Re: binding RMIDispatcher to client
HELP!
I've been running into the same problem as what was reported in this thread
before. When attempting to run a RMI client I get the exception:
org.ofbiz.service.rmi.socket.ssl.SSLClientSocketFactory; local class
incompatible: stream classdesc serialVersionUID = -6771263703492769955, local
class serialVersionUID = 2417260480409974286
at sun.rmi.registry.RegistryImpl_Stub.lookup(Unknown Source)
Hopefully this has been resolved by someone?
Thanks!
John
Here's my steps:
1. clean build of the application server: ant build (command line)
codebase: ofbiz_opentaps_424208
WindowsXP
java 1.4.2
Eclipse 3.1
2. Copied the following jars into my classpath:
ofbiz-base.jar
ofbiz-entity.jar <--- There were some dependencies found in this jar
ofbiz-service-rmi.jar
commons-collections.jar
javolution.jar
jdbm.jar
log4j.jar
NOTE: I had to add a line to the ofbiz-service-rmi.jar (rmi-jar) build.xml
script because there were a bunch of references into the org.ofbiz.service
directories not getting pulled in.
<fileset dir="${build.dir}/classes" includes="org/ofbiz/service/**"/>
3. start application startofbiz.bat
4. In Eclipse, run the RMI Client Example.
When I attempt to execute this line:
rd = (RemoteDispatcher) Naming.lookup(RMI_URL);
I get the following exception:
java.rmi.UnmarshalException: error unmarshalling return; nested exception is:
java.io.InvalidClassException:
org.ofbiz.service.rmi.socket.ssl.SSLClientSocketFactory; local class

Hello,
http://java.sun.com/j2se/1.5.0/docs/api/java/io/Serializable.html
"However, it is _strongly_recommended_ that all serializable classes
explicitly declare serialVersionUID values, since the default
serialVersionUID computation is highly sensitive to class details that
may vary depending on compiler implementations, and can thus result in
unexpected InvalidClassExceptions during deserialization."

One trick with this: it is a good temporary fix, but not something I
think we'll do in the project because it is tough to remember to
manually change it each time the fields (or the data structure in
general of the class) change.

FYI,
Another quick fix to the RMI serialization problem is to explicitly
define the serialization constant, serialVersionUI. Then it doesn't
matter if the code was compiled outside of eclipse (i.e. Ant for
ofbiz) or inside eclipse for your RMI test client.
For example:
private static final long serialVersionUID = -6978458356505526156L;
This may be impractical to do for every serializable class in ofbiz
but it does work on a case by case basis.

For that in Eclipse you may use Windows/Preferences/General/Workspace : "refresh automatically"

Re: binding RMIDispatcher to client

if you put the library paths in the project you need to do a refresh
after a build. this is to resolve unsatisfied links in the project paths.
like the simple method of inserting debug info code when I want to see
something.

Re: binding RMIDispatcher to client
Posted by Brett Palmer <br...@gmail.com>.
That would be nice to include an eclipse project to do this. One
problem with item 2 is if you depend on the build/lib/*.jar files
these will be continually deleted by Ant. This will give you errors
in eclipse. And in some cases you want be able to run an Ant clean
while eclipse is loaded since it will have a handle on those libraries
and the ant clean target will ffail.
To do it right, you probably need to copy the build libraries into an
independent directory specfically for RMI client stuff (and then be
aware of dependencies when the code changes).

Hi
I wonder if we can, and if we should do step 2 at a project level to
avoid this problem in the future...

Re: binding RMIDispatcher to client
Posted by Brett Palmer <br...@gmail.com>.
John,
Yes this is a problem with trying to run the RMI client in the Eclipse
debugger. I believe the problem occurs because ofbiz is compiled
using Ant and is not being compiled by Eclipse. Then when you run the
RMI client within eclipse you get an incompatibility because the RMI
client is using all the ofibz code that is in eclipse. Does this
make any sense? Running Ant within eclipse won't help either because
I believe the is still compiling outside of eclipse.
There are a couple ways to work around this problem. The first one is
the easiest and the second is more tedious.
1. Create a simple script that executes the RMI client application. I
am assuming that you are really trying to debug an ofbiz service and
not the RMI client itself. Then with Eclipse create a remote debug
session with the server and set your break points in the server code
you want to debug. When the RMI client request hits the server the
debugger will stop at your break point.
Your script will need to include all the necessary Jar files to work.
I will include a sample at the bottom of this E-mail. You usually
have to tweak the classpaths a little but once everything is working
you can easily debug server side code using RMI.
2. Another approach would be to create an eclipse project that
contained all the ofbiz built Jar files that were necessary for RMI
communication. Then server libraries would match with the client
libraries.
Does anyone else have an easier solution?
