Java.lang.Exception: discarding statement JPanel0.add(JTextField0)

This message appears when I try to save a Panel with all subcomponents.
My programm saves JLabel in the resulting Xml-file but neither JTextField nor JComboBox, etc.
I've checked my classes, and all subcomponents of my Spanel are JavaBeans.
(Spanel extends JPanel and has a no-args constructor as well).
So is it a JDK bug?
Hope somebody can help me.
This is my program :
public static void serializeContainer(Container spanel,String fileName) throws IOException {
FileOutputStream fos = new FileOutputStream(fileName);
XMLEncoder encoder = new XMLEncoder(fos);
encoder.setExceptionListener(new ExceptionListener() {
public void exceptionThrown(Exception exception) {
exception.printStackTrace();
encoder.writeObject(spanel);
encoder.close();
And this is the printStackTrace :
java.lang.Exception: discarding statement JPanel0.add(JTextField0);

Java.lang.Exception: Exception in sending Request :: null on Windows7 64bit

Dear All,
I have installed Oracle 10g 32-bit on Windows 7 64-bit Ultimate Edition. After setting ORACLE_HOME and ORACLE_SID environment variables.
Oracle connected to sqlplus fine. But when starting Enterprise Manager in browser following error displayed.
The Enterprise Manager takes the SYS logon (as sysdba) quite happily and then it states:
Error
java.lang.Exception: Exception in sending Request :: null
Status Status Pending
Status Pending Since Unavailable
Last Known State
Please help anyone. This is so urgent.
Regards,
Rizi -DBA

I have resolved this issue myself. Basically problem is due to TimeZone mismatch of Oracle database and Window or OS.
Following are the steps to resolve the issue:-
On DOS prompt issue following commands.
1. emctl stop dbconsole
2. Following file contains valid supported TimeZones and select according to your region:-
e.g. Asia/Karachi
$ORACLE_HOME/sysman/admin/supportedtzs
3. Now open following file:-
$ORACLE_HOME/computername_SID/sysman/config/emd.properties
At the end of this file add:-
agentTZRegion=Asia/Karachi
4. emctl start dbconsole
5. Open browser and logged in Enterprise Manager using sys/password as sysdba.
Click on Pending Status and logged in again, Now you will successfully use Enterprise Manager.
Anyways, Thanks for your effort.

Hi
I saw your issue and found one think that "String index out of range", can you please compare the columns datatype and column size with target table and ODI table.
ODI Table:
After Reverse Engine, CSV changed into table format can you please open the table from designer>model>csv table and goto columns tab, it will list out the all column name datatype and size. compare the column size and type with your target table.
hope this will resolve your issue.

Hi Pig,

java.lang.Exception: ORA-00020: maximum number of processes (150) exceeded
     void MyFolder.objects.MyObject.<init>(oracle.jbo.ApplicationModule, java.lang.String, java.lang.String, javax.servlet.http.HttpServletRequest)

     void com.evermind.server.http.HttpRequestHandler.run(java.lang.Thread)
     void com.evermind.util.ThreadPoolThread.run()
Question:
- What is the cause of this error message? How to avoid?.
From the Oracle error message documentation:
ORA-00020 maximum number of processes (string) exceeded
Cause: All process state objects are in use.
Action: Increase the value of the PROCESSES initialization parameter.
Another alternative approach may be to configure your Connection pool and/or your ApplicationModule pool to optimize the use of
database connections and/or restrict the number of database connections used by the application. For example, if your application
has declared many root ApplicationModules (i.e. more than one ApplicationModule pool is in use) then it may help to enable the
jbo.doconnectionpooling switch so that each ApplicationModule instance in the pools does not maintain a dedicated database
connection while not in use. Another alternative if you are using the BC4J connection pool (not a JDBC datasource) may be to
restrict the number of connections the pool can create to < 150 with the jbo.maxpoolsize switch. However, please note that this
may have an impact on throughput.
- I intended to deploy my application to 9IAS server. Will the same problem occurs too?.
This is a database issue. So, yes.
Hope this helps.

Any clue about why this error would occur?

Java.lang.Exception: No Such Target - wait_bottlenecks

I am using OEM 11g and getting following error on one of the database environment.
java.lang.Exception: No Such Target - wait_bottlenecks
I have tried few options based on following oracle note, still no success.
I have one node RAC. But there are two instances seen in OEM, one is down.
Also, following error is displayed under database target of OEM: Metric Collection Error
6.3.4 Oracle Enterprise Manager Database Control Error
The Oracle Enterprise Manager Database Control home page may show the following error if the dynamic properties evaluation is not complete:
java.lang.Exception: No Such Target - wait_bottlenecks
Workaround:
Run these emctl commands on the master agent. Go to the cluster database home page and click View All Properties link to identify the master agent host. Recompute dynamic properties for the Oracle RAC instance and Oracle RAC database on the master agent host using the following commands:
emctl reload agent dynamicproperties rac_instance_target_name:oracle_database emctl reload agent dynamicproperties rac_database_target_name:rac_database
If the error persists, then increase the timeout for dynamic properties for the target by editing the emd.properties file located at$ORACLE_HOME/host_dbname/config, and providing a larger value for timeout_value. Increase the timeout value on all the nodes of the cluster. For example:
dynamicPropsComputeTimeout_oracle_database=timeout_value dynamicPropsComputeTimeout_rac_database=timeout_value emctl reload agent emctl reload agent dynamicproperties rac_instance_target_name:oracle_database emctl reload agent dynamicproperties rac_database_target_name:rac_database
This issue is tracked with Oracle bug 12907579.

Error message is same in listener log and EM trace file. Also, same message is repeating in listener log, may be OEM is keep on trying to connect to database.

thanks in advance

I assume your signature is correct.
Signing the applet enables privileges (like file IO) whenever all the calls on the stack leading
to the sensitive operation (in your case fis = new FileInputStream("c://premji.rar")) originate
from the signed jar. It is not your case, as you come into the applet from javascript.
The solution is to use AccessController.doPrivileged...(). It was designed with this situation in mind.

Why use customized / particular exceptions instead java.lang.Exception

Hi,
Do any of you guys know where can I find a theorical statement / explanation about why use particular / customized exceptions instead java.lang.Exception? I am aware that it consumes more resources and becomes a heavier object, as well as the clearness when coding and all that stuff; however, my boss wants to see a tech document where all this is clearly stated. Any resource over there?
Regards

It is better to throw specific--or at least module- or
package-specific--excpetions, rather than Exception,
because then the caller knows what to expect. However,
if you declare "throws Exception", the caller can
still catch IOException, SQLException, etc.,
separately. He'll just have to be a really good
guesser as to which ones he should catch.True.
Also, there's no point in declaring "throws
NullPointerException." Any method can throw it without
declaring it. If you generate your own NPE (or other
unchecked exception) inside the method, then you
should document it in the javadoc comments, but you
don't need to put it in the throws clause. It doesn't
do any harm, but it's redundant and cluttersome.It was an example and I wasn't feeling too creative....excuse me. ;-) But yeah, I've never thrown NPE ever.
I'm assuming overhead caused by extending classes.At
the worst, it would be miniscule, or so I wouldthink.
What overhead is created by extending classes?Hmm, I was under the impression that a class the extended another class, inherited all of the other classes data (variables, etc.). Hence, you get something like this:
SuperClass1 + SubClass1 + SubClassOfSubcCass1 = Memory usuage for SubClassOfSubClass1.
Since adding postivie number will always end up increasing data, SubClassOfSubClass1 will use more dtat than SuperClass1.
Am I wrong?

Unreported exception java.lang.Exception; must be caught or declared

I've got a piece of code that's causing an error during compilation.
W:\Java\Covenant\src\covenant\Login.java:174: unreported exception java.lang.Exception; must be caught or declared to be thrownThe line of code it is refering to is:
new Overview().setVisible(true);And it is part of a try/catch statement:
    private void logincheck(java.awt.event.ActionEvent evt) {
        try {
            char[] PasswordInput = Password.getPassword();
            String PasswordRaw = new String(PasswordInput);
            String Passwordmd5 = md5(PasswordRaw);
            String UsernameInput = Username.getText();
            URL theUrl = new URL("http://www.phoenixrising.at/iris/validate.php?login=1&u=" + UsernameInput + "&p=" + Passwordmd5 +"");
            BufferedReader in = new BufferedReader(
                    new InputStreamReader(
                    theUrl.openStream()));
            String inputLine = in.readLine();
            if (inputLine.equals("valid")) {
                new Overview().setVisible(true);
                this.setVisible(false);
                System.out.println( "You have entered the correct password" );
            } else {
                System.out.println(theUrl);
            in.close();
        } catch (MalformedURLException ex) {
            ex.printStackTrace();
        } catch (IOException ex) {
            ex.printStackTrace();
    }      Can anyone see what might be causing this error?

Can anyone see what might be causing this error? That line of code declares that it throws exception java.lang.Exception, so you must either catch it ("must be caught" - like you do the more specific Exceptions) or declare your logincheck method to throw it ("or declared to be thrown").

What could cause "Internal error: java.lang.NullPointerException: can't not add null to SWF frame" when using compc?

using flex sdk 4.6, and air sdk 15.0.0.356
we get the following error when using compc in our ant build:

which seems to be rather vague, and offers no clue as to what caused the problem. so, my question is, what could cause this error?
these are the compiler options we use in the build file:
<java jar="${flex.compc.jar}" dir="." fork="true" failonerror="true">
      <jvmarg value="-Xmx512m" />
      <arg line="@{options} ${_compc.libpath} ${_compc.externspath} ${_compc.includespath}" />
      <arg value="+flexlib=${flex.frameworks.dir}" />
      <arg value="-load-config=@{config}" />
      <arg value="-source-path=@{src.dir}" />
      <arg value="-include-sources=@{src.dir}" />
      <arg value="-output=@{dest}" />
      <arg value="-swf-version=@{swf.version}"/>
      <arg value="-debug=${flash.debug}"/>
      <arg value="-advanced-telemetry"/>
</java>
assume that the properties resolve to correct values, since all projects (except one) call this task and compile successfully. the error must come from this one project that fails, but we don't know why.
any ideas?

You could be running out of memory, try increasing the -Xmx512m value to -Xmx1024m or another value that you prefer
