Unable to start AEM instance

[ariellea4070516]

When trying to open my AEM instance I get the following URL response:

http://localhost:4502/libs/granite/core/content/login.html?resource=%2Fcrx%2Fde%2Findex.jsp&$$login$...

When trying to build and deploy my maven project I get an internal server error on http://localhost:4502/crx/packmgr/service.jsp when trying to install the package.

My error log throws the following errors:

Please help!

Hi,

Can you try to login in AEM then do maven deploy. Make sure you define same credentials in pom.xml which have access to login in AEM.

I wish I could. That’s the problem, I can’t even get to the login page because it throws a 500 error.

Did you check this:-cq5 - AEM Error with ExternalLoginModule - Stack Overflow

Or it could be that The LDAPIdentityProvider and ExternalLoginModule configurations haven't been linked properly using the "LDAP Provider Name".

To solve this issue, we need to update the ExternalLoginModuleFactory configuration so it is linked with the LDAPIdentityProvider by the "LDAP Provider Name" value:

1. Go to http://aem-host:port/system/console/configMgr and log in as admin

2. Search for "LdapIdentityProvider" and click on it to open the configuration

3. Note the value in the field "LDAP Provider Name"

4. Search for "ExternalLoginModuleFactory"

5. Make sure the value for "Identity Provider Name" matches the value from step 3.  If it doesn't match then replace the value of "Identity Provider Name" with the value noted in step 3.

6. Save

That's the problem:

You have configured a custom rewriter with the property "generatorType=htmlparser". During load this class is not available. Please check the OSGI console if all bundles are active.

(You can still try to access your instance using the CRX Explorer :$ HOST/crx/explorer/index.jsp)
