AEM 6.0 Installation Error

[maheshgundre]

Hi,

I installed AEM 6.0 on Centos latest version 7 64 bit.

After installation done , am getting the below error.

Unable to compile class for JSP: An error occurred at line: 95 in the jsp file: /libs/granite/core/components/login/login.jsp The type java.lang.CharSequence cannot be resolved.

Java 1.8 installed and variables also set in /root/.bash_profile

Please do the needful.

Thanks & Regards,

Downgrade jdk to 1.7 , install sp1 & then upgrade jdk to 1.8

I got the same error. In my case JDK 1.8 was already installed on machine because of which AEM 6.0 was not working.

-- I install JDK 1.7

-- Uninstall JDK 1.8. Deleted the crx-quickstart folder.

-- Start new instance of AEM 6.0. It worked :)

On Mac Os X if you run java version 1.8:
1. Download AEM 6.0 Service Pack 2-1.0: http://docs.adobe.com/docs/en/aem/6-0/release-notes-sp2.html (follow the download link)
2. Unzip AEM 6.0 Service Pack 2-1.0 zip file.
3. Create a new folder called "install" in the root of the folder: crx-quickstart
4. Copy the content inside AEM 6.0 Service Pack 2-1.0 foldern ( 2 folders: jcr_root & META-INF) into install foldern
5. Run the  cq-quickstart-6.0.0. again. Now it should work again!

My login was change after the update back to the default: admin | admin

Read the supported platform docs listed here:

What if you're getting this error and you're still on Java 1.7?

[eulered]

The same exception on Mac OS Yosemite 10.10 with idk 1.7.0_71 and jdk 1.8.0_25.

I've just found a fix for this that worked for me. I was having the same error using jdk1.7.0_80.jdk.

I was looking for ways to switch Java easily and found this: http://www.jayway.com/2014/01/15/how-to-switch-jdk-version-on-mac-os-x-maverick/

So I added this to my bash profile:

function setjdk() {
  if [ $# -ne 0 ]; then
   removeFromPath '/System/Library/Frameworks/JavaVM.framework/Home/bin'
   if [ -n "${JAVA_HOME+x}" ]; then
    removeFromPath $JAVA_HOME
   fi
   export JAVA_HOME=`/usr/libexec/java_home -v $@`
   export PATH=$JAVA_HOME/bin:$PATH
  fi
}
function removeFromPath() {
  export PATH=$(echo $PATH | sed -E -e "s;:$1;;" -e "s;$1:?;;")
}
setjdk 1.7

Now my version of CQ5 works with Java 1.6. 1.7 and 1.8.

So it must have been something to do with multiple versions of Java in the PATH conflicting.
