Eclipse GlassFish Upgrade Compatibility Issues

2 Eclipse GlassFish Upgrade Compatibility Issues

This section describes some compatibility issues between Eclipse GlassFish 7 and earlier product releases. This section also describes some compatibility issues that affect Java applications that run on earlier product releases with which Eclipse GlassFish 7 is binary-compatible. When you upgrade to Eclipse GlassFish 7, you must address these issues.

The following topics are addressed here:

Binary-Compatible Releases For Eclipse GlassFish 7

Eclipse GlassFish 7 is NOT binary-compatible with the earlier releases of the software:

  • Sun GlassFish Enterprise Server v2.1.1 (Enterprise and Developer Profiles)

  • Sun GlassFish Enterprise Server v3

  • GlassFish Server Open Source Edition 3.0.1

  • GlassFish Server Open Source Edition 3.1

  • GlassFish Server Open Source Edition 3.1.1

  • GlassFish Server Open Source Edition 4.x

  • GlassFish Server Open Source Edition 5.x

  • Eclipse GlassFish 6.x

Java applications that run on these releases also work on Eclipse GlassFish 7 except for the compatibility issues that are listed in the remainder of this chapter.

The compatibility issues that are listed in the remainder of this chapter do not affect Java applications that run on Sun GlassFish Enterprise Server v3 and Eclipse GlassFish 3.0.1. The differences between Eclipse GlassFish 7 and the Enterprise Server v3 releases do not affect applications and data.

New Default Installation Directory

The default Eclipse GlassFish 7 installation directories are as follows:

Solaris, Linux, and Mac OS X systems
user-home-directory/glassfish7
Windows systems
SystemDrive\glassfish7

Changes to Group Management Service Settings

The functionality of the Group Management Service (GMS) has not changed since Sun GlassFish Enterprise Server v2.1.1, but the names of GMS settings have been changed in the Administration Console to make them more understandable. These changes are made automatically during the upgrade process.

Changes to settings on the Edit Group Management Service page in the Administration Console are summarized in the following table.

Table 1-1 GMS Administration Console Settings Changes from 2.1.1 to 4.0

The Merge Protocol settings from Sun GlassFish Enterprise Server v2.1.1 are not supported and have been removed.

Application Client Interoperability

The Jakarta EE 10 platform specification imposes stricter requirements than Java EE 5 and older did on which JAR files can be visible to various modules within an EAR file. In particular, application clients must not have access to EJB JAR files or other JAR files in the EAR file unless they use a Class-Path header in the manifest file, or unless references use the standard Java SE mechanisms (extensions, for example), or use the Jakarta EE library-directory mechanism. Deployed Java EE 5 applications that are upgraded to Eclipse GlassFish 7 will have the compatibility property set to v2 and will run without change on Eclipse GlassFish 7. You may, however, want to consider modifying the applications to conform to Jakarta EE 10 requirements.

If your upgrade includes a deployed application with an application client, you will need to retrieve the client stubs using Eclipse GlassFish 7 in order to run the client. Use the asadmin get-client-stubs command.

If you try to run the application client before retrieving the client stubs, you will see the following error message:

Invalid or corrupt jarfile jar-file-name

If you commonly distribute application clients to remote systems from which users will run them, you must not only retrieve the client stubs, but you must also run the package-appclient utility for Eclipse GlassFish 7 to upgrade the Eclipse GlassFish system files. This utility creates a JAR file, which you can then expand on the remote systems.

Application clients use EJBs, web services, or other enterprise components that are in the application server (on the server side). The application client and the application server must use the same version and implementation of the RMI-IIOP protocol. Eclipse GlassFish 7 does not support communication between different versions of the protocol implementation. You cannot run application clients with one version of the application server runtime with a server that has a different version. Most often, this would happen if you upgraded the server but had not upgraded all the application client installations. If you run the package-appclient utility, this issue will not arise.

You can use the Java Web Start support to distribute and launch the application client. If the runtime on the server has changed since the end-user last used the application client, Java Web Start automatically retrieves the updated runtime. Java Web Start enables you to keep the clients and servers synchronized and using the same runtime.

Node Agent Support

Eclipse GlassFish 7 does not support node agents. When updating from installations of earlier product versions in which node agents were configured, the cluster definitions will be migrated, but the clustered instances themselves must be manually re-created. See Correcting Cluster configuration for more information.

HADB and hadbm Command Support

Eclipse GlassFish 7 does not support HADB or the hadbm management command.

Instead of HADB, Eclipse GlassFish 7 supports high availability clustering by means of in-memory session state replication and ActiveCache for GlassFish. See " High Availability in Eclipse GlassFish" in Eclipse GlassFish High Availability Administration Guide for more information.

Command Line Interface: The asadmin Command

The following sections describe changes to the command line utility asadmin:

For more information about asadmin and its subcommands, see the Eclipse GlassFish Reference Manual.

Deprecated asadmin Subcommands

In Eclipse GlassFish 7, it is recommended that utility options of the asadmin command precede the subcommand. Utility options are options that control the behavior of the asadmin utility, as distinguished from subcommand options. Use of the following options after the subcommand is deprecated and will be removed in Eclipse GlassFish 7.1.0.

  • --host

  • --port

  • --user

  • --passwordfile

  • --terse

  • --secure

  • --echo

  • --interactive

Replaced by an operand in the list-custom-resources subcommand and the list-jndi-entries subcommand.

Applications That Use Java DB

The directory location of Java DB in Eclipse GlassFish 7 has changed from its location in previous installations. Suppose that you have deployed applications that use Java DB databases in your previous server installation, and you upgrade your existing installation to Eclipse GlassFish 7. If you run the asadmin start-database command and successfully start Java DB, you could run into problems while trying to run applications that were deployed on your previous server installation.

To solve this problem, you can copy the databases directory from your previous installation to as-install/databases. Make sure the database is not running when you do this.

Alternatively, you can perform these steps:

  1. Use the asadmin start-database command with the --dbhome option pointing to the databases directory in the older version of Java DB. For example:

    asadmin start-database --dbhome c:\glassfish\databases

  2. After upgrade, start Eclipse GlassFish 7.

Applications That Use Persistence

Eclipse GlassFish 7 and 3.0.1, and Sun GlassFish Enterprise Server v3 use the persistence provider EclipseLink, while earlier versions used TopLink Essentials.

An application that uses the container to create an EntityManager or EntityManagerFactory and that used Toplink Essentials as its provider will work in Eclipse GlassFish 7. The container creates an EntityManager if the application uses the @PersistenceContext annotation to inject an EntityManager, as in the following example:

@PersistenceContext
EntityManager em;

The container creates an EntityManagerFactory if the application uses the @PersistenceUnit annotation to inject an EntityManagerFactory, as in the following example:

@PersistenceUnit
EntityManagerFactory emf;

EntityManager em = emf.createEntityManager();

When the application is loaded, Eclipse GlassFish 7 will translate the provider to EclipseLink and will also translate toplink.* properties in the persistence.xml to corresponding EclipseLink properties. (The actual persistence.xml file remains unchanged.)

Under certain circumstances, however, you may have to modify the persistence.xml file or your code:

  • If your application uses Java SE code to create the EntityManagerFactory, you will need to change your persistence.xml file for both the provider element and for any toplink.* properties to use the EclipseLink equivalents. An application uses Java SE code if it uses the javax.persistence.Persistence class to create the EntityManagerFactory, as in the following example:

    EntityManagerFactory emf =
    javax.persistence.Persistence.createEntityManagerFactory("Order");
EntityManager em = emf.createEntityManager();

    In this case, change the provider element to specify the following:

    <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>

  • If the application itself contains any TopLink Essentials-specific code and therefore contains casts to oracle.toplink.*, you must change the code to cast to org.eclipse.persistence.*. You can use the package renamer tool described on the Eclipse wiki to do this. This tool is not provided with Eclipse GlassFish 7, however, so you must obtain it from the EclipseLink project download site.

HTTP Service to Network Service Changes

In Eclipse GlassFish 7, most HTTP Service settings are defined in the Network Service configuration that was introduced in Sun GlassFish Enterprise Server v3.

The changes are described in the following sections.

Changes to Dotted Names

The dotted name hierarchy for the HTTP Service configuration in Eclipse GlassFish 7 is shown below. Elements that are no longer supported are request-processing, keep-alive, connection-pool, http-protocol, http-file-cache, and http-listener. During the upgrade process, these discontinued elements are remapped to the new configuration automatically and then deleted.

config
    http-service
        access-log
        request-processing
        keep-alive
        connection-pool
        http-protocol
        http-file-cache
        http-listener
            ssl
            property
        virtual-server
            http-access-log
            property
        property
    thread-pools
        thread-pool

The dotted name hierarchy for the Eclipse GlassFish 7 Network Service and HTTP Service configurations is shown below. The network-config element and all its children are new except for ssl.

config
    network-config
        transports
            selection-key-handler
            transport
        protocols
            protocol
                http
                    file-cache
                port-unification
                    protocol-finder
                protocol-chain-instance-handler
                    protocol-chain
                protocol-filter
                ssl
        network-listeners
            network-listener
    http-service
        access-log
        virtual-server
            http-access-log
            property
        property
    thread-pools
        thread-pool

The following example compares the commands for setting a listener port for Sun GlassFish Enterprise Server v3 and Eclipse GlassFish 7. Note that the configuration for Enterprise Server v3 also applies to all earlier Enterprise Server 2.x releases.

  • Command for Sun GlassFish Enterprise Server v3 and earlier:

    asadmin set server-config.http-service.http-listener.http-1.listenerport=4321

  • Command for Eclipse GlassFish 7:

    asadmin set server-config.network-config.network-listeners.network-\
listener.http-1.listenerport=4321

Changes to asadmin Subcommands

To accommodate the move of HTTP Service into the new Network Service configuration, asadmin subcommands are changed as follows:

  • The create-ssl subcommand has a new --type parameter value, network-listener.

  • The create-virtual-server SUBcommand has a new parameter, --networklisteners.

  • The create-http-listener subcommand adds a network-listener element to the domain configuration. The syntax and options of this commands are unchanged.

Remapping of HTTP Service Attributes and Properties

The following tables describe how attributes and properties in the HTTP Service configuration for Eclipse GlassFish 7 are remapped to attributes in the Network Service configuration for older product releases. If you use a configuration from a Sun GlassFish Enterprise Server v2 or v3 release, this remapping happens automatically and then discontinued elements are deleted.

NSS Cryptographic Token Support

Eclipse GlassFish 7 does not support Network Security Services (NSS) cryptographic tokens. When upgrading to Eclipse GlassFish 7 from Enterprise Server v2.x, additional manual configuration steps must be performed. These steps are explained later in this guide, in Upgrading Installations That Use NSS Cryptographic Tokens.
