Jar runtime problem

Hi I have a jar file which function like this
It Takes the data file from the folder and insert it into database now again next day it takes the data file(new one)
and delete old data and insert new data.
There is file handle.java which is need to be invoked to do all these functions
Now question-
1)only deploying jar file on server will work?
2)if yes How to invoke this file under jar usind java command? command because it is linux

Jar File Problem Using External Packages

I am having problems creating an Executable jar file that imports classes from my own package.
I can create an exe jar no problem without using any external packages, but when I use an external package the jar will not execute.
I am using WindowsXP, my package is in,
C:/MyClasses/Database
the class files are stored loose, not in a jar file
I have tried altering the class-path in the manifest file, but to no joy - I may have not changed the classpath correctly!
Please help
Magic

This is a mine field of "correct programming style."
External jars, if very general, could be placed in the directory jre/lib/ext.
In some cases you can unzip the external jars and add them to your own jar.
The manifest.mf migth be looked into, and of course you need to communicate your patching!
As you remarked, it might be a problem of class path usage.
For that the jar tool documentation might explain it better than I.

Have CS5 and after installing yosemite is asking to install Java SE6 Runtime, problem is Java has a ton of version 6 and none for Mac, why hasnt adobe provide the right version download?

Adobe needs to get their act together, be specific as to what version of Java SE6 Runtime is needed to open CS5 (InDesing, Illustrator, etc.)and if possible offer a direct download, since Oracle has a ton of version of SE6 and none of them for Mac specific platform. This short sight on behalf of Adobe and carelessness on behalf of apple is the kind of garbage, this companies will never get!

I'm pretty sure this post has the link in it...
Dreamweaver and Java SE 6 Runtime problem on MAC Mountain Lion OSX
If not, do a search of the DW forum for Java SE 6, there has been a lot of discussion about it and the download link for it is floating around here somewhere.

Hi,
I'm on a mac 10.3 and have no intentions of upgrading. When I try to start some demo's I get a lot of different errors, all as far as I can tell related to the JRE. I installed everything from the apple website:
Java webstart 2.3.0 (modified the May 2007)
Applet Launcher 1.4 (modified the May 2007)
Here's 2 of them: I give the info I get from the console:

Execute an external java program with Runtime, problem with classpath

Hi,
I m calling an external java program by the command:
Runtime.getRuntime().exec("java -classpath \"library/*\" org.mypackage.TestMainProgram param1 c:/input/files c:/output/files");All my classes are stored in the relative directory "library", and it contains ONLY .jar files. However, I keep getting errors like:
"java.lang.NoClassDefFoundError: library/antlr/jarCaused by: java.lang.ClassNotFoundException: library.antlr.jar at java.net.URLClassLoader$1.run(URLClassLoader.java:200) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at java.lang.ClassLoader.loadClass(ClassLoader.java:307) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:252) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:320)Could not find the main class: library/antlr.jar. Program will exit.Exception in thread "main" where "antlr.jar" is a jar file in "library". It is there but still the program keeps complaining it cannot be found. The problem applies to any jars in "library", ie.., if i have "mylib.jar" then it will complain "NoClassDefFoundError: library/mylib/jar".
Could anyone give some pointers please?
Many thanks!

Edited by: 836590 on 14-Feb-2011 09:03First, if you run from the command line
java -classpath "library/*" org.mypackage.TestMainProgram param1 c:/input/files c:/output/filesfrom the parent directory of library, does it work?
Despite what I said to Kayaman about Runtime.exec not expanding the asterisk, it looks like that's what's happening, so that you're getting
java -claspath library/aaaa_something_before_antlr.jar library/antlr.jar library/bbb.jar library/ccc.jar org.mypackage.TestMainProgram param1 c:/input/files c:/output/filesThat is, it *is* expanding the asterisk to a list of files in the directory, and the first one is being taken as the classpath, and the second one--library/antlr.jar is being taken as the class to execute. I'm certain this doesn't happen on Linux, so it must be a Windows thing.
Two suggestions:
1) Try single quotes instead of double.
2) Try the exec that takes an array
Runtime.getRuntime().exec(new String[] {"java", "-classpath", "'library/*'", "org.mypackage.TestMainProgram", "param1", "c:/input/files", "c:/output/files");Edited by: jverd on Feb 14, 2011 9:41 AM

Deployment Plan / weblogic-ejb-jar.xml: Problem

Hello,
I am trying to use a deployment plan to override the principal name in the weblogic-ejb-jar.xml.
The deployment-plan looks like this (showing only the important sections)
<variable-definition>
<variable>
<name>SecurityRoleAssignment_ejbRole_PrincipalNames_1</name>
<value>MY PRINCIPAL 1</value>
</variable>
</variable-definition>
<variable-assignment>
<name>SecurityRoleAssignment_ejbRole_PrincipalNames_1</name>
<xpath>/weblogic-ejb-jar/security-role-assignment/[role-name="View-Role"]/externally-defined</xpath>
<operation>replace</operation>
</variable-assignment>
The security-role assignment in the weblogic-ejb-jar.xml looks like this:
<security-role-assignment>
<role-name>View-Role</role-name>
<externally-defined/>
</security-role-assignment>
I 've tried to override the element-value of <externally-defined> (a valid tag in the weblogic-ejb-jar.xml ) with help of a deployment-plan.
When trying to deploy my application (which is organised in the directory-structure: inst_dir/APP inst_dir/PLAN
the following error occurs:
VALIDATION PROBLEMS WERE FOUND problem: cvc-complex-type.2.4a: Expected element 'principal-name@http://www.bea.com/ns/weblogic/10.0' instead of 'externally-defined@http://www.bea.com/ns/weblogic/10.0' here in element security-role-assignment@http://www.bea.com/ns/weblogic/10.0:
This has surprised me, as externally-defined is (according to the documentation) a valid tag.
I have tried to replace <externally-defined> with an empty <principal-name> tag (which works fine when deploying the application), but causes a security exception, when trying to use the EJB.
Has anybody an idea if there is a workaround for this problem?
IMHO the Validatio Problem is not justified at this place then why should an otherwise valid weblogic-ejb-jar.xml (when not using a deployment-plan) suddenly become invalid when a deployment plan is used?
Thanx a lot in advance!

This all seems very strange.

Dreamweaver and Java SE 6 Runtime problem on MAC Mountain Lion OSX

I have a problem with dreamweaver. I really love dreamweaver for building web pages and have used it for years with a PC. I recently switched from a PC to a MAC but I find that when I open the Dreamweaver app for the first time I get a prompt that says something like "You must download Java SE 6 runtime, would you like to install it now?" I click yes, and the download fails. I called Apple about it, they said the software resides on Oracle's Java web site, and its out of their control. I go to the Oracle Java web site it says "Apple supplies their version of Java SE 6 runtime and there's no way to download it from the Java.com site. All this means is that YOUR software does not work on my MAC because these two companies can't agree on who suppies this software.
What I need to know is HOW DO I GET DREAMWEAVER TO WORK? How do I get around this crazy *** catch 22 situation? And why doesn't your software recognize Java SE 7 runtime?

I'm in the same boat with you. I recently used Time Machine to backup my profile and then wiped my entire drive and installed Mountain Lion. After importing all of my data with the Migration Assitant, Dreamweaver will NOT open.
SnakEyez02, Oracle's website does NOT have the dowload. The link you posted is to version 7. We've been down this road already. Martiantime is correct, neither Apple nor Oracle are providing Java SE 6, but Dreamweaver is crying to have it installed.
So, Adobe, how do we get out of the hole that we did not dig?

Jacob.jar and Webutil.jar singing problem(URGENT)

I read the instructions 'Configuring the webutil' and I found that there is not a reference in the file 'signer.properties' which is referenced in the on-line help of Forms Developer (step 4).
The problem is that when i try to sign the 2 jar files 'frmwebutil , jacob'
using this command
E:\oracle\ora92\forms90\WEBUTIL>SIGN_WEBUTIL.BAT e:\oracle\ora92\forms90\java\jacob.jar
after this command a essage appears:
Genrating self signing certificate for key=webutil2...
Keytool error :java .lang.execption:key pair not genrated ,alias <webutil2> already exists
there were wanings or error while genrating a self singing certifciate . please review them.

'jarsigner' is not recognized as an internal or external command.
Is there a chance that the cause of this problem is that there is not the file 'signer.properties'?
What can I do ?

.jar (Java) Problem - Nokia 5800 XM

I am having a problem with installing .jar (java) games/apps to my phone.
What happens is that it starts installing and then "hangs" at around 75% and the phone doesn't do anything for about 30 secs, the phones seems "hang". I cant run any .jar file because of that. Is this a known problem ? What can i do to fix this ?.
I tried copying the files to the phone and install from there but the same problem occurs.
I have the certification set to ALL.
I get no error just the "hang" problem.
Can anyone help me? getting frustrated!

Thank you

My settings with air 3.3:

        <softKeyboardBehavior>none</softKeyboardBehavior>
    </initialWindow>
It only displays a white screen with a small gray square (1/5 of the screen size - top left).
A scrollbar is visible if you drag the screen and the sound is playing...
I tried this settings:
<aspectRatio>portrait</aspectRatio>
        <renderMode>gpu</renderMode>
          <autoOrients>true</autoOrients>
        <fullScreen>true</fullScreen>
        <visible>true</visible>
        <softKeyboardBehavior>none</softKeyboardBehavior>
    </initialWindow>
It won't work...
Edit:
I also tested the new sdk http://www.adobe.com/products/air/sdk/ with gpu mode.
iPhone works fine but the iPad version always crashes.
The app opened up but if I try to load a level created with box2d the app always closes (crashs).
I think that is a gpu ram issue?
Is this a iPad issue or air?
Edit 2:
I changed the creationcomplete event to viewactivate. The transition now looks really worse but the levels are loading.
I also deleted all the elements before changing the view (removeElement and removeChild).
The third step I made was to use weak eventListener obj.addEventListener("event, function, false,0,true);
I think that iOS systems have the problem of less gpu ram than android devices ...

Possible Java Runtime problem

I am an amatuer at best.
I am receiving an error when trying to access any part of windows explorer now. I can't open folders at all.
Included in picture format is the error.
I'm running XP Home edition service pack 2
more than enough ram/HD
I recently un-installed AND re-installed java (from java.com). When java isn't installed - windows explorer works just fine.
This problem is recent (last week or so) To my knowledge ZERO applications are been installed or modified. This computer is solely used for archiving pictures/video and web surfing (with the occasional video playback via VLC media player.
Please let me know if you have any suggestions on how to combat this problem without having to re-install windows.
If you need more information: please ask.

Jar file problem , please help

Hi guys , i am not sure if i am in the right place to have this post in so i'll give it a try
i know my explanation might be a shot in the dark but i'll try my best
i have made a program using eclips , to send emails using my email , on certain conditions
so when that codition happenes on some class in my program
this class will call the email class and send an email to someone
now the problem is not in the program , because as along as this program is in eclips and i run the program in eclips , everything goes fine , No errors what so ever
but , if i make jar file , using eclips "export"
once i run the program , the program would run , but once the same condition that ihave specified previously happenes , the current class never calls the email class , and no emails would be sent
i am very confused wether
1) it throws a class not found for some wierd reason
2) or the external library that i used to send emails , is not exported
i tried to check the CLASSPATH file and i think everything seems to be fine , so i dont know what the problem is
so in short
if the program is in eclips , every thign goes fine
if the program is a jar file , then it would work fine but once it needs to send an email , it never does and i can still work on the program , but no emails will be sent
thanks please some one help me out with this

for more information here is the senario
because i see that you guys are some how lost because i am not providing enough information
so this is a detailed info of the problem
i have 3 classes
1) mybankmain (jframe)
2) mybankbody (all labels and buttons and events included here)
now: within some events in my program ,
it calls a class called.....
3) myEmail
this class imports two things that are comming from an external jar file , so in short , if the external jar file is not available the program would complain
i run this on windows xp (SP2)
now: if this program runs on eclips , it would do everything it is supposed to do and all kind of calculations will be done and emails will be sent on the conditions that i have specified within the program
if i make a jar file on windows , and i run the jar file , the file would work , all functionalities will work
EXCEPT: sending an email
- either my class is not found
- or external jar file is not found which causes my class not to be able to perform its tasks
i did only one test
which is that i switched the main and i made myEmail as a main and i tried to export the jar file
Result: jar file doesnt work
the way i view whatever inside my jar file , i use Winrar and it would view everythign in the jar file and i see that all my classes are included there
if i open my CLASSPATH , i see that there is a pointer to the external jar file
if i open my manifest : i DO NOT see the exrernal jar file in there but i do see that its pointing to my main class
class main : mybankmain
and there is only the version and signiture
i hope all these additional details would help in determining the problem that ihave been trying to solve for 2 weeks now

Jar signing problem? (continue with HOST PJC)

<1> I've sign jar-file on Oracle9iAS server.
<2> First form (with bean from that jar-file) loading asked me for "Granting", and after it runs without problem, bean is worked prefectly.
<3> Second form loading shows me nothing, just explorer hanging.
I've check JInitiator (1.3.1.9) Control Panel, Certificates tab... there is now any records. Maybe there is problem.
(I also have(installed) Sun JSDK 1.4.1_01)
Java Console also doesn't show any errors.
Again form with bean doesn't loading at the second time.
What is the problem ?
Thank You

Have you read the paper on Signing JAR files for JInitiator 1.3 - it details some changes that you'd be advised to make to your HTML template and the HOST bean code to get around this problem..

JAR File problems

Hello,
I have a jar file with some code I wrote that accesses a jar file from a 3rd party. I want to include the 3rd party jar files inside my jar file. So I basially have a jar file with my code (unjarred) and include the 3rd party jar files in my jar. In my MANIFEST.MF file I have properly set the Main-Class property correctly, as well as the Class-Path property. I have set my Class-Path value to 3rdparty.jar which is the jar file at the root directory of my jar. When I run my jar file I get a NoClassDefFoundError saying the 3rdparty jar file is not found. I have added a new line at the end of my MANIFEST.MF file, and am actually using ant to create my MANIFEST.MF file. When I unjar my file everything looks correct. What is the problem here? I have made sure the 3rd party classes that my code access are in the jar. What could I be doing wrong??

Standard Java does not support placing a jar file within another jar.
You can search for 3rd-party alternatives, ow write your own custom classloader.

Updating to signed JARs causes problems for older Java versions?

Bear with me on this one -- not a Java developer, but an end user of Java products looking for a little clarification.
We use a product which delivers a Java application via JAR file / web to end users (GlobalScape's EFT server). With the recent release of Java 7 Update 51, users have been running into issues running these JAR files as they are not properly "signed". We're working with the vendor to get updated signed JAR files in place, but they've warned us that these new JAR files will cause errors (or maybe not work at all) on folks who aren't running Java 7 Update 51.
Trying to wrap my head around why that might be. Best theory I can come up with from perusing threads here along with the Java team blogs is that the new security attributes used in the updated JAR files aren't "trusted" by older versions of Java (prior to Update 51?).
We're pushing our vendor for clarification, but curious if someone here could help explain.
Thanks!

I suspect the problem with 'new JAR files will cause errors' is mainly because the vendor keeps enhancing their product, and may not any more support older JREs, or the new jars are no more compatible For example, we build our product on JDK 1.5 ... as some users out there must use that one because the 'newer and better' release does not work for them.
But so far, we have not seen any problems running the 'JRE 7 Compliant' applications on older releases ... provided you can make your application run on latest JRE 7.
In most cases, one can simply remove the previous signature, add (now required) attributes, and sign the same jar again.
But I have yet to find a vendor that would simply add attributes to some older release and re-sign those. Perhaps they can't repeat the build / QA cycle, and would not 'trust' the re-signed jars.
Our curse are signed Cryptographic Provider jars.
Those must be signed by certificates rooted by Sun/Oracle, and adding attributes invalidates that signature - we can re-sign them, but then they won't work. In our case, we are stuck with 5+ year old Bouncy Castle jars, and it does not help us that their 'current' jars are signed with attributes - they are completely incompatible..
IMHO, Oracle failed to think this all thru - or does not care.
