Siteadmin, content pages blank

Can you share the STR ? what did you do exactly ?

Sorry, you've lost me there. Whats the STR?

The problem started when I installed a custom package using this tutorial, https://helpx.adobe.com/experience-manager/using/custom-sling-servlets.html

Adobe Experience Manager Help | Submitting Adobe Experience Manager form data to Java Sling Servlets

The package installed just fine but siteadmin disappeared. I've deleted the package on system/console, deleted the clientlib folder based on a suggestion in the forum. Thats about it.

What version of AEM are you using, because the above package is supported till 6.2. By STR i mean steps to reproduce. Apology my bad.

No problem. I'm on 6.2.

As I mentioned before, I created a package for Maxmind GeoIP2 using the tutorial link. Package was installed without problems on the system console. After restarting the instance, i noticed I couldn't access siteadmin. I delete the bundle, didn't help

I am not able to reproduce the issue. It works fine . Let me drill down to the above logs

That package contains a JSP that implements a basic form and a clientlib. Nothing in that would cause site admin to disappear.

Package works fine on 6.2 - been tested many times. See below

For your issue - can you access the Felix web console to see the OSGi bundles?

You stated:

" I created a package for Maxmind GeoIP2 using the tutorial link"

In which tutorial does it use Maxmind GeoIP2?

For better context, please see this AEM not working with GeoIP2 databasereader  question which I asked last week which you helped me out with. I was using the Maxmind GeoIP2 db and needed to build an OSGI package for it using the instructions on the tutorial. I built the package and installed it. Something went wrong after that, siteadmin, login, content pages don't work. Crxde, system console pages are working

Now I rememeber that. I answer many question each week. Anyhow - I pointed you to the Servlet article as an example of how to wrap 3rd party  JAR files into an OSGi bundle using an Eclipse plug-in project. IN the Servlet article - we wrap the SIMPLE JSON JAR.

Now for your issue - I am wondering if the cause of the issue is the GEO JAR files. How many JAR files did you try and place into the OSGi bundle?

There were 11 jar files in the bundle. I've tried disabling and deleting the bundle. Doesn't make a difference
