I see that in the Spring configuration files , that scope="tenant" is used ?
I tried searching in Springsource.org , Spring forums and googled it but couldn't get much info.

a) where this will be used and in what contenxt?
b) what is the purpose of it?


thanks

Hi all,

I have an enterprise application which is developed using weblogic8.1
Currently I am upgrading the application to weblogic 10gR3.

I am not changing the java classes as per jdk 1.6.

As weblogic10.3 has backward compatibility I want the code to be up and running with minimal changes.

so When I build the code using ant I get the following error.

[java] [EJB:011017]Error while reading 'META-INF/weblogic-cmp-rdbms-jar.xml'. The error was: [java] [java] There are 1 nested errors: [java] weblogic.j2ee.validation.ComplianceException: The finder method findAll of ejb MyEJB cannot have both ejb-ql and wlql as null.

Hi all,

I am trying to delete a jar file in windows but Iget an error that "unable to delete the jar file".
I also checked my classpath and I dont have "." in my classpath .

I also closed all other applications but still the problem persists.

am I missing some thing here?

appreciate your inputs on this.

thanks,

Hi Deepak,

I am using the latest version only.

The Weblogic 10.3 comes with JAXB 2.1. The problem is the ObjectFactory.java created by the xjc task using JAXB 2.1 is different from the older ObjectFactory.java created using the JAXB1.3. The newInstance() method is missing in the newer version because of which the existing code that uses this method is facing problems.

I can see the problem with 2.1 version only as that newInstance() method is available even in JAXB 2.0.

The Final version of the JSR 222 ( Jaxb 2.1) Architecture Document says that the ObjectFactory has that method.

This can be shown in the following code snippet taken from the Architecture document.
public class ObjectFactory { // type factories Object newInstance(Class javaInterface){...} PurchaseOrderTypecreatePurchaseOrderType(){...} USAddresscreateUSAddress(){...} ItemscreateItems(){...} Items.ItemTypecreateItemsItemType(){...} // element factories JAXBElement<PurchaseOrderType>createPurchaseOrder(PurchaseOrderType){...} JAXBElement<String>createComment(String value){...} }
But I dont get that method when I try to generate the java files from the XSD document.

Can any one tell me what is the replacement for newInstance method in ObjectFactory (if there).

thanks,
Jyothsna

Hello Bala,

I am using now XJC compiler only from jdk1.6.

But in one of the java files my code is referring to the method newInstance(java.lang.Class) , which was
generated by jaxb1.0 in ObjectFactory class.
ie the method new Instance(java.lang.class) was available with jaxb1.0 version.

But with jaxb2.0 this method is no longer generated.

public Object findTemplate(Class klass ) throws Exception{ String className = klass.getName(); Object obj = objectFactory.newInstance(klass); }

Can any one tell me what should be the replacement for the above line of code.
I went through the specification but I didnt find any information so far.

am I missing anything here?

Hi all,

I have an xml and xsd files.

I am trying to generate java classes using xjc ant task in jdk 1.6.
xsd file :
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified"> <xs:element name="GuiField"> <xs:complexType> <xs:sequence> <xs:element ref="ValueMapper" minOccurs="0" maxOccurs="1"/> <xs:element ref="Query" maxOccurs="unbounded"/> </xs:sequence> <xs:attribute name="name" use="required"/> </xs:complexType> </xs:element> <xs:element name="ValueMapper"> <xs:complexType> <xs:sequence> <xs:element ref="Value" maxOccurs="unbounded"/> </xs:sequence> <xs:attribute name="defaultsamplValue" use="required"/> </xs:complexType> </xs:element> </xs:Schema>
xml file :

<GuiField name="mapd"> <ValueMapper defaultsamplValue="AUTO"> <Value guiValue="D" samplValue="MAP_D"/> </ValueMapper> </GuiField>
When I generated java classes using the initial version of ie 1.0 of Jaxb , I saw that GuiField and GuifieldType classes were generated.
but when I was migrating the application from weblogic 8.1 sp6 to weblogic 10.3 only one class was generated ie GuiField.
I am not knowing whats going wrong , as some classes were looking for GuiField type and it is not genereted.

In jdk 1.5 I used the following jars for jaxb ie jaxb-api.jar , jaxb-impl.jar , jaxp-api.jar , jaxb-lib.jar.

with JDK 1.6 I used that jars that come with bea weblogic.
ie glassfish.jaxb.xjc_2.1.6.jar ,glassfish.jaxb_2.1.6.jar


am I missing anything here?

thanks,

I am migrating the J2ee (1.4) application from 8.1sp6 to Oracle Weblogic server 10.3
I have set the environment in build.xml to point to Oracle weblogic server and the java to the one that comes with Oracleweblogic.

Rite now I am seeing the following error.

javac C:\Zdev10.3\sep09_Build\src\source\com\myapp\sample\ejb\external\pmt\ServicesBean.java:51: package org.apache.xerces.validators.datatype does not exist javac import org.apache.xerces.validators.datatype.XMLException; javac ^ javac C:\Zdev10.3\sep09_Build\src\source\com\myapp\sample\ejb\external\pmt\ServicesBean.java:109: cannot find symbol javac symbol : class XMLException javac location: class com.myapp.sample.ejb.external.pmt.ServicesBean javac public static String validateXML(String xmlRequest) throws XMLException { javac ^ javac C:\Zdev10.3\sep09_Build\src\source\com\myapp\sample\dao\tm\CommonTMDao.java:281: warning: non-varargs call of varargs method with inexact argument type for last parameter; javac cast to java.lang.Object for a varargs call http://javac] cast to java.lang.Object[ for a non-varargs call and to suppress this warning]

According to Oracle Weblogic , xerces is been not supported .

Also we need to go with the xerces.jar for some time.

Any ideas /inputs/work arounds on this will be appreciated.

Hi Amit,

I am also getting the same error when I am migrating my application from 8.1 SP6 to 9.2 MP3.

I get the same error when I am building the app through ant 1.7.

any inputs on this error?
