Problem with Persistence.xml in JDev final after migration

Hi,
I am trying to migrate a current project from JDev 11gTp4 to the JDev production release. When deploying the EJB module I get the following problem though (Stack from DefaultServer.log)
weblogic.application.ModuleException: Exception preparing module: EJBModule(Nexus-NexusModel-ejb)

I have noticed that the persistence.xml file have changed quite drastically from the version we had in TP4 release during project upgrade, but can not explain the problem we are getting. I have also tried to just create a dummy project and create a persistence unit, and the file looks exactly the same afterwards. Any thoughts?
Drikus

Just thought I would add a temporary solution to the problem for those of you sitting with the same issue.
In the root folder of your application you will find a src folder with a meta-inf folder and weblogic-application.xml inside.
Add the following before the closing weblogic-application tag...
<xml>
<parser-factory>
<saxparser-factory>
weblogic.xml.jaxp.WebLogicSAXParserFactory
</saxparser-factory>
<document-builder-factory>
weblogic.xml.jaxp.WebLogicDocumentBuilderFactory
</document-builder-factory>
<transformer-factory>
weblogic.xml.jaxp.WebLogicSAXTransformerFactory
</transformer-factory>
</parser-factory>
</xml>
If there wasnt an xml tag in the file, it seems that JDeveloper somehow adds one on the fly for you pointing to an oracle xml parser that does not contain the setSchema method required by weblogic on deployment.
Hope this helps anybody else that has this problem.

Problem with date format parameter in SSRS2012 after migration from SSRS2008

Hello,
We are migration from
Reporting Services 2008 on Windows 2008 server
to
Reporting Services 2012 with Always On on Windows 2012 server.
I have a report that expects a date in the querystring: "...&DateTo=17/09/2014"
This use to work in the previous environment and now fails !
I logged onto the server with the credentials that runs SSRS and changed its regional settings to French(France): It didn't helped.
I tried passing in the date otherwise "...&DateTo=09/17/2014": it worked !
I tried changing the regional settings in my IE and it worked but that can't be a solution... it is still working on my Windows 2008 server... unless there is a statement from Microsoft that it explains that now it works only like this but I would be surprised... is it ?
I also saw that changing a directive in the web page can help but, why did it stopped working, is it the handling of a default value for regional settings that changed in SSRS ?
I would need help to understand this, thank you for any help you can provide.
Regards,
Claude VERNIER

Hi Claude,
Based on my research, SQL Server doesn’t supports DD/MM/YYYY date format. When we insert “17/09/2014” value in a date type column, it pops up an error message that “String was not recognized as a valid DateTime”. It means that the value “17/09/2014” is acted
as “2014/17/09” string. So in your scenario, we cannot get the expect results.
To work around this issue, we should change it to “09/17/2014”.

If there are any other questions, please feel free to ask.

Problem with generating xml and nested cursor (ora-600)

I have a problem with generating xml (with dbms_xmlquery or xmlgen) and nested cursors.
When I execute the following command, I get a ORA-600 error:
select dbms_xmlquery.getxml('select mst_id
, mst_source
, cursor(select per.*
, cursor(select ftm_fdf_number
, ftm_value
from t_feature_master
where ftm_mstr_id = pers_master_id ) as features
from t_person per
where pers_master_id = mst_id ) as persons
from f_master
where mst_id = 3059435')
from dual;
<?xml version = '1.0'?>
<ERROR>oracle.xml.sql.OracleXMLSQLException: ORA-00600: internal error code, arguments: [kokbnp2], [1731], [], [], [], [], [], []
</ERROR>
The problem is the second cursor (t_feature_master).
I want to generate this:
<master>
<..>
<persons>
<..>
<features>
<..>
</features>
</persons>
<persons>
<..>
<features>
<..>
</features>
</persons>
</master>
If i execute the select-statement in sql-plus, then I get the next result.
MST_ID MST_SOURCE PERSONS

CURSOR STATEMENT : 3
PERS_MASTER_ID PERS_TITLE PERS_INITI PERS_FIRSTNAME PERS_MIDDL PERS_LASTNAME

CURSOR STATEMENT : 15
FTM_FDF_NUMBER FTM_VALUE

10 ....
I use Oracle 8.1.7.4 with Oracle XDK v9.2.0.5.0.
Is this a bug and do somebody know a workaround?

Very simple...Drop all type objects and nested tables and create them again. You will get no error. I'll explain the reason later.

Problems with System Update 3.14.0019 after installation SP2

Have you encountered problems with System Update 3.14.0019 after installation SP2 for Windows Vista?
After this upgrade I view this error: "An error occurred while gathering user information."
Thanks for the help

A known issue. It wasn't supposed to be supported until SP2 is RTM. However, look at the stickied post in the forum for some bad news about SU.

Problem with the XML in Word 2007 (Word Template)

Hi Experts,
i am new on CRM 2007 and i have a problem with the XML Structure of the Word Template.
First i built a Web Service Design Tool. Then i saw on the Testpage, that it works.
So i started the Document Templates and created a new Template. Object Type was BUS2000126 - CRM Business Activity. Web Service was my created and tested Web Service Tool.
As i opened the Word 2007 with the XML-Structure, i recognized, that there was something wrong.
The Responce on my Testpage from the Web Service Tool had the following structure:
response (test.types.p1.CrmostZlaWord5ReadResponse)
   Output (test.types.p1.CrmostZla010RoszlaWord5001)
        ZlaWord5 (test.types.p1.CrmostZla010Rosbtorder)
            Administrativeheaderoforder (test.types.p1.CrmostZla010Rosbtorderhea001)
                 Partiesinvolvedofheader (test.types.p1.CrmostZla010Rosbtheaderpa001)
                     Allpartiesinvolved (test.types.p1.CrmostZla010Rosbtpartnera002[]) Displaying 3 elements of 3
                          element1 (test.types.p1.CrmostZla010Rosbtpartnera002)
                               Btpartneraddress (test.types.p1.CrmostZla010Rosbtpartnera001)
My Problem is now, that the XML-Structure got not that point "element1".
Instead of "element1" there is the point "item" in my XML-Structure in Word 2007.
I guess that is the Problem why i am not getting the fields of the Btpartneraddress filled in my Word.
Can anyone help me? Or put me in the right direction that i can change the XML?
Thanks for your help
André

Hi andré, I guess the issue is coming from the fact that you selected "AllPartiesInvolved" and that may contain any numbers of entries. So when you test your webservice, you put a key and then get a result for that key, and in that case you might get "element1" until "element3" for example if there was 3 partners involved in you activity.
But, when you design your template, you don't have a key at that moment, so in the Web Service structure, you have "items" which stands for all the possible entries you might retrieve at runtime. I guess you could use an index in your template to specify which item you need, but this is quite hasardeous, so i would be you, I would not design my web service to use "AllPartiesInvolved" but rather a specific Partner type like contact person for instance.

Problems with a new IP phone 7906 after factory reset

Hi Guys
I am currently having problems with my new IP phone 7906 after doing factory reset and here is a video of it:
http://www.youtube.com/watch?v=vvCLtwIAwVw
I used this command I found on the net:
Hold down
while plugging in the phone and keep holding it until the message waiting indicator (red light) starts blinking. Then
release # and type 123456789*0# in sequence.
I was trying to switch my phone to sip and it also dont want to take tftp setup either.

Tim,
Found this on the net
http://www.cisco.com/en/US/ts/fn/620/fn62949.html
Might be woth giving it a go
6.Pull power on the phone (even if power is PoE).
7.Hold down the # key on the phone.
8.Continue holding down the # key and re-apply power.
9.While still holding the # key wait for the Message Waiting Indicator (MWI) light on the handset to start flashing.
10.Once the MWI light is flashing, release the # key and enter the following sequence exactly on the keypad:
3491672850*#
Once this sequence has been entered on the IP Phone, if all the network criteria above have been met, it should begin its recovery process. This process can take up to 15 minutes to finish. The phone may appear to be doing nothing during this time. However, if the phone does not recover after 20 minutes then it is possible that the recovery is stuck. In this case, re-examine your network and verify that steps 1-4 are in place, then re-issue the factory reset sequence.
* Note: The factory reset sequence is a way for a phone to clear flash and still upload to a valid firmware image. This is facilitated by the termxx.default.loads file, but requires that the image files listed in the termxx.default.loads file are available in TFTP for the phone to download. Open the termxx.default.loads file in any text editor. This loads file is essentially just a packing list showing all the OS and application files the phone needs to function. The files include a cnu, cvm, dsp, app and jar files. Please make sure that these files as listed in the termxx.default.loads file are in TFTP. ("xx" will be either "06" for the CP-7906G model, or "11" for the CP-7911G model.)
Additional Diagnostic Steps:
- Try a hard-coded IP address as a test to see if this resolves the upgrade failures. If it does, and the number of failing IP Phones is relatively few, this procedure may be the most expedient. After the IP Phone upgrades successfully, reconfigure the IP Phone to use DHCP.
- Try putting the phone on a hub or a different switch and see if this helps change the startup timing enough so that the upgrade completes successfully.

Problem with castor xml mapping

Hi,
we have following problem with castor xml mapping.
How to use references in the collections(Hashmap or vector)?
WE have a method called getAttribute map which will return a hashmap consist different type of objects. We want to keep only the
references of objects if that object occurs more than once,instead of keeping the whole object
Following is the the xml mapping file.
<mapping>
<class name="com.opvista.ndtool.core.mos.ManagedObject" identity="Id" auto-complete="false" verify-constructable="false">
<map-to xml="ManagedObject"/>
<field name="Id" get-method="getId" set-method="setId" type="string">
<bind-xml name="Id" node="attribute"/>
</field>
<field name="AttributeMap" type="org.exolab.castor.mapping.MapItem" collection="map" get-method="getAttributeMap">
<bind-xml name="AttributeMap" node="element">
     <class name="org.exolab.castor.mapping.MapItem">
<field name="key" type="java.lang.Object">
     <bind-xml name="key" node="attribute"/>
</field>
<field name="value" type="java.lang.Object">
     <bind-xml name="value" node="element" reference="true"/>
     </field>
</class>
     </bind-xml>
</field>
</class>
</mapping>
we are using reference=true for the values. But it will throw below exception.
Unable to resolve ID for instance of class 'java.lang.String' due to the following error: Unable to resolve ClassDescriptor.

Please help us to overcome from this problem?
Thanks,
Dileep

for your ref here is what i think the basic mapping file would look like
<class name="Person">
<map-to xml="person"/>
<field name="name" type="string">
<bind-xml name="name" node="attribute" />
</field>
<field name="age" type="string">
<bind-xml name="age" node="attribute" />
</field>
</class>
<class name="MetaPerson">
<map-to xml="person"/>
<field name="dependents" type="string">
<bind-xml name="dependents" node="attribute" />
</field>
<field name="presentAdd" type="string">
<bind-xml name="present_add " node="attribute" />
</field>
<field name="permanentAdd" type="string">
<bind-xml name="permanent_add " node="attribute" />
</field>
</class>
however i am still not clear as to how i can use the metaperson object in the person class as well as in the mapping file.
hope this gives a better idea abt my problem statement.
Please help me out

I read files from the web, but there is a XML tag
with the encoding attribute in the RSS file.If you are quite sure that you have an encoding attribute set to ISO-8859-1 then I expect that your RSS file has non-ISO-8859-1 character though I thought all bytes -128 to 127 were valid ISO-8859-1 characters!
Many years ago I had a problem with an XML file with invalid characters. I wrote a simple filter (using FilterInputStream) that made sure that all the byes it processed were ASCII. My problem turned out to be characters with value zero which the Microsoft XML parser failed to process. It put the parser in an infinite loop!
In the filter, as each byte is read you could write out the Hex value. That way you should be able to find the offending character(s).

The problem with forecast reports in SCOM 2012 after integration with VMM 2012

Hello.
I have problem with forecast reports in SCOM 2012 after integration with VMM 2012. All other reports (not forecasting) works fine. For example, report “Host Group Forecasting” don’t work. The report is generated, but I have error: “Subreport
could not be shown”. I find only errors in SQL Server Reporting logs like this:
library!ReportServer_0-13!1758!06/26/2012-18:26:23:: i INFO: RenderForNewSession('/Microsoft.SystemCenter.VirtualMachineManager.2012.Reports/Microsoft.SystemCenter.VirtualMachineManager.2012.Report.ForecastHostGroup')

SQL collation for all SQL DB instances (SCOM and VMM and SCOM reporting) – “SQL_Latin1_General_CP1_CI_AS”
SQL Analysis service: SQL collation – “Latin1_General” ; language for the server – English (United States)
I think the problem in regional settings. By my opinion there are two possible mistakes:
SQL collation for all SQL DB instances. May be need use “Latin1_General_CI_AS”
as provided by
http://blogs.technet.com/b/momteam/archive/2012/05/25/clarification-on-sql-server-collation-requirements-for-system-center-2012.aspx
Need change regional setting. Question is for what (OS regional setting, SQL Analysis service settings,…) ?

Error: Subreport could not be shown
Opening a report for Client Security might result in the following error being displayed in one or more areas of the report: "Error: Subreport could not be shown."
Background
There are two possible reasons for this error:
1. Wrong location   The reporting server is pointing to the wrong computer running SQL Server or a SQL Server instance.
2. Insufficient permissions   The account configured (in SQL Server Reporting Services) to connect to the reporting database does not have appropriate permissions for the database.
Solution
To determine which reason is causing the error, attempt to directly open the subreport reporting the error, by clicking the name of the subreport.
If the reporting server is pointing to a wrong location, the report displays an error similar to the following:
Error message
An error has occurred during report processing.
Cannot create a connection to data source 'SystemCenterReporting'. Cannot open database "SystemCenterReporting" requested by the login. The login failed. Login failed for user username.
To verify the correct SQL Server computer and instance path
In Report Manager, navigate to the report generating the error and click the Properties tab.
Click Data Sources and under a Shared data source, note the path.
Open the reporting Web site. If you chose the default virtual directory for reports, the URL is: http://hostname/Reports/
If you chose to secure the viewing of reports with HTTPS, the URL is: https://hostname/Reports/
Click SCDW.
In the Connection type list, ensure that Microsoft SQL Server is selected.
In the Connection string box, ensure that the correct SQL Server computer and instance name are entered.
Note:
A period (.) denotes the local computer.
If the account has insufficient permissions, the report displays an error similar to the following:
Error message
An error has occurred during report processing. (rsProcessingAborted) Query execution failed for data set 'DSDashboardComputersTrend'. (rsErrorExecutingCommand) EXECUTE permission denied on object 'prSAS_UX_DashboardComputersTrend', database 'SystemCenterReporting',
schema 'dbo'.
To determine if you are experiencing the SQL Server permissions issue
Open the reporting Web site. If you chose the default virtual directory for reports, the URL is:http://hostname/Reportserver/
If you chose to secure the viewing of reports with HTTPS, the URL is:https://hostname/Reportserver/
Click Microsoft Operations Manager Reporting, click Microsoft Forefront Client Security, and scroll to DashboardComputersTrend.
Click DashboardComputersTrend.
If you are experiencing a SQL Server permissions issue, an error similar to the preceding error appears.
To grant permissions to the SQL Server computer
1. In Report Manager, click SCDW and note the account in the Connect using section. This is the account under which the database is contacted.
2. On the server with the System Center Reporting database, start SQL Server Management Studio.
3. In the tree, expand Security, and then expand Logins. Do one of the following:
If the user account is listed, right-click the account, click Properties, and then go to step 5.
If the user account is not listed, right-click Logins and choose New Login.
4. In the Login name box, enter the user account (domain\username).
5. In the Login Properties dialog box, click User Mapping, and then under Users mapped to this login, select the System Center Reporting check box.
6. Under Database role membership for: System Center Reporting, select the db_owner check box, and then click OK.

Problem with web.xml

Hello,
I have a big problem with web.xml.
i can run the servlet demos with the default web.xml, but when i try to user a costum web.xml files, i receive a 404 page not found on a link.
i have some dificulty to post here. but can somebody help my with my web.xml files?
thanks for your help.
have a nice day!

Be careful with the place of your files and folders. It's possible that you've just mentioned the cause of your problem.
My web.xml is
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>
<display-name>gco</display-name>
<description>gco webapplicaties</description>
<servlet>
<servlet-name>MopoController</servlet-name>
<servlet-class>org.gertcuppens.controller.MopoController</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>MopoController</servlet-name>
<url-pattern>/MOPO</url-pattern>
</servlet-mapping>
</web-app>
When I want to call my web application locally, I use the URL http://localhost:8080/gco/MOPO.
The http://localhost:8080 calls Tomcat. With /gco, Tomcat knows it should look for a folder gco inside the webapps folder. This one should contain a WEB-INF/web.xml folder for further instructions.
With /MOPO Tomcat knows, having read the web.xml files of all webapps folders at start, it should look for a servlet with the name MopoController. And this MopoController points to the class org.gertcuppens.controller.MopoController. So, Tomcat knows where to find everything.
Try to see whether your Tomcat can find everything inside the folders using your web.xml file.

Problem with"Evaluate User Policies"sch task after the upgrade OIM R1 to R2

Problem with "Evaluate User Policies" scheduled task after the upgrade from OIMg R1 to OIM 11g R2
After the upgrade process is completed we are having issue with Access policy not triggering if rule is set to custom attribute
- We had a Rule with custom attribute (Policy='Full-Time') the value gets populated by event handler which triggers the access policy in OIM 11g R1.. which worked fine in OIM R1
After the upgrade the value is getting populated but even after running "Evaluate User Policy" the Access Policy is not getting triggered.
We tested creating a rule with other custom attribute,policy does not trigger even after running Evaluate User Policy schedule Task in this case too
but if we try creating rule with OOTB attributes(Country='US') it works fine the access policy got triggered after running Evalute User Policy
One more issue we observed is
- Evaluate User Policy value usr_policy_update is not updated still set to '1' even after the Access policy got triggered (as it worked when rule is set to OOTB attribute)
I believe after the evaluate user policy gets triggered for a user it should update the value from '1' to '0')
Please let me know if you have any idea..Thanks!

well, I overcame the issue by 'fooling' the installer: on second node, change the scan ip address to point to something else (ie, different ip address to the scan in the first node, cleanup then rerun root.sh, it went past the trouble stage, then I still have problem later at the time database creation. I think scan ip address has to be setup correctly (round robin thingy)
This is how i did the cleanup before rerun root.sh

Problem with battery running down more quickly after I downloaded OS6 to 3GS iPhone.

gdgmacguy
I guess I should have asked for the "definitive" fix. I read several "fixes" but it seems no one knows if Apple has a definitive fix. Kind of like going into an Apple store and getting three different answers from three different reps. At least they are not rude and no, I don't have a problem searching the forum.

Noob Question: Problem with Persistence in First Entity Bean

Hey folks,
I have started with EJB3 just recently. After reading several books on the topic I finally started programming myself. I wanted to develop a little application for getting a feeling of the technology. So what I did is to create a AppClient, which calls a Stateless Session Bean. This Stateless Bean then adds an Entity to the Database. For doing this I use Netbeans 6.5 and the integrated glassfish. The problem I am facing is, that the mapping somehow doesnt work, but I have no clue why it doesn't work. I just get an EJBException.
I would be very thankfull if you guys could help me out of this. And don't forget this is my first ejb project - i might need a very detailed answer ... I know - noobs can be a real ....
So here is the code of the application. I have a few methods to do some extra work there, you can ignore them, there are of no use at the moment. All that is really implemented is testConnection() and testAddCompany(). The testconnection() Methode works pretty fine, but when it comes to the testAddCompany I get into problems.
Edit:As I found out just now, there is the possibility of Netbeans to add a Facade pattern to an Entity bean. If I use this, everythings fine and it works out to be perfect, however I am still curious, why the approach without the given classes by netbeans it doesn't work.
public class Main {
    private EntryRemote entryPoint = null;
    public static void main(String[] args) throws NamingException {
        Main main = new Main();
        main.runApplication();
    private void runApplication()throws NamingException{
        this.getContext();
        this.testConnection();
        this.testAddCompany();
        this.testAddShipmentAddress(1);
        this.testAddBillingAddress(1);
        this.testAddEmployee(1);
        this.addBankAccount(1);
    private void getContext() throws NamingException{
        InitialContext ctx = new InitialContext();
        this.entryPoint = (EntryRemote) ctx.lookup("Entry#ejb.EntryRemote");
    private void testConnection()
        System.err.println("Can Bean Entry be reached: " + entryPoint.isAlive());
    private void testAddCompany(){
        Company company = new Company();
        company.setName("JavaFreaks");
        entryPoint.addCompany(company);
        System.err.println("JavaFreaks has been placed in the db");
    }Here is the Stateless Session Bean. I added the PersistenceContext, and its also mapped in the persistence.xml file, however here the trouble starts.
import javax.ejb.Stateless;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
@Stateless(mappedName="Entry")
public class EntryBean implements EntryRemote {
    @PersistenceContext(unitName="PersistenceUnit") private EntityManager manager;
    public boolean isAlive() {
        return true;
    public boolean addCompany(Company company) {
        manager.persist(company);
        return true;
    public boolean addShipmentAddress(long companyId) {
        return false;
    public boolean addBillingAddress(long companyId) {
        return false;
    public boolean addEmployee(long companyId) {
        return false;
    public boolean addBankAccount(long companyId) {
        return false;
}That you guys and gals will have a complete overview of whats really going on, here is the Entity as well.
package ejb;
import java.io.Serializable;
import javax.persistence.*;

    private static final long serialVersionUID = 1L;

    private String name;
    public Long getId() {
        return id;
    public void setId(Long id) {
        this.id = id;
   public String getName() {
        return name;
    public void setName(String name) {
        this.name = name;
        System.err.println("SUCCESS: CompanyName SET");
    @Override
    public int hashCode() {
        int hash = 0;
        hash += (id != null ? id.hashCode() : 0);
        return hash;

        // TODO: Warning - this method won't work in the case the id fields are not set
        if (!(object instanceof Company)) {
            return false;
        Company other = (Company) object;
        if ((this.id == null && other.id != null) || (this.id != null && !this.id.equals(other.id))) {
            return false;

Well I don't understand this. If Netbeans created a Stateless Session Bean as a facade then it works -and it is implemented as a CMP, not as a BMP as you suggested.
I defenitely will try you suggestion, just for curiosity and to learn the technology, however I dont have see why BMP will work and CMP won't.
I also don't see why a stateless bean can not be a CMP. As far as I read it should not matter. Also on the link you sent me, I can't see anything related to that.
Maybe you can help me answering these questions.
I hope the above lines don't sound harsh. I really appreciate your input.
Best regards
Taggert
