Hi pushkar,





Sorry for this - I expect my moving the post here did not trigger a mail to moderators and they missed this. I expect they will answer soon.





In the meantime I would gather the environmental variables and context - I expect this will be there first question

Hi,





You should include the appropriate JDBC driver in to your CLASSPATH system environment variable.

Hi Thanks for your reply, accordingly I have downloded crimson and mysql-connector-java-3.1.12-bin. Added them to system path





1) C:\Program Files\crimson-1.1.3\crimson.jar


2)C:\Program Files\mysql-connector-java-3.1.14\


mysql-connector-java-3.1.12-bin.jar





But still it is giving same error "java.lang.ClassNotfound exception"


Please suggest me what to do?


Thanks

Please note it's all about the CLASSPATH, not the PATH.

Quote:

C:\Program Files\crimson-1.1.3\crimson.jar

You do not need the crimson jar if you are using Java 1.4 or higher (recommended).





Also, it's easier of you do not use directories with spaces in their names.


I suggest creating e.g. a "C:\lib" directory to store jar files.

Please also make sure you have started a new command prompt after changing environment variables.





Are you launching JChemManager via an icon created by the installer ?


Please be aware that in some early versions of the installer (AFAIK JChem 3.2) the system CLASSPATH wasn't correctly passed on to jcman if it was launched with an icon. The later versions (where a command-prompt also opens in the background) work correctly.

Hi,


I think I am missing some thing so attaching


1) readme.txt file: All the steps I did for Java and Jchem installation


2)Images of error messages I got


Please see them, and do suggest me what to do

Hi,





A general tip:


You can copy-paste from a command-prompt window in Windows by activating the "Quick edit" mode.





Regarding the problem, your connection properties seem to be very strange:

Quote:

JDBC driver: Jdbcproperties URL of database:Jdbc Property table:Jdbcproperties

These values make no sense.


"Jdbcproperties" is not the name of a JDBC driver class, so it's not surprising you get the exception.





Please read the documentation and our FAQ on how to set these values:

Have yo tried Instant JChem yet ?


While JChem is more like a toolbox for administrators and developers, Instant JChem is an out-of-the-box product, which allows you to work within 5 minutes of launching the interactive installer:
