Servoy Forum

Hi all,
I am not one to usually 'cross post' but I have had no response to my issue in this post
https://forum.servoy.com/viewtopic.php?f=16&t=21190&start=45#p125349
so I am having to re-post as this is now a major issue for me!
I am desperately trying to migrate my old Servoy 7 clients using 'Smart Client' [SC] to the latest Servoy release (currently 2023.12.2) so that I can gradually move them to TiNG, but allow them to carry on using SC until that is ready.
I have created solutions for them using the old DATASUTRA framework.
As a first step, I'm trying to get SC running from their server via Tomcat & a deployed WAR file, so have tried to use the 'bootstrapper' to do it.
I have edited the 'bootstrap.jnlp' file from the deployed context [DSPC] on the server & created this

<?xml version="1.0" encoding="utf-8"?>
<jnlp spec="1.0+" codebase="http://proconf-dc01:8180/DSPC/">

   </resources>
   <application-desc main-class="com.servoy.bootstrapper.Bootstrap">

      <argument>bootstrapthreadpoolsize:8</argument>
   </application-desc>
   <security>
      <all-permissions/>
   </security>
</jnlp>


when launching this JNLP, it errors like this

so it seems to be trying to just get the old style solution JNLP file...
Do I have to a <resources> line for each jar that is part of my solution like (snippet)??

      <extension name="beans_servoy_slider.jar" href="servoy-client/beans/servoy_slider.jar.jnlp" version="1589968180367"/>


I also tried to edit the 'bootstrap.jar' / bootstrap.properties file to

Code: Select all

codebase=http://proconf-dc01:8180/DSPC/
solution=__DATASUTRA__
bootstrapthreadpoolsize=8
#arg0=system.property.servoy.profilename:YourProfileName
#arg1=argument:owner:1
#arg2=owners:2
#jnlp.bootstrapper.home.dir=

and using that, but that also failed (tried running from terminal with "java - jar xxx" and got similar error to above exception.

[EDIT] I have now also tried using OpenWebStart (didn't work as Java didn't match) and with the very kind help of Robert Edelmann, I have tried with some stand alone 'bootstraps' with newer Java versions built in and it is still not working!
I am generating the WAR without the solution files on my M2 MacBook Pro, but deploying them on a Windows/PC Server.
Is there something special I should be doing when creating WAR file to make SC work??
Or something in the servoy.properties file I should be setting differently (I have not disabled start.rmi - see screenshot)??

Please advise what I am doing wrong??
(Clients are using Windows with Java 8 (1. on them so that they can still run my solution from Servoy 7.4.11 server (running elsewhere on network)

Sorry & thank you!
