Eclipse Relational Mapping + wrong name exception

Dears,
I wanna ask three questions:
- I understand that TopLink will be replaced by EclipseLink. EclipseLink will have JPA + Relational Mapping? or the Relational Mapping is there only for backward compatiblity and all new products should use EclipseLink JPA?
- Is there any EclipseLink discussion forum?
- I am using EclipseLink + EJB 3.0, I am getting the following Exception:

The TopLink product continues to exist as Oracle commercial offering including EclipseLink. Those wanting professional support for their use of EclipseLink can get it through licensing of Oracle TopLink. In addition to the inclusion of EclipseLink our TopLink product also includes the original packaging of TopLink for backwards compatibility (including utilities) and TopLink Grid (Coherence integration).
Customers using TopLink's native relational mappings can upgrade to using EclipseLink's packages (using the package renamer) and continue to leverage the same functionality they are used to. As we add new features we endeavor to make them easily usable through the JPA interface but the native usage is always available.

ANN: Eclipse EJB 3.0 Object-Relational Mapping Project Requirements posted

A document that presents an intitial feature and use case list for the early milestones of the Eclipse EJB 3.0 Object/Relational Mapping project has been posted to the project newsgroup (news://news.eclipse.org/eclipse.technology.ejb-orm). It also demonstrates a set of user interface components for editing EJB 3.0 Entities. The document covers the basics and is designed to illustrate the concept. It is in no way comprehensive. For example, it doesn't thoroughly cover the editing of ORM xml descriptors although this is an important requirement for the project. ORM xml support will be detailed in coming revisions, and slated for future milestones.
The purpose of this document is to invite comment on the approach. If you are interested in EJB 3.0 Entity support in Eclipse please give the doc a look over and post your feedback to the EJB 3.0 Object-Relational Mapping Project newsgroup.

Project Overview:
The goal of this project is to add comprehensive support to the Eclipse Project for the definition and editing of Object-Relational (O/R) mappings for EJB 3.0 Entity Beans. EJB 3.0 O/R mapping support will focus on minimizing the complexity of mapping by providing creation and automated initial mapping wizards, and programming assistance such as dynamic problem identification. The implementation will be extensible so third party vendors can add to its functionality.

Wrong name error if I mess up url string case

Hi:
          I have a url as the following: http://localhost:7001/APP/a.jsp. If I
          close browser and type it as lower case url
          http://localhost:7001/app/a.jsp later time, it will cause a null pointer
          exception(wrong name error). Is the url case sensitivity problem been
          fixed by any service pack.
          Thanks,
          David


Okay, I made a simpler web application. I have:
index.html
WEB-INF/
my WEF-INF directory looks like:
classes/
lib/
web.xml
my only servlet is WEB-INF/classes/com/servTest.class
I defined the servlet in my web.xml like this:

<servlet>
<servlet-name>servTest</servlet-name>
<servlet-class>com.servTest</servlet-class>
</servlet>

<servlet-mapping>
<servlet-name>servTest</servlet-name>
<url-pattern>/servTest</url-pattern>
</servlet-mapping>
However, I still get the same error (NoClassDefFoundError .... wrong name: servTest blah blah)
I am trying to access the servlet by the url http://localhost:8080/servTest/servTest and I've also tried http://localhost:8080/servTest/com.servTest. I also tried linking to it in my index via a form with action="servTest". I've also tried action="com.servTest" however I still can't seem to get past this wrong name error. However, I can create servlets fine without trying to use packages (i.e. if i place .class files directly in WEB-INF/classes), but I would really like to have packages working. Can anyone see any potential errors? thanks!

Jabber Client CallerId displays wrong name

Hi,
I have a problem with the wrong name displaying in Jabber calls. This only occurs when John calls from his Jabber Client. There is always the CallerId of Sam showing up.
Checked AD, Outlook contacts, CUCM & Webex configuration and found no errors.
Then I generated a problem record in my Jabber for Windows client and found this in PROBLEM_FEEDBACK_Cisco_Jabber_17.49_01-08-2013\Contacts\PersonManager\PersonManagerForensics.txt:
[1] <PersonResolver: 0D32AD90>
Original record: <0D36E2B8>
<Person: 0D36E370>
<PersonRecord: 0D36E2B8> (Roster:[email protected])
<PersonRecord: 09349160> Sam Sample (WebEx:[email protected])
<PersonRecord: 0F10FE60> Doe, John (CallerID:+491234567890:Doe, John)
In the other records there is only one name associated to one person. How did John number slip in here. And most interesting, how can I get rid of that entry? Where is it originated?
Same Problem occurs at a customer site with a on premise deployment (CUPS). So it doesn't seem to be Webex related. Tried several Jabber versions from 9.1.3 to 9.2.3. Same behaviour.
Any suggestions hints?
Regards
Andre

I think I see what is going on, just not entirely sure why and how to prevent it yet.
Look at the two records below, taken from the "PersonManagerForensics.txt" file generated once you report a problem through the Jabber application.
That first contact is a personal contact in the users Outlook address book.
The second contact is an employee.
When the user calls the second contact in Jabber, the caller ID always shows up as first contact. Same thing happens if the second contact calls the user.
The caller ID for the first contact is the same last 4 digits as the internal employees DID number. We use 4 digit dialing. Not really sure why the caller ID record for the first contact resolved to those last 4 digits of that one telephone number.
Jabber issue....or Outlook issue???
I'll open a TAC case.

Wrong Name Error

Hi,
I created a package in eclipse with 3 .java files under it.
In each of the three java files I have included the "package testpackage;" clause at the top.
My first 2 files (lets call them one.java and two.java) is referenced in three.java, thus I use the import statement for both one and two in three.java.
After I compile all 3 successfully in Eclipse, I go to the command line, to the specific directory (testpackage) and run: java one, but I get the message:
NoClassDefFoundError: 1 (wrong name: testpackage/one)
What is wrong?

I found that you need to be in the PACKAGE directory when you execute the "java" command, not the directory containing the .class file(s). For example, if you have the following statement in your java program:
package buServer;
Your .class files (BUreceiver.class in my case) will reside in a directory named buServer. You need to be in the directory ABOVE the one that contains your class files (the package directory) and execute the program as shown below:
java buServer/BUreceiver
The above assumes that the current directory is in your CLASSPATH or is given by the " -cp ." on the java command line.
The basic problem, I think, is that CLASSPATH points to directories that are supposed to contain .class files. When you use a package, you have to give the fully quallified name of the class with a root beginning in one of the directories in the CLASSPATH. In my case, the "package" statement says my class should be in a <CLASSPATH>\buServer\ directory. When I was in the buServer directory (containing my .class files) and added it to the CLASSPATH, there was no <CLASSPATH>\buServer\ directory, since the buServer\ directory was inside CLASSPATH. However, when I tried to execute it without qualifying it with the "buServer", it saw the package statement in the class file that was there and gave me the "wrong name" error.
Another solution would have been to take out the package statement from the program.

Wrong name in email address and damaged index in address book

I have experienced this problem for months now. I have a Mac Pro at the office and MacBook Pro at home. The address book is synced with .mac. At random I will receive emails and the mail program will attach the wrong name with the address ( John doe [email protected] will be displayed as mary smith [email protected] ) this also happens in mail I have sent and copied myself on. The incorrect name is usually one that exist in my address book. The second part of the problem which may be related is the index for both address books will get damaged. Every few days I have to discard the address book index file ( AddressBook-v22.abcddb ) which fixes the index issue for a few days. The computers nor the applications ever crash. I wonder if the .mac syncing could be key to both computers having index issues. Rebuilding the address index does not fix the wrong name issue. Both computers are 10.5.2. I feel there is some deeper corruption issue that rebuilding that one index file does not correct. I have also rebuilt all the mail boxes.

SOLUTION: my ultimate solution to the address book confusing contact info in ichat, mail, etc. was to go to ~/Library/Application Support/AddressBook/ and delete the AddressBook-v22.abcddb file. back up your contacts first!!! but after you delete and relaunch, Address Book will rebuild using the info from the Metadata folder. worked like a charm.

Need help in Object-Relational Mapping

I'm writing a simple two-tiered business application with Swing application on the client side and a DBMS on the server side. To make my client code more maintainable, I decided to create Business Objects instead of having my client accessing the database directly via SQL. For simplicity, I'm not using any features from the J2EE framework, and the Business Objects will be hosted on the client side, with one-to-one mapping to tables in the database. Since this is my first attempt in Object-Relational Mapping, I'm faced with the following problems:
1. What kind of methods are appropriate for business objects? For example, if I have a Machine and Employee entity. A Machine is owned by an employee, and this is represented in the DB by storing the employee ID (not the name) as a foreign key in the Machine table. Let's say in the user interface I have a table that needs to display the list of Machines, but instead of displaying the owner employee's ID, I want to display the owner employee's name by doing a join select. Should the findMachines() method always perform a join select to get owner's name and store it in the Machine object which is returned, or should findMachines() simply return the owner's ID so the UI will need to make another SQL call (through the Employee object) to get the employee's name? The latter is more elegant, but would it be horribly inefficient if there are lots of machines to be displayed (and for each machine we make a separate select call to get the owner's name).

Business objects should be separate from how they're persisted.
When you say object-relational mapping, do you mean a tool like Hibernate? Or are you writing your own persistence layer using JDBC and SQL?
I'd recommend that you read about the Data Access Object pattern and keep the persistence code out of the business objects themselves:

Invalid column name exception

I am receiving an Invalid column name SQLException. I initially
thought it was a problem with the computed fields, but was after
making the usual changes to the model implementation the exception is
still occurring. I can run the SQL statement in SQLplus and get no
errors and the three results I'm expecting (grabbing the SQL statement
from the model's beforeExecute event). The mystifying part is that it
returns one of the three rows that I'm expecting. That is, the model
executes and the result set is partially filled. The model is Select
only. The computed fields are concatenated strings. After logging the
exception I call getNumRows() on the model and receive a 1 back. The
computed fields are returned in that one record. Any ideas about what
to try or where to look next?
Thanks,
paul

Kostas,
Thanks for your help. During migration a QueryFieldDescriptor was
created for a field that is only used in the where clause. I'm
assuming it then couldn't be mapped back to the ResultSet, and this
caused the Invalid Column Name exception. That is, I am selecting 5
fields, but had 6 QueryFieldDescriptors.

Hi Paul,
It would appear you have a column name mismatch between what isdefines in
your modelImpl
and what is being returned by the JDBC driver.
From the SQL you sent, the Column Names would be something like:
'SURVEYGROUP_XREF',SURVEY_ID', CF_SURVEYANDGROUP', 'CF_SURVEYGROUP',
'RESULTS_VIEWER_ID'
Do all your column names definitions in your modelImpl match up tothese ?

eg public static final StringCOLUMN_WIS_SURVEYANDGROUP="CF_SURVEYANDGROUP";

Note: the qualified column vairables (QUALIFIED_COLUMN_XXXXXX) doNOT get
used for Select queries.
If it still unclear where the mismatch is occurring, you can addsome simple
debugging :
To tell you what you are trying to access add the the following in
ResultSetModelBase just before the
exception occurred:
System.out.println("UPDATE_MODEL: Attempting to Access Column Name:
"+fd.getColumnName());
Object value=resultSet.getObject(fd.getColumnName());
If still need more information,you can look at the column namesreturned by
the JDBC calls by doing something like:
ResultSetMetaData metaData = resultSet.getMetaData();
int columnCount = metaData.getColumnCount();
for(int i = 0; i < columnCount ; i++)
System.out.println("Colummn["+i+"]"+
metaData.getColumnName(i+1));
Hope that helps.

Annoying-as-hell 'wrong name' error

Hi all,
Okay, so I've got a Java app that compiles fine (ProxyTool.class), and works fine in Eclipse... but when I try to call it from the command-line (java ProxyTool), I'm getting this un-useful and un-helpful error: java.lang.NoClassDefFoundError: ProxyTool (wrong name: test/sys/ProxyTool).
I then attempt to do java /test/sys/ProxyTool, and I get java.lang.NoClassDefFoundError test/sys/ProxyTool.
Can someone please just tell me what I need to run this g*ddamn app? This is driving me nuts.

I had run the previous command from the package root - I simply thought I had to give a full path to the .class files. Simply using "bin" instead of the full path worked.Of course it worked, that's what I told you to do in the first place.
I completely understand (I think) the concept of a package as a logical container. I am completely baffled as to why it is this finicky in Java. I'm assuming the .NET equivalent is a namespace, and it's not nearly this termpermental!It is not finicky, you were just doing random stuff instead of reading the documentation on how packages work.

Getting Bad Applet class name exception while opening applet.

While opening an applet in my mac os x v10.6.8 machine i am getting "Bad Applet class name exception" which is working fine in mac os x v10.7.5.Java version in my mac is 1.6.0_43.Can anyone please help me to resolve this.

Apple barred Java from running on Macs in order to safeguard users by blocking Java 7 Update 11 and adding it to the banned list in XProtect.
This was the second time in two weeks that Apple had blocked Oracle's code from running on Macs. The threat was so serious that the U.S. Department of Homeland Security had recommended that all Java 7 users disable or uninstall the software until a patch was issued. This time Java is blocked through Apple's XProtect anti-malware feature.
Java has come under fire as the means by which hackers have been able to gain control of computers. In April 2012 more than 600,000 Macs were reported to have been infected with a Flashback Trojan horse that was being installed on people's computers with the help of Java exploits. Then in August Macs were again at risk due to a flaw in Java, this time around, there was good news for Mac users: Thanks to changes Apple has made, most of us were safe from the threat.
Unwilling to leave its customers open to potential threats Apple decided it's safer to block Java entirely.
In order to block older versions of Flash, Apple has updated its "Xprotect.plist" file so that any versions that come before the current one (version 11.6.602.171) cannot be used on a Mac. Users who have older versions of Flash installed will be greeted with an alert that says "Blocked plug-in," and Safari will prompt the user to update to a newer version.
Macs running OS X Snow Leopard and beyond are affected.
UPDATE for those running Lion or Mountain Lion:
Oracle on Friday February 1 released a new version reportedly addressing vulnerabilities seen with the last build.
Apple disabled Java 7 through the OS X XProtect anti-malware system, requiring users to have at least version "1.7.0_10-b19" installed on their Macs. The release dated February 1 carries the designation "1.7.0_13-b20," meeting Apple's requirements.
Oracle "strongly recommends" applying the CPU fixes as soon as possible, saying that the latest Critical Patch Update contains 50 new security fixes across all Jave SE products.
Update for Snow Leopard users:
Apple issued update 12 for Java for OS 10.6:
http://support.apple.com/kb/DL1573
Note: On systems that have not already installed Java for Mac OS X 10.6 update 9 or later, this update will configure web browsers to not automatically run Java applets. Java applets may be re-enabled by clicking the region labeled "Inactive plug-in" on a web page. If no applets have been run for an extended period of time, the Java web plug-in will deactivate.
If, after installing Java for OS X 2013-002 and the latest version of Java 7 from Oracle, you want to disable Java 7 and re-enable the Apple-provided Java SE 6 web plug-in and Web Start functionality, follow these steps:
http://support.apple.com/kb/HT5559?viewlocale=en_US
Further update:
Apple issued this Java related security update No. 13 on February 19:
http://support.apple.com/kb/HT5666
and Update No. 14 on March 4: http://support.apple.com/kb/DL1573
http://support.apple.com/kb/HT5677
You should also read this:
https://support.apple.com/kb/HT5672
The standard recommendation is for users to turn off Java except when they have to use it on known and trusted websites (like their bank). Javascript, which is unrelated despite the name, can be left on.

Bonjour chat coming from wrong name but right person

I have multiple users in an organization that use Bonjour to chat with each other. Ever since the update to Yosemite we've been noticing that they aren't able to chat each other directly but in the reverse it works but from the wrong name.
Example:
Mike cannot chat James
Matthew cannot chat Mike
When James chats Mike it comes through as Matthew
This only happens for select users and seems to have no pattern to it. It has even happened mid-chat where the recipient was showing one person then several chat messages later they started coming from someone completely different. We've verified the names are correct in the Contacts app under the "My Card", the computer names are all different, and all are using a verified time server (otherwise multiple other applications would not be working).
I've tried removing ~/Library/Preferences/By Host as well as ~/Library/Preferences/com.apple.ichat* and com.apple.im* and com.apple.messages*

Hi,
There are two possible causes, one of which you mention about the My Card details.
The other is the Computer name in System Preferences > Sharing.
Bonjour Computers automatically show in Shares in the Finder's Side Bar (If you have that preferences set).
They show as the name from the Sharing Pane.
Workplace and campus type settings that update via a central DiskImage can have issues if the computer's names all become the same.
You don't need to remove all those .plists
Concentrate on the com.apple.iChat.Subnet.plist as this keeps the Bonjour info.
Possibly com.apple.imagent.plist as this does the "listening" for incoming invites for all account in Messages and FaceTime.
I would also look at the Contacts App's Preferences and check how many Accounts are active.
I have had issue where iCloud and Yahoo have both been active. Once I had an issue with On My Mac being active at the same time as iCloud which I have not be able to replicate since I sorted it.
I was Screen Sharing in Messages to Snow Leopard (iChat 5) yesterday concerning another issue about naming.
I used an AIM account not linked to an Address Card on the iMac (Yosemite) to a account on the MacBook Pro/Snow Leopard that is not known to the iMac (it does not appear on any Address Card relating to the MacBook Pro or other contact)
The MacBook Pro/ iChat 5 showed the Buddy as my full name despite it not appearing in any Address card on that computer. (my Names does but not the Apple ID as Valid AIM Screen Name I was using)
Strangely I was using my Main AIM name at one point on the MacBook Pro but the iMac knows that as it is in the Address Card and said I was screen Sharing with the iMac.
Whilst not Bonjour it does show that something has changed about the way Messages in Yosemite looks at the info about who is calling or in some form of connection with you.
At the same time I did notice the Bonjour Buddy Lists displayed the correct info for the "Buddy' on the other computer (Address Book/Contacts app My Card info).
I would check the general Bonjour Sharing first.

Java.lang.NoClassDefFoundError: src/myproject/myapp (wrong name: myproject/

Hi
I was trying to build an app using JBuilder personal. It would build and run fine. Then i realised that i could not use the api from jdk1.4 as JBuilder would only work with jdk1.3.
So, i moved the project from JBuilder to Forte thinking that Forte would allow me to use the jdk1.4 api. After significant trouble porting the project, i got the project to build successfully.
But when i try to run it , i get the following error
What could be causing it and how do i fix it? these errors are very frustrating. searching this site or the forte help, hasnt given me any tips yet. Thanks

Exception in thread "main"

But when i try to run from Forte, it still gives the same dumb errors ..
Could it be a Forte settings problem??Definitely. Choose the Project menu, then the Settings... at the bottom. That brings you up a new dialog. On the left, select the "Execution types", and the "external execution" within. On the right pane, click on the "expert" tab on the bottom. There you have a field named classpath; add your classpath directories there. Then your program will probably run from Forte.
For compiling, you also should set the classpath; you need "Compiler types" on the left pane, and you have to set the classpath for the fastJavac compilation and/or for the external compilation, depending which one you use.
On the left also a "Java Sources" node - click on it, and check if the "default compilation" is either external or (preferable) fastJavac; and that the default execution is external.
How Forte works with internal compilation, and internal execution, I don't know, never tried that.
Best Regards,
Ivan

Syntax of DDL options and related (table) column names

Hi,
where can I find something like a mapping between DDL options and related table column names?
For example I do have the table options PCTFREE, FREELISTS and NOCOMPRESS. The related table columns out of user_tables are PCT_FREE, FREELIST and COMPRESS.
PCT(_)FREE wins an Underscore, FREELIST(S) wins an "S" and it is "NOCOMPRESS" if COMPRESS has a value "Y(es)".
Hope somebody can help.

So far I didn't find any information that is not in
the DDL script gernerated from
DBMS_METADATA.get_DDL.Alright, I give you an example:
I create a table with the following DDL:
"CREATE TABLE IntBuch (
int_bunr integer NOT NULL,
int_sdat double precision NOT NULL,
int_hblz char(8) NOT NULL,
int_hkto char(7) NOT NULL,
int_hdat double precision NOT NULL,
KtoNr char(7) NOT NULL,
BLZ char(8) NOT NULL,
CONSTRAINT PK_IntBuch PRIMARY KEY (int_bunr)
USING INDEX
PCTFREE 10
STORAGE (
INITIAL 1000
NEXT 500
PCTINCREASE 0
MINEXTENTS 1
MAXEXTENTS 4096
PCTFREE 20
LOGGING
CREATE UNIQUE INDEX intid
ON IntBuch (int_bunr DESC)
CREATE INDEX hkto
ON IntBuch (int_hblz,int_hkto)
COMMENT ON TABLE IntBuch
IS 'Kommentar zu DB-Tabelle InBuch'
COMMENT ON COLUMN IntBuch.int_sdat IS 'Kommentar zu DB-Spalte int_sdat'
ALTER TABLE IntBuch
ADD CONSTRAINT Gutschrift FOREIGN KEY (int_hkto,int_hblz) REFERENCES Konto
ON DELETE CASCADE
ADD FOREIGN KEY (KtoNr,BLZ) REFERENCES Konto
ADD FOREIGN KEY (int_bunr) REFERENCES Buchung
ON DELETE CASCADE
After that I read the DDL with DBMS_METADATA.get_DDL and I get
" CREATE TABLE "UOENDE"."INTBUCH"
(     "INT_BUNR" NUMBER(*,0) NOT NULL ENABLE,
     "INT_SDAT" FLOAT(126) NOT NULL ENABLE,

     "INT_HKTO" CHAR(7) NOT NULL ENABLE,
     "INT_HDAT" FLOAT(126) NOT NULL ENABLE,
     "KTONR" CHAR(7) NOT NULL ENABLE,
     "BLZ" CHAR(8) NOT NULL ENABLE,
     CONSTRAINT "PK_INTBUCH" PRIMARY KEY ("INT_BUNR")
USING INDEX PCTFREE 10 INITRANS 2 MAXTRANS 255 COMPUTE STATISTICS

     CONSTRAINT "GUTSCHRIFT" FOREIGN KEY ("INT_HKTO", "INT_HBLZ")
     REFERENCES "UOENDE"."KONTO" ("KTONR", "BLZ") ON DELETE CASCADE ENABLE,
     FOREIGN KEY ("KTONR", "BLZ")
     REFERENCES "UOENDE"."KONTO" ("KTONR", "BLZ") ENABLE,
     FOREIGN KEY ("INT_BUNR")
     REFERENCES "UOENDE"."BUCHUNG" ("BU_NR") ON DELETE CASCADE ENABLE

PCTINCREASE 0 FREELISTS 1 FREELIST GROUPS 1 BUFFER_POOL DEFAULT)
TABLESPACE "USERS"
If there are no more DDLOptions possible than that, it is fine for me. If not, but all kinds of options are to find in only one or two tables of the database ( user_tables for table options, dba_constraints and dba_segments for column options, primary and foreign keys, user_indexes and user_segments for indexes ...), that is fine for me, too. (As long as I get to know which tables are "sufficient" for that.) If it is different than both of that, that's bad.
However if you want to use defaults instead of
absolut values, it is better to remove certain parts,
like the storage clause, from the generated output.I understand this, but I am more interested to have all and not leaving out some of them in order to have the defaults in the database after running the DDL.
A totally different approach could be to
a) create a database link from one DB to another.
b) create table <new_table> as select * from
<old_table@dbLink> where 1=2;I keep that in mind, thanks for that hint.
