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 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 to add a directory into a jar file

Hi, guys, I want to add a package into a jar file. For example, my dirctory structrue
is org/test/, all files locate in the directory test, in org.test package. I want to
add the package into a jar file, test.jar. I use "java -cvf test.jar -C org/test/ .
But it says "jar: no match". How can I solve it.
thanks

Instead of 'java', use 'jar'.
All in all, try this: jar cvf test.jar -C org/test/*.class.

I need to sync my iPhone to new user id on the same mac. How do I keep my iPhone contacts and music library? I tried to sync and iTunes wanted to erase both.

When you say a new user ID, are you referring to your Apple ID that you use to make purchases in the iTunes Store, etc? Or are you talking about a new user account on the same Mac?

Add classpath in an executable jar file

This is my code:
URL[] urlArrayA = new URL[5];
urlArray[0] = sample1;
urlArray[1] = sample2;
URL[] urlArrayB = new URL[5];
urlArrayB[0] = sample3;
urlArrayB[1] = sample4;
URLClassLoader urlClassLoaderA = URLClassLoader.newInstance(urlArrayA);

could anyone please answer the question for me ? thank you...

Add 'soft link' of a shared file in the body of message.

I want to know if there is a way to hyperlink a shared file which is on a server and add it in the body of message rather than sending that whole file as an attachment. So that when the recipeint receives the e-mail, he/she can just click on the link and that particular file will open.
I hope my question is clear enough. I need your expert opinion in this matter. Is this do-able or am I crazy?

I tried doing the same thing. I guess I am doing something wrong.
I have a webserver and folder named projects under webserver. I want to access a file from the projects folder. Hence my absolute file path looks something like this:
\\Web_Server\web_server\projects\bci.doc . How can I make this path as URL? I understand that if I have any internet website or any ip address, I can hyperlink it. But I am not sure, how can I hyperlink a file path such as this.
I have tried the following code in the javamail:
String tempFileName ="Web_server/WEB_SERVER/Projects/BCI.doc";
</font>";
This did not help me.
Please help.
Thanking you in advance,

Update: actually this has nothing to do with i915 (I can see the issue earlier in the journal), and after hours of downgrading/reupgrading madness the problem just disappeared... It was probably a bug of Firefox because of the number of tabs opened in the same time or something like that... Maybe related to a website in particular, since I saw some libmozalloc segfault in the log. Anyway, topic invalidated.

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.

Hello Diego
The SAP GLOBAL 2.0 should be downloaded from the Service marketplace. Follow the URL : [http://service.sap.com/swdc|http://service.sap.com/swdc] and search for SAP GLOBAL.
You will find the following SWCV - XI CONTENT SAPGLOBAL 2.0. If you have relevant access, you can download the same as a .tpz file and then import it into your ESR.
Hope it clarifies things.
