How to render PDF from Local File System

Hi,
Our code to render PDF form is as follows
__________________________________________________________________________________________ __________________________________________
Properties connectionProps = new Properties();
connectionProps.setProperty(ServiceClientFactoryProperties.DSC_DEFAULT_SOAP_ENDPOINT, "http:\\end point url");
connectionProps.setProperty(ServiceClientFactoryProperties.DSC_TRANSPORT_PROTOCOL,ServiceC lientFactoryProperties.DSC_SOAP_PROTOCOL);
connectionProps.setProperty(ServiceClientFactoryProperties.DSC_SERVER_TYPE, "WebSphere");
connectionProps.setProperty(ServiceClientFactoryProperties.DSC_CREDENTIAL_USERNAME, "admin");
connectionProps.setProperty(ServiceClientFactoryProperties.DSC_CREDENTIAL_PASSWORD, "password");

ServiceClientFactory myFactory = ServiceClientFactory.createInstance(connectionProps);
FormsServiceClient formsClient = new FormsServiceClient(myFactory);

String formName = "/ManualGEAC.pdf";
byte[] cData = "".getBytes();

Document oInputData = new Document(cData);
PDFFormRenderSpec pdfFormRenderSpec = new PDFFormRenderSpec();
pdfFormRenderSpec.setCacheEnabled(new Boolean(true));
URLSpec uriValues = new URLSpec();

uriValues.setContentRootURI("http://10.145.86.201:9080/PANBaseApp/forms");

FormsResult formOut = formsClient.renderPDFForm(
formName, //formQuery
oInputData, //inDataDoc
pdfFormRenderSpec, //PDFFormRenderSpec
uriValues, //urlSpec
null //attachments

Document myData = formOut.getOutputContent();
__________________________________________________________________________________________ ___

In the above snippet the setting of ContentRootUrl is not working. At the given line :
__________________________________________________________________________________________ ___
uriValues.setContentRootURI("http://10.145.86.201:9080/PANBaseApp/forms");
__________________________________________________________________________________________ ___

Can anybody help me to set the content root url as the local file path of the Pdf form.

Thanks,
Saravanan
