質問

Hibernateを使用していますKARAF 2.3.4コンテナからPostgreSQLに接続しています.Bundleを展開すると、javax.naming.namenotFoundException OSGi：service / javax.sql.DataSource / "（osgi.jndi）という例外があります。 .service.name= JDBC / PostgreSDS）。

これはmy persistance.xmlファイル

です。

<?xml version="1.0" encoding="UTF-8"?>

これは私のblueprint.xmlファイルです：

            </action>

</blueprint>

そしてこれは私のdatasource-postgres.xmlファイル

です。

この問題を解決し、私は言われたM. Cristianとしてのファイルのリストを更新しました。これは他の奇妙な問題です。カラフを再起動し、カラフコンソールを通してデータを挿入しようとすると、コンソールの印刷物はアクティブなトランザクションではありません。 EntityManagerを使用して他の方法を試してみましたが、問題はもう表示されません。

解決

永続ユニットが使用されているのと同じ青写真のコンテキストで公開されているため、コードは機能できません。

問題は、青写真がenitityManagerFactoryサービスを挿入するのを待つことです。そのため、データソースは決して公開されません。ARIES JPAは、バンドルのEntityManagerFactoryを作成する必要があることを検出しますが、データソースを見つけようとしてタイムアウトします。

では、データソースを標識バンドルに入れて作業する必要があります。
