Include the code2webdisplay.jar file in your classpath

The API can be accessed in a simple way:

ISourceCodeParser parser = new JavaParser();   // This can also be: CPlusPlusParser, CSharpParser

parser.setCSSPath(”http://www.mysite.com/css/default.css”);
String html = parser.codeToHtml(new File(”c:/path/MyClass.java”));

Here is the code for the CSS file. Of course you may change the styles to whatever you like:

root {
display: block;
}

.keyword{
color:rgb(0,0,255);
font-family:’Arial’;
}

.comment{
color:rgb(0,255,0);
font-family:’Arial’;
}

.string{
color:rgb(255,0,0);
font-family:’Arial’;
}

.compiler_def{
color:rgb(0,200,50);
font-family:’Arial’;
}

.normal{
font-family:’Arial’;
}

body {
font-family: ‘Arial’; font-size:13
}

This project is written entirely in pure Java and no special JAR’s, J2EE stuff or third party libraries are required.

Technologies

Language: Pure Java Script
UI Library: YUI
Architecture: 100% Client Side

Typically log files may contain thousands of lines and can be quite large. This is why the log4j viewer was designed to handle all processing on the client side so there is not client-server interaction at all. Another reason is security issues. Since log files might contain confidential information, users prefer not to send logging information across the network.

Limitations

There is no safe way to parse a log4j file according to its pattern. This is a kind of reverse engineering which is not possible.

Consider the following example:
Log pattern = “%t %m%n”

This means that each line will contain the thread name a white space and the message followed by a new line.

Now, say we have a message where
thread name = “worker 1” and message = “hello world”
The result will be “worker 1 hello world“.
But the parser won’t know where the thread name ends and where the message starts. It could be any of the following combinations:
“worker“, “1 hello world”
“worker 1“, “hello world”
“worker 1 hello“, “world”

So as you can see the main limitations are using pattern attributes that contain white spaces in them. So here is the list of limitations that might cause log4j viewer to work improperly:

1. Message (%m) must be at the end of line
2. Pattern must end with a new line break (%n)
3. Multi line messages are not supported
4. Attributes that might contain spaces: for example (%t) are problematic. You can use them if they don’t contain spaces (like thread names without white spaces) but if the log line will have an extra white space it will probably mess up the output table.
5. Attributes that might be in the pattern but don’t always appear in the log: %x, %X usually work but might cause problems.

This seems like a long list of limitations but the log4j viewer does cover most common log4j cases.

So, enjoy!

About the company

SAP is the third largest software company in the world and a world leading company in enterprise software. SAP invented the ERP program (Enterprise Resource Planning) – as system planed to take care of all business and organizational resources: Human resources, Finance, Supply, Customer Relationships (CRM), Sales and distribution, and much more.

At 2001 SAP acquired the Israeli company TopTier (founded by Shai Agasi) for 400 million dollars. A short time before the acquisition I started working at TopTier and later on at SAP Labs as a C++ developer. TopTier’s product was an Enterprise Portal that became SAP Portal 5.0. The idea of the product is an intranet web application that allows employees to access any enterprise system in the organization through one unified location on the net, saving the effort of maintaining lots of clients for the different systems. During the years the lab grew from 120 employees to over 800 workers and the Portal was integrated into a much wider J2EE platform called SAP NetWeaver. This platform includes several modules that together provide a powerful integration environment:

SAP J2EE Engine – A powerful Enterprise J2EE Server

SAP Enterprise Portal (EP) – The SAP Portal

SAP BW/BI – A Business Warehouse system

Visual Composer – a modeling and composition tool

SAP NetWeaver Studio – The SAP Java IDE (based on Eclipse)

SAP XI – Exchange Infrastructure, an EAI system

Interesting projects I developed during the job

In the first two years I focused on the first version of the Portal called EP 5.0. This version was based mainly on the TopTier Portal and written in Microsoft technologies: VC++, COM/ATL, IIS, ASP and SQL Server. Our first task was to turn the Portal to a more generic platform. We added multi language support (that forced us to rewrite some parts of the code), and converted the Database layer to support Oracle instead of just SQL Server.

The Next tow years I joined the developing team working on the new SAP Portal (version 6). This product is the same portal used today in NetWeaver and is based purely on Java/J2EE. SAP did a quick move and converted the programmers from C++ MS oriented to true Java developers. A combination of recruiting new employees, natural turnovers, and professional courses turned the entire group to a Java development lab. The team I worked for was focused mainly on developing external connectors to a wide list of third party applications: Lotus Notes, Siebel, PeopleSoft, and other systems using mostly the JCA standard.

Israel Oil Refineries

About the company

ORL is Israel’s largest oil refinery and is traded on the Israeli stock exchange for over a billion dollars. The company provides most of the oil and energy products in the Israeli market.

Interesting projects and development during the job

ORL holds an SAP ERP system and external systems based on different technologies: ASP, VB, J2EE, and more. As a consultant I planned and developed interfaces to integrate the different systems to a unified environment based on Web Services.

Paz and Paz Refineries

About the company

At 2006 Paz, one of Israel’s leading energy companies acquired one of the 2 refiner centers originally owned by ROL. The acquisition for over 1 billion dollars caused a major challenge for both IT departments: ORL and Paz. On the one hand ORL needed to break up the enterprise IT systems that served both centers. And on the other side, Paz needed to integrate the IT systems with their main systems and make everything synchronized and working.

Interesting projects and development during the job

As a consultant I assisted both companies in converting their Java/J2EE applications, mostly based on Oracle JDeveloper/IAS and SAP NetWeaver and integrating them to other IT systems already in use. I also helped compile a road map and specs for some of the applications since Paz decided to rewrite some of the systems so they will suite better their needs.

Interesting projects

SAP Enterprise Portal at Haifa University

Haifa University is an Israeli academic institution. The university employs thousands of temporary workers, most of them as research assistance. Our project was developing a Portal based wokflow system, allowing the workers to report time sheets and managing the process of approvals by the different managers. The system included reports, alerts, and other controlling processes. The implementation was done with SAP NetWeaver Java WebDynpro technology, using the SAP R3 (ECC) and Oracle database as the data sources.
