Java Access Helper Jar file problem

I just downloaded Java Access Helper zip file, and unzipped, and run the following command in UNIX
% java -jar jaccesshelper.jar -install
I get the following error message, and the installation stopped.
Exception in thread "main" java.lang.NumberFormatException: Empty version string
at java.lang.Package.isCompatibleWith(Package.java:206)
at jaccesshelper.main.JAccessHelperApp.checkJavaVersion(JAccessHelperApp.java:1156)
at jaccesshelper.main.JAccessHelperApp.instanceMain(JAccessHelperApp.java:159)
at JAccessHelper.main(JAccessHelper.java:39)
If I try to run the jar file, I get the same error message.
Does anyone know how I can fix this?
Thanks

sorry ab the multiple post, it was urgent for me to
know the answer.
I've JDK 1.4.2 and JAccessHelper should work with 1.3
or later
Can there be some kind of path problems?No, I doubt it. It's just some internal app failure - looks like it's trying to determine the running Java version, and is not doing a good job at it. But the failure has nothing per se to Java, it's that specific app - what are we supposed to know about that app though?

how to access this jar file
Any help or comment would be highly appreciated

Excellent question. I don't see any client-jar in your EAR file structure. So I am assuming you are writing a separate client application which will talk to the ejbs deployed as part of this EAR. You need to do the following:
Write another EAR file with the following structure:
ear:
META-INF/application.xml
util.jar
client.jar
client.jar should have a META-INF/MANIFEST.MF and that should contain Class-Path:util.jar and value for Main-Class attribute.
Now deploy this new ear to your application server and execute it using Application Client Container that comes with your app server.
If you don't want to write another EAR file, then bundle th client.jar in your original EAR file.
Points to note are:
you have to repackage util.jar again inside this ear file.
For portability reason, you should use Class-Path manifest entry in client.jar. Refer to http://java.sun.com/j2ee/verified/packaging.html and J2EE platform spec section #8.2.
Hope this helps,

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.

Can't able to access the Jar files which is kept inside the folder.

Hi,
I am using the eclipse IDE, my project folder contains the folders src, bin, .metadata, .settings
if i place the jar file in the same location of the above mentioned folder means i can able to use the Jar file in eclipse(in my project).
But i create one folder in the same location in the name of Jar or anything and all jar files are placed inside the folder,then i can't able to access the jar file in eclipse(in my project).
How i can solve this problem?

RajivGuna wrote:
..How i can solve this problem?Put Eclipse aside for the moment and learn how the SDK tools work at the level of the command line, then you will be much better placed to figure how to do it in the IDE. If you are still having problems, I suggest you ask on an [Eclipse forum|http://www.eclipse.org/forums/].

Custom Fault Policy java class is not able to access mediator.jar file

Hi,
I am trying to implement the custom java class for mediator fault handling. However when this class is invoked its not able to access the "oracle.tip.mediator.common.error.recovery.MediatorRecoveryContext" class during run time (which exists in mediator.jar). However its able to access all the other imported class files which exists in other library files.
Do we need to add mediator.jar to the weblogic classpath manually or should we place that jar file in some location in the server ?? Its currently residing in the path -- /app/oracle/product/soastg/11.1.0/SOA/soa/modules/oracle.soa.mediator_11.1.1/mediator.jar. I tried to copy the same jar into domain lib and admin lib path but there was no luck.
Any input on this will be helpful.
Thanks,
Ramesh

Hi Ramesh,
Try out the following
1) Copy mediator.jar from SOA_HOME>/soa/modules/oracle.soa.mediator_11.1.1 to <MW_HOME>//soa/modules/oracle.soa.ext_11.1.1/classes
2) Goto <MW_HOME>//soa/modules/oracle.soa.ext_11.1.1/classes and run the following command:
a. jar -xvf mediator.jar
3) Now remove the jar file, i.e., mediator.jar from classes folder.
4) Restart the server.

Srijith

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

How to create a java card library (jar file to be used in other programs)

Hi all,
I am working on JCOP and writing quite a bit of applets for the java card . Now i have lots of code that could be reusable for example sending SMS, encryption routine, etc.. So this part of the code i want to put into a utility class and create a package out of it. This utility package i must be able to import into my programs what i write.
I tried the normal way of creating the jar by renaming the CAP file of the utility class, also tried including the /javacard/* files also into the jar file as indicated by sfarmer(active forum member here). But none seems to work. I tried contacting NXP folks and they indicated that it may be possible only by way of Sharable Objects.
But some how i am not convinced why i should use Sharable object for this. So if any one can throw some light into this regard it will be immensely helpful to me and my project.

Hi,
Well the variable defined are as below
public static byte[] msgdata = new byte[255];
private static final byte[] HEADER_TEMPLATE = {
          (byte) 0x81, (byte) 0x03, (byte) 0x01, (byte) 0x21, (byte) 0x00, // Command details tag
               (byte) 0x82, (byte) 0x02, (byte) 0x81, (byte) 0x02, // Device Identities tag
               (byte) 0x8D, // Text String tag
               (byte) 0x00, // length
               (byte) 0x04, // Text String tag
the msgdata is declared public so that i can access this as a Class member in my other program doing Utilities.msgdata. But the problem is now that if i dont declare it as final then the compiler gives me the below error
"library has initialized array for non-final, non-static field Utilities, msgdata, [B, attr jc-field: tok 0, public static"
If i make it final then i cannot change it... So now i am stuck..
Any help will be highly appreciated...

How to access a jar file in EAR file?

I have a EAR file which contains EJB.jar file and util.jar file. Outside of EAR, I mean in client side, I need to reference util.jar file. How can I access it?
EAR structure is
|--+META-INF/
|--|---application.xml
|--|---manifest.mf
|--EJB.jar
|--|---+MEAT-INF/
|--|---|--- deployment descriptors...
|--|---|--- manifest.mf
|--|--- EJB classes
|--Util.jar
Util.jar must be executed in server side. If I just add Util.jar in client program's classpath, when client program is executed, serverside Util.jar is executed? Or what else I should do in the client program to reference server-side Util.jar?

Excellent question. I don't see any client-jar in your EAR file structure. So I am assuming you are writing a separate client application which will talk to the ejbs deployed as part of this EAR. You need to do the following:

Java application - build JAR file & include JCO library

Hello everyone,
I have a problem with my Java application that connects to SAP system using JCO library (sapjco.jar).
I would like to create a JAR file from my Java application but when I run the JAR file that I created I get an error that NoClassDefinitionFoundError com/sap/mw/jco/JCO at [...]
That means that the JCO and associated DLL files (sapjco.jar, librfc32.dll and sapjcorfc.dll) were not included/packed in my JAR file.
-- How can I include the JCO lib in JAR file?
-- If there is a problem with the DLL files, how can I include the JCO lib externally (dynamicly read the JCO whenever my JAR in run)?
I am using Eclipse 3.2 and Export to JAR option when I click right button on Project.
THANKS IN ADVANCE FOR HELP!!!

Hi,
The problem is that you don't have defined the libraries in the Manifest file of your jar-file. So the jar doesn't know what to use at runtime.
Add following entry to the MANIFEST.MF file:
Class-Path:/<lib_folder>/<lib1_name>.jar; /<lib_folder>/<lib2_name>.jar and so on.

Accessing a Jar file within my jar...

Hi,
I've got a JDBC Jar file that I wish to include in my Jar package, but I'm unsure how to do this...
I'm using ant to compile my code & package it up into the Jar, & I can get it to compile fine, and package everything up fine (including the JDBC jar), but when I go to run the app I get an error
(No suitable driver).
My app works fine without being Jar'ed up.
I'm guessing that I need to set the classpath to reference the JDBC jar file in my jar... but I'm unsure how to do this.
Any help would be greatly appreciated.

package what you thirdpart jar file and your jar file to one jar file..
it will run ok.
maybe the below tool can help you.
a tool named JavaJar(written by java) can compress and decompress jar,war, ear and.zip...
may download from http://www.qwerks.com/download/4114/JavaJar.zip
the tool is very verygood tool.
but the homepage(www.pivotonic.com) of JavaJar cannot be accessed.
it is funny.
good lucky.

Java Application as jar File cannot connect to SAP via JCO

Hey guys,
I wrote a test class to play a little with the java connector. Everything worked fine.
Now I want to pack my java class and the JCO classes in one jar file. I have written a manifest file with the Main-Class statement and after I start the jar file I got following exception:
Exception in thread "main" java.lang.ExceptionInInitializerError: JCO.classIniti

Can anyone help me? I don't think that I forget something during the JCO installation, because my class file worked fine and give me the correct values out of the SAP System.
Best regards,
Timo

Thanks Vladimir,
but I followed the Tutorial and copied every dll in the wright folder and set the pathes. In one of the threads someone told about a tool named dependency walker. I used this with the sapjcorfc.dll and the tool answered that the DRVADODB.DLL is not found. Can anyone send me this dll? And why worked everything fine, when I use the class? I only have problems when I use one jar file!
Thanks for any help!!

Static variables and JAR files problem

Hello All,
I am trying to get two applets to communicate.
Both are held in the same JAR file loaded from the same location. The JAR file also contains a class with some static variables which are used to comunicate between the two applets.
The applets are on separate frames in the browser and the system works fine when I don't use a JAR file but when I put the class files into a JAR file, each applet has it's own static variables (not very static).
Can anyone tell me why static variables stop working when the code is loaded from a JAR file.
Thanks in advance,
Alastair.

Ok,
I've just tried the below setup and I get the following security exception:
java.security.AccessControlException: access denied (java.util.PropertyPermission java.home read)
at java.security.AccessControlContext.checkPermission(Unknown Source)
at java.security.AccessController.checkPermission(Unknown Source)
at java.lang.SecurityManager.checkPermission(Unknown Source)

at java.lang.ClassLoader.loadClassInternal(Unknown Source)
at appSend.init(appSend.java:62)
at sun.applet.AppletPanel.run(Unknown Source)
at java.lang.Thread.run(Unknown Source)
I now have one JAR file which contains the two classes.
appSend.class & appReceive.class
and a separate details.class file
The two HTML files are in separate folders but the JAR file is still the same for both.
Classes\ -> contains the JAR file (myCode.JAR) and details.class
Sender\ -> contains the HTML file appSender.html (see below for
Applet tag)
Receiver\ -> contains the HTML file appReceiver.html (see below for
Applet tag)
appSender.html
<HTML>
<HEAD>
</HEAD>
<BODY BGCOLOR="000000">
<CENTER>
<APPLET
name = "appSender"
code = "appSend.class"
archive = "myCode.JAR"
codebase = "../Classes"
width = "500"
height = "300"
>
</APPLET>
</CENTER>
</BODY>
</HTML>
appReceiver.html
<HTML>
<HEAD>
</HEAD>
<BODY BGCOLOR="000000">
<CENTER>
<APPLET
name = "appReceiver"
code = "appReceive.class"
archive = "myCode.JAR"
codebase = "../Classes"
width = "500"
height = "300"
>
</APPLET>
</CENTER>
</BODY>
</HTML>
Is this how it should be? or have I made a mistake with the tags?
Can the ClassLoaders in either applet see the details.class file through the codebase tag?
I'm guessing from the security exception that the ClassLoader for each applet can only load classes from within the JAR file? and can't just use the codebase tag, which is not very helpful!
Thanks for your help so far.
Regards,
Alastair.
