No doubt somthing small I have missed but it has been a while...any idea why this might occur on jchem server start?





Daniel.

Please, could you list the content of your C:\Program Files\ChemAxon\JChem\lib directory (with dir) and post the result?





Thanks


Peter

Thanks peter.

Is the commons-logging-1.1.jar file readable by the user running JChem Server?





Which JChem version is it?





Thanks


Peter

version is 5.1.0 and it should be readable by the user running the jchem server - i will check this...

seems to be readable OK but problem persists - anything extra required in CLASSPATH or PATH for jchemserver?

Try setting the JCART_XCLASSPATH variable:

Code:

SET JCART_XCLASSPATH=C:\Program Files\ChemAxon\JChem\lib\commons-logging-1.1.jar

Thanks


Peter

Hi Peter,





I have added the JCART_XCLASSPATH env variable and this seems to have had no effect...same error message prevails...even after machine reboot / new command prompt window...





Daniel.

Daniel,





What kind of Windows is it? Windows Vista? (I have tested this right now with Windows Server 2003.)





If you download a recent JChem version, does it exhibit the same problem? (You don't have to upgrade your JChem Cartridge installation, just unpack the zip and try starting server.bat.)





Thanks


Peter

Hi Peter,





I have downloaded and tried the latest version of jchem and get exactly the same error message as above...i am going to check path and classpath carefully now it must be them?





Daniel.

Daniel,





Try unsetting the CLASSPATH variable altogether (set it to empty):

Code:

set CLASSPATH=

Also, try another Java version (although I am very skeptical that the Java version would be a problem). I've just tested this with the most recent Java (Java SE Development Kit 6u11) with which it works.





Thanks


Peter

java -version:





java version "1.6.0_05"


Java(TM) SE Runtime Environment (build 1.6.0_05-b13)


Java HotSpot(TM) Client VM (build 10.0-b19, mixed mode, sharing)





I tried your suggestion above and alas again the error is the same...


It is windows XP and I am sure I had it working on here at some point...





Daniel.

commons-logging-1.1.jar is available to read from env var it seems but same error persists...

Daniel,

Quote:

Starting with JChem 5.1.1 org/apache/commons/logging/LogFactory is no more used in the code which threw the exception for your 5.1.0 installation. To be honest, I find it very hard to believe that you get the same error message with 5.1.3.2 as with 5.1.0.





Thanks


Peter

OK - perhaps I did not modify my JCHEMHOME when I tried it - let me do so and try again...

OK - I have made sure JCHEMHOME is correct and am using 5.1.3 server.bat file (does this need edit?) and it still does give the same error message?...I will continue to see if I can isolate why...





Thanks for your help.


Daniel.
