J2ME Characteristics and architecture• Java Virtual Machine
– Virtual Hardware (Processor)– KVM (K Virtual Machine)
• Min. 128 kByte, typ. 256 kByte• Optimized for low performance devices• Might be a co-processor
• Configurations– Subset of standard Java libraries depending
technical hardware parameters (memory, CPU)– CLDC (Connected Limited Device Configuration)
• Basic libraries, input/output, security – describes Java support for mobile devices
• Profiles– Interoperability of heterogeneous devices
belonging to the same category– MIDP (Mobile Information Device Profile)
• Defines interfaces for GUIs, HTTP, application support, …
