Hi Prashant,

Thanks for showing you interest in GroupDocs.Viewer for Java and letting us know about your preferred framework.

Our current showcase project is developed in Spring framework, but we have added your preferred framework in our support development plan.

As we get any update on it, we will inform you.

Best Regards

Hi Atir,

Thanks for the consideration !

But we are in urgency in this subject, I am planning to buy some licenses for the Group Doc viewer, But I was not sure that it will work in out current framework setup.

I have tried converting the servlets of JAVA sample application, but I am facing lots of errors in that.

We are using Struts2 Framework along with Hibernate to load file stream.

Its my humble request, if you guys can provide us guidance to set it up so that I can showcase the same to management.

Hi Parshant,

Thanks for explaining your concerns.

As you told:

I have tried converting the servlets of JAVA sample application, but I am facing lots of errors in that.

Can you explain that what kind of error you have found?

We are using Struts2 Framework along with Hibernate to load file stream.

Please let us know that did you try simple file loading in your application (Just like as done in our sample application)?

We’ll try our best to help you to resolve your issues.

Have a nice day!

Hi,

Yes, I when I am running the sample application for Java Servlet as it is, It is working fine.

But When I am converting the same servlets to Struts2 Action Classes, I am getting 404 error for loaded resources (CSS,JS,Images) and for all the Handler Servlets.

Prashant.Sharma · July 4, 2016, 12:35pm

Hi Experts,

I have got a Sample Application for Spring, Can you guys help us to give me sequence of these methods mentioned in controller class as attached in file.

Thanks

Prashant

Hi Prashant,

Thanks for giving a try to our Spring showcase example.

The concerned team is creating the documentation for the controller class you asked for. Once they complete it, they will update you in this thread soon.

Please stay tuned.

Prashant.Sharma · July 6, 2016, 5:47am

Thanks.

Prashant

muhammad.sabir · July 6, 2016, 9:11am

Hi Prashant,

Thanks for your feedback.

It is good to know that you are trying to implement at your end by learning from Spring showcase. At our side, we have added Struts2 showcase in our future plans. However, based on the pending tasks we have on our side, we may not be able to start working over it during the next few weeks. Once we make any progress over Struts2 showcase, we’ll let you know. In the meantime, if you come across any issues while implementing at your side, please do let us know. We’ll try to help you out as best as we can.

Best Regards

Prashant.Sharma · July 6, 2016, 11:57am

Hi Thanks !

can you please confirm my understanding for the document viewer controller methods calling flow ?

muhammad.sabir · July 7, 2016, 2:32am

Hi Prashant,

Yes, I think you are correct. For a detailed review of the diagram you created, I have asked the concerned technical team member to look at the flow for verification.

In the meanwhile, we have also released first version of the documentation of Spring MVC Front End which will give you more insight. Please feel free to have a look at:

http://www.groupdocs.com/docs/display/viewerjava/GroupDocs.Viewer+for+Java±+Spring+MVC+Front+End

Especially the below two articles sound useful:

http://www.groupdocs.com/docs/display/viewerjava/Technical+Overview

http://www.groupdocs.com/docs/display/viewerjava/GroupDocs.Viewer+for+Java+Front+End+JavaScript+API+Parameters

Hope it helps.

Best Regards

muhammad.sabir · July 7, 2016, 5:57am

Hi Prashant,

Thank you for coming back.

Apparently, the error stack indicates that the issue is with some particular document. I am attaching a couple of sample docs with this post and you can test them with the GroupDocs.Viewer. In case you are able to view these documents seamlessly, please share the particular document with which you are getting the said exception. In case the same error occurs with the attached sample docs, please do let us know.

Regards

Prashant.Sharma · July 7, 2016, 6:05am

Hi Sabir,

First of all Eid Mubarak to you.

As you have shared the methods called on different controllers, same way can you share the Request and Response Parameters for all the methods ?

Thanks

Prashant
