No Applications were running after doing full Web Generation in 8.97

Folks,

After installing new OAS 10g R3 on Intel and installing new HTML Server 8.97.1.1 using Server Manager and performing full web generation, I was getting these errors on Screen while running P01012 (Address Book) Program.

""COULD NOT LOAD FORM
Please use the latest Java generator to regenerate the
form.P01012_W4210E_ZJDE0001"

In Jas.log Erors were:

[WARN ] PSFT - [BASE] binary2Object failed desaerializing a byte array java.io.InvalidClassException

After spending some hours in validating the install, I found that default jdk which I was using on generation machine from Websphere Express was not same as what got installed as part of OAS and after copying the JDK from JAS machine to the generation machine the above errors were gone and I was able to run the Applications as desired.

Steps to identify and resolve the issue.

1) On the JAS server navigate to the java directory (e.g. C:\OracleAS_10131\jdk\bin) and run command line : java -version and note the JDK version.

2) On the generation machine navigate to the java directory (e.g. c:\810\system\JDK\bin) and run command line: java -version and note the version.

3) Verify the java version - it must match between the generator and the JAS server.

IF NOT SAME THAN

4) Copy the jdk from the JAS machine to the generation machine i.e. JAS jdk: C:\OracleAS_10131\jdk to generation machine location: C:\e810\system\jdk

5) Truncate the F989999 and F989998 table via OMW -> Table Operation-> Generate Table

6) Launch generator

7) Generate the core objects and a single application (P01012)

8) If successful, execute a full generation.
