JChemStreams not available

Hi





We have upgraded servers and I am trying to install our test JChem database system on the new server. I have followed the same instructions as last time (which was successful) but now I have encountered an error. If I attempt to navigate to http://localhost:8088/jchemstreams I get a 404 Tomcat error saying "The requested resource (/jchemstreams/) is not available."





However, if I navigate to http://localhost:8088 then I see the Tomcat homepage working OK. Please might you have any idea as to what I should check to get JChemStreams to work properly? I have saved the jchemstreams.war file to my Tomcat webapps folder.





Many thanks...

Hi,





The browser which you are trying to point to http://localhost:8088/jchemstreams is running on the same host where Tomcat is running, correct?





If the browser is running on a different host, the host name "localhost" must be replaced by the name of the Tomcat host.





Thanks

Hi Peter





Yes, it's on the same host. Tomcat is working because http://localhost:8088 loads up the Tomcat home page.





I have copied the jchemstreams.war file to the Tomcat\webapps folder but I cannot get the JChemStreams page to load successfully.

I suggest doing the following:





1. Stop Tomcat;


2. Remove the jchemstreams directory in the webapps directory, if present (don't remove the jchemstreams.war file);


3. Remove all content from the <tomcat-home>/work directory;


4. Start Tomcat;


5. After a few seconds, check if your browser can find now the jchemstreams webapp.





Let me know if this helps.

Hi Peter





Thanks for getting back to me. I tried your suggestion and it JChemStreams still did not work. Then I copied the entire Tomcat folder from the original server into the new server. Now it works - not sure quite why it didn't work with the fresh install but fingers crossed things seem fine now.





many thanks...

Unfortunately I have run into another error. When running the install.bat script as below:





install.bat jchem/password@dbname http://localhost:8088/jchemstreams/





I get an error message part way through the script (although it finishes with a 'Sucessfully Completed' message):

Code:

Connected to: Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - Production With the Partitioning, OLAP and Data Mining options PL/SQL procedure successfully completed. Call completed.

Afterwards when I attempt to run the test.bat script I get the error:

Tomcat is running successfully on the same machine as the database. I can connect to the jchem user from SQL*Plus without any problems and the dbms_java.grant_permission proc appeared to work OK. Any ideas would be greatly received... many thanks...

Which JChem Cartridge version are you trying to install?

I downloaded using the jchem-5_0_02-windows.exe link on your website.

Please, read the installation instructions. The installation procedure has changed starting with JChem Cartridge 5.0. Tomcat has been replaced by a command-line-startable application, and there is no jchemstreams.war at all.





Thanks


Peter
