Hot code replacement for local application?

i got hot code replacement working during debugging a removet web application (servlet). however, it doesn't work if i debug a simple (local) application. is there something i forgot to setup? (i'm using Eclipse)

This is an eclipse specific question. It is up to Eclipse to do the code replacement.
Have you tried 3.0-M8 ?

Hot code replace failed - Delete method not implemented

I debug my Java application with Eclipse (3.1). When I change my code during debugging, I get the following error message:
...MyApp at localhost:4540 (may be out of synch) was unable to replace the running code with the code in the workspace.
Reason:
Hot code replace failed - Delete method not implemented
What does that mean and how can I fix this?

This means you changed a class while it was debugging an application and it could not update the class for the application while it was running.
The error suggests you may be running an older JVM, i.e. pre-1.4.2 but this error can occur with any JVM if the change is incompatible with the previous version of the class.
The hot replace often does not work for non trivial changes to code.

Hot Code replace failed- VM inconsistent

When i am trying to deploy the application on WAS through NWDS, it is throwing Hot Code replace failed- VM inconsistent.
Please give your input.
thanks,

Hi,
> It ask me for SDM password, than it throws the error out.
I do not really understand why the SDM password should be checked for debugging...
(Double-)Check the WD-Debugging infos here: http://help.sap.com/saphelp_nw04/helpdata/en/cc/9cb34d9d11f74c98644df2b96b90f1/frameset.htm
And check for standard HotCodeReplacement issues this for example: NetWeaver Portal Debugging - 2, HotSwap your classes
Maybe putting this question within the WD forum could bring out more...
Hope it helps

Hot Code Replace Problem...

Hi Everyone,
I am using WebLogic 10 with Eclipse. Whenever i start the server in debug mode and make two three changes in the code... WHAM.... I get the Hot Code Replace error. Is there any way so that the server can keep up with the code changes. Publishing the app again takes approx 40 mins!

Almost always this is a limitation of the JRE/JDK you are using and really
nothing to do with Eclipse.
Try a different VM and see if you have better luck

Hot code replacement

How do I do hot code replacement in Eclipse? I tried to write another line while debugging the code, but I got the warning message about the obsolete methods in stack.

I didn't write a new method to replace a method.
Suppose that I have set a breakpoint at
System.out..println("hi"), debug it, and then change
the number 2 to 3 and save it, then I want this code
to work well. It did show a pop up dialog explaining
about obsolete methods.
What does it mean?
     public void testSomething() {
          System.out.println("hi");If you set a breakpoint here. This method was on stack and when you
did hot code replacement and this method "testSomething" becomes
obsolete method. And it will not execute the new modified statement.
To make the new replaced code to execute you should pop this
frame and continue. Or set a breakpoint at line before entering
this method and then do hot code replacement.
          System.out.println("2");
Thanks.

Hot code replace failed-VM may be inconsistent

Java HotSpot(TM)Server VM(micserver:50021)(may be out of synch)
was unable to replace the running code with the code in the
workspace
Reason:
Hot code replace failed-VM may be inconsistent
i face the following message and the code keep on retain to the old code.
this cause me have the debugging problem

Hi Yzme,
This happens since you save the changes to your code which is being debugged and your debugger session is still ON.
To avoid this close your debugger before making any changes to your code.

Replacement for LOCAL

Hi,
    I need the replacement for the keyword LOCAL......
some how i found the replacement (by my own) but it is not working properly...
the replacement is data declaration for the local...
Example program for local...
REPORT ZTEST_LOCAL_EXAMPLE.
DATA text TYPE string VALUE 'Global text'.
WRITE / text.          " Global text
PERFORM subr1.
WRITE / text.          " Global text
FORM subr1.
LOCAL text.
*data text type string.                     "replacement for local
text = 'Text in subr1'.
WRITE / text.
PERFORM subr2 USING text.
WRITE / text.
ENDFORM.
FORM subr2 USING para TYPE string.
LOCAL para.
para = 'Text in subr2'.
WRITE / text.
ENDFORM.
Here it is local statement and the replacement statement... but the replacement is not working properly....
Thanks
vishnu. R

Output
Global text
Text in subr1
Text in subr2
Text in subr1
Global text
Output with replacement
Global text
Text in subr1
Global text
Text in subr1
Global text
Looks fine to me. What do you expect?

How to use Source Code Control for Large Application?

Hi, All!
I would like to collect knowledge about "best practice" examples for using Source Code Control and project organization for relative large application (let's say approx 1000 SubVIs).
Tools used:
LabVIEW 8.0
CVS Server
PushOK CVS Proxy Client
WinCVS
With LabVIEW 8 we can organize large project pretty well. This described in article Managing Large Applications with the LabVIEW Project.
I have read this article too: Using Source Control Software with LabVIEW In this Article Source Safe used, but with PushOK all looks nearby the same and works (some tricks for compare function are required).
Example. Two developers working together on same project. Internally project is modular, so one developer will work with module "Analysis", and another one with "Configuration" without interferences. These modules placed into Subfolders as shown in example above.
Scenario 1:
Developer A started with modification of module "Analysis". Some files checked out. He would like to add some SubVIs here. So, he must also perform check out for the project file (*.lvproj), otherwise he cannot add anything into project structure.
Developer B at the same time would like to add some new functions into module "Configuration". He also needed to check out project file, but this file already checked out by Developer A (and locked). So, he must wait until lvproj file will be checked in. Another way is mark *.lvproj files as text files in PushOK, but then one of developers will get conflict message by checking in and then merging will be necessary. This situation will coming very often, because in most cases *.lvproj file will be checked out all the time.
Question: Which practice is better for such situation? Is Libraries better than folder for large project?
Scenario 2:
Developer C joined to the team. First, he must get complete project code for starting (or may be at least code of one Library, which assigned to him).
Question: How it can be done within LabVIEW IDE? Or WinCVS (or other SCC UI) should be used for initial checkout?
Scenario 3:
Developer D is responcible for Build. Developers A,B,C have added lot of files into modules "Analysis", Configuration" and "FileIO". For building he need to get complete code. If our project splitted into folders, he should get latest *.lvproj first, then newly added SubVIs will appear in Project Explorer, then he should expand tree, select all SubVIs and get latest versions for all. If Project organized in Libraries, he must do the same for each library, isn't?.
Question: Is this "normal way", or WinCVS should be used for this way? In WinCVS its possible with two mouseclicks, but I prefer to get all code from CVS within LabVIEW IDE recursively...
That was a long post... So, if you already working with LabVIEW 8 with SCC used for large project, please post your knowledge here about project structure (Folders or Libraries) and best practices, its may be helpful and useful for all of us. Any examples/use cases/links etc are appreciated.
Thank you,
Andrey

Regarding your scenarios:
1. Using your example, let's say both developers checked out version 3
of the project file. Assuming that there are only files under the
directories in the example project, when Developer A checks in his
version of the project, there will be new files in one section of the
project separate from where Developer B is working. Developer B,
notices that there is now a version 4 of the project. He needs to
resolve the changes so will need to merge his changes to the latest
version of project file. Since the project file is a text file, that is
easy to do. Where an issue arrises is that after Developer B checks in
his merged changes, there is a revision 5. When Developer A and B go to
make another change, they get the latest version which will have the
merged changes to the project file but not the referenced files from
both Developer A and B. So when A opens version 5, he sees that he is
missing the files that B checked in and visa versa. Here is where the
developers will needs to manually use the source control client and,
external to LabVIEW, get those new files.
Where libraries help with the above scenario is that the library is a
separate file from the project so changes made to it outside of the
project do not require the project to be modified. So this time, the
developers are using a single project again which time time references
two libraries. The developers check out the libraries, make changes to
the libraries, and then check those changes in. So when each developer
opens the project file, since it references the project file, the
changes to the library will be reflected. There is still the issue of
the new files not automatically coming down when the latest version of
the library is obtained. Again, the developers will needs to manually
use the source control client and, external to LabVIEW, get those new
files. In general, you should take advantage of the the modularity that
libraries provide.
2. As noted in the above scenario, there is no intrinsic mechanism to
get all files referenced by a LabVIEW project. Files that are missing
will be noted. The developer will then have to use the source control
provider's IDE to get the initial contents of the project (or library).
3. See above scenarios.

How do I turn off hot key commands for the application menu/main nav?

(I am using Photoshop CC on windows 7 64bit)
I continue to have this problem which in many ways slows down my workflow. It is a bit difficult to explain so bare with me here.
When I am working through the different functions and tools like switching from the polygonal lasso tool to duplicating a layer and then nudging the image with the directional keys the application menu/main nav is selected instead of the designated hot key and I need to hit esc twice to exit the main nav selection and go back to the tool I was using... “I did say this would be hard to explain”.
Let me paint a specific scenario that causes this to happen:
I want to create a mirror reflection for a product. I first duplicate the product image, then I flip it vertically and drag it to the bottom of the base image. Then I hit the directional up button to nudge it into place but this doesn’t work because by hitting the directional button ‘File’ from the main nav is selected. In order to return to the ‘move tool’ I need to hit esc twice or hit the mouse button once. This may not sound like a big deal and it’s not but do this 500 times a day for a week with the ‘polygonal lasso tool or PLT’ and tell me it’s not a big deal after that. When using the ‘PLT’ you have no option but to hit the esc button twice because if you click the mouse button you place an anchor for the PLT and chance loosing anything you have already preselected with the PLT.
Anyway, moral of the story is... I have a mouse which is more than proficient in selecting File, Edit, Image, Type and any other main nav query. I would love the hot keys to select just the tools and simply leave the main nav out of it... when I first purchased CS5 this function was not apparent. It was only after an update or maybe I blindly changed a preference and poof... every second hot key I push I select something from the main nav which is a completely pointless and annoying function for me which I have never used and never ever will.
Please Adobe tech masters, help me! I will be forever in your debt.
Cheers,
Tony

Not a problem in the Adobe software. Something is wrong with your input devices or you have something on your system that instates global, system-wide shortcuts that may conflict with application specific ones. You need to figure out what it is.

Why would code work for an application but not an applet?

Hey there,
i'm trying to build a java ftp upload applet. I'm using the enterprisedt ftp class.
The code works fine when i run it as an application but not when i put it in the applet. The applet has been signed and is running off a plug in. I get no error messages, just nothing happens.
Would really appreciate some comments.
regards
hagen
the code
FTPClient ftp = new FTPClient("****");
ftp.login("user1", "***");
ftp.put("C:/INSTALL.log","test.log");

hi
im a manuel, from argentina
i would appreciate too much if you can give me that piece of code
i need for a site, an applet that could read files the visitor chosse from his pc and then upload that files to a server
is it possible?? you could help me ?
i think i need to sing my applet alright? how i do this? how it cost??
if anyone can give my a bit of code, to star�t programming, ill be very happy!

Disable Privacy Settings for Local Application

Hi,
Is there a configuration / policy file that can be used on a
user's local machine to disable the privacy settings dialog that
pops up asking "Allow / Deny" for a Microphone?
Our application is distributed on the client from an
installer that must be run with administrative rights, I need to
find a way to disable this from showing since the user is
implicitly allowing us access to their microphone; after all the
software is developed specifically for audio recording.
Thank you,
- Justin

Chris,
We learned that the Privacy tab (in Settings) can be found under the Flash plug-in for Firefox, but only if Firefox is running under an administrator.
Unfortunately, we haven't had much luck with the mms.cfg file. The following was used in the mms.cfg file (placed in both the %WINDIR%\SysWow64\Macromed\Flash and %WINDIR%\System32\Macromed\Flash” directories):
AVHardwareDisable = 0
AVHardwareEnabledDomain = local
AVHardwareEnabledDomain = 127.0.0.1
AVHardwareEnabledDomain = localhost
AutoUpdateDisable = 1
The AVHardwareEnabledDomain settings seem to be getting ignored regardless of whether the user is a standard user or an administrator. I also checked to make sure it wasn't just a local problem by going to a website that uses a microphone (http://www.testden.com/accent-reduction/systemcheck.htm). Adding the requested domain to the list (AVHardwareEnabledDomain = train.act360.com) still didn't bypass the allow/deny dialog box.
We know that the mms.cfg file is being read because setting "AVHardwareDisable = 1" will result in no prompt and that section being greyed out in Global Settings. I saw a post that suggested this setting was required to even make the AVHardwareEnabledDomain work, but it seems to block the local entirely and still brings up the dialog query on the internet site.
Thanks,
Torrey

Hotswap und Hot Code Replacement

I start a Java application which has a certain classpath in the start parameter -cp.
If a certain class has been loaded by that application, I cannot hotswap it. Why not? It seems that Java caches that class and uses it all the time, no matter if I replace it.
The only way for me is to stop the application and to start it again. But since it is a big application, this takes too much time. So I wanted hotswap for Java class files.
I don't need it for debugging. Just for normal development with Java 1.4.2.
Any idea how to solve it?

Another, more usually used, way to reload classes is using a custom classloader. I'd probably try to use a custom classloader rather than HotSwap if possible. I'm a bit unsure about using a debugging interface for doing production stuff. At least I'd first google to try to find success stories or examples of using HotSwap for that. Maybe I'm just a traditionalist scared of the new and unknown...
To reload classes loaded by a custom classloader, simply discard the classloader (stop having a pointer to it) and create a new classloader object. Google for "custom classloader" to find examples.

Code Review:: ADF BC applications

Hi,
We would like to know if there's any open source software available for code reviews of ADF applications and how to effectively use to for ADF BC applications?
1) Am I moving in right direction while exploring PMD and Checkstyle? Are these the right candidates for setting automated code reviews for ADF applications?
Is there a specific software recommendation by the forum members which can help me achieve this goal.
2) Can CodeCoach and Audit features available in JDeveloper help me in this?
3) Will I have to necessary create 'Custom Rules' for tasks like validating EO classes are not directly referred in the Controller? Are there some pre-built rule-sets available on this front?
4) Any other suggestions for ensuring better/faster code reviews not necessarily replacing the manual peer review process but reducing the unnecessary headaches that can be fixed by freely available software
Sid

I started using ADFLogger and added some log statements. When I ran my application in JDeveloper in Embeded OC4J server, these log statements are appearing in JDeveloper server log window. After I deployed this application to Oracle Application Server, these statements are not appearing in the application.log file and also not in any file. Am I missing any configuration setting? The log current level is INFO and I do have few INFO statements, SEVERE statements in my code. Thanks in advance.
