Python problem with wsdl2py

Dear support,

This is the setup: python2.4, ZIS2.1, Webservices 5.2.04
Using wsdl2py I could sucessfully generate the Python files for ChemicalTermsWS and StandardizerWS. I tested the example ChemTermsScript.py and it works fine.

However, when I use wsdl2py.py to convert the MolConvertWS service, I get this error message:

wsdl2py --complexType "http://xxx:xxx/axis2/services/MolConvertWS?wsdl"  
Traceback (most recent call last):
  File "xxx/python/bin/wsdl2py", line 7, in ?
    sys.exit(

Any help is appreciated, since the MolConvertWS service is what I am actually interested in.

Thanks and best regards,

Daniel

Daniel,

Thanks for your interest and questions regarding JChem Web Services.

 

The problem was related to the Java exception types, which have been replaced with the simple Exception type.  This new server change has been tested and is working here.

I have also created a new Python script to work with the MolConvert Web Service, attached below.

 

These changes are scheduled to be included in a hotfix release (5.2.4.1) next week.

Daniel,

To aid in your web services evaluation, I also uploaded a quick fix of our server code (~20MB)  to the website at:

http://www.chemaxon.com/shared/jlee/stoffler/JChemWebServices.aar

(This has since been removed, please download the latest version of JChemWebServices)

Place this .aar file in the following directory and restart the server:

<JChemWebServices5.2.4 directory>\tomcat\webapps\axis2\WEB-INF\services

 

We appreciate your questions and comments.

Jonathan Lee

 

 

 

The changes will be included in the 5.2.5 release and can be downloaded from the link in the previous post until the 5.2.5 release. 

At the present time, the proposed 5.2.4.1 hotfix release has been cancelled.

Hi,

I'm trying to use the MolConvert wsdl as well.  When I enter:

C:\Python26\Scripts\wsdl2py --complexType http://localhost:8180/axis2/services/MolConvertWS?wsdl

I get a similar error as Daniel, but I'm using a version of web services downloaded just this past Monday.  The error message is below.

Traceback (most recent call last):
  File "C:\Python26\Scripts\wsdl2py-script.py", line 8, in <module>
    load_entry_point('ZSI==2.1-a1', 'console_scripts', 'wsdl2py')()

Am I doing something wrong?

Thanks

Ben

Ben,

The new 5.2.5 version of JChem Web Services was recently released on September 18th and includes the fix for this problem.

The above issue was not working in the 5.2.4 version.  Please download the new version and try again.
