内容图文

我使用Eclipse的单个工作区在同一工作区中有两个项目.

Project1 – 引用项目#2,还包含项目2的“Java构建路径”
Project2 – 没有引用任何内容

Project1包称为Project1
Project2 pacakge被称为Proejct2

我使用以下方法将Projec2导入Project1：

import Project2.ClassName 

编译时我收到错误：

Error preverifying class Project1.Launcher    Project1 line 0    BlackBerry Java Problem
Error!: Error: preverifier failed: C:\Users\footose\Desktop\eclipse\plugins\net.rim.eide.componentpack4.5.0_4.5.0.16\components\bin\prev ...    Project1        line 0    BlackBerry Java Problem 

任何建议都会很棒

解决方法:

这可能是因为您正在使用的net.rim.eide库中未正确完成预验证步骤.
这个帖子实际上建议到preverify the library independently,甚至为每个班级做预先验证过程(如here所做)！

注意：preverification是：

a phase in the development and deployment cycle for Java applications designed to run on the 07003 (Connected Limited Device Configuration).

Preverification performs certain checks on the Java bytecodes ahead of runtime.
If this first verification pass is ok, the preverifier annotates the classfiles (using standard Java bytecode “attributes”, so that these are still plain old Java bytecodes and will be executable in VMs not aware of the benefits of preverification), and then saves the annotated class files or passes them along to the next tool in the compile chain.

When the 07004 attempts to run execute a J2ME CLDC-based application, it checks the Java class files for these preverification annotations. Proper annotations in the class files guarantee that certain compile-time checks were made, and so the KVM can pass through its own verfication and security checks much faster and start executing the application more quickly.

Sun’s CLDC reference implementation SDK includes the ‘preverify’ tool. You use the tool after compiling your code via javac (or your favorite Java compiler).
