Singkatnya: Saya membuat panggilan JNDI jarak jauh untuk kacang stateless dari satu server Websphere ke server lainnya (profil berbeda di JVM berbeda pada mesin yang sama) tetapi setelah panggilan selesai, InitialContext berubah dan saya tidak dapat lagi mengakses kacang lokal saya .
Situasinya adalah sebagai berikut:
Server Websphere Server1 memiliki aplikasi kompleks dengan banyak kacang dan juga perlu mengakses kacang stateless (BeanX) di Websphere Server2 yang menjalankan aplikasi lain.
Saya telah berhasil mengakses BeanX di Server2 menggunakan salah satu dari dua metode:
Koneksi melalui kode:
private static Context; static { Hashtable env = new Hashtable(); env.put(Context.INITIAL_CONTEXT_FACTORY, com.ibm.websphere.naming.WsnInitialContextFactory"); env.put(Context.PROVIDER_URL, "iiop://localhost:9101"); try { ctx = NamingManager.getInitialContext(env); mgr = (RemoteBeanXManager) PortableRemoteObject.narrow(ctx.lookup("BeanXManagerBean/remote"), RemoteBeanXManager.class); } catch (NamingException e) {//logging } }- Koneksi melalui konfigurasi Webshere Dikonfigurasi di Server1: Lingkungan -> Penamaan -> Pengikatan Ruang Nama -> Baru ... Tidak Langsung Dan memperkenalkan nilai yang diperlukan, sesuai dengan kacang yang diekspos dari Server2.
URL Penyedia:corbaloc:iiop:localhost:9101
Konteks awal nama pabrik:com.ibm.websphere.naming.WsnInitialContextFactory
Dan kemudian melanjutkan untuk mendapatkan kacang dalam kode seolah-olah itu dalam konteks lokal saya.
Saya menghapus keamanan untuk RMI/IIOP untuk Keluar di Server1 dan untuk Masuk di Server2, sehingga server dapat berkomunikasi.
Kacang diekspos oleh Server2, antarmuka jarak jauh RemoteBeanXManager ada dalam paket umum untuk kedua aplikasi dan panggilan berlanjut melalui dengan benar.
Masalah muncul setelah panggilan, ketika injeksi EJB berikutnya di Server1 untuk kacang lokal mengembalikan com.ibm.ejs.container.util.ExceptionUtil.NoSuchEJBException
Pada dasarnya, pada anotasi @EJB berikutnya yang ditemui, Server1 akan menampilkan:
com.ibm.ejs.container.EJBNotFoundException: EJB bernama SomeOtherBean tidak ada di aplikasi Aplikasi Perusahaan Saya. di com.ibm.ejs.container.HomeOfHomes.resolveEJBLink(HomeOfHomes.java:751)
Apa yang berhasil saya pahami saat saya selidiki, adalah bahwa InitialContext di Server1 diubah oleh koneksi ke Server2, dan tidak dapat 'direset' kembali setelah panggilan melalui antarmuka jarak jauh. Saya mencoba mendapatkan kembali InitialContext dengan pengaturan default setelah manajer jarak jauh diperoleh, tetapi tidak berhasil.
Saya mencoba menambahkan parameter konfigurasi opsional:
com.ibm.websphere.naming.jndicache.cachename providerURL
com.ibm.websphere.naming.jndicache.cacheobject none
Masih pengecualian yang sama.
Jika Anda mempunyai ide tentang cara mengisolasi/cache konteks di Server1 sehingga dapat melanjutkan operasi normal setelah panggilan RMI-IIOP, beri tahu saya
Diperbarui untuk ditambahkan:
Saat saya mengomentari kode yang melakukan panggilan jarak jauh, aplikasi dimulai dengan benar, dan semua injeksi @EJB berfungsi.
Di Server2, saat pemanggilan metode dari Server1 - tidak terkecuali, hanya pesan-pesan berikut:
