Error on client

Hi Folks, we have a server here running on Suse 10.3 and PLESK. On the system a PHP 5.2.6 and XSL extension ist installed. Building the WSO was already some trouble, but finally it works (almost). PHP Info says: wsf support enabled Directive Local Value Master Value wsf.attachment_cache_dir /tmp /tmp wsf.enable_attachment_caching 0 0 wsf.home /usr/lib64/php5/extensions/wsf_c /usr/lib64/php5/extensions/wsf_c wsf.log_level 6 6 wsf.log_path /tmp /tmp wsf.rm_db_dir /tmp /tmp xml XML Support active XML Namespace Support active libxml2 Version 2.6.30 xsl XSL enabled libxslt Version 1.1.20 libxslt compiled against libxml Version 2.6.30 EXSLT enabled libexslt Version 1.1.20 The SOAP Server is doing his job very well. We tested this by use of SoapUI. But the client will not...

The proxy call itself just return NULL, there is no exception. Do I need xsl.so here? Seams XSL is already included in our PHP build, so I commented it out on php.ini (if I comment it in, I will get a error [undefined symbol: dom_node_class_entry] on apache restart). Could anybody help please? We have also two Debian machines for development. Everything is doing fine here... Thank you in advance! Markus
