Your CAS server has two copies of the apache commons jar and it’s using one that does have a the required method. Check your CAS lib directory and make sure you have distinct jars. Exclude the rest from your build.

Jay,

 

I had the same issue with the RestAPI on CAS 4.0 and it was because the CAS lib had commons-lang-2.1.jar and commons-lang-2.5.jar (like Misagh said below).  I had to exclude the commons-lang-2.1.jar using the pom.xml file.  If you are curious, I added this line to my maven-war-plugin in the pom.xml file:

 

            <plugin>

                <groupId>org.apache.maven.plugins</groupId>

                <artifactId>maven-war-plugin</artifactId>

                <version>2.3</version>

                <configuration>

                    <warName>cas</warName>

                    <overlays>

                        <overlay>

                            <groupId>org.jasig.cas</groupId>

                            <artifactId>cas-server-webapp</artifactId>

                        </overlay>

                    </overlays>

                    <packagingExcludes>WEB-INF/lib/commons-lang-2.1.jar</packagingExcludes>

                </configuration>

            </plugin>

Hi David / Misgah

Many thanks for the help.

I have just one version of all files in my WEB-INF/lib

I have this problem only on Weblogic but works fine on Tomcat. 

Cheers

Jay

Well then you must have a classloader issue. Weblogic might have an older copy of that JAR that it’s putting on the classpath for you.

Hi Misagh

Many thanks....that error has gone now on weblogic too ... I have prepend the classpath with that jar as below in setDomainEnv.cmd 

set PRE_CLASSPATH=C:\libs\commons-io-2.4.jar

Thanks

Jay
