Too many jars
Hi, Friends,
For some good reasons, I received a lot of jar files (25) and I have to include them in my classpath.
Now I have a problem. When I use javac or ant, I got
The input line is too long.
The syntax of the command is incorrect.
I don't know if the only solution is to extract classes from those jars and put the class root location in the classpath. I don't like this solution.
Thank you for your help?

If your javac command line is too big then you can put your arguments in a file and run javac as "javac @argsFile"; as the list of jars is now in a file, you shouldn't get problems with the operating system's limit on command line length.
I'm not sure about ant but some make utilities have built-in functions to generate a "response file" which contains the arguments.

Too many jars cause the error "the input line is too ling"
Hi, Friends,

YoubinI did try using jre/lib/ext but it looked like I'd
have to put all the jars there -- i.e. even ones that
were in the classpath did not seem to be found unless
they were in the ext dirsctory. This may be a windows
quirk, but again, it is what I am stuck with for right
now.You mean that if you put one jar in lib/ext, then no jars outside of it are recognised? I've never heard of that before - it doesn't happen on any Windiws platform I've ever used.
I should warn you that I had a problem last week that seemed to come down to having unnecessary jar files in lib/ext - If you have an application that uses its own version of a particular jar, but there is a different version of the jar in lib/ext, the one in lib/ext is the one that gets used (I think its to do with class loaders deferring to parent class loaders) - not sure how often the problem occurs (I've never seen it before), but keep it in mind if you get any new problems coming up.
I don't know exactly what you're supposed to use lib/ext for, but I assume its intended as a place to put extensions to the core API and nothing else. -
"Too many open files" Exception on "tapestry-framework-4.1.1.jar"
When a browser attempts accessing to my webwork, the server opens a certain number of file descriptors to "tapestry-framework-4.1.1.jar" file and don't release them for a while.
Below is the output from "lsof | grep tapestry":
java 26735 root mem REG 253,0 62415 2425040 /usr/local/apache-tomcat-5.5.20/my_webwork/WEB-INF/lib/tapestry-portlet-4.1.1.jar

These unknown references are sometimes released automatically, but sometimes not.
And I get "Too many open files" exception after using my application for a few hours.
The number of the unknown references increases as I access to my webwork or just hit on "F5" key on my browser to reload it.
I tried different types of browsers to see if I could see any differences in consequence, and in fact it differed by the browser I used.
When viewed by Internet Explorer it increased by 3 for every access.
On the other hand it increased by 7 for each attempt when accessed by FireFox.
I have already tried optimizing the max number of file discriptors, and it solved the "Too many open files" exception.
But stil I'm wondering who actually is opening "tapestry-framework-4.1.1.jar" this many.
Could anyone figure out what is going on?
Thanks in advance.
The following is my environmental version info:
- Red Hat Enterprise Linux ES release 4 (Nahant Update 4)
- Java: 1.5.0_11
- Tomcat: 5.5.20
- Tapestry: 4.1.1Hi,
Cause might The server got an exception while trying to accept client connections. It will try to backoff to aid recovery.
The OS limit for the number of open file descriptor (FD limit) needs to be increased. Tune OS parameters that might help the server to accept more client connections (e.g. TCP accept back log).

How do i run a class which has too many dependencies/class/jar file
i am very new in java environment, i have developed a class which has to many jar file, it works fun when i run it from ide but problem arise which i wanna run it from command promt like
java classname
here is my code

so expert people , please help a novice people.
[codeIf you place all of your extra .jar files into a "lib" folder in same folder as your jar file then you can call the java class easily using a script similar to.....
#--------- runJava.bat file to call java program --------------------
cp=.
for f in lib/*.jar; do cp=$cp:$f; done
java -cp $cp:PROGRAM_JAR_FILE.jar com.myclass.mainclass
#--------- end script -------------
This loops over the *.jar files in the lib folder and adds them to the classpath. Please note that ":" is used as a cp seperator since this script was run on linux.

I am posting this in the '09 topic, but my question really dates back to Garageband '08. I rely on Garageband often, and I'm a big fan of it. However, it contains a serious problem which I need fixed.
I create a new project, drop a single iTunes song into it, and begin to edit. Almost every time, randomly while playing the song the "Part of the project was not played. This project has too many real instrument tracks to be played in real-time" warning message appears. I only have 1 track! Worse still, my audio driver lets out a terrible "HONK" which startles me and blasts through the entire house. After that, My sound output faintly exists until I open up Audio MIDI Setup and change a random setting on my output.
I am quite tired of this predicament. Is there anyway to fix this (without money)?I was experiencing a similar problem, and I just got off the phone with applecare and went through all their steps.
I'll try my best to recount them here. But before I do, let it be said that the tech fellow, once he heard what I was doing, exclaimed that my core problem was that I needed to be creating new projects, and not re-using the same project (ex. "My Song 2") over and over.
What I've been doing is backing up a pile of mini-discs that have live concerts on them. A couple of hours of audio each one, and I've been recording them into Garageband. After I divide the concert up into songs and export them to itunes, I've been deleting the track in Garageband and then importing the next concert (repeat x 10 concerts).
About 7-8 concerts in I started getting that popping sound when the sound would cut out (made the sound of depressing the safety-seal bubble on the metal lid of a jam jar). At first, quitting Garageband and opening it again would work. On the 10th concert, when the sound cut out the sound for the whole computer would stop working (itunes, volume buttons on my keyboard, everything).
So the tech fellow said the lesson is this: create new projects. Don't be shy about it. No need to re-use and recycle in cyberspace.
Now - my applecare steps:
- First we went: Macintosh HD, Library, then dragged "Caches" to the trash
- then went to Finder, Go, Utilities, Disk Utility, Macintosh HD, Repair Disk Permissions (that took some time)
- then restarted the computer
All seems to be well now.
Good luck -

AbhiPut only files which needs to be 'shared' ( e.g persistent store files for jms, jta transaction store etc) on the network drive .. put all other files including logs on the local disk.. see if that makes a difference..
NAS is slower than other storage setups like SAN and DAS... -
Hi All,
Need help from you all......I have run into lot of session beans... This is because I am developing an application where I extensively uses ValuechangeEvents.
In my application owing to ValueChangeEvents, a page normally gets refreshed more than one time and i need to get the values before the page refresh. So my backing beans are session scoped.
Following thread also talks about the same thing:
http://forum.java.sun.com/thread.jspa?threadID=705668&messageID=4364186
I get very similar NoSuchElementException as described in the link above .
Too many session beans per user will surely cause performance issues. Is this true?
A combination of session and request bean sounds good but it is not that straightforward. I cant keep on storing everything in the session bean common to all of my pages.
Please help and suggest some solution. Can I invalidate a session bean after the user moves to another page?
Please suggest.I am getting the following exceptions........does not seem to have changed much after doing saveState.Using tomahawk-1.1.6.jar

Dear All
We have a web application deployed on Rational Application Developer 6.0 (Operating System is Windows 2000 professional) our users are randomly getting java.io.IOException: Too many open files+ClassNotFoundException when they click on some servlet or jsp link, but they are getting this error randomly for example when they click some link they may get these exceptions but refreshing page or clicking once again on same link executes servlet successfully.If anyone could help on this topic we will be grateful
ThanksI think this these two exceptions are occuring in differrent environment

Too many Subscribers/Receivers for Queue
The link of Feedback in Java EE 5 tutorial doesn't work, because of this I ask my question here.
I have tried the " Simple Example of Synchronous Message Receives" in Chapter 32 of Java EE 5 tutorial.
In case of destination type queue I got error message.
The log of test:
M:\java\javaeetutorial5\examples\jms\simple\producer\dist>appclient -client producer.jar queue 3
Destination type is queue
Sending message: This is message 1
Sending message: This is message 2
Sending message: This is message 3
M:\java\javaeetutorial5\examples\jms\simple\producer\dist>cd ../../synchconsumer/dist
M:\java\javaeetutorial5\examples\jms\simple\synchconsumer\dist>appclient -client synchconsumer.jar queue
Destination type is queue
Exception occurred: com.sun.messaging.jms.ResourceAllocationException: [C4073]:
A JMS destination limit was reached. Too many Subscribers/Receivers for Queue :
PhysicalQueue user=guest, broker=pc2900:7676(1442)
My question: How can I configure the Queue for more subcribers/receivers?Hi,
Depending on the version of JMS, this may be a limitation of iMQ PE Edition (This is early in the morning for me, I can't remember which one). So you can look at the documentation, this may be a limitation of PE versus SE or EE. If you can modify it it would be using either the command line imqcmd or the gui based, imqadmin. With it, you can get into the connection factory, and change the maximum number of active consumers onto the queue.
I beleive that using glassfish (as 9) would alleviate this limitation, if it is there, since this is using openmq (imq v4.0).

I'm Galit from the QE team of VIN.
All the things that you've described are correct.
It is actually an edge case where the only VM, that the manual App can be managed from its Map view, was removed from the App.
The Manual App management is as designed, and may be changed in the future.
There are 2 ways to overcome this situation:
1.You can, as you stated, create another Manual App with similar name and remain with the "Zombie App".
2. To run a specific command that will remove the Zombie App from the DB.
Please note that option no. 2 involves using an API that we do not publish.
If you would like to use option no. 2 contact me in private and we will see about supplying the relevant commands to run in order to delete the "zombie" application.
Thanks,
Galit Gutman -
Router connection problems - DISH satellite receivers or too many devices?
(Sorry about that - I thought I had broken the message up.)
I'm having significant issues with my Linksys router timing out, and need help. I'll try to be as detailed as I can.
I have the following:
- Linksys WRT54G v3 wireless router I purchased off eBay 3-4 years ago. Using 128-bit WEP secirity. Even though the model says WRT54G, my Linksys setup page says I have a WRT54GL. Don't know if that's pertinent but thought I'd include the info)
- HP desktop running Vista Home Premium
- Gateway Solo laptop (circa 3Q 2002) running WinXP SP3, and also have WPC54G - Wireless-G Notebook Adapter
- Gateway M275 Notebook running Windows XP Tablet Edition w/SP3, internal wireless card
- Linksys WRE54G Wireless Range Expander, v3
My broadband internet connects to my cable modem, which then runs via ethernet to my router. I have my desktop connected to my router via (wired) ethernet cable (port 1), and the two laptops connect wirelessly. All three computers on my network run just fine and have had no connection issues until I had two (2) DISH satellite receivers installed this past Friday.
Prior to installation, I knew I would need the two receivers hooked up to my network via ethernet cable. Since one receiver was in the same room as my router, it was easy to run an ethernet cable from my router to the receiver (port 2). I had a challenge with the upstairs receiver, because I didn't have a direct connection, and wasn't sure how to wire it. So, I used my range expander by plugging in the expander into a nearby outlet, then connecting the receiver to the expander via ethernet cable.
I had some issues getting a good signal, and did some troubleshooting but made it work. Now I had five devices connected to my router: two with a wired ethernet cable and three wirelessly.
I started having connection timeouts within about 3-4 hours of satellite [receiver] installation. All of the sudden I couldn't connect to the internet on ANY device; both laptops couldn't connect wirelessly, my desktop couldn't connect, and the receivers were telling me my connection was bad. I checked modem but there were no issues. Still, I unplugged the power cable from the modem for a minute, then reconnected - still no internet. I called my cable company to have them troubleshoot the modem, but they pinged it several times & got positive results - still no internet, so I ruled the modem out.
I tried using the Windows connection troubleshooter to repair the problem, and got a DNS error message (which I don't know how to fix). I decided to unplug my router for 10-15 seconds, then plug back in - that got my internet connection going again. That lasted a couple hours & then failed. I unplugged the router again (is that a soft reset or a power cycle?), then reconnected & was able to connect to the internet. This happened a few more times over the weekend, and finally I decided the expander might be the issue (both DISH and Linksys tech support was not very helpful).
I found a way to wire my second receiver via ethernet cable (port 3), so now I had three wired devices, and two wireless devices. I thought this would fix the problem; it didn't, but at least I learned how to wire CAT5 cable. So I got that going for me... which is nice.
I plugged the ethernet cable directly from my modem to my desktop to test the timeout, but had no issues - the modem just wasn't the problem.
I was getting some IP address conflicts on my Norton Inernet Security, so I uninstalled that from my desktop, disconnected the power from the modem, disconnected the power from the router, shut down all devices, reset the IP addresses on the receivers, deleted the wireless connection from the laptops, shut down the desktop, and just left the whole mess alone for half a day. Then I reinstalled the Norton Internet Security, connected my wired devices, plugged the modem in, plugged the router in, reset my security, connected wirelessly with my laptops.
Within an hour my connection timed out.
Trying to chat with tech support wasn't feasible, as my connection kept going out. A guy at work said I shoudl ping my IP address, and let it repeat until my connection goes out. So I unplugged the router and plugged it back in to get an internet connection, the opened a cmd prompt and typed
ping 192.168.1.1 -t
I left it alone for a few hours, and when I came back, my internet connection was down, but I was still getting active pings - no problems there.
At this point I thought I had done everything except replacing my router (which I'm still tempted to do), but I called my broadband provider to see if there was anything they could do. One of the techs said I had too many devices connected to the internet, but I thought these routers were supposed to handle dozens of devices?
I finally called Linksys Tech Support and had a conversation for 90 minutes. We went through all the steps of unplugging the the modem, router & all connected devices, resetting the router, etc, etc. The only thing different he did was had me change my security from WPA to 64-bit WEP, and added passwords for DNA1 and DNS 2 (same password for each).
That was at 1:30am last night, and when I woke up to check my connection this morning, it was still connected. I have to check it again when I get home, but I'm wondering if I should just be prepared to get another router (and if so, any recommendations), or if there's something I'm still not doing that could resolve my issue - if I still have connection losses.
Also, I'm concerned about the security thing. If changing from WEP 128 or WPA to WEP 64 fixed my problem, I'm not sure I feel completely protected from intrusion - isn't that pretty much the least amount of security I can have (without forgoing it altogether)??
Finally, I've read a few threads suggesting possibly changing to static IP from DHCP; however, my satellite receiver installation documentation specifically advises against this for the receivers.
Anyway, I would very much appreciate some help.

Too many connections - even after closing ResultSets and PreparedStatements
I'm getting a "Too many connections" error with MySQL when I run my Java program.
2007-08-06 15:07:26,650 main/CLIRuntime [FATAL]: Too many connections
com.mysql.jdbc.exceptions.MySQLNonTransientConnectionException: Too many connections
at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:921)
at com.mysql.jdbc.MysqlIO.checkErrorPacket(MysqlIO.java:2870)
at com.mysql.jdbc.MysqlIO.checkErrorPacket(MysqlIO.java:812)
at com.mysql.jdbc.MysqlIO.secureAuth411(MysqlIO.java:3269)
at com.mysql.jdbc.MysqlIO.doHandshake(MysqlIO.java:1182)
at com.mysql.jdbc.Connection.createNewIO(Connection.java:2670)I researched on this and found out that I wasn't closing the ResultSet and the PreparedStatement.
The JDBC connection is closed by a central program that handles connections (custom connection pooling).
I added the code to close all ResultSets and PreparedStatements, and re-started MySQL as per the instructions here
but still get "Too many connections" error.
A few other things come to mind, as to what I may be doing wrong, so I have a few questions:
1) A few PreparedStatements are created in one method, and they are used in a 2nd method and closed in the 2nd method
does this cause "Too many connections" error?
2) I have 2 different ResultSets, in nested while loops where the outer loop iterates over the first ResultSet and
the inner loop iterates over the second ResultSet.
I have a try-finally block that wraps the inner while loop, and I'm closing the second ResultSet and PreparedStement
in the inner while loop.
I also have a try-finally block that wraps the outer while loop, and I'm closing the first ResulSet and PreparedStatement
in the outer while loop as soon as the inner while loop completes.
So, in the above case the outer while loop's ResultSet and PreparedStatements remain open until the inner while loop completes.
Does the above cause "Too many connections" error?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The following is relevant sections of my code ( it is partially pseudo-code ) that shows the above 2 cases:
init( Connection jdbcConnection ){
String firstSQLStatement = "....";
PreparedStatement ps1 = jdbcConnection.prepareStatement( firstSQLStatement );
String secondSQLStatement = "....";
PreparedStatement ps2 = jdbcConnection.prepareStatement( secondSQLStatement );
String thirdSQLStatement = "....";
PreparedStatement ps3 = null;
ResultSet rsA = null;
try{
ps3 = jdbcConnection.prepareStatement( thirdSQLStatement );
rsA = ps3.executeQuery();
if( rsA.next() ){
rsA.getString( 1 );
}finally{
if( rsA != null )
rsA.close();
if( ps3 != null )
ps3.close();
//Notice, how ps1 and ps2 are created here but not used immediately, but only ps3 is
//used immediately.
//ps1 and ps2 are used in another method.
run( Connection jdbcConnection ){
ResultSet rs1 = ps1.executeQuery();
try{
while(rs1.next()){
String s = rs1.getString();
ps2.setString(1, s);
ResultSet rs2 = ps2.executeQuery();
try{
while(rs2.next()){
String s2 = rs2.getString();
}finally{
if( rs2 != null )
rs2.close();
if( ps2 != null )
ps2.close();
}catch( Exception e ){
e.printStackTrace();
}finally{
if( rs1 != null )
rs1.close();
if( ps1 != null )
ps1.close();
//Notice in the above case rs1 and ps1 are closed only after the inner
//while loop completes.
}I appreciate any help.Thanks for your reply.
I will look at the central connection pooling mechanism ( which was written by someone else) , but that is being used by many other Java programs others have written.
They are not getting this error.
An addendum to my previous note, I followed the instructions here.
http://dev.mysql.com/doc/refman/5.0/en/too-many-connections.html
There's probably something else in my code that is not closing the connection.
But I just wanted to rule out the fact that opening a PreparedStatement in one method and closing it in another is not a problem.
Or, if nested ResultSet loops don't cause the problem.
I've read in a few threads taht "Too many connections" can occur for unclosed RS and PS , and not just JDBC connections. -
An embarrassment of riches - too many tablets! Should I consolidate and get an iPad Air?
Currently I have the following tablets:
- Nexus 7 2013 wifi only
- iPad 2 32 GB wifi + cellular, but no longer in contract
- iPad 1 wifi + cellular, no longer in contract
- an extra iPad 1, also wifi + cellular, not in contract that I got for free for helping somebody with some computer stuff
That same friend who gave me the iPad 1, wants to upgrade from his iPad 4th generation to an iPad Air, and he want to give me his 4th G iPad for free. It is a 64 GB wifi only model.
The reason I never upgraded beyond the iPad 2 was because all the later models got thicker and heavier, and I thought my iPad 2 was already too heavy, which is why I got my Nexus 7. I hardly touch my iPad 2 these days. They are both within arm's reach, but the Nexus 7 is easier to hold, and allows voice input, which I often find convenient, and most of the time I reach for it. I like the voice input on my iPhone 5 too, and I feel like something is "missing" when I pick up my iPad 2. Plus it feels like it weighs a ton next to the Nexus 7.
Well, anyway I have too many tablets. And soon I'll have the iPad 4th G. So I was thinking of selling the iPad 2, the two iPad 1s and the iPad 4 and getting an iPad Air, wifi + cellular with a data sharing plan with my iPhone 5. After all, compared to the iPad 2, the iPad Air is (1) lighter, (2) has Siri, (3) has a retina display, (4) has much better specs and (5) now the cellular model is universal, so if I take a trip to the U.S. it would be easier to use there.
Yet there are things I now prefer about my Nexus 7 with Android 4.4 over iOS 7. Like it has better sharing features, the ability to send all kinds of attachments, more customization, better "hooks" into the UI from 3rd party apps, the ability to choose your own default mail apps and browsers. It seems just more flexible overall. And the Facebook app runs "smoother" than on my iPad 2.
But I like iOS 7 too.
I wonder if I would use an iPad Air any more than I do my iPad 2 since it is lighter than the recent iPads. The screen being larger might make reading magazines and news sites easier. And Siri is still better than the Android voice dictation in my opinion. Or will the weight and size actually keep driving me back to the Nexus 7?
I guess I still haven't found the right place in my life for using a tablet for anything other than casual use. I don't want to get into a religious argument about whether tablets are production devices versus consumption devices, but basically I am in the camp that does not see them as true productivity devices. My iMac is for that.
Conundrums, conundrums. I do have too many "devices" right now though. Within an arm's reach I can count 12 computers, tablets and phones all on wifi! Who needs that much stuff?!
And if I do get the iPad Air, do I need 128 GB? The way they sell here in Japan, you don't put any cash down at all, and basically get an interest-free loan for 2 years. So "for just a few hundred yen more a month" you can go from the 32 GB model to the 64 GB model. And then "for just a few hundred yen more a month" you can go to the 128 GB model. It seems a waste not to get the 128 GB model. But in my current iPad 2 I only use a little more than half the current 32 GB.
Decisions, decisions. Any thoughts?
dougThe weight is somewhat of an issue for me. I find the iPad 2 irritatingly heavy whenever I pick it up, and the iPad 4th generation is heavier even than my iPad 2.
But for the amount I use it I could get used to that. That option is certainly the least headache, contract-wise, and I would avoid the ever-present possibility of dealing with AppleCare if something is "not perfect" (which it never is).
I guess the only "practical" reason would be that I would be getting rid of all my iPads with a cellular option. So if I did make a trip to the U.S. in the spring, it would be harder to use the iPad 4. Here, in Japan, of course I could use the free tethering option on my iPhone 5.
So I guess it is just the cellular option I'm giving up that is in the back of my mind.
