Compiling a osgi bundle related java file

Hi,
i am working on OSGi technology.i have downloaded the Java Embedded Server .i am able to run the framework & run the sample bundles(jar files which r already given).But few other examples r also given where the .java file & manifest files r present.i need to create the jar file & install.i am facing the problem with compilation of Activator.java (filename).the package org.osgi.framework(related interface used in program).i have imported all the required pkges.& also include the framework.jar in the classpath
(8 errors)
errrors:cannot resolve symbol
symbol :class BundleActivator
import org.osgi.framework.BundleActivator
similarly for " " .BundleContext
similarly for " " .BundleException
Plz let me know the solution.
Regards,
Tony

Apparently the org.osgi.framework package isn't accessible. Check the installation instructions, and read this documentation about classpath and finding classes:

can anyone tell me whats the problem and why am i facing this error

Hi Again,
Now with a different problem.
I have removed configuration and imported the configuration again. But now it is not recognizing API ( created by me with all common classes as java project).
Structre of the application is as follows
Cedapp - ear file
Cedejb - ejb module
Cedweb web module
Cedapi - java project with common classes used in both ejb module and web module and published as library. This refered in both the ejbmodule and web module.
The problem now I am facing is that cedapi is not getting recognized by ejb module or web module. But it is available in used dcs of each.

Compile error with IDLJ generated java files.

When compiling the IDLJ generated java files, javac is not able to recognize org.omg.CORBA.ObjectHelper
classs. Looks like the import is not finding this class.
I have located these classes in rt.jar but including this jar in CLASSPATH gives
a version '48.0' is too recent error.
Thanks
Ramesh

PLEASE IGNORE THIS MESSAGE. I HAVE RESOLVED THIS ISSUE.

How do I bundle my .java file as an .exe file to install from cd-rom

I have written a simple java application that I would like to lauch from cd-rom. I would like it to do the following:
1)Install the application to be ran locally on a client machine.
-OR-
2)Run the application from the cd-rom.
I think my code would have to be bundled and stored as an .exe file, but I'm not sure. I can not find any info on how to do this, so any direction would be greatly appreciated. Please explain in detail if you can, I am still new to this. Thanks!

1) I was able to use InstallAnywhere to create an installer for my application, but I was unaware that there was a java InstallShield. How do I access this feature?
2) Also from my understanding, I will have to write an executable java launcher in another language. Where can I find more info on this topic?
3) Not sure how to create jar files just yet. Where can I find more info on creating executable jar files.
Thanks for your help!!!!!!!

What is the best practise to provide a text file for a Java class in a OSGi bundle in CQ?

This is probably a very basic question so please bear with me.
What is the best way to provide a .txt file to be read by a Java class in a OSGi bundle in CQ 5.5?
I have been able to read a file called "test.txt" that I put in a structure like this /src/resources/<any-sub-folder>/test.txt from my java class at /src/main/java/com/test/mytest/Test.java using the bundle's getResource and getEntry calls but I was not able to use the context.getDataFile. How is this getDataFile method call to be used?
And what if I want to read the file located in another bundle, is it possible? or can I add the file to some repository and then access it - but I am not clear how to do this.
And I would also like to know what is the best practise if I need to provide a large data set in a flat file to be read by a Java class in CQ5.
Please provide detailed steps or point me to a how to guide or other helpful resources as I am a novice.
Thank you in advance for your time and help.
VS

As you can read in the OSGi Core specification (section 4.5.2), the getDataFile() method is to read/write a file in the bundle's private persistent area. It cannot be used to read files contained in the bundle. The issue Sham mentions refers to a version of Felix which is not used in CQ.
The methods you mentioned (getResource and getEntry) are appropriate for reading files contained in a bundle.
Reading a file from the repository is done using the JCR API. You can see a blueprint for how to do this by looking at the readFile method in http://svn.apache.org/repos/asf/jackrabbit/tags/2.4.0/jackrabbit-jcr-commons/src/main/java /org/apache/jackrabbit/commons/JcrUtils.java. Unfortunately, this method is not currently usable as it was declared incorrectly (should be a static method, but is an instance method).

Compiling the java file related to Servlet and Core java files in heirarchy

I am working in Jakarta-Tomcat 4.0.4 with j2sdk1.4.1_01 and i have put all servlet files in package "com.java.servlet"
and other core java files in package "com.java.action" . Also I am imorting java files in package
"com.java.action" to the package "com.java.servlet".
But when I am compiling the servlet files in package "com.java.servlet"
then the servlet files are not compiling because it cannot able to import
java files in package "com.java.action" . I have tried all the options.
If anybody has solution then please respond immediately.

I agree with the previous poster, this sounds like a generic compiling problem. FYI: I do not think that packages that start with "com.java." are special or reserved in any way.
You are making a servlet, not a JSP, right? Since this is merely about compiling, you might want to re-post to "Java Programming".

Error while compiling java file

Hi, im newby in java,
i was trying to compile java files, and after that i will use it in JSP as javabean.
I have 2 files already, the first file is a connection code, and its compiled successfully, it looks like this
i named this as ConnectionBean.java
package my_package;
import java.sql.*;
public class ConnectionBean {
     private Connection con;
     private static final String driver = "org.postgresql.Driver";
     private static final String url = "jdbc:postgresql://localhost:5432/PSQLDS";
     private static final String username = "postgres";
     private static final String password = "mypassword";
     public ConnectionBean() {
     public Connection logOn() {
          try {
               Class.forName(driver); con = DriverManager.getConnection(url, username, password); }
          catch(ClassNotFoundException e) {
               System.err.println("ConnectionBean: driver unavailable..."); con = null; }
          catch (SQLException e) {
               System.err.println("ConnectionBean: driver not loaded..."); con = null; }
          return con;
     public void logOff() {
          try {
               con.close(); }
          catch (Exception e) {
               e.printStackTrace(); }
as you can see above im using "package", and yes i have manage to put all my java files within the correct path (ROOT\WEB-INF\classes\my_package)
And also, i have test this class as javabean on JSP file and it works.
There for i continue to create the second java file, as a purpose to create a back engine for JSP. I use the same package as ConnectionBean.java, it looks like this
i named this as ListPageEngine.java
package my_package;
import java.beans.*;
import java.sql.*;
public class ListPageEngine {
     public static void main(String[] args) {
          ConnectionBean conBean = new ConnectionBean();}
on compiling process using command "javac ListPageEngine.java", i get this error message
ListPageEngine.java:11: cannot find symbol
symbol : class ConnectionBean
location: class my_package.ListPageEngine
ConnectionBean conBean = new ConnectionBean();}
^
ListPageEngine.java:11: cannot find symbol
symbol : class ConnectionBean
location: class my_package.ListPageEngine
ConnectionBean conBean = new ConnectionBean();}
^
2 errors
I think, i am pretty much sure that all my configuration (wheater its Apache TomCat, Environment Variable or PostgreSQL server) was good, as a prove, i was able to use ConnectionBean.class in my JSP file.
I susspect the problem is related with "package", seems i cannot use ConnectionBean class within ListPageEngine class when i use package.
For another information, i didn't install such thing as J2EE, i only install JDK 1.5, i also guess this might be the cause.
Right now im all stuck, i try to find thread which might be related with my problem but i failed to find it, most of them get the same answer by UncleSAM which are
Try the following forum (about JSP technology)
http://forum.java.sun.com/forum.jspa?forumID=45
JavaBeans spec contains nothing about JSP, but JSP spec describes using of beans.
i hope my question is clear so anyone who might have experience or clue with this problem might be able to help me.
Thanks before

finally folks, i found answer to my own problem hehehehe..
the problem is on the compiling command (javac ... my_file.java), i found that i need to add some parameter on the command to make it works.
This problem solved.

How to compile a java file in J9 for windows mobile 5.0

You can compile your source code using J2SE ;)
may be this is important for you:

Location of compiled java files

Where are the compiled java files for jsps? Sometimes I get jsp errors in the log
files like:
D:\jsrv\my\WEB-INF\_tmp_war_myserver_myserver_my\jsp_servlet\_mypage\_cancelmembership.java:105:
')' expected
However, the _cancelmembership.java file does not exist at that location. Only
the _cancelmembership.class file exists at that location.

You do NOT want to change the bundled CSS files. Create your own CSS and include it in the template after the built-in CSS include. Any classes you create in your own file of the same name and specificity as the built-in classes will override those classes. For example:<style type="text/css">
td.myclass{color:red}
td.myclass{color:blue}
</style>The color of the text in a table cell with the class "myclass" will be blue, not red, since the same class was defined twice, it will use the one that came last on the page.
If you change the classes in the built-in template CSS files, you'll change them for everyone using your APEX instance, which is not a particularly good thing to do.

Find out which java files really needed to compile

Hi,
I wan't to create WebStart jar files from a big library. Most times I only need a part of the lib (e.g. 30%). It is overhead to complie and pack the hole library.
I need a tool (favor for ant) - I can give a hand full of "initial java files" and it give me back a list of java files I have to compile and pack to run without ClassNotFound Exception.
This expects dynamic class loading.
Have you the same problem or solved this problem?
Using ant it is only possible to select a bundle of java classes and it is comiling exactly this classes :-/

You could use the verbose option while compiling. It will list the dependent source files that are required during compilation.
For command line, javac ... -verbose
From ant, you could specify verbose="yes" withing the <javac> task. :)

Applet.java file which used to compile, now does not

I cannot re-compile a java file which I used to compile many times.
It keeps saying:
error: cannot read PopupNavigatorApplet.java
1 error
I extracted the original from the archive - the same result
What might be wrong?

Perhaps you don't have the rights to access the file in the filesystem? Are you working on *nix or Windoze (or any other)? Is your classpath set properly (including the current working directory '.')?
So many questions and no answers.. ;o)

Error while compiling QuoteRenderer.java file

Currently I am working on Quotes customizations. As part of customizations, I need to modify the seeded java file (i.e., $JAVA_TOP/oracle/apps/qot/util/QuoteRenderer.java)

Error while compiling java file using J2SE 1.5.0

Dear Sir,
I'm getting the following error while compiling the java file.The code is also given.
package test;
public class TestRowSet {
public TestRowSet() {
"TestRowSet.java": cannot access java.lang.Object,bad class file: D:\Program Files\Java\jdk1.5.0\jre\lib\rt.jar\java\lang\Object.class,class file has wrong version 49.0, should be 48.0,Please remove or make sure it appears in the correct subdirectory of the classpath. at line 4, column 1
Please help me out.
--Suketu Naik.

But I'm compiling within "Borland JBuilder 9.0". I've
set the JDK path of the current project to point to
the path of JDK 1.5.0 . I've also tried to compile at
command prompt with "javac". I'm getting the same
error of "Undefinedclassloader" with long StatckTrace.
I don't know anything about JBuilder either. If you use the command prompt and enter the full path to the 1.5 javac.exe then that will prove whether the issue is using an older javac or not. For example "c:\j2sdk1.5.0_01\bin\javac HelloWorld.java"

How to compile a java file which is in memory?

how to compile a java file which is in memory?
such as:
String s="class MyClass {....}";
how to compile the string?
thx

come on ...That was a perfectly valid solution.
Do you know how to call the sun.* compiler? If not then search the forums for it. If that interface still exists (which it might not in newer versions) you then will create a string stream from your class and pass it to that.
