Convert java code to coldfusion code (CFIMAP)

问题:

I am trying to setup a connection to an office365 mailbox. This function is based on a java example (see https://stackoverflow.com/a/28689722/2482184). I am almost done but i cannot figure out how to convert the following line of code which is in the orignal java example:

Message[] messages = inbox.search(new FlagTerm(new Flags(Flags.Flag.SEEN), false)); 

Below the full function:

<cfscript>     mailSettings = {};     mailSettings.server = "outlook.office365.com";     mailSettings.port = "993";     mailSettings.username = "xxxx";     mailSettings.password = "xxxx";     mailSettings.action = "";     mailSettings.folder = "INBOX";     mailSettings.timeout = 5000;      properties = createObject("Java","java.util.Properties");     jsession = createObject("Java","javax.mail.Session");     store = createObject("Java","javax.mail.Store");     message = CreateObject("Java", "javax.mail.Message");      properties.init();     properties.put("mail.store.protocol","imap");     properties.put("mail.from", mailSettings.username);     properties.put("mail.imap.port", mailSettings.port);     properties.put("mail.imap.connectiontimeout",mailSettings.timeout);     properties.put("mail.imap.timeout",mailSettings.timeout);     jsession = jsession.getInstance(properties);      store = jsession.getStore("imaps");     store.connect(mailSettings.server, mailSettings.username, mailSettings.password);      inbox  = store.getFolder("#mailSettings.folder#");     inbox.open( inbox.READ_ONLY );      /**********     NEED HELP TO CONVERT THIS LINE BELOW TO COLDFUSION SYNTAX     ---------     Message[] messages = inbox.search(new FlagTerm(new Flags(Flags.Flag.SEEN), false));     ---------     END NEED HELP     **********/      inbox.close(true);  </cfscript> 

I know there is a cfimap tag. I am trying to find a faster method to download emails.

Get a reference to Flag.SEEN

Flags.Flag - This inner class represents an individual system flag.

Then use it to build the other objects (Flags and FlagTerm):

Flag = createObject("java", "javax.mail.Flags$Flag"); Seen = createObject("java", "javax.mail.Flags").init(Flag.SEEN); Term = createObject("java", "javax.mail.search.FlagTerm").init(Seen, false); // do search ... messages = inbox.search(Term);

Create a MailFetch.java file.

imports .... .....  public class MailFetch {  public function fetchFolder(String server, String port, String username, String password, String foldername){       Session session = Session.getDefaultInstance(new Properties( ));     Store store = session.getStore("imaps");     store.connect(server, port, username, password);     Folder inbox = store.getFolder(foldername);     inbox.open( Folder.READ_ONLY );      ....      code goes here       .....      return messages; // Message[]  } 

}

Compile the file using javac

• Start Command Prompt.

• Navigate to the folder that holds your class files:

  C:>cd \mywork

• Set path to include JDK’s bin. For example:

  C:\mywork> path c:\Program Files\Java\jdk1.8.0_121\bin;%path%

• Compile your class(es):

  C:\mywork> javac *.java

• Create a manifest file and your jar file:

  C:\mywork> jar cvfm Craps.jar manifest.txt *.class

copy the jar to \ColdFusion\cfusion\wwwroot\WEB-INF\lib or \ColdFusion\cfusion\lib

restart Coldfusion service

Access using

mailobj = createObject("java","com.your.path.MailFetch");  messages = mailobj.fetchFolder("outlook.office365.com", "993", "xxxx", "xxxx", "INBOX"); 

you can try this also

<cfexchangeConnection action="open" username="xxxx" password="xxxx" port="993" server="outlook.office365.com" connection="testconn1">  <cfexchangemail action="get" name="inbox" connection="testconn1" folder = "INBOX"></cfexchangemail>  <cfexchangeConnection action="close" connection="testconn1">

Below the actual function i have written, partly based on Ageax answer. It is way faster then CFIMAP but still not as fast as i would like it to be. Implementation of the fetch method could really speed things up. I placed my implementation of the fetch command between /* */ because it does not work. I guess i am doing something wrong. If someone knows how to properly implement this method i would be very grateful.

<cfscript> function fecthImap() {     var local = {};      local.settings = {};     local.settings.server = "outlook.office365.com";     local.settings.port = "993";     local.settings.username = "xxxx";     local.settings.password = "xxxx";     local.settings.action = "";     local.settings.folder = "INBOX";     local.settings.timeout = 5000;     local.settings.tick = GetTickCount();     local.settings.x = 1;      local.java = {};     local.java.properties = createObject("Java","java.util.Properties");     local.java.properties.init();     local.java.properties.put("mail.store.protocol","imap");     local.java.properties.put("mail.from", local.settings.username);     local.java.properties.put("mail.imap.port", local.settings.port);     local.java.properties.put("mail.imap.connectiontimeout",local.settings.timeout);     local.java.properties.put("mail.imap.timeout",local.settings.timeout);      local.java.session = createObject("Java","javax.mail.Session");     local.java.session = local.java.session.getInstance(local.java.properties);      local.java.store = createObject("Java","javax.mail.Store");     local.java.store = local.java.session.getStore("imaps");     local.java.store.connect(local.settings.server, local.settings.username, local.settings.password);      local.java.folder  = local.java.store.getFolder("#local.settings.folder#");     local.java.folder.open( local.java.folder.READ_ONLY );      local.java.mailFlags = createObject("java", "javax.mail.Flags$Flag");     local.java.mailFlagsSeen = createObject("java", "javax.mail.Flags").init(local.java.mailFlags.SEEN);     local.java.mailFlagTerm = createObject("java", "javax.mail.search.FlagTerm").init(local.java.mailFlagsSeen, false);      local.java.messages = local.java.folder.search(local.java.mailFlagTerm);      /*This part could realy speed thinks up, but it does not work as expected*/     /****************************     local.java.profile = createObject("Java","javax.mail.FetchProfile");     local.java.profileItem = createObject("Java","javax.mail.FetchProfile$Item");     local.java.profile.add(local.java.profileItem.ENVELOPE);     local.java.folder.fetch(local.java.messages, local.java.profile);     ****************************/      for(local.settings.x=1;local.settings.x<=arraylen(local.java.messages);local.settings.x=local.settings.x+1)     {         local.java.message =  local.java.messages[local.settings.x];         WriteOutput(local.settings.x & ':' & GetTickCount()-local.settings.tick  & ':' & local.java.message.getSubject() & '<br>');     }      local.java.folder.close(true); } fecthImap(); </cfscript>
