1131:Packages must not be nested
Hai all,
I m working on a Flex Application, in which I have to
communicate with the server through TCP Socket. I am using
XMLSocketClass. I got a code from help, but I am getting
"1131:Packages must not be nested" error whenever I m trying to
compile it. Pls tell me the reason for this error.

Thanks. No I am facing one more problem. I can't receive any
reply messages from the server, when I am trying to get some
responses through TCP Socket using XMLSocket Class.
addEventListener(DataEvent.DATA, dataHandler) is not working.. I
have posted the problem in the forum. Can u pls go through that??
Thanks in advance,

Classes must not be nested??
I created a new Flash file (Actionscript 3) and typed this
code on the first frame on the movie:
class TestClass1 extends Object {
public function identify() {
trace('i am class one');
var obj:Object;
obj = new TestClass1();
obj.identify();
I get this error:
1131: Classes must not be nested.
What is going on?On publish, the compiler creates a class called MainTimeline
for all of the code in frames. By creating a class in a frame, it
is being nested inside the MainTimeline class... thus, producing
the error. -
[Solved] "source tarball may not contain nested subdirectories"
Hey guys,
I'm trying to upload (my first!) package to the AUR, however I'm getting the error "Error - source tarball may not contain nested subdirectories."
I've created the package using `makepkg --source`, it's just a single PKGBUILD file.
Running tar tvf looks fine:
$ tar tvf setcolors-git-0.0.0-1.src.tar.gz
drwxr-xr-x root/root 0 2013-08-17 08:25 setcolors-git/
-rw-r--r-- root/root 685 2013-08-17 07:19 setcolors-git/PKGBUILD
I searched around, but it looks like only a few people had this issue, and it was due to SELinx (which I'm not using).
I must be missing something really simple and I'm sure I'll feel dumb.
Here's the tarball in question.

Ahhh I get that too, your tar isn't the problem (I think), like mr. developer said, it's probably PHP5.5 that's the problem, it's the site.
My theory is that PHP5.5 probably upgraded their parsing stuffs and the site's code just isn't compatible yet. -
Hello - I must be missing something simple as I am totally unable to create packages and deploy them to our Creative Cloud for Team members.
From the reading I have done, the following seems to be correct, but I have had no success.
Create Package:
1. Clean install Windows 7 64-bit Sp1 on new hard drive.
2. Create local administrator on machine named "Builder" and Logon to Builder.
3. Logon to Creative Cloud as Team administrator, download and install CCP and logon as Team administrator
4. Cache preference set to default C:\Users\Builder\AppData\Local\Adobe\CCP\
5. Package details set to: name=Image; Save=C:\Users\Builder\Downloads\AdobeCloud; Named Licensing; 32-bit
6. Package configurations set to: Disable desktop app; ignore conflicts; disable update mgr; enable remote update; deploy to default directory
7. Select English (North America), Select Apps: Dreamweaver, Fireworks, Acrobat, Flash, Illustrator, InDesign, Photoshop
8. Packager starts at 7:25pm and completes with no error messages at 9:15pm (roughly 2hrs).
9. Image folder is about 5GB in size; Copy image folder to the \\NAS\ClientApps\Adobe folder on a network attached storage device.
Deploy Package:
1. Clean install Windows 7 64-bit Sp1 on new hard drive.
2. Create local administrator on machine named "Builder" and Logon.
3. Run a cmd session as administrator; map \\NAS\ClientApps to Z: drive, change directory to Z:\Adobe\Image\Exceptions
4. From cmd line execute ExceptionDeployer --workflow=install --mode=pre; completed without error displayed
5. Verified Adobe Acrobat XI Pro installed using control panel uninstall/change program
6. From windows explorer, navigate to \\NAS\ClientApps\Adobe\Image\Build and Run setup.exe as administrator
7. Progress bar gets just past half way, rolls back to no progress, and setup exits without error displayed
8. Verified no additional Adobe apps are installed.
9. Trying to run Acrobat causes an error message requesting an uninstall and reinstall Acrobat.
Any help would be much appreciated, as I am sure it is something simple I have overlooked.
Thank you,
KeithHi
EllenWeldonDesignLLC,
Deploying CCP package does not require installation of any other software. I have your log file and 1603 is the error what I see. 1603 is a generic error which is computer specific. Please go through the mentioned kb: http://helpx.adobe.com/creative-suite/kb/error-1603-install-cs3-cs4.html and try the steps and try to install again. Please do not run the msi but instead try to run the setup within the build folder as run as admin and let me know whether it worked. If still it rolls back enable hidden admin: http://www.howtogeek.com/howto/windows-vista/enable-the-hidden-administrator-account-on-wi ndows-vista/ and try installing again. Please let me know whether it worked.

please help!!. I cannot download the itunes 7.4.2 (?) i get the error
"this installation package could not be opened. Verify that the package exists and that you can access it, or contact the application vendor to verify that this is a valid windows installer package."
I am so frustrated. I tried everything and cannot download the new itunes. I got the new nano video and can't even use it!no, I never have resolved it. I spent 1 1/2 hrs on the phone with apple and couldn't figure it out. they finally said it must be something with my windows installer - but I have no problem downloading/installing any other programs.
go figure. -

FTPClient Package does not exist?
I have an FTP program. I'm trying to use this package. Here is a link to the class package overview:
http://www.enterprisedt.com/downloads/ftp/doc/com/enterprisedt/net/ftp/FTPClient.html
When I attempt to compile, I get the error that the package does not exist. I am importing these packages:
import java.lang.Object.*;
import java.lang.*;
// This package causes the error
import com.enterprisedt.net.ftp.FTPClient.*;
Is there something I need to download, or some other package to import?
Thanks,
LoganHi,
I finally found the ftp.jar and downloaded it and put it in the /j2se/jre/lib/ext.
I can now compile with this import line:
import com.enterprisedt.net.ftp.*;
Now my problem is trying to get this to work:
String server = "192.168.1.100";
String user = "logan";
String passwd = "passwd";
try {
FTPClient ftp = new FTPClient(server);
} catch (IOException ex) {
System.out.println("Caught exception: "+ex.getMessage());
But I get this error when compiling:
unreported exception blah blah must be caught or declared to be thrown
Thanks.

[Java 7] Zip file system does not handle nested zip files
The ZIP FileSystem which is shipped as an extension with Java7 does not support nested ZIP files. I.e., you can open the outer zip file as a FileSystem, but if you try to open an inner zip as a FileSystem, you get this exception:
java.nio.file.ProviderNotFoundException: Provider not found
at java.nio.file.FileSystems.newFileSystem(FileSystems.java:403)Since the ZIP FileSystem is an extension, and not a part of the core JDK, I'm posting this here (and on Xueming's blog) in the hope that it will get resolved. It doesn't seem right to report it as a JDK bug.872883 wrote:
The zip file system definitely allows zip entries to be read without extracting them first. And--based on reviewing the ZipFS source code that Oracle has included with the JDK--it doesn't appear to be silently extracting the data to a temporary file.you missed the point of what Peter Lawrey said. in order to create a ZipFS on a zip file, it must be a file in the first place (i.e. have random access). there is no way to do random access on an entry within an existing zip file, therefore in order to create a ZipFS on a nested zip file, you would first have to extract it to a file. -

hello people,
i am try to create a package using java program.
tha file is compiling .
class file is created
but it os stored in the same folder where i have stored the java file.
package is not created.
i am pasting my java code below
plz help me
thank u
package javaprog;
public class first
private String swa="chaithu";
private String swa1="schaithu";
private String n;
public String value()
n=swa+swa1;
return n;
public void setting(String a,String b)
swa=a;
swa1=b;
is there any modifications in the program or shall i dont any configural changes in the system.
thanks in advance.thats ok boss
but if u specify
package javaprog;
the package(folder) has to be created and the class
file is supposed to created in that folder
right !
if not
what is the nessicity of using package statement in
the java programing.No, that's not quite right. The class file will always be put into the same directory it's source file is in, UNLESS you specify otherwise.
When the directory DOES matter is when you link it into an application (on the class path). Here, you specify the directory that the base package is in, and the classes must be in appropriate directories beneath that base directory in your classpath.
So javac does not actually generate the directory structure necessary for your packages to be linked into an application or a compile - it just puts the classes where the source files are. BUT, if you put your source files in the correct package directories before compiling, then when the class files are output, they will automatically be in the right places, by virtue of the fact that the source files were in the right places.

Clients getting Applications and Packages, but NOT Software Updates
I am trying to set up a new SCCM2012 installation and have come across a strange problem that I need help on.
We have a single primary site at one location with distribution points at several other locations. Clients at some of the locations (but not all) are able to get deployed applications and packages from their DP, but for some reason are not able to get Software
Updates from the same DP.
When I look in the LocationServices log, I can see it contact the DP when an application is available. The following appear in the log:
Current AD site of machine is XYZ
Calling back with the following distribution points
Distribution Point='https://<My DP>...,Locality='LOCAL',DPType='Server',Version='7958', etc.
Calling back with locations for location request {<CID>}
But otherwise, the LocationServices log is filled with:
Current AD site of machine is XYZ
Calling back with empty distribution points list
Current AD site of machine is XYZ
I don't understand how the machine is able to locate and work with the DP for Applications/Packages, but not for Software Updates. I'm thinking it must be something with the boundaries/boundary groups, but I have checked and everything seems to be fine,
and they are working for Apps/Packs. The WindowsUpdate.log seems to indicate that it is talking with the MP:
**START** Agent: Finding updates [CallerId=CcmExec]
*Include potentialy superseded updates
*online=Yes;Ignor download priority=Yes
*Criteria="(DeploymentAction=* AND Type='Software') OR (DeploymentAction=* AND Type='Driver')"
*Search Scope={Machine}
+++++ PT: Synchronizing server updates +++++
+ ServiceId= {<CID>}, Server URL = <My MP with appropriate port>
Agent * Added update {<CID>}.202 to search result
* Found 289 updates and 77 categories in search; evaluated appl. rules of 2711 out of 4339 deployed entities
** END ** Agent:Finding updates [CallerID=CcmExec]
But there is no mention of my DP. -
Ocs package does not match the current software components
Hi Experts,
In our SAP ERP 6.0 system few components like SAP APPL,EA APPL ,FinBasis were already upgraded to 603 SP04 long time back.
Now to install language,we need to upgrade all the components to EHP3.The pre requisite to upgrade to EHP3 as per note number 1095233 is SP08.Few of our components are at SP06 level and i downloaded the supported packages of all the components to upgrade to SP08 and then upgrade to EHP3.
When i try to display/define the component ECC-DIMp,i get the eror message message" ocs package does not match the current software componentu201D when trying to apply ECC-DIMPu201D .When i looked at the queue,the SPAM is looking for prerequisites of components EA APPL 600 and SAP APPL 600(This components are already upgraded to 603 level).
Please suggest me the option.
Thanks
satishHi,
For your problem, please check SAP note 1083533, please check extract from this note:
If you cannot integrate the required component Support Packages because the import conditions are not met (for example, because you have already installed SAP_APPL 603 although SAP_APPL 600 is the prerequisite), you must update the import conditions. When you try to install EHP3 packages using the EHP installer (EHPI), the following error occurs in SPDA_EHP_INCLUSION.LOG: "OCS package SAPKxxx does not match the current software component vector" Ths system displays the same error message when you try to install packages using transaction SAINT. Proceed as described in Note 1118803.
Solution is documented in the SAP note 1118803.
Thanks

Import statement reports 'package does not exist'
I am seeing another odd error. I'm working on learning how to read and write to text files, and I have 2 errors reported, but one is obviously caused by the other. My package is labeled as such (copy>paste of package line):
package michaelchristopherp4db;
and the import line is this (copy>paste again):
import michaelchristopherp4db.ProductRecord;
However, Netbeans looks at the import and flags it red, saying package michaelchristopherp4db does not exist. this caused my line:
ProductRecord product = new ProductRecord();
to also be flagged in red as it cannot find the ProductRecord class. However, it has no problems with any of the product.get* method calls. Thank you in advance for any ideas or input.
here is the full code of the file reporting the errors.
