Precompiled classes ignored on Solaris

I'm precompiling all of my jsps on NT and deploying them on Solaris. The
          classes seem to be ignored and the server always generates a new java file
          and compiles at runtime.
          I am using Weblogic 5.10 SP9. I have the following configuration
          case sensitivity is on during the compile, the correct case files are
          generated and used on NT
          the timestamps of the class files don't seem to matter
          pageCheck is -1
          Thanks
          Rob

          You must preserve the timestamps on the .jsp files between Solaris and NT. WL does
          not look at the timestamps on the .class files to decide whether or not to compile
          a jsp. It checks the date on the .jsp file against ... (the date on the .jsp file
          at the time it was compiled). Compile with -keepgenerated and look at the resulting
          .java file to see this.
          It also checks that it was compiled with the same version/service pack.

Precompiled JSP classes are ignored on Solaris

I'm using Weblogic 5.10 SP9, building on NT and deploying on Solaris. I
          precompile the JSP files but the classes are ignored on Solaris. I tried
          touching all of the classes to ensure that it is not a date issue but that
          didn't help. I also put the pageCheckSeconds to -1. I also use the
          weblogic.httpd.windows.caseSensitive flag and when the generated files are
          compiled they are placed in the same location with the same names and top
          level package.
          Thanks,
          Rob

Jar class path in solaris

Hi
I am new to solaris environment. I have a java file which is dependent on xerces.jar. to compile the file i need to set the classpath. pleas let me know how to set class path for xerces.jar which is in usr/raj/ folder structure of solaris machine.
if there is any on the fly method of setting classpath plz let me know....
thanks a lot
raj

What shell are you using?
csh: setenv CLASSPATH ${CLASSPATH}:/usr/raj/xerces.jarsh/ksh: CLASSPATH=${CLASSPATH}:/usr/raj/xerces.jar
export CLASSPATH

USB Video Class Driver on Solaris 10 and Sun Ray

Hello,
Is it posible to use the USB Video Class Driver (usbvc) on Solaris 10 and Sun Ray?
How can I do that?
Thank you very much.

It's not possible. The Video Class requires isochronous operation on USB and Sun Ray does not support isochronous mode.
Even if Sun Ray did support isochronous mode, the libusb library (which is what third-party applications use to interact with USB devices attached to Sun Ray) does not support isochronous transfers. The hard part is the Sun Ray itself. When that gets resolved it probably won't be very hard to add isoc support into libusb.

The File class ignores the file.separator system property?

I am saving the pathname of a file to a String using:
String pathString = myfile.getAbsolutePath();
This gives me e.g. "D:\Java\Projects\myfile.txt" on Windows XP
If I want to save this value to a properties file, then load it in a new invocation of the program, this string will not be recognised as a valid pathname because of the backslashes.
So I want to use forward slashes as the file separator char.
I tried:
System.setProperty("file.separator","/");
However, this setting seems to be ignored by the File class, as I still get the same string with backslashes from the getAbsolutePath() method.
Can anyone help please?

Yeah... I've used that before. Never recalled having problems. I can't, however, recall if there were file paths saved.
Just tested with this:
import java.io.*;
import java.util.*;
public class Props {
     public static void main(String[] args) {
          try {
               Properties p1 = new Properties();
               p1.put("file", new File("C:\\test\\Props.java").getAbsolutePath());
               FileOutputStream out = new FileOutputStream("Props.properties");
               p1.store(out, null);
               out.close();
               FileInputStream in = new FileInputStream("Props.properties");
               Properties p2 = new Properties();
               p2.load(in);
               System.out.println("p1: " + p1.getProperty("file"));
               System.out.println("p2: " + p2.getProperty("file"));
          } catch(Exception e) {
               e.printStackTrace();
}created this:

CSS Class Ignored

I'm trying to override the default css class for static styled text/message styled text/rawtext items by specifying a css class in the property pallette for these items.
When i run the page through jdeveloper it is not taking any effect.
I'vnt tried running it from the server.
I've tried with multiple css class types.
I've copied the blaf.css file from the server and placed in myhtml\OA_HTML\cabp\styles\
I've tried clearing the cache , deleteing the class files etc etc..
Any pointers ?
Thanks,
Tilak.

Tilak,
Following extract from Dev guide might be useful for your reference:
Using Styles
All of the regions -- and most of the items -- that you add to the page have their styles set automatically; you don't need to do anything extra (nor should you). As described above, you should be setting region and item properties ONLY if you must override the default behavior.
That said, there are several cases where you must set the CSS Class property for your items:
If you create a staticStyledText item to be used for instruction text, you must set its CSS Class to OraInstructionText.
For any text entry fields, checkboxes, poplists and radio buttons you must set the CSS Class to OraFieldText. Do not use OraPromptText for your radio buttons and checkboxes.
If you create a messageStyledText item for displaying read-only data, you must set the CSS Class to OraDataText for the data to render in bold (note that you don't need to set this value for table columns)
Tip: New OA Framework developers often make the mistake of trying to significantly change "native" component rendering by changing the CSS style. If you find yourself falling into this trap (and you're frustrated because your style settings don't appear to have any impact on the bean's runtime appearance):
Make sure you're using the right bean (region or item style) for the job.
If you're certain you're using the right bean, check to see if it publishes a method that lets you achieve the desired result. For example, an oracle.apps.fnd.framework.webui.beans.layout.OAHeaderBean inherits a setSize(int size) method that lets you control the size of the header text (which is useful when rendering headers in Home page "At a Glance" regions or in side navigation "Search" regions, for example). You cannot achieve this effect by trying to set the header's CSS Class to OraHeaderSubSub as some are tempted to try after reading the BLAF specification that the beans implement.

The admin/managed-server communication copies things to the managed server, which then always recompiles the pages when hit.
          This is a known issue and is fixed. The timestamps of the compiled classes was not being preserved when extracted from the war file used to distribute to the managed servers. This will be available in WLS6.1 Service Pack 3 - and there is a temporary patch available for SP2. Please ask your friendly BEA support person for it (you can refer to CR058946)
          I'd give you the patch myself, but they like to keep track of these things...

Solaris 10 zone configuration with sysidcfg and dhcp and hostname

Hi
Excuse me if I look like a n00b... it's probably because I'm a n00b.
I've been struggling in the dark for more than 2 days now and I'm wondering if I'm thinking about this all wrong...
I have stand-alone server where I need to run zones. I want to create zones and automagically configure them at boot (read: by running a script). So here's what I need...
A zone
starting from unconfigured state
whose hostname is not the same as the zone name
using corporate DHCP to get its IP address
with DNS config coming from the DHCP server
registering its address the DNS
with a preconfigured root password
(I don't own the corporate DHCP or DNS servers, I can't put my own DHCP or DNS servers on the network.)
I would lke to create the zone, throw some config at it, then boot the zone and walk away. I am using zones with exclusive-IP. I can construct the zones and manually configure them once they're started to have DHCP, my own name, registered IP address with DNS and everything else I have specified above. But I don't want to do it manually...
Sysidcfg seems to do some of what I want but not entirely.
In sysidcfg I can set the root_password, the primary interface using DHCP, DNS server. I can't set a hostname in sysidcfg AND use configure it for DHCP. So the hostname is not what I want it to be after the zone is started and ready to go. The DHCP server is providing the DNS configuration, Solaris does not seem to honour it, but i'll ignore that for the moment.
I have tried various combinations of using sysidcfg, /etc/nodename, /etc/hostname.+interface+ and /etc/dhcp.+interface+ but I can't find any combination that actually works.
I can write to the zonestorage/etc/nodename to set the nodename, that works. But it does not match the DHCP address, so I get prompted for a new name service because it can't find a DNS entry for the name.
I can write to the zonestorage/etc/hostname.+interface+ and /etc/dhcp.+interface+ (to get the system to register its name with the DNS server after getting its DHCP address) but then I get a system with no root password and no DNS configuration, even though they are set in the sysidcfg file.
I can write a script that gets part of the way using sysidcfg and /etc/... files, then boots the zone and then runs a bunch of voodoo via zlogin commands to fix all the stuff that couldn't be done 'properly', but that's not a 'boot and walk away' environment. I can write a script that uses sysidcfg and hacks around with other files in /etc (like nsswitch.conf, resolv.conf), but that just feels likes a dirty hack to fix something that wasn't done properly in the first place.
So where am I going wrong and how do I do it right (within the constraints defined)? Why can't I configure, boot and walk away?
Thanks

Thanks abrante
Thanks for your response!
I don't think the config is messed up after the installation. I think the installation is fine, it's just not what I want :-)
I'm trying to decouple the zonename from the system name and get DNS registrations working. After installation, a DHCP client can get its hostname from DNS but I'm trying to do it the other way around. I want the DHCP client specify its own hostname, get an address from the DHCP server and then register its hostname with DNS. If the system gets its name from DNS/DHCP then I have to configure those to provide the system name and I don't own the DHCP/DNS infrastructure. These zones are for a development/QA environment, so we create and reconfigure these frequently. Hence the need to specify the system name within the zone and register that name in the DNS.
I have tried fiddling with the PARAM_REQUEST_LIST but it does not seem to be working as I expect. :-$ Removing 12 did not help with setting the hostname from the system. DNS does not have a registered name for this system anyway, so even if it tried to get a name for this system, it would get nothing.
I also do want the DHCP to change the DNS server and domain name, but this does not happen even though my dhcpagent includes 6 and 15 in the PARAM_REQUEST_LIST. I still have to set them in the sysidcfg file because it is always ignored in Solaris (S10u8 with 10_Recommended 30-Jul-2010)
As stated, I know I can hack around with the system after it has booted. But I'm trying to configure the system before it starts and let it take care of itself and not have to touch it. Frankly I'm surprised that the sysidcfg does not allow you to set a hostname name when you are using DHCP, that the default DHCP configuration does not register the system name with the DNS server, and the DNS config from the DHCP response is ignored. Even a sys-unconfiged system requires DNS configuration during initial boot, when I know that the DHCP response contains DNS information.
FYI: Windows systems using DHCP work as expected in this respect by default, i.e. set system name, use DHCP --> system gets address from corporate DHCP, DNS settings are set from DHCP information, DNS registration is made for system name.
I'm working around this at the moment... I call my zone by the system name I want, I hardcode the DNS settings in the sysidcfg file and I create the hostname.+nic+ and dhcp.+nic+ files in the zone storage to get the system to register its name with DNS, them boot.

How to add compiled classes for EJBs in 10.1.3

Hi there,
I have a problem when migrating to 10.1.3.
I have a big library of EJBs which I use in everal projects just by copying precompiled classes and adding them in ejb-jar.xml
In previous JDeveloper I used ant as default build procedure. My build.xml didn't compile anything. just copied precompiled classes to output dir. Thus, the new project didn't care if classes were really build from source or not.
The problem is that new JDeveloper doesn't allow setting a ant task as defualt build procedure and, so, building and then performing a ejb-jar.xml "verify enterprise beans" I get plenty of errors saying it can't find classes. (I have to copy them manually, or run the ant task manually).
It is very tedious to copy classes manually as they are changed often... also, the deployment profile invokes nternal building procedure (an ant task before that copied classes) but now does nothing.
I have tried to add these classes to the src dir, the resource dirs and even classpath, but they never get copied to output directory.
Can I solve this or JDeveloper is only prepared to handle EJBs which source code is owned in the project itself?
Thanks,
Ignacio

That link is to an older version of Jdev. There is no 'Common' section in project properties and no html input path either. There is a 'Project Content' section and within that section there is a 'Web Application' option. However i get "ArrayIndexOutOfBoundsException" whenever i click on the 'Web Application' option. I suspect this is the area where i can configure the .jsp portion of my project. I can't get to it though due to the exception.

JSP Precompile - Doesnt Work

Hi All,
          I am having serious trouble trying to precompile my JSP's and have the wl
          server recognise them (and not re-compile them for me). Im using WLS6.1 with
          SP2 installed.
          I am running the JSPC pre-compiler with -D ....WEB-INF\classes. The files
          get created as expected and then I put them into my WAR file. When I deploy
          the WAR file, WLS always recompiles. I have experimented at length with
          different settings in my weblogic.xml, but as yet have had no success. I
          have also read some previous posts, but these have not helped either.
          Any suggestions or advice are very welcome!
          Thanks,
          Mark


          The suggestion to register JSPs as servlets is not at all practical or acceptable
          to me. Across multiple applications, we have over 200 JSP files and there's no way
          I would even consider this approach. What needs to happen is BEA should fix the problem
          and be more forthcoming about such "bugs" instead of letting the customers serve
          as QA and having to "ask" for patches. Why is 6.1 SP3 not on the web site? Why aren't
          all the patches available online for download? For the amount of money BEA charges,
          especially for clustered licenses, this type of problem should not go unfixed.

WorkManager and ignore-stuck-thread setting

In WL 10.3, using an application scoped work manager with the following .war deployment descriptors:
web.xml:
<resource-ref>
<res-ref-name>wm/WorkManagerABC</res-ref-name>
<res-type>commonj.work.WorkManager</res-type>
<res-auth>Container</res-auth>
<res-sharing-scope>Shareable</res-sharing-scope>
</resource-ref>
weblogic.xml:
<work-manager>
<name>WorkManagerABC</name>
<fair-share-request-class>
<name>abcClass</name>
<fair-share>1000</fair-share>
</fair-share-request-class>
<ignore-stuck-threads>true</ignore-stuck-threads>
<min-threads-constraint>
<name>MinThreadsCountTen</name>
<count>10</count>
</min-threads-constraint>
<max-threads-constraint>
<name>MaxThreadsCountTwenty</name>
<count>20</count>
</max-threads-constraint>
</work-manager>
<wl-dispatch-policy>WorkManagerABC</wl-dispatch-policy>
( This particular app is meant to be a socket listener using javax.nio ). This results in WL seeing "stuck threads" after the default 600 seconds. In our clusters, our clusters are configured that 3 stuck threads cause a server restart by nm.
So I created the same objects at the domain level ( workmanager, min/max/fair-share ), with the workmanager set to ignore stuck threads.
web.xml
<resource-ref>
<res-ref-name>WorkManagerABC</res-ref-name>
<res-type>commonj.work.WorkManager</res-type>
<res-auth>Container</res-auth>
<res-sharing-scope>Shareable</res-sharing-scope>
</resource-ref>
weblogic.xml
<weblogic-version>10.3</weblogic-version>

<wl-dispatch-policy>WorkManagerEni</wl-dispatch-policy>
The app deploys and simple web pages are processed within the WorkManagerABC wm. Although WL still marks 4 threads as hoggers, none of them are stuck. So no restart, and the server Health stays OK.
So a workManager at the server level obeys the "Ignore Stuck Threads" while an application scoped workmanager does not.

I wasn't too disappointed that the application-scoped workmanager didn't obey the stuck threads; I'd rather have the work manager configurable at the server console level without having to involve customized deployment plans to override hard-coded thread restraint levels in the app's deployment descriptors.
I think having it defined within the server console will make it simpler to manage the different performances in production versus qa, etc., than having it defined within the app and then adjusting it in each environment.

"cannot resolve symbol" when compiling a class that calls methods

I am currently taking a Intro to Java class. This problem has my instructor baffled. If I have two classes saved in separate files, for example:
one class might contain the constructor with get and set statements,
the other class contains the main() method and calls the constructor.
The first file compiles clean. When I compile the second file, I get the "cannot resolve symbol error" referring to the first class.
If I copy both files to floppy and take them to school. I can compile and run them with no problem.
If I copy the constructor file to the second file and delete the "public" from the class declaration of the constructor, it will compile and run at home.
At home, I am running Windows ME. At school, Windows 2000 Professional.
The textbook that we are using came with a CD from which I downloaded the SDK and Runtime Environment. I have tried uninstalling and reinstalling. I have also tried downloading directly from the Sun website and still the error persists.
I came across a new twist tonight. I copied class files from the CD to my hard drive. 4 separate files. 3 of which are called by the 4th.
I can run these with no problem.
Any ideas, why I would have compile errors????
Thanks!!

Oooops ... violated....
Well first a constructor should have the same name as the class name so in our case what we have actually created is a static method statementOfPhilosophy() in class SetUpSite and not a constructor.
Now why does second class report unresolved symbol ???
Look at this line
Class XYZ=new XYZ();
sounds familiar, well this is what is missing from your second class, since there is no object how can it call a method ...
why the precompiled classes run is cuz they contain the right code perhaps so my suggestion to you is,
1) Review the meaning and implementation of Constructors
2) Ask your instructor to do the same ( no pun intended ... )
3) Check out this for understanding PATH & CLASSPATH http://www.geocities.com/gaurav007_2000/java/
4) Look at the "import" statement, when we have code in different files and we need to incorporate some code in another it is always a good idea to use import statement, that solves quite a few errors.
5) Finally forgive any goof up on this reply, I have looked at source code after 12 months of hibernation post dot com doom ... so m a bit rusty... shall get better soon though :)
warm regards and good wishes,

* OS has no significance in this error
** uninstalling and reinstalling ? r u nuttttttts ??? don't ever do that again unless your compiler fails to start, as long as it is giving a valid error it is working man ... all we need to do is to interpret the error and try to fix the code not the machine or compiler.

Ignoring back edges in an undirected graph...

let's say i have a graph with 3 vertices. then let's say i have 2 edges connecting vertex 1 (v1) with vertex 2 (v2), and there's one edge connecting v2 with vertex 3 (v3). i want only to print edges going to each vertex, not 'back' edges. how do i do that?
//given - Graph 'g'
Iterator it = g.vertices();
while(it.hasNext()){
Vertex v = (Vertex)it.next();
VertexElement a = v.element();
System.out.println(vertexElement);
Iterator fit = g.incidentEdges(v);
while(fit.hasNext()){
Edge e = (Edge)fit.next();
EdgeElement = e.element();
System.out.println(EdgeElement);
this prints out every edge associated with each vertex.

alright guys, sorry for the previous confusion... i guess i'll go ahead and show all the code associated so you can get a good idea on what i'm trying to do. we're making an airline reservation system built upon a graph in which the vertices are 'airports' and the edges are 'flights'
the information is stored in a text file, which a certain format for airports and a slightly different format for flights. we read the text file, read in the airports and assign them as vertices, then read in the flights, and assign those to edges on the corresponding vertices (there are 'destination' and 'origin' values so we can keep track of which edge to place the elements) the format of the text file is described in detail in the class code, but i'll give an example at the bottom.
here are the classes

the way the flights are set up, i want to display only outgoing flights...
for example, under the Alberquerque airport display, the output will show flight UA785 leaving Alberquerque and arriving at Denver, BUT it will also show flights CO195 & AA305 coming INTO Alberquerque from Denver and Detroit, respectively. I don't want to see that. I only want to see the flights LEAVING a given airport.

Query regarding Application Classes - 2

While going through Classes of Application Package *"EX"*, I have seen that some of the class definitions have a semi-colon after the class-name like:
class ExpenseHeader;
end-class;
While most of the classes are defined without the semi-colon.
class Transaction
end-class;
{color:#000000}+Does this semi-colon make any difference?+{color}

The PeopleCode AppClass API documentation is silent on this. See [http://download.oracle.com/docs/cd/E13292_01/pt849pbr0/eng/psbooks/tpcr/htm/tpcr07.htm#d0e16363|http://download.oracle.com/docs/cd/E13292_01/pt849pbr0/eng/psbooks/tpcr/htm/tpcr07.htm#d0e16363]. When creating your own classes, don't include the semi-colon after the class name (or implements/extends). When reading someone else's classes, ignore it. In this case, I would say the semi-colon makes no difference. I'm not the definitive reference on this, but that is how I would treat it.

Unable to load the '.jsp' file

Hi all,
          We use Weblogic 8.1 sp3 and are devloping a struts based application.
          I have deployed my 'ear' file (containing a '.war' and a '.jar' file). We use struts. Our '.war' file, contains the pre-compiled 'jsp' classes (we have changed our web.xml to indicate that we are using pre-compiled jsps. I can show my web.xml file if you need).
          When I click on my 'submit' button, I see that my action class has been invoked and it's spitting out messages to the stdout. Everything looks fine. But, when it is trying to load the '.jsp', I get the following error.

          I have looked in the '.war' file and it contains the above mentioned precompiled class (_link).
          Could anyone point me in the right direction??

Hi,
          Could you check that whether the jsp file is placed in right place or not ?
          Regards
