118 Line 3 makes a qualified name instance for Clustal JABA web service. <br />
\r
119 Line 4 creates a service instance.<br />
\r
120 Line 5 makes a connection to the server. </p>
\r

145 <h3><a name="defalign" id="defalign"></a>Aligning sequences </h3>
\r
146 <p>Given that <span class="hightlight">msaws</span> is web service proxy, created as described in "Connecting to JABAWS" section, the actual alignment can be obtained as follows: </p>
\r
147 <p class="code">1) List<FastaSequence> fastalist = SequenceUtil.readFasta(new FileInputStream(file));<br />
\r
148 2) String jobId = msaws.align(fastalist); <br />
\r
149 3) Alignment alignment = msaws.getResult(jobId);</p>
\r
150 <p>Line one loads FASTA sequence from the file<br />
\r
151 Line two submits them to web service represented by msaws proxy <br />
\r
152 Line three retrieves the alignment from a web service. This line will block the execution until the result is available. Use this with caution. In general, you should make sure that the calculation has been completed before attempting retrieving results. This is to avoid keeping the connection to the server on hold for a prolonged periods of time. While this may be ok with your local server, our public server (<a href="http://www.compbio.dundee.ac.uk/jabaws">www.compbio.dundee.ac.uk/jabaws</a>) will not let you hold the connection for longer than 10 minutes. This is done to prevent excessive load on the server. The next section describes how to check the status of the calculation.<br />
\r
153 Methods and classes mentioned in the excerpt are available from the JABAWS client library. </p>
\r
154 <h3><a name="checkresults" id="checkresults"></a>Checking the status of the calculation </h3>
\r
155 <p> You may have noticed that there was no pause between submitting the job and retrieving of the results. This is because <span class="hightlight">getResult(jobId)</span> method block the processing until the calculation is completed. However, taking into account that the connection holds server resources, our public server (<a href="http://www.compbio.dundee.ac.uk/jabaws">www.compbio.dundee.ac.uk/jabaws</a>) is configured to reset the connection after 10 minutes of waiting. To work around the connection reset you are encouraged to check whether the calculation has been completed before accessing the results. You can do it like this: </p>
\r
156 <p> <span class="code">while (msaws.getJobStatus(jobId) != JobStatus.FINISHED) {<br />
\r
157 Thread.sleep(2000); // wait two seconds, then recheck the status <br />
\r
159 <h3><a name="presetalign" id="presetalign"></a>Aligning with presets</h3>
\r
160 <p class="code">1) PresetManager presetman = msaws.getPresets();<br />
\r
161 2) Preset preset = presetman.getPresetByName(presetName);<br />
\r
162 3) List<FastaSequence> fastalist = SequenceUtil.readFasta(new FileInputStream(file));<br />
\r
163 4) String jobId = msaws.presetAlign(fastalist, preset);<br />
\r
164 5) Alignment alignment = msaws.getResult(jobId);</p>
\r
165 <p>Line one obtains the lists of presets supported by a web service.<br />
\r
166 Line two return a particular Preset
\r
168 Lines three to five are doing the same job as in the first <a href="#defalign"> aligning sequences example</a>.</p>
\r
169 <h3><a name="customalign" id="customalign"></a>Aligning with custom parameters</h3>
\r
170 <p class="code"> 1) RunnerConfig options = msaws.getRunnerOptions();<br />
\r
171 2) Argument matrix = options.getArgument("MATRIX");<br />
\r
172 3) matrix.setValue("PAM300");<br />
\r
173 4) Argument gapopenpenalty = options.getArgument("GAPOPEN");<br />
\r
174 5) gapopenpenalty.setValue("20");<br />
\r
175 6) List<Argument> arguments = new ArrayList<Argument>(); <br />
\r
176 7) arguments.add(matrix);
\r
177 arguments.add(gapopenpenalty);<br />
\r
178 8) List<FastaSequence> fastalist = SequenceUtil.readFasta(new FileInputStream(file));<br />
\r
179 9) String jobId = msaws.customAlign(fastalist, arguments);<br />
\r
180 10) Alignment alignment = msaws.getResult(jobId);</p>
\r
181 <p>Line one obtains the <span class="hightlight">RunnerConfig</span> object that holds information on supported parameters and their values<br />
\r
182 Line two retrieve a particular parameter from the holder by its name<br />
\r
183 Lines three sets a value to this parameter which will be used in the calculation. <br />
\r
184 Line four and five do the same but for another parameter<br />
\r
185 Line 6 makes a List to hold the parameters <br />
\r
186 Line seven puts the parameters into that list<br />
\r
188 and ten is the same as in previous examples<br />
\r
189 Line nine submit an alignment request with the sequences and the parameters <br />
\r
190 The names of all the parameters supported by a web service e.g. "PAM300" can be obtained using <span class="hightlight">options.getArguments() </span>method. Further details on the methods available from <span class="hightlight">RunnerConfig</span> object are available from the <a href="dm_javadoc/index.html">javadoc</a>. </p>
\r
191 <h3><a name="writingaltofile" id="writingaltofile"></a>Writing alignments to a file</h3>
\r
192 <p>There is a utility method in the client library that does exactly that. </p>
\r
193 <p> <span class="code">Alignment alignment = align(...) <br />
\r
194 FileOutputStream outStream = new FileOutputStream(file);<br />
\r
195 ClustalAlignmentUtil.writeClustalAlignment(outStream, align);</span></p>
\r
196 <h3><a name="compex" id="compex"></a>A complete client example </h3>
\r
197 <p>Finally, a complete example of the program that connects to JABAWS Clustal service and aligns sequences using one of the Clustal web service preset. Three is also a <a href="Example_template.pdf">PDF version</a> of this example with syntax highlighted. The text comments are commented by block style comments e.g. /* comment */, the alternatives given in the code are line commented // comment. You may want to remove line style comments to test alternatives of the functions. All you need for this to work is a <a href="download.html">JABAWS binary client</a>. Please make sure that the client is in the Java class path before running this example.</p>

332 <p>JABAWS are the standard <a href="http://jax-ws.java.net/">JAX-WS</a> SOAP web services, which are <a href="http://www.ws-i.org/">WS-I</a> basic profile compatible. This means that you could use whatever tool your language has to work with web services. Below is how you can generate portable artifacts to work with JABAWS from Java.
