Hi everyone, First thank you for your consideration.
Well, I am a newbie to CDK and I am trying to use it, from Ruby through the Ruby Java Bridge (Rjb). I have installed CDK (1.3.1) according to the README file (using ant etc..) and copied all the created jar files into a lib/cdk subdirectory in my project's main dir. Using the right syntax, I have been able to import some external (non cdk) classes. However, when applying it to CDK it seems that something is not quite right. I have tried to import different classes such as the EStateFingerprint class from org/openscience/cdk/fingerprint (after I added the absolute path (/home/******/lib/cdk/cdk-fingerprint.jar to fingerprint.jar to my CLASSPATH and made sure that it is included). The line in my code is: fp=Rjb::import 'org.openscience.cdk.fingerprint.EStateFingerprinter' I got the following error: in `import': org/openscience/cdk/fingerprint/IFingerprinter (NoClassDefFoundError) This class is required in EStateFingerprinter.java and is present in the same fingerprint.jar too (as EStateFingerprinter). So, I do not understand the (NoClassDefFoundError). I tried to import another class: SMARTSQueryTool from (org.openscience.cdk.smiles.smarts.SMARTSQueryTool) and add a similar error. This time, the class org.openscience.cdk.interfaces.IAtomContainer was not found, although it is included in the "interfaces" subdirectory. I have to mention that I also added the correct path to the class in my $CLASSPATH and logged off/on (eventhogh a source /etc/profile might have help at least for the current session). I could not find a thread related to this issue, so I am stuck here. Could someone help me out, please? Yannick
