JAXB class conflict error

I am new to JAXB.
I am using external customization file to create JAXB classes.
I have one XSD file which includes another XSD. Both of them have the same element name and the classes are getting created in the same folder. I have tried each and every option of the options mentioned in the fix collides examples of JAXB sun tutorial without any success.
Please guide me on this.
This is the following error:
compile:

This is because of name conflicts in the xsd. If the <xsd:element> name is same as some <xsd:complexType> and that is referenced from the element this happens. If you provide different names, it will solve the problem

Class conflicts with third-party libraries on j2ee engine

Hi,
I am deploying a repository manager into EP. In my repository I referenced javax.xml.namespace.QName, which conflicts with the one declared in jaxrpc.jar in j2ee/cluster/server0/bin/ext/webservices_lib.
I am not very clear about how NW j2ee engine loads classes, but it seems that it loads classes in j2ee/cluster/server0/bin/ext/webservices_lib first. As a result, I got a class confliction error:
java.lang.NoSuchMethodError: javax.xml.namespace.QName.<init>(Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;)V
If I remove QName.class from the jar in webservices_lib, it works fine, but this not the right way. I have read Note 990854, but not clear about how to do. Could anyone give any help?
Thanks,
Ray

Close this thread as it makes little sense.

Class conflict upon import

I've got the most ugly sub VI ever created (not by mysself) that I've been tasked with maintaining and upgrading. It's a quagmire, but it's a quagmire that works with a couple minor exceptions. It was written using LabVIEW 7.0. One of my todos is to make it work under Windows 7. To that end, plus several bug in LabVIEW 7.0 which are well past the point of expecting anyone to maintain, I've tried to import it into LabVIEW 2010. I have one "Wire: Class conflict" errors upon the automatic upgrade that I can't figure out how to resolve. It is a reference to a tab control that is wired into an Insert into Array VI.
Detail: You have connected a refnum of one type to a refnum of another type and both types are members of some class hierarchy, but there is neither a simple up cast nor type cast between the two classes.
Warning: the attached VI is the worst of a collection of what-not-to-do VIs I am dealing with. I'll remove it as soon as I resolve this issue, due to sheer embarassment.

I figured it out myself.
1. Create a constant to the Insert Into Array VI
2. Use that constant as Target Class to To More Specific Class VI
3. Use the original property node as reference to To More Specific Class VI
4. Disconnect the constant created in step #1, connect the output from To More Specific Class VI
Huh, no edit nor delete on the original post. Oh well.

Adding tab to typedef tabcontrol causes class conflict with global variable

Hi,
I am quite new to labview. I have to update an existing program and I have a problem whith a tabcontrol. In attachement, I give you a very simple solution showing my problem.
I have defined a simple tabControl in a typedef ctl. I had it to a VI and in block diagram of this VI, I want to fill a global variable with this control and this global variable is set as "Include Data Type".
When creating my ctl file with a simple tabcontrol, there is no problem but my tabcontrol only contains 2 tabs. When I use "Add page after" in my ctl file to create a third one, after saving, I get a class conflict error on wire to global variable in my block diagram.
If I remove added page, all is OK again. I don't understand why adding a new page causes a class conflict. In my attachement, it is very simple but in program that I have to modify, I already have 15 tabs and I just want to add a 16th one so, I am sure there is a mean, but impossible to fond it after many hours...
If someone can tell me how to make my example works with "Include Data Type" (if I remove it, it always works but that is not what I want) and adding an additional tab, it would hemp me a lot!
Thanks in advance.

The problem is that the tab is an enum, and you can't wire two strictly typed references of two different enums together, because they are considered different data types. What you can do is right click the reference control in the global variable and select Show Control, which will show the data type of the reference. You can then replace the control inside the reference with the typedef, which will cause it to update correctly.
Although that will solve the problem, if you have the reference to a tab control in a global variable, you probably have some issues with your code, but that's not something which can be commented on without more details.

I created boolean references in my main vi block diagram and copied them to my sub vi front panel. when wire my reference in my main vi to one the input node of the sub vi the wire is broken. the error says its a class conflict why?

i created boolean references in my main vi block diagram and copied them to my sub vi front panel. when wire my reference in my main vi to one the input node of the sub vi the wire is broken. the error says its a class conflict why?

Expanding and clarifying what BJD said;
After you create the temporary sub-VI that BJD mentioned, open its front panel and copy the reference control that LV created when it created the sub-VI.
This reference control will be correct class etc that you need. Use the control to replace the original control that you were attempting to wire up.
The technique of "create sub-VI...copy" always works for me.
There is one more thing that you should watch out for.
The mechanical action of the boolean can not be set for latch action when attempting to read the value using a value property node.

Type conflict error for method of a class

Hi all,
I am getting a type conflict error in method Read of class CL_SWF_REP_ITEM2OBJECT, the error text is
"A type conflict occurred when the program tried to passan actual parameter to the formal parameter 'EX_WI2OBJ_WIHDR' of the method 'READ' of the class'CL_SWF_REP_ITEM2OBJECT'."
I am calling this method from the FM SAP_WAPI_WORKITEMS_TO_OBJECT. I have checked the type and other things and they all seem fine. Funny enough, all the culprits in question are sap standard objects.
Also the same methods and FM work fine for 4.7 and release 640 of Ecc6.0, however doesnt work for release 700 of ECC6.0
kindly guide

Hi,
If the method is:
'Instance Method' use -> to refer to the method of the class
If the method is :
'Static Method' use => assignment to refer to the method.
Could you specify the class and method details so that if the error can ba analyzed.

Duplicate class definition error while invoking EJB from ADF project

Hi,
I am using Jdeveloper TP3 and facing the following problem.
I have built an EJB project and am ran them successfully in the embedded OC4J via a standalone java program.
Now I created another project with ADF capabilities and when I tried to ping the EJB i get the following exception
The application named, current-workspace-app, could not start due to an error.
duplicate class definition: javax/faces/context/FacesContextFactory Invalid class: javax.faces.context.FacesContextFactory Loader
This is happenning due to class conflicts between javaee.jar and trinidad-impl.jar/adf-richclient-impl.jar.
Is there any way of bypassing this class loader issue?

Hi,
actually I didn' try the JNDI lookup but used resource injection instead
In a JSF managed bean I use
@EJB Ejb30SessionFacadeLocal myLocalInterface;
public SortableModel getTableModel() {
List rows = new ArrayList<Employees>();
rows = myLocalInterface.queryEmployeesFindAll();
this.tableModel = new SortableModel(rows);
return tableModel;
Its a EJB 3.0 session bean that accesses a Local interface. However, if the remote is on the same server then I would think that using @EJB Ejb30SessionFacadeRemote myRemoteInterface; does similar

Cannot Use JaxB classes in ADF application.

Hi
I am using JDeveloper 11.1.1.6
I am trying to call the Oracle Business Rules (OBR) Ruleset from the frontend.
When I call a simple rule only using Java facts (facts are object references of classes which are used in OBR) as input, the Rules are verified and executed correctly.
After that I tried to give XML Facts as input the application is facing ClassNotFoundException.
To access the XML facts I had to add the XML Fact class known as JAXB_CLASSES into the Libraries and Classpath of Project Properties.
First I tried to call the OBR rules containing the XML Facts / Jaxb_classes from the page and it throwed ClassNotFoundException while deploying the application.
Next I tried to invoke the Jaxb_classes from main method and it worked fine.
My Question is : How can I access JAXB Classes in an ADF View Controller Project/ Application?
Thanks,
Nigel.

I am adding the JAXB_classes into the application in the Backend and the code for intialising is also written in the Backens.
Still, the application is throwing a exception like
<RuleSession> <logIt> The symbol 'generated.ParametersType' is undefined.
at line 7 column 14 in main
<RuleSession> <logIt> UndefinedException: The symbol 'generated.ParametersType' is undefined.

The web service project will add additional server runtime libraries to the classpath thus resolving the jaxb dependencies, in the case of a dynamic web project, you'll have to manage that with the JPA facet and eclipselink, or by adding the Moxy jars seperately. However, if you want to use the target runtime libraries create a user-library and reference the following server libraries: (from Server Install Dir\modules) glassfish.jaxb_"version".jar, glassfish.jaxb.xjc_"version".jar, javax.activation_"version".jar, javax.xml.bind_"version".jar, javax.xml.stream_"version".jar.

Wire: class conflict in LABVIEW 7.0 Express

Hello all,
recently, we were upgrading from LABVIEW 6i to LABVIEW 7.0 .
Everything seems to be finde with one exception.
In a VI I use an intensity graph (three dimensional graph). The change
of its properties, in particular some values affecting the intensity
display, is done in a SubVI.
This SubVI gets a reference to the intensity graph as handle. The
corresponding terminal in the SubVI is a RefNum control.
In LABVIEW 6i this was working without any problems but in LABVIEW 7,
it does not work anymore.
I get a broken wire sign (red cross) and the error message
Wire: class conflict .
The online help did not bring much light into that situation. There is
only a somehow hidden hint that the options for the RefNum control
sh
ould be checked.
But what is really wrong there? Should I use anything else as terminal
in my SubVI or is there a particulkar option that needs to be set?
At the moment, the VI server class of the RefNum control is set to
Generic|Generic|Object|Control|Graph|IntensityGraph (copied from mind
at the moment).
Any hints would be greatly appreciated.
Thank you very much in advance and best regards
Gerd

Hi Gerd,
I have had problems in the past with passing control references into subVIs. I had these problems because the strict control reference is often incompatible with a non-strict refnum control, or a strict refnum control of the wrong type. For example, if you have a multi-selection listbox, but you try to wire that control reference to a listbox reference associated with a scalar datatype (single-selection), you will get a wiring error.
The easiest solution for these problems is to right-click on the control reference and choose Create > Control. Then, copy this control into your subVI and use it as the subVI input. I think this will solve your class conflict problems.
If this doesn't work right, let me know and we can talk further...attachi
ng a sample LLB that demonstrates the problem would be helpful.

Class Conflict On Object Wires

Does anyone know why I get a class conflict when doing the below:
All of the above objects desend from a common ancestor.
I can fix it doing this:
Is this the correct way to get around it? Do I lose the child specific member data when I recast it as the more specific class?

You can see that not all classes inherit from BRSIGHT, because there's a coercion dot on all inputs going into the build array primitive. If they all inherited from it, then the first terminal would not have a coercion node.
In the specific case of the code you show, this works because the first element (which is the one you take) IS a BRSIGHT, so casting it returns no error. If it wouldn't be a BRSIGHT, you would get an error out of the cast and a default BRSIGHT object. It's important to understand that the cast node doesn't change the object - the object always carries all of its data, regardless of the type of the wire it's on. Casting only changes the type of the wire, but the actual object on the wire has to be of the same class as the object wired to the type terminal.

Error building project using kXML2 - "Class loading error: Wrong name"

Hi,
I'm testing the XML-Parser KXML2 and downloaded the latest package, but the minimal version (kxml2-min.zip). I put this file into the directory "%j2mewtk%\apps\KxmlTest\lib" and wrote the lines
import org.kxml2.io.*;
import org.xmlpull.v1.*;
When I try to build the project with the Wireless Toolkit (v1.04) it spits out the following error:
Error preverifying class kxml2.io.KXmlParser
Class loading error: Wrong name
com.sun.kvem.ktools.ExecutionException: Preverifier returned 1
Build failed
I also tried the full package "kxml2.zip" but the same error occurs.
How can I get rid of this? Thanks in advance!

Okay, finally worked it out (hopefully). I unpacked the archive to a directory (say "%J2MEWTK%\apps\KxmlTest\tmpclasses") and then preverified them "manually":
%J2SDK%\bin\preverify.exe -classpath "%J2MEWTK%\apps\KxmlTest\tmpclasses";"%J2MEWTK%\lib\midpapi.zip" org.kxml2.io.KXmlParser
%J2SDK%\bin\preverify.exe -classpath "%J2MEWTK%\apps\KxmlTest\tmpclasses";"%J2MEWTK%\lib\midpapi.zip" org.xmlpull.v1.XmlPullParser
%J2SDK%\bin\preverify.exe -classpath "%J2MEWTK%\apps\KxmlTest\tmpclasses";"%J2MEWTK%\lib\midpapi.zip" org.xmlpull.v1.XmlPullParserException
Then I packed them again to a jar-file:
%J2SDK%\bin\jar.exe -cvf kxml2-min.jar %J2MEWTK%\apps\KxmlTest\tmpclasses\output\.
That was all!

Why do I get a class conflict between the Prepare SQL.vi and the Get Column Name.vi with the SQL Toolkit compatibility vis from the Database Connectivity Toolkit?

I have done extensive programming with the SQL Toolkit with LabVIEW versions through 6.1. My customer now wants to upgrade to Windows 7, so I am trying to upgrade to LabVIEW 2009 (my latest purchased version) using the Database Connectivity Toolkit, and the SQL Toolkit Compatibility vis. Everything seemed to be going okay with the higher level SQL operations, but I ran into trouble with the Get Column Name.vi.
The pictures below show the problem. The original SQL Toolkit connected the Prepare SQL.vi with the Get Column Name.vi with a cluster of two references, one for connection, and one for sql. The new compatibility vis have a class conflict in the wire because the Prepare SQL.vi contains a cluster with connection, and command references, but the Get Column Name.vi expects a cluster with connection and recordset references.
How do I resolve this conflict?
Thank You.
Dan

I've never worked with the old version of the toolkit, so I don't know how it did things, but looking inside the SQL prep VI, it only generates a command, and the the column name VI wants a recordset. I'm not super familiar with all the internals of ADO, but my understanding is that is standard - you only have the columns after you execute the command and get the recordset back. What you can apparently do here is insert the Execute Prepared SQL VI in the middle and that will return what you need.
I'm not sure why it worked before. Maybe the execute was hidden inside the prep VI or maybe you can get the column names out of the command object before execution. In general, I would recommend considering switching to the newer VIs.

Assign Type conflict error

Hi,
I am trying to load the data from PSA to write optimised DSO in production and it is throwing me an error 'Short dump :Assign Type conflict error".
I have no routines in the transformations.Source data types are matching with target data types.
Is there any way I could resolve this issue.
Thanks,
Chandra

Hi,
I had this problem when i was loading the sales cube. the problem was UOM was not maintained in the system. Then I maintained UOM in the bi and solved the issue. JUst check if your data from the source has got the master data in bi.

Add-on Conflict error while installing add-on LOCIN release 100

Hi experts,
I want to install the add-on for India Localization for IS-Utilities i.e., LOCIN release 100. I have downloaded the add-on and also the CRT(SAPK-10001INLOCINISU) required for the add-on.
we got an error while installing the add-on it is
"OCS package SAPK-10001INLOCINISU does not match the current software component vector"
if we remove the CRT from the queue and start the installation then it will give add-0n conflict error.

Hi,
I had somthng like this recently with SCMEWM....
1. Clear out your EPS/in directory
2. Download the latest version of the add-on and all the patches ===> the latest CRT's will be in the patches.
3. Unpack them and try import again.
