Email queue on java

Hello, first of all I'm new to Java. We've a service written with PHP which sends a lot of emails to our users. Right now all new email messages added to MongoDB and by cron script(PHP) we send them out. I'm trying to implement a Mail Queue Daemon with Java, so it could process them asynchronous and without cron script. (We need to remove delays with cron, and if we will call php script faster, we will stuck in a concurrency with fetching, sending, removing emails from Mongo)
The question is does Java community have any kind of class I can use or should I write it from scratch? I would appreciate any advices.
Thanks.

Well, sorry for not replying sooner. I wrote a little script, it works as I wanted to and everything good, except the size. I put it on github please take a look maybe i missed something or it can be tune. I tested it with hundreds of emails to be sent, and postfix log showed that for each email my daemon creates new connection. I didn't find how to use persistent connection with JavaMail, but i actually haven't searched it yet &) But what is more important is ps -aux on our freebsd:
PID USERNAME THR PRI NICE SIZE RES STATE C TIME WCPU COMMAND
68094 root 18 44 0 *1208M* 32388K ucond 0 0:01 0.00% java
1G for simple script? this is when it just waiting and not sending mail. How it can be optimized?
2DrClap I prefer to name it daemon because it runs and lives permanent and not using cron. I dunno about threads, but i believe if we will send ~10k and more emails per hour, would be better to use threads, I don't want situation when client registering on site and waiting for five mins when activation email arrives. And as I mention above and as you can see in script we use Mongo, its fast. Really fast. I generate 100k emails for test in ~1 second. So Mongo isn't bottleneck and will never be.

UCCX email queue stuck in "loading"

I just created a new email queue and added it to a test agent and when the agent logs in to CAD the tab for the email queue says "Loading" but it never loads. The phone queue for the test user works normally. IMAP is enabled on Exchange and the service has been restarted.
Using:
Exchange 2013
UCCX version: 10.5.1.10000-24
CUCM version: 10.5.2.10000-5
I am able to telnet to the Exchange server on port 143 with the username/password configured on CDA.
Using Windows 7 and Java 7u51. Tried deleting Java and opened the client and had CAD download the Java version it needed.
Any suggestions would be appreciated.
Thanks

The Cisco CAD Troubleshooting Guide for Cisco Unified Contact Center Express, Release 10.5 covers this on page 101.
Problem Agent E-Mail does not work. The Agent E-Mail applet displays a “Loading...” animation that never completes. If you turn on the Java Console with Tracing, Logging, and Applet life cycle exceptions enabled, you can see the following message during Agent E-Mail start up:
security: LiveConnect (JavaScript) blocked due to security settings.
Cause. With Java 7 Update 25, Oracle introduced a feature that blocks LiveConnect when the user’s JRE does not meet the JRE security baseline. The security baseline is published by Oracle and updated as security vulnerabilities are fixed in newer JRE updates. When the Agent E-Mail applet starts, the JRE checks this security baseline. If the required JRE is higher than the JRE version the user is currently running, or if the security baseline cannot be found and the current JRE is expired, Agent E-Mail no longer works.
Solution JRE 1.7 Update 45 is no longer supported due to Oracle changing the security baseline. You must update to JRE 1.7 Update 51 or later. Future JRE updates might render Agent E-Mail unusable due to the LiveConnect blocking feature and the security baseline. If this is the case, you must perform one of the following workarounds:
■ Update each user’s JRE version to meet the security baseline.
■ Move the security slider of each user’s Java Control Panel to a
setting lower than High
■ Add Cisco Agent Desktop to the Exception Site List. For more information, refer to the following Oracle documentation:
http://docs.oracle.com/javase/7/docs/technotes/guides/jweb/ex ception_site_list.html
■ Create a Deployment Rule Set (DRS) and distribute it throughout the contact center. For more information on how to create and distribute your own DRS, refer to the following Oracle documentation:

UCCX email queues

Hi,
We have been in the process of configuring email queues for our CCX 8.5 environment with exchange 2010, all configurations look good now and we are posed with the issue of users being stuck in either email not ready state or email logout state.
The agent email tab in desktop administrator is stuck on loading.
anyone come across issues similar to this?
Regards,
Scott

Hi Scott,
Wanted to verify where the issue is, you wote the following
Scott Brien wrote:The agent email tab in desktop administrator is stuck on loading.
Do you mean when you login to Cisco Desktop Administrator and try to configure the Global Settings? Or do you mean the actual CAD client is stuck loading the Agent Email Applet and no emails are being sent to the agents?
Depending on the exact problem you may want to try a couple of things out;
Be sure that the correct version of Java is installed on the agent PC, the best way to complete this is to uninstall all Java versions from the agent PC, then load CAD and allow CAD to download the version it needs to work correctly, Java 1.6.0 update 17. Then configure Java for CAD per the following guide, page 76
http://www.cisco.com/en/US/docs/voice_ip_comm/cust_contact/contact_center/crs/express_8_5/installation/guide/cad85ccxig-cm.pdf
If agents are still not able to receive emails, you may need to add "send as" permissions for the user that is configured in CDA under the Global Settings on Exchange, see page 93

Then do so...
You'll probably want to use the JavaMail API (http://java.sun.com/products/javamail) to do that.

HTML tags in emails sent through java

Hi all,
I am trying to send an email through my java code. I have set the content type of email to html. It is working fine for the html tags like <tm>,<head>,<table>,<td> etc but it is not working for the tabs whic set color ,border etc. <font color=#fffd"dd> ,<table border ="10"> etc
How to enable this tags in java. What kind of API's i need to use for it.
Hope my question is clear to all of you.
Any pointers in this regard will be very helpful.
Thanks,
Abhishek chowdhury

I am trying to send an email through my java code.No problem. As long as you construct the message correctly it should work.
I have set the content type of email to html. It is working fine for the html tags like <tm>,<head>,<table>,<td> etc but it is not working for the tabs whic set color ,border etc. <font color=#fffd"dd> ,<table border ="10"> etcSo you haven't constructed them correctly.
How to enable this tags in java.Java neither knows nor cares what is in a message body that it is sending. It is up to you.
What kind of API's i need to use for it.I doubt that you need any APIs. Just construct the HTML correctly.
Hope my question is clear to all of you.It's not, because the problem has nothing to do with Java and everything to do with your programming.

It seems to be doing a JNDI lookup, and you haven't configured JNDI properly. Exactly how to do this depends on what JNDI provider you are using. Earlier in the thread you mentioned you were using WebLogic, so the answer may lie in the WebLogic documentation.

New iPad cannot get email to work java errors?

New iPad cannot get email to work java errors?

"Javascript" is not "java", two completely separate and different programming languages. So you are not getting "java errors". If you are using a browser to get your email then likely there is broken javascript code at the server.

UCCX finesse email queuing without deploying Socialminer

we had a question as part of a UCCX upgrade to 10.5.
Is it possible for us to use Finesse as an Agent to do Email queuing, without needing to setup Socialminer ?
In that case, how would email integration/relay work ? how would Finesse connect with Exchange 2012 ?
Thanks

Hi
No - if you are using Finesse, you need SocialMiner to add all multi-channel capabilities (e.g. chat, email)
If you are using CAD you don't need SM as it uses the legacy service for CAD.

Need special encoded characters in an Email subject with java 1.3.1_02

I need to find a way to construct an Email through java with Subject lines built using characters from various Asian encodings. Such as Shift-JIS, Chinese Big5, etc.
These encodings cannot be in UTF-8 format and must remain in the native character set.
For testing I have an HTML file constructed using a single line of text with Shift-JIS characters. This file shows properly in web browsers under the Shift-JIS encoding view, and when used to create the body of an email it works perfectly through the DataHandler. However, I cannot get any java Reader to pull the same stream of characters into the Subject of the email. The Subject is always garbage no matter what I do.
Here is a small code sample with the relevant lines:
Session session = Session.getDefaultInstance(System.getProperties(), null);
MimeMessage reSend = new MimeMessage(session);
Transport ship = session.getTransport();
BufferedReader s = new BufferedReader(new InputStreamReader(new FileInputStream("C:\\JavaPrograms\\Converted\\JISConv.html"), "SJIS"));
String resub = s.readLine();
s.close();
reSend.setSubject(resub);
DataHandler collect = new DataHandler(new FileDataSource("C:\\JavaPrograms\\Converted\\JISConv.html"));
reSend.setDataHandler(collect);
ship.send(reSend);If I use the "SJIS" encoding in the InputStreamReader above, all characters are shown as "?". If I delete it entirely and use the system default, I get half of the characters and the rest are garbage. I can generate either of those results using various other Japanese and Western encoding definitions.
I have tried using the above code, also DataHandlers for the Subject, FileReader directly to a String, ByteArrayInputStreams, and StringBuffers. So far everything I try ends up at the same result.
Can anyone help me out? I really need this to work. If I can get this one encoding to work, then I should be able to program case switches for the other encodings.
Thanks kindly!
Kurt Jackson

First this is an issue with javamail and not with java.
What makes you think that the mime standard allows what you want to do?
Both of your 'tests' have been done using alternatives which do support alternative encodings.
These encodings cannot be in UTF-8 format and must remain in the native character set.That seems rather unlikely to me. Email is transported using one encoding. Certainly SMTP uses only ascii. So what ever you put in there is going to be ASCII no matter what you do to it. I suppose something at the end might try to read it using an alternative encoding but then what happens when someone really wants to send those ASCII characters?
Mime, I believe, is built on SMTP. And the subject line is still SMTP and thus ASCII.
Here is one link that covers mime (you might want to check the backing references though.)
http://www.mindspring.com/~mgrand/mime.html
I believe there is some sort of official or unofficial standard for doing what you want. I would suggest that you start by getting that first. I would suspect JavaMail doesn't support it.
Once you have a standard to follow you have the following choices..
- Modify JavaMail directly to support this (this then becomes a non-distributable solution.)
- Extend JavaMail do support this. This might or might not be possible.
- Write your own implementation (don't use JavaMail.)
- Find another solution from another source that already implements this.

Need to publish message from database to a JMS Queue using Java

I need to publish messages to a Websphere JMS Queue whenever any changes happen on a particular column of a table in oracle 11g. For that I have written a trigger on that particular table which in turn will invoke one java procedure. I have written the java procedure using a standalone java class and uploaded the java class as a schema object. While executing the procedure it is throwing error as it is not able to instantiate some of the java classes. I don't know how to provide the reference of different jar files while executing the java class. Can anyone help me on this.

Welcome to the forum!

Clarify your statement. First you say 'standalone java class' but then you talk about instantiating java 'classes' and referencing 'different jar files'. If you are executing your Java class inside Oracle then any Java classes that your java class is referencing also have to be loaded into Oracle or it won't be able to reference or execute them.
How do you plan to ' publish messages to a Websphere JMS Queue '? Where is this queue you are talking about?
Why are you using a Java procedure and class instead of PL/SQL?

Monitor Print Queue with java program

I'm plan to write a client/server based application which control the printing for every user. I've no idea how to start on the application.
1. Is it possible to monitor the print queue or print job using java application?
2. How does the server react if the client sending the print job to there? How's the client can trigger the signal during printing and send to the server?
Thank you!

I'm plan to write a client/server based application
which control the printing for every user. I've no
idea how to start on the application.You should establish feasibility first, before planning to write anything
1. Is it possible to monitor the print queue or print
job using java application?Not really. Print queues are highly system-dependent things and some e.g. Windows can really only be accessed via system calls in a native language.
2. How does the server react if the client sending
the print job to there?Err, it prints the file?
How's the client can trigger the signal during printing and send to the server? What signal?
But I suspect the answer to the first question makes the others irrelevant.
