Can't create .jar file?
Am trying to create a .jar file, but without any luck? My classpath is set like this:
C:\j2sdk1.4.2\bin;
And am trying like this:
cd C:\Documents and Settings\aslan1\Skrivebord\retroguard-v1.1\retroguard-v1.1\Regnskab1.5.1\
jar cvf Aslan.jar *.class *.png *.gif *.jpg hsqldb.jar
I get an error like that the command 'jar' is not recognized. What am I doing wrong?
The classpath is for finding compiled class files.
For executing programs, you want to set the %PATH% environment variable.
This actually has nothing to do with java; it's a general OS issue.
Anyway the value you set your classpath to (C:\j2sdk1.4.2\bin) is what your path should be. That value doesn't really make sense for a classpath anyway.

When re-installing JRE 1.2.2 I get an error "can't create JAR file"
When I uninstalled Java Runtime 1.2.2 and reinstalling, at the end of the installation I get an error:

Only trouble is I've got 14 GB open and the uncrunch.log file isn't even created.
Any suggestions or help would be greatly appreciated!

Problem while creating JAR file for my swing application
Hi...
Using my swings application I am trying to Run different software�s .
My program is Running fine from command prompt. If I create JAR file
It is giving error like �Failed to load Main-Class manifest attribute from .jar�
Can anybody help me to creating JAR file
Thanks in advance
Cheers
Mallikhi,
User following command
jar-cmf textfile_name.txt Jarfile_name *
here you have to make manifest file
and making jar file you have reach there by command promt
and manifest file have some constraint also as well as format
format are

How to create jar files from my code?
Hi, I�m a rookie programmer and i need to create jar files in my application code. Which classes do i need to use?
Can anybody give me an example?
Thanx in advanceThanx Uwe. You�re right, i�m only trying to create jar
files (and extract files from a jar file) I will try
what you told me. Anyway, I have some doubts about how
to use those classes.Can you give me any example?
Thanx again!To create jar files use the class JarOutputStream.
Add a ZipEntry for each entry in the jar file.
To read jar files use the class JarInputStream and get all JarEntry.
It should be straight forward.

Can I place jar files inside ejb-jar.jar?
Hi,
I'm reading about the packaging rules for creating an ejb-jar.jar file, and I'm wondering whether it's possible to include a jar file (containing helper classes) inside of the ejb-jar file. A "lib" dir (for containing such helper jars) doesn't seem to be part of the ejb-jar file format.
The EJB 3 spec has this to say (Ch 20, "Enterprise JavaBeans 3.0, Final Release):
"The ejb-jar file must also contain, either by inclusion or by reference, the class files for all the classes and interfaces that each enterprise bean class and the home interfaces, component interfaces, and/or web service endpoints depend on, except Java EE and J2SE classes. This includes their superclasses and superinterfaces, dependent classes, and the classes and interfaces used as method parameters, results, and exceptions"
Now, it seems that the root of the the ejb-jar file contains all the classes (in the appropriate Java package layout). But what about including JAR files? The ejb-jar spec seems to have nothing to say about a "lib" dir that can contain jars (as a WAR file can).
Summary of questions:
1) Can an ejb-jar file contain a jar file? If so, how/where?
2) Can the ejb-jar file's META-INF/MANIFEST.MF file contain a reference to a JAR file?
I'm not considering correct design at the point... I'd just like to know if these 2 scenarios are possible.
Thank you!
kamuifxYes, I have an ear file..................
I have an EAR file; inside the EAR I have a WAR file (web module) and an EJB-jar file (EJB module).......... the EJB need some classes placed in a jar file (a helper .jar or an util .jar)...........
my question is: How can I use the classes of the .jar files in te EJB??????
thanks -
Creating JAR files programmatically
I am trying to create JAR files programmatically using the java.util.zip and java.util.jar APIs. I am starting with just a set of directories containing .class files. I can seem to make the JAR but if I try to use any of the classes in it they don't work. But, if I unzip the JAR using WinZip, the classes are usable. So I am somehow building the JAR file incorrectly. Does anyone have any ideas or suggestions? The code is pretty long so I won't post it yet but I can send it to you if you'd like to see it. Contact by email if you'd like to see the code. Thanks.
What paths are you encoding? Here are a couple of rules:
1 - All paths are '/' separated, and do not begin with a '/'.
2 - All paths are relative (see 1) and contain the exact package name of the class, plus the class.
E.G., the class java.lang.Object would look like this in your jar:
java/lang/Object.classNothing more or less. -
Need inputs for creating Jar file
Hi All,
I am doing the scenario as file to mail. so here i am using java mappings for sending the file in mail attachment.
as i can see in my system there are already one imported archive exists with name called "java_mappings".
in that i can find 10 to 12 mapings which are used for different interface.
i have tried to export the imported archive to my local system and created the project with same in NWDS.
but here i can not find jar file.
can anyone suggest how can i get jar file for already exist the imported archive.
second option is if i want to create new mappings then how can i get the Jar file.
thanks,
BhaskarHi Bhaskar,
Jar file is an archive which consists of all class files needed by Java mapping. If you have a folder named Java_mapping and you guess that it is being used in different interfaces, then it should have the class files in it... may be the source code is missing...
I will suggest you to export it into your local machine and extract using winzip.. then you might see some file with .class extesnion. Try a tool like frontendplus which will make java code from java class file to get there code..
Now if you are trying to make one for your requirement i would suggest to read the stefan grube blog..

Also note that the java mapping is just a jar file which has:
1. the com.sap.xpi.ib.mapping.lib.jar (PI7.1) or aii_map_api.jar (PI7.0 or XI3.0) file
2. You java code class file.

I can`t open jar files though my java version is updated
Hello everybody, I`m using Macbook Pro 13` with Lion on it.
As it says in the title, I can`t open jar files though, my java version is updated.
It says, I shuld check the console.
Right now, my java version is, "1.7.0_15", and i`m trying to open a jar file created 3 days ago, by some developer.
Although, if im trying to open jar file created 1 year ago, it doe`s open.
Why is that? and, How can i fix it?
Thanks.Franeo wrote:

With Java 6 and prior, you had to enable logging first before you could view error messages in Console. I am guessing that you need to check the Java Control Panel to see if logging is turned on. -
How can I make .jar files for applications?
My jar program creates jar files but won't open the program when I double click them. I use the command:
jar cvf *.jar filenames
The jar file is created but won't execute. Can anyone tell me what i am doing wrong?
Thanks
JibyHello !
Well, I had the same problem a week or two ago !
First, in your *.java, don't use any package...I mean, don't do a package of your program (I guess there is a way to make it work with, but it would need a little bit more work...).
Then, with the jar tools, use the command
-jar cf jar_that_you_want_to_create.jar class-that_you_include_in_your_jar.class
With that, a jar will be created, and when you will try to "run" it, it will say that it can not find the main class...
You need a Manifest !
Create a text file MyManifest.text, and write that in your text file :
Main-Class: classname
follow the same as i wrote above. leave a blank after colon and a blank line after the first line like above.
then, well, use tha jar tool again:
-jar umf MyManifest.txt jar-file-you-created.jar
To "run" it, double click on it, or use the java tool:
java -jar jar_you_created.jar
Thanks to Phani, who helped me with that !!

Crystal Server 2013: How to troubleshoot "Can not create temp file---- Error code:-2147215357"
We have a Java7 web app, which generate PDF report by calling Crystal Server 2013 SP4.
The app is being deployed on many different servers. We sometimes got the error below when generating report:
com.crystaldecisions.sdk.occa.report.lib.ReportSDKException: Can not create temp file---- Error code:-2147215357 [CRSDK00000615] Error code name:internal
at com.crystaldecisions.sdk.occa.report.application.PrintOutputController.controllerExportInternal(PrintOutputController.java:280)
at com.crystaldecisions.sdk.occa.report.application.PrintOutputController.export(PrintOutputController.java:152)
at com.crystaldecisions.sdk.occa.report.application.PrintOutputController.export(PrintOutputController.java:130)
at com.crystaldecisions.sdk.occa.report.application.PrintOutputController.export(PrintOutputController.java:113)
Problem is, this seems to be a pretty generic exception. It could be caused by many different reasons.
e.g. network connection problem, wrong DB login, wrong folder path, lack of folder access right, etc.
Each time we could only guess what's wrong.
We are running into it again, and this time everything seems correctly configured so far.
We wonder if there are more info we can get to troubleshoot? For example, any log file of Crystal Server we should look into? Or does Crystal Server has debug mode which prints more details to tell us what goes wrong?Prithviraj Shekhawat wrote:
Hi Henry,
I believe you are using RAS SDKs to export the reports to PDF.
Apply trace on RAS server and check what you find in RAS logs.
Check whether you can see timeout error is RAS logs. Usually if connection is lost and the RAS server no more have the session to write to the temp directory, we do see these errors.
Also, does the account that runs RAS have permissions to create a file in RAS's default temp directory? Are you getting any out of memory or out of disk space exceptions on App server or RAS, tracing RAS server is the way to move forward.
Thanks,
Prithvi

Yes

>>Check whether you can see timeout error is RAS logs.
How to configure tracing, and where are RAS logs? Is it configured in CMC --> Servers --> Crystal Report Services?
>>Also, does the account that runs RAS have permissions to create

Pretty sure yes.
>> Are you getting any out of memory or out of disk space exceptions

Not on App server.
For RAS, that's the problem, I am not sure where to look....... -

Hello,
While exporting Export reporting from BI4 getting exception
Can not create temp file---- Error code:-2147215357 [CRSDK00000615] Error code name:internal

I tried following solution according to the all forums but still issue exist.
Done changes mention in KB article In <Installation-dir-of-BO>\Common\4.0\java\CRConfig.XML we have to increase the JAVA heap MIN and Max size
<JVMMaxHeap>64000000</JVMMaxHeap> <JVMMinHeap>32000000</JVMMinHeap>
Increase the value in the ReportApplicationServer Services in the CMC for "Number of database records to read when previewing or refreshing a report". The value -1 is for unlimited records but not recommended for performance.
Check for temporary read write permission on server
Using SDK library from C:\Program Files (x86)\SAP Business Objects\SAP BusinessObjects Enterprise XI 4.0\java\lib
Can you please let me know is there anything missing.Hi,
We face the same problem with some BI4 reports.
The same report works well with the "Crystal Reports Viewers API", as used in Infoview, but not with the "Report Application Server (RAS) API".
This error appears after some time working on a report. If we reproduce the same report, but from zero, no problem.
Hope it can help.
