Weblogic 10.3 and commons-lang-2.4.jar

Question

Dear All,
I made a web application. It uses some 3party libraries, they are in web-inf/lib directory:
WEB-INF
|-sun-web.xml
|-web.xml
|-weblogic.xml
WEB-INF/lib
|-commons-io-1.4.jar
|-commons-lang-2.4.jar
|-xbean.jar
My web application is running on Glassfish application server. When I tried to to deploy it to Weblogic 10.3 server I got follow error message:
java.lang.NoSuchMethodError: org.apache.commons.lang.StringUtils.containsIgnoreCase(Ljava/lang/String;Ljava/lang/String;)Z
     at hu.mol.eai.fileadapter.web.PollingTask.getJTAClass(PollingTask.java:589)
The reason of the exception: there is an older version of commons-lang library in classpath and the application server loaded this library on startup. I found library in /bea_10.3/modules/com.bea.core.apache.commons.lang_2.1.0.jar.
If I delete it and the newer version of library (commons-lang-2.4.jar) copy to the /bea_10.3/modules/ directory my web application is working.
I think this solution is a hacking, because I overwrite an original library of application server. I is not too nice solution for a big company environment where there is a support agreement with Weblogic partner.
Could you give me a good / nicer solution?
thank you, zappee

Thank you for your answer.
And what can I do if my war file is in an ear file?
Structure of my enterprise application:
*.ear
|-lib\commons-lang-2.4.jar
|-lib\....jar
|
|-FileAdapterWeb.war
|-FileAdapterCommons.jar
|-FileAdapterPlugins.jar
|-schema.jar
|- ...
I do not want to put commons-lang-2.4.jar into *.war and lib directory same time. The all components of my enterprise applications are going to use commons-lang-2.4.jar. For example: it uses FileAdapterWeb.war and FileAdapterPlugins.jar too.
Is there a solution for me?
