[opencms-dev] Programatically loading Structured Content

[Roman Uhlig]

Here are some snippets of our code which might help answering your questions:

1. Dynamically switching projects

CmsJspLoginBean cms = new CmsJspLoginBean(pageContext, request, response);
CmsObject cmso = cms.getCmsObject();
cmso.getRequestContext().setCurrentProject(cmso.readProject("MyProject"));

2. Creating resources

int m_restype_folder_id;
int m_restype_customxmlpage_id;

CmsResourceManager res_manager = OpenCms.getResourceManager();
try {
	m_restype_folder_id = res_manager.getResourceType("folder").getTypeId();
	m_restype_customxmlpage_id =
res_manager.getResourceType("MyXmltype").getTypeId();
} catch (CmsLoaderException e) {
	log.error(e.getMessage());
}

CmsJspLoginBean cms = new CmsJspLoginBean(pageContext, request, response);
CmsObject cmso = cms.getCmsObject();

cmso.createResource(s_uri_folder, m_restype_folder_id);
cmso.writePropertyObject(s_uri_folder, new CmsProperty("Title", "New
Folder", null));
cmso.writePropertyObject(s_uri_folder, new CmsProperty("NavText", "New
Folder", null));
cmso.unlockResource(s_uri_folder);
cmso.publishResource(s_uri_folder);

cmso.createResource(s_uri, m_restype_customxmlpage_id);
cmso.writePropertyObject(s_uri, new CmsProperty("Title", "New XmlContent",
null));
cmso.unlockResource(s_uri);
cmso.publishResource(s_uri);


Feel free to ask if you have difficulties with parts of the code.
