[JBoss JIRA] Created: (JBREM-692) Let marshallers/unmarshallers construct their preferred streams.
by Ron Sigal (JIRA)
Let marshallers/unmarshallers construct their preferred streams.
----------------------------------------------------------------
Key: JBREM-692
URL: http://jira.jboss.com/jira/browse/JBREM-692
Project: JBoss Remoting
Issue Type: Feature Request
Security Level: Public (Everyone can see)
Affects Versions: 2.2.0.Beta1 (Bluto)
Reporter: Ron Sigal
Assigned To: Ron Sigal
Fix For: 2.2.0.Beta1 (Bluto)
In response to JBREM-597 the socket transport was changed to provide raw socket streams to the marshaller layer. This leads to several issues:
1. JBREM-623
2. JBREM-631
3. The result of JBREM-597 is that (un)marshallers like Serializable(Un)Marshaller that use object streams need to recreate object streams with each invocation, which is time consuming.
A solution, suggested by Tom Elrod, is to allow the marshaller layer to construct the streams it prefers to work with, which can then be cached at the transport layer.

[JBoss JIRA] Created: (JBRULES-592) Problem with WorkingMemory serialization
by Edson Tirelli (JIRA)
Problem with WorkingMemory serialization
----------------------------------------
Key: JBRULES-592
URL: http://jira.jboss.com/jira/browse/JBRULES-592
Project: JBoss Rules
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: Reteoo
Affects Versions: 3.0.5, 3.0.4, 3.0.3, 3.0.2, 3.0.1, 3.0
Reporter: Edson Tirelli

Fix For: 3.1-m1, 3.0.5
REPORTED BY MICHAEL SUZIO:
-----------------------------------------------
I've run into a problem. Strangely enough, I swear this worked in the past, but then we went into a long coding phase and emerged from it to find out our test cases didn't actually work "in the wild". Took some time, but eventually I figured out the why of that -- and coded better tests.
In any case, here is what is happening:
- We create a rulebase from some DRL text (doesn't matter how it gets created, my test code below is *one* example case)
- A Working Memory object is created:
WorkingMemory wm =3D3D3D rulebase.newWorkingMemory();
- The WorkingMemory is serialized to disk via normal ObjectOutputStream methods
Now, *while the VM is running*, I can create new RuleBase objects, read that WorkingMemory back in, and attach it to those new RuleBase objects, and it always works. However, if I stop the VM, and re-run the sample program below, it fails with this stack trace:

So, it appears that WorkingMemory objects cannot (at least for me in this case) be serialized, then read back into a new VM. That always fails, and it's quite vexing. Our intention is to be running rules on large amounts of data that periodically come in, and we need to save our progress as we go along and be able to restore that data anywhere in the data cluster that the job gets parceled out to (so, ultimately, the WorkingMemory data is going to go into a database or possibly get written out to a shared filesystem among the drones). If I can't save/restore data transparently between runs, this is pretty much a show-stopper.
Technical details: Java 1.5.0_10 (but I tested this on 1.5.0_04, 1.5.0_06, 1.5.0_08, and 1.5.0_09 -- basically, whatever we had available on other people's workstations), all on Windows boxes. JBoss Rules 3.0.3 and 3.0.5 both seemed to fail consistently.
Here is the sample code (it's two classes, save them to appropriate files). I think these should be reproducible cases. Run the DroolsFailureTest twice, and it will work the first time (showing that reads/writes within the VM work), and then fail the second time it is run (when the cached WorkingMemory on disk then is getting read back into a new VM).

In fact, it looks like my problem is just a variant on Raffael's. Like Raffael, I've tried JBoss 3.0.5 (no help) and Java 1.6 (similar results
-- different "stream corrupted" error in my case, but essentially the same). I don't see a resolution to his bug on the archives -- Raffael, did you find a fix? Please let me know!
Sorry for such a long post, but I hope someone can point out what I can do to fix this issue.
