J2 EE yog plaub- qib architecture. Cov no suav nrog Client Tier (Kev nthuav qhia qib los yog Daim Ntawv Thov qib ), Web qib , Enterprise JavaBeans Tier (los yog Application server qib ), thiab Enterprise Information Systems Tier los yog Data qib.
Xav txog qhov no, Tier hauv Java yog dab tsi?
Java EE Technologies Siv hauv Web Tier Ib tus neeg siv-interface tivthaiv lub hauv paus rau cov ntawv thov web uas tso cai rau koj suav nrog UI cov khoom (xws li cov teb thiab cov nyees khawm) ntawm nplooj ntawv, hloov thiab siv tau cov ntaub ntawv UI tivthaiv, txuag UI cov ntaub ntawv rau cov khw muag khoom rau cov ntaub ntawv sab nraud, thiab tswj cov khoom hauv lub xeev.
Ib yam li ntawd, tus neeg siv khoom qib yog dab tsi? Cov neeg tier muaj daim ntawv thov cov neeg siv khoom uas nkag mus rau Java EE server thiab uas feem ntau nyob ntawm lub tshuab sib txawv ntawm lub server. Cov cov neeg siv khoom ua kev thov rau lub server. Lub server ua cov lus thov thiab xa cov lus teb rov qab rau lub tus neeg siv khoom.
Ua li no, j2ee technologies yog dab tsi?
Cov thev naus laus zis tseem ceeb hauv J2EE platform yog:
- Java API rau XML-Based RPC (JAX-RPC)
- JavaServer Pages.
- Java Servlets.
- Enterprise JavaBeans Cheebtsam.
- J2EE Connector Architecture.
- J2EE Management Model.
- J2EE Deployment API.
- Java Management Extensions (JMX)
Dab tsi yog j2ee hauv Java nrog piv txwv?
J2 EE yog lub platform-yooj yim, Java -centric ib puag ncig los ntawm Sun rau kev tsim, tsim thiab xa tawm Web-based enterprise applications online. Cov J2 EE platform muaj ib txheej ntawm cov kev pabcuam, APIs, thiab cov txheej txheem uas muab kev ua haujlwm rau kev tsim cov kev siv ntau yam, Web-based applications.

Yuav ua li cas yog ib tug txheej txheem nyob rau hauv lub operating system dab tsi yog ib tug xov nyob rau hauv lub operating system?
Ib tug txheej txheem, nyob rau hauv cov nqe lus yooj yim tshaj, yog ib tug executingprogram. Ib tug los yog ntau tshaj threads khiav nyob rau hauv cov ntsiab lus ntawm cov txheej txheem. Ib tug xov yog ib qho tseem ceeb chav tsev uas theoperating system faib lub sij hawm processor. Lub threadpool feem ntau yog siv los txo tus naj npawb ntawm cov ntaub ntawv thov thiab muab kev tswj hwm ntawm cov neeg ua haujlwm threads
Dab tsi yog txoj hauv kev virtual thiab txoj hauv lub cev hauv asp net?
Ua ntej tshaj, cia peb tau txais cov ntsiab lus ntawm ob qho tib si. Txoj kev lub cev - Qhov no yog txoj hauv kev tiag tiag cov ntaub ntawv nyob ntawm IIS. Txoj kev Virtual - Qhov no yog txoj hauv kev kom nkag mus rau cov ntaub ntawv uas tau taw qhia los ntawm sab nraud ntawm IIS daim ntawv thov folder
Dab tsi yog 3 tier architecture nrog piv txwv?
Piv txwv ntawm 3-tier architecture: JReport. Cov qauv tsim rau kev xa tawm 3-tierarchitecture yuav muaj qhov kev nthuav qhia tierdeployed rau lub desktop, laptop, ntsiav tshuaj lossis mobile ntaus ntawv los ntawm aweb browser lossis web-based application siv webserver
Dab tsi yog qhov tsis muaj dab tsi hauv Java?
Pej xeem txhais tau hais tias txoj kev pom thiab tuaj yeem raug hu los ntawm lwm yam khoom ntawm lwm hom. Lwm cov kev xaiv yog tus kheej, tiv thaiv, pob thiab pob-private.Qhov no txhais tau hais tias koj tuaj yeem hu rau txoj kev zoo li qub yam tsis muaj kev tsim anobject ntawm chav kawm. void txhais tau hais tias txoj kev tsis muaj nqi
