Hello,

I am new to ChemAxon, have just installed it with tomcat 6.  However when I go to:

http://<URL>/webservices/, I get:

 

HTTP Status 500 - !(Jetty || Servlet 3.0 || ContinuationFilter)

---

type Exception report

message !(Jetty || Servlet 3.0 || ContinuationFilter)

description The server encountered an internal error that prevented it from fulfilling this request.

exception

java.lang.IllegalStateException: !(Jetty || Servlet 3.0 || ContinuationFilter)

	org.eclipse.jetty.continuation.ContinuationSupport.getContinuation(ContinuationSupport.java:150)

	org.eclipse.jetty.servlets.GzipFilter.doFilter(GzipFilter.java:248)

 

note The full stack trace of the root cause is available in the Apache Tomcat/6.0.39 logs.

---

Apache Tomcat/6.0.39

Any idea what to do?

Thanks,

Maged 

Hi Maged,

Tomcat 6 is not supported by JChem Web Services, please use Tomcat 7 or later.

We are running JChem Web Services 14.10.13 on Tomcat 6. When was the Tomcat 7 requirement introduced?

Also, is there a History of Changes page specifically for JChem Web Services? I found a link to a history of changes of JChem Web Services in the sticky thread in the forum for JChem Web Services, but it brings me to the history of changes of JChem Base. 

Hi,

This requirement is since the beginning, I suggested you a workaround here:
https://www.chemaxon.com/forum/viewpost53207.html#53207 />
This solution still should work, please try it!

There is no separate history of changes for JChem Web Services, it is always built on top of the JChem library, all cahnges are reflected on the api.

This is what I did previously and I am still getting the same error!!

I have the following versions:

Server version: Apache Tomcat/6.0.39

Server built:   Feb 24 2014 06:09:30

Server number:  6.0.39.0

OS Name:        Linux

OS Version:     3.13.0-63-generic

Architecture:   i386

JVM Version:    1.8.0_60-b27

JVM Vendor:     Oracle Corporation

 

On Ubuntu 14

And jchemWebservices15.9.14.0-b621

 

Thanks,

Maged

Hi Maged,

Are you sure you have disabled the GzipFilter? You cannot have it in the stacktrace if it is disabled.

java.lang.IllegalStateException: !(Jetty || Servlet 3.0 || ContinuationFilter)

	org.eclipse.jetty.continuation.ContinuationSupport.getContinuation(ContinuationSupport.java:150)

	org.eclipse.jetty.servlets.GzipFilter.doFilter(GzipFilter.java:248)

Or are you getting some other error now?

Regards,

Hi Peter,

 

It was my mistake, I guess the webservices.war file did not update.  I have now corrected the problem and all looking good.

Thanks,

Maged

How to install jchem webservices for jboss6?

In webservices.js,Do we need to specify servername which is till root folder or till the folder where webservices.war is installed?

Hi,

Jboss is not supported by JChem Web Services. Please install it in a supported application server like Tomcat or Jetty!

Regards,
Peter
