Uploading assets to AEM Cloud Service is a 3 step process (initiateUpload.json, Upload to blob storage, completeUpload.json). Tools like https://github.com/adobe/aem-upload can be used to upload files to AEM using a NodeJS client... This post is on creating simple assets (text , json files etc.) in AEM using CURL or other third party apps in a single step (in traditional AEMs this is provided by .createasset.html check documentation). Pass the fileName and fileContent parameters to create assets in AEM with this servlet installed... Solution Add a servlet apps.experienceaem.assets.core.servlets.EAEMCreateAssetServlet to create the assets in AEM... package apps.experienceaem.assets.core.servlets; import org.apache.commons.lang3.StringUtils;
