Quick Java version question...

I'm unable to use VNC while connected through a semi-restricted VPN tunnel into work (I have to visit a certain website at work and when I click a button an Aventail application springs into life and I get a VPN tunnel). My work doesn't support Macs, so I spoke to tech support for the VNC vendor and he assured me they support Macs. He said to make sure I'm running version 1.5 or 1.6 of JRE (Java Runtime Environment) and Safari. I don't know how to determine that - anybody out there able to help?

Thanks for the reply - I'll give this a try when I get home later on. It does seem a bit odd that I was asked to inquire about JRE, but this Java Preferences application talks about JSE. I don't suppose they're the same thing?...

Quick java udf question

Hi sorry for this completely stupid question but the below piece of code I am trying to dissect and understand.
I understand the first line I am creating a new global container but the second line I am not so sure what the (integer) would be for. Is this meant to be a variable or a return type? What could that possibly be for I mean a type in parenthesis after the equals sign.
GlobalContainer gc = container.getContainer();
Integer counter = (Integer) gc.getParameter("counter");
Thank you for your help.

GlobalContainer is a container object stores values and can be retrieved by UDF during runtime. This GlobalContainer stores values and can be accessed by any UDF in the same namespace. This is similar to class variable or static variable of java class.
In your case, It has a parameter which is set as ("counter", Integer) . Basically it is a key value pair and very similar to Hashtable in java.
Example
setParameter(String str , Object Integer);
>What could that possibly be for I mean a type in parenthesis after the equals sign.
typecast to integer in paranthesis, because we store the value here as Integer object.
Integer counter = (Integer) gc.getParameter("counter");
expecting return type is Integer.

Java version question

I am a little bit confused with the compile version and run version. I have a 1.4 SDK, but I have to develop an applilcation that will run on a 1.3 environment. Is the option "javac -target 1.3" sufficient to make sure that my application will run on a 1.3 environment? I use many 1.4 features in my program, such as JSSE, I wonder whether a 1.3 JVM will understand what are those things. Also, can I tell my 1.4 JVM to run like a 1.3 one? Or I must download a 1.3 JVM to test my program? Any help would be appreciated.

To absolutely assure that a program will run on 1.3, it need to either
1. Be compiled by 1.3, or
2. Be compiled by (say) 1.4 using the -target 1.3 and -bootclasspath options. Using the -target option alone may or may not work, depending on code usage and changes that were made in 1.4..
This information is detailed in the javac documentation here http://java.sun.com/j2se/1.4.2/docs/tooldocs/windows/javac.html
You should read and understand this if you need to cross-compile versions.

JDeveloper and Java Version question

I would like to know how to change the version of java that JDeveloper is using. I have 1.5 installed on the machine, yet the default version is 1.4 which i can see what going into help. How may I change JDev so it uses 1.5?
Thank you,
Russ

Set the JDK version with Tools>Project Properties>J2SE Version field.

EM Question (Java version)

Hi Guys,
I have a question about EM (Java version, not the web based one).
Lately, we are having issues displaying tablespaces and datafiles informations.
It takes up to 10 minutes just to display the datafiles from a tablespace (when double-clicking on a tablespace name). Then it takes another 10 minutes if we click on a datafile to display the information of that datafile. Samething if we apply a change.
Is there anything we can look at to solve this situation?
Thank you,

How do I downgrade to a specific update of Java version 6?

I am used MBA Mountain Lion OSX.
I am trying to use Business Objects through the web and unfortunately Java 7 is not compatible. I was able to downgrade to Java 6u65 (Java 1.6.0_65) but I really need update 45 to get Business Objects to work. Can anyone help me with the terminal code and/or a download that will allow me to pull out Java version 6u45? (Java 1.6.0_45)?
I've been on here trying several other's codes and it says permission denied or "unable to find any JVM versions matching 1.6.0_45"
Could that mean I don't have version 6u45 available to me period?

Just wanted to post the answer in case others have the same issue. I had to remove ALL java related files in order to install an earlier version and there was ONE transient file that I couldn't find and this code worked

Java version and amount of SAPDATA

Hi!
I would like to install SAP Solution Manager on Solaris Sparc 10 Zone (64 Bit) with Oracle.
Questions:
1) Which Java version applies for the installation? I have installed 1.4.2.12.
2) Is that problem that the <sid>adm user exist already on the server?
Or should I delete these, because thes will be created with SAPINST?
I run Installation as root-user
3) How much SAPDATA do I need for the installation. I would abolish to have more than 3 SAPDATA. So I have 3 SAPDATA, each 70 GB. Is that ok?
Thank you very much!
regards
Thom

Hi Thom,
1) Which Java version applies for the installation? I have installed 1.4.2.12.
Answer: Please go through the note 716604, and also 1.4.2_12 version for JDK is fine. You can go with this.
2) Is that problem that the <sid>adm user exist already on the server?
Answer : It wont be the problem if it exists,but check the owner and modes as per the guide and change it.
3. should I delete these, because thes will be created with SAPINST?
Answer: Yes,users will be created by SAPINST,but if its already exists, you dont need to delete this. If you dont know the changing of owners or modes for the sidadm user. you can delete, it will create by SAPINST.
4.I run Installation as root-user
Answer: Yes. you have to start installation with root user.
5.3) How much SAPDATA do I need for the installation. I would abolish to have more than 3 SAPDATA. So I have 3 SAPDATA, each 70 GB. Is that ok?
Answer: SAP recommends 4 sapdata's. The size is depends on how much data you maintain in the system. Try to create SAPDATA4 and distrube the size to all 4 sapdata's.
Hope you understand this.
Thanks

Java Georaster API error - wrong java version

Hi all. I've done some searching about but cannot see this question answered (or indeed asked) anywhere else so perhaps i'm the first person to encounter it.
I've got some georaster data from a customer in an Oracle DMP file which i've imported. It all checks out as being valid (using sdo_geor.validategeoraster) but i cannot view it in the Georaster Viewer tool. I wrote some java to extract a piece to a file but i get this error with the select command ...
DEBUG <10:27:51> [GeoRaster] jGeor.getRasterImage(conn,0,600, 1199, 1801, 2400 )

John.

Looks like the code is explicitly checking for a specific version of Java without doing a greater than check, you'll have to trick the API
Before you call the JGeoRaster Method, call:
String temp = System.getProperty("java.specification.version");
System.setProperty( "java.specification.version", "1.4.1" );
the after call:
System.setProperty("java.specification.version", temp);
Alternatively, the JGeoRaster library that comes with 11g has a fix for this issue.

Java Version for ERP 2005 and Oracle 10.2.0.1

Hi all,
I've just a question. I'm trying to install ERP2005 on Windows 2003 Server with Oracle 10.2.0.1.
But the process terminates at the step "Import ABAP" with the error messages concerning "CJS-30022 Program 'Migration Monitor' exits with error code 103 " and " FCO-00011 The step runMigrationMonitor with step key".
I've had a similiar abort with another installation. Could the java version cause this error? Which java version is recommended as standard in regard to our ERP2005-installation?
Please help me !!
Thanks in advance.

10.2.0.1 is not supported.
you have directly update 10.2.0.1 after the installation to 10.2.0.2 and then install at least hotfix 10.2.0.2.12 (current is 10.2.0.2.13).
Using older version of Oracle 10.2.0.2.12 will cause a lot of problems.
By the way, are you installing a blank new ERP2005 or are you performing a systme copy?

Java -version error

Hello,
I am installing 11.1.1.7 Soa Suite etc, and given all the talk about Jrocket, decided to give that a spin. I am on Windows 7
when I do a simple java -version I get the following:
[WARN ][osal   ] Could not enumerate processes (1) error=-1073738819
[WARN ][osal   ] Could not add counter (null)\ for query
[WARN ][osal   ] Failed to init virtual size counter.
java version "1.6.0_45"
Java(TM) SE Runtime Environment (build 1.6.0_45-b06)
Oracle JRockit(R) (build R28.2.7-7-155314-1.6.0_45-20130329-0646-windows-x86_64, compiled mode)
I tried checking the lodctr /q (from Could not enumerate processes (1) error? | Marcus Hirt) as suggested on the bottom of this page Re: Web Logic server 10.3.5 not running , but everything looks ok -- nothing is disabled in the lodctr /q output.
I was able to get a weblogic a quick domain running, but also got these errors when starting the domain.   Should I abandon Jrocket? Can I expect it to function properly regardless of these warnings?
Any suggestions?
Thank you,
Stuart

When I do the same on my environment do not see the warnings you are encountering:
C:\bea\jrockit-jdk1.6.0_45-R28.2.7-4.1.0\bin>java -version
java version "1.6.0_45"
Java(TM) SE Runtime Environment (build 1.6.0_45-b06)
Oracle JRockit(R) (build R28.2.7-7-155314-1.6.0_45-20130329-0646-windows-x86_64, compiled mode)
What can be the case is that your machine is not actually 64-bit, i.e., that the hardware virtualization extensions (VT in the case of Intel) of your processor are not enabled (this is just a guess) - steps on how to do that are provided here: https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Virtualization_Administration_Guide/s….
"Should I abandon JRockit?" No I think not, some examples that included WebLogic and JRockit set-up can be found here: Middleware Snippets: JRockit. All in all JRockit runs very smooth (never had any problem with it), but if the warnings do not go away, it is better to use something else (you never know what these lead to in a production environment).

Flash/java remoting question

Hi,
i'm new to flash remoting and am finding using it with java
quite troublesome. I've also found using the FileReference class
troublesome if you use java. my question is can you somehow tie the
remoting functionality to the FileReference.upload method
fucntionality??
thanks in advance

I will use the program with photo detector to test
the response time of the LCD screenWhy Java?I second that. With a test like that, you want to reduce the experiment down to a single variable, in this case the lcd response time. Using a java program to feed the monitor input introduces a second variable, the response time of the program. The java program's timer may not be exact, the components may not be repainted completely quickly enough, etc. If this is just for your own amusement, maybe that doesn't matter, but if you want your results to have any reliability, you'll need a more accurate and controllable input source.

Upgrade Java version in DB server.

Hi,
in my db server current version is:
[root@prod-db /]#java -version
java version "1.4.2"
To install TSM for oracle (tape backup) i was asked by SA to update server java version to jre1.7.0_07. But i have never done any work like this. Can any one help??

Actually i don't want to touch oracle/oracle software , i just want to upgrade java without hampering my oracle.Then you need to update the Java version installed in the o/s - and ignore what is installed in Oracle as that is not relevant to your problem.
What do you have installed? What Java components do you need?
You can check what is installed and available using the yum command. Basic Java can be installed using the java-<version>-openjdk.x86_64 package I think.
This is not a database question though, and I suggest that you either re-post your question to the {forum:id=822} forum, or that a moderator moves this posting there.

Java version 6 update

I love my Mac and have enjoyed nearly flawless operations for over 3 years now. Software update offered the latest Java version 6 update last week. I have downloaded other Java updates over the years and have never had any problems, so I downloaded version 6. Now I can not get into an important web site that I use for business. I read the discussion topics in here and someone said, "don't forget to repair permissions". What does that mean and exactly how do you "repair permissions"...??? Any information or help would be appreciated.

Finding the minimum needed Java version to run app

Hello, I have created an application and would like to distribute it. However, I would like to know the minimum Java version that would be needed to run the app. Aside from digging through the APIs, would there be any tool that would help with that task.
(P.S. I'm sorry for any cross-posting that may occur, I did not know what this would fall under).

Doesn't answer the question, which java version did you use?
In eclipse, pull down the help menu and select About Eclipse SDK, then click the Configuration button. In the dialog that comes up near the top is a section with java.??? look for the one that say java.home and see which version of the jdk it's using, then go to your project, right click on it and to go properties. Under Java Compiler in the tree view you will see JDK compliance. That will tell you absolutely which version(s) of Java are involved. The one in the compiler compliance is the one that the system trying to run your application must have.

How to determine the Java version in Windows XP

In Windows 2000, I can determine the version of Java that's running by typing 'java -version' in a command prompt. However, when I type this in a command prompt in Windows XP, a message says 'java is not recognized as an internal or external command ...'.
Is there some other means of determining the version of Java that's running on Windows XP?
Thank you.

I found the directory with java.exe on my XP client. After updating my Path and then typing 'java -versions' I still see a 'java not found message'. No problem though - a README.TXT says that I have JRE 1.1.7B.
One final question - a co-worker who also has XP just starting seeing a pop-up window saying 'Runtime' error when running a Java applet. His java.exe is in a path that includes the sub-directory 'JRE' On my XP client, java.exe is in a path which includes a 'JRE11' sub-directory. We therefore seem to have different versions of the JRE. Since I don't see the Runtime error when running the same applet, should my co-worker try upgrading his JRE?
Thank you.
