How do I add my own JAR file to the classpath?

When I put a JAR file containing several compiled Java classes in the '/opt/SUNWips/lib' directory they are not found while compiling a JSP-Provider. When I extract them from the JAR it is not a problem (I think because the '/opt/SUNWips/lib' directory is already in the classpath).
Where can I add my JAR to the classpath?

I have been successfully editing the jvm12.conf file to add jars. This is
the web server config file in
/opt/netscape/server4/http-your.server.com/config directory. Add to the
jvm.classpath line with all the other jars. Yes, lib is in the path, but
Java doesn't see inside the jars unless they are explicitly in the path.

Do I need to add to add a new jar file to the WLS ?

I am new to java development and would like to know if I were to use a new jar
file developed by another party in my EJB development, do I need to have this
jar file available in WLS when I deploy the EJB to it ?
I think this is not required but just need a confirmation.
Thanks

Hi,
I take this to mean you are using java classes from the 3rd party jar in your
EJB bean class. If that is the case, then you need the jar file in your classpath
when you compile the EJB classes.
Also, you will need the jar file to be in the classpath when the EJB is used.
You can do this in a variety of ways. If the 3rd party jar is going to change
infrequently, then you can put it in the system CLASSPATH in your startWebLogic
script. Or you can add all the classes of the jar file in the root level of the
EJB (Yuck!!).
Perhaps the best answer is to create an enterprise application (EAR). Then you
place the jar file in the root level of the EAR. In the META-INF\MANIFEST.MF
file of the EJB place
Class-Path: filename.jar
Then when you build the .ear file use:
jar -cvfm ..\commuterLog.jar META-INF\MANIFEST.MF *
hope this helps,

How can i add update signed jar file

I am developing an applet which requires signing to run in a browser.
I am developing supporting classes. But these class files have to be added
to the jar. Isnt it??
But to test the applet i need to load it in the browser each time i modify the class files. So the jar file need to be updated every time. But an
IOError
is being displayed when i try to update the signed jar file.
How can i update signed jar file?? Or is there any othe way to test the signed applet during development??

How can i update signed jar file?You can't, the signature is there to make sure the content of the jare hasn't been messed
with.
Either recreate the jar and re sign it or set up a policy during testing.

How Do I Add an Existing htm file to the list of pages in Contribute ?

We have a copy of Contribute. We were told that you could
create pdf files on the fly - - when we tried to do this we got an
error message saying we needed to have Adobe 8 pdf creator. This is
more expense to an already expensive project. I can create a web
page from Excel or WORD and I want to know how to link that page in
Contribute. Can anyone please help ? Many thanks,

I think you think of:
Project settings:
Configurations-Development-Libraries...
There you can create a new Library which contains your jar..
And also it is in Tools/Manage libraries menu..
There you must add user libraries

Which jar file for the classpath ?

At my office on my machine i have weblogic 8.1 and tomcat installed.
weblogic have 2.3 version of servlet and
tomcat have 2.4 version of servlet
weblogic is for production purpose (development of servlet, jsp and ejb)
and tomcat is for my own practice. (just for servlet and jsp)
i have weblogic.jar as well as servlet-api.jar in my class path.
now when i compile my servlets which jar file the compiler will use to create the classes.
if the compiler chooses servlet-api.jar will my servlet run in weblogic
else
if the compiler chooses weblogic.jar will my servlet run in tomcat

i have weblogic.jar as well as servlet-api.jar in my class path.What does this mean? Do you have a system CLASSPATH environment variable?
Bad idea.
now when i compile my servlets which jar file the
compiler will use to create the classes.You should set CLASSPATH using the -classpath option on javac.exe.
The compiler won't "choose" anything, because it has no idea how you'll deploy. It'll use the one that you tell it to. If you have just a system CLASSPATH it'll always use the first JAR that it finds with the packages it needs.
You need to specify exactly what you want the compiler to use.
In the case of servlet.jar it might not matter, because that's pretty standard. JSPs and EJBs are another story, however. If you change deployment, it's best to recompile and repackage the Web app.
Learn Ant. It'll help you automate this.

Including jar files in the classpath while compiling

While I compile, I want my class to be able to find the two jar files that are in the same directory as the class that I'm trying to compile.
c:\brandNew\src\myClass.java
c:\brandNew\src\lsw-services.jar
c:\brandNew\src\jdom.jar

If you are compiling in c:\brandnew\src
you do
javac -cp lsw-services.jar;jdom.jar myClass.java

How can I add a .mov video file to the beginning of an existing .mp4 video file?

I normally use final cut for all of my editing but Im having a lot of trouble converting this mp4 with bad pixelation.
The mp4 is my only master copy of my original 8mm student film.
It has some bad opening titles I need to alter and I need to slap my production logo on the front before I can even think of releasing this again.
Any ideas?

Give me a convenient method to add an external jar file to JRE.

At past, when i use some external frameworks like struts,servlet, i should set the classpath as:
.;C:\jdk1.5.0\lib\tools.jar;C:\jdk1.5.0\lib\xercesImpl.jar;C:\ApacheGroup\Tomcat 5.5\common\lib\servlet-api.jar;C:\ApacheGroup\Tomcat 5.5\common\lib\struts.jar;C:\classes\;C:\ApacheGroup\Tomcat 5.5\webapps\struts-blank\WEB-INF\classes\
when i want to use an exeternal framework, i must add the %INSTALL_PATH%\someframeworkname.jar to the classpath.
But i feel that is inconvenient for me, for example,I want to use jaxp,jaxr,jaxm,jaxrpc,saaj, I must add each of the jar file to the classpath.
I think that must be a convenient method to do that?
Can u give me a method?

hi
As I think u have to follow this step to use external jar in jre.
1. Find installed jre path in one variable
2. At Installation time add jar file to lib
U can get jre path using System property

How do I add a jar file into the build path of the compiler?

Hey,
I'm trying to import a jar file into the build path of the compilation process, but it does not find the packages or the classes that are in it.
I think I don't add it right...
          ArrayList<String> options=new ArrayList<String>();
          options.add("-d");
          options.add(targetDirectory);
          options.add("-classpath");
          for(String str:includeDirectory)
               options.add(str);
          if (!compiler.getTask(writer, fileManager, diagnostics, options, classes, compilationUnits).call());
                ....and I've tried this way:
     public void setTargetDirectory(String targetDirectory) {
          this.targetDirectory = "-d " + targetDirectory;
     private void compile(Iterable<? extends JavaFileObject> compilationUnits) throws Exception {
          ArrayList<String> options = new ArrayList<String>();
          options.add(targetDirectory);
          String classPath="-cp ";// tried this also with "-classpath"
          for (String str : includeDirectory)
               classPath+=str+":";
          options.add(classPath);
     if (!compiler.getTask(writer, fileManager, diagnostics, options, classes, compilationUnits).call())
          // throw new Exception("Compilation Error");
     }Thanks in advance,
Adam.

Thank you for your reply,
Q: Are there .class files in that directory in that jar file? (the compiler doesn't ( can't )) look for directories, it can just look for specific files , and scan to get a list of all files matching certain criteria. So if there are no class files, it will say the package doesn't exist, even if there is a directory, possibly containing other files.yes there are class files in the jar, the tree structure:
j2MeDataChunkGenerator_Plugin\(lots of class files)
META-INF\manifest.mf
and thats it.
, your code will only work on windows because other platforms use a different path separator. You should use java.io.File.pathSeparator not explicit ';" when building your classpath. (this is unrelated to your problem, but you should correct it)will do, thanks.
Q: Is that error in your post formatted by your own diagnostics? (we could possibly help you better if we didn't have to guess!!)I would not post my own error code, this text is generated by the compiler diagnostic.
{code}
     System.err.println(" Error details: " + diagnostic.getMessage(null));
{code}
Q: Is line 3 of ImageCroper_Editor.java (sic) an import statement? (we could possibly help you better if we didn't have to guess!!)it is an import error... didn't the error message stated that it is an import problem? wired, I'm sure before it did. anyway it is an import error.
Also you don't show us what the variable includeDirectory is in terms of type, and contents, that might be helpful. (we could possibly help you better if we didn't have to guess!!)It has only one String object: "D:\%Important Documents\WorkSpaces\PacMan\ApplicationManager\Plug-in\Data Chunk Designer.jar"
the last file on the classpath list.
Q: Have you proven this? that i did post, in this long line of text.
Q: Is the compiler finding other classes (in other packages) in that same jar file?No. all the class files are in the jar, they all have entries that start with "j2MeDataChunkGenerator_Plugin\*.class", and since I get 47 errors I guess it does not load any other class.
thank you for you comments, the problem with having these errors, is that I can't even get a piece of information where this error is coming from, only that it is an import loading error package not found, what does that mean? that the jar was not loaded in compilation(no error about this), that the jar is corrupted(no error about this), that the path is incorrect(it is correct I made sure), that there is no such package in the jar(There is), that the compiler does not load the package(does it even do that?), really I can't even guess why this happens, I've been at this on and of all day today, really annoying.
Thanks,
Adam.

How can I add jar files into the namespace in code?

My friends:

URL[] urlArrayB = new URL[5];
urlArrayB[0] = sample3;
urlArrayB[1] = sample4;
URLClassLoader urlClassLoaderA = URLClassLoader.newInstance(urlArrayA);
URLClassLoader urlClassLoaderB = URLClassLoader.newInstance(urlArrayB);

How to refer a .jar file in the code.

How to refer a .jar file in the code.
I want to use a library dnsjava.jar, which I download from the internet. I want to know how to refer it
If I am compiling the code on Solaris
If I compiling the code on windows using eclipse.
I added the following line in my code to refer to this library. But it always complains of not found the class
import org.xbill.DNS.*;
I tried the following to add this library but did not work
On eclipse/windows: Went to window-> preferences -> BuildPath _> class path Variable.
On Solaris: Could not add this library /opt/java_reference/v1.6.0_04/jre/lib. Although I am logged in as root, but not able to add the library there. Complains of Permission denied.

Set the classpath option when compiling.
javac -classpath /path/to/lib/dnsjava.jar YourProgram.java
I don't use Eclipse, but it probably has a library list on your project preferences. Add it there.

Henrique Abreu
