You may have several incompatible jar files on your Tomcat "classpath". (For example you may have mistakenly copied jcart.jar along with jchem.jar. Both contain the chemaxon.util.StringTools class, but jchem.jar is signed whereas jcart.jar is unsigned.)





Please, could you post a listing of the <tomcat-home>/shared/lib directory?





Also, how did you deployed jchemstreams.war. Did you drop it into the <tomcat-home>/webapps directory?

Thanks.





I removed jcart.jar and reloaded. It's working now. Thanks.
