I have successfully published three shapefiles as a layer group in GeoServer. However, in my web application, I am currently facing an issue where only one layer from the layer group is displaying, and I intend to display all the layers in the group.

Check Layer Visibility: Start by verifying that all the layers within the layer group are set to be visible. In GeoServer, each layer has its own visibility settings, and if any of the layers are set to be invisible, they won't be displayed in your web application. Layer Order: The order of layers within the layer group might affect their visibility in the web application. Ensure that the layers are ordered correctly within the group. Layers that are positioned lower in the list might be drawn on top of other layers, obscuring their visibility. Layer Group Properties: Check the properties of the layer group in GeoServer. Make sure that the bounding boxes and coordinate systems of all layers in the group are consistent. Mismatched bounding boxes or coordinate systems could result in some layers not displaying correctly. Layer Styling: Ensure that each layer in the group has a defined style. If a layer lacks a proper style, it might appear as if it's not displaying, even though it's there. Double-check that all layers have valid and appropriate styles assigned. Zoom Levels: Verify whether the layers are visible at the current zoom level in your web application. Some layers might be set to be visible only at certain zoom levels. Try zooming in and out to see if the visibility changes. Web Application Configuration: Examine the code or configuration of your web application. Ensure that you are correctly referencing and displaying all the layers within the layer group. It's possible that a coding error is preventing some layers from being displayed. Map Extent: Check if the extent of the map being displayed in your web application includes the geographic area covered by all the layers in the group. If the layers are located outside the current map extent, they won't be visible. Caching and Refresh: If you have caching enabled in either GeoServer or your web application, try clearing the cache and refreshing the map. Cached layers might not update immediately with new data. Log Files: Look into the logs of both GeoServer and your web application for any error messages or warnings related to layer display. These logs could provide insights into the root cause of the issue. Browser Console: Open the developer console in your web browser while accessing the web application. Look for any JavaScript errors or warnings that might be affecting the display of layers. GeoServer WMS Capabilities: Check the WMS capabilities document of your GeoServer to ensure that all layers and layer group information is being correctly exposed. This can help verify that the layers are correctly set up in GeoServer. Server Load and Performance: If your server is under heavy load or experiencing performance issues, it might impact the rendering and display of layers. Make sure your server has enough resources to handle the layer rendering.
Here are some steps to troubleshoot and address the issue:
By systematically going through these steps, you should be able to identify the cause of the issue and take appropriate actions to ensure that all layers within the layer group are displayed correctly in your web application.
