Imported archive : issues in loading referenced XSDs

Question

hello experts,
I am validating XML messages in XI using a Java mapping and by loading the XSDs at runtime.
I am facing a typical problem when my XSDs import / include other XSDs and below is the situation.
I have a Java mapping class say Validator in a package
com.myclient.xiutils.
I have XSDs in a folder inside this package which is
com.myclient.xiutils.xsds
Within the Validator class, I load the XSDs using the statement,
InputStream schemaInputStream =
               this.getClass().getResourceAsStream("xsds/primary.xsd");
There is no issue if the primary.xsd has everything inside it but in my case, the third party has provided the xsds to us and the primary.xsd has a reference (import) to secondary.xsd.
whichever location in the package structure I put the secondary.xsd, XI does not recognize it and errors out saying unable to find secondary.
The workaround I had used was I copied the secondary.xsd to the location pointed by the environment variable user.dir and XI could find it at runtime but I want to know what is the correct way.

Hi Amol,
May be you could try the following lead to resolve the problem:
Lets assume your primary.xsd in the package com.myclient.xiutils.xsds has the following line within it
<xsd:import namespace="..." schemaLocation=
"com/myclient/xiutils/xsds/secondary.xsd"/>
In such a case I assume, the following would happen: Your java runtime would look for the secondary XSD under the following path
+com.myclient.xiutils.xsds.com.myclient.xiutils.xsds.secondary.xsd+.
The underlined path is the path for the primary.xsd, followed by the path of secondary.xsd. If this guess is right, then simply changing the schemaLocation to "secondary.xsd" would help.
