IDEA 2.5.2 is the currently available released version.

IDEA 2.6 will support JDK 1.4 as a target development JDK (IDEA still requires JDK 1.3 to run).

Early Access of IDEA 3.0 is available at http://www.intellij.com/eap/.

This problem is described in the "KnownIssues.txt" file distributed with IDEA. This is a known issue of the Sun's JDK 1.3.1. To solve the problem, please add the "ulimit -s 2048" command to your startup script. By the way, according to the statistics, gathered from IDEA users, it is more stable under the IBM's JDK. And we also recommend using the KDE window manager.

To avoid class files in project views, you should not add the output path to the classpath manually, since it is already considered by IDEA automatically. Thus, just remove this entry from the classpath list.

Re: Well, it doesn't support the assert Statement!

Have you tried:
File | Project Properties | Compiler
Edit the text field labeled, "Additional javac command line parameters:" by adding the following:
-source 1.4
Be sure that you have set the target JDK as 1.4 prior to this. The IDE window will display "assert" in red because it is not yet aware of this new keyword. However, the underlying compiler is still just the Sun JDK. You have to tell the JDK to recognize assertions by using this flag even if you're not compiling via IntelliJ.

To avoid the console window when running IDEA, make the following change in the idea.bat file: instead of using java.exe, use javaw.exe.

Please note that running external tools or Ant scripts might open additional console anyway (if necessary), since they represent separate processes.

To get the above change to work I needed to make the above change from JAVA.EXE to JAVAW.EXE, so the line in my idea.bat looks like this: SET JAVA_EXE=%JAVA_HOME%\bin\javaw.exe

Also I needed to change the line that launches Idea (near the bottom of the bat) to add the Windows command START; so this now reads:

start %JAVA_EXE% %JVM_ARGS% <...> rather than

"%JAVA_EXE%" %JVM_ARGS% <...> This will quickly popup the cmd box which will promptly disapear, as a finishing touch the really fussy can now make a shortcut to modified idea.bat file and change its properties to start minimised.

Windows' start command
Author: Gabe Hicks (http://www.jguru.com/guru/viewbio.jsp?EID=715312), Jan 9, 2002

If you have java buried in a path with spaces, such as c:\Program Files\jdk1.3.1a, you will need to use the quotations around it as such "JAVA_EXE".

When start finds quotes for the first command, it assumes that it is a name for the application you are starting, not a path to it. To overcome this do the following:

start "IDEA 2.5" "JAVA_EXE" <...>
Re: Windows' start command
Author: Stephen Kingsland (http://www.jguru.com/guru/viewbio.jsp?EID=821443), Apr 2, 2002
Here's another way to handle spaces in your 'start' command line. Replace this, in idea.bat:

"%JAVA_EXE%" %JVM_ARGS% -Xbootclasspath/p:"%BOOT_CLASS_PATH%" -cp "%CLASS_PATH%" -Djdk.home="%JAVA_HOME%" -DCVS_PASSFILE="%CVS_PASSFILE%" %MAIN_CLASS_NAME% %*

with this:

set start=%JAVA_EXE% %JVM_ARGS% -Xbootclasspath/p:%BOOT_CLASS_PATH% -cp %CLASS_PATH% -Djdk.home=%JAVA_HOME% -DCVS_PASSFILE=%CVS_PASSFILE% %MAIN_CLASS_NAME% %*
start %start%

You remove ALL the quotes, and assign the command string to a variable, which you can then run. That way you don't have to worry about putting quotes around every use of an environment variable that could possibly have spaces in it.

The first change you have made is right. But to the second change make the following changes:
Your change looks like :
start "%JAVA_EXE%" %JVM_ARGS% <...>
It should rather be:
start %JAVA_EXE% %JVM_ARGS% <...>
The only difference is the quotation marks (""). Please remove it & try again. I am sure that will work out.

What is the difference between the Project view and the Source view? What directories should I add to the Project view and which ones to the Source view?

If your project contains Java source files, then you should add root directories corresponding to the default (unnamed) packages containing those files to the sourcepath.

For example if your class com.mycompany.mytool.MyClass is located in the "myproject/src/com/mycompany/mytool" directory, then you should add the "src" directory to the sourcepath. This way IDEA "knows" where it's supposed to find other classes given their fully-qualified names.

Project paths include any directories that contain files you intend to work with in your project. For example, you may add the "myproject" directory from the example above, so you will be able to browse various files, not only those located under the "src" directory.

The sourcepath may also contain paths to source files of any third-party library if you want to have those sources available for browsing.

Please also note, that different project-wide operations like compiling project, searching for usages and other will be performed on the files under the project paths only.

One way is to define the environment variable TOMCAT_OPTS, setting it equal to "-Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5000" You may then connect to tomcat using the remote debugger.

Running tomcat inside Idea (for servlet debugging)
Author: raj subramani (http://www.jguru.com/guru/viewbio.jsp?EID=576334), Mar 6, 2002

I got tomcat working through my Idea's IDE (from Intellij)

To acheive this:

  • Make sure the source code is present in your Tomcat installation dir (hereinafter referred to as TID and the Java Installation directory as JID).
    If you don't have it, get if from jakarta and install it in the TID.
    • The main class must be set to org.apache.catalina.startup.Bootstrap (you should see this once the source is added to your project path)
  • The VM parameters are set to:
    • -Djava.endorsed.dirs ="TID\bin;TID\common\lib"
    • -classpath "JID\lib\tools.jar;TID\bin\bootstrap.jar"
    • -Dcatalina.base="TID"
    • -Dcatalina.home="TID"
    • -Djava.io.tmpdir="TID\temp"
  • Program parameter must contain start

Finally make sure that you do not compile anything by setting the appropriate dirs in the "Compiler" option

PS: Make sure that the JID defined above and the Target JDK for your project are the same (I got an error when 1.3 was in the former and 1.4 was in the latter :-P )

Great info! It works!
Leave out the space in the VM parameters!

The VM parameters should be set to:
-Djava.endorsed.dirs="TID\bin;TID\common\lib"
-classpath "JID\lib\tools.jar;TID\bin\bootstrap.jar"
-Dcatalina.base="TID"
-Dcatalina.home="TID"
-Djava.io.tmpdir="TID\temp"

Here's a useful precursor to what has been written about this:

1. When Idea starts, create a project called tomcat. In the dialog prompting for a file name for the project, enter "Tomcat" for the name.

2. Change the project path to the directory where you installed tomcat

3. The sourcepath entries should all be ok (I haven't run into problems yet)

4. Change the classpath as you see fit.

All of the settings can go in the debug dialog (either hit the debug button or choose debug from the run menu)

What is the Commander for?

The two-panel Commander paradigm is a way of representing a hierarchy which provides the following benefits when working with the project elements:

1. In contrast to the tree-mode views, the Commander always shows only one level of hierarchy which is rather convenient in some cases (e.g. when you are permanently working only with one package and don't want or just don't need to view the whole hierarchy-tree)
2. It provides a very convenient interface for copying and moving packages/classes (i.e., when using copy/move operations in one of the two panels, the destination is automatically suggested according to the location currently expanded in the opposite panel).

Some more details on operations available from the Commander can be found in the popup menus that appear when you right-click on different nodes in the commander tree. These menus are context-dependent and allow different operations for the elements of different types.

It is not possible to associate *.java or *.jsp files in Windows so that they are automatically opened in IDEA, since IDEA is not just a java-file editor, but it is a project-based application. Thus, you can only associate the *.ipr (IDEA project) files with IDEA.

Noone wants to create a whole project for stuff like that.

Re: Associating *.java files in Windows
Author: Sean Shubin (http://www.jguru.com/guru/viewbio.jsp?EID=880048), May 15, 2002

I can see why the project-based nature of Idea makes this one difficult to implement. The problem is that many of Ideas features depend on having a valid project. Once a program trys to be good at two things at once, the design conflicts make it hard to be good at either one.

I think it is possible to get the best of both worlds by creating a special case project to handle individual files. For example, in addition to "Default Project Settings", have an item for "Absent Project Settings". Then working with individual files could behave something like this:

* Say the user double clicks on the file "C:\temp\MyClass.java"

* Idea scans MyClass.java and finds it is in the "com.mycompany.myproject" package

* Idea copies the file to c:\idea\no_project\com\mycompany\myproject\MyClass.java

* Now idea can use its project based features, from "Absent Project Settings".
Please add this feature

I would like to request this feature as well. Sometimes all I want to do is view or edit the source and use basic features such as in-file search, auto-indent, and color-coded source.

  3. Copy c:\idea.old\bin\idea.license to c:\idea\bin\idea.license
  4. Copy the entire contents of the c:\idea.old\config\keymaps directory to c:\idea\config\keymaps
  5. Copy the entire contents of the c:\idea.old\config\migration directory to c:\idea\config\migration
  6. Copy the entire contents of the c:\idea.old\config\options directory to c:\idea\config\options
  7. Copy the entire contents of the c:\idea.old\config\tools directory to c:\idea\config\tools
  8. Copy any user-defined templates in the c:\idea.old\config\templates directory (such as user.xml) to c:\idea\config\templates. Be sure to not just copy the entire directory, because you'll overwrite any changes IntelliJ may have made to the standard templates.

When I get a new zip file from IntelliJ, I open it, select all files *except* idea.bin (which I've heavily modified) and extract over the same directory - i.e. overwrite files. The ZIP doesn't overwrite preferences, settings, etc. so this is the quickest way to upgrade.

This is currently not possible. The next version of IDEA will provide a more flexible window configuration functionality.

Is there a way to see all files in the Project view ? Our project has .gif, jpeg, .pdf, and other file types but they are not shown in the Project view. Can I instruct IDEA to show all file types ?

Next version will support it. Currently, there is no way to let IDEA show binary files in the project views.

What is refactoring ? IDEA's feature list mentions 'refactoring'. What is it and where can I learn more about it ?

"Refactoring is the process of changing a software system in such a way that it does not alter the external behavior of the code yet improves its internal structure. It is a disciplined way to clean up code that minimizes the chances of introducing bugs. In essence when you refactor you are improving the design of the code after it has been written." Refactoring: improving the design of existing code / Martin Fowler (Addison-Wesley, 2000).

Mouse wheel handling Is it possible to enable mouse wheel handling with IDEA 2.5 under windows ?
I known that jdk 1.3 does not handle mouse wheel, but since I've seen a mousewheel.dll file in the idea/bin directory, I'm wondering if it is possible to use it...

Mouse-wheel in IDEA works only on Windows NT/2000/XP. It is not supported for Windows 9x.
 Comments and alternative answers

Mousewheel also works using Linux

It works fine for me under Linux, too. I'm running Mandrake 8.1, but I don't think that affects anything. I expect it will work for any distribution that works with a mouse wheel.
Mouse scroll wheel support in Linux, J2SE 1.4
Author: Colin Bennett (http://www.jguru.com/guru/viewbio.jsp?EID=500093), May 6, 2002
The scroll wheel support in MS Windows is done through a DLL and native code, which comes with the Windows version of IDEA. However, using J2SE 1.4, which provides scroll wheel support to all Swing applications, the scroll wheel works in Linux. J2SE 1.4 also has much, much better graphics performance, noticable in simple scrolling through a source file with IDEA, which is very smooth in 1.4. And the fonts look cleaner and crisper. The only problem is that as of now (6 May 2002) the latest versions of IDEA (codenamed "Ariadna", this is builds 600-620+) do not function with J2SE 1.4. Older builds, such as 545 ("Pandora") do still work. You will not get some of the new features, such as highlighting usused variables and methods. Feel free to encourage IntelliJ to switch to J2SE 1.4.
why not on win 9x ?
Author: Peter Schäfer (http://www.jguru.com/guru/viewbio.jsp?EID=905163), Jun 6, 2002
hm ... I've seen (and even written myself) Swing applications with mouse wheel support on Windows 9x.
So what's the reason why it isn't supported ?
How to implement Java application to recognize Mouse Wheel?
Author: Gamas Sugiarto (http://www.jguru.com/guru/viewbio.jsp?EID=910474), Jun 11, 2002
Hi, I am wondering how do you actually implement the Mouse Wheel listener in JDK 1.3.1_03, is that possible? How does Java utilize mousewheel.dll actually? Does mousewheel.ddl that resides in INTELLIJ_HOME/bin useable for the application that IntelliJ build or is it only useable for IntelliJ? Thank you very much.
mouse-wheel *should* work under win2000, but...
Author: Lars Luehn (http://www.jguru.com/guru/viewbio.jsp?EID=917352), Jun 18, 2002

I work with

  • IDEA 2.6 with
  • JDK 1.3.1 on a
  • Windows 2000 Server,
  • my mouse is a M$ IntelliMouse Optical with
  • the standard Windows drivers
but the mouse wheel support *normally* doesn't work. Actually, once or twice I had a working mouse-wheel (without me doing something special), but the rest of times I use IDEA it doesn't work.

Can I 'force' mouse wheel support somehow? How can I check where the mouse wheel stucks?

How do I get IntelliJ to generate serialVersionUID for me?

You can add an inspection warning that will then offer a prompt to generate. You can find the option several layers deep under Settings. Settings -> Errors -> Serialization issues -> Serializable class without 'serialVersionUID'

How do you turn off the use of CommandLineWrapper so that IntelliJ will include all your JAR files on the command line?

To do so, open the .iws file for the project and look for the line setting the dynamic.classpath property to true: 
<property name="dynamic.classpath" value="true"/>
With the project closed, edit the project file to set it to false: 
<property name="dynamic.classpath" value="false"/>
Then reopen project. Your runtime command line will no longer include CommandLineWrapper.
