Troubleshooting with ImageIO plugin registry issue (NoClassDefFoundErrors) without web.xml file

[bms82]

Tag the question with javax-imageio and/or twelvemonkeys and we'll find them there.

I wanted to add that Spring Framework users who are not willing to use web.xml file, there is an alternative.
I added the following code for ServletInitializer class (which extends SpringBootServletInitializer).

import com.twelvemonkeys.servlet.image.IIOProviderContextListener;
@Override public void onStartup(ServletContext servletContext) throws ServletException { servletContext.addListener(IIOProviderContextListener.class); super.onStartup(servletContext); }

I hope this helps.

Hi @bms82 !

Thank you for the information. I believe this is the programmatically equivalent in Spring to adding the class to the web.xml. Do you think it should be added to the readme? If so, would you create a PR for that? Otherwise it might be better to ask a question on StackOverflow, as I'm not sure if people will find this issue once I have closed it.

Closing for now, as there is no action to be taken.
