Problem:

Javaweb project in myclipse spirng configuration file XML has a small red fork

problems:referenced file contains errors (http://www.springframework.org/schema/beans/spring-beans-3.0.xsd).

Solve:
Option one: Eclipse in selected items Click Progect–>clean Clean up, delete cache.
Method Two: This is due to the buffer caused by the related configuration and the current definition of conflict, the solution is to clear the cached information,

    1: Open Preferences-> General-> Network Connections-> Cache:

    2: Select All, then click the button Remove All button.
    Project Normal

Option three:
Remove the checkmark before the "honour all XML Schema locations" in Preferences > XML > XML Files > Validation. It disables validation that points to the same namespace references in different schema locations, only as a result of the verifiable XML file found for the first time.

Solution one or two cannot solve the time, the time method three, may solve.
