How to use jar files without setting classpath

Hi,
I have a situvation, I can not set classpath, but i have to use jar files, how can I do that.

URL[] urls = new URL[]{pathToJar, pathToAnotherJar, ...};
URLClassLoader urlc = new URLClassLoader(urls);
Now load classes within the jars loaded by the urlc classloader as needed. This is a limited approach, you can mostly use interfaces to work with classes loaded by the custom loader instance above and your existing classes.

What is directory where I can put in jar file without specify classpath ?

hi,
Is there any directory in weblogic similar to the directory of WEB-INF/lib/ where I can throw a jar file in without specify classpath explicitly.
The reason I'm looking for such directory is :
-- I do not want to specify classpath explicitly
-- I'd like it outside of an application so that it stay even if the application redeployed.
Thanks

Hi Aacc,
The domain library directory that you are looking for is usually $DOMAIN_DIR/lib, for example "C:\Oracle\WLS_Middleware10.3.4\user_projects\domains\test_domain_1\lib" (Windows) or "/u01/weblogic/domains/my_domain/lib" (Linux/Unix).
The jars located in this directory will be picked up and added dynamically to the end of the server classpath at server startup. The jars will be ordered lexically in the classpath. The domain library directory is one mechanism that can be used for adding application libraries to the server classpath.
You can override the $DOMAIN_DIR/lib directory using the -Dweblogic.ext.dirs system property during startup. This property specifies a list of directories to pick up jars from and dynamically append to the end of the server classpath using java.io.File.pathSeparator as the delimiter between path entries.

How to use vector file without adobe illustrator?? please help

I am using the free trial period of adobe illustrator to creat a logo. I don't want to buy illustrator b/c I don't plan on using the program for anything else, I would like to save my logo in some kind of vector format so I can use it for lots of different printing options. But I can't figure out how to do this b.c my computer won't open the file without illustrator. Is there anyway to creat a usable print friendly logo without buying illustrator? Thanks for any help!

I believe if you export it to wmf or emf you will have a Vector file that can be used in word or powerpoint and can be placed in other programs as can ai files which can be placed in word or powerpoint documents as vector files.
Flash (swf) is another way of saving it and it is also vector.
However even though you say you will never have use for Illustrator which is what I thought in 1995 when I use it to create a logo, I soon found more use for it and every year since have found a project that has rewarded me many times the cost of the application once I had purchased it. Most of which I never thought I had the need for and probably would not have even made the attempt to make the effort and the profit if I did not own the license.
And every time I say to myself what do i have this application for the opportunities arises yet again.
I thought I would share my experience with you.

How to use JAR files

I have my servlet in a JAR file. When I try to execute it I get an
          error saying File Not Found.
          Do I have to change something in the weblogic.properties file? I
          registered the Servlet but not the jar file.
          Thanks


          Did this work in 4.03? We had a super class (FetchServlet.java) defined
          in the jar and a jhtml page extended that. It worked fine then but now
          I'm having the same "File Not Found" problem when converting to 4.5.1.
          Help on this would be awesome, I've been messing around with the classpath
          trying to fix this for a week.
          Thanks,
          Josh

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

Copy them to {CF_HOME}\lib, where {CF_HOME} is, for example,
C:\CFusionMX7. Restart Coldfusion.

Using JAR file in running application and POI !

Hi all
I am trying to use POI HSSF f(for the first time, So pls bear with me!)or creating excel file from my java Application. I am using the jar file :
poi-2.0-RC2-20040102.jar. Not sure if its the correct one. So If I am wrong pls correct me.
Now I am creating a bat file to compile my application:
@echo off
C:\jdk1.3.1_04\bin\javac -classpath C:\POI\poi-2.0-RC2-20040102.jar MyApp.java
pauseIt compiles fine. Now If I try to use the jar file in run.bat for running my application, it says NoClassDef FoundError:MyApp. Here is my run.bat
java -classpath C:\POI\poi-2.0-RC2-20040102.jar MyApp
pauseI am not able to run my application with this run.bat file . If I change the content to:
"java MyApp.java"
It runs but give me error: NOClassDefFoundError:import org.apache.poi.hssf.usermodel.HSSFWorkbook
Pls suggest me about how to use jar file in running my app and how to rresolve workbook finding problem.
Reagrds

Try this:
java -classpath .;C:\POI\poi-2.0-RC2-20040102.jar MyApp
pauseNote the "dot semi-colon" at the start of the CLASSPATH. That puts the current directory in the CLASSPATH, which is where MyApp.class lives. (No package, right?)
See if that works better.

Use jar file for one servlet in one application (not global in classpath)

I have a servlet application that needs a jar file to load with one particular servlet. If I put the classpath to the jar file in the jvm12.conf, the servlet loads fine. I can't run it like that, however, since I use another jar file by the same name in a different application. I would like to specify it only with the servlet that needs it. According to the online help file, it says more than one jar, zip, or class file can be specified in the servlet classpath, but that doesn't seem to be the case. We're running iPlanet 4.1. I've tried adding the classpath to the jar file after the classpath for the servlet itself (servlet.properties), but it gives the class not found error for that function. Is there a way to do this? Context.properties, maybe? I can't find any instructions on setting that up.

You might have better luck asking this question on a web server forum. This is an application server forum and most people here are going to more experienced with iAS.

Its urgent how to use calss file of jar located in lib folder

how to use calss file of jar located in lib folder.
i want to use RowSetDynaClass class which is in beanutil jar file which is in my lib folder .if i use that class in my jsp following error is coming.
Class RowSetDynaClass not found.
RowSetDynaClass resultSet = new RowSetDynaClass(rs, false);
how to access class in jar file.
please help

You have to either refer to the class in its fully quallified name, or import it into the JSP:
<%
some.full.packagename.RowSetDynaClass resultSet = new some.full.packagename.RowSetDynaClass(rs,false);
...-or-
<%@ page import="some.full.packagename.RowSetDynaClass" %>
<%
RowSetDynaClass resultSet = new RowSetDynaClass(rs, false);
...As long as the class has public visibility and you have re-started the server/servlet context since you added the JAR.

   can any one explain the procedure step by step how to convert jar file into deployment archive file in order to succesfully into XI server.
          thanks i advance. points will be rewarded.

Hi Rajesh,
JAR file in itself in not deployable.
So v need to envelop this jar file into an EAR file and then v deploy this EAR file on SDM.
