JAR file to use in JSP

I have several JAR files(say parser.jar,xerces_1_2.jar, xerces_1_2_0.jar) with the same set of libraries in my tomcat/lib folder. They belong to different versions. I want to use a specific JAR file, say xerces_1_2.jar, in my JSP page irrespective of the order in which they are specified in the classpath. How do I do this? Thanks a buunch!

Well I have all those JAR file in the lib folder. The problem is I need my JSP file to pick the exact JAR file (xcerces_1_2.jar) rather than the one assigned by tomcat. How do I do that? Thanks.

Add jar files and use those classes at the runtime

Hi All,
I need to add some jar files at the runtime depends on which the user selects where the jar file is located and i need to import those classes in other class for some functionalities . I could add jar files by using the URLClassLoader and Class.forName("myjar.myclassname") is also succeeded and i have no clue how to use those classes with in the jar file as i couldn't import those classes also in the source because the jar files are being added at the runtime(This leads to class not found exception at the compile time).
I had found a complicated way of using those classes after being added at the run time as below.
   Class clazz = Class.forName(myClass);
            final Method method = clazz.getDeclaredMethod(requiredMethod, new Class[]{URL.class});
            final Object returned = method.invoke(clazz.newInstance(), new Object[]{request}); but, its really pain to use in this way in all the places.
Does any of you have simpler suggestions on how to achieve this?
Thanks,
Venky.

Thanks jschell. Yes, you are right. I had found that using reflection API is the only way to load classes at the run time. But according to our application using reflection makes the application little complex, so while start of the application or during other modifications, i am overwriting my jar file to the latest one using FileChannel class as below
      FileChannel ic = new FileInputStream("new.jar").getChannel();
      FileChannel oc = new FileOutputStream("old.jar").getChannel();
      ic.transferTo(0, ic.size(), oc);
      ic.close();
      oc.close();After this code is executed, our application totally uses the new jar file.It is little fast than using reflection. Is this a good idea?

Jar files for using BRM API's

Hello,
I am not able to locate the Jar files for using BRM API's. I have tried searching the forum and did not find the name or location from where I can get them. If they are available on the server I could ask the basis team to give me a copy. Any help would be greatly appreciated.

Hi Adam,
I have created a New EJB Project for my proxy development. This is the usual way I develop proxies for any given service interface created in ESR. Now i am not sure how to create a dependency with the BRMS facade. If i find the jars i can add it as an external library when compiling.
Can you explain a bit more about what you ment by "developing the java proxy in a development component", how did you accomplish this when creating a proxy for a service interface?

Hi all,
From where can I download the jar files to use JAXB 2.0?

To add the JNI dll to the jar file and use the dll inside the jar file

Hi to everybody,
I am new to java.
I want to add the JNI dll to the jar file and use it in the java class.
How can I achieve it.
Please help me.
Thanks in advance.
Regards,
M.Sivadhas.

can't be done because none of the known operating systems support reading binary libraries from .jar files ... you can add the binary to the jar but then you have to extract it...
besides, mixing platform specific and platfrom independent components is not a very good idea, i'd keep the dll out of the jar to begin with

Which jar file is required for jsp dynpro page programming ?

Hi all:
I use NWDS wizard to create one small jsp dynpro page application. However the project has some errors, it said "
This compilation unit indirectly references the missing type com.sapportals.htmlb.page.DynPage (typically some required class file is referencing a type outside the classpath) Test1.java NewParProject1/src.core/com/xinao/test line 0
" However, I found the class DynPage is not found in current project.
I have already added com.sap.portal.htmlb_api.jar into my project.
Where can I locate and find that jar file (which include the DynPage class ) ?

How to deploy jar file for use within mapping user-defined fcn

Hi all,
I have a java class I'd like to called from a mapping user-defined function.
Here's what I've done (but hasn't worked)
1. Added 'package com.<mycompany>.xi.util.base64 to the source class file and compiled it.
2. Created a sda with a plain provider.xml file, i.e. no references were made to any other library files.
3. Deployed the sda to the xi 3.0 j2ee server successfully using SDM.
4. Under the Visual Admin tool, I see that the library was deployed successfully.
5. In the import text box in the user-defined function (design time), I enter com.<mycompany>.xi.util.base64.*.
A syntax check returns an error indicating the package could not be found.
Can anyone give me pointers as to how I can get this working?
Thanks,
--jtb

Hey James,
No! That's not the right way!
What you have done is for accessing external JMS & JDBC drivers in their corresponding adapters. For the access inside a mapping user defined function, it's enough if you import the jar files.
Look at this blog and you will be very clear!

Problem in viewing a converted JavaHelp (jar) file (created using RH2002 to RoboHelp X5)

Hi,
I have a javahelp project (compressed javahelp) created using
RoboHelp 2002. The output files are jar files.
The source files are .mpj. When I view the existing jar files
without converting the project to .xpj I am able to view the jar
files.
However, this project needs to be upgraded to RHx5. During
conversion(.mpj to .xpj) everything seems to be working fine and
the javahelp files are generated. But when I try to view the jar
files nothing is diplayed.
I get the following error. Please see below.
Has anybody come across anything similar? Is there anything I
need to take care of before I upgrade to .xpj? I cannot locate the
glo.xml file in RH.
Best regards,
Urmi

Hi Colum,
Thanks for your reply.
Yes, I have gone through the Peter Grainge's article. It is
indeed very informative and I have installed the JDK and the JH
according to the instructions given therein. My installation seems
complete as the viewer works fine. The JDK version is 1.4.2_18 and
the JH version is 2.0. The environment variables have also been set
accordingly.
All this while I was thinking it is a Java issue so I have
tried out with different JDK versions.
But now I think it can be a tool issue because :
I can view the existing JavaHelp file with the current Java
viewer.(if I do not open the project in X5)
I can view Sun supplied sample jar files with the viewer.
I can create new JavaHelp files with RHX5 and the current JDK
and JH installation and view those files.
I cannot view the JavaHelp file if I convert the .mpj to .xpj
(the generate dialog works fine and says compilation is complete).
The Display button does not display the file. The view
command line command throws up the error mentioned in my earlier
mail.
Would appreciate any pointers.
Best regards,
Urmi

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.

Jar file downloaded using FTP gets damaged

Hi people, Am working on a solution that implements an auto update of an application developed using Java. I am using Apache commons package for downloading the updated JAR file from an FTP site. Once I have the new JAR file on my local machine, I double click it and I get the following error. Invalid or corrupt jarfile C:\FIDS\FIDS.jar When I use a different FTP client to download my JAR file, the file works well when double clicked. What could be happening on my JAR file. Thanks and regards.

What is your suggestion,that I use http? or ?That depends on what it's used for.

How to make jar files run using java.exe and not javaw.exe

Hi ,
I am developing a project in which there is an GUI which inturn will call a console . I have made it into an jar file now.
Here comes the problem. When i run the jar files , i don't get a console. While going through this forum, i came to know that jar runs using javaw.exe and this stops it from bring the console up.
Please suggest me a way of running the jar file through java.exe or any other method by which i can get an new console poping up.
PS : i cannot start the application itself in a system console , because the Console mode is an added feature and it is not to be displayed every time but only when the user intends to.

Thanks for the reply pbrockway2. But i think, i was not able to convey my problem properly.
I am supposed to start my application in a GUI mode ( No console are should be present at this point of time). Within the GUI , i have a option for working in the console ( i.e if console is choosen, then i start giving my output and take inputs from the console. I am trying to do this by just calling the "System.out "and "System.in" methods. )
Here is the problem. As i have started it through " jar " it would not have a associated console with it.
PS: i cannot have launching .bat file because that would result in my application having a console displayed at the very start of the application. I want the console to be displayed only when the user wants to start in console mode.
Please suggest me some ways of doing this. Can i create a console from my java program and then exit it.

Create a jar file programmatically using runtime.getruntime??

try
               String s[]={"cmd.exe","/c","C:\\programfiles\\java\\jdk1.6.0\\bin\\jar.exe","-cfm","jarname.jar","manifest.mft","classes.class"};
               Runtime.getRuntime().exec(s);
          catch(Exception er)
          }i want to ask, why this code doestn work, i want to create a jar file using the runtime.getruntime.exec command..
please correct me, thanks
is it possible??
thanks,

Probably because the working directory is not where you expect so does not contain the 'classes' directory or the manifest file. You can define the working directory by using the exec() command that has 3 arguments (setting the second to null) or you can use the full paths to the files/directories.
If you have no done so then you should certainly read
http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html
Edit: I just looked again at your post - 'classes.class' seems a funny name for your class file or for the root directory for your class files. Have you tested the 'jar' command from the command line? if not then do so.

Updating a running JAR file without using JDK

Hi guys, I have been stuck on this problem for days. I have a program that allows the user to log in and encrypt/decrypt files. This program must be stored on the removable drive and it should work on any operating system without requiring any installation of files. In order to store their login data, I wrote it to a shadow.txt file. My idea was to pack this shadow file into the JAR file so as not to create unnecessary files. I understand that in order to update JAR files, all I need to do is to do
Runtime.getRuntime().exec("jar uf login.jar shadow.txt");However, here's the problem. I cannot assume that every user PC has JDK installed. As JRE doesn't have jar.exe, that command won't work anymore. Furthermore, the JAR is currently in use. So even if the user has JDK, windows will never allow this command to go through. Anyone has any ideas?

I had similar requirement, except that, i used a war file.
Had a client.war file in JBoss deploy directory, and i needed to update client.jnlp file present in it.
But as jar.exe comes only with jdk, could not use jar -uf command.
But not sure if it works with other application server too,
in jboss we can explode the war file, meaning we can create a directory "client.war" in deploy directory and extract your client.war contents to it. Now when server starts, it considers the extracted directory as web archive application.
This extraction can be done with out using jar.exe. can be done using jarinputstream aswell.
Once the contents are extracted , the files in it can be modified with out jar.exe.
For my case it worked as my client.war file is not signed, although the resources inside are signed.
