dhtmlxConnector using Java with Spring FrameWork

Our registration number is 299592085.



I have been refering to this link dhtmlx.com/x/download/draft/ … r_java.zip for using dhtmlxConnector. But I am getting this error javax.servlet.servletexception:Error allocating a servlet instance.



How do I proceed for the above ?

What does the file with the extension .do refer to because I am not using any such file in my application.





Please send a reply at the earliest





Which version of JRE you are using?
Connectors support both 1.6 and 1.5 ( sample is compiled against 1.5 ) , but will not work for 1.4


We are using JRE 1.5.0_07



we are also attaching the screenshots the error we are getting.



Kindly guide me further.





The jar was compiled with JRE 1.5.0-b64 and must work with any later version of JRE
The error on your screenshoot appears when JRE used by the server has lesser version.
Technically you can rebuild the jar with your version of JRE ( jar contains all the sources inside )
