Com.sun.tools.javac.Main: method compile errors

I had a working web project the other day, and something happened that caused every page to start throwing this error:

I tried setting up a clean environment (server, EAR, web project), but haven't been able to re-solve the problem I had with the original project yet. If I could get a starting point to look for how to solve this type of error it would be greatly appreciated!

I checked my JDK compliance (1.4) and the installed JREs (Standard VM; WebSphere v5.1 EE JRE; C:\Program Files\IBM\WebSphere Studio\Application Developer\v5.1.2\runtimes\base_v51_stub\java\jre)

There is a bug in the compiler.
You would need to localize the problem to the source file, class and specific code. Once you do that you can file a bug but do not count on a fix without updating to 1.6. However locating it would allow you to modify the code to get around this problem.

I am using netbeans version 5.5 for this.
Although from the initial investigation I understand that this error is related to "jaxws-tools.jar".
However I could not resolve this error.
Can Somebody provide me with the steps to resolve this error.

No, I put the 'main' method just to see if it solved the problem

Use of classes in com.sun.tools.doclets

Hello -- What is the best practice recommendation wrt using the classes in com.sun.tools.doclets -- particularly with the planned refactoring?
I'm writing a doclet that doesn't subclass, say, the standard doclet. There are obviously several very useful classes in this package (ClassTree, Util, MethodFinder, etc.) that I'd like to use. I can simply call their methods, but I'm curious to know if their active days are numbered.
Would it be better to simply incorporate the source? What are the restrictions on using the source in my own doclet?
If this is all covered somewhere (I've been hunting around a bit), please feel free to simply point me to the info.
Thanks!
Steve

The Java 2 SDK license (which covers javadoc) allows you to only
redistribute the code unmodified.
In 1.5.0, the refactoring has renamed all of the packages and
moved a lot of code around. We hope and plan to release
the refactored code on java.net around the time 1.5.0 is
released, and get an early access of it out. We'll notify
people who are on the javadoc-announce email address which
people can sign up as described at:
http://java.sun.com/j2se/javadoc/#forum
If you want more specific information now about how these will change,
please let me know and we can answer those questions.

Sun Studio 11 f90 INTERNAL COMPILER ERROR: "FWOutput"

Hello SUN-Users,
I am new here, so I don't know I am right here!?
I have a w2100z with two opteron proc. With Sun Studio 11 I am trying to compile the new MUMPS (Ver. 4.6) package, but I get still the error message:
f90 -I/opt/mpich/include -Dpord -I. -I../include -c dmumps_ooc.F
1:LEN$1:1INTERNAL COMPILER ERROR near line 2494 in dmumps_ooc.F (phase FWOutput):
FWOutput: no visit function for class 'SubscriptTriplet'
*** Error code 1
make: Fatal error: Command failed for target `dmumps_ooc.o'
I search with google for "FWOutput" and I found out, that a similar problem already was recognized in Sun Studio 9 and fixed with the patch 115985-04 (6351156 f90 compiler internal error "FWOutput: no vist function for class 'SubscriptTriplet').
Here is some code near line 2494 from file dmumps_ooc.F:
      SUBROUTINE DMUMPS_614(id)
      I=id%MYID
      J=id%OOC_NB_FILES

      DIM_FILE=LEN(TRIM(id%DMUMPS_OOC_PREFIX))
    END SUBROUTINE DMUMPS_614The bolded line is the line 2494.
I can not see anything worng in this routine, but maybe I am already too tired for today.... :-)
Realy it is important to me to compile the MUMPS package,
so I hope somebody can help me?
****With best regards****

I think the TRIM should remove last character of the
string. (?)TRIM removes the trailing blanks in a string. String assignment then adds trailing blanks, so there's no point writing something like
s1 = TRIM(s2)
Can you say me where can I make a bug report? What is
to do?
Maybe next time I can do also a bug report?That's a good question. If you have a support contract, then you should be able to submit a bug report through that. Until recently, I believe that would have been the only way to do it. However, we now have an online support service:
http://developers.sun.com/developer_help/
I imagine you could get a bug filed through that channel as well.

Com.sun.security.auth.module.NTSystem compilation issues in Unix

Hi ,
I m using com.sun.security.auth.module.NTSystem in one my java application to get the current domain. The application and app server are running on windows OS.
Now i want to switch my OS to Unix, where i m getting compilation issues with com.sun.security.auth.module.NTSystem ,
1)Do i need to change the module from NTSystem to UnixSystem?
2) I m developing the java application in Eclipse 3.2 with java 1.4 , when i m trying to import the below statment com.sun.security.auth.module.UnixSystem i couldn't? Could you please let me how i can import the UnixSystem or NTSystem will work?
Appreciate your help!!!!

Unix, where i m getting compilation issues with com.sun.security.auth.module.NTSystemOf course.
Do i need to change the module from NTSystem to UnixSystem?Of course.

Com.sun.kvem.midletsuite.InvalidJadException: Reason = 13 error!

I get this error in WTK2.1 while trying to create package. Even the demos cannot be packaged.
The exact error is:
com.sun.kvem.midletsuite.InvalidJadException: Reason = 13
The file C:\WTK21\apps\photoalbum\bin\MANIFEST.MF is missing the required attribute: MIDlet-Name
The parameters are correctly set in Settings (the program above is a demo packaged with WTK2.1)
Any help is appreciated. I use Windows XP.

strange, check if the manifest looks like this one
MIDlet-1: PhotoAlbum,, example.photoalbum.PhotoAlbum
MIDlet-Data-Size: 256
MIDlet-Description: Photoalbum of images
MIDlet-Name: PhotoAlbum
MIDlet-Permissions: javax.microedition.io.Connector.http
MIDlet-Vendor: Sun Microsystems, Inc.
MIDlet-Version: 2.0
MicroEdition-Configuration: CLDC-1.0
MicroEdition-Profile: MIDP-2.0
if not, there is something wrong. These lines above are from my manifest and it works. Maybe you made some strange settings about the MIDlet-Name?

Overloaded method compile error

i have an inner class which has a method myMethod(boolean). the outer class also has a method of the same name (which the inner class's method overloads) myMethod( String, boolean ). if i try to call the outer class's method from the inner class, the compiler complains:
myMethod(boolean) in MethodTest.PrivateMethodClass cannot be applied to (java.lang.String,boolean)
it seems that the compiler doesn't realize that the outer method should be called, and is trying to use the inner one. naturally, if i change the name of the outer method, it works. is this a bug (which it seems like) or some "feature" of java?
here is the testcase code:
public class MethodTest
public boolean myMethod( String s, boolean flag )
    System.out.println( s );
    return flag;
private class PrivateMethodClass
    boolean value;
    public PrivateMethodClass()
      value = myMethod( false );
    public boolean myMethod( boolean flag )
      return myMethod( new String( "Inner myMethod" ), flag );
}

In particular, Java code can directly use all methods
of all current instances. Class scoping does not
influence overloading
The above does not apply since you are not overloading.
JLS Section 8.5 defines a member class declaration and refers to 6.3 for the scope. Section 8.1.5 says that if you use the same name in an inner class, the name is shadowed. 6.3.1 defines shadow-ing. Section 15.12.1 defines compile-time resolution of methods.
From these sections, it seems to me that your inner class method is shadowing the outer class method. Shadowing is different from hiding, overriding, or overloading. The compiler is not going to look for a method with a different number of parameters because you are not overloading. The compiler finds the myMethod in the inner class because the name matches.
A simple example of shadowing. Your code has the same issues with the added complexities of using an inner class and shadowing a method instead of a variable. public class Test {
     String v = "hello";
     public static void main (String[] args) throws Exception {
          Test t = new Test();
          t.myMethod();
          System.out.println(t.v);
     public char myMethod() {
          int v;
          v = 5;
          return v.charAt(0); //compile time error int can't be dereferenced

Re run the main method while error..

hi all
i got a class which i use to decode pdf to image
sometimes error happen(not all the time) ...and i dunno why it happens
in my desperate condition i'm thinking, what about if error happen then i try to re run the class
my questions are
1. is java capable doing this? is it using try catch?
2. how to re run the class?
anybody has useful link where i can dig some info of them or sample code, that willing to be post here?
thx in advance

public void doSomething(){
try{
    //something
}catch(Exception e){
    e.printStackTrace();
    doSomething();
}You should add a counter and only try a few times, otherwise you might run into an infinite loop with a out of memory exception.

Errors compiling Test.
How to solve this ?
Thanks,
/GFL

Yes. I know, because in another day I have used JDK1.5 in order to compile another application and it worked fine.
I have restarted the computer and now everything is ok . I do not know what the problem was.
Anyway thanks for your answer.

Deployment problem on WLS8.1sp3: com.sun.javac.Main not found

Hi,
I have a curious problem, after adding some simple (logging) code to an Session Bean, the EAR file will not deploy. I get the message below concerning compilation problems. If however I restore the Session Bean to the previous state, and having build a new EAR file, the erro persists. What is this strange behaviour, has this to do with weblogic settings for the EAR file of whatever ?
NB I also have tried to include the tool.lib jar in the projekt but that doesn't solve the problem.
Any help would be appreciated,

Urgent : Cannot Compile :Error :java.lang.NoClassDefFoundError: com/sun/too

I reinstalled win2k and since then I cant get my javac prompt to work
The error is :
Exception in thread "main" java.lang.NoClassDefFoundError: com/sun/tools/javac/Main
But I can find the java.exe
jar tools, etc.
Is there some version problems associated with this;
I am actually tring to run a compile script
as below:
COMPILE SCRIPT
rmdir/s/q K:\MyProjects\class\com
pause
javac -classpath K:\MyProjects\class;%JAVAC_CLASSPATH%%J2EE_CLASSPATH% -d K:\MyProjects\class @Compiler.txt
pause
This script was working normally before I reinstalled Win2k.
My CLASSPATH , PATH are below and my jdk is installed in K:\jdk1.3.0_02
SystemRoot = K:\WINNT
JAVAC_CLASSPATH:
%JAVA_HOME%\bin;%JAVA_HOME%\lib;%JAVA_HOME%\lib\tools.jar;%JAVA_HOME%\lib\dt.jar;
CLASSPATH
%SystemRoot%;%SystemRoot%\system32;%SystemRoot%\system32\cmd.exe;JAVAC_CLASSPATH% %J2EE_CLASSPATH%%JRE_HOME%; %MY_PROJECT%\SQLConstant.txt;
PATH
%SystemRoot%\system32;%SystemRoot%\system32\WBEM;%JAVAC_CLASSPATH%;%J2EE_CLASSPATH%;K:\Oracle\bin;K:\Program Files\Oracle\jre\1.1.7\bin;C:\Inprise\AppServer\bin;K:\Program Files\Sybase\SQL Anywhere 7\win32;K:\Program Files\Sybase\Shared\win32;K:\Program Files\Sybase\Shared\Sybase Central 4.0\java;K:\Program Files\Microsoft SQL Server\80\Tools\BINN;K:\Program Files\Sybase\EAServer4.0\java\lib\easclient.jar;K:\Program Files\Sybase\EAServer4.0\java\lib\easserver.jar;K:\Program Files\Sybase\EAServer4.0\java\lib\easj2ee.jar;K:\BorlandEnterpriseServer\bin;K:\WebSphere\AppServer\bin;K:\Program Files\IBM\MQSeries\bin;K:\Program Files\IBM\MQSeries\Java\Lib;K:\Program Files\IBM\WebSphere MQ Publish and Subscribe\bin
I cant notice any difference between the old classpath settings.
Could somebody help me out in this issue
Thanks
manoj

Hi Manoj,
I had the same problem.
This is what worked for me:
I'm running Win2k.
So, in C:\WINNT\system32 I found the following files
javac.exe
javaw.exe
java.exe
I removed them all, since I have the jdk pointed in the right classpath in my environment variables.
Once this was deleted. It worked fine!
I hope this helps.

I have installed OC4j.9.0.3 in my machine. I have already JDK1.3.1 installed in my machine.
I have written a CMP EJB. First time the EJB is deploying fine from Jdeveloper (9.0.3). When i change my EJB (i.e add some field in my EJB) and try to deploy OC4j.9.0.3 standalone server it is give following error.
An exception has occurred in the compiler (1.3.1_01). Please file a bug at the Java Developer Connection (http://java.sun.com/cgi-bin/bugreport.cgi). Include your program and the following diagnostic in your report. Thank you.
