Info

In such a situation, we recommend that you e-mail the Oracle JHeadstart Team (idevcoe_nl@oracle.com), and send us the following information: • The JHeadstart version you are using. You can see this in JDeveloper by going to the Help menu -> JHeadstart Documentation Index. • The name of the form module that is causing the problem. • The error message and error stack trace displayed in the dialog window (if any) • Any log information written to the JDeveloper JFG log window • The XML files created during processing for this module: _extracted.xml, _migratedAdfbc.xml and migratedJhs.xml file. Depending on the phase in which the error occurred, not all of these files might be available for the form module. Please send us the files that are available. • Any other information that can help us understand your issue. For example, if you expected a different layout of the user interface, then attach screen shots of the original form, and the generated web page. • Note: if you send zipped attachments (preferred), then make sure you rename extension .zip to something else (.zipp), otherwise your e-mail will be bounced by the Oracle Mail Server. With this information, we might be able to reproduce the problem, and provide you with a patch that fixes the problem. 13.3.7. Processing the Same Form Multiple Times You can run the JFG multiple times for the same form. When you do this the following happens: • Existing entity objects will not be modified, only new attributes will be added if there are columns in the table that are not yet mapped to an attribute • Existing view objects will not be modified, only new attributes will be added if there are items in the block that are not yet mapped to an attribute • Existing application modules will not be modified, only new view object usages will be added if necessary • The groups generated for the form in the JHeadstart Application Definition will not be changed at all. If you want the JFG to recreate the group definitions, you first need to change the top-level group of the form and all its detail groups. JHeadstart Developer’s Guide Forms2ADF Generator 13 - 13
13.4. Understanding the Outputs of the JHeadstart Forms2ADF Generator 13.4.1. Generated ADF Business Components This section will give you a short overview of the output and explains how this can be related to Oracle Forms elements. It also discusses possible changes you might need to make to the generated outputs. 13.4.1.1. Entity Objects For each table or view used by an Oracle Forms data block, an Entity Object (EO) is created. These entity objects are shared across all forms modules: when multiple forms use the same table, only one entity object is created. The information to create an EO is queried from the data dictionary tables. This means that attributes are created for each column in the table, regardless of whether the column is actually used in a forms block. EO attributes are marked as key attributes based on the primary key definition in the data dictionary. If the table does not have a primary key, or the block is based on a view, then the JFG will default all mandatory attributes as primary key attributes. This is done because ADF Business Components requires each EO to have at least one key attribute. When this happens, a warning is written to the log window: When you an encounter such a warning, you should check which attributes really make up the primary key, and change the Primary Key checkbox in the EO attribute editor accordingly. 13.4.1.2. Entity Association Foreign Key constraints as found in the data dictionary are processed into Entity Associations. These Associations are created between the two EO’s created from the two tables between which the Foreign Key constraint lies. You can compare this to a client side implementation of a Foreign Key. 13.4.1.3. View Objects View Objects (VO) are created for each block in the form that is based on a table or view. These “block” VO’s are always based on the entity object that maps to the same table or view. For each data bound item within the block a VO attribute is created. In older forms, lookup data (like the department name in an employee block) is typically displayed in block items not based on a column. The values in these unbound items are typically set through a POST-QUERY trigger that performs lookup queries to associated tables. Since the JFG does not parse any PL/SQL logic, these lookup values will not be visible in the ADF web application that can be generated using the outputs of the JFG. 13 - 14 Forms2ADF Generator JHeadstart Developer’s Guide
