Re: SDO in Eclipse Plug-in
Hi Tomasz,
What is the SDO version you are using?
Have you tried to debug in the SDO source code to check where exactly it
stops?

I want to make an Eclipse Plug-in that uses Apache Tuscany SDO library.
Unfortunatelly I've come into a severe problem that I can't overcome. I've
tried many different things but nothing has worked and I'm very desperete
for any help.
Here's a description of my problem:
At the moment of calling SDOUtil.createHelperContex() the execution of the
calling method stops. Nothing happens and no exception is thrown.
For example calling of this method causes nothing more than writing
look! on the console:
void exmp() {
System.out.println(look!);
SDOUtil.createHelperContext();
System.out.println(I'm on TV!);
}
A similar problem is with HelperProvider.getDefaultContext().
I suppose the problem is that not all needed libraries are
loaded\initialized as I run the project as the Eclipse Plug-in.
When I used the SDO-Tuscany in application compiled as the SWT Application
everything worked fine!
Is there any way to make the SDO-Tuscany library work in an Eclipse
Plug-in?

Re: Running Tuscany/SCA in Google Android mobile platform
I have started to change the SCA code. Initially, the objects instantiated dynamically were not being instantiated, because info about which class to instantiate is extract from some text files contained in SCA modules' jars. Unfortunately, when Android converter converts the SCA modules' jars to .dex files, it ignores the non-class files, and they are not included. It happens because Android has a very specific way to store the app resources, which is completely different from Java. Though, as Luciano suggested, I started to modify these dynamic instantiation for static. It's working for now : ). All these modifications were made only on host-embedded module code, which I have copied into [1] and renamed to host-android. Also, one of those static instantiated classes was trying to access the javax.naming.InitialContext in its constructor, but it's not supported by Android and I commented the code. As this class belonged to SCA core module, I also copied this module into the mobile-android sandbox and renamed the module to core-android. So, all the modifications made so far are in the [2]. Now, as I was expecting, I got some ClassNotFoundExceptions on SCA code when it tries to use the Java XML API. It happens because Android implements only a small part of this API. So, next step is try to adapt the SCA XML access into Android way to access XML. Does anybody know some other XML API that is javax.xml independent I could use instead of Android one?

I wonder if you've taken a look a the implementation.widget exemplified in the Tutorial demo code? This applies SCA principles to AJAX widgets running in the browser - simplifying the connectivity a great deal (in my opinion) and yet adding little overhead. In the longer run, we may want to look to do something similar for the Android platforms, perhaps with Java rather than the more limited JavaScript components.

Running Tuscany/SCA in Google Android mobile platform
Hi,
Luciano and me have been trying to run the SCA calculator sample on the
Google Android platform, that is a platform for mobile devices. As the
Android platform apps are written in Java language, we tried to run the Java
SCA calculator sample on it.
Although the apps for Android are coded in Java, it's only coded in Java
language. When it's compiled, it generates not .class files, but a file
called .dex, that is equivalent to .jar files. The .dex files are not
compound of Java standard bytecode, but a special bytecode that is intended
to run only on Android VM: Dalvik.
So, in our first try to compile the calculator sample, only importing the
needed SCA jars were not successful, because the SCA jars are compiled using
JDK compiler and do not have the Android special bytecode format.
Fortunately, when you import the SCA jars into an eclipse Android project,
it automatically tries to convert the JDK bytecode to Android bytecode
before execute it. But something was not going correctly yet, cause when it
tries to execute the service I get this exception:
Application Error: com.android.hello An error in com.android.hello. Unnable
to start activity
ComponentInfo{com.android.hello/com.android.hello.HelloAndroid]:
org.osoa.sca.ServiceRuntimeException: java.lang.NullPointerException.
I wasn't sure about what was happening, and then I tried another approach:
not import the SCA jars, but place the SCA source code needed by the
calculator sample into the Android app src folder. This way the SCA would be
compiled directly to Android bytecode.
Unfortunately, the Android is not Java and does not have the entire set of
classes that J2SE provides. It provides only some java classes as java.langand
java.util classes which Android developers kept with the same package/class
names and method signature for easy portability of Java app codes. So, the
common Java classes used on Java SCA were compatible. But, the Java SCA uses
a lot the javax.xml package and Android implements only part of this package
on its platform, so I was getting a lot of errors because the missing
classes that should be contained in this package. I solved it downloading
the StAX source code and JDK javax.xml API source code, and placing it
directly on my Android app project. Finally I got it compiled.
Then, I got another error. I found out that the Android compiler fist
compile the Java code to .class files and then compile the .class files to a
.dex file. The first process everything goes fine, meaning the package
dependencies and code syntax are OK. But on the second process, when it
tries convert the .class files to .dex, I get 4 warnings and 1 error that
are lightly described:

Re: 2 Questions - WSDL deployment and SDO_DAS_XML error
Hi Prashanth, Thanks for your interest in the Native(C++) projects. Sorry, but the SCA is really out of date and its samples weren't updated when DAS for XML was removed. This sample could be fixed using another solution intead of using the php_sdo_das_xml.dll to access data. But I'm not sure which solution, since I'm not used to with PHP. Could you please open a JIRA for it? Maybe you also have already thought about a solution for this problem and submit a patch : ). Tuscany is really needing help with C++ projects.

I can do it invoking dataObject-getDataObject(setting.getProperty()), but if the setting.getProperty() is many=true, I need to use dataObject-getList( setting.getProperty()), however a list of DataObject is returned and not only one, so how can I know which DataObject was inserted on this list?

Re: SDO C++ loading data from XML
Defining via a schema will have created a Type DAS_NAMESPACE#RootType and properties will have been added to this for e.g. Config from the xsd:element name=Config type=config:Config/. Your manual version does not do this. So, when you mean to create a RootType and adding Config as a property, you mean this?: dataFactory-create(DAS_NAMESPACE, RootType); dataFactory-create(DAS_NAMESPACE, Config); dataFactory-addPropertyToType(DAS_NAMESPACE, RootType, Config, DAS_NAMESPACE, Config); I don't quite understand that... I would assume a das user would need the das library! ... but I haven't looked into das a lot so I don't know what the api is or what the user is trying to do here!! DAS framework must be configured before usage, it can be done via code or via xml. Anyway, the DAS needs to read the xml config file to set up the framework. I'm trying to use SDO feature that loads data from xml to retrieve the config info from xml file. The problem is if the DAS to depend on a xsd file to generate the sdo graph structure every time it is executed, so the user will need both, the xsd file and das_runtime.lib :s Adriano Crestani On 6/5/07, Pete Robbins [EMAIL PROTECTED] wrote: On 05/06/07, Adriano Crestani [EMAIL PROTECTED] wrote: Hi Pete, Well, I didn't know about DataFactory operator, but I did it manually, LoL, and it looked like the same when I define using xsd and manually.

I debugged the sdo and look like it defines a DASValue when load using xsd and also sets the rootElementName on DataFactoryImpl. When I define manually I set only the rootElementName, but not the DASValue. I think when the XMLHelper reads the xml it uses this DASValue object set when the xsd is loaded, and that is why I'm saying the xml load NEEDS xsd definition. The DASValue is a way of appending the schema information to the Types and Properties. This should not be necessary in your case but is again a reason to use schema. I will need to look into the SDO code to see what the rootElementName is. I'm not sure what it does but I AM 100% sure you shouldn't set it from a client. You should not need to use any API on DataFactoryImpl (or any.Impl class). The user API is defined in DataFactory.h Above the both methods, manually and using xsd, now complete: Manually: commonj::sdo::DataFactoryPtr dataFactory = commonj::sdo::DataFactory::getDataFactory(); ((commonj::sdo::DataFactoryImpl) *dataFactory).setRootElementName(Config); dataFactory-addType(DAS_NAMESPACE, Table); dataFactory-addType(DAS_NAMESPACE, Relationship); dataFactory-addType(DAS_NAMESPACE, KeyPair); dataFactory-addType(DAS_NAMESPACE, Column); dataFactory-addType(DAS_NAMESPACE, Config); const commonj::sdo::Type table = dataFactory-getType(DAS_NAMESPACE, Table); const commonj::sdo::Type relationship = dataFactory-getType(DAS_NAMESPACE, Relationship); const commonj::sdo::Type keyPair = dataFactory-getType(DAS_NAMESPACE, KeyPair); const commonj::sdo::Type column = dataFactory-getType(DAS_NAMESPACE, Column); const commonj::sdo::Type config = dataFactory-getType(DAS_NAMESPACE, Config); dataFactory-addPropertyToType(table, Column, column, true, false, true); dataFactory-addPropertyToType(table, tableName, SDO_NAMESPACE, String, false, false, true); dataFactory-addPropertyToType(table, typeName, SDO_NAMESPACE, String, false, false, true); dataFactory-addPropertyToType(config, Table, table, true, false, true); dataFactory-addPropertyToType(config, Relationship, relationship, true, false, true); dataFactory-addPropertyToType(config, uri, SDO_NAMESPACE, String, false, false, true); dataFactory-addPropertyToType(relationship, KeyPair, keyPair, true, false, true); dataFactory-addPropertyToType(relationship, name, SDO_NAMESPACE, String, false, false, true); dataFactory-addPropertyToType(relationship, primaryKeyTable, SDO_NAMESPACE, String, false, false, true); dataFactory-addPropertyToType(relationship, foreignKeyTable, SDO_NAMESPACE, String, false, false, true); dataFactory-addPropertyToType(relationship, many, SDO_NAMESPACE, Boolean, false, false, true); dataFactory-setDefault(relationship, many, true); dataFactory-addPropertyToType(keyPair, primaryKeyColumn, SDO_NAMESPACE, String, false, false, true); dataFactory-addPropertyToType(keyPair, foreignKeyColumn
Re: DAS M3 Release
Hi, I've listed the opened JIRAs for Java DAS on [1]. I need a feedback of which JIRA should be resolved before the Java DAS M3 release and which postponed for next one. I will be helping Amita on this research too ; ). I also listed on [1] the JIRAs for Java DAS that were resolved after last release. This list will probably be made the Java DAS M3 key features. Let me know if any feature not listed should be included on or some listed feature should be removed from.

Also, it will really helpful to get your perspective about what all can be the key features, any pending JIRAs which can add value to this release, any must JIRA which need to be newly added. I am going to research too on this front. Appreciate your comments.

Couple things I would like to help for our next release: - Review MySQL Support Sample - Automate creation of Canned databases for DAS Samples (TUSCANY-863) Documentation - Continue to work on DAS User's guide - Migrate it to new wiki and investigate the possibility to add to the release package Infrastructure - Automate release distribution process Once we agree on a set of items for our next release, we then could start tracking the release progress on our wiki. Thoughts ?

Re: Tuscany DAS can't not return static DataObject???
I've never tried to use static names for tables, so sorry, I cannot answer
your first question : (
You may return a user DataObject:
root.getDataObject(User[i]); // where i is a number that defines
the user's position on the users list.

Qestion: if i change List users=root.getList(1) to List users=
root.getList(User); there is not record in the 'users' list,
why?
furthermore, how can I make it return User dataObject, so I
can use user.getUSER_ID() to get the property's value?
Appreciate your help in advance.
