PXIe-8101 Unable To Compile Code
Hello,
My system is a PXIe-1065 chassis (I've also had the same issue in the PXIe-1082 chassis), PXIe-8101 controller with Windows 7 installed by NI, and the following instruments:
DMM PXI-4071, Power Supply PXI-4110, DAQ PXIe-6356, Timing Card PXIe-6674T, and Motion Control PXI-7332.
I also have a PXIe-8361 which I will use on occasion and will be what I use in the long term.
Now for the actual problem. What happens is I'll put together some code in labview using the instrument driver VI's and everything will work fine. I can make VI's that call subVI's that call the instrument VI's and it works great, but if I double click on an instruments VI and then try to look at the block diagram, for example, opening "DAQmx Create Channel (AI-Voltage-Basic).vi" it seems to break the code. Initially it won't say anything but once I hit the run button the arrow will change to the broken gray arrow and will state that the code failed to compile (this is without actually changing anything with the VI, I open it and look at what it is doing).
Also any code I've written that called that VI will now get the same error, if I click show error it will bring up whatever window I was looking at last, so if I was looking at the front panel, then clicked show error it would just bring up the front panel again without highlighting anything. If I create a new file and build a small vi that uses the instrument drivers it works fine, if I copy the vi's from the broken code and paste it into the new file it will fail with the same error.
It doesn't have this behavior with all the instrument VI's but will happen with some. I mentioned it happens with "DAQmx Create Channel (AI-Voltage-Basic).vi" but then it doesn't happen with "DAQmx Timing(Sample Clock).vi". I haven't gone through and checked exactly which VI's it happens with but it seems to happen with other instruments drivers as well, not just for the DAQ. It also only seems to happen when using the PXIe-8101. If I connect it to a computer this issue doesn't pop up. My company primarily controls the chassis using MXI cards so we don't have any available embedded controllers I could swap in to see if it still happens.
It's not a big issue as looking into the instrument vi's isn't necessary for me to do my job, I just do it to try to better understand what exactly is happening but it is something I'm curious about.

Solved!
Go to Solution.
At the time I first noticed this error I was just starting to use labview, so I simply avoided opening that vi, now I've been working with labview for about 9 months. I haven't been working with it consistently, not all my projects require it, but I would say I've spent at least half my time working with it.
Well I seem to have recorded it slightly off. So when I looked into the DAQmx vi it gave an error and when I clicked show details it gave the following:
When I tried to exit it asked me if I wanted to save the changes, I chose defer decision and eventually chose do not save. I closed labview and reopened the VI, tried to run it and it gave the error:
I selected show error and it gave:
Then where it said it failed to compile was within another vi in the same project. When I first opened it it said SubVI is not executable. When I clicked show error it took me to a VI that had the DAQmx vi in it and it was saying VI failed to compile.
I've attached the SubVI from which I opened the DAQmx. It's a basic vi to read analog data. Is that what you meant for screenshots?

Unable to compile code referencing GV$AQ view
I am unable to compile code which has a select from the view GV$AQ. I have the AQ_ADMINISTRATOR_ROLE granted for myself, but this isn't being granted to the stored procedure. How do I go about granting select privileges on the GV$AQ view? My attempt follows:

You are right, if we are giving priviledges explicitly , it works .
can't we do anything else because in this way at start of the financial year we have to grant so many explicitly priviledges .Yes, don't create database objects that are named based on data (e.g. names with months and years in them).
Data should be inside the table and not used to distinguish the table. -
Unable to compile class for JSP
Please can anyone help me to solve this.
Actually,this is the condition.
In my db,there is a table called UserPassword, which has 4
fields(empNo,UserName,password,level). Now I want to do these things:
When the user submits the data to create a new account via HTML form, it submits the data to the file called CreateAcc.jsp. In this file it perform some logic,here are they.
1)To check the empNo,if it is already exist in the DB,
if empNo =exist then display error.(record already exist)
if empNo =notexist then do task 2).
2)check the UserName,if it is already exist in the db,
if UserName=exist then display error.(because it's a primary key)
if UserName=notexist then do task 3).
3)Create a new user account and save it to the db.
To do these tasks,I never create a new objects for the tasks 1) and 2).
only for task 3)create an object.
Is it the right way?
Here is the file CreateAcc.jsp
<%@ page language="java" %>
<%@ page import="core.UserAccManager" %>
<%@ page import="data.UserPassword" %>
<jsp:useBean id="UserAccManager" class="core.UserAccManager" scope="session"/>
<jsp:setProperty name="UserAccManager" property="*"/>
<jsp:useBean id="UserPassword" class="data.UserPassword" scope="session"/>
<jsp:setProperty name="UserPassword" property="*"/>
<%
String nextPage ="MainForm.jsp";
if(UserPassword.verifyEmpno()){
if(UserPassword.verifyUsername()){
if(UserPassword.createAcc()) nextPage ="MsgAcc.jsp";
}else{
nextPage="UserNameExist.jsp";
else{
nextPage="UserAccError.jsp";
%>
<jsp:forward page="<%=nextPage%>"/>The directory structure:
UserPassword.java- F:/Project/core/data/UserPassword.java
UserAccManager.java - F:/Project/core/UserAccManager.java

Are there any mistakes? If so tell me where is it and how to change them.Please help.I try it that way, but it don't compile.

So,I comment them only in the UserPassword.java file,and compile it again.
Then it compile well.I goto the directory to get the .class files.
But there is only UserPassword.class inside the data folder. There is not
UserAccManager.class in the core folder.
Then I try this way,I put my 2 java files in to a new folder,

Error during distribution for compiled code generation-Reply
Hi,
Looking at your error messages, it looks as though your build is failing during the code generation phase of an autocompilation. To determine why the code generator crashed, either look in the $FORTE_ROOT/log/forte_ex*.log files or don't use autocompilation and use fcompile.
There are many reasons why the code generator could crash. Some of the things I've come across are running out of memory and trying to find invalid classes.
If its the invalid class problem you'll find a message like:
Generating code for partition BLTCustomWindow_cl0_Part1.
ERROR: Exiting due to following exception:

Integrate the changes to the workspace, start the build again and this should have cured the problem.
However, its hard to know what the cause of your problem is without seeing the output in the log files.
Good luck.

Hi,
I'm doing application distribution for my application using a fscript
script and am forcing compilation on 2 of my partitions.
This I have been doing from quite sometime successfully. Recently I
developed a new service and plugged it into my application for
deployment.
I'm successfully able to distribute & deploy the interpreted code. But
I'm getting a long list of system errors when I try doing distribution
for compiled code. And I see only one of the .exe generated instead of
two because of which I'm unable to go ahead with installaion. I would
appreciate if anybody let me know why this's happening ?. The following
is the main chunk of this error list.
Thanks in advance.

Tomcat 4.1 Bean error (Unable to compile class for JSP)
Help,
I am using Tomcat 4.1 with with JDK1.3.1_01. I have a JSP page in which I try to use a Bean, but I get the following error from Tomcat.
The JSP page is very simple. I am using package names in the import statement. Code below.
I've put the class files under

***************** END TOMCAT ERROR MESSAGE *********************Hi
I am running my Tomcat apps (on a Windows dev machine) in an alternate location (ie. not default webapps). The same crap comes to me every time. Unable to install etc. I have tried every trick in the book regarding classpath settings etc.
When I use 'javap' to check the classpath from any location on my machine, its works and javap returns the signature of my class.
When I use it though Tomcat (with the import set to include the filename), it get the error. I have heard rumors that using JDK 1.3 in stead of 1.4 helps, but I just want it to work with 1.4 :)
So if any of you can help me on this, please.
PS. On my linux server it works just fine, as does every other thing on that machine ;)

Release 12.0.4 "ego" pages: unable to compile standard .java
Hi All,
I have downloaded all the necessary files and was able to build a local copy of particular set of pages. I even ran those pages in my local setup.
Then to understnad the flow I decompiled few controller CLASS files using JAD. Now I am unable to compile the java files (i have just added few System.out.println's) .
I get errors for the following piece of standard code:
oaapplicationmodule.invokeMethod("getTrainStationsContent", new Serializable[] {
key
, new Class[] {
oracle/jbo/Key ---> Cause of error
I also tried rephrasing "oracle/jbo/Key" as "(Class)oracle.jbo.Key" but no luck.
The error which is displayed is
Error(732,13): field oracle not found in class oracle.apps.ego.item.eu.webui.EgoCreateItemPageLayoutCO
Error(732,20): field jbo not found in class oracle.apps.ego.item.eu.webui.EgoCreateItemPageLayoutCO
Error(732,24): field Key not found in class oracle.apps.ego.item.eu.webui.EgoCreateItemPageLayoutCO
I have checked the import section and it looks fine to me.
Please let me know if any of you have faced this issue before? Am a bit lost here.
Thanks in advance.,
JayI tried with almost every other decompiler available... but nothing resolves this issue. Please let me know if you have anyother alternative.
Thanks again! -

}A very common question. Tomcat dislikes classes which are not packaged. So, add a package statement in your UserBean.java
package beans; // or something like thatand then place the compiled class file UserBean.class into WEB-INF/classes/beans.
Put the import statement into the JSP accordingly and try again.

}I read in one blog (actually - the only page which was returned by yahoo - so - this should be very rare error!!!) to try to use Sun server's verifier.bat - and - it reported 0 errors and 0 warning. Build was succesfull as well and also - deployment was without errors - but - above mentioned error appeared during the automatic compilation of jsp pages/servlet when newly deployed jsps are first accessed from remote browser.
So - is it possible, please, to receive some advice - what to do further? I feel that my invoice.jsp page can be with errors, - however - the original welcomeJSF.jsp should be working without errors even the erronwous JFS jsp page is added to web application.
Thans for any adice or hint in advance!!!OK - I have made 'clean and build main project' from NB menu and the deployed the resulting *.war and the error messages have disappeared... So - it seems to be bug...

Error:Unable to compile class for JSP
Hi all,
I am new at jsp,just started to learn a week ago :) Anyway I'm having troubles with using a compiled java class in jsp code.I use tomcat 4.1.31 and java 1.4.2.I have compiled the following programm and put the class into tomcats' webapps\ch06\WEB-INF\classes directory
public class ch06_01
public ch06_01()
public String msg()
return "Hello from JSP!";
Then I have the following jsp file in the webapps\ch06 dir as well:
<%@ page import="ch06_01" %>
<HTML>
<HEAD>
<TITLE>Using a JavaBean</TITLE>
</HEAD>
<BODY>
<H1>Using a JavaBean</H1>
<% ch06_01 messager = new ch06_01(); %>
The message is: <%= messager.msg() %>
</BODY>
</HTML>
But when I try to ran the jsp page following error occures:
org.apache.jasper.JasperException: Unable to compile class for JSP
An error occurred at line: -1 in the jsp file: null

Can anybody help me,please!I appreciate your help a lot!
Thank you verry much!
Best regards DaisyIts not a Tomcat issue per se, but a change in the J2SE.
Its been the case since the release of Java 1.4, when they disabled access to the "default" package. Quite a few of the books written before Java1.4 was released are still around, and there are endless examples around the net that no longer work as a result of this change. -
Unable to compile due to the unavailability of com.sun.rave.designtime pkg
Hi ,
I'm developing the design time jar for a custom component.
But I'm unable to compile my BeanInfo base class( which is given below) because of the unavilability of com.sun.rave.designtime package.
mport com.sun.rave.designtime.CategoryDescriptor;
import com.sun.rave.designtime.faces.FacetDescriptor;
import com.sun.rave.designtime.markup.AttributeDescriptor;
public class TypeAheadBeanInfo extends SimpleBeanInfo
In this code, the classes CategoryDescriptor;FacetDescriptor & AttributeDescriptor are in the com.sun.rave.designtime package.
I could not get this jar eventhough I searched for this jar for more than 3 hrs in the internet. So, it would be great if anybody could please help me to get this jar. PLease Help me!!!!
Thanks
RafiqueThis is just a guess...but it might be in the
openide.jar undre Creator\lib.Hmmm...on second thought take a look at the jar files under Creator Modules. Open the jars and see if you can find it there. I don't think it is in the openide.jar after giving it a quick glance. -

Running DS-5 armcc compiled code (PIC) under Windows EC 2013
Hi All,
i just wanted to know if it is generally (officially) supported to run code that is compiled via the armcc (5.03) from DS-5 under Windows Embedded Compact 2013. Or if this is discouraged (reasons?).
The problem i have:
The bootloader contains some code that must be run during Windows EC Startup. So this code is loaded from the Flash, copied to RAM (reserved and commited via VirtualAlloc and marked as executable) and then the functions are called via FunctionPointers.
The code is compiled and linked as position independent and the stack base register is set accordingly before any function is called via pointer and reset when it returns.
This works in about 9 out of 10 tests without problems. But sometimes i get all sort of exceptions (Data Abort, Prefetch Abort, Unknown Instruction, ...). Most (if not all) of the time they occur when the position independent code runs on one of the two
cores.
The code runs on an i.MX6DQ (dual).
If i only enable one core, i can't reproduce the problem (i assume that multicore-handling and multithreading in WinEC 2013 Update 10 is really well tested and works without problems, so this can't be the real reason).
I've thoroughly checked and debugged the code, i'm really sure there is no illegal access or other problem with the code itself.
Could it be a problem to call code compiled via DS-5 armcc? I've compared assembler code that Visual Studio/Platform Builder generates with code that DS-5 generates (but i'm no assembler expert). I can't see any obvious special code that is added by Visual
Studio/Platform Builder (i.e. that functions need) that is not there in the DS-5 code.
Best Regards
SebastianSo I think you could be able to image some code for ROM from another compiler and without knowledge of Windows CE. However, if the code will be called from Windows CE, this becomes more difficult requiring very careful isolation from the
MMU state, processor state, kernel/user mode, etc. Code that works great when called from the bootloader might not work at all from Windows CE itself. The main problem with mixing code from different compilers is the object file format and conventions for
entry and public names. Very unlikely that you'd be able to "link" code from any other compiler with PB-compiled code.
You might think about the x86 image which can easily call BIOS from the bootloader but which can't even begin to call BIOS from CE itself. The problem isn't the compiler (which is different), but the operating environment differences and assumptions.

Troubleshooting compiled code?
I am using Fieldpont modules to control some lab tests. Since we have a few separate tests, we've decided to use compiled code to cut down on Labview costs.
The issue I'm having is when I have an error in the compiled code on a new install. Is there any way to see where in the code the error is occurring? Maybe some sort of test run mode or something? I know the code interacts with the windows registry as well as a few files on the hard drive. I think this is where the problem is. Unfortunately, I did not write the code, so I'm not certain where the problem could be. I have always been able to easily troubleshoot issues with code when running the full Labview software, but with the compiled code, you can't see the block diagram.
Any help would be greatly appreciated.

How to retrieve constants value from compiled code in jar file?
Hi everyone,
I've been looking for a way to solve this for a week now, without any much success... and I've finally decided to ask the Java gurus for a solution! :-)
Here's what I am basically trying to do:
I have several jar files in which there are only compiled code (.class).
In every class, there are 2 constants (declared as static final String) that I would like to retrieve (one is the version and the other the date of the last modification).
My goal is to print a list of all the classes in the jar files with the values of these 2 constants for each class.
The solution that I have right now to do this does not work properly: for now, I read all the elements of the classpath, check if these are jar files, and if so, I look into each one and load all the classes one by one and print the results.
The problem with this is that it uses the method Class.forName(className) and as some classes are unfortunately present in many jar files (2 or 3 copies), once the classes have been loaded, then it won't be "reloaded".
Without the possibility to "reload" these classes, I cannot see inconsistencies in the versions of the classes present in the jar files.
I have read many articles, and I thought that I could then use a custom classloader and create a new instance of this classloader for each jar file.
2 problems with this:
- according to many posts in the different forums I have read, the jar files should not appear in the CLASSPATH (but this would be easier for me if I could use it...)
- some classes will not be loaded if some classes (present in other jar files) are not loaded... and this makes things really really complicated to implement...
So, I thought that I was maybe doing this the wrong way, and that there might be an easy way out of this...
In fact, I do not need to load the classes... all I need to do, is take a sneak peek at the constants and print their values... and that's it!
Somehow, I think that this is possible to retrieve the values of compile time constants (declared as static final String) as I can see that with Eclipse (when opening a jar file).
So, my question is: how can I do that within my java application?
Or maybe there is another easier solution to do what I need?
Thanks in advance for your help!Hi everyone,
