Classpath and 3rd party jar files

We have been searching for a long time and have not been able to find an answer to our question. Do you think that you could help us out?
We need to include 3rd party jar files in our application. Where in the deployment classpath directory structure can we place these. This does not seem to happen when we publish.
We also need to give our clients the ability to modify our configuration. Currently we do this with an xml file, which we place under server/config in our JBoss directory. We also need to find a home for out log4J configuration file.
Where does this type of thing exist in the SAP world?

We have had problems with 3rd party jar files also. We ended up including them in the WEB-INF/lib directory of our WAR file and packaging/deploying them everytime.
If you are looking for your project on your server, it is deployed to a directory similar to this:
/usr/sap/J01/JC00/j2ee/cluster/server0/apps
Hope this helps.

How can I include 3rd party jar files with my custom extention?

I'm writing an extension that is dependent upon some 3rd party jars. How can I include/package these with my extension?
we're using the 11g tech preview
thanks,
Dylan

Do you mean that you need these files to appear in JDeveloper as a library available for the developers who build a project and use your extension?
You can create a library in JDeveloper with JAR files by simply adding the following to your extension.xml file:
<jdeveloper-hook xmlns="http://xmlns.oracle.com/jdeveloper/1013/extension">
- <libraries xmlns="http://xmlns.oracle.com/jdeveloper/1013/jdev-libraries">
<library name="My Extension Library">
<classpath> ${ide.extension.install.home}/lib/some.jar</classpath>
</library>
</jdeveloper-hook>

Applets and 3rd party jars

Hi,
I'm trying to use a 3rd party jar with an applet. I can access the functions just fine when using an applet viewer, but when I try deploying the applet from a web page I get classNotFound exceptions. How do I go about getting the applet to recognize the jar file?
Thanks

Eva, yes, if that class in one of the 3rd party jars wants to access your class directly, then it is necessary that your class is loaded by the same classloader that loads that 3rd party jar or even higher up the classloader hierarchy.
Why do you consider putting your class library into applib "a bit rude"? As long as your classes are named distinctively so that they will not clash with other classes, it is not a problem.
On the other hand, it seems that the design of that 3rd party class is not classloader friendly. Had it used something like the following to load a class that is undefined at the compile time, you might not have this problem.
Class userClass = Thread.currentThread().getContextClassLoader().loadClass(nameOfUserDevelopedClass);
Object plugin = userClass.newInstance();

"bc4j.xcfg" file not in classpath (and not in JAR file)

Hi, this is a very similar problem to one reported today. I have created a JClient application that connects to a DB and displays some info in a JFrame. Running the application through JDeveloper, all is fine. But, if I create a jar file and run it directly through the jar file, I get this error message:
C:\Work\Client\View\deploy>java -jar my_client.jar
oracle.jbo.JboException: JBO-33001: Cannot find the configuration file /combit/common/bc4j.xcfg in the classpath

In fact, the bc4j.xcfg file is not inside my JAR file (it belongs to the BC4J project, so when I created the JAR file for my "View" project, it never came into.
How should I create the JAR file to have this file inside and fix my problem??
Thanks a lot,
David

I'm having a similar problem -- but I am just trying to run the BC4J project -- not a project dependent on the BC4J components... where is the classpath being incorrectly set?

Using loadjava utility to load a 3rd party jar file

Hi Folks,
    I need to validate if a java class, stored into an Oracle Database, is able to connect to a SQLite database.
    In order to connect to SQLite I'm using the the jar file sqlite-jdbc-3.7.2.jar that I got from https://bitbucket.org/xerial/sqlite-jdbc/downloads
    Then I tried to load the jar file into Oracle Database using the command:
    loadjava -resolve -user system/xpto@tm014_23 -schema novacap sqlite-jdbc-3.7.2.jar
    The result is a series of error messages with the error code ORA-29533.
    Ex: - Attempt to overwrite class or resource org/sqlite/Codes while defining or compiling SYSTEM.org/sqlite/Codes
    Can you guys help me?
Thanks,
Luis

I need to validate if a java class, stored into an Oracle Database, is able to connect to a SQLite database.
You need to explain that a little more.
How could a java class within Oracle connect to a SQLLite database if the driver it needs isn't already loaded into Oracle.
The fact that you have to load the driver jar file tells you that the class will not be able to connect to SQLLite.
The recommended way to develop with 'Java in the database' is to first write and test the code OUTSIDE the database. Then when it works load it in the databse.
So use a copy of the Java class and test it outside the database to see if it can connect.
Also since 11g you could just load that jar as a 'database resident' jar file. If you don't do that then Oracle just extracts all of the files in the jar and tries to load them one at a time. So using 'resolve' won't work because Oracle isn't going to load the classes in the proper order.
See 'database resident jars' in the Java Dev Guide
http://docs.oracle.com/cd/B28359_01/java.111/b31225/chtwo.htm#BEJCBAHI
Database Resident JARs
Starting with 11g release 1 (11.1), when you load the contents of a JAR into the database, you have the option of creating a database object representing the JAR itself. In this way, you can retain an association between this JAR object and the class, resource, and source objects loaded from the JAR. This enables you to:
Use signed JARs and JAR namespace segregation in the same way as you use them in standard JVM.
Manage the classes that you have derived from a JAR while loading it into the database as a single unit. This helps you to prevent individual redefinition of the classes loaded from the JAR. It also enables you to drop the whole set of classes loaded from the JAR, irrespective of the contents or the continued existence of the JAR on the external file system, at the time of dropping it.
In order to load a JAR into the database, you have the following options of the loadjava tool:
-jarsasdbobjects
-prependjarnames
For more information regarding the loadjava tool options, refer to "The loadjava Tool" section.

How to use 3rd party jar files for xml transform

Hi all,
Am using OAS9.0.4 and I deployed my .ear successfully.
In my application am using 4 jar files for xml transformation. (xerces.jar, xalan.jar, xml-apis.jar,xercesImpl.jar)
OAS has its own xmlparserv2.jar file. Its using this jar file for transforming xml data and not even looking for above mentioned 4 jar files.
In opmn.xml, I provided these 4 jar files in to class path. Then also it didn't effect my output.
I also tried as put these 4 jar files into j2ee\home\applib directory, but o result.
Can anybody tell me where should I keep these 4 jar files in OAS and OAS should use these 4 jar files instead of its own xmlparserv2.jar for transforming data.
Thanks in Anticipation,
Regards,
RK

Add the Xbootclasspath variable in the java-options field. It will somewhat look like the following in your opmn.xml file
<process-type id="<OC4J Instance Name>" module-id="OC4J">
<module-data>
<category id="start-parameters">
<data id="java-options value="........... -Xbootclasspath^/a:<location of your jar files>" />
Ensure to use th ^/a (append) signature

Using 3rd party jar file in WCEM3.0

Hi,
I want to get data from an external database into WCEM. Is it possible to use MySQL connector jar for achieving this?
I used the MySQL connector jar but my guess is, it does not get deployed to the server. It is just visible in my local development.
When I try to connect to the database I get an error saying "could not find a suitable JDBC driver".
I need some guidance.
Regards,

Hi Steffen,
As per your suggestion I was able to ping the database manually, but when I try to access it from my code which runs on the server I am getting the exception that I have stated below.
But if I want to connect to the database dynamically, what then? I am using the MySQL connector jar file for this purpose but on deploying the code to the server I get the error as "Could not find a suitable driver".
I think the jar file is not getting deployed to the server. Are there any steps that I would have to follow to deploy it?

CLASSPATH issues on DOS/NT and loading of jar files

Hello all,
I have the following problem on running WebLogic 5.1 on
NT. The CLASSPATH is getting truncated after a certain number of
characters. I have a lot of third party jar files that I use in my
application. How do I overcome this problem ? I tried increasing my DOS
environment space by changing the default values in config.sys.
What are other alternatives ?
One idea that I have is to use URLClassLoader to load the jar files. I
am running a RMI based application and I need to load these jar files
before I load the RMI code. Where would I run this URLClassLoader code
? Is there some system startup class that can load jar files ?
Thanks,
Aswin.

Thanks for the reply. I much appreciate it. What about the other idea that I
had outlined-loading these jar files using a ClassLoader. Is that viable ?

You still will not be able to have a command line exceeding a certain size
(around 1k or so). That is a hardcoded limit somewhere inside the NT kernel
("kernel" being a poor term for the piece so named in NT ;-).

Problem deploying new version of 3rd party jar

I have a third party jar file that was recently updated with to a new version. I deleted the old jar file and replaced it with the new version. Modified classpath accordingly. The strange thing is that the only way I could get the classes that use this jar file to work was to recompile them. What am I missing?

When replacing a jar file it is alway a good idea to recompile against it... this ensures backward compatibity and also prevents Incompatible Class Change Errors. Your new 3rd party jar may not be completely backwards compatible, although it is always a good idea to recompile when implementing a new jar that your application depends on.

How to include third party .jar files into my jar file

Hi,
how do i include a open source third party jar file into an executable jar?
i have a class called BlogBox.java and it uses org.apache.commons.net.ftp.FTPClient, i want to create an executable file, where do i put the .jar file containing FTPClient aka Apache Commons Net?
currently i'm getting the following error from when executing my BlogBox.jar
C:\MyJava\BlogBox>java -jar BlogBox.jar
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/net/ftp/FTPClient
at blogbox.BlogBox.<init>(BlogBox.java:27)
at blogbox.BlogBox.main(BlogBox.java:103)
Any suggestions? i have searched google and this forum but could not find the solution to my problem, thanks
[edited msg] do i need to add the classpath at execution or something of the apache commons net library?

When you use an executable jar the normal class path
is ignored, but you can put a classpath inside the
jar. The usual trick is to place the library jar
files in a directory inside the application directory
and direct the manifest file to it. The manifest file
live in the jar inside the META-INF directory and
it's called manifest.mf
The two heavilly used entries are Main-class: and
Class-path: lines. Class-path just has a
comma-separated list of library paths.
The jar utility has a special option to load it up.Thanks :) I created a "/lib" directory, placed in the packages in there and redirected the Class-Path: lib/commons-net-1.4.1.jar
and it works,
thank you everyone :)

Where should the third party JAR files be placed ?

Hi,
We have a requirement to perform encryption / decryption of supplier bids. In this case we require to use third party provider JAR files with OA framework code. Where should the JAR files generally be placed in such a scenario ?

Question about using third party jar files in Java Web Start Environment

Hi everybody, I got a very strange problem and still can't figer out how to solve it. Can anyone help to overcome this problem?? Thanks in advance.
Question: I wrote a simple java swing application to connect to Oracle database. I packed whole my classes and a third party jar file(classes12.jar) to a new jar file named "IRMASSvrMgntGUI.jar" and then use command 'jarsigner' to signed IRMASSvrMgntGUI.jar. There is no problem when I execute 'java -jar IRMASSvrMgntGUI.jar' in the command line. But when I execute this application via Web Start Environment, an "java.lang.NoClassDefFoundError: oracle/jdbc/driver/OracleDriver

contents of the manifest file I used to create this jar file are as follows
===================================
Manifest-Version: 1.0
Main-Class: IRMASSvrMgntGUI

===================================
and file structures in "IRMASSvrMgntGUI.jar" is
====================================
META-INF/
classes12.jar
DBAuthenticateDialog.class
DBConnection.class
IRMASSvrMgntGUI.class
====================================

If you directly include classes12.jar in IRMASSvrMgntGUI.jar, the classloader won't be able to find the classes inside classes12.jar. You should sign classes12.jar separately and include that in jnlp along with your application specific jar. When you're launching your app using "java -jar somefile.jar" then the classpath settings in manifest file are used, but that's not the case when you start using JWS since in this case the classpath is based only on the " <jar href=..." entries in jnlp.

Hi Sudhindra,
you can put them in your EAR (on top level or you can create a
directory
for them, like "libs" or sth.), and then create class-path entriesin
the manifest files of your WAR and ejb-jars.
Example: if myApp.war needs myUtil.jar, then write a line
Class-Path: myUtil.jar
in the manifest file of myApp.war. If myUtil.jar is in libs, write
libs/myUtil.jar and so on.

Signing of 3rd Party jars

I have developed an app which uses Java Web Start. I created a self signed certificate for now an that works fine.
What I was wondering about was 3rd party jars. Are they responsible for their own signing if they do system or disk I/O? Do I need to contact the vendor to get a signed version? I don't think I should be signing someone elses archive files.
I need to run with all permissons set.

My understanding is that if you sign one jar, you need
to sign them all (and with the same certificate).This is only true within the the same jnlp file - not within the whole app.
You can factor out sets of jar files into component extenions (a seperate jnlp file referenced by the original jnlp file.)
Each component extension can have or not have the all-permissions tag, and if it does, the set of jar files in it can be signed by the same or a diferent certificate chain than the original.
