我正在使用My Java Web Application(JSF)打开outlook并附加文件. Methd只工作一次,当我再次尝试调用Method时,我得到:
org.eclipse.swt.SWTException: Invalid thread access
这是我的方法:
public void sendemails() {
Display display = Display.getCurrent();
Shell shell = new Shell(display);//Error is Happening on this Line.
OleFrame frame = new OleFrame(shell, SWT.NONE);
// This should start outlook if it is not running yet
OleClientSite site = new OleClientSite(frame, SWT.NONE, "OVCtl.OVCtl");
site.doVerb(OLE.OLEIVERB_INPLACEACTIVATE);
// Now get the outlook application
OleClientSite site2 = new OleClientSite(frame, SWT.NONE, "Outlook.Application");
OleAutomation outlook = new OleAutomation(site2);
OleAutomation mail = invoke(outlook, "CreateItem", 0 /* Mail item */).getAutomation();
setProperty(mail, "BodyFormat", 2 /* HTML */);
setProperty(mail, "Subject", "Testing");
setProperty(mail, "HtmlBody", "I am Sending to you");
ServletContext ctx = (ServletContext) FacesContext.getCurrentInstance().getExternalContext().getContext();
String path = (String) ctx.getAttribute("capturepath");
File file = new File(path);
if (file.exists()) {
OleAutomation attachments = getProperty(mail, "Attachments");
invoke(attachments, "Add", path);
} else {
FacesContext.getCurrentInstance().addMessage(
null,
new FacesMessage(FacesMessage.SEVERITY_INFO,
"Failed!",
"File " + path + " Does Not exists"));
}
invoke(mail, "Display" /* or "Send" */);
}
环顾四周后,我发现我应该创建一个这样的方法:
public void exec() {
Display.getDefault().asyncExec(new Runnable() {
@Override
public void run() {
sendemails();
System.out.println("Outlook called");
}
});
}
我有,但当我调用exec时没有任何事情发生.我可以排序这个无效的线程访问没有必要创建另一个方法?
