Read resourceBundle properties file from KM

Hi,
I have a properties file called com.mycomp.apps.phonebook.properties in the KM Content of the portal in KM Content => root => mycomp => apps => phonebook => customizing
Now I'm developing a new LinkCommand service for the UserDetails.
http://help.sap.com/saphelp_nw04/helpdata/en/65/29b24053c13f5fe10000000a155106/frameset.htm
The already existing LinkCommand "Send E-mail..." is read from the original resourceBundle com.sap.ip.collaboration.gwui.api.wdf.mail.SendTo
For my new LinkCommand I would like to use the existing properties file. How do I have to define this file in the uicommand xml or properties xml sheet?
Can anybody help me?
With the local project resourceBundle it's working, but I would like to use the file in the KM. Andy ideas?
Regards,
Stefan

Hi Praven,
Copying all existing SendTo properties file to my project would be an option but I wouldn't win anything.
I'm quite happy with the existing SAP collaboraton properties files using e.g. for "Send e-mail".
I won't change this existing ones. I created a new LinkCommand. And for this new LinkCommand I'm looking for a solution how I can handle the translation for it.
I would prefer e using my existing file which is located in the KM. The reason why it's located in the KM is, if I need to change a translation or add a new translation properties file I only need to change it in the KM. If it's a part of the project I need by every change to deploy the project new.

Reading a properties file from BPEL Process (jar)

Hello,
I've created a .jar in which i have various classes and a xml file where i keep certain properties.
I have a BPEL Process in which i've embedded java code to access the classes in the jar.
I've created a folder in <ORACLE_HOME>/MyLibrary and added the jar. After, i've included this path to the domain.xml located in <ORACLE_HOME>/soasuite/bpel/domains/default/config into the property: "bpelcClasspath".
When i try to run the process, i get a "<BPELExecution::BPELProcess1> executing <exec> at line 251
java.lang.NullPointerException
at java.util.Properties.loadFromXML(Properties.java:700)
at com.gepe.ldap.LDAPConfiguration.readConfig(LDAPConfiguration.java:26)".
Apparently the properties file is not being found, am i correct?
How can i solve this?
Thank's in advance,

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???

How to read the properties file available in Server File structure in webdy

hi all,
I have developed one webdynpro application. In this application i need to access mdm server to continue. For getting the connection i need to pass the IP addresses.
Can i have code how to read the properties file which is residing in the server file. with out included along with the application. keeping some where in the file structure in the server. I want to read that properties file by maintain the iP addresses and users in properties file based on the key i want to read like below.
servername="abcServer"
username="john"
password="test123"
Please send me the code how to read this properties file from the file structure and how to read this values by key in webdynpro application
Regards
Vijay

Hi Vijay,
You can try this piece of code too:
Properties props = new Properties();
//try retrieve data from file
//catch exception in case properties file does not exist
try {
         props.load(new FileInputStream("c:\property\Test.properties")); //File location
         String serverName = props.getProperty("servername"); //Similarly, you can access the other properties
         if(serverName==null)
           //....do appropriate handling
     }     catch(IOException e)
               e.printStackTrace();

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.

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.

How do I read a properties file in WEB-INF without hard-coding a path?

Hello,
How do I read a properties file in WEB-INF without hard-coding a path?
I tried:
Properties properties = new Properties();
properties.load(new FileInputStream("db.properties"));
driver = properties.getProperty("driver");
but it cannot find the db.properties file.
Thanks for the help.
Frank

Don't use a File to read those properties.
Better to use the servlet context and
getResourceAsStream() method to get the InputStream.
It'll look for any file in the CLASSPATH. If you put
that properties file in the WEB-INF/classes directory
you'll have no problems, even if you deploy with a
WAR file.Completely agree with this approach. Just have to mention the following for completeness
according to the API,
"This method is different from java.lang.Class.getResourceAsStream, which uses a class loader. This method allows servlet containers to make a resource available to a servlet from any location, without using a class loader. "
So using this method, the resource can be anywhere under your web context, not just in the classpath.

Doubts in reading a '.properties' file

Hi All,
I have a doubt regarding properties file from which I am reading some key-values. Now I have few different keys (4-5) having same value .e.g.
key1=value1
key2=value1
key3=value1
key4=value1
key5=value1
Now I need to read these keys from different places and I also need to update the value to say 'value2' for all the keys e.g.
key1=value2
key2=value2
key3=value2
key4=value2
key5=value2
Now, since i need to update the values of all the keys, I am thinking of having another key-value pair (e.g. key=value1) in the same property file, and using the value of this key as value for all the keys displayed above. So that when I update the value of this key ( key=value2), I dont need to update the values of all the keys, since those keys will be reading the values from this key's value.
I hope i am clear with this explanation.... ;-)
My first question is, 'IS IT POSSIBLE' ???
If yes, then how????
Thanks in advance

The following little class is from my old bag of tricks:import java.util.Properties;
public class XProperties extends Properties {
     public static final String BEG= "${";
     public static final String END= "}";
     public XProperties() { super(); }
     public XProperties(Properties def) { super(def); }
     public String getRawProperty(String key) { return getRawProperty(key, null); }
     public String getRawProperty(String key, String def) {
          return super.getProperty(key, def);
     public String process(String val) {
          for (int i, j, n= val.length(); n >= 0 && (i= val.lastIndexOf(BEG, n)) >= 0 &&
            (j= val.indexOf(END, i)) >= 0; ) {
               String pat= val.substring(i+BEG.length(), j);
               String sub= super.getProperty(pat);
               if (sub != null) {
                    val= val.replaceAll("\\Q"+BEG+pat+END+"\\E", sub);
                    n= val.length();
               else
                    n= i-1;
          return val;
     public String getProperty(String key) { return getProperty(key, null); }
     public String getProperty(String key, String def) {
          String val= super.getProperty(key);
          return val == null?def:process(val);
}If you use an XProperties object instead of a Properties object
you can do the following in your .properties file:key= value1
key1= ${key}
key2= ${key}
key3= ${key}
key4= ${key}
key5= ${key}... if you want to change the value, all you have to do is change the
value of the 'key=value1' line.
kind regards,

Reading a properties file in a servlet and passing its contents to a JSP pa

Hi all,
I'm totally new to Servlet pgmg n JSP. Please can ne1 tell how to read a simple properties file (in a servlet) and pass its contents to a JSP page.Actually the reason is to fill a combo box in a JSP page with the contents of a properties file.If calling a servlet for the same is d best way to do that, plz can ne1 tell me :
1> whether to override the doPost method in the servlet in which to read d file using FileInputStream
2> Putting the contents in an array and then how to pass this array to the JSP page.
Thanks,

I'm using a properties file to let my web application know what the name of the database is. I'm using an abstract class GeneralDao which will be extended by all the DAO's (Data Access Objects or java classes containing SQL statements).
Here's the code :
protected Connection getDatabaseConnection()
          throws Melding
     Connection dbconn = null;
     ResourceBundle resBundle;
     try
     Class.forName("com.mysql.jdbc.Driver").newInstance();
     resBundle = ResourceBundle.getBundle("gcoConfig");
     String dbConnectie = resBundle.getString("databaseconnection");
     gcoLogger.debug("lezen databaseconnection in resourceBundle " );
     dbconn = DriverManager.getConnection(dbConnectie);
     } catch (InstantiationException exc)The ResourceBundle is used to read the properties file, named gcoConfig.properties.
With the getString() command I read the content of the string named databaseconnection.
The gcoConfig.properties file is placed inside the folder C:\Program Files\Apache Software Foundation\Tomcat 5.0\webapps\gco\WEB-INF\classes
The GeneralDao is placed in the folder C:\Program Files\Apache Software Foundation\Tomcat 5.0\webapps\gco\WEB-INF\classes\org\gertcuppens\cluifDao.
So this class is placed some folder below the WEB-INF\classes folder of gcoConfig.properties.
And the content of the properties file is just one line :
databaseconnection=jdbc:mysql://localhost/cluif
If you want to let the JSP know what's inside the properties file, wrap the content in a Javabean, put it in the request or even the session and pass the control to the JSP.

Reading external xml files from a jar

Hi,
I am trying to read an xml file from a jar (which is not present inside the jar ) .
I am passing the file name as a string (like C:/folder/filename) to the SAXBuilder but it throwing
unknown protocol: c error.
i tried using an url , tried using a relative path but to no use.
Need help in this regard urgently.
TIA,

Hi,
Actually, my application needs to read two xml files , parse it, perform some operation and write
the result to an output file.
The names of the two xml files i mentioned, are specified in a properties file as absolute paths. (I even tried converting them to URIs)
The xml files are in the same directory as the jar ( i dont know if it should matter as i am giving the absolute path).
The main class reads the names of the files and passes the names as strings to the SAXBuilder.
This is where i am getting an exception.
Going by what you said, is it not possible for a java class to read a fie outside of the jar ? Is there no way to do this ? And right now i am not sure of how to go about this or if there's any work around . Any help would be appreciated.
Kindly reply at the earliest
TIA,
Harsha

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!

Java.lang.NullPointerException in the code to read a properties file

I have written the following code to read a properties file...........

hi,
 If you are loading a resource (property) file from a jar file you can use
getResourceAsStream("com/test/test.properties").
 if the propery file is in outside of your jar file . you can use
Property portalProps = new Property ();
try {
 FileInputStream fileInputStream = new FileInputStream("<FilePath + FileName>");
 portalProps.load(fileInputStream);
 fileInputStream.close();
 } catch (IOException e) {
 //Log the error

Read a Properties File in a Static Floating Block

I am trying to read a properties file in a static floating block:
   static
      try
         Properties p = new Properties();
         String path = "/WEB-INF/classes";
         InputStream is = getClass().getResourceAsStream( path + "artimus_message_MessagInboxConfig.properties" );
         p.load(is); // load the stream into the Properties object
         WEBSITE_HOME = p.getProperty( "WEBSITE_HOME" );
         setWebSiteHome( WEBSITE_HOME );
      catch { ......}
   }I got a compilation error saying that the non-static method getClass() cannot be referenced from a static context. There is almost no way to make this static floating block non-static. What should I do?

Thanks for the reply. But, huh... I do not quite
understand. Which class is MyClass?It's a generic placeholder for whichever class your put that block into. You wouldn't put it there literally--replace it with the name of the actual class. If that block is in Foo.java, then use Foo.class instead of MyClass.class.
>
Okay, this static floating block is in a class called
MessageInboxConfig.java. Then use MessageInboxConfig.class.getResourceAsStream(...)
And inside this static
floating block, I am reading a properties file and
this properties file is in the
ContextRoot/WEB-INF/classes/artimus_message_MessagInbox
onfig.propertiesHow do I read this properties file?
Properties p = new Properties();
InputStream is = MessageInboxConfig.class.getResourceAsStream("artimus_message_MessagInboxConfig.properties" );
... etc. ...You shouldn't need to specify "WEB-INF/classes," since it should be in your classpath. What you pass to getResource is a path relative to a directory in your classpath.

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.
