License in Ubuntu/Windows

Hi,

We have deployed our application in JBoss Sever in Windows/Ubuntu system. In development environment the application works fine without any license installation. But when it is at client location it gives some license issues.

Implementation:

<center>

<script type="text/javascript">

var mrvData = document.getElementById("frmMarvinSketch:moleculeTxt").value;

msketch_name="MSketch";

msketch_begin("../marvin/",800,400);

msketch_param("mol",mrvData);

msketch_end();

</script>

 

</center> 

Question 1:

We require a sever level license installation. As per the documentation I have installed the license through environment variables:

Variable Name : CHEMAXON_LICENSE_URL

Value : D:\Marvin License\license.cxl

But when I open the Marvin Editor, the license path shows :

C:\Users\mohith.kumar\chemaxon\license.cxl

 

Question 2:

How can I install license if my server is running in Ubuntu.

 

Question 3:

Does any code change is required in the HTML file?

How will I verify if the Marvin Editor is using the license I have configured. Mainly in Development environment all the functionalities work without any license configuration.

Hi,

 

I assume that you are integrating Marvin as an applet into your application. In this case the Applet runs on the client machine so it uses the environment of the client.

Setting the environment variables works only for server-side code.

You can set the license for the Applet using the license or license file  parameter.

 

Best regards,

Peter

Yes, I agree.

Can you post a sample code, that sets the license on client side.

 

You can find a code example here.

Is your previous reply complete ?, I think you missed the link while posting

Yes, the link was left out.

Here it is: https://docs.chemaxon.com/display/marvinview/Licensing+Applets

I'm sorry  for the inconvenience.

Our application is depoyed in a ubuntu server, Through java I will initialize the mrvLicensePath  to the below value :

mrvLicensePath = "https://10.106.100.178/usr/local/jboss-as-7.1.1.Final/license/license.cxl";

 

HTML Code:

msketch_name="MSketch";

msketch_begin("../marvin/",800,400);

msketch_param("licenseFile",mrvLicensePath);

msketch_param("mol",mrvData);

msketch_end();

 

When applet is instantiated it shows the below message :

License is not found: https://10.106.100.178/usr/local/jboss-as-7.1.1.Final/license/license.cxl

 

Kindly help me in solving this issue.

I have solved this issue, we need to use http: instead of https:

Everything was working fine. Suddenly I am getting this issue now 'The license is not a well-formed xml:'. The license file is never modified.

Can you just help me in resolving this.

We throw this exception when the license file could not be validated.

 Could you pass the full exception? The cause of this should be mentioned there.

Many thing can cause this kind of error e.g. the file was not loaded completely due to network issues or the file was corrupted during the transfer.

Below is the Exception :

chemaxon.license.LicenseProcessingException: The license is not a well-formed xml: http://10.106.100.178/usr/local/jboss-as-7.1.1.Final/license/license.cxl

I thought it would be more useful...

Please send me a license report to pcseh _at_ chemaxon.com, that will contain log files and some licensing-related information as well.

Due to this issue ('license is not a well-formed xml') in the license, Marvin Editor don't even get instantiated. How am I going to get the 'Create Report' link ? It will not show the applet. Marvin Applet space will be empty since it couldn't validate the license.

I can send the license file if required.

 

Thanks,

MK

Can I please get any response regarding the above query ?

Sorry for the delay, we were thinking about how to get more information about the errors during applet loading.

Could you check out the java console during applet loading or check the lic.log files under your user home/chemaxon folder? They may reveal some more information about the problem.
