Cannot seem to read properties file from JSP

Hi all,
In an ISA 4.0 application I want to read a properties file from a JSP to decide whether or not to execute some specific JavaScript code. I want the properties file because in it I can easily configure this externally. I put my properties file in /WEB-INF/classes.
I develop on an environment using Tomcat where this works fine. On an acceptance machine using the SAP J2EE engine however this won't work, to my surprise. Can anyone give me a suggestion on why my properties file is not read?
Here's the Java scriptlet code:
UserSessionData userSessionData = UserSessionData.getUserSessionData(session);
// theme will be something like "themes/zester":
String theme = (String) userSessionData.getAttribute(Constants.THEME_KEY);
boolean showScript = false;
int slashIndex = theme.indexOf('/');
String themeKey = null;
// get the "zester"-like part from the theme:
if(theme != null && slashIndex > -1) {
themeKey = theme.substring(slashIndex + 1);
Properties props = new Properties();
InputStream is = application.getResourceAsStream("/WEB-INF/classes/script.properties");
if(is != null) {
props.load(is);
is.close();
Enumeration keysEnum = scriptProps.propertyNames();
while (themeKey != null && keysEnum.hasMoreElements()) {
   if(theme.toUpperCase().endsWith((String) keysEnum.nextElement())) {
    showScript = true;
    break;
   showScript = false;

Hi Kishor,
Thank you for taking the time!
I agree, this issue may have to do with the deployment. There is however a remark in the <a href="http://java.sun.com/products/servlet/2.3/javadoc/javax/servlet/ServletContext.html">ServletContext</a> interface documentation on methods <a href="http://java.sun.com/products/servlet/2.3/javadoc/javax/servlet/ServletContext.html#getResource(java.lang.String)">getResource()</a> and <a href="http://java.sun.com/products/servlet/2.3/javadoc/javax/servlet/ServletContext.html#getResourceAsStream(java.lang.String)">getResourceAsStream()</a> that may also be of interest here:
"The servlet container must implement the URL handlers and URLConnection objects that are necessary to access the resource."
Is this remark of relevance to the subject, or is this thought too far fetched? Mind you, the documentation also states that "This method allows the servlet container to make a resource available to servlets from any source. Resources can be located on a local or remote file system, in a database, or in a .war file". It should, therefore, be possible to read a file from disk???
Cheers,

Log4J - reading properties file from /WEB-INF directory issue..

I'm just learning to implement Log4J; the approach I am taking for my JSF application running under Tomcat 5.5x is to create an initialization servlet to initialize the logger, and then access the logger instance within my backing beans and application module services. I include log4j.jar file in /WEB-INF/lib and log4j.properties in /WEB-INF.
First I wanted to see if this was a good approach, and secondly I'm having trouble accessing the log4j.properties file from the /WEB-INF directory (see below) - any suggestions on how to set up the path so that the properties file can be found (I receive a java.io.filenotfoundexception)?
Where I'm looking for direction is how to define a single instance of the logger and then access that instance from my java classes versus re-creating the logger in each class.
----- web.xml --------
<servlet>
<servlet-name>LogServlet</servlet-name>
<servlet-class>com.sidehire.view.util.LogServlet</servlet-class>
<init-param>
<param-name>setup</param-name>
<param-value>/WEB-INF/log4j.properties</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
------ LogServlet class ------
public void init()
throws ServletException {
String config = getInitParameter("setup");
PropertyConfigurator.configure(config);
Thanks

Try to put the log4j.properties in your WEB-INF/classes/ directory.
You could wrap one log4j instance in a static method in a utility class, but then you would probably lose other information depending on your logger configuration.
If you create an instance in each class, which after all is just one line like this:
static Logger logger = Logger.getLogger(ChangePasswrdAction.class.getName());
then you are able to get time and method information.

Cannot read Property file from JSP in a Web Module Project

I have tried to read the properties file in two ways but am not able to read it because i cannot find the correct path of the properties file.
1st Method :
Properties props = new Properties();
InputStream is =
application.getResourceAsStream(
"test.properties");
if (is != null) {
props.load(is);
is.close();
Enumeration keysEnum = Props.propertyNames();
while (keysEnum.hasMoreElements()) {
out.println(keysEnum.nextElement()) ;
2nd Method :
Here "com.sap.package" is the package name and "test" is the Properties file name
ResourceBundlebundle = ResourceBundle.getBundle("com.sap.package.test");
for (Enumeration e = bundle.getKeys(); e.hasMoreElements();)
String key = (String) e.nextElement();
out.print((String) e.nextElement());
String s = bundle.getString(key);
request.getComponentSession().putValue(key, s);
I cannot read the properties file even when I keep in it the WEB-INF folder.

Properties props = new Properties();
InputStream is = this.class.getClassLoader().getResourceAsStream(/test.properties);
if(is != null){
props.load(is);
Keep the test.properties in the classes folder under the web-inf folder.
Thanks,
Tim

Unable to read Properties file from Java code

Hi,
The directory structure of my application is as follows:-
My App
++++++ src
++++++++com
++++++++++readProp.java
++++++++resource
++++++++++message.properties
I am trying to read the file as follows:-
<code>
public Static final string FilePath="resource.message.properties"
Here the code to read the file. I tried using the following two techniques but to no use... :(
File accountPropertiesFile = new File(FacesContext.getCurrentInstance()
.getExternalContext().getRequestContextPath()
+ FilePath);
properties.load(externalContext.getResourceAsStream(FilePath));
</code>
But none yeild any sucess while reading through the Bean class. please help...

Your source code isn't there at run time, at least it shouldn't be, so the directory structure you've shown is irrelevant.
If the file is in the corresponding position under WEB-INF/classes at runtime, the second technique should work, but you need to fix FilePath to agree with what it says under Class.getResource() and friends.

Read xml file from jsp/servlet

Hi all,
I am a new comer to jsp and really appreciate if someone can help me on this:
I will like to use a xml file to control access to my web app instead of using a database. Let say user.xml that will contains user name and password. Questions:
1. where should I put this file? Under WEB-INF?
2. In my jsp or servlet, how do i read the xml file, i mean how to i refer to the file (depend on question 1 as where the file should be placed)?
Thank you very much.
Sim

Hi jlsim,
you can place the xml file where you want, but remember that placing it under /WEB-INF is the most security way.
I had a similar problem and I placed the xml file under /WEB-INF directory.
To refer to it I did something like this:
String realPath=getServletContext().getRealPath("WEB-INF/xml/workspaces.xml");//obtain the real path
File f=new File(realPath);//obtain an instance of your file usable
//to create an InputStream

Cannot read properties files in debug mode .....

I am using JDeveloper 10g (10.1.3.0.4) and cannot seem to read properties files in debug mode, while it runs fine in Run (non debug) mode!!
For code like this:
Properties props = new Properties();
String dbPropsFile = "/pol_main.properties";
InputStream is;
is = this.getClass().getResourceAsStream(dbPropsFile); <---- ERRORS HERE!
props.load(is);
I get error messages like:
"Unable to find source file for package oracle.classloader, filename PolicyClassLoader.java".
Cannot go any further.
I am using the "hotspot" virtual machine under Project debug options. Using Sun's
JDK 1.5 update 6 with Ojvm installed.
Thanks.

I think I figured out something. In jDeveloper 10.1.3, open your project properties and click on the Run/Debug treeview branch. Now Edit the Run Configuration you are using (mine is Default) and check the Run Directory. If I change this to be the root of my source, which is one level down from my .jpr file, it now uses my standard path and finds my files. I suppose you could also change this to use the classes directory as the root as long as your props files were there too. My problems seem to be the result of my project root being one folder higher than my source root due to the way our project was imported from CVS. --Ed

How to get File Reference of a properties file from EJB

Hi,
I am using Sun App server 7 with Oracle 9i. I am keeping all my SQL statements in a properties file from which I am loading it while making a database operation from Stateless beans. My problem is I am not able to get the reference of the properties file. Here is the code through which I am getting the SQL statements loaded to a cache.
String sqlFileName = "SQL.properties";
sqlCache.load(new FileInputStream(sqlFileName));
From the cache I am sending the SQL statement depending on the key value. But the problem is I have to keep the SQL.properties file on the App Server config directory of the instance where the server.xml file resides. Otherwise it is not able to find the properties file. But I don't want to put the properties file on the config directory of the server instance. Please help how to get the properties file from the packakge. My file is residing inside a package com.company.sql . Botht the properties file and the class accessing the file are residing in the same package. Please help how to get the reference of the file with out putting the file in the config directory.
Thanks

Just wanted to warn you of the hazards if you read a file from EJB
So please make sure that these hazards will not affect your application. However the solution suggested to use getResourceStream() concurs with ejbSpec
This snippet is from suns blueprint on ejb
Why can't EJBs read and write files and directories in the filesystem? And why can't they access file descriptors?
Enterprise beans aren't allowed to access files primarily because files are not transactional resources. Allowing EJBs to access files or directories in the filesystem, or to use file descriptors, would compromise component distributability, and would be a security hazard.
Another reason is deployability. The EJB container can choose to place an enterprise bean in any JVM, on any machine in a cluster. Yet the contents of a filesystem are not part of a deployment, and are therefore outside of the EJB container's control. File systems, directories, files, and especially file descriptors tend to be machine-local resources. If an enterprise bean running in a JVM on a particular machine is using or holding an open file descriptor to a file in the filesystem, that enterprise bean cannot easily be moved from one JVM or machine to another, without losing its reference to the file.
Furthermore, giving EJBs access to the filesystem is a security hazard, since the enterprise bean could potentially read and broadcast the contents of sensitive files, or even upload and overwrite the JVM runtime binary for malicious purposes.
Files are not an appropriate mechanism for storing business data for use by components, because they tend to be unstructured, are not under the control of the server environment, and typically don't provide distributed transactional access or fine-grained locking. Business data is better managed using a persistence interface such as JDBC, whose implementations usually provide these benefits. Read-only data can, however, be stored in files in a deployment JAR, and accessed with the getResource() or getResourceAsStream() methods of java.lang.Class.
Hope this info helps!

Changing a .properties file from within a programme

Hi, I was just wondering is there anyway that i can change a .properties file from within a programme?
I have certain values in the .properties file and I want to add a username and password to the file once it has been entered in a login part of the programme.
I have had a look at the docs and can not seem to find any suitable methods.
Cheers Gareth.

store is a good method.
In practical use, sometimes you have a .properties file full of comments (properties files are to be modified by humans, and humans need comments), but they are not retrieved by "load" so they will not be stored back by "store". It's a pity that it happens (the equivalent Windows API, WritePrivateProfileString, has a better behaviour).
Maybe someone has written a method that can modify a properties file, without changing the order of the pairs name=value and without throwing out comments.

Cannot open illustartor cc 2014 files from bridge

cannot open illustartor cc 2014 files from bridge... after I installed Illustrator CC 2014 and updated Bridge CC I cannot open the Illustrator files from Bridge as it seems the path for opening such files still points to the old Illustrator CC folder which I have uninstalled from my computer

still points to the old Illustrator CC folder which I have uninstalled from my computer
Probably meaning you did not use the correct procedure for uninstall or have some remnants left of a trial. In Bridge Preferences File Type Associations you can change your default application for opening files of the wanted file types.

When will we be able to read NEF files from a NIKON 5200?

Just got a Nikon D5200. Photoshop and Bridge cannot read NEF files from this camera. It worked fine with my D3100 camera. When will we be able to read NEF files from a NIKON 5200?

Welcome to the forum!
As often, we cannot give a simple answer without more informations: what version of Photoshop and Bridge are you talking about?
The rule of thumb is to update Camera Raw to the latests version compatible with Photoshop, and if it does not work, to download the last version of the DNG converter and use it on the files to convert them to DNG that can be opened in the older versions of Camera Raw and other raw converters.
Normally, to update go to Help>Updates...
According to http://helpx.adobe.com/creative-suite/kb/camera-raw-plug-supported-cameras.htmlhe first version of Camera Raw that can open the NEF from the 5200 is Camera Raw 7.3, that works with Photoshop CS6. If you version of Photoshop is older, you'll need to use the DNG converter 7.4:
(but, since you don't state what operating system you are using, here are the links for both versions:

Unable to load properties file from filesystem

Hi,
I have a client swing-applicatiion packaged in a jar-file. The application uses some resource files, including a xxxx.properties file to set defaults for the application. All resource files are included in the jar file and everything works as expected. I load the xxxx.properties file as follows:
is_ = getClass().getResourceAsStream("/resources/xxxx.properties");
Because it is not possibl to change any property values inside the jar-file without recreating this jar-file, i want to exclude the xxxx.properties file from the jar-file and put it in the folder containing the jar-file.
So i have:
drive:/folder/app.jar
drive:/folder/xxxx.properties
Now i read the xxxx.properties file from disk in stead of the 'resouce'-folder within my application (jar):
is_ = getClass().getResourceAsStream("drive:/folder/xxxx.propoerties");
but it doesn't work, the file isn't found.
What am i missing here?
Any suggestions?

The best way to approach this is to include the properties file in the Jar as you originally did. If the user changes any property, save the entire set of properties to a sub-directory of user.home (perhaps based on the package name of the main class). Check for the copy in user.home before using the 'default' properties built into the Jar.
Other places/ways to store the changed information.
- java.util.prefs.Preferences
- Assuming the app. has a GUI and can be deployed over a network, the JNLP API PersistenceService. Here is a demo. of the PersistenceService (http://pscode.org/jws/api.html#ps).
Edit 1:
I did not at first notice that this post was in Java Applet Development.
<li> Applets can also (theoretically) use cookies to store information. This is prone to failure when users disable cookies.
<li> To store information on the local file system (e.g. in user.home) or to use Preferences (AFAIU) would require trusted code.
<li> If the user has the Next Generation Java Plug-In (Java 1.6.0_10+) it is possible to leverage the JNLP API services in an embedded & sand-boxed applet.

Error while reading excel file from application server into internal table.

Hi experts,
My requirement is to read an excel file from application server into internal table.
Hence I have created an excel file fm_test_excel.xls in desktop and uploaded to app server using CG3Z tcode (as BIN file type).
Now in my program I have used :
OPEN DATASET v_filename FOR INPUT IN text mode encoding default.
DO.
READ DATASET v_filename INTO wa_tab.
The statement OPEN DATASET works fine but I get a dump (conversion code page error) at READ DATASET statement.
Error details:
A character set conversion is not possible.
At the conversion of a text from codepage '4110' to codepage '4103':
- a character was found that cannot be displayed in one of the two
codepages;
- or it was detected that this conversion is not supported
The running ABAP program 'Y_READ_FILE' had to be terminated as the conversion
would have produced incorrect data.
The number of characters that could not be displayed (and therefore not
be converted), is 445. If this number is 0, the second error case, as
mentioned above, has occurred.
An exception occurred that is explained in detail below.
The exception, which is assigned to class 'CX_SY_CONVERSION_CODEPAGE', was not
caught and
therefore caused a runtime error.
The reason for the exception is:
Characters are always displayed in only a certain codepage. Many
codepages only define a limited set of characters. If a text from a
codepage should be converted into another codepage, and if this text
contains characters that are not defined in one of the two codepages, a
conversion error occurs.
Moreover, a conversion error can occur if one of the needed codepages
'4110' or '4103' is not known to the system.
If the conversion error occurred at read or write of screen, the file
name was '/usr/sap/read_files/fm_test_excel.xls'. (further information about
the file: "X 549 16896rw-rw----201105170908082011051707480320110517074803")
Also let me know whether this is the proper way of reading excel file from app server, if not please suggest an alternative .
Regards,
Karthik

Hi,
Try to use OPEN DATASET v_filename FOR INPUT IN BINARY mode encoding default. instead of OPEN DATASET v_filename FOR INPUT IN text mode encoding default.
As I think you are uploading the file in BIN format to Application server and trying to open text file.

Umang Mehta

What are the commands available to read a file from application server and

What are the commands available to read a file from application server and store the file into an internal table?

Hi,
To read a file from an Application Server to an Object there is a command in ABAP called <b>READ DATASET</b>. After that file is transported to that object you have to do a loop and put that data in an Internal Table.
This statement exports data from the file specified in dset into the data object dobj. For dobj, variables with elementary data types and flat structures can be specified. In Unicode programs, dobj must be character-type if the file was opened as a text file.
For dset, a character-type data object is expected - that is, an object that contains the platform-specific name of the file. The content is read from the file starting from the current file pointer. After the data transfer, the file pointer is positioned after the section that was read. Using the MAXIMUM LENGTH addition, the number of characters or bytes to be read from the file can be limited. Using ACTUAL LENGTH, the number of characters or bytes actually used can be determined.
In a Unicode program, the file must be opened with an arbitrary access type; otherwise, an exception that cannot be handled will be triggered.
If the file has not yet been opened in anon-Unicode program, it will be implicitly opened as a binary file for read access using the statement
OPEN DATASET dset FOR INPUT IN BINARY MODE.
. If a non-existing file is accessed, an exception that can be handled can be triggered.
Influence of Access Type
Files can be read independently of the access type. Whether data can be read or not depends solely on the position of the file pointer. If the latter is at the end of the file or after the file, no data can be read and sy-subrc will be set to 4.
Influence of the Storage Type
The import function will take place irrespective of the storage type in which the file was opened with the statement OPEN DATASET.
If the file was opened as a text file or as a legacy text file, the data is normally read from the current position of the file pointer to the next end-of-line marking, and the file pointer is positioned after the end-of-line marking. If the data object dobj is too short for the number of read characters, the superfluous characters and bytes are cut off. If it is longer, it will be filled with blanks to the right.
If the file was opened as a binary file or as a legacy-binary file, as much data is read that fits into the data object dobj. If the data object dobj is longer than the number of exported characters, it is filled with hexadecimal 0 on the right.
If the specified storage type makes conversion necessary, this is executed before the assignment to the data object dobj. Afterwards, the read data is placed, byte by byte, into the data object.
System Fields
sy-subrc Meaning
0 Data was read without reaching end of file.
4 Data was read and the end of the file was reached or there was an attempt to read after the end of the file.
Thanks,
Samantak.

Is this what you downloaded: iTunes 10.7?
When the update fails what if any error report do you get, specifically? Please do this before trying again:
Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
