EclipseLink checks each project, descriptor, and mapping to ensure that you have properly defined the required settings. Errors and warnings are displayed in the Problems window of the EclipseLink Workbench.

You can also create a project status report that contains all errors in a specific project.

This section also includes information on the following:


Miscellaneous Errors (1 – 89, 106 – 133)

This section lists EclipseLink Workbench error codes, information about the likely cause of the problem, and a possible corrective action.


13
No class indicator field should be defined for the abstract class [class].
Cause: Abstract classes should not be included or contain an Indicator Value on a descriptor's Inheritance tab.
Action: You must either remove the Include option for the class on the Inheritance tab, or remove the abstract modifier option on the descriptor's Class Info – Class tab. See Descriptors and Inheritance and Configuring a Descriptor.


54
No class indicator field is selected for this root class.
Cause: You selected the Use Class Indicator Field option for the root descriptor in the inheritance hierarchy, but did not specify an indicator field for the root and its children.
Action: Use the Field Selection list on the Inheritance tab for the root class. See Descriptors and Inheritance and Configuring a Descriptor.


55
No class indicator value is defined for this included descriptor [class]
Cause: You selected the Use Class Indicator Dictionary option for the root descriptor in the inheritance hierarchy, but did not specify an indicator value for the root and its children.
Action: Use the Indicator Type list on the Inheritance tab for the root class. See Descriptors and Inheritance and Configuring a Descriptor.


89
Root class does not include an indicator mapping for this descriptor.
Cause: The root class in the inheritance hierarchy is set to the Use Class Indicator Dictionary option. The dictionary does not contain an indicator value for this child class.
Action: Select an Indicator Type on the Inheritance tab of the root class that includes the child types. See Descriptors and Inheritance and Configuring a Descriptor.


106
Mulitple mapping [mappings] write to the database field [db field] .
Cause: One database field is populated by more than one mapping
Action: Ensure the "one mapping per field" ratio for write operations.


118
The selected parent descriptor for this descriptor's inheritance policy does not have an associated inheritance policy.
Cause: Missing descriptor's inheritance policy.
Action: Ensure that the descriptor you are using has a valid associated inheritance policy (InheritancePolicy). See Descriptors and Inheritance and Configuring Inheritance for a Parent (Root) Descriptor.


123
This root class has no class indicator mappings for its hierarchy.
Cause: You created an inheritance policy with the Use Class Indicator Dictionary option but did not specify the indicator values for all subclasses.
Action: Specify the indicator values for all subclasses on the descriptor's Inheritance tab. See Descriptors and Inheritance and Configuring Inheritance for a Child (Branch or Leaf) Class Descriptor.

Note: EclipseLink displays a list of each subclass and indicator value if you have identified the subclasses' parent descriptor.



126
Writable mappings defined for the class indicator field [field name].
Cause: You selected the Use Class Indicator Field option for the root descriptor in the inheritance hierarchy, but the mappings for this field are writable.
Action: Select a Use Class Indicator Field on the descriptor's Inheritance tab that does not contain any writable mappings. See the following:


132
The implemented interface [interface] is not an interface.
Cause: You selected a noninterface (a class) as an implemented interface.
Action: Ensure that you select an interface. See Descriptors and Inheritance and Configuring a Descriptor.


133
The superclass for [class] is an interface, classes cannot extend interfaces.
Cause: You selected an interface instead of a class as a parent for your child class.
Action: Use the Inheritance tab for the root class. See Descriptors and Inheritance and Configuring a Descriptor.



Project Errors (100 – 102)

This section lists EclipseLink Workbench project errors.


100
The project caches all statments by default for queries, but does not bind all parameters.
Cause: A named query that caches statements must also bind parameters.
Action: On the Named Queries – Options tab, change the Cache Statement field to False, or change the Bind Parameters field to True. See Configuring Named Query Options.


101
The project uses a custom sequence table, but the counter field is not specified.
Cause: On the project's Sequencing tab, you selected Use Custom Sequence Table, but did not complete the Counter Field field.
Action: Select the field to use as the Counter Field for this sequence table. See Configuring Sequencing at the Project Level for details.


102
The project uses a custom sequence table, but the name field is not specified.
Cause: On the project's Sequencing tab, you selected Use Custom Sequence Table, but did not complete the Name Field field.

220
An aggregate shared by multiple source descriptors cannot have one-to-many or many-to-many mappings.
Cause: You attempted to create multiple one-to-many and many-to-many, or one-to-one mappings in which the target is the aggregate. Aggregate descriptors that are shared by multiple source descriptors cannot have mappings that contain a target object that references the descriptor.
Action: For aggregate descriptors that are shared by multiple source descriptors, remove mappings that contain a target object that references the descriptor. See Descriptors and Creating Relational Aggregate Descriptors.


221
Classes cannot reference an aggregate target with one-to-one, one-to-many, or many-to-many mappings.
Cause: You tried to select an aggregate descriptor as a reference.

Action: Ensure that the parent and child class have the same number of primary keys on the descriptor's Descriptor Info tab. See Configuring Associated Tables.


234
The primary keys do not match parent's primary keys.
Cause: In an inheritance hierarchy, the child's primary key(s) does not match the root's primary key(s).
Action: Ensure that each child's Primary Key on the Descriptor Info tab matches the parent's primary key. Ensure that the parent and child class have the same primary keys on the descriptor's Descriptor Info tab. See Configuring Associated Tables.


235

330
The returning policy insert fields do not exist on this descriptor's associated tables: [field name]
Cause: The field you selected on the descriptor's Returning tab does not exist on the database table associated with the descriptor.
Action: Select a different database table in the Insert area of the descriptor's Returning tab.


331
The returning policy update field [field name] does not exist on this descriptor's associated tables.
Cause: The field you selected on the descriptor's Returning tab does not exist on the database table associated with the descriptor.
Action: Select a different database table in the Update area of the descriptor's Returning tab.


350
Descriptors with Unknown Primary Keys must use sequencing.
Cause: Unknown Primary Key Class is selected for this descriptor, but the descriptor does not use sequencing.

Mapping Errors (400 – 483)

This section lists EclipseLink Workbench mapping errors.


400
Method accessors have not been selected.
Cause: You selected Use Method Accessing for a mapping, but you did not select a method.
Action: You must select a Get and Set method on the mapping's General tab. See Configuring Method or Direct Field Accessing at the Mapping Level.


401, 402
The [get/set access method] method for this mapping's method accessing field is no longer visible to this descriptor.
Cause: You changed the class hierarchy within the project, causing the method access type (get or set) to no longer be visible to the class.
Action: Ensure that the selected method is visible to the class.


403
Mappings for EJB 2.0 CMP descriptors that use Value Holder Indirection must not use method accessing.
Cause: You cannot use method accessing on mappings for EJB 2.0 CMP descriptors that use ValueHolder Indirection.
Action: Because EJB attributes are code-generated, reference mappings should not be set to use method access. The attributes are code-generated to be of type ValueHolder but the abstract methods are defined to return the local interface type of the related bean.


404
Mapping references a write-lock field, but it is not read-only.
Cause: You specified a locking policy for a descriptor, but one of the attribute mappings is not read-only.
Action: Select the Read Only option on the mapping's General tab.


410

Common Classpath Problems

The following are some common EclipseLink Workbench error messages that may result from invalid classpath information. See Configuring Project Classpath for more information.


The EclipseLink Workbench does not display the class(es) to import.
Cause: Your classes are not available for import on the Select Classes dialog box.
Action: Ensure that the class is in your project's classpath (on the project's General properties tab). Ensure that the class is in the .zip or .jar file. You cannot import compressed classes.


The EclipseLink Workbench generates an exception error when importing classes.
Cause: EclipseLink class import utility did not start correctly. One of the classes includes a static initialization method, which may cause the import utility to fail.
Action: Ensure that your project's classpath points to the root directory of your package hierarchy. For example, to import the com.company.class package in the C:\classes\com\company directory, your project classpath should be C:\classes\.


The EclipseLink Workbench fails to import the class, but does not generate an exception error.
Cause: The classpath containing your JDBC drivers should still be on your system CLASSPATH. EclipseLink Workbench classpath is for domain classes only.
Action: Ensure that you have properly indicated the directories that contain your domain class(es) to map on the project's General tab.


Database Connection Problems

This section describes common errors and problems you may encounter when communicating with or logging in to the database.


The class [class] was not found.
Cause: You attempted to log in to the database, but EclipseLink could not find the JDBC driver for the database.
Action: Ensure that the JDBC_CLASSPATH in the setenv.cmd file points to your JDBC driver JAR files. Verify that your PATH includes all files (for example, native .dll files) required by the driver. If the path to your JDBC driver JAR files contains spaces, then the path must be enclosed in double-quotes in the setenv.cmd file. For example:
set JDBC_CLASSPATH="C:\Program Files\some directory\driver.jar\"

For more information, see Configuring the EclipseLink Workbench Environment.


Username or password could be invalid.
Cause: EclipseLink was unable to log in to the database.
Action: Ensure that the Username and Password for the database are correct.Verify with your DBA that the database is set up and operating correctly.


You must define a development login.
Cause: You attempted to log in to the database from EclipseLink Workbench, but you did not define a development login.
Action: On the database property sheet, select a Development Login, or create a new Defined Login. See Configuring Login Information at the Project Level.


No database driver has been specified.
Cause: You attempted to log in to the database from EclipseLink Workbench, but you did not complete the login information.
