ACS Commons errorpage handler exception

[Balu_M]

Hi All,

I am implementing error redirection functionality in AEM6.1 by using acs-commons package.I am getting below error when i am accessing invalid page in AEM6.1, Can any one help me how to resolve this issue. I amusing acs-commons 2.0.8 version

Caused by: java.lang.Error: Unresolved compilation problems: 
    Only a type can be imported. com.adobe.acs.commons.errorpagehandler.ErrorPageHandlerService resolves to a package
    ErrorPageHandlerService cannot be resolved to a type
    ErrorPageHandlerService cannot be resolved to a type

I will try and reproduce your results - can you post me to the exact URL where you got this code from. I wonder if there is a config issue or a bug somewhere.

Hi Balu,

as you have no doubt done, if you search google there seems to be many reasons for this type of error. Recently I came across this when I migrated some AEM5.6.1 code to AEM6.1

The issue was resolved for me by making sure the import was for the actual class, rather than the package. In your case  com.adobe.acs.commons.errorpagehandler.ErrorPageHandlerService rather than com.adobe.acs.commons.errorpagehandler.*

I would identify the JSP file that is causing the issue, or is the code in the OSGI bundle?

What version of Java are you compiling against? Is it the same version that is being used to run AEM?

Regards,

Opkar

Hi, 

I am using java 1.7 , AEM 6.1.

I am not creating any new files i am using existing 404.jsp in acs-commons package. but when i upload package it not installing jar files available under /acs-commons/install . i installed these two jar files manually through console, is this caused any problem?

acs-aem-commons-bundle-2.0.8.jar -- status of this jar is active

acs-aem-commons-bundle-twitter-2.0.8.jar -- Status is installed

@Balu,

Try re-compiling jsp's from OSGI Felix console. There is a bundle added to jsp compilation. Go to Sling tab -> jsp

Hi Tomar,

Thanks for your help , this issue resolved after compiling the jsp files.

Great :)
