Compile with 1.5.0 Run with 1.4.2 issue

Hi All
I compiled code with J2SDK 1.5.0 (or whatever it's called now) I then tried to run it on a JRE version 1.4.2.
It would not run, a long list of errors appeared.
Is it normal for this to happen?
To investigate I compiled the code with JSDK 1.4.2, that ran with no problems.
Any input appreciated
Thanks

Hi,
or try the RetroWeaver-Tool. You can download here:
http://retroweaver.sourceforge.net
-Martin-The problem with using the 1.5 compiler and e.g. RetroWeaver is not the generated byte code. The problem is that the compiler might match certain methods calls to methods which are new to Java 1.5. E.g. the class BigInteger has a constructor which only is available in JDK 1.5.

PL/SQL will compile with warnings but will not run

I have a pl/sql package that will compile with warnings but no errors but when i try to run it I get an ORA-6508 error telling me there is an error somewhere in the package but I can't find it.
I have two user schemas that use 2 slightly different versions of the package. I had to make slight code changes to one of the versions and when I made those changes it stopped running. The second version compiles and runs correctly.
After going through a line by line comparison the first copy was still not running. I copied the second version of the code into the broken schema and commented out the additional lines of code that are not needed in this version.
When I tried to compile and run this version it still fails with the same error.
I am using Oracle XE and the databases are small.
I can send on the code if necessary.
Can anyone point me in the right direction?
Thanks
Susan

I tried doing what you suggested but there are no errors as it is compiling correctly.
It is only when I run the package through the debugger that I get the error. I have posted it below

NoSuchMethodError compiling with 1.4 and running on 1.3

Hi community,
I have a little problem with code like the following when mixing both JDK versions:
StringBuffer sb1 = new StringBuffer();
sb1.append(new StringBuffer());In 1.3 this is linked to append(Object) and in 1.4 to the newly added append(StringBuffer) which does not exist in 1.3. The code compiles fine with both versions, but if compiled under 1.4 and run in 1.3 this throws NoSuchMethodError(as it should, of course).
I understand why it is so, the question is if there is an easy way to overcome this problem. I played with the target option of javac without success(javap shows it is always linked as stated), also I read a bit in the JLS to make sure I am right why the exception is thrown.
I see the following choices:
1. Compile with 1.3. Not a good idea because all other our products are developed and run in 1.4;
2. Ask the customers to upgrade to 1.4. There is some their reason for which they still stick to 1.3 and don't want to upgrade, we can't force them do it;
3. Find such places in code and explicitly cast. But who will know what other cases like the above exist in the code. I can find where append(StringBuffer) is used in the code, but what about other methods of other JDK classes? And it is a bad idea because somewhere in time it will anyway run with 1.4.
My question is if there is another easier option that I am missing at the moment.
Thanks for you time and cooperation
Mike

Why is option 1 bad? You will be able to run it in 1.4 even if you compiled it using 1.3, so I don't see the problem? It will never run in 1.3 if you can't compile it in 1.3.Because it will always be a source of errors. Always there will be someone that will not set up their project to use 1.3 for compile or will deconfigure it while working with the other projects. Besides that as I stated source compiles fine in both versions, I don't have a compiletime problem, but a runtime one.
I know this is the most reasonable option, I know what I would choose among the three listed above, I needed some confirmation if I have missed an option.
and you are correct about the target flagI only mentioned the target tag just as one of the directions of my search, we always whine for others not putting effort in their problems ;)
Thanks for opinions

Applet compiled with 1.4 not running in IE 6

I have a java applet when compiled with the 1.3 java sdk that came Oracle, runs correctly in IE 6. The applet opens a socket.
When I compile it using 1.4 java sdk from sun and run it in IE 6 it does not work.
When I installed the 1.4 SDK I selected to use it as IE's default java machine.
Note if I look in the internet options, settings, view objects it shows the 1.4.1 jre twice.
Note I can not remove the 1.3 jre that comes with Oracle as the installation is dependant on it.
The java classes included in my applet is
import java.net.*;
import java.io.*;
import java.text.*;
import java.awt.*;
import java.lang.Thread;
import java.applet.*;
I have the sdk bin directory early in the path and class path enviroment includes rt.jar from the 1.4 sdk.
I have even been into the reg and edited IE's classpath.
Anybody help, how do I know what jre, IE is using or why the applet won't run in IE6. Both versions run in Appletviewer.
Once I get this working I want to add javax and org classes to start passing XML over the socket anybody got advise on this also.

there are a couple of things to try with this. first is to try the class out with the java plugin enabled - this makes IE run the 1.4.1 VM, instead of the default 1.1 VM in IE. if this works, you probably have a version conflict in your code, and could try compiling with
'-target 1.1'
in your arguments. The problem I'm having is to do with finding the referenced classes in the applet. Try commenting EVERYTHING out of your applet (except 'init') and then running it. if the applet loads, the problem is that any class you try to instantiate inside the applet is not found by the browser. (NB you get the same error message with a version conflict as with a missing class file, very helpful...).
I'm not on this list much so if you want to talk more, or if you've solved this problem, please email me at [email protected]

An oci program compiled with oracle 9 run in a machine has oracle client 10

Hello,
I would like to know if an OCI program compiled with Oracle 9 client libraries can communicate with Oracle 9 and Oracle 8 database servers by using the oracle client 10 on Solaris? Is there any known problem of this combination?
Many thanks,

It largely depends on what your program does. If the program uses features which are only available in Oracle 9i and not in Oracle 8i then you are likely to get some errors. For the latter case, ie, compiling the program with Oracle 9 libs and runnig with Oracle 10 libs, talking to 9i server should be fine while 8i server may give you some unexpected behaviour.
Thanks,
Sumit

JDK 1.6 update n and compile with JRE

With the new optimizations of the install of a JRE with java 6 update n, is it possible to compile with jre and just the parts of the jre that you need for your application? That is can we distribute a java application that only have the parts of the JRE that it needs to a user that do not have any JRE isntalled and he can run it?
Thanks
WildChild

The license of Sun does not allow you to distribute just part of the JVM. The only solution to run your application in a computer without JVM is bundle your whole JRE folder together with your application.
At first it sounds bad, but if you use an installer to compress your files, the JRE will be around 14mb.

Regarding Automation Of The iOS App Compiled With Enterprise Program

Hi,
We have to automate the iOS app, compiled with `Enterprise Developer Account` build in `Adobe Flash Builder Environment`. We have checked the provision profile attached with the IPA file and the value of `getTaskAllow` is set to `False`, so it seems that the app is build with `Distribution Profile`.
As the app is developed from Enterprise Developer Account, so we are able to install and run the app in real device, but `Appium` as well as `Instruments` is unable to debug it and showing an error "Permission to debug <BUNDLE ID OF APP> was denied. The App must be signed with a development identity (e.g iOS Developer)".
So, is it necessary to build the app with `Developer Provisioning Profile` and mentioning the UDID of the device in the Development Provisioning Profile, so as to debug the app via `Appium` or `Instruments` ?

Yes. I can export Distribution certificates and Distrubution provisioning files and Flash will then export the .ipa file without issue. However when I go to install the app it seems to go over to the iPad and then I get a failure notice on the iPad. I am wondering if I am installing it incorrectly or if there is some step I'm missing. I am dragging the .ipa to iTunes to install it. If I export both the cert and the provisioning files as Development files the app goes on the iPad without issue, however it will expire in a couple of months so that is not what I want. I recently found this link http://www.adobe.com/devnet/digitalpublishingsuite/articles/distributing-enterprise-ios-vi ewer-apps.html which leads me to believe I have to distrubute the .ipa differently, however I was hoping someone had seen a similar tutorial for a Flash ipa. Or is this similar (or exactly) what I need to do?
Thanks so much for the reply.

I'm building it now, to test. I had to install icc manually because the AUR package for icc didn't work for me. I had to install icc manually (run the installer), but that wasn't enough. Before makepkg, you have to add the icc to $PATH e.g.
PATH=$PATH:/opt/intel/Compiler/11.1/064/bin/intel64
and execute iccvars_intel64.sh which is in that folder.

icc kernel compiles in similar time as gcc kernel, or if there any differences these may be negligible. To be honest I was not really interested in compiling times (was doing somethig else as it takes ~12 min on my system to finish kernel compilation), but rather with overall kernel performance. This is not the same as OS performance, but I am planning to compile firefox with icc and maybe some other stuff (if I am bored enough).
If you have 32-bit OS (I have no idea how it will work on 64-bit), try it. I can't post PKGBUILD for 32-bit icc kernel because I don't use PKGBUILD for kernels or nvidia as I have found it limiting/cumbersome/unnecessary (while PKGBUILDs work great for anything else on Arch).
The only part really annoying is intel server speed. Downloading icc sources (710MB for 32-bit only) tahes two hours. If you try to get 32/64bit sources even longer (1GB download).
32-bit icc PKGBUILD package requires only one modification related to Release Notes otherwise makepkg will fail. Once installed export icc path, edit kernel Makefile and change one line related to compiler: change gcc to icc. You can also add some compiling optimizations.
Pretty easy if you did compile kernel before.
note added:
actually combination of icc and zen seems to have nice effect on desktop responsiveness (this is 2.6.33)

Kaffeine embedded crash fixed when compiled with libxcb support?

From kaffeine website:
Embedded Kaffeine crash fixed.
This long standing bug is now fixed in current svn ...
In order to make it possible, we have ported Kaffeine and xine to xcb (a thread-safe replacement for xlib).
You can give it a try right now:
1) install libxcb=>1.0
2) install current xine-lib cvs (it contains xcb based video output plugins: xshm and xv)
2) install current Kaffeine svn
Notes
a) Both xine-lib and Kaffeine have to be compiled with xcb support (autodetected, check configure results).
b) Kaffeine will still work with xlib based video out plugins if compiled without xcb (but then, no fix!)
From 0.8.4 changelog:
* xine-part: support for xcb. Requires libxcb 1.0 and xine-lib 1.1.5. Fixes several issues.
Any reason not to incorporate this? If it lives up to it's promises It could mean kde users only need ONE media player :-) (I have 2 installed just to get DVD menus and embedding in konqueror without crashing)
Any thoughts?
Cheers,
Steve.

I felt that the laptop was possibly overheating and that is why I started down the road to call "customer support", thinking that a fan went out or there was damage to hardware due to it over heating. And that road got me no where in a fast manner, and two "techs" telling me it was a software related issue and that I needed to reformat the laptop (twice) and re-install to factory settings. Even when I did this, it still had the issue and they again told me that it was software related when there was no software on the computer except for Windows 7. The only thing that customer support helped me with is the knowledge of next time I buy a laptop, but Dell or any other laptop besides a Toshiba. That is too bad.
Anyway, I tried to continue on with my thinking of a possible over heating issue, so I blew air into the vents and fins of the laptop. A lot of dust came out. I kept blowing air into the vents until no more dust came.
My wife had to re-install everything again to her laptop after I got the major items re-installed. She has been running it for the last day or so with no issues. We hope that this was the issue. I know she enjoys the laptop when it was running well.
I guess we will see how it goes.

Bad performance of PARI when compiling with GCC for SPARC 4.2.0

Hi,
I've compiled pari (2.3.3) with gcc 4.2.0 and with an old gcc 3.3.2 on a Sun Fire V240 and Solaris 10.
The performance of pari compiled with gcc 4.2.0 is terrible. I've tried it with '-O3 -fast' and without this flags with the same result.
First compiled with gcc 3.3.2 without any special CFLAGS and run make bench:
* Testing objets for gp-sta..TIME=4 for gp-dyn..TIME=4
* Testing analyz for gp-sta..TIME=82 for gp-dyn..TIME=80
* Testing number for gp-sta..TIME=63 for gp-dyn..TIME=62
* Testing polyser for gp-sta..TIME=19 for gp-dyn..TIME=19
* Testing linear for gp-sta..TIME=30 for gp-dyn..TIME=29
* Testing elliptic for gp-sta..TIME=50 for gp-dyn..TIME=51
* Testing sumiter for gp-sta..TIME=45 for gp-dyn..TIME=47
* Testing graph for gp-sta..TIME=25 for gp-dyn..TIME=25
* Testing program for gp-sta..TIME=94 for gp-dyn..TIME=94
* Testing trans for gp-sta..TIME=228 for gp-dyn..TIME=225
* Testing nfields for gp-sta..TIME=434 for gp-dyn..TIME=433
+++ Total bench for gp-sta is 726
+++ Total bench for gp-dyn is 722
Then compiled with gcc 4.2.0 again without any special flags and run make bench:
* Testing objets for gp-sta..TIME=4 for gp-dyn..TIME=4
* Testing analyz for gp-sta..TIME=82 for gp-dyn..TIME=83
* Testing number for gp-sta..TIME=62 for gp-dyn..TIME=65
* Testing polyser for gp-sta..TIME=19 for gp-dyn..TIME=19
* Testing linear for gp-sta..BUG [1686975] for gp-dyn..BUG [1608146]
* Testing elliptic for gp-sta..TIME=50 for gp-dyn..TIME=52
* Testing sumiter for gp-sta..TIME=51 for gp-dyn..TIME=50
* Testing graph for gp-sta..TIME=28 for gp-dyn..TIME=28
* Testing program for gp-sta..TIME=98 for gp-dyn..TIME=97
* Testing trans for gp-sta..BUG [613000] for gp-dyn..BUG [606558]
* Testing nfields for gp-sta..BUG [3648091] for gp-dyn..BUG [3716170]
+++ [BUG] Total bench for gp-sta is 3029987
+++ [BUG] Total bench for gp-dyn is 2958336
Do anybody know this problem or can tell me what the problem could be?
Thanks!!
Rainer W.

Here are the compiler options I used to compile it with gcc4.
C compiler is /usr/local/gcc4/gcc/bin/gcc -O3 -Wall -fno-strict-aliasing -fomit-frame-pointer
Executable linker is /usr/local/gcc4/gcc/bin/gcc -O3 -Wall -fno-strict-aliasing -fomit-frame-pointer
Dynamic Lib linker is /usr/local/gcc4/gcc/bin/gcc -shared -mimpure-text $(CFLAGS) $(DLCFLAGS) -Wl,-G,-h,$(LIBPARI_SONAME)
If I use the -fast option I get the same result may be a little bit worse.
Here are some compilation lines:

Can I distribute the open source SWF compiler with my application?

I'm unclear reading the documentation if there is a difference between Adobe's official Flex SDK, and the open source version?
Can I distribute the open source SWF compiler with my application?
I have a flash application that users can change the fonts being displayed, if they supply the fonts in a compiled SWF. I found I can let the user select a font from their computer system, and using the mxmlc command I can easily generate a SWF with the font, which can be loaded by my application so the font will be part of the run time application when played on systems without that font already in the System fonts.
I was wondering if I could distribute the open source SDK so that I could compile these font SWFs for the user so they would not have to get involved in complicated Flash development. The audience is non Flash audience.
I tried using SWFMill but the fonts don't seem to work as they do with the mxmlc compile.
Thank you,
Scott Kerr

Moreover check also the compatibility of your open source license with MPL

Help compiling with .class files

I am using JGrasp and I am trying to compile a program that uses .class files instead of the .java files, but JGrasp will not recognize these at compile time. How do I get my program to compile with these .class files?

I prefer using Jenuity:
[http://www.nmmu.ac.za/jenuityIDE]
It's much simpler to use than JGrasp and isn't nearly as confusing.
For the record, you compile .java files into .class files. There is no need to "compile" existing .class files. If you have the class files you can run them from the command line. e.g. if you have a class file named Orange.class you should be able to type "java Orange" from the command line to run it. If Orange is inside a directory structure based on packages you may need to execute this command from just outside the 'highest" folder.
If you just need to link to these class files, copy them into the "/jre/lib/ext" folder of your JDK.

Can't compile with any layers hidden on timeline

Can someone explain what could possibly be going on?
Running CS4 I have a .fla that was compiling fine yesterday. Today I made some slight additions and it wouldn't compile, giving errors saying that various things were undefined. I was starting to go nuts until finally I made all layers in the timeline visible and compiled again. Now it compiles fine.
Just in case it was something Flash itself I created a new file, hid some layers and compiled and it was fine. So it's not the application, just this particular file.
What could be doing this? Why can't I compile with hidden layers?
Thanks for any help.

Hi fizbeam,
This happened to me a while ago!
It's annoying.. somewhere in the publish settings theres a checkbox marked 'dont export hidden frames' and if it's checked it'll cause this to happen.

Compiled with 1.5 and ran on 1.4

I compiled a program with Java 1.5, and when I ran it on an environment running Java 1.4 it gives me
java.lang.UnsupportedClassVersionError
What's the cause of this issue? And why can't it backward-compatible?
Is there a way to find out which version of Java a .class file is compiled with?

Is there a way to find out which version of Java a
.class file is compiled with?P.S. Yes, the version is encoded in the java class file. You can inspect the file using a hex editor, or write a program to dump them out (should be pretty simple).
See http://java.sun.com/docs/books/vmspec/2nd-edition/html/ClassFile.doc.html (specifically, minor_version, major_version). Note that the version number coded here is something other than 1.4, 1.5, etc... so you need to locate a reference which describes how these values correspond to actual JDK version numbers.
