| There is an easy and elegant way to load DLLs from Applets and JavaWebStart Applications. | ||
|
|
||
| Both JavaWebStart and Applets support JNLP (Applets since 1.6.0_10 aka plugin2). | ||
| Within a jnlp file it is possible to specify a nativelib and that's it! | ||
| So what do you need to do? | ||
|
|
||
| 1.) package the jacob-1.XX-xXX.dll into a jar file (root level of the jar, not into a subfolder) and put it into your applications lib folder next to your other libs (e.g. jacob.jar) | ||
| 2.) Specify all your libraries in your jnlp file like this: | ||
|
|
||
| <?xml version="1.0" encoding="UTF-8"?> | ||
| <jnlp href="MyApplicaton.jnlp" spec="1.0+" version="1.1"> | ||
|
|
||
| <information> | ||
| <title>My cool Application or Applet</title> | ||
| <vendor>nepatec GmbH & Co. KG</vendor> | ||
| <offline-allowed /> | ||
| </information> | ||
|
|
||
| <security> | ||
| <all-permissions/> | ||
| </security> | ||
|
|
||
| <resources> | ||
| <j2se href="http://java.sun.com/products/autodl/j2se" version="1.6.0_10+" /> | ||
| <jar href="MyCoolApp.jar" main="true" version="1.0.0" /> | ||
| <jar href="jacob.jar" version="1.0.0" /> | ||
| <nativelib href="jacob-1.XX-xXX.jar"/> | ||
| </resources> | ||
|
|
||
| <!-- Use either this for an applet --> | ||
| <applet-desc | ||
| name="MyCoolApp" | ||
| main-class="de.nepatec.app.MyCoolApplet" | ||
| width="265" | ||
| height="60"> | ||
| </applet-desc> | ||
|
|
||
| <!-- or this for an web start application --> | ||
| <application-desc main-class="de.nepatec.app.MyCoolApp"> | ||
| <argument>some crazy arguments</argument> | ||
| </application-desc> | ||
| </jnlp> | ||
|
|
||
| 3.) Sign all the jars or set up a policy file (cp. Applet Security below) | ||
| 4.) Deploy your application and start it via webstart or as an applet (from an webpage) | ||
|
|
||
|
|
||
| General comments: | ||
|
|
||
| - If you sign the jar files you need the <security> tag - when using a policy file it can be removed | ||
| - furthermore it is recommended that all libs are signed with an official certificate (e.g. from verisign, thawte etc) so that the browser doesn't pop a warning stating 'untrusted' application... | ||
| - to check the validity of your jnlp file the tool JaNeLA (link cp. sources below) is recommended. | ||
