Hi vladimir, May I know the GroupDocs.Viewer-for-Java only provide server site integration/API? and Do our development team needs to build the viewer in web page? and i downloaded the sample from URL https://github.com/groupdocs-viewer/GroupDocs.Viewer-for-Java. and Found the sample only output html file. May i know how can we start in the programming integration level? We hope to build the web app like ‘https://products.groupdocs.app/viewer/app?lang=en&file=8bdf945f-b162-42a9-9275-ace1c70942c8/00020IDENT2023.tiff


To get started you can use one of our demo projects. You can configure which mode (html or image) you want to work with. Let’s take Dropwizard Demo where you can set htmlMode: false to run the app in image mode. The condition if (viewerConfiguration.isHtmlMode()) is used to instantiate corresponding services.

In case you would have any other questions about GroupDocs.Viewer for Java please create a new forum thread at https://forum.groupdocs.com/c/viewer/9.
