Problems to invoke java.exe from Java application, but ok for javac.exe??

How to invoke DOS application from Java application??
I try the following but it didn't work to invoke command prompt and java.exe, it
is working to invoke javac.exe. Any ideas why??
import java.io.*;
public class CallJavaTest
{ public static void main(String[] args)
{ try
Runtime.getRuntime().exec("C:\\WINNT\\System32\\cmd.exe"); //doesn't work!!
Runtime.getRuntime().exec("javac "+ "Test.java"); //it works!!
Runtime.getRuntime().exec("java "+ "Test"); //doesn't work!!
catch(IOException e)
System.out.println(e);

hi
String[] cmd = {"cmd","/c", "start",enteryourdoscommandhere};
Runtime rt = Runtime.getRuntime();
Process ps = rt.exec(cmd);
ps.waitFor();
int ev = ps.exitValue();
it works for my winXP.
hope it can helps and not too late ..

Slow starup of Java application - best practices for fine tuning JVM?

We are having problems with a java application, which takes a long time to startup.
In order to understand our question we better start with some background info. You will find the question(s) after that.
Background:
The setup is as follows:
In a client-server solution we have a win xp, fat client running java 1.6.0.18.
(Sun JRE). The fat client containt a lot of GUI, and connects to a server for DB access. Client machines are typical 1 to 3 years old (there are problems even on brand new machines). They have the client version of JRE - standard edition installed (Java SE 6 update 10 or better) Pretty much usual stuff so far.
We have done a lot of profiling on the client code, and yes we have found parts of our own Java code that needs improving. we are all over this. Server side seems ok with good response times. So far, we havent found anything about shaky net connections or endless loops in the java client code or similiar.
Still, things are not good. Starting the application takes a long time. too long.
There are many complicating factors, but here is what we think we have observed:
There is a problem with cold vs. varm starts of the application. Apparently, after a reboot of the client PC - things are really, really bad - and it takes (sometimes) up to 30-40 secs to start the application (until we arrive at the start GUI in our app).
If we run our application, close it down, and then restart
without rebooting, things are a lot better. It then usually takes
something like 15 - 20 sec. which is "acceptable". Not good, but acceptable,
Any ideas why?
I have googled it, and some links seems to suggest that the reason could be disk cache. Where vital jar are already in disk cache on th warm start? Does that make any sense? Virus scanners presumable runs in both cases.
People still think that 15 - 20 sec in start up on the warm start is an awful long time, even though there is a lot, a lot, of functionality in the application.
We got a suggestion to use IBMs JRE - as it can do some tricks (not sure what) our SUN JRE cant do concerning the warm and cold start problem. But thats is not an option for us. And noone has come up with any really good suggestions with the SUN JRE so far?
On the Java Quick Starter (JQS) -
improves initial startup time for most java applets and applications.
Which might be helpful? People on the internet seem more interested
in uninstalling the thing than actually installing it though?
And it seems very proprietary, where we cant give our Jar files to it?
We could obviously try to "hide" the problem in some way and make it "seem" quicker. Where perceived performance can be just as good as actual performance. But it does seem a bad solution. So for the cold start we will probably try reading the jar files and thereby have them in disk cache before startup of our application. And see if that helps us.
Still, ok the cold start is the real killer, but warm start isn't exactly wonderfull either.
People have suggested that we read more on the JVM and performance.
java.sun.com.javase/technologies/performance.jsp
java.sun.com.docs/hotspot/gc5.0/gc_tuning_5.html
the use of JVM flags "-Xms" "-Xmx" etc etc.
And here comes the question .. da da ...
Concerning various suggested reading material.
it is very much appreciated - but we will like to ask people here - if it is possibe to get more specific pointers. to where the gold might be buried.
I.e. in a an ideal world we would have time to read and understand all of these documents in depth. However, in this less than ideal world we are also doing a lot of very timeconsuming profiling in our own java code.
E.g. java garbage collection is is a huge subject - and JVm settings also. Sure, in the end we will probably have to do this all very thoroughly. But for now we are hoping for some heuristics on what other people are doing when facing a problem like ours..?
Young generation, large memory pages, garbage collection threads ect. all sounds interesting - but what would you start with?
If you don't have info to decide - what kind of profiling would you be running and then adjust what JVM setting in your trials?
In this pressed for time scenario. Ignorance is not bliss. But makes it hard to pinpoint the or those JVM parameters to adjust. So some good pointers from experienced JVM "configurators" will be much appreciated!
Actually, If we can establish that finetuning of these parameters is a good idea, it will certainly also be much easier to allocate the time for doing so. - reading, experimenting etc. in our project.
So, All in all , what kinds of performance improvements can we hope for? 5 out of 20 secs on the warm start? Or is it 10 % nitpicking? Whats the ball park figure for what we can hope to achieve here given our setup? What do you think based on above?
Maybe someone out there have done some finetuning of JVM parameters in a similiar PC environments like, with similiar fat clients...? Finetuning so and so - gave 5 secs. So start your work with these one-two parameters?
Something like that - some best practices? Thats what we are hoping for.
best wishes
-Simon

Thanks for helpful answer from both you and kajbj.
The app doesn't use shared network drives.
What are you doing between main starts to get executed and the UI is
displayed?
Basicly, Calculating what to show in the UI. Accessing server - not so much, there are some reads from a cache, but the profiling doesnt indicate that it should be a problem. Sure, I could shift the startup time to some other slot, but sofar I havent found a place where the end-user wouldnt be annoyed.> Caching of something would seem most obvious. Normal VM stuff >seems unlikely. With profiling i basicly find that ''everything'' takes a lot longer in the cold start scenario. Some of our local java methods are going to be rewritten following our review. But what else can be tuned?You guys dont think the Java Quick Start approach, with more jars in disk cache will give something? And how should that be done/ what does people do?I.e. For the class loader I read something about
1.Bootstrap class loader
2.Extensions class loader
3.System class loader
and is wondering if this has something to do with the cold start problem?
The extensions class loader loads the code in the extensions directories (<JAVA_HOME>/lib/ext
So, we should move app classes to ext? Put them in one jar file? (We have many). Best practice about that?
Otherwise it seems to me that it must be about finetuning the JVM?
I imagine that it is a question about:
1. the right heap size
2. the right garbage collection scheme
Googling heap size for XP
CHE22 writes:
You are right; -Xms1600M works well, but -Xms1700M bombs
Thats one best practice or what?
On garbage collection, there are numerous posts, and much "masters of Java black art" IMHO, And according to profiling GC is not really that much of a problem anyway? Still,
Based on my description I was hoping for a short reply like "try setting these two parameters on your xp box, it worked for me" ...or something like that. With no takers on that one, I fear people are saying that there is nothing to be gained there?
we read:
[ -Xmx3800m -Xms3800m
Configures a large Java heap to take advantage of the large memory system.
-Xmn2g
Configures a large heap for the young generation (which can be collected in parallel), again taking advantage of the large memory system. It helps prevent short lived objects from being prematurely promoted to the old generation, where garbage collection is more expensive.
Unless you have problems with pauses, try granting as much memory as possible to the virtual machine. The default size (64MB) is often too small.
Setting -Xms and -Xmx to the same value increases predictability by removing the most important sizing decision from the virtual machine. On the other hand, the virtual machine can't compensate if you make a poor choice.
The -XX:+AggressiveHeap+ option inspects the machine resources (size of memory and number of processors) and attempts to set various parameters to be optimal for long-running, memory allocation-intensive jobs]
So is Setting -Xms and -Xmx and -XX:AggressiveHeap
best practice? What kind of performance improvement should we expect?
Concerning JIT:
I read this one
[the impact of the JIT compiler is obvious on the graph: at startup the time taken is around 500us for the first few values, then quickly drops to 130us, before falling again to 70us, where it stays for 30 minutes,
for this specific issue, I greatly improved my performances by configuring another VM argument: I set -XX:CompileThreshold=50]
The size of the cache can be changed with
-Xmaxjitcodesize
This sounds like you should do something with JIT args, but reading
// We disable the JIT during toolkit initialization. This
// tends to touch lots of classes that aren't needed again
// later and therefore JITing is counter-productiive.
java.lang.Compiler.disable();
However, finding
the sweet spots for compilation thresholds has been tricky, so we're
still experimenting with the recompilation policy. Work on it
continues.
sounds like there is no such straigth forward path, it all depends...
Ok, its good, when
[Small methods that can be more easily analyzed, optimized, and inlined where necessary (and not inlined where not necessary). Clearly delineated uses of data so that usage patterns and lifetimes are apparent. ]
but when I read this:
[The virtual machine is responsible for byte code execution, storage allocation, thread synchronization, etc. Running with the virtual machine are native code libraries that handle input and output through the operating system, especially graphics operations through the window system. Programs that spend significant portions of their time in those native code libraries will not see their performance on HotSpot improved as much as programs that spend most of their time executing byte codes.]
I have the feeling that we might not able to improve performance that way?
Any comments?
otherwise i was wondering about
-XX:CompileThreshold=50 -Xmaxjitcodesize (large, how large?)
Somehow, we still feel that someone out there should have experienced similiar problems? But obviously there is no guarantee that the someone should surf by here!
In c++ we used to just write everything ourselves. Here it does seem to be a question about the right use of other peoples stuff?
Where you are kind of hoping for a shortcut, so you dont have to read endless number of documents, but can find a short document that actually addresses your problem ... well.

Windows xp runs java application but does not compile it - urgent please

Hi
My new PC(portable) does not compile my java progran:
'javac' is not recognized as an internal or external command, operatable program or batch file.
If you have any suggestion, please let me know!
Aria

Thanks anyhow;
The following information is sent to beginners site.
I have talked to british, belgian and others regarding this problem. They said it is very expensive and we laughed.
Hi,
Windows XP runs java application but does not compile it. I get following message:
'javac' is not recognized as an internal or external command, operatable program or batch file.
MS-DOS does not exists but a command line edits autoexec.nt having allinformation regarding installed jdk5. I run my java applicat
ion from here. But no compilation.
Environment variables has following information.
JAVA_HOME C:\jdk5.0

The following is working as a Java application but not as a DynPro App

Hello,
Please have a look at the following code:
URL testURL = new URL("http://<host>/error.txt");
HttpURLConnection c = (HttpURLConnection)(testURL.openConnection());
c.setDoInput(true);
c.setDoOutput(true);
c.setRequestProperty("Connection","Keep-Alive");
c.setRequestProperty("Proxy-Connection","Keep-Alive");
c.setRequestMethod("GET");
c.setUseCaches(false);
c.connect();
int cl = c.getContentLength();
DataInputStream dis = new DataInputStream(c.getInputStream());
This code is working well when I run it as an independent Java application but when I "plant" this code on a DynPro application I receive an I/O Exception at this line:
DataInputStream dis = new DataInputStream(c.getInputStream());
Can anyone please tell me why?

503 error means a bit different thing. See http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html
10.5.4 503 Service Unavailable
The server is currently unable to handle the request due to a temporary overloading or maintenance of the server. The implication is that this is a temporary condition which will be alleviated after some delay. If known, the length of the delay MAY be indicated in a Retry-After header. If no Retry-After is given, the client SHOULD handle the response as it would for a 500 response.
Note: The existence of the 503 status code does not imply that a server must use it when becoming overloaded. Some servers may wish to simply refuse the connection.

Can you track requests from both stand-alone Java and WD application via some HTTP tunneling tool to check differences in headers, encoding, etc?

Hi Gurus,
I have a problem. I'm riding the part of the JCO SERVER for SAP from sending information to a Java application.
I created the RFC destination of the type TCP / IP and I have registered my JAVA application in the visual administrator. This application java is already deployed listening to SAP and I can think of the following error when I run a BAPI created in the ABAP fate that I created.
It's not that I can think of that might be.
Or if someone was going another way of doing it from using sap we can send things to JAVA without having to java call the BAPI please help.

User Role problems in Sun Java Application Server Platform Edition 8

I am having two problems setting up user roles in Sun Java Application Server Platform Edition 8. At first, I thought that it was a problem with the higher level features that I was using, so I created a very simple example using the simplest authentication I can use, but the problem still occurs. I am using the file realm and configuring the users in the App Server Admin Console. I create 2 users in different roles. One user should have access, the other should not.
1) The first problem is that both users can access the page
2) The second problem is that the isUserInRole() method returns false for both users with the role that it should be authenticating against.
Here is a sample of my code:
Users Configured in Console:
username password roles
user1 ********** admin
user2 ********** noaccess
web.xml
 <security-role>
 <role-name>admin</role-name>
 </security-role>
 <security-constraint>
 <web-resource-collection>
 <web-resource-name>My Protected Area</web-resource-name>
 <url-pattern>/*</url-pattern>
 </web-resource-collection>
 <auth-constraint>
 <role-name>admin</role-name>
 </auth-constraint>
 <user-data-constraint>
 <transport-guarantee>NONE</transport-guarantee>
 </user-data-constraint>
 </security-constraint>
 <login-config>
 <auth-method>BASIC</auth-method>
 <realm-name>file</realm-name>
 </login-config>
 <servlet>
 <servlet-name>
 TestServlet
 </servlet-name>
 <servlet-class>
 mypackage.TestServlet
 </servlet-class>
 <security-role-ref>
 <role-name>admin</role-name>
 <role-link>admin</role-link>
 </security-role-ref>
 </servlet>
 <servlet-mapping>
 <servlet-name>
 TestServlet
 </servlet-name>
 <url-pattern>

 </url-pattern>
 </servlet-mapping>
TestServlet.java:
 out.println("admin role: " + request.isUserInRole("admin") + " ");
Thanks before hand for any responses.

Hi Jeanfrancois,
Your suggestion has lead me to find my problem. There were actually three problems.
1) First, you suggestion to reorder my xml file did not cause any errors to occur. I got suspicious that my web.xml file was wrong. I looked at some sample web-xml files and found that I was missing the header as follows:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app PUBLIC '-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN' 'http://java.sun.com/dtd/web-app_2_3.dtd'>
2) When I added this information, the deploy feature failed stating the my web.xml file was out of order. I fixed the ordering. It now deployed, but the security still wasn't working.
3) I then added the sun-web.xml file. This file was missing before hand as I thought it was unnessary. However, this file added the essential mapping from a role to a group. After adding this, it now started to work.
Thanks so much for you time and effort. You really did help me.

Hello John,
Thanks for the link. We have performed the steps in this blog:
1) Create DC Project "External Library" with name js/jars:
- Add *.jars in folder Libraries.[Screenshot Libraries|http://img846.imageshack.us/img846/8395/jsjars.jpg]
- Add archives (*.jar) to public part with name ExternalLib. Which option to choose?
a- Provides an API for developing/compiling other DCs (Option chosen)
b- Can be packaged into other build results (eg SDAs)
- Development Component -> Build
Step 1 is OK.
2) Create "J2EE Server Component / Library" DC with name js/lib:
- Add Used DC -> public part project ExternalLibrary -> "ExternalLib"
- Specify both build time and run-time dependency here and strong.
- Generated SDA file in <var>gen/default/deploy</var> How do we check that it contains <var>js.jar</var>?
- folder gen/default/plublic/defLib/lib/java then you meet *.jars files again. is OK.
- Development Component -> Deploy.
- Go to Visual Administrator. We found the library js/lib, but has no associated *. jar. It is the problem.[Screenshot Visual Administrator|http://img542.imageshack.us/img542/5537/visualadminlib.jpg]
3) Create "WebDynpro" DC with name pdf_jasper
- Add used DC (defLib) to WebDynpro DC with option "Build time".
- WebDynpro References -> Library references --> add <var>jslib
- Deploy
- Run error: java.lang.NoClassDefFoundError: net/sf/jasperreports/engine/JRDataSource

Error while invoking a Dataservice from client application

How to invoke a servlet from an application-URGENT

Hi,
 My requirement is as follows :
 I have to invoke a servlet from a client application. I am using
 java.net.URL and java.netURLConnection classes to
 open a connection and invoke the servlet.
 I am using WebLogic5.1
 my code snippet is as follows :
 URL url = new URL("http://localhost:7001/urlservlet");
 URLConnection connection = url.openConnection();
 connection.setRequestMethod("GET");
 connection.setDoOutput(true);
 connection.setDoInput(true);
 PrintStream outStream = new PrintStream( connection.getOutputStream() );
 outStream.print("message=hai");
 outStream.flush();
 outStream.close();
 When I execute the application, Webloigc server console is displaying the
 following line.
 <Listen Thread> Adding Address : <machine name><ip address>
 But the service method of servlet is not getting invoked at all.
 Help me to find the answer.

 If you want to send Java object you have to use POST:
 URLConnection conn = ...
 conn.setDoOutput(true); // makes this a POST
 OutputStream os = conn.getOutputStream();
 ...write your objects here...
 os.flush();
 os.close();
 InputStream in = conn.getInputStream(); // sends data to the server and
 // opens input stream
 ..read servlet response..

Problem while invoking ODI Scenario from BPEL

Hi,
I am trying to invoke a scenario from BPEL process through ODIPublicWebService.
When I initiate the process, its failing with following error message....
InvokeDeptAdmin_invokeScenario_OutputVariable>
-<part xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" name="part1">
-<ns1:invokeScenarioResponse xmlns:ns1="xmlns.oracle.com/odi/OdiInvoke/">
<ns1:Ok>false
</ns1:Ok>
<ns1:SessionNumber>23101
</ns1:SessionNumber>
<ns1:ErrorMessage>Agent didn't execute this command:
</ns1:ErrorMessage>
</ns1:invokeScenarioResponse>
</part>
</InvokeDeptAdmin_invokeScenario_OutputVariable
I observed that its failing as I am not giving any input to optional parameters like
<xsd:element name="SessionName" minOccurs="0" type="xsd:string" />
<xsd:element name="Keywords" minOccurs="0" type="xsd:string" />
<xsd:element name="Variables" maxOccurs="unbounded" minOccurs="0" type="VariableType" />
I can see following empty tags in my Audit of BPELConsole....
<SessionName/>
<Keywords/>
<Variables/>
And null is being considered as a variable by the Agent and following Exception is thrown in the Operator
java.lang.Exception: Specified variable not found in the Repository : null

Hi, how are you?
I did works including a parameter in my scenario and put value in this parameter on call scenario from BPEL. If i remove the parameter on the scenario and the call, its dont works.
Try include a parameter in your scenario.

Problem in invoking a servlet from another PC

hi
i am trying to invoke a servlet running on apache tomcat 5.0.28 from another PC, my j2me wireless toolkit is on one PC and it runs a MIDlet that invokes a servlet on another PC, but am getting an exception connectionNotFound....
both the computers are on LAN, what do i do?
Need guidance

No, i think tomcat server is enough.. have u checked your servlet from browser?
I got the same error in black berry application and at that time i found that its due to servlet config in web.xml
Have u configured your servlet in web.xml?
One suggestion.. change your URL to www.google.com and then run your MIDlet.. it confermed that your midlet is OK
Http request is fine to send data from your WTK.

Java works, but jar and javac don't

java at the command line works, but jar and javac don't
could it be the CLASSPATH
I'm running Windows if that helps. If you need more info ask away
Thanks

Definitely sounds like the classpath problem. From the sounds of the error message, you are using win95/98/ME, and so the best way to get around this is to set the classpath in your autoexec.bat file. I think the problem is because you have to set 2 variables in your path, one for the running of the java (JRE) and one for the tools to process the uncompiled files (SDK);
rightclick on your autoexec.bat and select Edit
here is my path, change yours accordingly so the paths lead to your windows, command and bin directories accordingly.
PATH=D:\WINDOWS;D:\WINDOWS\COMMAND;D:\PROGRAM FILES\JAVASOFT\J2SDK1.4\BIN
SET CLASSPATH=.;D:\PROGRAM FILES\JAVASOFT\J2SDK1.4\BIN\TOOLS.JAR
Theres a section on setting classpath in This site at :
java.sun.com/j2se/1.3/docs/tooldocs/win32/classpath.html
and if that doesn't work, then i recommend you download and IDE which sorts ou most of these problems for you, and makes programming much easier also :)
anything from:
Suns Forte
Jcreator
Jbuilder
to a real heavyweight which i use and find indispensible called Visual Age for Java, which is so powerful, but not for the faint hearted or weak-computered. :P
Good Luck

Code source works fine from console application but not from SharePoint interface

Hi;
Please can you help
me to understand why my code below works fine from console application (VS 2010) and not working from interface of my SharePoint collection site :
From console application : the subsite is created and I can to open without any problem
From Sharepoint GUI : the subsite is created but impossible
to open subsite : error 404 page not found ?
The subsite creation is very long (2 minutes) and in concole application When I try to open the subsite just after its creation I have page not found and I must waits (several refresh) more time to open the subsite correctly.
Can be I must to display a PoPup to show the progress creation ?
using System;
using System.Security.Permissions;
using Microsoft.SharePoint;
using Microsoft.SharePoint.Security;
using Microsoft.SharePoint.Utilities;
using Microsoft.SharePoint.Workflow;
namespace CreateSubSiteClients.EventReceiver1
 public class EventReceiver1 : SPItemEventReceiver
 public override void ItemAdded(SPItemEventProperties properties)
 base.ItemAdded(properties);
 try
 SPWeb web = properties.OpenWeb();
 if (properties.List.Title == "REFCLIENTS")
 SPListItem curItem = properties.ListItem;
 string name = properties.ListItem["SITE"].ToString();
 curItem["SiteUrl"] = web.Url + "/" + name;
 SPWeb rootWeb = web.Site.RootWeb;
 SPWebTemplateCollection webTemplates = rootWeb.GetAvailableWebTemplates(1036);
 SPWebTemplate webTemplate = null;
 String webTemplateName = "ModeleSiteCourrier";
 String webTemplateSearchName = "";
 for (int i = 0; i < webTemplates.Count; i++)
 webTemplateSearchName = webTemplates[i].Name.ToString();
 if (webTemplateSearchName.Contains(webTemplateName))
 webTemplate = webTemplates[webTemplateSearchName];
 break;
 SPWeb newSite = web.Webs.Add(name, name, name, Convert.ToUInt16(1036), webTemplate, false, false);
 newSite.Navigation.UseShared = true;
 newSite.Update();
 newSite.Close();
 Console.WriteLine("Le site suivant a été crée", name);
 catch (Exception ex)
 properties.Status = SPEventReceiverStatus.CancelWithError;
 properties.ErrorMessage = ex.Message.ToString();
 properties.Cancel = true;
Regards

Hi,
To create subsite using event receiver in SharePoint Empty Project, you can refer to:
Sharepoint 2010 event handler to create subsites
To display a PoPup to show the progress creation, you can use: MessageBox.Show("Hello, world.");
More information:
MessageBox.Show Method (String)
