[Geoserver-users] NullPointerException and cant obtain envelop of layer-groups.

[Bar-On_Itay]

Dear Geoserver users,

A while ago we had to restart our Geoserver instance (version 2.14.0) and since then I get the following error when trying to view the groups:

org.apache.wicket.WicketRuntimeException: Can’t instantiate page using constructor ‘public org.geoserver.web.data.layergroup.LayerGroupPage()’. An exception has been thrown during construction!

I have reloaded the configuration and catalagus, but still no joy.

If I understand it correctly Geoserver cannot obtain the bounding box of the group layers, but how can I change that?

I have removed the group layers and group sources, but the error still remains.

If anybody can help me out and pointing to a solution, it will be most welcome.

The specific error you are seeing is not familiar to me, but it looks somewhat like a corrupt geoserver configuration.

If this is the case, try looking at each layer group configuration file in your data directory - they will be in the “layergroups” subfolder - and see if you can see anything out of the ordinary. A “normal” layer group configuration can be seen in GeoServer release data directory, for example spearfish.xml

I would also suggest querying the layergroups rest endpoint, to see if you get a different error message that may help narrow down what is causing the problem.

I have reloaded the configuration and catalagus, but still no joy.

If I understand it correctly Geoserver cannot obtain the bounding box of the group layers, but how can I change that?

I have removed the group layers and group sources, but the error still remains.

If anybody can help me out and pointing to a solution, it will be most welcome.

Hi,

I have removed the configuration file of layer group and that seems to have resolved the issue.

Thanks for all the help.

···

The specific error you are seeing is not familiar to me, but it looks somewhat like a corrupt geoserver configuration.

If this is the case, try looking at each layer group configuration file in your data directory - they will be in the “layergroups” subfolder - and see if you can see anything out of the ordinary. A “normal” layer group configuration can be seen in GeoServer release data directory, for example spearfish.xml

I would also suggest querying the layergroups rest endpoint, to see if you get a different error message that may help narrow down what is causing the problem.

I have reloaded the configuration and catalagus, but still no joy.

If I understand it correctly Geoserver cannot obtain the bounding box of the group layers, but how can I change that?

I have removed the group layers and group sources, but the error still remains.

If anybody can help me out and pointing to a solution, it will be most welcome.

I’m glad removing the layer group config worked for you.

Looking at that XML, I don’t see anything odd about it either - my only guess would be one of the styles or layers it references were missing. Regardless, if its working now, I don’t think any other changes are necessary.

Hi,

I have removed the configuration file of layer group and that seems to have resolved the issue.

Thanks for all the help.

Onderwerp: Re: [Geoserver-users] NullPointerException and cant obtain envelop of layer-groups.

The specific error you are seeing is not familiar to me, but it looks somewhat like a corrupt geoserver configuration.

If this is the case, try looking at each layer group configuration file in your data directory - they will be in the “layergroups” subfolder - and see if you can see anything out of the ordinary. A “normal” layer group configuration can be seen in GeoServer release data directory, for example spearfish.xml

I would also suggest querying the layergroups rest endpoint, to see if you get a different error message that may help narrow down what is causing the problem.

Caused by: java.lang.NullPointerException

I have reloaded the configuration and catalagus, but still no joy.

If I understand it correctly Geoserver cannot obtain the bounding box of the group layers, but how can I change that?

I have removed the group layers and group sources, but the error still remains.

If anybody can help me out and pointing to a solution, it will be most welcome.
