[jbossseam-issues] [JBoss JIRA] Created: (JBSEAM-957) Support transaction interceptor with JavaBeans and custom servlets
Support transaction interceptor with JavaBeans and custom servlets
------------------------------------------------------------------
Key: JBSEAM-957
URL: http://jira.jboss.com/jira/browse/JBSEAM-957
Project: JBoss Seam
Issue Type: Feature Request
Components: Core
Reporter: Christian Bauer
Priority: Minor
I'm using <web:context-filter url-pattern="/files/*"/> and a custom
FileServlet:
This works:
@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
String id = request.getParameter("fileId");
NodeDAO nodeDAO = (NodeDAO)
org.jboss.seam.Component.getInstance("nodeDAO");
org.jboss.seam.wiki.core.node.File file;
UserTransaction userTx = null;
try {
userTx = Transactions.getUserTransaction();
userTx.begin();
file = (id != null && !"".equals(id)) ?
nodeDAO.findFile(Long.getLong(id)) : null;
userTx.commit();
} catch (Exception ex) {
try {
if (userTx != null) userTx.rollback();
} catch (Exception rbEx) {
rbEx.printStackTrace();
}
throw new RuntimeException(ex);
}
This doesn't work because no JTA transaction is active when my JavaBean DAO is called
(all methods there are annotated @Transactional):
@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
String id = request.getParameter("fileId");
NodeDAO nodeDAO = (NodeDAO)
org.jboss.seam.Component.getInstance("nodeDAO");
org.jboss.seam.wiki.core.node.File file = (id != null &&
!"".equals(id)) ? nodeDAO.findFile(Long.getLong(id)) : null;
The Seam (seamspace) examples use EJB components, so this probably never came up before.
