Ill-advised or mistaken usage of a core class (java.* or javax.*) Conversion to Dalvik format fail

在编译导入的工程时出现了如下错误，clean了再build all都没问题，run就会报如下错误：

 trouble processing "javax/sql/RowSet.class":

Ill-advised or mistaken usage of a core class (java.* or javax.*)
when not building a core library.

This is often due to inadvertently including a core library file
in your application's project, when using an IDE (such as
Eclipse). If you are sure you're not intentionally defining a
core class, then this is the most likely explanation of what's
going on.

However, you might actually be trying to define a class in a core
namespace, the source of which you may have taken, for example,
from a non-Android virtual machine project. This will most
assuredly not work. At a minimum, it jeopardizes the
compatibility of your app with future versions of the platform.
It is also often of questionable legality.

If you really intend to build a core library -- which is only
appropriate as part of creating a full virtual machine
distribution, as opposed to compiling an application -- then use
the "--core-library" option to suppress this error message.

If you go ahead and use "--core-library" but are in fact
building an application, then be forewarned that your application
will still fail to build or run, at some point. Please be
prepared for angry customers who find, for example, that your
application ceases to function once they upgrade their operating
system. You will be to blame for this problem.

If you are legitimately using some code that happens to be in a
core package, then the easiest safe alternative you have is to
repackage that code. That is, move the classes in question into
your own package namespace. This means that they will never be in
conflict with core system classes. JarJar is a tool that may help
you in this endeavor. If you find that you cannot do this, then
that is an indication that the path you are on will ultimately
lead to pain, suffering, grief, and lamentation.

网上很多说如何导入

但是我都做了还是没有用，解决办法如下：

主要是要把你要添加的jar文件以

工程名->build path->config build path

remove 然后再add Library->user library->next->user librarys->new

记得要勾选system library

这样添加了就能编译run过去生成apk了

折腾了我大半天，各种办法。。。。。。。。。

 

这个博文里面详细说明了如何导入系统应用到eclipse
