Marvin 5.0+ license with Java Web Start

Hello,

We have a perpetual license for MarvinBeans. And we deploy our applications using Java Web Start.

My question is -- what is the best way to handle Marvin 5.0+ license file in conjunction with Java Web Start? I don't want our users to see "no license found" error message when clicking on the JNLP link we provided.

Thanks!

Hello,

we support a Java system property called "chemaxon.license.url" that can be set using the <property> tag in JNLP files.

With this parameter you can link the license file uploaded to the server.

The only criterium is, that you need licenses that have the "Server Use Allowed" field.

We will create an example and documentation about this in the near future.

I hope you can use this solution.

Kind regards,

Judit

Code:

Is this right?

Thanks!

Yes, this should be right, though the value should be tested.

Does this work for you?

I put it in. But how do I know it actually works?

Thanks!

For example run the Charge plugin from Tools > Charge > Charge.

The list of the available licenses is listed in the Chemaxon License Manager in Help > Licenses...

Hello,

We don't have plug-in licenses, but we have MarvinBeans license.

I went to Help > License... Under License overview or Product license details > Marvin Beans, I didn't see any entries. So I guess this property tag in JNLP does NOT work.

What should I do now?

Thanks!

Hello,

Code:

The current "value" is pointing to the absolute path of the license file that is stored on the jnlp server. Should I replace it with "http://........."?

Thanks,

In our test environment we are setting it with http:// and it works fine.

You need to be aware of the JWS caching, clear cache might help to get it work.

Hello,

Is it possible to set the MarvinBean's license through the code? If so, can you please provide the code example?

Thanks!

With this public API method the license file can be set:

http://www.chemaxon.com/marvin/help/developer/beans/api/chemaxon/license/LicenseManager.html#setLicenseFile(java.lang.String)

Did you have problems with the JNLP parameter?

Thanks!

Can I also use "setLicense" method by copying and pasting the content from the license.cxl file?

When should this method be used? Right after "new MSketchPane()" call?

That JNLP parameter works now, but I want to try set the license via the code.

It is possible with it, though be careful not to break the EULA ( http://www.chemaxon.com/marvin/license.html ) with this.

The call can be on any arbitrary location, it should not change the behavior.

OK.

I only need to call setLicense once and it'll work for both MSketch and MView, right?

Thanks!

Yes, using them in the same JVM it will work, because it is static.
