vWorkspace 7.5 web access now supports multiple web sites, when the Java Connector is installed the java components are automatically applied to any new web sites that are created.
Web sites created prior to installing the Java Connector will not automatically get the Java components.
To ensure that existing websites have the required Java Components there are 2 workarounds:
You can manually copy the files, follow these steps:
Delete/remove any vWorkspace web access from the server that were present prior to the Java Connector install, then recreate the sites using the same settings and the Java components will now be applied.
This is the default installation behaviour for the vWorkspace 7.5 Java Connector, this will be changed in the next vWorkspace release so that all web sites will automatically get the Java components.
