java security exception about signer information.

Hi,


I am using the jchem jar in my web application (using spring framework and hibernate for persistence) for calculating the logp, pka, exactmass etc. from a smiles string and I am getting the following exception:





java.lang.SecurityException: class "chemaxon.marvin.modules.DearomatizePlus"'s signer information does not match signer information of other classes in the same package





Please help!





Thanks,


Anu

I have moved this topic to the appropriate forum.





You can find some information about your problem in this topic: http://www.chemaxon.com/forum/viewpost7553.html





BTW please specify your Marvin version.

The error message indicates that some jars are signed and other ones are not in your CLASSPATH.


The jar files in old JChem/Marvin Beans releases were signed. But the newer ones are not.


The jars of Marvin Applets package are signed.


Probably there are jar files from different JChem/Marvin versions/packages in your CLASSPATH that can cause the problem.


Please check your CLASSPATH. Only one JChem or one Marvin Beans package should be in the CLASSPATH.


If the CLASSPATH is correct, I can imagine that you use an old buggy JChem version.


As I remember, long time ago, there was a JChem release where jar files were not signed consistently. Probably, you uses this version.


If you use the latest release, signing issue can not be present.


Are there any non-Marvin/JChem jar in the CLASSPATH? Probably you called the logP API from your own class that is located in a signed jar.
