[smacdonald2008]

Please describe how you are trying to access. Are you doing to access via CRXDE lite, code, etc? 

[krishnak3067714]

No. Through Web Console: OSGI --> Components

Thanks,

Krish

Hi,

what version of AEM are you using? Which servicepacks/hotfixes? What have you done before (deployed hotfixes or anything like this)? Have you restarted the instance? Is this happening only on a single instance or is throughout all your instances?

Jörg

[krishnak3067714]

I'm using AEM 6.1 and This is happening to only one instance. I restarted it. Still same issue. Other instances are good.

[joshua_hansen]

I'm experiencing the same after doing some custom rewriter work, not sure if its related or not quite yet, I'm still working on the problem. Was there ever a solution found in your case?

[joshua_hansen · Accepted solution]

Well, in case it helps anyone else ... I fixed my specific issue, although after researching it, I feel that ultimately the cause will vary - here is what solved my issue.

Tailing the error.log, I stopped the "org.apache.felix.webconsole.plugins.ds" bundle, then restarted it. It threw the following notice (note it's an INFO log, not a WARN or ERROR)

12.12.2015 00:13:53.368 *INFO* [OsgiInstallerImpl] org.apache.sling.installer.core.impl.tasks.BundleInstallTask Exception during install of bundle TaskResource(url=jcrinstall:/apps/system/install/aem-sightly-ide-api-0.1.0-SNAPSHOT.jar, entity=bundle:aem-sightly-ide-api, state=INSTALL, attributes=[Bundle-Version=0.1.0.SNAPSHOT, Bundle-SymbolicName=aem-sightly-ide-api, org.apache.sling.installer.api.tasks.ResourceTransformer=:30:36:32:], digest=1449874117952) : Bundle installation rejected by hook.. Retrying later. org.osgi.framework.BundleException: Bundle installation rejected by hook. at org.apache.felix.framework.Felix.installBundle(Felix.java:3123) at org.apache.felix.framework.BundleContextImpl.installBundle(BundleContextImpl.java:167) at org.apache.sling.installer.core.impl.tasks.BundleInstallTask.execute(BundleInstallTask.java:47) at org.apache.sling.installer.core.impl.OsgiInstallerImpl.doExecuteTasks(OsgiInstallerImpl.java:847) at org.apache.sling.installer.core.impl.OsgiInstallerImpl.executeTasks(OsgiInstallerImpl.java:689) at org.apache.sling.installer.core.impl.OsgiInstallerImpl.run(OsgiInstallerImpl.java:265) at java.lang.Thread.run(Thread.java:745)

After uninstalling that offending bundle "aem-sightly-ide-api", and restarted the "org.apache.felix.webconsole.plugins.ds" bundle, things worked as expected (and the bundle I deleted was re-installed, apparently via the "org.apache.felix.webconsole.plugins.ds" bundle startup.

It's also happening to me. Any solution to this problem?

Any other solution to this problem? 

I'm working with AEM 6.1
