Bean works slow than a Java class

Hi,
I am trying to zip a file using beans that gets the parameters from jsp. I tried the same block of code as a Plain java class it does the zip action very fast but the same code when executed with bean does the zip action very slow, can some body tell what would be the problem.
thanks.

With other words, the network speed/bandwidth is the bottleneck.
A decent HDD can reach 70MB/s. A 10Mbit network won't go any faster than 10MB/s. Upgrade to 100Mbit, 1Gbit or optic fiber.

Illustrator CS4 working slower than CS2

Hi all,
I am working with a PDF file in Illustrator CS4, when I try to scroll with my hand tool it takes forever for the image to refresh and update to the new location. But when I work on the same PDF file in Illustrator CS2, scrolling with the hand tool is fine and the image updates to where I move it to really fast. The I checked the Units & Display Performance in both versions and they appear to be the same. Is there any other thing that I could try to make the PDF update faster in CS4? Thanks in advance.
pwitman

Hello Pwitman,
You are experiencing a CS4 Critical Bug. This CS4 version came with very serious and critical bugs (like the Memory Bug, Crop Marks, Icon Preview. Text spacing, etc, etc, etc.) that Adobe wont care to fix.
May that is why you have not receive a direct answer. The hole program can crash for one font that the CS4 version considers as a corrupt font (even when other programs or older versions can use the same font).
That is why CS2 is more reliable than the "new" version CS4. Adobe is going from bad to worse. I cannot wait to see CS5's bugs that Adobe wont fix.
I made the mistake of buying CS3; and now I do things in CS2 that CS3 or CS4 cannot do. Yep the old version can do things better than CS3 and CS4.
So where is the CS4 update? Well, Adobe will sell you CS5 as an update.

How to get properties of a bean from another java class

Hi,
I am new to JSF. Currently I am facing a problem, and hope you experts can give me some guidance.
The JSF app i am working on has one Java class for handling a tree structure, MyTreeNode.java, and it also has a bean, NameBean.java, which has two properties, username and password.
I can easily associate an input text with the #{name.username} to store the user's login... but later on, I need to fetch that information inside of MyTreeNode.java. How do I do that? Thanks!

Zimbra 8.0.3_GA_5664.FOSS mail in and out become slow than usual.

Hi,
I am using zcs 8.0.3_GA_5664.FOSS. Few days back i observe that my server working slow than usual. I found that zmconfigd not runnig or sometime running but mail input and output is slow. I google the issue and some people said to change/disable the line /etc/hosts ipv6 line ":: 1     localhost.localdomain........". I did that but still slow.
Can anyone suggest to speed it up like before.

Encounter 64 bits work slower then 64 bits

The application i have when compiled in 64bits work slower than 32 bits.
Observed there are some site making the same claim.
Are there any mitigation can be made ?

Hi
There are lots of issues in 32bit vs. 64 bit performance.
If you need to access a lot of memory (4G and over) then you have no choice, you must use 64bit apps.
Next, if you are using amd64, then in 64bit code it has more CPU registers available, which can make it significantly faster than 32bit code.
Counting against 64bit code is the fact that the larger size of longs and pointers means that there can be fewer of them in the caches, so there will be a lower cache hit rate.
64bit code is able transfer data more quickly (64bit data path), but at the same time needs to transfer more data (64bit pointers and longs). No idea what the balance is for this, plus I suspect that most 32bit CPUs these days already use a 64bit external data path.

Difference b/w Java Class and Bean class

hi,
can anybody please tell me the clear difference between ordinary java class and java Bean class. i know that bean is also a java class but i donno the exact difference between the both.
can anybody please do help me in understanding the concept behind the bean class.
Thank u in advance.

While researching this question, I came across this answer by Kim Fowler. I think it explains it better than any other answer I have seen in the forum.
Many thanks Kim
Hi
Luckily in the java world the definition of components is a little
less severe than when using COM (I also have, and still occasionaly
do, worked in the COM world)
Firstly there are two definitions that need to be clarified and
separated: JavaBean and EnterpriseJavaBean (EJB)
EJB are the high end, enterprise level, support for distributed
component architectures. They are roughly equivalent to the use of MTS
components in the COM/ COM+ world. They can only run within an EJB
server and provide support, via the server, for functionality such as
object pooling, scalability, security, transactions etc. In order to
hook into this ability EJB have sets of interfaces that they are
required to support
JavaBeans are standard Java Classes that follow a set of rules:
a) Hava a public, no argument constructor
b) follow a naming patterns such that all accessor and modifier
functions begin with set/ get or is, e.g.
public void setAge( int x)
public int getAge()
The system can then use a mechanism known as 'reflection/
introspection' to determine the properties of a JavaBean, literally
interacting with the class file to find its method and constructor
signatures, in the example above the JavaBean would end with a single
property named 'age' and of type 'int' The system simply drops the
'set' 'get' or 'is' prefix, switches the first letter to lower case
and deduces the property type via the method definition.
Event support is handled in a similar manner, the system looks for
methods similar to
addFredListener(...)
addXXXListener
means the JavaBean supports Fred and XXX events, this information is
particularly useful for Visual builder tools
In addition there is the abiliity to define a "BeanInfo' class that
explicitly defines the above information giving the capability to hide
methods, change names etc. this can also be used in the case where you
cannot, for one reason or another, use the naming patterns.
Finally the JavaBean can optionally - though usually does - support
the Serializable interface to allow persistence of state.
As well as standard application programming, JavaBeans are regularly
used in the interaction between Servlets and JSP giving the java
developer the ability to ceate ojbect using standard java whilst the
JSP developer can potentially use JSP markup tags to interact in a
more property based mechanism. EJB are heaviliy used in Enterprise
application to allow the robust distribution of process

Is that Jasper Exception telling us where the problem is in the jsp, though?
If it is, then "rs" is null in the call rs.next()...which means conn.executeQuery() is returning null. Which means that whatever class conn is (news.conn?) has a problem maybe?That's possible. Though, it may just be the case that the 'conn' object itself is null! That line is the first place where it's being used and there are no checks that I can see...we'll have to wait for the OP to investigate and reply I guess.That's what I originally thought, then I noticed it was saying line 47, which is the rs.next() line. Assuming Jasper is correct in its choice of line, then it's the rs that's null. Which means the conn is doing strange things.
Edit: Now that I think about it, going by the previous thread the OP posted, I'm wondering whether news.conn class is their attempt to move the JDBC stuff out of the JSP page, and it's grabbing the "real" connection (java.sql.Connection) and getting the result set and returning it...or getting something wrong and returning null.

In terms of scalabilty, will static method in normal java class better than

You only have one copy of the static method in memory, but you have a few copy of the stateless session bean, plus the overhead of those session bean.So isn't static method of normal java class more scalable than stateless session bean.

Then you have to take care of transaction management, connection pooling, etc other ejb services all by your self.
In fact stateless session beans acts more like a static class. They do not get destroyed when remove() method is called on client stub. Similarly they are not always gets created whenever someone calls create() method on home interface!! (Again it's specific to appserver implementation)
Thx.

StreamCorruptedException from Stateless Session bean to java class

Hi all,
We have 2 servers, a ColdFusion App server which contains suns jdk 1.4.2 and websphere appserver using Ibm jdk, 1.4.2. On Server 1, we have a standalone java class which does a stateless session bean lookup and requests a service from it. On server 2(websphere), we have a stateless session bean deployed which connects to a database using a jndi lookup, executes a query and returns back a CachedRowSet object (which populates the ResultSet from the above query.) In some cases, session bean returns back an array of objects or String objects or just plain int values.
When the java class on server 1 invokes the methods returning CachedRowSet, we are getting a StreamCorruptedException, whereas on the server side, there is no exception. everything gets executed fine on websphere. This is the case only for CachedRowSet and not for other return types(as mentioned earlier the session bean returns an array of object in some cases which the java class on server 1 is successfully able to use).
This is what the piece of code look like on server 1:
// First gets a StatelessSessionBean using suns InitialContextFactory
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.cosnaming.CNCtxFactory");
env.put(Context.PROVIDER_URL,"iiop://localhost:2809");
System.out.println("Creating initial context");
Context ctx = new InitialContext(env);
System.out.println("Initial context created.");
Object homeObj = ctx.lookup("cell/nodes/localhost/servers/server1/ejb/SSBHome");
SSBHome eHome = (SSBHome)PortableRemoteObject.narrow(homeObj,SSBHome.class);
System.out.println("Got Home");
SSB eBean = eHome.create();
CachedRowSet crs = eBean.getAccts(param1, param2);
//This is the line of code which throws the exception.
The stacktrace shoows as follows:
Got Home

Again, everything seems to work fine on websphere server.
Any Clue of why this is happening?
All suggestions are greatly appreciated.
Thanks

Sorry for the confusion!
The solution mentioned above is not the right solution.
The above given code works fine irrespective of having corbaloc in the url, if you are working in the IBMs jvm.
It fails if you are working in suns jvm.
Anyone with any idea whats missing here.
Thanks a lot for any suggestion/ideas

Call Bean from normal java class

Dear Friends,
Is it ok to call an entity bean or session bean frm normal Java class.
(Java class is in the same application as the beans).
Is there a special way to lookup the beans from normal java classes.
Thanking You,
Chamal.

it is ok and very commonly done.
Note that the simple java program must be running in the same local network. You cannot have the java program and EJBs distributed over internet. (I m not certain of it, but mostly I shoudl be correct. If you have the resources, try it out and let me know)
In most of the cases, EJBs are called by
1. A servlet
2. Another EJB
3. a simple java program.
In the first 2 cases, you can go for Local Interfaces (more so in the second case than the first). The reason being that the the client and server will be in the same JVM (typically the Application server). Thus, in the first case, if the Web container and the ejb container are in the same app server, EJBs can be local.
However, in the third case, it is unlikey that you will have the client runnng and the same jvm as the server, because the app server has its own jvm.
sample code (this method is being called from the main method of a simple java program. it is self explanatory):
public void processRequestForSessionBean()
         System.out.println("REQUEST RECEIVED");
         try
               Hashtable nameHashtable = new Hashtable();
               nameHashtable.put( Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory" );
               nameHashtable.put( Context.PROVIDER_URL, "t3://localhost:7001" );
               InitialContext context = new InitialContext(nameHashtable);
               System.out.println("created initial context");
               Object lookupObject = context.lookup("CustomerBean");
               System.out.println("Got the lookup object");
               CustomerDataHome home = (CustomerDataHome) PortableRemoteObject.narrow(lookupObject,
                         Class.forName("com.shiv.business.CustomerDataHome"));
               System.out.println("Home interface");
               customerData = home.create();
               System.out.println("Remote Interface");
               addDataToSB(customerData);
               ArrayList namesList = customerData.getNames();
               System.out.println(namesList.toString());
               //customerData.remove();
          catch (Exception exception)
               System.out.println("FATAL ERRORS");
               exception.printStackTrace();
          }

XSLT Mapping with Java class not working in Integration Repository

Hi,
I have an XSLT mapping program with Java enhancement and I was able to successfully tested it in Stylus Studio. However, when I imported the Java class and the xslt program in Enterprise Service Builder and tested it, my program does not compile.
Here is the error message: "Transformer Configuration Exception occurred when loading XSLT mapping_temp.xsl; details: Could not compile stylesheet".
My java program is in a zip file containing SOAPHeaderHandler.java and SOAPHeaderhandler.class. My Java has a package com.nga.xslt.
Here is the declaration of my Java class in the XSLT: xmlns:javamap="java:com.nga.xslt.SOAPHeaderHandler"
It seems that it could not read the java class. Can you please advice what is wrong?

Hi ,
select XMLTOOLKIT option in Operation mapping and execute it.
I am not sure we can call java program in XSLT Program,but alternative is copy the code and use it in XSLT mapping it self,that means your XSLT program will become with JAVA extensions.
then in Operation mapping level select SAPXMLTOOL kit option and execute it. i hope it will work. if it is not working then you have deploy some JAXP files on server,because the way execution of XSLT Mpaping program got changed,like when eve you executing XSLT with extnasions( if you are not using XMLTOOL kit option) then you have to use latest version of JAXP.JDK files.

Than how can i get java class by using it's class file?

Hi
After compilation of a java program, it creates a class file.
After getting class file suppose class file has been deleted.
Than how can i get java class by using it's class file?
Thanks in advance.

get a decompiler and run your class file through it--I'll assume you want the source code back and that you are not trying to recover a missing class file by attempting to use the class file that is missing--if it's missing, then I've not a clue on how to get it back by using what is already missing.
BTW: many of your compilers have source control--if it does, just restore your missing file.

Any difference in creating a web service from a java class or session bean?

Hi,
The JDeveloper tutorial at http://www.oracle.com/technology/obe/obe1013jdev/10131/devdepandmanagingws/devdepandmanagingws.htm demonstrates creating a web service from a plain java class. I'm wondering:
- Is it possible to create a web service from a stateless session bean instead of a java class? If so, what's the proper way to do this in JDeveloper? When I tried doing so in JDeveloper 10.1.3.0.4 (SU5) using the J2EE Web Service wizard, the wizard did not list the session bean in the Component To Publish dropdown (it does list any java classes available in the project). I can proceed by manually typing in the name of the session bean. After the wizard completes though, the @Stateless annotation that had been in my session bean class code is removed and replaced by a @WebService annotation. The end result is that it looks like it made no difference whether I had tried to create the web service from a session bean or plain java class as the annotations in the resulting web service code are the same (although if I had started from a session bean, the class for the web service still implements the Local/Remote EJB interface that the session bean originally implemented).
- Assuming it's possible to create a web service from a stateless session bean, is there any advantage/disadvantage creating a web service from a java class vs a stateless session bean? I'm creating the web service from scratch so I also need to either build the java class or stateless session bean the web service would be based on from scratch too.
Thanks for any ideas about this.

Hi,
EJB Session beans (EJB 3.0) are deployed as WebServices by annotating the class with @WebService and the methds with @WebMethod (both tags require you to add the JSR-181 library to your project (available in the JDeveloper list of libraries)). Unlike the J2E WebService, the EJB session bean service is turned into a WebService upon deployment. This means you obtain teh WSDL file after deployment
- Assuming it's possible to create a web service from a stateless session bean, is there any advantage/disadvantage creating a web service from a java class vs a stateless session bean?
The difference is that EJB Session bean based web services are integrated with the J2EE container, which means that they can leverage container services like transaction handling, data sources, security, JMS etc.

I have found that my Mac Book Pro 15 inch late 2011 is slower than my PC Windows 7 for certain downloads, and working with iPhoto. Would adding RAM be helpful in speeding up this process. Currently I have the stock 4GB RAM, and storage 500GB HD drive.

I have found that my Mac Book Pro late 2011 15 inch is slower than I expected with certain downloads, or working with iPhoto than expected compared to my previous Windows 7 PC. Would adding RAM be of any value in speeding up the process?

how to tell if your mac needs more ram
