Image problems

[Migrated From Jforum.net]

Hi,

Anywhere where I use images (when registering anew user, setting a personal image) I get an exception.

What is wrong with it? I have taken a look around and I see that there were many problems associated with images. However, I am not sure what that is.

I think the problem is access to graphic libraries.

If you are using Tomcat try adding -Djava.awt.headless=true on your catalina options.

Without this options on unix, graphics libraries are not available if your computer has X installed (or running I don't remember)

And Linux systems need at least the X11 base libraries loaded ...

Hi,

I have Feodra Core 5 installed.

I'll add -Djava.awt... in my catalina options and see how that works.

How do I load X11 libraries? I am not sure what those are.

Thank you.

Thank you.

X11 is a graphical "windowing" application/library for Linux systems. Do a Google search for X11 and Fedora .... you will find links to RPMs to install for your version of Fedora. Or, if you are familiar with using the RPM installer to search for packages to install, search for X11 Base Library.

Since you are running it on a server, you don't need the entire X11 system/setup, but you do need the base libraries to handle and process images.

Thanks.
I'll try that out and see how that works.
