is already been used by another package at location package

异常如下：
为什么会是同一工程的tmp下的和deploy下的有冲突，这是咋回事？

这个问题我也遇到了，估计是和编译的选型有关系。我后来把工程的source的编译产物由默认的build\classes修改到webinfo的classses目录下，就解决这个问题了。

我用eclipse直接在tomcat里调式也是这样
打包部署到是可以
不知道为什么

http://www.mathworks.com/matlabcentral/fileexchange/25986-constrained-particle-swarm-optimization Description Previously titled "Another Particle Swarm Toolbox" Introduction Particle swarm optimization (PSO) is a derivative-free global optimum solver. It is inspired by the surprisingly organized behaviour of large groups of simple animals, such as flocks of birds, schools of fish, or swarms of locusts. The individual creatures, or "particles", in this algorithm are primitive, knowing only four simple things: 1 & 2) their own current location in the search space and fitness value, 3) their previous personal best location, and 4) the overall best location found by all the particles in the "swarm". There are no gradients or Hessians to calculate. Each particle continually adjusts its speed and trajectory in the search space based on this information, moving closer towards the global optimum with each iteration. As seen in nature, this computational swarm displays a remarkable level of coherence and coordination despite the simplicity of its individual particles. Ease of Use If you are already using the Genetic Algorithm (GA) included with MATLAB's Global Optimization Toolbox, then this PSO toolbox will save you a great deal of time. It can be called from the MATLAB command line using the same syntax as the GA, with some additional options specific to PSO. This will allow a high degree of code re-usability between the PSO toolbox and the GA toolbox. Certain GA-specific parameters such as cross-over and mutation functions will obviously not be applicable to the PSO algorithm. However, many of the commonly used options for the Genetic Algorithm Toolbox may be used interchangeably with PSO since they are both iterative population-based solvers. See >> help pso (from the ./psopt directory) for more details. Features * NEW: support for distributed computing using MATLAB's parallel computing toolbox. * Full support for bounded, linear, and nonlinear constraints. *

同一工程下的冲突问题问题出现在将同一个项目移动另一个·eclipse编译器中运行后编译器中有一串简单的英语短句： ....is already been used by another package at location package 解决方式：我把工程的source的编译产物由默认的build\classes修改到webinfo的classses目录下

在配置struts2里面的package节点时，如果重名会报如下错误：严重: Exception starting filter struts2 The package name 'mystruts' at location package - file:/D:/Tomcat%206.0/webapps/TestProc/WEB-INF/classes/struts.xml:14:74 is...

今天做项目需要用到json包，于是就将struts2与json整合，结果启动tomcat的时候发现报如下错误： json包：json-lib-2.1.jar struts2-json-plugin-2.1.8.1.jar jsonplugin-0.34.jar Caused by: The package name 'json-default' at location package...
