JDev 2 and JDK 1.2.2

How do I add JDK 1.2.2 as an option for JDev to use? I didn't find it in the JDev help? Did I miss it?

Company policy prevents me from download JDev 3 from the net. To order it, will take months. And Oracle for the sequent comes out way behind other platforms, so I cann't take avantage of JDev3's latest features.
So Can i just install JDK 1.2.2 and jdk 1.3 and use the "Define" button to include them in the list?

JDeveloper 11g and JDK 1.4.2_16

Hi! I just created a new simple app in JDev 11g and selected the JDK 1.4.2_16 for the model project. I created a set of business components from tables, built the project and them attempted to run the AppModule tester.
I got the following error:

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.

JDeveloper 9.0.5.2 and JDK 1.5

Hello all,
Af far as I can see, JDeveloper 9.0.5.2 seems not to be able to work with JDK version 1.5 (Java 5). The new version of JBuilder is already able to do this. Can anyone tell me which version of JDeveloper will support JDK 1.5 and where I can find information about this.
Kind regards,
Ronald

The next major version of JDeveloper will have JSK 1.5 support.
Meanwhile this thread:
Jdev 10g and J2sdk1.5.0 beta
Explains how you can hack a 1.5 support in the current version.

Problem creating reference heap snapshot with JDev 11g and OAS10g

Has anyone successfully configured OAS 10g and JDev 11g for reference heap snapshots in the memory profiler?
I have configured the server in opmn.xml and the client in JDeveloper. I can start the server and connect the JDev profiler and start and stop the use case.
I do not, however, see any results in JDevelopers References panel, and I get an I/O error when stopping the use case
"Profiler snapshot I/O error reading input file D:\profile\myfile.opi". This binary file is actually written, however.
The Java start parameters in opmn.xml are:
-agentlib:profiler15=port=4627,
jarpath=D:\jdev\lib\profiler-agent.jar,enable=r,refpath=D:\profile\myfile.opi
Environment:
OAS v10.1.2.0.2,
JDeveloper 11g, Techonology Preview 4 (11.1.1.0.22.49.49),
JDK 1.5,
Windows

Hi,
Thanks for the input, I'll refer my questions to that group.
I can add that we have successfully profiled JVM memory usage and garbage collection on OAS10g using JDev 11g. See
Re: Memory Profiling OPMN changes
It's only the reference heap snapshot feature that does not seem to work for us in this setup.
Thanks again,
Niels Erik

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?

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.

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..........!!!!!!!

Hi "mshanu" and "amit" Thanks for ur replies Here I m posting the code of "top.jsp"........!!!!
<%@ page errorPage="errordisplay.jsp"%>

</table>To include top.jsp I have tried
<jsp:include page="top.jsp" flush="true">
</jsp:include>
         AND
<%@ include file="top.jsp"%>but none of this worked.
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

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.

JDev 10g and EJB 2.0 on non-OC4J server

It looks like JDev 10g only supports EJB 2.0 for OC4J out-of-the-box. Is this correct?
If we wanted to generate EJB 2.0 CMP entity beans etc to deploy to a non-OC4J app server (e.g. JBoss) using JDev 10g, what would we need to do? Are there any tutorials/how-to's available?
As a newbie to JDeveloper and J2EE, trying to work out how to re-write our Forms system in J2EE, I have to say I'm getting tired of how most of the JDev documentation - and much of the software - only seems to relate to using OC4J (or 9iAS) as your app server. If we and our customers wanted to be restricted an Oracle app server, we could just stick with Forms 9i and save ourselves a world of Java pain.
Plus, nearly all the 10g client documentation relates to JSP clients, but we want a rich GUI using Swing (JClient would be useful but we can't figure out how to deploy it 3-tier to JBoss).
So, Oracle, how about giving your users some more documentation on how to use JDev10g/JClient/ADF/EJB 2.0 etc with non-OC4J servers and perhaps even without JSP?
I am sure that JDev10g and ADF could offer us a great deal of help in building our system, if only we could figure out how to use it.
Thanks,
Chris

Thanks, Deepak.
But the how-to is for old versions of JDev/JBoss:
"This document was written for Oracle9i JDeveloper Release Candidate and JBoss 2.4.4 (Dated December 29, 2001), although other versions of Oracle9i JDeveloper and/or JBoss should behave the same."
I'll let you know if this works with JDev 10g and JBoss 3.2.3, but I have my doubts.
If anybody has some more recent information on this, please let me know!

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.

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.

Returning arrays using JDBC 2.0 and JDK 1.2.2

I am able to return a varray from an PL/SQL stored procedure to a Java program using the Oracle JDBC 8.1.6 driver classes (oracle.jdbc.driver.* and oracle.sql.ARRAY). I want to avoid using the Oracle specific classes to do this and instead just use the standard JDBC 2.0 classes and JDK 1.2.2. Will I still be able to access the varray returned by the PL/SQL SP or am I forced to use the Oracle classes?
Why I ask this is because the Java code needs to be usable from a Netscape Application Server 4.0/iPlanet Application Server 6.0 servlet or java class. NAS 4.0 uses the JDBC 2.0 classes but I cannot use the Oracle JDBC 8.1.6 classes since NAS 4.0 requires the Oracle 8.0.5 client. iAS 6.0 provides a JDBC 2.0 type 2 driver and uses the Oracle 8.1.5 client but does not support arrays, i.e. CallableStatement.getArray(), ResultSet.getArray(), etc. are not supported.

JDBC 8.1.6 (2.0) and JDK 1.2 java.sql.SQLException

I wrote an applet program and access to Oracle database using JDBC 2.0 (Oracle 8i 8.1.6). When testing, I got errors java.sql.SQLException: No suitable driver.
Who havd any idea to solve this problems.
It works fine when I use JDBC 1.2 and JDK 1.2 .
Chuleerat.

"No suitable driver" usually means that the
connect string is incorrect.
The 8.1.6 driver supports JDK1.1 and JDK1.2.
If you use JDK1.2, the JDBC 2.0 features
are available to you.

How to identify the installed Weblogic Server and JDK are 32bit or 64bit?

Hi everyone,
I have a question ~
Both Weblogic Server and JAVA JDK are installed on the server already, but I only know the Weblogic Server is 10.3.4.0 and JAVA JDK version is 1.6.0_25.
I know the 64bit Weblogic Server installation file is a wlsXXXX_generic.jar package and 64bit JAVA JDK needed also.
But, since the Weblogic installed already, there are no such installation files on the Linux Server now.
I have tried the "java -version" for java version and check the Weblogic version from Weblogic console.
How to identify the installed Weblogic Server and JDK are 32bit or 64bit with Linux command? Or is there any way to check it?

What you can try to do is use WLST (or an MBean browser, such as JConsole or JRockit Mission Control) and connect to the adminserver.
For example when using WLST:
# set the environment by using setWLSEnv.sh (located in the ${WL_HOME}/server/bin directory).
# start WLST by using: java weblogic.WLST
# connect to the adminserver
connect('adminusername','adminpassword');
# change to the serverruntime environment
serverRuntime();
# show the attributes
ls();
# Here an attribute is shown called WebLogicVersion that shows the version of WebLogic
-r-- WeblogicVersion WebLogic Server 10.3.5.0 Fri Apr 1 20:20:06 PDT 2011 1398638
# Note that this does not show if is 32 bits or 64 bits to retrieve this information you have obtain the JVM version
# change the directory
cd('JVMRuntime/AdminServer');
# show the attributes
ls();
-r-- Version R28.0.1-21-133393-1.6.0_20-20100512-2126-linux-x86_64
# when you have something like x86 at the you are running a 32 bit version, if you have something like x86_64 you are running a 64 bits versionAs mentioned above you can also retrieve this information by using a MBean browser.

JAVA_HOME, JRE and JDK

Does anyone know what JAVA_HOME should be pointing to if only the JRE in installed? What it should be pointing to if the JDK is installed?
On Windows, I notice that c:\program files\JavaSoft gets created after install. For which install does that happen? For the JRE and JDK install? Should JAVA_HOME be pointing to that directory?
I couldn't find any java.sun documentation about the role of the JAVA_HOME env var. If anyone can piont me to some, that would be appreciated. :-)
Version: 1.3.1
Thanks in advance.

Dear dinogg
Does anyone know what JAVA_HOME should be pointing to
if only the JRE in installed? What it should be
pointing to if the JDK is installed?
set JAVA_HOME=C:\jdk1.3.1\bin
On Windows, I notice that c:\program files\JavaSoft
gets created after install. For which install does
that happen? For the JRE and JDK install? Should
JAVA_HOME be pointing to that directory?
actually it is for jre but when u install jdk it also install jre if you notice there is a part setting up java runtime environment
I couldn't find any java.sun documentation about the
role of the JAVA_HOME env var. If anyone can piont me
to some, that would be appreciated. :-)
