electroboy 3 Report post Posted November 25, 2006 (edited) Ok, konsep softwarenya camni.... satu item ada RFID tag. User hanya perlu pin point mobile devices diorang (yg disambung dgn RFID reader dan running the midlet yg jadi UI )..kemudian user boleh store data berkenaan item tu (namaItem, shippingDate blablabla....) based on the unique RFID tag and then masukkan semua record tu dalam javax rms. RFID tu plak padan dgn id dalam RecordStore rms storage tu....so that next time user nak update record simply point the reader to the item RFID tag dan boleh update dgn mudah.Problemnya..... boleh ke RFID reader connect ke handphone/PDA? Aku tanya lecturers dan beberapa kenalan diorang cakap "tak boleh". But then dia cakap konsep tu tak mustahil and try to work that around. So aku nak tanya sesapa yg pernah developed J2ME yg lebih kurang cam aku skang ni? Adakah korang menggunakan RFID sebagai solution or any other better and yet possible/cheap solution?Sbb yg skang dah siap ni kena key in manually di midlet, masuk storage dalam flash memory pastu transfer ke MySQL di PC, pastu manage db di PC tu, bila nak update kena key in id manually.Tp masih belum meet user requirement le, nak simply point to the RFID (or whatever possible solutions) and poof, record berkaitan dipaparkan di form dan sedia untuk diupdate....And then adakah J2ME mampu connect ke RFID reader? sesapa yg tahu please gimme some idea....just your idea and the rest i'll dig it by myself, aku perlukan info utk jumpstart saja..thanks.

syedjr 0 Report post Posted December 5, 2006 (edited) Complicated-nye..Setahu aku J2ME mmg takde fungsi untuk connect RFID reader..wajib guna J2ME ke??Pendapat aku, isu nak connect RFID reader dgn mobile device nie bukan msalah software, tapi lebih kepada masalah hardware.Kalau nak buat jugak, perlu electronically modify samaada RFID reader tu atau mobile device tu sendiri.Modify reader tu supaya transmit guna IR ke, DKU cable ke,bluetooth ke,USB ke..tu kalau nak buat sendiri..kalau nak beli, ada reader yang boleh transmit guna wi-fi, dan memandngkan PDA support wifi, data boleh terus feed ke PDA. Or even better terus ke PC (tapi nie terus bypass J2ME le)Bile dua-dua device (reader dan mobile device) dah boleh "bercakap" guna signal yang sama, baru J2ME bole main peranan (cth read from IR port into RMS, etc)..

Ada idea model lain tak? kalau takleh aku cakap kat user tak boleh la... forum java lain pun tak reply. Takkan takde org terfikir nak buat software camni lagi kut?

Admin2 12 Report post Posted December 9, 2006 hallooo... sorry menyampuk. J2ME tu language untuk buat software hensetkan. boleh tak bagi tau kat mana nak download compiler utk buat software henset. language dia java ngan C++ je ke? Quote Share this post Link to post Share on other sites
electroboy 3 Report post Posted December 9, 2006 (edited) hallooo... sorry menyampuk. J2ME tu language untuk buat software hensetkan. boleh tak bagi tau kat mana nak download compiler utk buat software henset. language dia java ngan C++ je ke?J2ME = java micro edition, so java. (nak guna .net pun boleh, tapi tak panggil j2me la). Kl nak developed j2me di pc ko kena setup development environment java cam biasa (install jdk, set classpath stuffs...) and then setup KVM (midp stuffs...). Utk compile kalau guna compiler javac or IDEs biasa agak tricky sebab cara nak compile j2me tak sama cam j2se. so ko guna J2ME wireless toolkit utk compile and build jar, lagi mudah dan ada default phone emulator skali utk ko test apps ko di PC. Semua software ni ko boleh download di website sun.com. Since topik ni utk solution j2me aku, aku takkan pegi lebih details...tp itulah general idea nya Edited December 9, 2006 by electroboy Quote Share this post Link to post Share on other sites

J2ME ni cam stripped down edition java lor.... Aku masa accept projek memula pikir J2ME ni lebih kurang sama dgn Java... so apa yg java boleh buat aku "nampak" boleh buat di J2ME. But yeah, fair enough... memory and resources mobile device sangat limited. software design strategi aku pun kena ubah sbb faktor niAnyway aku terpaksa cuba cara lain, maybe (somehow) try to take advantage of wifi or bluetooth... so far takde idea lagi. RFID skang everywhere, tp takleh connect ke PDA/handphone plak. Idea yg tgh aku guna skang pun cam doesn't make sense je... konon nak bagi mobile tp baik user carry laptop trus..

unexistance 3 Report post Posted December 11, 2006 since da (macam) tak boleh direct, kena buat lompat2 la kot rfid <--> bluetooth <--> j2mekira midlet ko connect ke satu 'server' rfid yang scan available tags, and display/edit/update..ok ke? huhu..anyway, imho antara pda & handphone, lagi ok pda (buleh sumbat2 kad, macam gps ke ape ke), buleh add functionality dengan (relatively) senang..
