Does Tuscany support jaxws implementation?
Hi all I create a web service using stp jaxws project, and now, I want assembly these services as using sca components, I wondered if Tuscany supports jaxws service as its implementation. I am trying to create a sca component in composite file by following MikeEdwards's article in OSOA which url is http://www.osoa.org/display/Main/JAX-WS+Services+Integration. Does Tuscany know the tag "implementation.jaxws" Thanks Denny
Re: An update collision occurred when update the primary key property !
UpdateGenerator forms update statement with "where" clause like this - iterate over all PKs and include them in "where" clause. Then iterate over all changed fields and include them in "where" clause with values set to old values from change summary. In case the PK itself is being changed, this results in something like below - update tableX set idX=? where idX=? and idX=oldValueOfidX Later in ChangeOperation.execute(), when the changed fields in DObj are scanned referring to propertyNames,for idX, the new value is found and set for both idX params above with "?", this is because the first "where" clause idX is not marked as Collision param. This results in - update tableX set idX=newValueOfIdx where idX=newValueOfIdx and idX=oldValueOfidX This results in 0 rows update in DB and seen by DAS as OCC Exception. A simple fix will be - when changedFields includes a PK, avoid first inclusion in where clause in UpdateGenerator. For other cases (i.e. changedFields do not include PK), keep the logic as is. There can be cases where the PK needs to be modified in the tables - like data migration, system upgrades etc. So the above simple fix will be useful in supporting update of PK. Old discussion ref - http://www.mail-archive.com/[EMAIL PROTECTED]/msg16310.html Minor change on the top of the above discussion is making update efficient by avoiding duplicate inclusion of same column in "where" clause. New test case - AliasTests.testModifyPK() Submitting patch soon for this.

Re: Does Tuscany support jaxws implementation?
Hi Denny, We don't have this support in Tuscany currently. I think it would be good to add it. I have been doing some work recently to provide better support for JAX-WS semantics in the Tuscany implementations of implementation.java and binding.ws, but this is not the same as what's described in the article. However, this code should be reusable as part of the work to support implementation.jaxws components. For example, the fix for TUSCANY-1939 adds data binding support for the default JAX-WS mapping of thrown POJO exceptions. Are you interested in helping with adding support for implementation.jaxws components in Tuscany?

Re: web service problem (and configuration)
I don't think you can pass or return an interface type across
the Web Service binding, only a class type.
This is a rather nasty limitation. I believe there is some deep
JAXB magic ("factory" annotations) that could work around this
limitation, but I haven't got far enough into this to know how
to use it or whether it currently works in Tuscany.

hello,
this is an example that shows the problem.
listSalePointCodesOA and listSalePointCodesIA return an array and works
well, but listSalePointCodes return a List and have the commented
problems.They are defined in.Services and implemented in
ServicesImplementation.
Runner is the class that start the application.
The web services are published in http://localhost:8887/Services?wsdl.
thanks,

When I want to return a collection of elements, if I use a List type the

service invocation return only 2 elements of the list (when I use

I suppose the problem is in the implementation of the web service with

all the elements of the List?

Re: Does Tuscany support jaxws implementation?
Hi Simon I would like to add support for implementation.jaxws components in Tuscany, but for now , I have been working on Eclipse STP project and have to spent more time on the project for next release. I'm very interested in Tuncany and very pleasure to contribute to it when I have more time. So far, in my project, I am trying to assemble jaxws services into SCA components and run with tuncany, do you have any suggestions on how to create sca components with jaxws implementation? where can I get a sample about it?
