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](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

```auto
<?xml version="1.0" encoding="utf-8"?>
<jnlp spec="1.0+" codebase="http://proconf-dc01:8180/DSPC/">
   <information> 
      <title>ProConf Servoy Client</title>
      <vendor>Servoy</vendor>
      <homepage href="http://www.servoy.com/"/>
      <description>Database client</description>
      <icon href="lib/images/servoy_client_icon.png" />
      <icon kind="splash" href="lib/splashclient.png" width="64" height="64"/>
      <shortcut online="false">
      <desktop/>
    </shortcut>
   </information>
   <resources>
      <j2se version="1.8" java-vm-args="-XX:SoftRefLRUPolicyMSPerMB=3600000" />
      <jar href="bootstrap.jar" main="true" version="15" download="eager"/>
   </resources>
   <application-desc main-class="com.servoy.bootstrapper.Bootstrap">
      <argument> __DATASUTRA__ </argument>
      <argument>bootstrapthreadpoolsize:8</argument>
	</application-desc>
	<security>
   	<all-permissions/>
	</security>
</jnlp>

```

when launching this JNLP, it errors like this

```auto
java.io.IOException: Server returned HTTP response code: 500 for URL: http://proconf-dc01:8180/DSPC/servoy-client/ __DATASUTRA__.jnlp

```

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

```auto
      <jar href="lib/commons-codec.jar" version="1528362325793" download="eager"/>
      <jar href="lib/jcifs.jar" version="1528362325793" download="eager"/>
      <jar href="lib/httpclient.jar" version="1528362325793" download="eager"/>
      <jar href="lib/httpcore.jar" version="1528362325793" download="eager"/>
      <extension name="beans_molecule.jar" href="servoy-client/beans/molecule.jar.jnlp" version="1484750194853"/>
      <extension name="beans_htmlbean.jar" href="servoy-client/beans/htmlbean.jar.jnlp" version="1484750212135"/>
      <extension name="beans_jpedal_lgpl.jar" href="servoy-client/beans/jpedal_lgpl.jar.jnlp" version="1362737727000"/>
      <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

```auto
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. ![8)]( "Cool") on them so that they can still run my solution from Servoy 7.4.11 server (running elsewhere on network)

Sorry & thank you!
