Problem with generate_image.jsp

Hi,





I seem to be having a weird problem with generate_image.jsp that one of the guys set up. Using the following url:





http://myserver/marvin/generate_image2.jsp?mol=Clc1ccc2cc(Cl)ccc2c1&format=png%3Aw170%2Ch110%2Cb32%2C%23ffffff





No image is returned, if i put some debug statements in it appears that an error is thrown when the following is called:





mol = MolImporter.importMol(molstring);





And the error is at chemaxon.marvin.util.MolLoader.splitFormatAndOptions





This seems very odd as i wouldn't imagine splitFormatAndOptions to be called during importMol, and not called until mol.toBinFormat(format) in generate_image.jsp





Have you come across this before ?? I believe it's using Marvin Beans 4.1.2





Cheers


Alistair

I still haven't figures this one out, i suspect i've got some version problem maybe, i've tried some older versions of Marvin (3.1.1) but still no joy. The full stack trace is:

It may be a CLASSPATH problem in your server.


There is not any MolLoader.splitFormatAndOptions() method in current Marvin.


In ancient Marvin versions (till Marvin 4.0.5), it existed. But this method has been moved into an other class.


Please check if there are more MarvinBeans.jar or jchem.jar in the CLASSPATH of your Tomcat. If yes, please remove the old versions. Since jchem.jar includes also the Marvin Beans API, CLASSPATH can not include both of them (to avoid mixing different versions).

Thanks for the info


I fixed this last week, and the problem was that there was a jar in the classpath but also a jar included within the application. So I removed the jar from the classpath and specified during deployment to the server that the application should use local resources first. That removed the problem.
