Re: URGENT!!! Downgrade WebObjects 5.3.* to 5.2.4 as well Java 1.5.* to 1.4.2_09

Fri, 08 Jun 2007 09:24:43 -0700 

Hello Group,
It seems I have almost got the solution for WebObjects 5.3.* to 5.2.4 as well Java 1.5.* to 1.4.2_09 with the help of Kieran and Daniele. Here-in am jotting down the steps, please advise if there are any issues: 

Downgrading Java:


Java version can be easily changed by making the CurrentJDK  soft  
link point to 1.4 in the directory:
kieranbook:~ kieran$ cd /System/Library/Frameworks/JavaVM.framework/ 
Versions/
kieranbook:/System/Library/Frameworks/JavaVM.framework/Versions kieran 
$ ls -al

total 40
drwxr-xr-x   11 root  wheel  374 Apr  3 17:17 .
drwxr-xr-x   10 root  wheel  340 Mar  7 14:09 ..
lrwxr-xr-x    1 root  wheel    5 Mar  7 13:57 1.3 -> 1.3.1
drwxr-xr-x    8 root  wheel  272 Jan 31 20:25 1.3.1
lrwxr-xr-x    1 root  wheel    5 Mar  7 13:57 1.4 -> 1.4.2
drwxr-xr-x    9 root  wheel  306 Apr  2 10:43 1.4.2
lrwxr-xr-x    1 root  wheel    5 Mar  7 13:57 1.5 -> 1.5.0
drwxr-xr-x    8 root  wheel  272 Jan 31 20:25 1.5.0
drwxr-xr-x    5 root  wheel  170 May 29 09:06 A
lrwxr-xr-x    1 root  wheel    1 Mar  7 13:57 Current -> A
lrwxr-xr-x    1 root  wheel    3 Apr  3 17:17 CurrentJDK -> 1.5


Downgrading WebObjects:


1) I actually backed-up the current WO 5.3.3 version frameworks which  
are required by our project under /System/Library/Frameworks and  
removed them from this location.
2) Copied these frameworks of WO 5.2.4 version from another server to  
this server.


Now the application starts working, though needs to test it thoroughly.


Following are the different frameworks I copied from WO 5.2.4 to the  
server having problem:


1) JavaDTWGeneration.framework
2) JavaDirectToWeb.framework
3) JavaEOAccess.framework
4) JavaEOControl.framework
5) JavaEOProject.framework
6) JavaFoundation.framework
7) JavaJDBCAdaptor.framework
8) JavaWOExtensions.framework
9) JavaWebObjects.framework
10) JavaXML.framework

Thanks & Rgds,

Try to rebuild your app with WO 5.3 and deploy this new build to

Note : WO 5.3 is formally qualified and supported on the Java 1.4.2  
platform only.

Hi Group,


I think now I have a way to Downgrade Java from 1.5.* to 1.4.2  
with the steps provided by Kieran. I'll try this out soon and  
update the group.



I actually checked the .dmg of Mac OS X server I could not find  
anything related to WebObjects...



I am really looking for a nice/safe way to Downgrade WebObjects  
Deployment version on a Mac OS X server from 5.3.* to 5.2.4 .  
Actually, till now I did not find a way to do this...


looking forward to your advises...

Thanks & Rgds,

One question though, do we install WebObjects deployment  
version in a Mac OS X server through XCode or it comes by  
default with Mac OS X server ?



On Server it comes with the default installation, you might  
find the packages on your install CD/DVD for Mac OS X Server.

Thank you for providing steps to DOWNGRADE JAVA, Kieran.


Actually on a development machine, under /Applications/Utilities  
folder we'll be having WebObjects Uninstall scripts. I didn't  
find such scripts in the same location in the Mac OS X server.


Let me check with XCode CD for WebObjects Uninstall script...

Did you check the XCode Tools cd ....... IIRC there might be a  
WOUninstaller script on there ..... I don't have one close at  
hand to check for you, but you could check that.

No Kieran. We actually want to have WebObjects 5.2.4, Java  
1.4.2_09 and Wonder frameworks we had, because our application  
is tested on these versions of software and is stable in these  
versions.

Since you have upgraded this far on that machine, have you tried

Hello Group,


Can anyone guide me how to downgrade WebObjects 5.3.* to  
WebObjects 5.2.4 as well Java 1.5.* to Java 1.4.2_09 ?



We need this ASAP, one of our production server is upgraded to  
WebObjects 5.3.2 and Java 1.5.0_07, and OS is Apple Mac OS X  
10.4.8 and our application is failing to work...



If I run the same application on a Mac OS X server having  
WebObjects 5.2.4 and Java 1.4.2_09, application runs perfectly.



Following is the error in the production server having upgraded  
software:


java.lang.ClassCastException : com.webobjects.eoaccess.EOAttribute

2007-06-06 22:48:21,810 ERROR [admin-FarWest]  
er.extensions.ERXApplication   - Exception caught:  
com.webobjects.eoaccess.EOAttribute



Where does this error occur? in one Custom Class or in the  
WebObject/Wonder Class?


Thanks & Rgds,
Shravan Kumar.M
