version change problem

I am just swapping JChem test release back to 3.1.6 and have changed all the usual files, jchem.jar jchemstreams.war ...etc...





The chemstreams seems to be in place and the jchem.jar file is the correct one for 3.1.6 however I get an error message relating to previous version - where can this be coming from?





JchemStreams check:


JChem version: 3.1.6


JChem Streams version: 3.1.6





SELECT Jchem_Core_Pkg.getenvironment() FROM dual :

Please help if possible.


Daniel.

Dear Daniel,





Please restart Tomcat after changing the jar file.


It's also worth to clear Tomcat's cache by deleting everything under


<your_tomcat_directory>/work





Please also change back the JSP pages, because the new JSPs are not compatible with the old version.





Let me know if this helps.





Best regards,





Szilard

Hi Szilard,





Perfect, clearing the work directory has solved the problem...


Thanks mate!





Daniel.
