Two versions of java on same OS

I have installed on my OS (Windows 2000 Prof) two versions of SDK (v.1.3.1 and respectively v.1.4.0).
I want to compile and run some application with one version or another.
What changes do i make in order to set one version (for use in compilation and running) ?

It depends on what IDE you work with. Or if you compile and run at the command prompt, use a batch file to set the correct values for the required variables.

Running two versions of java, is it possible?

Hi everyone, I've got two applications, both incorporate applets, but one uses 1.3 and the other uses 1.4. Im stuck as I need to run these two programs at the same time. The reason I cant just use 1.3 is because one uses JTree's which were introduced in 1.4 (am I correct?) . SO if thats the case, is there anyway to use two versions of java on the same machine.????????????
Thank you
Graham

I've got two applications, both incorporate appletsYou have two applets.
one uses 1.3 and the other uses 1.4. One requires at least 1.4 (you think)
I need to run these two programs at the same time.
The reason I cant just use 1.3 is because one uses JTree's which were introduced in 1.4 (am I correct?) .The 1.3 API Spec includes JTree
So if thats the case, is there anyway to use two versions of java on the same machine?Why can't you just use 1.4

Two Versions of JAVA

Hi,
We are planning to upgrade EBS11i to 12. Till now we used Jinitiator to bring up the applet from the Client machine but EBS12 uses Java 1.6_07 version.
we have discoverer 10.1.2.0.2 that uses Java 1.4_x version and now EBS that uses version 1.6_07
Question is:
Can we configure two java versions on the same client machine for different application.
Thanks in advance.

Two versions of XSD with same namespace in one project

I'm working with a two very large version of the same set of XSDs. For some uses I need to use the old version for other the new ones. They use the exact same namespace. So when I include them in the same project there is overlap and conflicts. The schemas are very large and separated into 66 different xsd files. Also they are maintained by another group. Manually altering the xsds is not really an option.
The way I've been getting around this problem up until now was to have one process that can receive message for the old version and one for the new. This is a lot of overhead.
So I was wondering whether there is a way to deal this without altering the xsds?
Thanks

Hi,
have you thought about putting a version string into the namespace?
Or you can write scripts, which put new XSDs in all processes and deploy them....
I think you will not get such a feature for free. Perhaps, you will get some other approaches here, so you can choose the right solution for your problem....

every time I've tried to install JEE6 so far I had to manually tell the installer where to find the JDK...I would just use the Glassfish installer directly, it works very well even when there are multiple runtimes installed (at least on my computer).

Installing two versions of ELS on same computer

Hi all.
What are the thought processes behind installing more than one version of the ELS (2.5 and 6.1) on the same Windows based PC?
Are there any known issues?
Thanks all.

Two Versions of Itunes on same Computer

Hey guys, my brother has an Ipod and I'm going to get one. I was wondering if Windows can run two Itunes on the same computer. Since Itunes goes with a certain Ipod, I just wanted to know if I install it will it delete his Itunes, or will it not show up at all for me.
Thanks

Two versions of Developer, same machine

I need to use a single machine to access two different applications, one using Developer 2000 v4x and one using Developer v6. What is Oracle's support stance for a machine that has two different versions of Developer loaded on it? Can it work efficiently and/or effectively? How? Thanks for any help.

You can install different versions of Developer on a same machine. Some of the Developer versions supports multiple ORACLE_HOME installations also.
eg: Forms/Reports 6i can be installed in a separate ORACLE_HOME.
The Release notes lists all the Developer versions which are supported on same ORACLE_HOME.
Following are the versions of Developer which can be installed on the same ORACLE_HOME as Developer 6.0,
1. Developer 1.6.1
2. Developer 2.1
Best Regards,

Hi Rai,
Sorry about my previous message. Anyways As I was saying I'm trying to Install Developer 2.1 and Developer 6.0 in the Same machine. By default both installations are install in the same Oracle Home Directory C:\ORANT and the same registry Key ORACLE. For Develop 2.1 I have to make some changes to the Registry under the ORACLE key. How can I make this two version coexist in the same machine? What version I have to install first to have a succesfull installation?
Is there any instrucion I can reference to in the Web?
your reply will be greatly appreciated..

Using two version of Crystal Report Application Server simultaneously

We are currently using Crystal Report Server XI Release 1 in a production environment, and we would like to test Crystal Report Server XI Release 2 in a test environment, on the same network.
Is there a way to be using those two versions simultaneously on the same network, using the same license key, for test purposes ?
If our tests are conclusive, we will upgrade our production environment to Release 2.
Thank you
Anthony Arnaud

As long as they are not on the same computer this is a rather comon configuration as best practices dictate that customers should maintain multiple environments (DEV/UAT/PROD) for example.
If you are trying to install both on the same server it's not supported with those 2 versions and is known to cause issues where neither will work (different story if using unix and different port numbers).

Two versions of code, one compile failure with java.lang.OutOfMemoryError

I Have two cvs versions of one package. The differences between the two are minor, and I'm only trying to make the root version look like the latest branch. When I compile the branch, which has more code, things are fine. When I comple the root version I get
java.lang.OutOfMemoryErrorSInce I can compile one version, it is clearly not the case that I lack RAM or something like that. What might the problem be? Thanks.
Ken

I'm compiling and I'm doing it with ant. As I said,
it works fine with a slightly updated version of the
Java package I have, but has this error while doing
the same compile on the cvs root version of the
package. I'm just trying to prepare for mergning the
new code but can't compile the basic version of the
package.Then, as already stated, the difference between the two versions is enough to cross the threshold of heap memory available to the VM that's running the compiler. Ant lets you provide VM options to an externally invoked VM. See its docs for how. If you're using fork="false", then just change or add -Xmx in ant.bat or ant.sh.

Itunes two versions of the same album?

Hello,
I have two versions, high res audio and CD quality, of the same album of an artist located in two folders "Album Title" and "Album Title HD".
By adding the two folders to the iTunes mediathek, all tracks are merged under "Album Title" in iTunes. Do I have to manipulate the meta data to avoid this behavior in iTunes? Interestingly the views on the Mac and via iOS Remote App are different:
Mac:
Track 1
Track 1 HD
Track 2
Track 2 HD
etc.
Rmote App:
Track 1
Track 2
Track Last
Track 1 HD
Track 2 HD
I disabled the automatic handling option for iTunes import. So still two folders in the iTunes music folder exist.
Any ideas?
Andreas

If you want them to appear as separate albums you will have to change the metadata for one of the albums. There are many ways to do this and which one you use will depends upon your preferences.
You can make it obvious by doing something such as adding a descriptor to the album name e.g., Album Name [CD quality]
You can "hide". If you do not normally use the album artist field and you add an album artist to that field for one of the versions it will cause that to sort separately. Similarly if you add a number to the disc number field that should normally get it to display separately.
Alternatively you can come up with a smart playlist to sort according to kind.

Can I have two versions of firefox at the same time?

Hi,
Probably a dumb question but can I have two versions of Firefox on my system at the same time?
The reason is because of Add Ons that are not compatible with v4. I'd like to be able to close v4 when I need to use an Add On in v3.
Thanks.

You can install them both but there are a few steps to take.
When you install Firefox 4 use the custom installation option and choose a different location to install Firefox.
In order to use both versions, you need to create a new profile for Firefox 4 (Firefox stores user data in the profile). Using the same profile with different versions can cause problems. Once you create a new profile you can copy certain data such as bookmarks and passwords between them. You can also use Firefox Sync to keep the profiles synchronized. Finally, you will need to set up shortcuts to launch the correct profile for each version.
The following links show how to do this:

* http://kb.mozillazine.org/Shortcut_to_a_specific_profile
* http://kb.mozillazine.org/Transferring_data_to_a_new_profile_-_Firefox
* https://addons.mozilla.org/firefox/addon/firefox-sync (only needed for Firefox 3.6, it is built into Firefox 4)

When I OCR two versions of the same document and then compare th documents in Acrobat Pro XI, I usually get the message that there are no changes to mark. However, I know there a quite a few number of changes. I raised this question more than a year ago

When I OCR two versions of the same document and then compare the documents in Acrobat Pro XI, I usually get the message that there are no changes to mark. However, I know there a quite a few number of changes. I raised this question more than a year ago, and the response I received had to do with the quality of the OCR and the scans of the documents. However, if I use Acrobat Pro XI to save the same documents in Word and then run a comparison in Word all of the changes are marked. When a PDF is saved as a Word document in Acrobat Pro XI, is a different OCR module being used than the one used in Acrobat Pro XI for text recognition?

OCR is only for recoginition of the image / picture of text provided by an scanner.
Content typed into a Word file which is converted to a PDF is (in Word and in PDF) *not* an image or picture of text - it is the digital text. So, no OCR involved.
When the "digital" (renderable) text of a PDF's page content is exported to Word no OCR is involved.
When a PDF's content is from the image output of a scanner and this is a picture of text then OCR comes into play.
If this content is exported to Word before doing OCR then it is the image that is exported to the Word file.
Once OCR is performed it is the OCR output that is exported.
OCR output is (always will be) impacted by "the quality of the OCR and the scans of the documents".
Regardless "Compare" is based on a Word file output to PDF1 then edits to the Word file followed by an output to PDF2. You use Acrobat Pro to do a compare of PDF1 & PDF2.
Paper 1 scanned to image 1 to image 1 in PDF1 that gets OCR 1 and
Paper 2 scanned to image 2 to image 2 in PDF2 that gets OCR 2
being processed with Acrobat Pro's Compare can certainly be done.
But - well you've described what can be observed.
Be well...

Can I install two versions of SOA suite using same Oracle database

Condition:
I installed Weblogic server(10.3.5) and SOA Suite(11.1.1.5), and
I used RCU 11.1.1.5 to create the schemas(Oracle DB 11g-111170) for it.
Plan:
Now I plan to install another Weblogic server(10.3.6) and SOA Suite (11.1.1.6)
and I will used RCU 11.1.1.6 to create the schemas for it.
Question:
Can I use same database(Oracle DB 11g-111170) for the two versions of SOA Suite? that is
Can I Run the RCU 11.1.1.6 to create the schemas for SOA Suite (11.1.1.6) on the oracle database server I already used for SOA Suite 11.1.1.5?
If I can use same database for the two versions of SOA Suite, how can I resolve schame name conflict?

Hi
1. YES. You can absolutely use SAME DB to have multiple Versions of SOA Schemas.
2. Any SOA/BPM will need basically 4/5 schemas like SOAINFRA, MDS, ORABAM, ORASDPM etc. based on what you choose. And each of these Schemas can be Prefixed. Default prefix is like DEV, so schemas are like DEV_SOAINFRA, DEV_MDS etc
3. Very Simple. When you Run RCU 11.6 and give the same old db details, in next screen it will automatically show the new Prefix for the schemas it will create. If DEV is used, it will show DEV1 like that. So just choose a Different Prefix and you are good to go.
I have the same thing on my side. Single Database. Multiple RCU for SOA 11.5 and SOA 11.6 with different Prefixes:
SOA 11.5 -> DEV115_SOAINFRA, DEV115_MDS, DEV115_ORABAM etc
SOA 11.6 -> DEV116_SOAINFRA, DEV116_MDS, DEV116_ORABAM etc
I Used the Prefixes like DEV115, DEV116 so that I know exactly which version of RCU schema they refer to.
For QC, UAT, PROD we used prefixes like QC_*, UAT_*, PROD_* etc.
NOTE: When you drop the schemas for some reason, make sure to give the appropriate prefixes so that only they are dropped and not others.
Thanks
Ravi Jegga
