Jar file for multiple client JRE version

I have two jar file. Fjtable.jar & fjtable16.jar
fjtable.jar is for clients those who are using JRE 1.5 & fjtable16.jar is for jre 1.6 version client Users.
both the jar file i have given in
In formsweb.cfg :
Archive = fjtable.jar , fjtable16.jar
But this give error when accessing forms for those jre1.5 users.
Exception in thread "AWT-EventQueue-2" java.lang.UnsupportedClassVersionError: Bad version number in .class file
How do i give a condition in formsweb.cfg, if client java is jre1.5 then use fjtable.jar else use fjtable16.jar.

It's used in the page that calls the Forms configuration with the correct jars : this should tell you which JRE your client is on and can be adapted for your config:
<html>
<body>
<table width="100%">
<tr><td>Click on the link below to run your app:
<script src="http://www.java.com/js/deployJava.js"></script>
<script>
    var version = '1.6' ;
    if (deployJava.versionCheck(version)) {
      document.write("<a href=\"http://myhost.local/forms/frmservlet?config=app16\">MyApp v1.6</a>");
    } else {
      document.write("<a href=\"http://myhost.local/forms/frmservlet?config=app15\">MyApp v1.5</a>");
</script>
</td></tr>
</table>
</body>
</html>PS. Thanks Francois I'm sure this'll come in useful at some point know how to do this :)

JAR Files for multiple tracks

Hi All,
We have a scenario where we need to provide JAR files which needs to be accessible by all the tracks.Is there any solution which is being followed.
In the current landscape we have built external library DC's for each track and trying to access the JARS. But the limitation where we are struck up is this DC is being only accessible to DC's in that track but not to the remaining tracks.
Is there a global solution where we i can make my JAR file can be made accessible to multiple tracks.
Thanks & Regards,
Lokesh Kamana.

Hi,
Thats a good idea.
I have a SC component created in SLD and create a track for this and copy the ext lib DC to this track.
Define outbound connections for moving transports.
But how to create an SCA file for my DC.
ANS:-Just by clicking on assembly get a SCA file for this track and as outbound connection is defined this SCA gets moved to my track import that to all my tracks where i carry out my development.
While moving the transports to other environments do i need to move this SCA file also along with them.
Please let me know whether my understanding is correct or not.
Thanks & Regards,
Lokesh Kamana.

How to create multiple pof configuration files for c# client

Is there a way to have multiple pof files for c# coherence client?
Can I create a file called my-pof-config.xml with the following line...
<pof-config xmlns="http://schemas.tangosol.com/pof">
<user-type-list>
<include>assembly://Coherence/Tangosol.Config/coherence-pof-config.xml</include>
<include>file://pof-config.xml</include>
and here is what pof-config.xml file look like
<?xml version="1.0" encoding="UTF-8"?>
<pof-config xmlns="http://schemas.tangosol.com/pof">
<user-type-list>
In my C# visual studio project, this is where I load my-pof-config.xml in app.config
<coherence>
<cache-factory-config>coherence.xml</cache-factory-config>
<cache-config>coherence-cache-config.xml</cache-config>
<pof-config>my-pof-config.xml</pof-config>
</coherence>
and this is what I saw in the log...
2012-02-23 14:35:35,529 DEBUG Coherence (null) - 2012-02-23 14:35:35.529 level(thread=System.Threading.Thread): Loaded POF configuration from "FileResource(Uri = file://my-pof-config.xml, AbsolutePath = D:\worktrees\ads\mainline\v2\ads\demos_cs\build\my-pof-config.xml)"

I don't see pof-config.xml is loaded at "Loaded included POF configuration....". How do I get around it so I can load multiple pof configuration files for c# client?

Hi,
Not sure about C# but I would suggest try removing file:// from
<include>file://pof-config.xml</include>and keep pof-config.xml and my-pof-config.xml in the same directory.
Hope this helps!

How to manage one wsp and dll for multiple clients in farm environment

1. There is a product which is developed using C sharp , jquery,CSS and sharepoint object models which have been packaged into .wsp file. Whenever we introduce new functionality to the product we used to branch the
previous code as a version , say Version 1.0 and new functionality of the product will in another solution. This is how we are managing the code in TFS as versions. Each newer version will have new functionalities. We do not give latest functionality for all
the clients. Each client is having its own version of functionality. Technically in order to access the functionality, the wsp solution should be present in the solution repository which is available in SharePoint central administrator site. This solution
will be deployed on the client’s site. We are following the above process in SharePoint standalone installation where we used to purchase dedicated server per client and installed sql, SharePoint foundation 2010 as standalone installation and adding the client
related version of the code to the solution repository. Later host on the site which is created for that client purpose. This process is same for all the clients where we purchase individual server for each client .
Now we want to host our product in farm environment of sharepoint foundation 2010 where we are going to try 3 level architecture.
• SQL Server-In this sever we are going to install sql server 2008R2 standard edition. Which should serve the database service for all the web applications/sitecollections which we are going to create in Web front end server.
• Application server- In this server we are going to install the sharepoint as farm and will install search server express for serving search functionality for our product
• Web front end server- In this server we are going to add this server to Sharepoint farm which we have created in application server. Here we are going to create web applications and site collections for all the clients.
In this scenario how to manage multiple versions of same wsp solution?
Another major issue w.r.t the architecture of the product and new approach for client deployment as follow.We have CSS, jquery files for serving the functionality.These files have been mapped to 14 hive folder.If any changes we do one of the jquery file or
css file which is meant for latest version and not for old version, then how to manage this new functionality for that particular css or jquery file in 14 hive folder, since there is only one 14 hive folder. What is the best practice to make this happen? Another
thing is, how to manage dll files for individual client?

It sounds like you have a farm scoped solution at work. In that case you can only have a single instance of it per farm, you'd have to branch each version so they appear to be seperate solutions entirely (thus ruining your clients upgrade process).
Bluntly i don't think a single farm can manage all your user environments.

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

Virus scan failed Error on deploying a web application having a jar file for calling the applet on the jsp page

I have an applet application that i want to deploy on the Oracle cloud.
So i have created a jar file for the applet application and i am using this jar to call the applet on a jsp page.
But when i am delpoying my application on the java cloud, its giving me the below error:

Can't we deploy any application having applet or swing component's onto the cloud?
Or do we need to request for any extra permissions for the same?
Thanks,
Manoj

I don't see applets mentioned in the supported features nor in the unsupported features so not sure if they are supported you would likely need to contact the operations team to confirm.

Include an in-memory jar file for JSR-199 compilation

I want to compile a source file in memory, which requires a jar file that is also represented in memory. I used the JavaSourceFromString class recommended in the documentation for the class JavaCompiler and in a demo I found online that shows how to compile sources represented as String in memory. To represent the jar file, I used a similar trick to JavaSourceFromString:
public class JarJavaFileObjectFromByteArray extends SimpleJavaFileObject {
   * The contents of this jar file.
private final byte[] contents;
   * Constructs a new JarJavaFileObjectFromByteArray given the name and binary
   * contents of a jar file.
   * @param name the name of this jar file
   * @param contents the contents of this jar file
public JarJavaFileObjectFromByteArray(String name, byte[] contents) {
    super(newURI(name), Kind.OTHER);
    this.contents = contents;
... // code not shown ensures that the URI returned from newURI is of the form,
      // for instance, bytes:///MathConstants.jar, if the name of the jar file is MathConstants.jar
@Override
public InputStream openInputStream() throws IOException {
    return new ByteArrayInputStream(contents);
}However, I do not know how to alert the compiler that this jar file should be on the classpath. I tried this:
List<String> options = Arrays.asList(" -classpath bytes:///MathConstants.jar ");
CompilationTask task = compiler.getTask(null, fileManager, null, options, null, compilationUnits);but I get the following error when calling getTask:
java.lang.IllegalArgumentException: invalid flag: -classpath bytes:///MathConstants.jarI assume there is some way to tell the compiler, "look at the MathConstants.jar file that I am storing in memory when searching the classpath", but I do not know how to do this. I assumed that the options parameter for getTask represents command-line flags that would be passed to the compiler if this were happening on the command line (such as "-cp .", which also does not work), but perhaps this assumption is wrong.

Hi Bruce,
I have a question regarding loading a jar file by the compiler to dynamically compile with a source file. I hope you can probably offer me an idea on what has been missing or wrong with the source codes I have written for my application.
I am using Eclipse compiler to dynamically compile a class. In the class, I want it to make a reference to a jar file for compilation dynamically.
Here is the source of a test class I wrote:
import javax.servlet.http.HttpServlet;
class MyServlet extends HttpServlet {
}The import statement refers to the class javax.servlet.http.HttpServlet from the jar file C:\\Program Files\\Apache Software Foundation\\Tomcat 6.0\\lib\\servlet-api.jar placed in the file system.
In the method called compileClass (shown below), I used the path of the jar file to add to the option -classpath as you suggested.
     private static CompileClassResult compileClass(Writer out, String className, String classSource) {
          try {
               JavaCompiler javac = new EclipseCompiler();
               StandardJavaFileManager sjfm = javac.getStandardFileManager(null, null, null);
               SpecialClassLoader scl = new SpecialClassLoader();
               SpecialJavaFileManager fileManager = new SpecialJavaFileManager(sjfm, scl);
               List<String> options = new ArrayList<String>();
               options.addAll(Arrays.asList("-classpath", "C:\\Program Files\\Apache Software Foundation\\Tomcat 6.0\\lib\\servlet-api.jar"));
               List<MemorySource> compilationUnits = Arrays.asList(new MemorySource(className, classSource));
               DiagnosticListener<JavaFileObject> diagnosticListener = null;
               Iterable<String> classes = null;
               if (out == null) {
                    out = new PrintWriter(System.err);
               JavaCompiler.CompilationTask compile = javac.getTask(out, fileManager, diagnosticListener, options, classes, compilationUnits);
               boolean res = compile.call();
               if (res) {
                    //Need to modify the api to return an array of two elements - one classes and other bytecodes for all classes in the same class file.
                    return CompileClassResult.newInstance(scl.findClasses(), scl.findByteCodes());
          } catch (Exception e) {
               e.printStackTrace();
          return null;
     }I also extended the class ForwardingJavaFileManager as you suggested and have it delegated to the StandardJavaFileManager sent to the compiler mentioned in the method compileClass above. The extended class (called SpecialJavaFileManager) is as follows:
public class SpecialJavaFileManager extends ForwardingJavaFileManager<StandardJavaFileManager> {
     private SpecialClassLoader xcl;
     public SpecialJavaFileManager(StandardJavaFileManager sjfm, SpecialClassLoader xcl) {
          super(sjfm);
          System.out.println("SpecialJavaFileManager");
          this.xcl = xcl;
     public JavaFileObject getJavaFileForOutput(Location location, String name, JavaFileObject.Kind kind, FileObject sibling) throws IOException {
          System.out.println("getJavaFileForOutput");
          MemoryByteCode mbc = new MemoryByteCode(name);
          xcl.addClass(name, mbc);
          return mbc;
     public Iterable<JavaFileObject> list(JavaFileManager.Location loc, String pkg, Set kinds, boolean recurse) throws IOException {
          System.out.println("list ");
        List<JavaFileObject> result = new ArrayList<JavaFileObject>();
        for (JavaFileObject f : super.list(loc, pkg, kinds, recurse)) {
             System.out.println(f);
            result.add(f);
          return result;
}I run the application and the result shows that it didn't load the jar file into the memory as expected. From the output (below) I got, it doesn't seem to invoke the method list(...) in the class SpecialJavaFileManager.
SpecialJavaFileManager
1. ERROR in \MyServlet.java (at line 1)
     import javax.servlet.http.*;

Jar files for using BRM API's

Hello,
I am not able to locate the Jar files for using BRM API's. I have tried searching the forum and did not find the name or location from where I can get them. If they are available on the server I could ask the basis team to give me a copy. Any help would be greatly appreciated.
Regards
Preetam

Hi Adam,
I have created a New EJB Project for my proxy development. This is the usual way I develop proxies for any given service interface created in ESR. Now i am not sure how to create a dependency with the BRMS facade. If i find the jars i can add it as an external library when compiling.
Can you explain a bit more about what you ment by "developing the java proxy in a development component", how did you accomplish this when creating a proxy for a service interface?
