Java mail process hangs

Hi,
I am connecting to exchange server to read the mails. The program works fine but sometimes it just hangs.
The process hangs at "store = session.getStore("imap")".
Any help?
Thanks

Can you get a stack trace when the hang occurs?
The most common cause of hanging is trying to connect to a server that's not up.
You can set timeouts to control that.
But the getStore method is an entirely local method, it should not hang.

C++ process hangs when started from Java

I am trying to execute a c++ code from java on a remote Windows machine. In order to deal with the remote part, I have created a Web service from where the actual command is run using Runtime.exec(). The c++ exe is not being called directly from the java code. I have a batch file that eventually calls the exe.
The problem is, both java and c++ processes hang. The java code on server side does handle the output stream and error stream. Also, the c++ code is logging everything in a file on Windows. The strange thing is that, when I remove the WS call and run the java code on server side as a standalone java program, it succeeds. Also, execution of the batch file alone does not hang. Here is the java code:
public class RunCPlusPlusExecutable {
public int runExecutable() {
    int exitValue = 0;
    try {
        Process p = null;
        Runtime rt = Runtime.getRuntime();
        System.out.println("About to execute" + this + rt);
        p = rt.exec("c:/temp/execcplusplus.bat");
        System.out.println("Process HashCode=" + p.hashCode());
        StreamProcessor errorHandler = new StreamProcessor(p.getErrorStream(), "Error");
        StreamProcessor outputHandler = new StreamProcessor(p.getInputStream(), "Output");
        errorHandler.start();
        outputHandler.start();
        exitValue = p.waitFor();
        System.out.println("Exit value : " + exitValue);
        if (exitValue == 0)
            System.out.println("SUCCESS");

The WS server is running from some admin user. And I have been running the standalone java program from some other user. It seems that the c++ executable is giving referenced memory error when being executed from WS call. There are pop-ups citing the error with OK and Cancel buttons(visible when logged in as admin). The error states
The instruction at 0x05473030 referenced memory at 0x000001d4. The memory could not be read
Any idea what is causing the problem and how to debug it? Why does this memory error comes only when the exe is run through WS call? Please note that I won't be able to debug the c++ code and the web service is an apache axis2 service.
Thanks

How can I know? Its your environment, not mine. The only thing we know is that when running the stuff through one path things blow up and when you run them through another path, things don't blow up. User rights is an obvious suspect, but not necessarily the actual problem. Generally when rights are the problem, you get some form of "access denied" exception, not a code hang.
Another likely possibility is that of network settings; perhaps your server goes through a proxy and your local applications do not, or the other way around.
Yet another likely possibility is that the version of Java used is different, or different versions of libraries are no the classpath causing differences in behavior. There is only one way to figure it out: get to know your environment very well and through solid reasoning and experimentation try to figure out where the breaking point is. It all starts with answering this question: what might be different in the environment of the web server, and outside of it? I can't know, only you can. Good luck.

Using Java Mail API from Tomcat

Hello,
Purely as an academic exercise I have written a JSP page which, upon being requested from the client's browser, should send me a default email using Java Mail Api.
here is the code :
import java.util.*;
import java.io.*;
import javax.mail.*;
import javax.mail.internet.*;
import javax.activation.*;
public class TestMail {
    static String msgText1 = "success this time 12";
    static String msgText2 = "This is the text in the message attachment.";
    public String sendIt() {
        String to = "<my email";
        String from = "<anything>";
        String host = "<my ip address of smtp server>";
        boolean debug = false;
        Properties props = new Properties();
        props.put("mail.smtp.host", host);
        Session session = Session.getInstance(props, null);
.....The code works fine as a stand alone app but when called from JSP page it hangs on the Session.getInstance line. I can only guess that this might be a security issue with the container not allowing access to the smtp server ?
Can anyone give me a clue ???

Your Tomcat log files should spell out the problem for you.
My Tomcat installation does not come with the Java Mail API. I had to add the mail and activation jar files to the server/common.lib directory (or the server's shared/lib or the WEB-INF/lib of your application.)
HTH.

Sneak preview sp11 java edition install hangs

I posted this in the NetWeaver forum originally but now realize this might be a more appropriate forum.
I am trying to install the sneak preview sp11 java edition to a brand new box. The installation hangs on the "Load Java Database Content" step. The last thing in the jload.log is:
08.11.05 00:24 com.sap.inst.jload.Jload dbImport
INFO: table J2EE_CONFIGENTRY created
It's been running for 24 hours now and has not moved off that step. The java.exe process is using 50% cpu so it apparently thinks it's doing something. I've seen the posts regarding errors with the install and the Timezone change fix, but I'm already in a timezone that has DST.
Any ideas?

I had the same problem. I tried reinstalling a couple of times, but the same thing happened - the installation was just hanging and using 100% cpu time.
As the installation had not been tested with JDK 5.0 I had installed the newest version of 1.4.2, namely 1.4.2_10.
Then, just for kicks, I uninstalled 1.4.2_10 and installed 1.4.2_08 - 40 minutes later I got the "Successful install" screen.
I hope this helps.
ps: it should be noted that I installed on a freshly installed Windows XP (and later on a freshly installed Windows 2003 Server - also without problems) with German regional settings, just to make sure - I have later reverted the regional settings to my locale.

Problem with starting a sqlplus-process via java.lang.Process

Hi,
I want to start a sqlplus-Process from a java-application via java.lang.Process. Works great with XP. On a W2K-Machine, the process is started (I can see it in the Taskmanager), but it doesn't connect to the db - the OS-process hangs, also the java-application which invoked the process.
If I start a sqlplusw.exe-Process instead of sqlplus.exe, it works as well.
Does anybody know what's going wrong ?
I'm using java 1.5.0_11 and Oracle Database 10g Enterprise Edition Release 10.2.0.3.0
Thanks in advance
Jens

java.lang.Process can be used to perform an OS Shell to launch specific tasks. But why are you interested in specifically launching sqlplus from here?

Workflow Java Mailer - Where is it?

Hi,
I have installed Oracle Workflow Server Release 10.1.0.3 for Linux x86 standalone on a on a 10.1.0.4 database run the configuration assistant. The DAD is configured in the 10G Standalone HTTPD which i installed from the 10.1.0.3 companion CD and after sorting out a number of installation issues the installation was successful.
I have one missing component and that is the Java Mailer which is said to be 'included' with Workflow server 2.6.3 in the install notes:
Oracle® Workflow Installation Notes for Oracle Database Release 2.6.3 February 2004 Part No. B12169-01
Quote "Java-based Workflow Notification Mailer: The Notification System includes a Java-based program called a notification mailer, implemented as a service component within the Generic Service Component Framework, which communicates notifications to users via e-mail and interprets responses. Oracle Workflow provides one seeded notification mailer service component called the Workflow Notification Mailer. This program requires an outbound SMTP mail server and an inbound IMAP mail server"
after chasing my tail for hours trying to find where and how this components needs to be installed I came across 266612.1 which has some references to a. Oracle® Content Management SDK 10g (9.0.4.2.0) and Oracle® Application Server Integration 10g (10.1.2.0.0).
I have looked at the documentation for these two components and there is nothing specific mentioned about the Java Mailer, although workflow is mentioned amoung other things..
If someone could point me in the right direction i would be exceedingly grateful. What I thought was a simple exercise in getting workflow installed and being able to send emails using the standard workflow API's and turned into a monumental journey of frustration and utter waste of time which a customer is paying for.
Reading between the lines it looks like i need yet another installation of Oracle (the 10.1.2) application server along with the two components above.
Also, Workflow 2.6.4 is included in the 10G Release 2 Database companion CD. Is the Java Mailer included with this version?
My apologies if this post has come across somewhat indignant, I get annoyed when people flame in posts and then ask for help, but i am genuinely needing advice from someone who done the seemingly impossible.
regards,
Brenden

Sorry, for database installation there is a seperate application to manage workflow (can't remember the name but you can find it in the apache server middle tier or you can view "install" folder a WF***MANAGER.ear file in there, start up your apache and run it in your browser ).
The parameter you entered in config assistant for mailer isn't enough to get it working because you need some extra bits, for example the password and the path that points to processed folder and discard folder, etc. All of these bit can be set in workflow manager, remember don't keep looking for the JAR file for mailer, even if you found it you can do nothing about it unless you successfully run the workflow manager after installation.
Once you have the workflow manager up and running you shall be able to config the mailer in there.
List of steps: (if you go for silent installation you don 't need to do the post config in workflow manager anymore, and mailer shall be ready to run)
for wf shipped with DB
1. follow offical installation note
2. it will ask for a apache home to be used as middle tier
3. run through all steps
4. find Wf manager and run the config through the interface.
5. test the mailer in wf manager
I would like someone correct if wrong because I have no experience to set up wf server shipped with DB, but for the one shipped with CMSDK I can answer you alot.
Regards,
Kun

Please send me a fully working war file if any one have with the web server used ! Please I have to subit this as my assignment!

You might want to try the latest version of that app included
with JavaMail 1.4. It has a few fixes that might help you.
Hopefully you're not going to take credit for this with your
assignment. :-)

Java.lang.Process output stream problem

Hi, I have a program that starts a process (java.lang.Process) using the java.lang.Runtime.exec() and it attemtps to interface with it using the provieded io streams. I have both the output and error streams being handled on their own threads and I have a hashmap of output lines/command pairs that are checked so that when the process outputs certain lines to the console it feed the proper input into the process. My problem is that when I feed the input into the process it dosen't respond to it almost like the user hasn't pressed enter, The process hangs. I have tried using /n /r and permutations thereof but nothing works. The thread does read the lines from the process and does output to the process from what i can gather. Can you help me!
here is some of the code..
public void run() {
try {
     //the process's output
     InputStreamReader isrOutput = new InputStreamReader(inOutput);
     //the process's input(our output)
     PrintWriter pw = new PrintWriter(outInput);
     String line = null;
     while(true){
          if(brOutput.ready()){
               line = "";
               while(brOutput.ready())
     line+=(char)brOutput.read();
               System.out.print(line);
               if(commands.containsKey(line)){
     pw.println((String)commands.get(line));
     System.out.println((String)commands.get(line));;
} catch (IOException ioe) {
          ioe.printStackTrace();
}Thanks

Oops.. i forgot to flush my PrintWriter /blushing......... Thanks

Can java mail be used for distributed exchange server?

H,
I am trying to connect to MS Exchange Server to read my mails using Java Mail API.
I have a questions about using it with Exchange server.
We have 6-7 exchange servers in our company and different users have mailboxes on different servers. My internet mail application will be used by everybody in the company.
But while connecting to exchange server using java mail I can only cnnnect to one server and port. What happens when user mailbox is not on that server. How can I use javamail in this scenario where user mailboxes are on separate servers??
Thanks

You said that you can connect to Exchange server my you help me with this because i cant connect to Exchange server, mayby you can post me a code example? Thanks

How to delete message from the fodler of AOL account using Java mail

Hello All,
I am using Java MAil API in my application, i want to delete message from AOL account's folder,
when i set the folder as "Recently Deleted" or "Trash" , i get an exception as "folder does not exist".
when i tested , some times mail is moving into Recently Deleted folder, but not every time.
this is happening in both the interface as AOl Interface or my application.
when i use folder.close(true) after setting the flag of message as DELETED. it completely remove the message from the acount.
but i want to let the message be remained in the Recently Deleted folder. what should i do.
i dont want to remove the message completely from the account.I am using IMAP also.

You'll need to figure out what the real name of the "Recently Deleted" folder is on the AOL IMAP server
(assuming it's a real folder and not some sort of "virtual" folder), then copy the message into that folder.
See the folderlist.java demo program as a way to explore the names of all the folders on the server.

Java mail process hangs
