WAR or JSP to serve HTML in JAR file?

Hi,
I want to keep a few hundred static help files in a JAR when I install my appliation on the server to ease installation and management. But what is the best way to serve them up? What litle I know about WARs seems to imply I can have HTML files in one and, with the server set up correctly, redirect a URI to find HTML files in there. Is that so? Is there an exmple out there?!
cheers,
Chuck

Hi,
Thanks, but to be clear, I want to ONLY have HTML files in this WAR. The rest of the appliation's servlets will not be part of this.
I am simply looking for an easy way to access the HTML files if I JAR them up. Using a WAR, there is no servlet/jsp required to redirect a URL request to an HTML file in the archive, right? What would the web.xml look like, or is it even needed, when there is no JSP associated with the WAR?
thanks,
Chuck

JSP referencinc taglib.tld in JAR file doesn't work.

I have some custom tags which work fine under Weblogic 5.1 when I do a
          normal deployment of files, including the taglib.tld. However, when I
          try to reference the taglib.tld located in a JAR file, then weblogic
          throws an error saying that it cannot resolve into a valid tag library.
          I am only doing this because I am testing the same site agains both
          iPlanet Web Server and Weblogic. iPlanet will only find the taglib.tld
          when it is in a JAR file.
          Can anyone shed some light on referencing the taglib.tld in a JAR file.
          This should work, as it is covered in the JSP 1.1 specification.
          FYI - the jar file is in the same location as the JSP which references
          it. The URI to the JAR file (in the JSP) is from the root of the site.
          Thanks for any help.

Welcome to the Sun forums.
Subject: My Applet Jar file doesn't work !! .
1) Note that one '!' denotes exclamation, whereas 2 or more often denotes a dweeb.
2) Since you are on your first post, I will point out that applets are an advanced topic, and should not be attempted by newbies.
3) "doesn't work" is very vague. It is likely to produce a reply like "maybe the applet is lazy - try flogging it".

..I have written this java applet :When posting code, code snippets, HTML/XML or input/output, please use the code tags. The code tags help retain the formatting and indentation of the sample. To use the code tags, select the sample and click the CODE button.
Also note that the most preferred form of code is an SSCCE *(<- link).* In an SSCCE, your would remove all but one button (if the actionPerformed fails with 6 or 7 buttons, trim it down to fail with just one or two.
i made a jar file :So does the applet work before you make the Jar file? Your post so far suggests the Jar file is the problem.
i created a file and named it MANIFEST.MF .i wrote inside it :
Main-Class: test
Then i placed it in a folder with the test.class .I created jar file using command line.
I entered the test.class path and then wrote this command :
jar cvfm myjar.jar MANIFEST.MF *.class
Then the jar file "myjar.jar" is created .
it's executed but this function "public void actionPerformed(ActionEvent e) " won't wrok.
i keep pressing the buttons but nothing is happening !!So you get 'no output in the console & no effect in the applet'?
What is the URL where I can see your applet failing?
As an aside, since Sun does not guarantee that applet clients will act on the showDocument command, even if it does not work, it would not be a 'bug'.

How to include a JSP page contained in a JAR file ?

Hello,
I have a Servlet in which I would like to include, in the Response, the content of a JSP page contained in an external JAR file included in my lib directory ?
Could someone help me please ?
Thanks in advance.

I don't think thats possible with the standard j2ee server.
There are probably ways around it, but it would involve a large component of custom coding.

Problem with JSP using bean packaged in jar file

Hi,
          I am trying to use a java bean in a jsp file. The java bean is packaged
          into a jar file. I am getting class not found compilation error. If the
          bean remains to be a seperated class file, everything work well.
          Does anyone know how I can use bean in a jar file within jsp , i.e. to
          allow the bean to be found during compilation ?
          Thanks,
          Terence.
          [email protected]


Jacek,
          Thanks for replying.
          My JSP's are just files in my document root . However, I found a solution to
          my
          problem. That is to have the jar file defined in my weblogic.class.path. I may
          have missed some files in my original jar file which causes my problem.
          Mayby I should package everything into a web application for deployment. That
          will be my next step.
          Thanks anyway.
          Terence.

Web server cannot access .jar file?

Hi all,
I'm using NetBeans 4.1 IDE with the bundled Tomcat 5.5.7 on Windows XP sp2.
I have a .jar file which I must make available for the web server (not only for my web app). So I did the following:
Added a CLASSPATH variable to the user environment (pointing to my .jar file),
Shutdown Tomcat,
Restarted the IDE (because it is responsible for launching Tomcat, so Tomcat inherits its environment vairables from the IDE),
and finally ran my web-app.
The result: the web app could not find classes from the .jar file.
However, if I copy the .jar to the server's common/lib directory, everything's ok!
Why? I'm sure I don't have to put .jars in common/lib in order to make them visible by the server! I've read that adding them to the CLASSPATH is just as good solution... what is going on?

Tomcat has its own ideas about classpath. In particular it ignores the system classpath, so that each web application can have its own seperate one.
Jar files should normally live in the /WEB-INF/lib directory of your application.
If you want to share them across multiple apps, use the /shared/lib directory.
/common/lib should not normally be used except for database drivers when using tomcats JNDI datasources.

Location of SQL Server JDBC Driver jar files

Hi All,
I have a java applet connecting to SQL Server 2000 through MS SQL Server 2000 jdbc driver. It works fine on all client machines only if I copy the three jar files of the driver (msbase.jar....) into ext folder of java. If not, I get an error message saying error establishing socket. Why is it necessary to copy these 3 files on to client machines when all the other jar files can be easily accessed from the server?
Any ideas?
Thanks,
Manish

I have problem with the BPEL server caching the jar file of Instance

Is there any way to undeploy and redeploy a process where you have changes to the underlying DA, without the BEPL server being restarted. This always works in my Local BPEL server in my Laptop. But when deploying in the hosted BPEL enviroment it becomes a big problem in getting it restarted when ever I MAKE changes.
Is there any other way to disable the Cache of the instance and make it use the newer version uploaded. One more thing if the connection to a database is severed, then the DA will not work until the server is restarted. All the instances using the said connection is failing with either "Invalid Datatype" or "Socket Read exception". Can someone help!!
Thanks,
Prabhakar

Hi,
have you tried to kill the session of the DA in the database?

Calling jar file from jsp - serious problem !

Hi there, I'm trying to call a jar from a jsp file. I need an import clause in my jsp, to the class I want to use.
I'm using eclipse, and while i"m writing "<%= " and the begining of my class name , he autocompletes it and automatically puts an import of my class in the top of the html. It is very convenient , but the problem is that he underling the class name (in the impot: <%@page import="myClass"%>), and I get "The import myClass cannot be resolved" error.
I got an advice to put my class in a package, since it was in a default package. I did it. But now I have 2 problems:
1. I can't run my jar in command window: java - jar myJar.jar. in gives me: Exception in thread "main" java.lang.NoClassDefFoundError....
2. I still get an error - "The import myClass cannot be resolved" in the jsp, although I threw the old jar (that his class I want to use was out of package), and brought a new jar after creating it.
I hope I managed to clarify myself. I'll be thankful of any help !!!

Hi MSoldier.
There are two ways to do this:
1) You use the java.lang.Runtime classes to start the java application in your JAR file, just like you would have done it from the command line. The Runtime class has three different exec() methods that can be used to run any program just like you would from the command line. Remember, using this method you will have to write everything just like if you run your Java application from the command line, incl. classpath etc. This way your Java application will be run as a separate process. When the application finishes the process is shutdown and the resources (RAM etc.) taken by it freed, just like when you shutdown any other application.
2) You can open the JAR file yourself from inside the JSP page, look inside the META-INF file to find the main class, and then calls the main class main method. There is an example of how to do this in the Java Tutorial available from Sun under the JAR files track. Check these links :
The Java Tutorial at Sun
http://java.sun.com/docs/books/tutorial/
The JAR File Tutorial at Sun
http://java.sun.com/docs/books/tutorial/jar/index.html
Opening JAR Files via the Java JAR File API
http://java.sun.com/docs/books/tutorial/jar/api/index.html
Note however, if you have just created some classes that you want to use from inside your JSP pages, and not a separate application that needs to be run separately, you should just include the JAR file with your custom classes inside the WEB-INF/lib directory. These classes are then automatically available to your JSP pages, just like the rest of the Java API.
I hope this answers your questions,
Kind Regards,

JAR files deployed to EBS server a not loaded by server

Dear All,
We deployed JAR files to Apache(Jserver) of EBS server, we put jar files to $OA_JAVA and added content of jar file names into jserv.properties, then we re-started the Apache(Jserver), but the JAR files are not loaded by server, we checked the properties file and the path of JAR files are both OK, what may cause this kind of issue?
Currently, we are working on the Accounts Payables interface, which need to call java scripts to upload the log file to Google drive, and we need to include some Google java files in the class path, so these java files are third party's, how to config these java files under Oracle?
Thanks,
Jackie

Hello Mike,
It customization jar file.
And customer wants to load this jar file to EBS apache server, so that they can use it to do some development work?
Now, they wants to know how to load it?

Sharing jar files across multiple web sites

Dear all,
We have an applet as part of an embedded device. I wish to share the jar files across multiple devices. i.e. Accessing 192.168.0.1 shouldn't download the jar files again if the same jar files exist in the cache as a result of download from 192.168.0.2. We are having very large applet jar files, hence reducing download times is a top priority. Is there some way to do that ? Will java web start help in this ?
regards,
Jay

generally for avoiding applet downloading again the best solution is to use applet cahing, just add cache_archive in your html code (for full reference please go to the jdk javadoc ). Of course the problem are diffrent ips 192.168.0.1 and 192.168.0.2, applet caching will work ONLY for one ip, when you serv second sever name/diffrent ip client jvm will treat this applet as something new and will download it . The best solution i think is to sever everything on one server page/ip etc, but as you mentioned it is not good solution.
Well you can make it if you want to serve your big jar file on diffrent ips/severs, How? You should ctreate small certified applet jar , inside it should be code that will download your huge jar file from any location you want and store IT on CLIENT machine, becouse that jar will be certified so applet with file functions will not ask user to accept dialogs etc, so that applet will create locall on client machine little cache were all files that were downloaded will be stored. And again when user will acess your page that small certfied jar file will check if cache folder exist and if inside it is your huge file.
cheers

Why -jar option used to install a software which is in executable jar file?

Hi all,

can any one clarify my doubt...
thanks in advance

According to the Jar Guide (http://java.sun.com/j2se/1.4.2/docs/guide/jar/jarGuide.html)
Executable Jar Files
On Microsoft Windows systems, the Java 2 Runtime Environment's installation program will register a default association for Jar files so that double-clicking a Jar file on the desktop will automatically run it with javaw -jar. Dependent extensions bundled with the application will also be loaded automatically. This feature makes the end-user runtime environment easier to use on Microsoft Windows systems.
The Solaris 2.6 kernel has already been extended to recognize the special "magic" number that identifies a Jar file, and to invoke java -jar on such a Jar file as if it were a native Solaris executable. A application packaged in a Jar file can thus be executed directly from the command line or by clicking an icon on the CDE desktop.
Despite that every JAR file can be executed as a program if and only if the META-INF/Manifest.mf contains the Main-Class tag. This done through java -jar jarfile.jar

How to include .jar files in coldfusion code

To Integrate our cfm code with paypal jar files we do the
following steps with our local coldfusion server ,and to run and
integrate the paypal Java SDK jar files, I think we need to do the
same process on the server, can you suggest any thing to do the
following setting for my domain on the server, without setting the
class path in coldfusion administrator.
The ColdFusion application server must be configured to know
the location of the PayPal JAR
files, and your ColdFusion Markup (CFM) pages must be
configured with the absolute path to
the PayPal API certificate for the PayPal API user on whose
behalf the calls are made.
1. Install the PayPal Java SDK “Installing the
SDK”.
2. Copy a subset of the Java SDK JAR files to a location
accessible by the ColdFusion
application server. The JAR files are in SDK_root\lib and
their exact names are as
follows:
– bcmail-jdk14-128.jar
– bcprov-jdk14-128.jar
– paypal_base.jar
– paypal_stubs.jar
sax2.jar
– xerces.jar
– xpp3-1.1.3.4d_b4_min.jar
– xstream.jar-1.1.3.jar
3. With the ColdFusion Application Server Administrator, add
the absolute path of the
location you determined in Step 2 to the Java and JVM
CLASSPATH environment variable.
4. Restart the ColdFusion Application Server.
Suggest me how to include .jar files without setting
classpath.

> Suggest me how to include .jar files without setting
classpath.
Copy them to {CF_HOME}\lib, where {CF_HOME} is, for example,
C:\CFusionMX7. Restart Coldfusion.
