Please suggest a API that开发者_JAVA百科 can let me do the barcode read in mobile for J2ME..
There's a related post on doing this on Android: Using ZXing to create an android barcode scanning app
Update: As bhakki pointed out, you are asking about J2ME. The ZXing library appears to have partial support for J2ME: http://code.google.com/p/zxing/, so this other post may be of use still. Of course, this assumes you are using a mobile device with a camera
Update2: Specific J2ME code can be found in their SVN repository: http://code.google.com/p/zxing/source/browse/trunk#trunk%2Fjavame%2Fsrc%2Fcom%2Fgoogle%2Fzxing%2Fclient%2Fj2me%253Fstate%253Dclosed ... and their forums may be of use: https://groups.google.com/group/zxing/search?group=zxing&q=javame&qt_g=Search+this+group
