Plugin tutorial page out


Hi guys,

I am building a plugin for Astah and I was using the tutorial available in However, this link is going to a 404 Error page now. Is it just some random error or the plugin development support is being discontinued? Hope the latter not to be true.

Thank you.

.jar not loaded in classpath


I am developing a plugin for astah that uses the FDR3 library (fdr.jar). I have added the following dependency to pom.xml:

FDR3 fdr3 1.0 system ${fdr.install}/fdr.jar

where ${fdr.install} is the folder where the .jar is located. I am able to build the project successfully (astah-build). When I start astah (astah-launch) it loads the extended view I created, however, when the code reaches any class of fdr.jar the console prints a java.lang.NoClassDefFoundError: uk/ac/ox/cs/fdr/fdr with the following trace:

I have no idea why a ClassNotFoundException is being thrown if the project is built successfully, that is, I am assuming that the jar was added to the classpath as expected. Could you help me pointing out what could be wrong here? Is there any way of viewing the complete trace?

I get the feeling that this issue has something to do with several .dylib files that this library requires in order to run properly. I have copied these files to /src/main/resources folder but still no success. Can I use the fdr.jar from the FDR installation folder without bundling it to the plugin?
