I have a Java compile error which seems to be due to a Java version mismatch. Being unfamilar with Java versioning problems, I would appreciate some help on this, please.
Scenario:
A simple SS project using a Stylus Studio sample XSD (purchaseOrder.xsd); generated the Java binding classes (successful); compiled these Java classes through the SS UI.
The error message (in part) -
---
Main.java
c:\Validation of XML with XSD\StylusStudio\purchaseOrder\Main.java:8: cannot access java.io.FileInputStream
bad class file: C:\Program Files\Java\jre1.5.0_08\lib\rt.jar(java/io/FileInputStream.class)
class file has wrong version 49.0, should be 48.0
Please remove or make sure it appears in the correct subdirectory of the classpath.
import java.io.FileInputStream;
^
1 error

The JRE versions I have installed (under C:\Program Files\Java\ ) are -
JRE 1.5.0_03
JRE 1.5.0_08
JRE 1.4.2_06
Also, I have a JDK (1.4.2_06) installed at C:\j2sdk1.4.2_06\
Does this mean that it is necessary for me to remove the 1.4.2 JDK, and install a JDK version that matches the latest JRE that is installed?
Why I phrase the question this way is that I have just now permitted Sun's auto-downloader to install a patch, which turned out to be a new JRE (1.6.0_01) at C:\Program Files\Java\jre1.6.0_01\
So, should I remove JDK 1.4.2 (and install the 1.6.0_01 JDK), or modify a path (within Stylus Studio) so that the error shown above doesn't happen?
If the latter, how do I do that - and is that on a per-Project basis or is it an option setting in SS?
Attached 22Kb .ZIP contains output from the genration and compilation, the XSD, the .PRJ, and some notes.

Ivan, that is exactly what I couldn't find.
(and I believed it to be fixed immediately, of course.)
I love that autodetection.
I have aligned the versions to 1.4.2_14, closed SS and then restarted.
Checking the Options > JVM after restart, they are exactly as set.
Enable JVM: checked
params: -Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8001
JDK
jvac params: -g
External JVM
parms: blank
Debugging params: -Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=${AutoDetect}
So that looks right.
But now I have another error.

That just does not make sense to me. I expected alignment of the JVM (JRE) and the JDK would generate code OK, and then I could just compile that (ie, that the compiler would accept it).
What I find is that code generation fails with JVM (JRE) 1.4.2_14.
However, the code generation WILL succeed if the JVM version is set to something higher than v1.4.2_14 - I set it to the highest I have installed, which is 1.6.0_01 (when I started this thread I had JRE v1.5.0_08 installed, and the JDK that I installed was 1.4.2_06).
My current available JRE versions are shown in an attachment.
I removed JDK 1.4.2_06 and installed JDK 1.4.2_14. That is the only JDK I have installed.
OK, I got the code genrated. Next, see if that will compile.
So, I set the JVM (JRE) and the JDK to align at 1.4.2_14 - and quit / restarted SS, then ran the compile on Main.java.
Now the compilation succeeds.
The ZIP attached contains code generation output messages -
Generate4.txt (failed, JRE was 1.4.2_14)
Generate5.txt (succeeded, JRE was 1.6.0_01)
compilation output message -
Compile5.txt (succeeded, both JVM and JDK aligned to 1.4.2_14)
also screenshots of the Options > Java Virtual machine settings.
This doesn't make sense to me.
