Flex Data services not working in Oracle AS or OC4J 10.1.3

[jeffreyjmark]

I followed the instructions in the Install documentation but
still can’t get the Data services to work in Oracle AS or
OC4J 10.1.3. If I try to run Flex Admin I get an RPC fault
“Send Fail, faultcode=client.error.messagesend
faultdetail=channel.connect.fail error netconnection.call.failed:
http: status 500 messageID=2907c199-e9be-8081-c279-423f593a7777. If
I try to run the samples i either get a send fail Error or

1 Exception found.

Exception java.lang.OutOfMemoryError Java heap space.
Increasing the heap size does not help. Does anyone have any
suggestions?

[T__Ruggles]

Do you see exceptions logged at startup?

[jeffreyjmark]

No I don't see any exceptions when OC4J or Oracle AS starts
up

Oc4J start up output:

Would you turn on server and client debugging and retry? The
500 error doesn't give much info to go on.



For client side - add:



<mx:TraceTarget level="0" />



This will add lots of output to the flashlog.txt file. And
for the server side add this to the services-config.xml file under
logging (level="Debug" is key):



<target class="flex.messaging.log.ConsoleTarget"
level="Debug" >

<properties>

<prefix>[Flex] </prefix>

<includeDate>true</includeDate>

<includeTime>true</includeTime>

<includeLevel>true</includeLevel>

<includeCategory>false</includeCategory>

hi,



There is a MBean restriction on oc4j which makes fds fail to
start. Please verify this by requesting the messagebroker servlet!

example


http://localhost:8888/samples/messagebroker/amf

You should see a blank page. If you see a mbean error, it is
the issue which I mentioned.

Workaround: Go to bin/oc4j.cmd or oc4j and edit the java args

set JVMARGS=%OC4J_JVM_ARGS%
-Doc4j.jmx.security.proxy.off=true

I also suggest to increase your heap

set JVMARGS=%OC4J_JVM_ARGS% -Xmx512m
-Doc4j.jmx.security.proxy.off=true

William I added the params to JVMARGS and now I get the
following when OC4J starts



C:\ProgramFiles\oc4j\bin>oc4j -start

and when I try to access
http://localhost:8888/samples/messagebroker/amf

I get the following

Hi,



I have the error and warning too, but the samples work. We
are working on it to provide a fix. By the meanwhile, you should be
able to get fds work. Can you remove the fds samples and redeploy
it? Will get you update if any!

Thanks!

William Chan

[jeffreyjmark]

I removed and redeployed the samples and evrything works now
the only problem now is the OC4J messsage

[aBill]

Hi,



I saw that too. I think it is only happened on 10.1.3.0.0,
not 10.1.3.1 We are also contacting oracle to solve that issue!

Hi,

I have also been having these issues with OC4J.

Did you find out which version of OC4J is needed, and has the
issue been resolved with Oracle?



Many thanks,

Nathan
