Reference to the Sri Lankan materials, king Chandrabhanu Sridhamaraja is one of Javakan kings from Tambralinga kingdom, one the kingdoms in the prehistory period of Thai history, who had invaded Sri Lankan in 1247. However the Javaka has not occurred here for the first time. Many scholars identify Srivijaya with the Arabic Zabaj, which most scholars agree in equating with Javaka (in Pali texts) that appear in Indian sources.
The naval force of a Maharaja of Zabaj had ever played a major role in a legend recorded by an Arabic merchant name Sulaimaan in 851. He described the story of one silly Khmer king who defied the power of the Maharaja of Zabaj. Eventually how the end of the story was, he wrote down the Legend of the Maharaja of Zabaj.

Legend of the Maharaja of Zabaj

One day in a fit of jealousy, the Khmer ruler made the following remark in court.
"I have one desire that I would like to satisfy," said the young ruler.
"What is that desire, O King," inquired his faithful councillor.
"I wish to see before me on a plate," remarked the monarch, "the head of the King of Zabaj."
"I do not wish, O King, that my sovereign should express such a desire,” answered the minister. “The Khmer and Zabaj have never manifested hatred towards each other, either in words or in acts. Zabaj has never done us any harm. What the King has said should not be repeated."
Angered by this sage advice, the Khmer ruler raised his voice and repeated his desire so that all of the generals and nobles who were present at court could hear him. Word of the young ruler’s impetuous outburst passed from mouth to mouth until it finally arrived at the court of the Maharaja of Zabaj. Upon hearing the words of the Khmer ruler, the Maharaja ordered his councillor to prepare a thousand ships for departure. When the fleet was ready, the Maharaja himself went aboard and announced to the crowd on shore that he would be making a pleasure trip amongst his islands. Once at sea, however, the Maharaja orders the armada to proceed to the capital of the Khmer ruler, where his troops took the Khmers by surprise, seized the city, and surrounded the palace. After the Khmer ruler had been captured, he was brought before the Maharaja of Zabaj.
"What caused you to form a desire which was not in your power to satisfy, which would not have given you happiness if you had realized it, and would not even have been justified if it had been easily realizable?" inquired the Maharaja of Zabaj.
Since the Khmer king had nothing to say in return, the Maharaja of Zabaj continued. "You have manifested the desire to see before you my head on a plate. If you also had wished to seize my country and my kingdom or even only to ravage a part of it, I would have done the same to you. But since you have only expressed the first of these desires, I am going to apply to you the treatment you wished to apply to me, and I will then return to my country without taking anything belonging to the Khmer, either of great or small value."
When the Maharaja returned to his own palace back home, he seated himself on the throne. Set before him was a plate upon which rested the head of the former Khmer king.

Conclusion

Some scholars have sought to link this Maharaja of Zabaj with the Sailendra king of Java. However there are few evidences to prove that the Maharaja of Zabaj is the same king of Sailendra. While the Javakan king of Tambralinga had been linked direct to Maharaja of Zabaj. Therefore the Javaka had occurred in The history since 9^th century. In addition Javakan king also occurred in the history of Lavo kingdom, one the kingdoms in the prehistory period of Thai history. At a point in time when Sri Vijaya had been the established leader in the Southeast Asian region for about 100 years, the Sailendra Kingdom of Java emerged. ...
