Deleted my account at Bintray

I deleted my account at Bintray because I can not use this repository. It is too confusing to me. It does not mean any kind of lost of interest. Because of what happend to TrueCrypt I think it is better to point this :-)

I was originally signing in because I want to provide the libraries via Apache Maven repository. Im now heading to use Maven Central.

By the way: This is not TrueCrypt. This software comes with a licence which is short, clearly and wide spread. The TrueCrypt team did a great job for many years but why do they do leave us with such a monster of a licence?... read more

Problem with JDecisiontable for .NET discovered

I discovered a bothersome problem with JDecisiontable for .NET:
Shortcuts like Ctrl-Alt-R, Ctrl-Alt-I etc doesn't work. Please use the menu items. With Java these shortcuts work (both, .NEt and Java version tested with Windows(R)). I don't know if this is my fault or if it is a problem with IKVM.

I still released a .NET version for JDecisiontable_2.3.0-BETA1. Undo/redo seems to work here too.

Added an important document to Help zip files

I just added an important document to Help zip files.

It is named How_To_Make_Decisiontables and describes the technique of process-oriented decision tables for which JDecisiontable is the software.

For good reasons, the development of this document is tracked in the project JDecisiontableLib in the folder Help.

Release of JDecisiontable_2.3.0-BETA1

(There was a post before but accidently I deleted it)

I released JDecisiontable_2.3.0-BETA1 so you may try out the undo/redo feature I added since JDecisiontable_2.2.0.

There is a branch version_2.3.0_BETA1 from which these binaries are build.

Currently, the menu items for undo and redo are disabled when no decision table is open but not when there no action to undo or redo is available. But I took care that nothing happens if you hit undo or redo in the situation. Just the menu items are not disabled yet.... read more

Added undo/redo for JDecisiontable 2.3.0

I added undo/redo for JDecisiontable 2.3.0. It seems to work but it needs of course proper testing.

I merged the branch version_2.3.0_addUndo into the branch master to complete the next release. Please be patient.

Command pattern successful applied

The command pattern was successful applied in branch version_2.3.0_applyCmdPattern. All Tests are OK again. So I merged the branch version_2.3.0_applyCmdPattern into branch master.

Now I am working on branch version_2.3.0_addUndo to implement the undo/redo feature. You should find a new menu for this purpose.

Edit: I decided to add the menu items "Undo" and "Redo" below "Tools".

Preparing JDecisiontable 2.3.0

Recently I started to prepare JDecisiontable 2.3.0. This release is intend to introduce the ability to undo/redo actions. I.e. if you remove a rule you can undo this action - this restores the removed rule.

I do this by implementing the command pattern. This means we will not sotre the whole decision table after each action but to store each command. Each command does not only know how to change the decision table it also knows how to revert this change. So we need only very little bit additional memory for undo/redo.... read more

Released JDecisiontable 2.2.0, updating JDecisiontable 2.1.0

Hi,
I just released JDecisiontable 2.2.0. Beside some cleaner code in the sources the noticeable change is that you can copy-and-paste decision tables and test specifications to the clipboard. This feature was added because the Decision Table Creator - also hosted on sourceforge - has it too.

You may mark any range of cells of a decision table and the press Ctrl + c. This will copy the content of the marked cell to the clipboard. If you want to copy the whole decision table to the clipboard you need either to use the menu or to click on the label on top of the tab first and then press Ctrl + c.... read more

Uploaded new files because I forget the icons

I uploaded new files because I forget to include the icons so that users can apply an icon to the launcher.

JDecisiontable 2.2.0

Currently I do JDecisiontable 2.2.0. There will be three new menu items which enable you to copy decison tables or test specifications to the clipboard.

Release of JDecisiontable for Microsoft® .NET® 2.1.0

So, here it is: JDecisiontable for Microsoft® .NET® 2.1.0. I used a newer version of IKVM compared with JDecisiontable for Microsoft® .NET® 2.0.1 (7.4. release candidate 0), now it looks and feels better.

Furthermore I updated the documentation (README, LIESMICH, THIRD_PARTY_LICENSES because of IKVM).

Release of JDecisiontable 2.1.0

Today I can release JDecisiontable 2.1.0.

There are not so much changes here. At first you may recognize that there is an additional column in the left hand table. Now each node has a number as each rule as a number. This number doesn't appear in the reports. If you open a CSV file in a spreadsheet application there is a line number for this purpose.

Another remarkable change is that CSV files are no longer encoded as UTF-8. Now they are encoded as UTF-16LE with Byte Order Mark. In brief, this change makes it a lot easier to open CSV files using Microsoft(R) Excel(R). Trying with different encodings and Microsoft(R) Excel(R) 2010 proved that this encoding caused Microsoft(R) Excel(R) to open such a file just by a double click! Libre Office also opened it but asks for the ecoding - "Unicode" is the right answer.... read more

Work in progress

Hello
Maybe you watch the commits I made but dont know about the goal behind them?

JDecisiontable 2.1.0 is code- and feature completed so far. All existing automatic tests were green. I am working on the underlying library JDecisiontableLib which temporary breaks JDecisiontable so the automatic tests will be red for few days. These changes were triggered by examining my source code with PMD and FindBugs. You will find more details in the JDecisiontableLib project blog.... read more

Merry Christmas - developing goes on!

If you got some questions or need help you may email me. I can take a week until I answer but I will do.

And - a user emailed me. I could help him quickly. Now I knew someone out there uses JDecisiontable. I'm happy.

Moreover, this user uses the NET-version I did with IKVM! Without this users feedback I would have discontinued to provide NET-versions but so I will continue to provide them.

After having a release of Bifurcum/Bifurcumlib 1.0x/2.0.x I will care about JDecisiontable again. It would be nice to remember the files I used recently.... read more

Development will continue

Actually i'm busy with earning money as software-tester but development will go on.
I'm very interested in it because I want to get hired as developer. To have fresh open-source projects is meant to compensate that I'm an engineer but never studied informatics (and hired as software-tester, too).

There are some minor features like open recent files or copy the content of a decisiontable to clipboard left. I now have Emma to measure code coverage (after Cobertura quitted working right before JDecisiontable 2.0.1) and Findbugs to find possible bugs. I will apply both later.... read more

MIT licence

I decided to apply the MIT licence after reading this helpful article: Closing the Loophole: Open Source Licensing & the Implied Patent License written by Christian H. Nadan.

I still don't hold any patent and have no patent pending. So the shift away from Apache License is not to trick you but to make life a lot easier again *).... read more

JDecisiontable 2.0.1 released

Main reason for this release is to fix the errors in version 2.0.0. List of changes (from README.txt):

1) Solved the problem with german umlauts and other non-ASCII chars in the version for Microsoft® .NET®. The solution was to change the class de.mgmechanics.myflipflops.File.TextResource. Now it is possible to read all resource files either from outside the jar or exe file XOR from inside. Which one will be used - those from inside or outside jar/exe? While launching JDecisiontable looks for a file StringResource.json in the same folder as the jar/exe is. If found it used it as default resource file and tries to read all other resource files from same place. If they are not there they are considered to be not available.... read more

JDecisiontable 2.0.0 removed from download

JDecisiontable 2.0.0 was removed from download because JDecisiontable for Microsoft® .NET® wasn't working as expected. The bugs are fixed in sourcecode (HEAD of master branch) but I need some time (maybe a few days) to test it carefully.

JDecisiontable 2.0.0 released

Now JDecisiontable 2.0.0 is rolled out. Main new feature is internationalisation. First local version available is German. Furthermore there are some minor improvements and even a bugfix.

Today (2013-02-14) I uploaded a new zip file containig improved StringResource files (now with Windows linefeeds) and a German localisation for .NET without umlauts.

I am still looking for a solution how to run JDecisiontable under Windows without Java installed. I said I wouldn't release a version which contains a jre - but maybe I do. IKVM works great but does not provide same user experience as pure Java.... read more

How to cause sourceforge.net to offer the most recent file to download

If you upload two files with different version number within one day(?) the green button shows the older version i.e. yesterday I uploaded
- JDecisiontable_version_1.1.2.zip
- JDecisiontable_version_1.1.3.zip

And it offered JDecisiontable_version_1.1.2.zip in the green button. Today I uploaded same file - JDecisiontable_version_1.1.3.zip - again. Now this file appears in the green button.

Furthermore I observed that any executable over an zip file. I.e. after uploading both files yesterday the file JDecisiontable_1.0.2.jar disappeared after removing it fron Files area. I replaced it by a zip file containing this file and belonging help files.

  • JDecisiontable 1.1.2 (also to run with .NET)

  • JDecisiontable 1.1.3 (to run with Java)

  • JDecisiontable 1.1.2 (to run with Java)

You need to go to **Files" to get the zip for version 1.1.3 - sourceforge.net offers version 1.1.2 in the green button. What the >piep< is the algorithm therefore?!... read more

I'm on the way...

Yesterday I bought Windows 7 Home Edition to try out IKVM. I'm installing it at Virtual Box virtual machines using my Linux machine. The Windows XP SP3 installations used before seems not very safe to me any longer.

There is also an article in the recent issue of Java Spektrum magazine about it. If you find out - mail me!

I also have to finish another project first before I can go on with this. But I care ...... read more

How Oracle ruins my business and how I try to rescue it

How Oracle ruins my business :-(

I appreciate very much that Oracle brings free Java to me at very high expenses. In this spirit and to give back just a very tiny humbe little bit to the Open Source community I spend hours and hours of my personal spare time to publish this humble little bit of source code you will find here.

It's a pain to see how it is ruined:

"Dangerous vulnerability in latest Java version" by The H
"Fix for critical Java hole released" by The H, reporting a second vulnerability
"Oracle's January patches close 86 holes" by The H, about other "nice" vulnerabilities open until Januar 15 2013... read more
