How to call a .jar file in JSP

Hi Folks,
I would like to know how to call a .jar file in a JSP page..
Thanks in adv.

Any web app creating tutorial can. You know, if this doesn't ring a bell with you at all, I don't really feel inclined to explain it to you because I think you shouldn't yet be dealing with JEE in the first place.

How to package other jar files into one jar?

How to package other jar files into one jar? How can i get the class in the inner jar file?

Generally not a good idea. The Java runtime won't be able to load classes from those "inner" jars, you'd have to write your own classloader to do that. It's not a brilliant idea, generally, anyway, since the point of having lots of jars is to keep your application modular. Bundling them all together like that means you have to re-deploy the whole thing to fix, for instance, one small bug in one small library
If you really want to do this, there's an Eclipse plugin called FatJar, but I urge you to consider whether you really want to do it first.

How to call external jar files in EJB project for CE

Hi,
I would be thankful if someone could help me with this -
I need to call the external jar files into my EJB project - Here is what I have done and am getting runtime exception as -
java.lang.RuntimeException: java.lang.NoClassDefFoundError: com/glance/pdf/pt/PTDoc
1. Created a EJB project" HelloWorld " using Java perspective in NWDS 7.1 called with client as HelloWorldClient and EAR project as HelloWorldEAR.
2. Am working on HelloWorld project (1st one).
3. In my code I am instantiating a class which is a class in one of the external jar file that I need to refer in my project.
4. I have set the Java Build path but it works only for the compile time and fails during runtime.
5. Have read I need to create external library DC and refer in my project "HelloWorld".
Can anyone help me with exact steps what needs to be done - during creation of external library project and then for my "HelloWorld" EJB project. How would I be able to reference or set the external library project in my EJB project?
Looking forward to hear from experts.
Thanks,
Shiv

Hi Edson,
I tried it , but it still gives me runtime exception.
javax.ejb.EJBException: nested exception is: java.lang.RuntimeException: java.lang.NoClassDefFoundError: com/glance/pdf/pt/PTDoc
java.lang.RuntimeException: java.lang.NoClassDefFoundError: com/glance/pdf/pt/PTDoc
Steps I performed are -
1. Created a library project and created 2 Public parts "Compilation" and "Assembly"
2. Build the library project.
Now in my EJB project using Project Explorer - set the classpath and added both compilation jar and assembly jar files.
This is how the classpath entries for external library looks like -
<classpathentry kind="lib" path="/LocalDevelopmentLocalDevelopmentexternallibrarypdftoolsforwatermarkingdemo.sap.com/gen/default/public/WatermarkAssembly/lib/java/demo.sap.comexternallibrarypdftoolsforwatermarking~WatermarkAssembly.jar"/>
<classpathentry kind="lib" path="/LocalDevelopmentLocalDevelopmentexternallibrarypdftoolsforwatermarkingdemo.sap.com/gen/default/public/WatermarkCompilation/lib/java/demo.sap.comexternallibrarypdftoolsforwatermarking~WatermarkCompilation.jar"/>
I have also added the jar files I used in my external library project as "User Library" from Java Build Path . I dont do it , then the code fails during compilation itself.

ServiceBus java callout - how to pack the JAR file with libraries?

Hello
I want to use a Java Callout from a Service Bus flow.
What is the correct way to pack the JAR file with its nessecary libraries?
I tried different methods to pack my JAR, but yet, as though the Java runs perfectly from the Workshop (Eclipse) , when I am trying to use the exported Jar on the ServiceBus flow, it fails with an ClassNotFoundException.
I would really appreciate your advice here.
Thanks
Koby

Well.. Looking inside my exported JAR file, I got all of the files there inside, including the jar file containing the library.
What I'm trying to do is run a simple java program that connect through SSH and therefore use an SSH library.
On the workshop I got it as an imported library JAR. And it works perfectly there.
Any idea?
Here's the complete error I get:
<BEA-382515> <Callout to java method "public static java.lang.String sshpackage.SshProg.remoteScriptInvoke(java.lang.String,java.lang.String,java.lang.String,java.lang.String)" resulted in exception: null

In .jar file how can I call API's of other .Jar file

Hi all,
I have created a "MyApplication.jar" file that dose not need any other .jar file Like xercesImpl.jar thne it is working fine.
but If I make the .jar file of application that needs xercesImpl.jar API's
of this .jar file then how I can call that xercesImpl.jar in my Application.jar newly created.
please help me
Thanks in advance.

either add the other jar file to your classpath or do the following (taken from http://javaalmanac.com/egs/java.lang/LoadClass.html)
e68. Loading a Class That Is Not on the Classpath
A URLClassLoader can be used to load classes in any directory.
    // Create a File object on the root of the directory containing the class file
    File file = new File("c:\\myclasses\\");
    try {
        // Convert File to a URL
        URL url = file.toURL();          // file:/c:/myclasses/
        URL[] urls = new URL[]{url};
        // Create a new class loader with the directory
        ClassLoader cl = new URLClassLoader(urls);
        // Load in the class; MyClass.class should be located in
        // the directory file:/c:/myclasses/com/mycompany
        Class cls = cl.loadClass("com.mycompany.MyClass");
    } catch (MalformedURLException e) {
    } catch (ClassNotFoundException e) {
    }

How to call a html file in a java file

how to call a html file inside a java file ?

Hopeless. Are you by any chance a rare gas? You seem completely inert. LOL You totally pwned him there :rolls eyes:
well, no, I think he's looking for something to this degree:
in HTML, there is a mailto: command that makes the system default handled way to email emails open up. He's looking for a command thats very nice and opens a html file in the system default browser.
So, Dick, Runtime.exec would work execpt that he needs a way to find the default system browser to call exec on, AND he has to know how to pass html file locations to the executable via command line arguments
He just didnt try to phrase it at all :P
