EJB newbie - ant question

Hi,
This is an ant question. Hope it is ok for me to ask this here.
I have a windows xp machine.
I have ant installed in C:\libraries\apache-ant-1.6.1
ANT_HOME=C:\libraries\apache-ant-1.6.1\
PATH has C:\libraries\apache-ant-1.6.1\bin
ANT home is a system variable.
Inspite of this, I am not able to use ant.
I get the following error. Am i missing something?
ANT_HOME is set incorrectly or ant could not be located. Please set ANT_HOME.
Thanks,
Suma

Hi !
please do the following
1. go to the desktop and right click on the mycomputer and select properties
2.click advanced tab on the properties
3. then click on the environment variables.
then in the environment variables choose path for the system variables
in that path
suppose you installed ant in c:\libraries
edit path: c:\libraries\ant1.6.1\bin;.;
and also go to the systemvariable classpath
and edit classpath as
add this
c:\libraries\ant1.6.1\lib;.;
then close the properties box
open the command prompt
and type ant
definetly it will work...

Newbie ANT question

as my codebase is growing, and the number of applications within in are increasing I figured it would be a smart move to switch to using ANT, but I am having a bit of trouble configuring it to work the way i would like. I have read several tutorials, but they dont seem to get into enough detail.
Basically, all I want to do, is compile only specific packages related to an application, and then run the main method of that application.
In addition, I want to jar up those specific packages only.
Since, I have several large applications all under the same root
directory, I figured this would help reduce compile time, and allow me
to be a bit more organized.
If anyone could give me some hints, or point me in the right direction. I
would appreciate it!
thanks!

so I am trying something like this:
<target name="jar" depends="dist" description="generate the jar" >
<jar destfile="${dist}/app.jar">
<fileset dir="${classes}/com/domain/package1"/>
<fileset dir="${classes}/com/domain/package2"/>
</jar>
</target>
What I want is a new jar file which has all the classes in these directories (recursively).
But I also want to maintain the directory hierarchy. i.e. com/domain/package1...but I cant figure this out, and all of the subdirectories from package1 & package2 are on the base level.

General place for newbie datamodeler questions?

With the production release of SQL Developer Data Modeler I'd assume that this forum will draw a bunch of new users. Is there a better place to ask some pretty simple, newbie like questions that won't bother the more seasoned members?
For instance, I am working in a Rails environment, which has some stringent naming conventions, one of which is that all of the primary key columns are numeric and called "id", with the foreign key linked columns called <table_name>_id. When engineering a logical model to a relational model, the added foreign key columns are all "id#". Is there a way I can define a naming rule to keep me from having to redo the relation column names?
Also, we have a standard set of columns (mostly Rails related) which appear in every table. Can I define a generation rule which automatically includes these tables?
Thanks

Thank you. I will try changing that setting.
IS there a setting which tells the relational model to automatically create pk and fk indexes? I haven't seen one, and manually setting them up is a tedious task. --sw

Newbie script question... consecutive numbers with update.

complete newbie type question... this is also my first post. ( I am using CS3)
does anyone have a script which can make it so I can add numbers into the text consecutively.
for example, if this is my text "the big fat dog sat on the very wide mat, but was then displaced by a unfriendly cat."
and I wanted to place a number 1, number 2, 3, etc at points in the text so it read, "the big fat dog1 sat on the very wide mat2, but was then displaced by a unfriendly cat3." but later wanted to add another number and have later numbers update themselves, so the text then said, "the big fat dog1 sat on the very wide mat2, but was then displaced3 by a unfriendly cat.4".
by inserting the three, the previous three became four.
Has anyone got something which might be useful in this regard.
Many thanks
Steve

i wanted to avoid footnotes as they leave a bar at the bottom of each page.
i wanted a script to do something similar to footnotes but not much further.
does anyone have just a simple script that can do what I asked?

Newbie XSan question - authenticating a computer from XSan Admin

Hello - I have a very newbie XSan question!
I have 2 computers that connect to an XSan. 1 I am having no problems with. The other I am unable to connect with.
When I look in XSan Admin the 2nd computer (the one that is not working) is not authenticated.
So I click on it and choose Authenticate. I enter what I know is an Admin username and password for the computer I am attempting to connect. The dot next to the computers IP turns green with 3 dots in it and then it turns gray again. It just does not connect.
What is the problem?
Is it licensing?
Thanks
Taj

You need a different license ID for each machine, plus the admin machine. Do you have that?

EJB Newbie Question

I am totally new to EJB and I have gone through Sun's tutorial at http://java.sun.com/j2ee/tutorial/1_3-fcs/doc/GettingStarted.html and I've got everything in the tutorial working with the Sun J2EE server installed on my computer. They teach you how to write a bean and call it from a client application and from a .JSP page using the web server installed with J2EE on port 8080. Now, I want to call it from my ColdFusionMX page using the CFMX web server and I can't figure it out. Can anybody help me? I'm not sure what I need to do in CFMX to get the Java bean to work. I realize this is also a question for the ColdFusion community, but I'm sure connecting from ColdFusion is not very much different than from other languages.
I created a very watered down ColdFusion version of the JSP page provided by Sun in the EJB tutorial. However, it looks like the JNDI lookup is not working for some reason. I think the problem is that I need to specify that the lookup will occur on my JNDI port, which is 10500 on my local host. It looks like it is trying to use a ColdFusion JNDI service that does not have the EJB installed or something like that. I would appreciate some code samples of how to get this to work. I can't find any good sites that give you a walk through of how this is supposed to work.
Keep in mind this does work when I call the .JSP version of this page through the J2EE web server. The trick is for me to get this working in ColdFusion.
Thanks everybody!
Jon

Building weblogic ejbs with ant...

Hi, it may be not the proper place, but I haven't found a better one...
Here comes my question:
I have an ant build.xml file where I have the following tasks defined:
<property name="ejb.dtd.location" value="weblogic/ejb/deployment/xml/ejb-jar.dtd"/>
    <condition property="ejb.dtd.location" value="weblogic/ejb20/dd/xml/ejb11-jar.dtd">
      <equals arg1="${weblogic.major.version}" arg2="6"/>
    </condition>
    <property name="weblogic.ejb.dtd.location" value="weblogic/ejb/deployment/xml/weblogic-ejb-jar.dtd"/>
    <condition property="ejb.dtd.location" value="weblogic/ejb20/dd/xml/weblogic510-ejb-jar.dtd">
      <equals arg1="${weblogic.major.version}" arg2="6"/>
    </condition>

<target name="compile.ejb" depends="init">
    <javac srcdir="${srcDir.ejb}"
          destdir="${srcDir.ejb}"
            debug="${npm.debug}">
      <classpath id="ejb.cpath">
         <pathelement path="${weblogic.sp.path}"/>
         <pathelement path="${weblogic.core.path}"/>
         <pathelement location="${outDir.core}${file.separator}npm.jar"/>
         <pathelement location="${srcDir.ejb}"/>
       </classpath>
    </javac>
</target>

<target name="make.ejb" depends="prepare, compile.ejb">
    
    <ejbjar srcdir="${srcDir.ejb}">
       <weblogic destdir="${outDir.ejb}"
                 compiler="${compiler.ejb}"
                 keepgeneric="false"
                 suffix=".jar"
                 args="-g -nowarn"
                 oldCMP="false">
         <classpath refid="ejb.cpath"/>
       </weblogic>
       <include name="**/*-ejb-jar.xml"/>
       <exclude name="**/*-weblogic-ejb-jar.xml"/>
       
       <dtd publicId="-//Sun Microsystems, Inc.//DTD Enterprise JavaBeans 1.1//EN"
            location="${ejb.dtd.location}"/>
       <dtd publicId="-//BEA Systems, Inc.//DTD WebLogic 5.1.0 EJB//EN"
            location="${weblogic.ejb.dtd.location}"/>
    </ejbjar>
</target>This should build my ejbs with either the wls61 ejbc or the wls51 one. Anyway ant seems to have problems finding the local dtds in the classpath, although this is specified in the documentation. When I set both location attributes to point to files it works perfect. The problem is that these are in weblogic.jar for the wls61 release. This has two solutions, but either are bad in my opinion:
1. extract the needed dtds to a temp dir with a jar task and then delete em...
2. put the proper wls.jar in the classpath so ejbc could automatically resolve the dtds
Can anyone help or may be send his ant build file, where a <dtd> nested element is used for <ejbjar> for wls61?
Thank you in advance
Anton

Anton,
Your second solution is the correct one. If you look at dtd element description under ejbjar task in the Ant manual, you'll see that vendors jars are required in Ant's classpath in order for ejbjar task to resolve DTD dependencies, in which case you don't need to specify dtd elements. I don't particularly like it either. If you find a better way to solve this problem, let me know.

This Newbie Has Questions

Hi there. I am a newbie to Apple. I purchased the iBook last month and of course, when the MacBook (which had the features I wanted) came out, I rushed out and got one and I'm very pleased with my purchase - but I have a few "newbie" questions:
1) Printing on a PC based Linksys seems to be a nightmare. I can't get anything printed on the shared HP 2600N and HP1012 printers. I literally have to disconnect them from the PC and plug the USB directly to my MacBook to print. It seems like there should be a better, easier and MacFriendly way of doing this - anyone have an easy solution?
2) I'm going to purchase Windows XP so I can run my windows programs on this computer. Does anyone have any pre-installation advice?
3) I have a blackberry device that worked fine with my iBook, but does not work with my MacBook - any suggestions or is there a software compatibility patch?
4) I transferred everything from my old Mac to my new Mac with no problem. How can I migrate my contacts from Entourage to the Address Book?
5) I notice that sometimes the MacBook "stalls" or doesn't work fast in some functions...is it just me - I expect the machine to jump quickly...but sometimes I get that annoying pinwheel when opening programs.
Thanks for your help!

The problem is probably a driver issue.
Printing to a printer on a XP PC from a Mac running 10.4.x
http://www.ifelix.co.uk/tech/3015.html
You may need to use a third-party driver such as the HPIJS drivers or the Gimp-Print drivers, but this is not the case with all printers.
2) I'm going to purchase Windows XP so I can run my
windows programs on this computer. Does anyone have
any pre-installation advice?
Ensure you get a full version (not an upgrade version) and it comes with XP SP2 already.
Do not install Boot Camp on a critical machine and make regular backups of your data, this is beta software and there are bugs and issues.

Are these Universal or PPC only applications?

Newbie wireless question (slightly off-topic)

I didn't want to post this here as it's not entirely an Airport-specific question. I posted this to the iBook forums, but nobody there has answered so my apologies if this is not welcome here. (Any moderators can remove it if that's the case.)
I've been using computers extensively for over a decade, but I'm a total newbie to wifi. I just set up a wireless network in my house and would appreciate some advice/feedback.
My main concerns are whether or not my network is reasonably secure. I know there is no such thing as perfect security, but I don't know if what I've done is good enough or not.
I don't have an Airport base station, but I do have a D-Link Airplus G and an Airport card in my iBook. I have WEP set up on the router and I have enabled MAC filtering, listing only my desktop and my iBook, excluding all others from the network.
I'm fairly certain that nobody in my neighborhood is going to get into my machines this way or be able to sniff my network data stream, but am I right in assuming that nobody can "piggyback" on my Internet connection too? Presumably, if everyone but my own machines are MAC-filtered and kept out, then the Internet connection is also protected. Is that how it works?

WEP and MAC filtering are better than nothing, but you can do better. These are my suggestions:
1. Use WPA with a pre-shared key (PSK) and TKIP encryption on your Netgear router, along with an alphanumeric passphrase of at least eight characters not found in any dictionary. The equivalent setting on your Mac is "WPA Personal". Unlike WEP security (which an expert can crack in under half an hour), WPA security is currently unhackable by any practical means as long as you use a non-dictionary passphrase. One last point - WPA security requires all your wireless Macs to be running MacOS 10.3 or newer.
2. MAC filtering is (these days) essentially useless as a wireless security method. Using "packet sniffing" of traffic on your wireless network to find out what MAC addresses are used by computers on your network, and a PC that allows its MAC address to be cloned so that it is identical to the MAC address of one your own wireless computers (which is possible with most PC wireless network adapters) even an amateur hacker can defeat MAC address filtering in minutes.
By the way - I don't think your posted message here is off topic. In my opinion, the Airport discussion forums are the best place to post any questions related to usage of wireless networks. Questions of this nature are virtually never specific to any Mac model.

Best Practice EJB 3.0 Question

I have a web application consisting of 3 projects:
- Model (EJB 3.0 Session Beans connected to two different databases)
- TagLibrary (custom tag library)
- ViewController (Web App / GUI)
Currently I am connecting to the EJB Beans using code that Jdeveloper generates for a test client:
env.put( Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory" );
env.put(Context.PROVIDER_URL, "t3://localhost:7101");
However would like to move these to a properties file (I believe jndi.properties) such that they can be modified based on app server.
My question is following:
What is best practice for Session beans in the Model project to access other session beans in the same project? Do I also need to specify JNDI prop file and settings? (This occurs when Bean from one database needs to access bean from another database).
Or should I really put these in two separate projects / EJB libraries?
Thanks,
Kris

You have two options, first is to use JNDI lookup (you should be able to use just new InitialContext(), without the environment map).
Second one is more elegant and, as far as I'm concerned, should be referred to as best practice, that is using dependency injection:
@EJB
YourSesionBeanInterface yourEJB;
If you get stuck, there is plenty of documentation about this on the internet.

Ejb deployment - classloader question

Hi Guys
I have a very basic question regarding EJB deployment in Weblogic 6.1 sp2.
Is it possble to create an EAR file such that -
1>it contains a WAR file [of servlets/jsps/client classes] - A
2>a jar file containing our core server classes[not EJBs] - B
3>a jar file containing EJBs - C
here A and C are definitely getting loaded by different class loaders - I want
the classloader for B to be parent of the classloaders for A and C - so that both
A and C can see B. - is this possible by some EAR/Weblogic specific way.
OR
the best solution is to place the B in the main classpath and deploy the C and
A in an EAR?
thanks

A and C can see B. - is this possible by some EAR/Weblogic specific way.Made possible by placing B in the ear at the root level and referring to B with the
Class-Path manifest directive in the ejb jar file for C. This will put B in the ejb
classloader's classpath making it visible to C and to A since the classloader for C
is the parent of the classloader for A. Which, is the recommended way.

This works, but the classfiles in B are now static for the uptime of the server. If
you want to make changes in B, you must restart the server. If you configure it the
way described above, you can reload the B classes by redeploying the application ear.

my persistence.xml is in the classes/META-INF directory("classes" directory is in the classpath).My persistence.xml is shown below.
<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence" version="1.0">
     <persistence-unit name ="FormStorePersistenceService" transaction-type="RESOURCE_LOCAL">
          <class>com.spireline.fs.appserver.kernel.dao.publication.Publication</class>
          <provider>oracle.toplink.essentials.PersistenceProvider</provider>
          <properties>
     <property name="toplink.jdbc.driver">com.microsoft.sqlserver.jdbc.SQLServerDriver</property>
     <property name="toplink.jdbc.password">narsi40</property>
     <property name="toplink.jdbc.username">narsi40</property>
     <property name="toplink.jdbc.url">jdbc:sqlserver://testdb:1433;databaseName=narsi40</property>
     </properties>
     </persistence-unit>
</persistence>
It looks like the processes throws a nullpointerexception when it is parsing the above persistence.xml file and for the life of me i can't understand why !!!?
Also i am bit baffled that it is trying to look for hibernate classes as it does specifiy
*"org.hibernate.ejb.HibernatePersistence" as its provider, even though i have specified toplink as the provider in the persistence.xml. Can somebody explain what is happening here.*
Thanks in advance
Narsi

I have already tried to google smack it..with no luck of course. Will post this in the hibernate forum.
Thanks

Newbie saving question in Illustrator

I know this is a newbie question. I designed a logo in Illustrator. Is there a way to save just the logo for exporting into other applications (ie Pagemaker or Photoshop) without having the white artboard?
Thanks
Brad

I don't know Pagemaker but with Photoshop I simply select all, copy and then paste in Photoshop - transparency will be maintained. If you paste as a Smart Object you retain the ability to edit the Illustrator artwork in Illustrator and update the PS file.

Basic Ant Question

Any Ant experts out there? This is such a basic question and I'm surprised it's not attacked point-blank in the Ant docs. I must be missing something.
I'm trying to use ant to build a makefile that can be used on both Unix and Windows. Basically the only difference between the two environments will be the name of the company root directory (designated by the environment variable CAEROOT which is defined under both OS's).
How can I access that environment variable with ant??? The obvious attempt shown below doesn't work because I guess Ant thinks it's a property.
<code>
<project name="XMLDBBridge" default="compile" basedir=".">

<property name="src" value="src"/>
<property name="build" value="classes"/>
<property name="caeroot" value="${CAEROOT}/"/>
<target name="init">

<tstamp/>

<mkdir dir="${build}"/>
</target>
<target name="compile" depends="init">

<javac srcdir="${src}" destdir="${build}" classpath="${caeroot}/JLib/OracleJDBC/;
${caeroot}/JLib/OracleXDK/lib/xsu12.jar"/>
</target>
<target name="clean">

<delete dir="${build}"/>
</target>
</project>
</code>

In case anyone else ever has this same problem.
I finally figured out how to get environment variables working in ant. It's quite nice but doesn't really figure anywhere in the docs even though I feel its one of the key usages for ant.
<code>
<project name="XMLDBBridge" default="compile" basedir=".">

<property name="src" value="src"/>
<property name="build" value="classes"/>
<property environment="envvar"/>
<target name="init">

<tstamp/>

<mkdir dir="${build}"/>
</target>
<target name="compile" depends="init">

<javac srcdir="${src}" destdir="${build}" classpath="${envvar.CAEROOT}/JLib/OracleJDBC/;
${envvar.CAEROOT}/JLib/OracleXDK/lib/xsu12.jar"/>
</target>
<target name="clean">

<delete dir="${build}"/>
</target>
</project>
</code>
