If we purchase a Server Edition do we need a seperate license for our development server and development workstations?

No, Server Editions are licensed per production server. You may use the same license on development workstations and development servers.

If we purchase a Developer Edition, do we need to license servers that we deploy to?

No, Developer Editions are licensed per developer. A developer can deploy an unlimited number of server or workstation based applications and assemblies royalty free.

How is the licensing information included in my redistributable application?

With a developer license, your unique license key is embedded in your application or added with one line of code when your application starts. This license key can be retrieved from our website after purchasing a Developer Edition license.

Our server has multiple processors. Do I need to purchase a license for each processor?

No, our Java products place no restrictions on the number of processors on the machine.

Do I need to purchase a maintenance plan to recieve upgrades or updates?

No, upgrades between minor version are free. Upgrades between major versions are provided free to maintenance subscribers and are offered at a significantly reduced cost to other licensed users.

Are there recurring costs when using your product?

No, once you purchase a license you can use that version of the software as long as you like. You can choose to purchase a support plan if you want preffered e-mail and telephone support and free upgrades between major versions.

Why do I see the PDF code in the browser instead of the PDF document?

This can be caused by using the refresh button after correcting an error. IE does not update the MIME type when using the refresh button. It is best to always link to the page from another to ensure that the MIME type is set correctly. This can also be caused by outputting HTML before the DrawToWeb method is called or by adding custom HTTP headers to the output stream.

I have already set the classpath to your Jar file. Still I am unable to run the examples. Why?

Verify whether classpath exists to the current working directory. If not add "." in your classpath.

Can I put the servlet examples inside a sub-directory within the default directory of the web server?

No, since servlet examples do not belong to any package.

Where I can store the DynamicLicenseServlet ?

You can store DynamicLicenseServlet at any location accessible within the web server after editing the source code and adding the appropriate package statement. Then modify the servlet mapping entries in your web.xml appropriately.
