You have various options, depending on what you want to achieve:

There are various things which can bite you with the WebView component. Check the following:

  • Verify the WebView is properly sized (e.g. same size as parent container) as the initial content might be sized 0px...
  • Make sure you granted INTERNET permission
  • Explicitly enable JavaScript

Hi Tosh,

it seems your path is not correctly setup as the process is not able to identify the underlying C binding libraries. I assume you are using the 64-bit version of Python. Also I want to point out that we currently only support Python 3 up to version 3.3 as later versions introduced quite significant changes in string handling. We are working on supporting versions beyond 3.3 at the moment.



While it is true that Generics are not supported by the Java Gateway I would like to provide a little more guidance on why that is the case and how to deal with this not uncommon situation.

Interesting thought Sebastian.

We haven't run dedicated benchmarks on this topic, but I can provide some guidelines.  You have to acknowledge that creating a dynamic object or a dynamic array is the most expensive part of your code style compared to just using plain variables. You are instantiating an object.

If you run a simple benchmark like the following you can observe a difference:

Embedding a JLNP file in a CSP page is the same as in a plain HTML page. You have to embed and load the JLNP file using something like the following snippet:


<script src=""></script>
    var attributes = {} ;
    <!-- Base64 encoded string truncated below for readability -->
    var parameters = {jnlp_href: 'your_applet.jnlp',
        jnlp_embedded: 'PCEtLSANCi8qDQogKiBDb ... bmxwPg=='
    } ;
    deployJava.runApplet(attributes, parameters, '1.8');


Hi Lucas,

I suggest you open a WRC case with Support so that we can look into the details of what is happening here. This may be a problem specific to the environment.



Hi Jules,

which Perl distribution are you using? We do support the ActiveState Perl distribution. Also, ensure that you are using a bitness version that matches the bitness of your Caché instance (64-bit in your case).



Hi Simcha,

you can easily retrieve the data that you are using in your layout (AlerTList in your case), by calling the function getSourceData() on your documentView component. Assuming the id of your documentView is 'mainView', the following code sample should work in your environment:

var view = zen('mainView');

var data = view.getSourceData();
