Problems with CR used by a Java app when converting from WebSphere v5 to v6

Background: I have been assigned support of an old Java app, currently running just fine in a WebSphere v5 environment. It uses CR to produce 4 reports. Running the app in the WebSphere 6 environment, 2 work and 2 don't. (!?!?)
I don't know what version of CR the reports were originally designed in - nor do the people who produced them 6 years ago. I have tried installing (and uninstalling) various versions of CR on my PC (v7, v8, v8.5, v9, v10, v11) to see if I can find one that would work with the .RPT files. None do. Either I get a warning that the report file is in an old format and saving it will prevent its use by the older version - whatever that may be...; or it opens the report, but when I click on the Database tab on the menu bar, CR locks up my machine.
It has been decided by my management that it would be best to just upgrade to CR vXI and continue from there. The XI 'developers edition' is what I am currently running. However, when I open the .RPT file (one of the ones that work), it takes about 5 minutes; then when I click on the Database menu item, it locks-up my pc.
I have other experience using (back-versions of) CR, but have never run into anything like this. Has anyone had any experience with upgrading reports designed for Java to the vXI? Can you provide me with any information, hints, suggestions about how I might proceed?
Thank you, in advance, for any assistance you might be able to render. Regards,
Jeff Emslie.

Hi, Jadie.
Thanks for the quick response. It may be the original report definition was designed pointing to SQL/Server v7, then was being overriden by the Java code to SQL v2k - which we are about to convert away from... I have no experience integrating CR into a Java app. I don't know how the data source specification works with Java. That is why the first thing I'm trying to do is to look at the Database connection: to see how its done.
As for the version it was originally written in; I don't know what it is. No one here knows. I have tried every (old) version of CR we have in the shop (list above). None seem to work correctly with these .RPT files. Do you know of a way to determine the CR version of an unknown .RPT file?
Thanks,
Jeff.

Pdf file transfer using ftp in java

Problem running my Java apps in my LG phone. Please help!

Hi all!!
I am quite new to the world of J2me, altough I've been coding Java for quite a few years now.
Recently I bought a LG u 8120 phone with Java-support so I decided it was time to step into the mobile Java-world.
Now I have written my first small app, a simple timer application which my phone (strangely enough) does not already have.
So what happens is this : I create my app on my PC and package it with the WTK into a jar -file and a jad-file which i transfer to the phone.
After this I can see the name of my app in the list of available programs in the phone. But when I try to run it: Nothing. The Java logo shows up for a few seconds and then I am tossed back to the menu.
I have thought of the following as possible problems:
1. the 8120 does not support MIDP2.0
2. I am doing something wrong transfering the files
3. I have missed out on one or several necessary steps in the process
Anyone who have developed Java apps for LG phones who can give me some hints?
I've used the Sun J2ME Wireless Toolkit 2.2 with MIDP2.0 and CLDC1.1 .
The apps works fine in the emulator. The problem starts when I want to run it in the phone. The phone I've tried is an LG u8120. LG apparently does not want to make life easy for its customers, so there is no support for transfering Java apps in the vendor-supplied software. I suppose that's because they want you to only download stuff from their site. However, after surfing around on some discussion forums for a while I found a program called G-thing which can be used to upload Java apps to LG-phones via USB.
Any help is very appreciated!
Thanks,
Sarah

Thanks,
I have tried this and ruled out some of the possible causes.
When I added some more exception handling, I could see that a "java.lang.IllegalArguenException" is thrown.
When I ran the AudioDemo package that came with WTK2.2 I noticed that the examples that uses WAV-files do not work while the rest works fine.
My new theory is now that the u8120 does not support the WAV-format, so I will try with an mp3 instead and see what happens.
Anyone who knows if LG-phones support WAV-format?

Q: FTP through java?

Hello,
I am trying to do an FTP through java. Does anybody know how I can spawn an FTP process and send ftp commands to it from my java program?
I am on a Solaris system BTW.
Thankyou in advance...

I see you haven't assigned any duke dollars to your question. Let me tell you how does the Duke Dollar system work. Observe the following example...
I know the answer.
My rates are as follows:
zero duke dollars - vague hint
one to five duke dollars - +definite answer
six to ten duke dollars - +full file/package name
ten to fiteen duke dollars - +URL information
more than fifteen duke dollars - +full URL with download information
Pick your choice and select the appropriate answer:
0 - There are premade classes that allow you to use FTP in Java.
1 - 5 IBM have created a package that will allow you to do things that you desire.
6-10 You should be looking for the FTP Beans Suite by IBM It comprises of two beans - the FTPProtocol bean and the FTPUI bean, both are very useful, especially in your situation.
11-15 You can find this suite at http://www.alphaworks.ibm.com
16+ go here http://www.alphaworks.ibm.com/ab.nsf/bean/FTP to add file transfer functions to your applications... without writing a line of code.

How do I run multiple java apps in one JVM to reduce memory use?

Hi all,
I saw an article either on the web or in a magazine not too long ago about how to "detect" if the app is already running, and if so, it hands off the new instance to the already running JVM, which then creates a thread to run the Java app in. As it turns out, my app will be used in an ASP environment, through Citrix. We may have as many as 50 to 100 users running the same app, each with their own unique user ID, but all using the same one server to run it on. Each instance eats up 25MB of memory right now. So the question is if anybody knows of a URL or an app like this that can handle the process of running the same (or even different Java) apps in one JVM as separate threads, instead of requring several instances of the JVM to run? I know this article presented a fully working example, and I believe I know enough to do it but I wanted ot use the article as a reference to make sure it is done right. I know that each app basically would use the same one "launcher" program that would on first launch "listen" to a port, as well as send a message through the port to see if an existing launcher was running. If it does, it hands off the Java app to be run to the existing luancher application and shuts down the 2nd launching app. By using this method, the JVM eats up its normal memory, but each Java app only consumes its necessary memory as well and doesn't use up more JVM instance memory.
Thanks.

What path to use to access network files from Java app running on Mac

I have a Java app running on a Mac with OS X that I'm using to check for files that exists on Windows servers within our network.
Using a path like /Volumes/<Share>/ works because I've already connected to the drive using Finder. If I try to use a fully qualify the path with "smb://<Server>/<Share>" then my app doesn't see anything. Is there any way that I can get Java to connect to a directory without first having mapped or made the connection via some external tool like Finder?
Here's the code I'm testing with:
package FileImports;
import java.io.File;
import java.util.Arrays;
public class Dir {
static int indentLevel = -1;
static void listPath(File path) {
File files[];
indentLevel++;
files = path.listFiles();
if (!(files == null)){
Arrays.sort(files);
for (int i = 0, n = files.length; i < n; i++) {
for (int indent = 0; indent < indentLevel; indent++) {
System.out.print(" ");
System.out.println(files.toString());
if (files[i].isDirectory()) {
listPath(files[i]);
indentLevel--;
} else System.out.println("Directory not accessible!");
public static void main(String args[]) {
// this path works where <share> = the directory where my files exist.
listPath(new File("/Volumes/<share>"));
// this path returns a null result in files
// listPath(new File("smb://<Server>/<Share>/"));
Thanks,
Alex

Thanks for the response. I'll have to dig a little deeper into JCIFS. It looks like it would work great windows to windows. I haven't been able to find in the documentation where it would work on OS X without having to mount the targeted file system first. Has anyone had success creating a connection to a windows file system from OS X with JCIFS?Since jCIFS is written in pure Java and implements the entire SMB/CIFS protocoll on it's own it doesn't require any support from the OS (apart from a normal JVM runnig). Thus it should work exactly the same in OS X and Windows (and Linux and Solaris and ...).

Java Errors when using my Java App via Remote Desktop

I have a Java App that runs fine if I invoke it and run it on a windows xp machine "x".
If I remote desktop connect to machine "x" from another windows machine "y"
I get the errors and the Java App is not displayed correctly. It becomes unusable.
While remotely connected if I terminate the Java App and restart it the App
will run just fine and not generate any errors.
Specifically the steps are:
Open a cygwin shell.
invoke the app...java -jar xxx.jar
use the app on the machine, works fine without any exceptions.
Leave the app running and go home...eat dinner...then
VPN into the office
Startup Windows Remote Desktop to the pc running the app.
Start to use the app. Now the exception occur as I click on buttons/enter data into fields.
Then I terminate the App.
Then I restart the app... java -jar xxx.jar
It works fine without exceptions.
This app was developed using NetBeans 6.5
The errors are:

Java.lang.NoSuchMethodError: getSocket using JavaMail inside JBoss

Hi,
i built a library to easily send emails with JavaMail, via SMTP. When i use my lib in a stand-alone java application, it works fine, but when i need to use it inside my web application, deployed on JBoss AS, i get the following error:
Servlet.service() for servlet action threw exception
java.lang.NoSuchMethodError: getSocket
     at com.sun.mail.smtp.SMTPTransport.openServer(SMTPTransport.java:1250)
     at com.sun.mail.smtp.SMTPTransport.protocolConnect(SMTPTransport.java:370)
     at javax.mail.Service.connect(Service.java:233)
     at it.compit.mail.helper.send.SMTPSender.send(SMTPSender.java:39) where it.compit.mail.helper.send.SMTPSender.send is the method i use to send email in my lib. SMTPSender.java at line 39 is
SMTPTransport tr = (SMTPTransport) session.getTransport("smtp"); I don't want to use SessionBean to send email from JBoss AS. I did not include mail.jar in server/default/lib dir because JBoss has got a built-in implementation of JavaMail. Using javamail debugging, i've noticed that javamail inside my JBoss is "JavaMail version 1.3.1", while i used version 1.4ea to build my lib.
So, any ideas to solve my problem?
Thanks in advance.

Hi bshannon,
i looked for other javamail libs in my JBoss dir: found nothing but the only mail.jar located in server/default/lib/ (provided by default installation). I tried to specify the classpath into mail-service.xml without success.
I also noticed that when JBoss starts, logs print "DEBUG: JavaMail version 1.3.1 " while the MANIFEST.MF inside my mail.jar contains "Implementation-Version: 1.4".
My JBoss version is 4.0.4 GA. Any idea?!?

Sql_trace does not work for Java app using Oracle JDBC thin driver

Hi,
I'm using Oracle 8.1.7. I enabled sql trace at instance level by setting sql_trace and timed_statistics to true in init.ora. I restarted the db instance. I wrote a stand-alone java application which used Oracle JDBC thin driver(classes12.zip) to make a connection to my db instance, do some select statements, and close the connection. There were no trace files generated in the folder specified by udump_dest variable. However, if I used sqlplus or dba studio, I saw trace files generated. Has anyone got Oracle sql trace work for JDBC calls from java apps.
Thanks in advance!

Can I create a java app for my palm zire 71 that uses floating point calc

I am an eclipse user that is looking at studio creator 2 and was wondering if I could create a java app for my palm zire 71. I have read alot about no floating point support in midp... is that true for java on the palm? If so, how does one calculate with floats and doubles to do sqrt functions etc?
Thanks in advance for your time

I looked at netbeans and it does not support floating points in midlets. Not good for palm app if no floating point ability. J2ME supports floating point but in netbeans... is uses midlets and there are no floating points. Now what does one do? Not that dreaded C++
THanks in advance

Make java app. NOT use ".bat","sh","exe"-jar get params from manifest!!

Right now a jar file's manifest can have a "main-class" which makes the jar truly executable - you can double-click it. The problem is, if you need environment variables, there is no way to pass them in to your main-class' "args."
So why don't we make it so when the jar's manifest is read, that in addition to "main-class" you can have "main-args"?
That would mean everyone would no longer need to bundle java apps with ".exe" or ".bat" or ".sh" files!!! We could have truly Java applications, that are executables!!!
Just package them in a jar, have a main class and the args for it!!
what does everyone think?

Unfortunatly, it won't happen.....
Sun has been pushing property files ever since they disabled getEnv. You are probably better off designing some sort of Runtime.exec("echo $VARIABLE") or such to catch the environment variables during init. Or you could just start using property files like sun would want.

Trying to Access Website using SSL running JAVA from inside ORACLE DB

Hi,
I am trying to access website using SSL and running JAVA code from inside Oracle 10g DB server using SSL and Java. I have loaded my java code into Oracle data base. My problem is when I am running same code from outside the DB it is running perfectly fine but when the same code is loaded into DB and trying to run from DB under these environment I am using for running my code:-

Thanks a lot in advance.

0- the fact the ISA server logs an 'anonymous' seems logical, since it answers by HTTP 407. I will say it's even a "good log" :) but I had preferred a good old "security exception" but it's not the case..
1- The code for checking the properties (your debugging) should be placed BEFORE trying to connect to the url if you want to see what's happening
2- The 'normal' way to set the proxy is to set the following properties
System.setProperty("http.proxySet","true"); // and NOT https.proxyset as ejp said
System.setProperty("http.proxyHost","123.456.789.123");
System.setProperty("http.proxyPort","80");
3- what's the behavior if you change 123.456.789.123 by the real name (hostname) of the server ?
4- You can try setting up the proxy in the java control panel instead of in your code (easy to do under Windows, you look for the networking settings, and you find the proxy settings for http/https there. Otherwise look for all files called net.properties and edit them).
5- to help debbuging, we can rely on several methods of Authenticator :
protected PasswordAuthentication getPasswordAuthentication() {
System.err.println(".\tgetRequestingHost: " + getRequestingHost());
System.err.println("..\tgetRequestingSite: " + getRequestingSite());
System.err.println("...\tgetRequestingPort: " + getRequestingPort());
System.err.println("....\tgetRequestingProtocol: " + getRequestingProtocol());
System.err.println(".....\tgetRequestingPrompt: " + getRequestingPrompt());
System.err.println("......\tgetRequestingScheme: " + getRequestingScheme());
return new PasswordAuthentication("<USERNAME>",new String("<USER_PASSWORD>").toCharArray());
Try all this and let us see the output messages.
Please remember to give some 'duke stars' if it helped resolving the problem ;)

Windows Macro Engine for use with Java Apps

Does anyone know of a macro engine that can be used under windows for interaction with a Java app? None of the ones I've tried will work with Java Apps. Work great with everything else I've tried, just not Java apps.
Will

What exactly is a macro engine? What do you want it to do? Do you want to add scripting to your application? Or do you want to script third party applications, that don't support it themselves?

Use FTP inside java app.
