Javaservice to add two numbers

[Guest]

Any One guide me how to write a javaservice to add two numbers

[reamon]

The simplest way is to call pub.math:addInts or addFloats in your FLOW service. No need to use Java for this.

Hello,

For educational purposes, you can look at an article created by none other that Rob for adding and computer representation issues. This article, Float and Double: 1/3 + 2/3 gives an example on the first page. Good day.

Thanks for the Replies.
I am more of a Javaguy and want to develop custom services using Developer IDE ,But my IDE says “Failed to Compile Service” and i changed the to

watt.server.compile=C:\Program Files\webMethods6\jvm\win142\bin\javac -classpath {0} -d {1} {2}
watt.server.compile.unicode=C:\Program Files\webMethods6\jvm\win142\bin\javac -encoding Unicode -classpath {0} -d {1} {2}

but still i am unable to compile my service.

can u please help

These are the two errors i see on my server

Reddy,

You will see the error,when the java service is not complied but it saves in the developmer javaservice.So please make sure the java service is complied and class will be created internally,you will not see the error again.

Execute the java service on the IS OS level if the JVM is not installed on your client developmer machine.

HTH,

Make some meaningless change to the service (delete a ; and then type it back in) and save. That should compile the service for you.

“I am more of a Javaguy and want to develop custom services using Developer IDE…”

I’ll offer this piece of advice: resist the urge to write Java services. You’ll want to develop Java services because you know how to write Java but you’ll be far better off in the long run if you stick mostly with FLOW. There are a couple of threads on this forum that talk about this a little. Writing FLOW services has a learning curve but it is definitely worth the effort.

Hello,

In the webMethods IS service world, programming in java actually adds less to your working environment if used frequently. Java has its use in providing a strong method for creating and manipulating objects. There are very few properties of a document or field that you will want. Most of your operations will be functional like adding fields, or splitting a document. So you will be acting on the values and your mental models will lean towards this functional state as your projects progress.

Of course, programming some algorithms in Java may optimize some executions, but these all tend to be at the end of your project. The other time for Java’s use is when there just isn’t any such method. Clean and powerful date and file handling services are not directly provided with your installation and even with PSUtilities, you may still need to do cryptic data manipulations.

I, like you (maybe) and many to come after, think in Java (and other languages) and I knew I could create fast solutions without yet worrying about “flow”. But jumping in and out of java brings more headaches to you and your team when debugging. You can’t step line by line in a java service line you can in a flow. If you can partly debug your java code in a separate IDE, you have a large harness to setup for tests. If you use the built in IDE ( < 6.0.1 is all I can comment on), you don’t have anything more really that notepad and a background compiler.

The “flow” provides visual development and debugging and get is the best setup for gluing other services together. So if you can, go with the flow.

Ah, may have been more than needed (or partly wrong), but today I felt like ranting. Good day.

Thanks Seniors,

I am a confused lili bit regarding the path to choose to excel in the field of Integration ,I have learnt Mq,Message Broker ,tibco Ems and webMethods and just been out of college.I have not worked in any company till now but got softwares and been practising them.

now i am starting to search for a job and I dont want to get stuck in any of these for rest of my life and want to become an EAI architect in future.

most of the jobs are consulting or permanent and they stuck on one tool in their enterprise.

i want your advices on what best i can do to become an architect.

Thanks in advance

Hello,

Architecture deals with structures. Primarily an architects need comes into play most with large and/or complex structures. They are wanted to help speed the implementation of common practices that help produce solid results or create a custom design that is not overly brittle because of a new initiative. These hold weight whether of not the raw resources are concrete and beams or java and flow.

I would probably first suggest the advantage website (webMethods focus). Since it seems to be your current tool set, there is no need to stray to far into the generalization of the whole thing. There is a core of fundamentals that you may want to explore like patterns of functional programming, or common integration practices. Beyond that, focus can make you strong and at a point you will realize that you can move your knowledge to a new product base with little trouble.

Unless you really have the time, try not to do something like learning JBoss, IBM, Sun, weMethods, BEA and Oracle products all at the same time to keep from being “left out”. You seem to already be well verse in different products and should have seen where a simile could have been made.

You may want to subscribe to a magazine like Integration World. There are more polished reviews of products and their strengths and weaknesses. I would also make google and this sites search your friend. We tend to talk about a good number of the same topics over and over and this one is no exception. On google I did “how to become a software architect”. I liked these links:
From here to software architecture
Institute of Software Architects
How to be a Programmer: A Short, Comprehensive, and Personal Summary

Designing and Building by pre-made blocks and services from a confirmed and reliable source is a strong portion of your architecture time-frame for projects. Good day.
