Error: JChem repository not found

Dear Support,





I've downloaded:





(1) jchem_5_0_0beta2.zip


(2) marvin-applet-solubilityplugin-5_0_0beta2.zip


(3) marvinbeans-5_0_0beta2.zip





and extracted to a Tomcat server's 'WEB-INF/lib' directory the following:





- every .jar from (1)


- 'solubility4applet.jar' from (2)


- 'MarvinBeans.jar' from (3)





Using the following code:





----


try { PROBLEM


} catch (Throwable e) {


e.printStackTrace();


try


outs.println(HTMLTools.exceptionToString(e));


catch(Throwable nf)


outs.println("Error: JChem repository not found");


}


---


drops: 'Error: JChem repository not found'.





With JChem 3.2.6 everything is fine, it prints the exception.





Any suggestion to solve the problem?








Thanx!

First of all, 5.0.0beta2 was a pre-release of 5.0.0. It was only a test version. Beta2 still includes some bugs that are already fixed in the final 5.0 release.


So I recommend you to use the final release.


I have realized that download page still mentioned this beta as early access of next major release. It was misleading because currently, there is not any pre-release from the next major (5.1) version. I have removed these files from the dodwnload area to avoid further misunderstandings.





Furthermore, the solubility plugin is not released yet, officially. The solubility packages in the 5.0 release are only demos.


My colleague, Zsolt, can tell you more about the state of this project and help you if you would like to evaluate it.

About your Tomcat configuration:


You have placed too many jars into the Tomcat's shared/lib directory.


If you use JChem, you do not need the Marvin Beans package.


JChem jars include all that is required by Marvin (API or applications).


Copy only those jars into the shared/lib directory that you find in the jchem/lib directory. Please remove the MarvinBeans.jar and solubility4applet.jar from this directory. (Actually, solubility4applet.jar is built for the Marvin applets, not for the JChem API. If you really need solubility we can explain you howto configure it.)


Probably, the redundancy of jars caused the problem.


Is it solved the issue?


Next time, please post JChem configuration problem to the JChem forum.

Upgrading and removing 'MarvinBeans.jar' solved the 'JChem repository' problem, thanks.


However, I need solubility. With 5.0.0 beta2, including 'solubility4applet.jar' solved the problem, but after upgrading to 5.0.0 including any of the solubility .jars gives:





--


class "chemaxon.calculations.logP"'s signer information does not match signer information of other classes in the same package

Which one is that? I've found only 'Instant JChem'.

We will contact you in email regarding this issue.
