I am trying "Spring in Action" chapter4 example

when i am trying to implements BeforeAdvice, it shows following error in eclipse

- The hierarchy of the type AudienceAdvice is inconsistent
- The type org.aopalliance.aop.Advice cannot be resolved. It is indirectly referenced from
required .class files

I have included all libraries of spring-framework-3.0.3.RELEASE and asm-all-3.2.jar,commons-logging-1.1.1.jar.

Could anyone suggest me how to rectify this error in eclipse as i am not able to build.

Any help in this regard would be highly appreciated

This code works fine with one input but doesn't work for more than one input.
Scenario 1:Working
input:<Value>test for < syntax</value>
output:<Value>test for <lt; sysntax</value>

Scenario 2:not Working
input:<Value>test for < syntax</value><Value>test for < syntax</value>
output:<Value>test for <lt; syntax</value><Value>test for <lt; syntax</value>

but this is giving wrong result.
Any suggestion

I have tried like this but replacing the string back to original string is very tedious.

how do you use boundary to achieve this

Input:<A name="123<45" />
desired output:<A name="123<lt&45"/>

In general, an exception happens because some resource is not available or some other condition required for correct execution is not present

A checked exception must be caught somewhere in your code. If you invoke a method that throws a checked exception but you don't catch the checked exception somewhere, your code will not compile. That's why they're called checked exceptions; the compiler checks to make sure that they're handled or declared.

A runtimeException is not handled by compiler, it could come as a programming logic, like if you try to access array element, which index is greater than the size of array(ArrayIndexOutOfBound Exception). So user has to handle this kind of exception by his/her logic.If not, the program will not execute at runtime.

One more thing checked exception is handled at compile time(when you try to compile your file for ex javac filename), but runtime exception will occur at runtime(when you execute your program for ex Java filename)
