Toplink-JAXB Unmarshal problem :SAXPlatform createPlatformDefaultSequence

Hi All,
I'm trying to import some classes (generated by JAXB out of an XSD) into Toplink-Relational project and unmarshal the XML contents. But I get the following exception.

Adding some more information for the same problem.....
I tried to add the sequence like this.. But It doesnt helps..
DatasourceLogin login = (DatasourceLogin)session.getDatasourceLogin();
TableSequence seq = new TableSequence();
seq.setName("OBJECT_EVENT_SEQ");
seq.setTableName("OBJECTEVENT");
seq.setNameFieldName("GUID");
seq.setCounterFieldName("GUID");
login.setDefaultSequence(seq);
Can any one please throw some light into this problem ASAP..?
Thanks

Toplink JAXB - ClassCastException after redeploy in OC4J

Hi,
I'm experiencing an issue casting an unmarshalled object after the application is being redeployed in the container.
I'm trying to unmarshall an xml that I retrieve as a resource from the classloader (the xml is also in the jar)
The ClassCastException is being thrown at the point where I try to cast the unmarshalled object. A sysout on the unmarshalled object prints a classtype that I expect, so my first impression is that the cast fails due the ClassLoader used by the JAXBContext (?) So I've tried to create the JAXBContext with the ClassLoader parameter using the class' classloader directly and the contextClassLoader, both unsuccessfull.
The problem solves after I restart the OC4J container, but for convenience, I would like to solve this without having to restart, if possible.
Has anyone experienced this problem, or know a solution?
Thx!
Bert

Hello Bert,
This is a known issue and there is a patch that is available from Oracle Support. When you contact support please indicate whether you are using TopLink 10.1.3 or 10.1.3.1. Also you can refer Oracle Support to me and I can help them find the correct patch.

JAXB compiler problem in handling xsd:any and nillble = "true"

Dear all,
i am using jdeveloper 10.1.3.1 production release version.
i am designing a xml schema that contain element of attribute nillable="true", for extensible, contain tag <xsd:any>.
but i encounter 2 problem:
1. for xml schema element with attribute nillable="true", no corresponding isNil(), setNil
method is generated (refer to jaxb 1.0 spec. 5.7.1)
2. cannot handle tag <xs:any> that generate incorrect java source code (cannot compile) [refer to jaxb 1.0 spec 5.9.5)
*** i have add jaxb customization tag inside the <xs:any> tag
***   <xs:annotation><xs:appinfo>
***               <jaxb:property name="Extension"/>
***</xs:appinfo></xs:annotation>
Does oracle's JAXB implementation conform to the JAXB 1.0 spec?
Is it a known bug?
Could anybody help me?

Refer to section
E.2 Not Required XML Schema
concepts
"A JAXB implementation is not required to support the following XML Schema
concepts for this version of the specification. A JAXB implementation may
choose to support these features in an implementation dependent manner."
E.2.2 Not supported while manipulating the XML
content
Schema component: wildcard
(any)
how can i know if an xml element with xsi:nil="true" (unmarshal)
and set xsi:nil="true" for an element (marshal) ?
According to the JAXB 1.0 specification:
If {nillable} is "true", the methods setNil() and isNil() are
generated.

JAXB unmarshall problem - beginner

Hi Im having real pain trying to get unmarshall to work with JAXB with a very simple set up..
My DTD looks like
<!ELEMENT CXMLRESULT (MESSAGE)>
<!ELEMENT MESSAGE (#PCDATA)>
and xjs like
<xml-java-binding-schema version="1.0ea">
<element name="CXMLRESULT" type="class" root="true">
</xml-java-binding-schema>
I create an object marshall it and output to a file.. All looks good. This results in the following in the file..
<CXMLRESULT>
<MESSAGE>hello</MESSAGE></CXMLRESULT>
However when I try to read in that file and unmarshall it I run into problems.. Although I receive NO error during the unmarshall, when I do a toString() afterwards then it does not display the MESSAGE element, and similarly trying to validate the object says that MESSAGE hasn't been detected.. I cannot figure out why this is.. The file was written out by JAXB so how come it cant read it back in.. For my unmarshall I do ...
CXMLRESULT cxmlresult=new CXMLRESULT();
try{
try{
input=new File("/in.xml");
fileInputStream=new FileInputStream(input);
} catch (IOException e)
{ System.out.println("error with file"); }
cxmlresult.unmarshal(fileInputStream);
} catch(UnmarshalException e) {
e.printStackTrace();
System.out.println(cxmlresult.toString());
Doing this just shows a CXMLRESULT and not the MESSAGE element..
Any ideas ?
Mark

Try this:
CXMLRESULT cxmlresult = CXMLRESULT.unmarshal(fileInputStream);Dave

Toplink transaction-type problem

we have web application ear file, inside ear file persistence.xml is looking like
<persistence-unit name="TCA" transaction-type="JTA">
<provider>oracle.toplink.essentials.PersistenceProvider</provider>
<jta-data-source>jdbc/TcaConnDS</jta-data-source>
We have deployed same ear file to 4 different oc4j instances and 2 oc4j instances application working without problem. Another 2 oc4j instances application does not work and we have to modify transaction-type="JTA" to transaction-type="RESOURCE_LOCAL" to make it work.
Since we have deployed same ear to all oc4j instances, 2 oc4j only work with transaction-type="JTA" and the other 2 only work with transaction-type="RESOURCE_LOCAL".
I think it is OC4J configuration to affect toplink behavior. Which oc4j configuration can affect toplink transaction-type setting?
Thanks for the help.

Very odd. What does not work, what error do you get?
Are the OC4J servers that same version, what is different about them?

JAXB (XJC) problem with Java 1.4.2_02

Hi,
I am trying to migrate our system to Java version 1.4.2_02 (currently using 1.4.1_02). We use XJC from JAXB to compile XML schema files into java classes. JAXB is packaged in JWSDP (we are using version 1.3). I am currently experiencing a problem whereby if I use java version 1.4.2_02 and run XJC on the xml schema file its not generating any of the inner classes. All classes including inner are generated properly if I am pointing 1.4.1_02.
Just wondering if you came across this problem before and would know of a possible solution.
thanks for your help
Manish

I was having this problem as well. I extracted the MSI from the InstallShield and found that it's looking for a property called "SystemFilesLocked" to equal 1. If you pass it as a parameter and give it a value of 0, this error message doesn't appear. I've installed now to 15 W2K desktops without any issues.
The 'silent installation' documentation for this product is sorely lacking. The install string I'm using is below:
j2re-1_4_2_03-windows-i586-p.exe /S /v/qn"ADDLOCAL=jrecore SYSTEMFILESLOCKED=0 CONTROLPANELLOCKED=1 SKDSILENT=1 IEXPLORER=0 SYSTRAY=0 REBOOT=Suppress JAVAUPDATE=0 JAVAJAVAWLOCKED=0 WEBSTARTICON=0 /L C:\TEMP\LogFiles\JRE_JWS_142_03.log"

Toplink JPA Deployment problem in OC4J

Hi all ,
we are having problem in deployment for an toplink JPA program in OC4J 10.1.3 .. We are using toplink essesntial and our deployed EAR structure is
aaplication.xml
rmwtoplink.war
the content of application.xml is as
<display-name>rmwtoplink</display-name>
<module>
<web>
<web-uri>rmwtoplink.war</web-uri>

</module>
the content of war file as below :
web-inf\web.xml
web-inf\classes\META-INF\persistence.xml
web-inf\classes\<classes>
web-inf\gnf\<jsp pages>
when ever a pages are called those do not use entity manager / jpa call are loading perfectly , but the pages which have used jpa are nt diplayed , we check the error messages , it just halts after following codes :
EntityManagerFactory emf =
Persistence.createEntityManagerFactory(jpaSource);
It seems there is no exception that is even thrown in page or opmn log .
The same program is running fine in Jdveloper 10.1.3 /
Is there any way where we can get the actual error message ?
we are using toplink.jdbc.url for connecting the database .

Here is little more insight for the problem , further check reveals that :

TopLink JPA join problems.

I need a bit of help here, I hope someone can give me a few pointers...
I've been building out an Object Relational mapping in TopLink using the bean-style interfaces. On one of my objects I have a 1:M relationship to another table, so
One Key in T1 -> >1 Keys in T2.
Pretty simple really. I'm doing it like this:
@JoinTable( name=, etc. etc.)
private Set<ObjectForTable2> variableName.
When I call the getVariableName() method, I get back an IndirectSet (as a set) from the method as expected; however, the size of this set is either 0 or 1.
In Table 2 I have approximately a dozen rows which correspond to the join key, and when I run the query toplink is building in my SQL shell, I get back the dozen rows. When TopLink does it, I only get to see the first row. Is there some other trick I need to use with the set returned? Right now when I call mySet.size() on the Set returned from getVariableName() I get a size of 1 or 0. (I only get 0 if I change the key to one that does not exist in table 2.)
if I use the iterator method, such as
for ( final Iterator i = mySet.iterator(); i.hasNext(); ) {
ObjectForTable2 myObj = (ObjectForTable2)i.next();
System.out.println( myObj.getXXX() );
I still only get one result out. Help! What am I doing wrong here? Do I need to configure something to pull back more than one record from the database?
Also, how does one use the Oracle bugtracker for this open-source product, if I don't have a service contract?
Thanks,
Robbie

Exactly.
In TopLink (and in JPA in general) you need identify the field, or combination of fields that are used to uniquely identify entities. As Doug mentioned, it is most common that these fields are the PK of the database.
Based on your response above I assume that you had a non unique field mapped as the PK of the enitity. This could cause the trouble you are experiencing. Mapping the pk to a unique field (or combination of fields) will likely solve this problem.

JAXB unmarshalling problem

Hi
I have a problem with unmarshalling.
when my XML document is valide ,there is no probem but when the document is not valid(for exemple i put a String value in an element of type xs:decimal) i get a strange result:I thought that i will get a java.lang.NumberFormatException when i set the java attribute mapped with that element or i get the error value but this attribute get null as value and there is no NumberFormatException.

SOAP Response Unmarshal Problem

I am using the SOAP Proxy Generator to generate stubs from a WSDL file. This part is okay.
When I use a method in the stub, the runtime generates an exception -- "null". Yes that all it says. I have verified that there is a SOAP response. You can find the actual response text below.
I have traced the problem to the following statement in the generated stub:
<i>perm.unmarshal((SOAPElementImpl) result, container);</i>
Does anyone know if this SOAP response is something that the SOAP client SDK can support?
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" soap:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:ns5="http://www.themindelectric.com/package/com.esri.is.services.glue.v2.mapimage/" xmlns:ns6="http://www.themindelectric.com/package/com.esri.is.services.common.v2.geom/">
<soap:Body>

<maxy xsi:type="xsd:double">35.9999999999999</maxy>
</id1>
</soap:Body>
</soap:Envelope>

I'm afraid the response I incuded earlier in this forum is a "touched" version. I got it by using the response object in the generated stub.
I spoke to the developers of the web service and the response should look like:
<n:getMapResponse xmlns:n='http://arcweb.esri.com/v2' xmlns:ns1='http://www.themindelectric.com/package/com.esri.is.services.glue.v2.mapimage/' xmlns:ns2='http://www.themindelectric.com/package/com.esri.is.services.common.v2.geom/'>

          <maxy xsi:type='xsd:double'>34.1305559999999</maxy>
     </mapExtent>
</Result>
</n:getMapResponse>
Is there a way to get the "actual" SOAP response that was received direct from the web service? What is the official debugging method?

Urgent, Please Help - Toplink & ADF Memory Problem

Hi all,
We are using ADF Rich Client, Toplink11g, Oc4j11g. EJB tier is implementing with SessionBeans using Toplink with Database operations. And BackedBeans for serverside.
Users search records and then update them or create record. For examples user enters cardno in first page and in second page access the user informations. And updates info. Then goes back to first page.
Maybe while going back to first page some toplink objects still referenced with another objects.
i am calling a toplink finder method it returns 10-20 rows and showing on a table these records using method iterator. Users select a row and continue with selected row. At the other page the user modify the data and turn back the search page.
I took heap memory dump of server and i saw that 10 objects in memory.In every search and going edit page this count is increasing. In addition i saw cached objects in memory. There is no problem my toplink cache configuration. But i am not using caching with the other object.
I am just calling finder method in a backed bean,without using table and method iterator there is no object in memory.
Is the problem beacuse of adf pgae life cycle?
I am really in trouble.
Thanks to all.

Go to Menu>Tools>File Manager>Options>Memory details, this will give you a run-down of how much phone memory is free and how much is used, then a breakdown of where the memory is being used. Your phone memory is about 140Mb in total (don't confuse this with the 8Gb - that's just "Mass memory" for storage of data like music, video and pictures plus it is possible to install some apps in there. The phone memory is used for processing as well as sotrage, which is why you get these errors if too much is used.
In the breakdown, you'll see the following items:
- Calendar: this should only be a few Kb, perhaps a few hundred Kb if you use the feature often, but not too much
- Contacts: should also be measured in Kb, even if many of your contacts have images
- Messages: should be measured in Kb, if it goes into Mb or worse still Gb then you have Bluetooth of MMS messages hogging space - save the attachments to mass memory and delete the messages.
- Images, videos and soundclips should not be large - perhaps a small number of ringtones, images that you use as backgrounds etc. but the bulk of these media files are best moved to mass memory.
- Documents should be tiny, keep documents in mass memory.
- MIDP (Java) apps and SIS (Symbian) apps could be filling space, you might be able uninstall some of these and reinstall them to mass memory if needs be, but be aware that some apps must be in phone memory and that some of the space taken by SIS apps will be preinstalled stuff that you can't move.
If none of the above can explain the memory full erros and you do seem to have a large amount of Mb free, then it could be a software issue that can be solved by reformatting the phone with the code *#7370# - make sure that you use PC Suite Content Copier to backup important data first, and after the reformat when you restore the backed-up data, don't include settings in the restoration and also leave out any data types that you know you don' use.

TopLink Proxy Indirection problem when comitting uow

We are trying to introduce the use of TopLink proxy indirection into our object model.
We have run into situations where the uow cannot be committed because proxy indirection is being encountered.
(See the stack trace provided below).
What do we need to be aware of and what actions should we take to make it over this hurdle?
Would ValueHolder cause the same problem, or would TopLink be better able to handle ValueHolder indirection than Proxy Indirection?

Hello,
Could you tell me a little more about what you are trying to do? From the stacktrace it appears that TopLink is searching for all new objects and finding a proxy, and doesn't know that it is uninstantiated.
Could you show me the piece of code where your unit of work registers and commits this object?

Jaxb unmarshal error due to iso-8859-15 character set

I am currently attempting to use JAXB to handle XML unmarshaling. Is there a way to set the encoding used to unMarshall a message to iso-8859-15 as the messages coming in do not have an xml header with encoding specified?

I don't understand. If the XML messages coming in don't specify their own encoding, then their encoding must be UTF-8 or UTF-16. There's no possibility that their encoding can be ISO-8859-15. So why would you want to use ISO-8859-15 to decode them?

JAXB unmarshaling: defaultValue not treated correctly

Hi,
Our XML schema defines an int element with default:
<xs:element name="reconnect-interval" type="xs:integer" default="3600" />
Running JAXB compiler (xjc) on that schema results in an object-tree which
fails to return the pre-set default value when 'reconnect-interval' is not set, as it should.
Looking at the JAXB-generated class which contains this element shows the following:
@XmlElement(name = "reconnect-interval", defaultValue = "3600")
protected BigInteger reconnectInterval;
which I take to mean that the defaultValue was indeed detected by the compiler.
Unmarshaling code is traight forward:
JAXBContext jc = JAXBContext.newInstance( <pkg name> );
Unmarshaller u = jc.createUnmarshaller();;
MyRootElem root = u.unmarshal( new FileInputStream( <xml data file>) );
BigInteger reconnect_interval = root,getReconnectInterval();
// reconnect_interval is null
This is somewhat similr to
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6325871
only that bug is marked solved..
OS: Win XP
Ver: JAXB 2.0 (build 2.0-b26-ea3)
Pls help me figure it out.
Thanks,
Gilad

JAXB-marshalling problem

I am trying to use JAXB for binding. The schema compiler works ok i.e i have got the classes generated but when now when i try to apply marshalling i get an error
Exception in thread "main" java.lang.NoClassDefFoundError: javax/xml/bind/MarshallableObject
could anyone help what could be the problem with this.
Any help is appreciated.
