Academic research license is not valid for web usage?

Dear Sir:

I have recently applied and got a license file from this location:

https://www.chemaxon.com/forum/ftopic3670.html

But after a test, I found that the license can not be used on a web application. We tried to register the license via your API:

LicenseManager.setLicenseFile("E:\\Downloads\\license.cxl");

However, the license error is still there.

After we install the license via License Manager (which means a license.cxl file is copied to the user directory), then the application goes smoonthly.

On the other hand, a junit test shows no error, no matter we installed or removed the license from user directory (but still register via API)

After looking at the documents, we found there's another type of "academic web license", is this what we are looking for?

Can you change my license to that type?

Thanks a lot

Dear Urs,

You're right, to build a database you need an academic web license.

I've sent the license to you via e-mail. If you've got troubles with that license too please post your questions here.

Janos

Hi Janos:

Thanks for the reply, we got the new license file.

However, it does not work properly. This is what we did:

1. Pack the license file within our jar file


2. Load the license file content via classloader (no error, content can be seen via debug)


3. Call "LicenseManager.setLicense(jchemLicenseContent)" in servlet listener (note: not file path, but file content)


4. Call JChemSearch related function

Note: we did NOT install via the license manager.

Here is the error message:

No license file found.

One more thing, the junit used to work with the research license even if it is not installed via license manager, but with the web license, exception is thrown.

Anything wrong with our usage? I guess in a web environment we don't have a JChem environment, hence installation to user directory is not necessary, is this correct?

FYI: JChem 5.3.3, we use it for Marvin applet (input) & substructure search

this is the stacktrace we caught after set license file path: LicenseManager.setLicenseFile("E:\\Downloads\\license_web.cxl");

I uploaded some screenshot to my personal website since no attachment upload can be found here:

The strange thing is that both academic research and web license is valid for "web services server", don't know if this refers to a web environment.

Moreover, there is always a restriction: Server Use: Not Allowed

What does this "Server Use" stand for?

Hello, any idea?

Sorry for the delay, the main person responsible for this is out today - we can respond only on Monday. Alex

Hi,

Sorry for the delay, I'm investigating the problem.

The strange thing is that both academic 
research and web license is valid for "web services server", don't know 
if this refers to a web environment. 

Web Services Server is a different product, it is not relevant with JChem Base web access.

Moreover, there is always a restriction: Server Use: Not Allowed
What does this "Server Use" stand for?

'Server use=allowed' restriction means, that you can put the license file to a different machine (e.g. server) and  you can specify the path of license file remotely. As I see you specified this with local path, your license should work in this way.

Back to your problem, it seems to be the problem is in our side. 'Structure Search' license would not have been needed, because JChem Base license contains this. I will come back soon with the solution.

Hi,

I sent on a license to cover for this bug until we can release a fix.

Cheers/Alex

Hi,

we sent you a new license file directly. Please inform me the result of using.

Thank you, Edvard

Hi Edvard:

I have received the new license, and it works well via your API. Thanks a lot.

One last question concerns the license security, if I want to use the license with MarvinSketch, need some js code like this:

msketch_param("licenseFile", "https://www.yourserver.com/chemaxon/license.cxl");

But js code is open to client, and someone may easily steal the license by reading the html source code.

How can I avoid this?

Hi,

One last question 

concerns the license security, if I want to use the license with 

MarvinSketch, need some js code like this:


 msketch_param("licenseFile", "https://www.yourserver.com/chemaxon/license.cxl");


But js code is open to client, and someone may easily steal the 

license by reading the html source code.

At the moment this is the only way to set the license for applet.

Could you send me your merged license file? (Academic + free web ) We could have reproduced your issue neither the academic nor the free web license. Did you try to use the webapp just with the freeweb license?
