// OpenCms properties creation example
// by David Sánchez Hernández [1]
List properties = new ArrayList();

// Setting template_elements property
CmsProperty prop = new CmsProperty();
prop.setName(CmsPropertyDefinition.PROPERTY_TEMPLATE_ELEMENTS);
prop.setValue("/system/modules/xxxxx.jsp",CmsProperty.TYPE_SHARED);
properties.add(prop);

// Setting title property
prop = new CmsProperty();
prop.setName(CmsPropertyDefinition.PROPERTY_TITLE);
prop.setValue("Title",CmsProperty.TYPE_SHARED);
properties.add(prop);

//get the fixed up filename as shown in CmsNewResourceUpload
String newResname = cmsObj.getRequestContext().getFileTranslator()
                          .translateResource(path + filename);

int resTypeId = OpenCms.getResourceManager()
                   .getDefaultTypeForName(newResname).getTypeId();

cmsObj.createResource(newResname, resTypeId, content, properties);
cmsObj.unlockResource(newResname);
cmsObj.publishResource(newResname);

You can also try looking at CmsNewResourceUpload.java from the OpenCms sourcecode. It's available from opencms.org via an interactive html browser.
