WebLogic looking for class file using the wrong case

During my ant build, I precompile my JSPs using weblogic.jspc. All of the jars and wars are packaged into an ear and deployed to WebLogic 8.1 on Linux. When I access one of our normal screens, everything is good. Things go wrong when I try to access one of our help screens. We have a base help file that includes another file based on the screen code passed to it. The screen code is used in combination with a HashMap to look up the correct JSP to include. This part goes fine. But when the JSP is included, I get the following error. The best I can figure is that the class file is in mixed case (i.e., SampleHelp00.jsp and SampleHelp00.class), but Weblogic is looking for samplehelp00.class.
I'm not even where I should begin looking to solve this. Anyone have any ideas?

Ignore the part about precompiled JSPs being ignored on my development server. Turns out I had a stale cache. I cleared that out and now it recognizes the files.
The problem with that, is now I'm getting an Error 500 when I try to access the page.

I passed the -keepGenerated flag to the precompile task in my Ant build so I could look at the line it's choking on, but it's not very helpful. I'm stuck. I can set up the build so it doesn't precompile the JSPs, but then the QA team wouldn't like me very much.

(Help) system classpath -Vs- the place where weblogic looks for classes

The following is my app's hierarchy.
myapp
|
|__myjsp.jsp
|
|__WEB-INF
|
|__classes
|_ MyClass.class
I am not able to use MyClass within myjsp.jsp
i.e. a scriplet like that shown below gives an error stating that MyClass isnt found
<% MyClass obj; %>
I've tried setting the system classpath, but to no avail.
Is there a difference between the system classpath and the place where weblogic looks for classes?
(I am running my app by creating a myapp.war file and placing it in autodeploy folder)

Try moving your class to a named package and use the appropriate import statement in your JSP. Loading it from WEB-INF/classes/packagename should be fine so you might want to remove the other classpath mods you made to eliminate that uncertainty.
Here's a snippet from http://publib.boulder.ibm.com/infocenter/dmndhelp/v6rxmx/index.jsp?topic=/com.ibm.websphere.nd.doc/info/ae/ae/rweb_jsp_migration.html:
"As of JSP 2.0, referring to any classes from the unnamed or default package is not allowed. This can result in a translation error on some containers, specifically those that run in a JDK 1.4 or greater environment which will also break compatibility with some older JSP applications. However, as of JDK 1.4, importing classes from the unnamed package is not valid. See Java 2 Platform, Standard Edition Version 1.4.2 Compatibility with Previous Releases for details. Therefore, for forwards compatibility, applications must not rely on the unnamed package. This restriction also applies for all other cases where classes are referenced, such as when specifying the class name for a tag in a Tag Library Descriptor (TLD) file."

Browser looks for class files even tho everything in jars

hi, in my webserver logs I get a lot of 404's for class files. The applet loads fine was just hoping to get the browser not to look for stuff besides the jars I give it. any ideas?

Thanks

any ideas?Not without a better explanation, example, code etc.

Does somebody know an alternative for the deploytool of Sun ?
Thanks a lot !

Lib32-gtk2 looks for theme engines in the wrong place

When starting a 32 bit gtk-app in a 64 bit environment with DE KDE4 I get the following error:
Gtk-WARNING **: /usr/lib/gtk-2.0/2.10.0/engines/libqtcurve.so: wrong ELF class: ELFCLASS64
I have qtcurve installed as well as lib32-qtcurve from AUR (amongst all other 32 bit libs I need). But lib32-gtk2 seems to look in the wrong directory for loading 32 bit themes. lib32-qtcurve is in /opt/lib32/usr/lib/gtk-2.0/2.10.0/engines/libqtcurve.so instead of the path mentioned in the error warning.
Seems like lib32-gtk2 has a wrong path compiled in. Or is there any lib32-specific conf-file I have to edit?
Harvey

Well, since nobody seems to have a clue I filed a bug report for lib32-gtk2and see what happens.

Getting generated class files using the compiler api??

I am writing a compiler/IDE for java, and i use the new JavaCompiler API
(javax.tools.JavaCompiler)
i want to ask, is it possible to get the generated class file(compiled file) names??
can anyone help me with this, read at the documentation and i have no idea which one is used to do such thing..
Or is it impossible??
Thanks, please guide me on this..

don't.

yes, probably (after all, other tools can do it). Don't ask me how though, I've never had a need to.
can anyone help me with this, read at the documentation and i have no idea which one is used to do such thing..
no. Someone else reading the documentation for you won't help you any. Read it yourself, you might learn something.

Looking for APXXTR files on the database

Hi to All,
I have raised an SR with oracle to resolve a expense report issue that takes place in import process. SR asked to locate the following files. Currently looking for the files. Can you anyone shed some light where these files may be on the DB. We are currently using EBS 11.5.10.2 and running Oracle DBMS 10g on windows 2000 server.
src/apxxtr/apidbl.lpc src/apxxtr/apicdl.lpc include/apxxtr.h 115.20
I have asked oracle to specify path of files...but they didnt give much of a good answer.
Any help would be greatly appreciated.

You are likely to get better help in the EBS forum :-)

How to look for my ipod using the serial number

Looking for my stolen ipod using my serial number. Where do I go to do this?

You do not. The SN will only help identify the iPod as yours if it is recovered.
- If you previously turned on FIndMyiPod on the iPod in Settings>iCloud and wifi is on and connected go to iCloud: Find My iPhone, sign in and go to FIndMyiPhone. If the iPod has been restored it will never show up.
- You can also wipe/erase the iPod and have to iPod play a sound via iCloud.
- Change the passwords for all accounts used on the iPod and report to police
- There is no way to prevent someone from restoring the iPod (it erases it) using it.
- Apple will do nothing

Pacman looking for pacman.conf in the wrong place?

When using yaourt, I had been getting an error message to do with pacman.conf not being found. I fixed this by creating my own and saving it in
/usr/local/etc/pacman.conf
(it's the only file in /usr/local/etc)
I then got the error message:
failed to initialize alpm library (could not find or read directory)
After some googling and learning about the find command, I found the following files:
/usr/lib/libalpm.so
/usr/lib/libalpm.so.8
/usr/lib/pkgconfig/libalpm.pc
/usr/lib/libalpm.so.8.0.2
So I'm guessing that I do have the alpm library, but pacman (or Yaourt?) isn't finding it.
Further use of 'find' found the following versions of pacman:
/usr/local/etc/pacman.conf
/etc/pacman.conf
Which then lead me to believe that I have the necessary files but they are in the wrong place or there is a config file (or something) that I need to alter.
Any ideas what I've done wrong and how to correct it?
Thanks, James

I've just tried
pacman -S man-pages
as a test, and it worked ok.
So, Bug Wrangler is probably right. Any ideas how I fix it, or is the solution to start again? If I need to start again, is there an easy way to remove yaourt?

Looking for opinions - anyone using the iPhone in NYC?

I am NOT an iPhone owner yet. But, have been considering buying one. I live/work in NYC and am using a Treo 650 with T-Mobile. The service is so poor that I no longer have a signal in my office or my apt. I am seriously considering the iPhone and wanted to know how other NYers are managing with the iPhone and AT&T service. Would love to hear your opinions.
Thanks!

I live in Manhattan on the east side, near Gramercy.
I was previously on T-Mobile. I had almost no signal in my apt. with T-Mo. With AT&T, I have full bars. However, in the ad agency I freelance in on occasion, my signal with AT&T is worse.
But that may mean nothing to you. What it comes down to is where you live/work and your proximity to an AT&T tower in those locations. Unless you can get testimonials from another user(s) in your exact living/working location(s), no amount of anecdotal evidence from other people anywhere else around the city will guarantee you a good or bad signal. This is especially true of the EDGE network, which varies from block to block. You can turn a corner and drop/gain 100kbps.
My recommendation would be to find a neighbor or co-worker on AT&T, take the sim card out of their phone, put it in yours and note the signal quality. Be sure to do this as close as possible to where you live/work. Using your phone instead of theirs will provide you with a test control. Of course, if you could get your hands on a friend's iPhone, even better.

Looking in the wrong directory for class file

My javabean looks like this:
<jsp:useBean id="mailer" class="MailerBean">
<jsp:setProperty name="mailer" property="*"/>
<% mailer.sendMail(); %>
</jsp:useBean>
The actual MailerBean.class file is in ROOT/public_html/servlets directory. The file that uses the above javabean is in ROOT/public_html/clearresults directory. I have tried a bunch of different lines of code to point to the servlets directory with no success. The javabean continues to point to the ROOT/public_html/clearresults/MailerBean.class file when it should point to ROOT/public_html/servelts/MailerBean.class. How can I point the MailerBean class to the servlets directory without moving the file that uses the javabean?

Generally you don't have to write code to say where a class is, and I don't know what "pointing" a class is. Things that run servlets and JSPs have rules about where they will look for classes. All you have to do is put your MailerBean class where the rules say to put it. Often that's a directory called something like .../WEB-INF/classes, but check out the rules for your product.

How do I make a batch file if the .class file uses a foreign package?

I am trying to make an MS-DOS batch file using the bytecode file from the Java source file, called AddFields.java. This program uses the package BreezySwing; which is not standard with the JDK. I had to download it seperately. I will come back to this batch file later.
But first, in order to prove the concept, I created a Java file called Soap.java in JCreator. It is a very simple GUI program that uses the javax.swing package; which does come with the JDK. The JDK is currently stored in the following directory: C:\Program Files\Java\jdk1.6.0_07. I have the PATH environment variable set to the 'bin' folder of the JDK. I believe that it is important that this variable stay this way because C:\Program Files\Java\jdk1.6.0_07\bin is where the file 'java.exe' and 'javac.exe' are stored. Here is my batch file so far for Soap:
@echo off
cd \acorn
set path=C:\Program Files\Java\jdk1.6.0_07\bin
set classpath=.
java Soap
pause
Before I ran this file, I compiled Soap.java in my IDE and then ran it successfully. Then I moved the .class file to the directory C:\acorn. I put NOTHING ELSE in this folder. then I told the computer where to find the file 'java.exe' which I know is needed for execution of the .class file. I put the above text in Notepad and then saved it as Soap.bat onto my desktop. When I double click on it, the command prompt comes up in a little green box for a few seconds, and then the GUI opens and says "It Works!". Now that I know the concept of batch files, I tried creating another one that used the BreezySwing package.
After I installed my JDK, I installed BreezySwing and TerminalIO which are two foreign packages that make building code much easier. I downloaded the .zip file from Lambert and Osborne called BreezySwingAndTerminalIO.zip. I extracted the files to the 'bin' folder of my JDK. Once I did this, and set the PATH environment variable to the 'bin' folder of my JDK, all BreezySwing and TerminalIO programs that I made worked. Now I wanted to make a batch file from the program AddFields.java. It is a GUI program that imports two packages, the traditional GUI javax.swing package and the foreign package BreezySwing. The user enters two numbers in two DoubleField objects and then selects one of four buttons; one for each arithmetic operation (add, subtract, multiply, or divide). Then the program displays the solution in a third DoubleField object. This program both compiles and runs successfully in JCreator. So, next I moved the .class file from the MyProjects folder that JCreator uses to C:\acorn. I put nothing else in this folder. The file Soap.class was still in there, but I did not think it would matter. Then I created the batch file:
@echo off
cd \acorn
set path=C:\Program Files\Java\jdk1.6.0_07\bin
set classpath=.
java AddFields
pause
As you can see, it is exactly the same as the one for Soap. I made this file in Notepad and called it AddFields.bat. Upon double clicking on the file, I got this error message from command prompt:

I know that most of this makes no sense; but that it only means that it cannot find the class BreezySwing or GBFrame (which AddFields extends). Notice, however that it does not give an error for javax.swing. If I change the "set path..." command to anything other than the 'bin' folder of my JDK, I get this error:
'java' is not recognized as an internal or external command,
operable program or batch file.
Press any key to continue . . .
I know this means that the computer cannot find the file 'java.exe' which I believe holds all of the java.x.y.z style packages (native packages); but not BreezySwing or any other foreign packages. Remember, I do not get this error for any of the native Java packages. I decided to compare the java.x.y.z packages with BreezySwing:
I see that all of the native packages are not actually visible in the JDK's bin folder. I think that they are all stored in one of the .exe files in there because there are no .class files in the JDK's bin folder.
However, BreezySwing is different, there is no such file called "BreezySwing.exe"; there are just about 20 .class files all with names like "GBFrame.class", and "GBActionListener.class". As a last effort, I moved all of these .class files directly into the bin folder (they were originally in a seperate folder called BreezySwingAndTerminalIO). This did nothing; even with all of the files in the same folder as java.exe.
So my question is: What do I need to do to get the BreezySwing package recognized on my computer? Is there possibly a download for a file called "BreezySwing.exe" somewhere that would be similar to "java.exe" and contain all of the BreezySwing packages?

There is a lot of detail in your posts. I won't properly quote everything you put (too laborious). Instead I'll just put your words inside quotes (").
"..there are some things about the interface that I do not like."
Like +what?+ This is not a help desk, and I would appreciate you participating in this discussion by providing details of what it is about the 'interface' of webstart that you 'do not like'. They are probably misunderstandings on your part.
"Some of the .jar files I made were so dangerously corrupt, that I had to restart my computer before I could delete them."
Corrupt?! I have never once had the Java tools produce a corrupt Jar. OTOH, the 'cannot delete' problem might relate to the JRE gaining a file lock on the archive at run-time. If the file lock persisted after ending the app., it suggests that the JRE was not properly shut down. This is a bug in the code and should be fixed. Deploying as .class files will only 'hide' the problem (from casual inspection - though the Task Manager should show the orphaned 'java' process).
"I then turned to batch files for their simple structure and portability (I managed to successfully transport a java.util containing batch file from my computer to another). This was what I did:
- I created a folder called Task
- Then I copied three things into this folder: 1. The file "java.exe" from my JDK. 2. The program's .class file (Count.class). and 3. The original batch file.
- Then I moved the folder from a removable disk to the second computer's C drive (C:\Task).
- Last, I changed the code in the batch file...:"
That is the +funniest+ thing I've heard on the forums in the last 72 hours. You say that is easy?! Some points.
- editing batch files is not scalable to 100+ machines, let alone 10000+.
- The fact that Java worked on the target machine was because it was +already installed.+ Dragging the 'java.exe' onto a Windows PC which has no Java will not magically make it 'Java enabled'.
And speaking of Java on the client machine. Webstart has in-built mechanisms to ensure that the end user has the minimum required Java version to run the app. - we can also use the [deployJava.js|http://java.sun.com/javase/6/docs/technotes/guides/jweb/deployment_advice.html#deplToolkit] on the original web page, to check for minimum Java before it puts the link to download/install the app. - if the user does not have the required Java, the script should guide them through installing it.
Those nice features in deployJava.js are available to applets and apps. launched using webstart, but they are not available for (plain) Jar's or loose class files. So if 'ensuring the user has Java' is one of the requirements for your launch, you are barking up the wrong tree by deploying loose class files.
Note also that if you abandon webstart, but have your app. set up to work from a Jar, the installation process would be similar to above (though it would not need a .bat file, or editing it). This basic strategy is one way that I provide [Appleteer (as a downloadable ZIP archive)|http://pscode.org/appleteer/#download]. Though I side-step your part 1 by putting the stuff into a Jar with the path Appleteer/ - when the user expands the ZIP, the parts of the app. are already in the Appleteer directory.
Appleteer is also provided as a webstart launched application (and as an applet). Either of those are 'easier' to use than the downloadable ZIP, but I thought I would provide it in case the end user wants to save it to disk and transport the app. to a machine with no internet connection, but with Java (why they would be testing applets on a PC with no internet connection, I am not sure - but the option is there).
"I know that .jar and .exe files are out because I always get errors and I do not like their interfaces. "
What on earth are you talking about? Once the app. is on-screen, the end user would not be able to distinguish between
1) A Jar launched using a manifest.
2) A Jar launched using webstart.
3) Loose class files.
Your fixation on .bat files sounds much like the adage that 'If the only tool you have is a hammer, every job starts to look like a nail'.
Get over them, will you? +Using .bat files is not a practical way to provide a Java app. to the end user+ (and launching an app. from a .bat looks quite crappy and 'second hand' to +this+ user).
Edit 1:
The instructions for running Appleteer as a Jar are further up the page, in the [Running Appleteer: Application|http://pscode.org/appleteer/#application] section.

Launching Microsoft Access from Internet Explorer to view a downloaded MDB file opens the wrong file (not a problem if I use Firefox)

When clicking on a link (in Internet Explorer 9) to download an Access MDB file and then choosing to open the file directly in Microsoft Access (2007) instead of saving it, the file is copied to Temporary Internet Files but Microsoft Access tries to open
a different file and displays an (Unrecognized database format) error.
When I click on the option to open the file, the MDB file is copied to Temporary Internet Files\Content.IE5 but instead of that file, Access tries to open a different (incorrect) file located in Temporary Internet Files\Content.MSO (e.g. in the above error
message, NativeView.do is an XML file containing an error message).
I don't see this problem with Word, Excel or PowerPoint files. When opening a Word file (without saving) the Word file is copied to Content.IE5 but an identical .tmp file is created in Content.MSO which when opened in Microsoft Word displayed the required file
correctly. The same happens for Excel files. PowerPoint appears to be handled a little differently (no .tmp file created in Content.MSO but the required file is still copied to Content.IE5) but the PPT file is still opened correctly in Microsoft PowerPoint.
I think the Content-Type "application/msaccess" is fine because Internet Explorer does launch Microsoft Access. It just tries to open the wrong file (or so I think). However, it looks like the file type is not being determined. Here is what I noticed
when trying to open different Microsoft Office files using Internet Explorer:
The last one is the MDB file. As you can see, only for this type of file, the "Type" (Microsoft Office Access 2007?) is not displayed in this Open/Save dialog box.
On Firefox, I don't see this problem. When I tried clicking on the link to the MDB file in Firefox, Microsoft Access was launched and the file was opened correctly. Is there something I can do so the MDB file is opened properly using IE? I can add/change headers
in the HTTP response that writes this file to the output stream (on disk) if that helps.
Thanks for your time!

Sounds like a problem symptom to be discussed in either an IE forum or an Access forum, not here. How did you come to post here? ForumsRedesign. That might be an on-topic issue for this forum. <eg>
Can you find your way to either of those other forums easily from here? Another on-topic question for here I think. ; )

Oops, my bad. Thanks for letting me know! :)
I've re-posted it here: http://social.technet.microsoft.com/Forums/ie/en-US/1a818501-296c-42fb-8abb-ba914629c962/launching-microsoft-access-from-internet-explorer-to-view-a-downloaded-mdb-file-opens-the-wrong-file?forum=ieitprocurrentver
Hopefully that's the right place for this.
