aware that this applications do not run alone, you need an application server.
Cheers,

What's the difference between Java SE 6 Update 10 RC and JDK 6 Update 7

I want to download jdk and do some java development. But I saw "Java SE 6 Update 10 RC" and "JDK 6 Update 7" are both there for me to download. I don't know which one should I download. I used to think JDK is Java SE. Can someone explain it to me? Great thanks!

[Java 6 Update 10|http://java.sun.com/developer/technicalArticles/javase/java6u10/] provides some nice enhancements for deploying Java to the Desktop, a nice new look and feel and some other nice additions.
Also, JDK 6 Update 7 is the latest, officially released version at the moment. The Update 10 is only a release candidate (that means it is what might become the final Update 10, but can still change).
For normal development (and especially when you're just starting to learn) there shouldn't be too much difference, so choose whichever you want.
