licensing

Are iText Java libraries to generate PDF documents free or do we have to pay for it? Bruno Lowagie I am the original developer of iText and the CEO of the iText Group . I'm also a Mentor at the Founder Institute . Please take a look at my slides for the session about Startup Legal and IP for the Founder Institute: http://www.slideshare.net/blowagie/startup-legal-and-ip iText is software and therefor copyright law applies: Copyright law allows an author to prohibit others from reproducing, adapting, or distributing copies of the author's work. According to the copyright law, you do not have the

I would like to add licensing system to application. For example: user buys license for 1 month and after that program expires (Kinda Anti-Virus style?). Problem is that application is supposed to run in systems which may or may not be connected to internet , so how to protect from date-time changes? Storing app startup and close times in encrypted file won't work as date can be changed (with program uptime of 8 hours per day, would be possible to extend license to almost 300% in ideal case - change time to app close time + 1 second before launching program). Another question - is there any

We are planning to develop a client server application using C# and MySQL. We plan to sell the product on the shelf like any other software utility. We are worried about the decompilation of our product which does have some sort of edge over our competitors in terms of usability and bundled functionality. How can we prevent our software from decompilation, so the business logic of the product remains intact? We have heard about Reflector and other decompilers which makes our code very much vulnerable for copying. Our customer base is not Corporates but medical practitioners who themselves may

I saw the stock Android-Developer licensing library instructions , but the overview seems to omit several key steps in the process and fails to fully explain how to get something working. Can someone provide an explicit set of operations that worked to get the licensing library set up on an Android app so it checks to ensure that a user has paid for an app in Google Play before allowing use? I have been working on implementing licensing in my app for some time now and finally have it working. I wanted to share some of the things I found helpful for getting started and some problems and

Can you recommend a Java decompiler for Eclipse? My other questions is what restrictions is there for using a decompiled code from an other Java program? Illegal or what? I dont know much about licenses. Thanks for reading. Mirek Pluta I'd suggest the one that pops up on google, which is the JD Java decompiler. It works really nice. As for the restrictions, you'd have to read a license of particular software, there might be written that any way of decompilation is forbidden. Thorbjørn Ravn Andersen I like JadClipse - but it shows its age in places. You will need: a jad binary jadClipse

As far as I know, when I build a desktop/server app using any GPL code like MySQL I will have to release the source code of my software under the GPL. If I want to develop a web-app using MySQL, my code will link against the MySQL libraries. Must I release the sourcecode of my webapp in this situation to be in accordance with the GPL? Provided that you keep it server-only(and therefore "private"), you don't have to release it as GPL. But as soon as it reaches public desktops, it can no longer be considered an internal build, and therefore source code is needed. So you can: Release your code as

The experiment I am currently working uses a software base with a complicated source history and no well defined license. It would be a considerable amount of work to rationalize things and release under a fixed license. It is also intended to run a a random unixish platform, and only some of the libc's we support have GNU getline, but right now the code expects it. Does anyone know of a re-implementation of the GNU getline semantics that is available under a less restrictive license? Edit:: I ask because Google didn't help, and I'd like to avoid writing one if possible (it might be a fun
