Thanks for your inquiry. Aspose.Words for Java is just a class library and with it you can programmatically generate, modify, convert, render and print documents without utilizing Microsoft Word®. So, it does not offer any UI or web control for performing these document processing tasks on web pages.
Our sister company GroupDocs.com offers a viewer app which you may consider including in your application to view the various file formats. With GroupDocs apps, you can also have limited editing functionalities. For more information, I suggest you please contact GroupDocs support through live chat or support forums of GroupDocs.
Please let me know if I can be of any further assistance.
