Hi Remy,
I set up a test case and it looks like it's a Tomcat-5 problem.
The webapp works on Tomcat-4.1, on Tomcat-5.0 the resources within
xsd.resources.jar cannot be reached.
tested environment: Win2k Prof, SuSE Linux 8.2

This is how the URI to the xsd resource in xsd.resources.jar is created
(from XSDSchemaImpl.java):
String baseURL = XSDPlugin.INSTANCE.getBaseURL().toString();
getGlobalResourceSet().getLoadOptions().put("XSD_MAGIC_XML_SCHEMA",
XSDConstants.SCHEMA_FOR_SCHEMA_URI_2001);
Resource magicSchemaForSchema2001Resource =
getGlobalResourceSet().getResource
(URI.createURI(baseURL +
"cache/www.w3.org/2001/MagicXMLSchema.xsd"), true);

Hi Remy, sorry for not sending you a test case, there were some high priority tasks coming in which had to be served first. As it looks now I will be able to set up a test case within the next 2 days.

Hi Remy, > The first thing to check is if the specified file exists, and if it > still fails, provide a test case. > loading seems to work only partially: the structure of the jar file is org/eclipse/xsd/plugin.properties org/eclipse/xsd/cache/www.w3.org/2001/MagicXMLSchema.xsd ... plus many more dtds + XML schemata while tomcat-5.0.5 loads plugin.properties to loader/org/eclipse/xsd/plugin.properties it does not load MagicXMLSchema.xsd. The only file that exists in Tomcats loader directory is plugin.properties. Best regards, Jan
tomcat-5.0.5 cannot access jar resources in WEB-INF/lib but only unzipped in WEB-INF/classes
Hi, tomcat-5.0.5 cannot access jar resources in WEB-INF/lib but only unzipped in WEB-INF/classes: The eclipse XSD API xsd.jar (http://www.eclipse.org/xsd/) provides a set of XML schemata + dtds in an additional jar file xsd.resources.jar. Both jar files (xsd.jar + xsd.resources.jar) are located in WEB-INF/lib While Tomcat 4.1.24 can access the resources in xsd.resources.jar Tomcat 5.0.5 throws an exception: ### Wrapped exception java.io.FileNotFoundException: C:\ApacheGroup\jakarta-tomcat-5.0.5\work\Catalina\localhost\xapp_simple\load er\org\eclipse\xsd\cache\www.w3.org\2001\MagicXMLSchema.xsd (The system cannot find the path specified) at java.io.FileInputStream.open(Native Method) at java.io.FileInputStream.(Unknown Source) at org.eclipse.emf.ecore.resource.impl.URIConverterImpl.createFileInputStream(U RIConverterImpl.java:416) at org.eclipse.emf.ecore.resource.impl.URIConverterImpl.createInputStream(URICo nverterImpl.java:382) ### If xsd.resources.jar is unzipped in WEB-INF/classes Tomcat 5.0.5 can access the resources. Is this a bug of Tomcat 5.0.5 or is it a problem of the emf eclipse package ? Thanks + best regards, Jan Harmsen Software AG The XML company
